8 Operation Details

8.1. Basic Function

Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating mode, the microcomputer maintains the set temperature by measuring the temperature of the environment and performing temperature shifting. The compressor at outdoor unit is operating following the frequency instructed by the microcomputer at indoor unit that judging the condition according to internal setting temperature and intake air temperature.

8.1.1. Internal Setting Temperature

Once the operation starts, remote control setting temperature will be taken as base value for temperature shifting processes. These shifting processes are depending on the air conditioner settings and the operation environment. The final shifted value will be used as internal setting temperature and it is updated continuously whenever the electrical power is supplied to the unit.

11 Installation And Servicing Air Conditioner Using R410A

11.1. Outline

11.1.1. About R410A Refrigerant

1. Converting air conditioners to R410A Since it was declared in1974 that chlorofluorocarbons (CFC), hydro chlorofluorocarbons (HCFC) and other substances pose a destructive danger to the ozone layer in the earth´s upper stratosphere (20 to 40 km above the earth), measures have been taken around the world to prevent this destruction. The R22 refrigerant which has conventionally been used in ACs is an HCFC refrigerant and, therefore, possesses this ozonedestroying potential. International regulations (the Montreal Protocol on Ozone-Damaging Substances) and the domestic laws of various countries call for the early substitution of R22 by a refrigerant which will not harm the ozone layer.

In ACs, the HFC refrigerant which has become the mainstream alternative is called R410A.Compared with R22, the

•

pressure of R410A is approximately 1.6 times as high at the same refrigerant temperature, but the energy efficiency is about the same. Consisting of hydrogen (H), fluorine (F) and carbon (C), R410A is an HFC refrigerant. Anothe r typical HFC refrigerant is R407C. While the energy efficiency of R407C is somewhat inferior to that of R410A , it offers the advantage of having pressure characteristics which are about the same as those of R22, and is used mainly in packaged ACs.

2. The characteristics of HFC (R410A) refrigerants

a. Chemical characteristics

The chemical characteristics of R410A are similar to those of R22 in that both are chemically stable, non-flammable refrigerants with low toxicity. However, just like R22, the specific gravity of R410A gas is heavier than that of air. Because of this, it can cause an oxygen deficiency if it leaks into a closed room since it collects in the lower area of the room. It also generates toxic gas when it is directly exposed to a flame, so it must be used in a well ventilated environment where it will not collect.

R410A R22

44.4 kg/m

b. Compositional change (pseudo-azeotropic characteristics)

R410A is a pseudo-azeotropic mixture comprising the two components R32 and R125. Multi-component refrigerants with these chemical characteristics exhibit little compositional change even from phase changes due to vaporization (or condensation), which means that there is little change in the circulating refrigerant composition even when the refrigerant leaks from the gaseous section of the piping. Accordingly, R410A can be handled in almost the same manner as the single-component refrigerant R22. However, when charging, because there is a slight change in composition between the gas phase and the liquid phase inside a cylinde r or other container, charging should basically begin with the liquid side.

c. Pressure characteristics

As seen in Table 2, the gas pressure of R410A is approximately 1.6 times as high as that of R22 at the same refrigerant temperature, which means that special R410A tools and materials with high-pressure specifications must be used for all refrigerant piping work and servicing.

d. R410A refrigerating machine oil

Conventionally, mineral oil or a synthetic oil such as alkylbe nzene has been used for R22 refrigerating machine oil. Because of the poor compatibility between R410A and conventional oils like mineral oil, however, there is a tendency for the refrigerating machine oil to collect in the refrigerating cycle. For this reason, polyester and other synthetic oils which have a high compatibility with R410A are used as refrigerating machine oil. Because of the high hygroscopic property of synthetic oil, more care must be taken in its handling than was necessary with conventional refrigerating machine oils. Also, these synthetic oils will degrade if mixed with mineral oil or alkylbenzene, causing clogging in capillary tubes or compressor malfunction. Do not mix them under any circumstances.

11.1.2. Safety Measures When Installing/Servicing Refrigerant Piping

Cause the gas pressure of R410A is approximately 1.6 times as high as that of R22, a mistake in installation or servicing could result in a major accident. It is essential that you use R410A tools and materials, and that you observe the following precautions to ensure safety.

1. Do not use any refrigerant other than R410A in ACs that have been used with R410A.

2. If any refrigerant gas leaks while you are working, ventilate the room. Toxic gas may be generated if refrigerant gas is expose d to a direct flame.

3. When installing or transferring an AC, do not allow any air or substance other than R410A to mix into the refrigeration cycle. If it does, the pressure in the refrigeration cycle can become abnormally high, possibly causing an explosion and/or injury.

4. After finishing the installation, check to make sure there is no refrigerant gas leaking.

5. When installing or transferring an AC, follow the instructions in the installation instructions carefully. Incorrect installation can result in an abnormal refrigeration cycle or water leakage, electric shock, fire, etc.

6. Do not perform any alterations on the AC unit under any circumstances. Have all repair work done by a specialist. Incorrect repairs can result in an water leakage, electric shock, fire, etc.

11.2. Tools For Installing/Servicing Refrigerant Piping

11.2.1. Necessary Tools

In order to prevent an R410A AC from mistakenly being charged with any other refrigerant, the diameter of the 3-way valve service port on the outdoor unit has been changed. Also, to increase its ability to withstand pressure, the opposing dimensions have been changed for the refrigerant pipe flaring size and flare nut. Accordingly, when installing or servicing refrigerant piping, you must have both the R410A and ordinary tools listed below.

Type of work Ordinary tools R410A tools

Flaring Flaring tool (clutch type), pipe cutter,

Bending, connecting pipes Torque wrench (nominal diameter 1/4,

Air purging Vacuum pump. Hexagonal wrench

Gas leak inspection Gas leak inspection fluid or soapy water Electric gas leak detector for HFC

*1) You can use the conventional (R22) flaring tool. If you need to buy a new tool, buy the R410A type.

*2) Use when it is necessary to detect small gas leaks.

For other installation work, you should have the usual tools, such as screwdrivers (+,-), a metal-cutting saw, an electrical drill, a hole core drill (65 or 70 dia.), a tape measure, a level, a thermometer, a clamp meter, an insulation tester, a voltmeter, etc.

*1) Always replace the dryer of the outdoor unit at the same time. The replacement dryer is wrapped in a vacuum pack. Replace it last among the refrigerating cycle parts. Start brazing as soon as you have opened the vacuum pack, and begin the vacuuming operation within 2 hours.

11.2.2. R410A Tools

1. Copper tube gauge for clearance adjustment (used when flaring with the conventional flaring tool (clutch type))

This gauge makes it easy to set the clearance for the

•

copper tube to 1.0-1.5 mm from the clamp bar of the flaring tool.

2. Flaring tool (clutch type)

In the R410A flaring tool, the receiving hole for the

•

clamp bar is enlarged so the clearance from the clamp bar can be set to 0-0.5 mm, and the spring inside the tool is strengthened to increase the strength of the pipeexpanding torque. This flaring tools can also be used with R22 piping, so we recommend that you select it if you are buying a new flaring tool.

4. Manifold gauge

Because the pressure is higher for the R410A type, the conventional type cannot be used.

5. Charging hose

The pressure resistance of the charging hose has been

•

raised to match the higher pressure of R410A. The hose material has also been changed to suit HFC use, and the size of the fitting has been changed to match the manifold ports.

6. Vacuum pump adaptor

When using a vacuum pump for R410A , it is necessary

•

to install an electromagnetic valve to prevent the vacuum pump oil from flowing back into the charging hose. The vacuum pump adaptor is installed for that purpose. if the vacuum pump oil (mineral oil) becomes mixed with R410A, it will damage the unit.

7. Electric gas leak detector for HFC refrigerant

The leak detector and halide torch that were used with

•

CFC and HCFC cannot be used with R410A (because there is no chlorine in the refrigerant).

The present R134a leak detector can be used, but the

•

detection sensitivity will be lower (setting the sensitivity for R134a at 1, the level for R410A will drop to 0.6).

For detecting small amounts of gas leakage, use the

•

electric gas leak detector for HFC refrigerant. (Detection sensitivity with R410A is about 23 g/year).

Fig. 5 Vacuum pump adaptor

Fig. 6 Electric gas leak detector for HFC refrigerant

8. Electronic scale for refrigerant charging

Because of the high pressure and fast vaporizing speed

•

of R410A, the refrigerant cannot be held in a liquid phase inside the charging cylinder when charging is done using the charging cylinder method, causing bubbles to form in the measurement scale glass and making it difficult to see the reading. (Naturally, the conventional R22 charging cylinder cannot be used because of the differences in the pressure resistance, scale gradation, connecting port size, etc.)

The electronic scale has been strengthened by using a

•

structure in which the weight detector for the refrigerant cylinder is held by four supports. It is also equipped with two connection ports, one for R22 (7/16 UNF, 20 threads) and one for R410A (1/2 UNF, 20 threads), so it can also be used for conventional refrigerant charging.

There are two types of electronic scales, one for 10-kg

•

cylinders and one for 20-kg cylinders. (The 10-kg cylinder is recommended.)

Refrigerant charging is done manually by opening and closing the valve.

9. Refrigerant cylinders

The R410A cylinders are labeled with the refrigerant

•

name, and the coating color of the cylinder protector is pink, which is the color stipulated by ARI of the U.S.

Cylinders equipped with a siphon tube are available to

•

allow the cylinder to stand upright for liquid refrigerant charging.

10. Charging orifice and packing for refrigerant cylinders

The charging orifice must match the size of the charging

•

hose fitting (1/2 UNF, 20 threads).

The packing must also be made of an HFC-resistant

•

material.

11.3. Refrigerant Piping Work

11.3.1. Piping Materials

It is recommended that you use copper and copper alloy jointless pipes with a maximum oil adherence of 40 mg/10m. Do not use pipes that are crushed, deformed, or discolored (especially the inside surface). If these inferior pipes are used, impurities may clog the expansion valves or capillaries. Because the pressure of ACs using R410A is higher than those using R22, it is essential that you select materials that are appropriate for these standards. The thickness of the copper tubing used for R410A is shown in Table 10. Please be aware that tubing with a thickness of only 0.7 mm is also available on the market, but this should never be used.

11.3.2. Processing and Connecting Piping Materials

When working with refrigerant piping, the following points must be carefully observed: no moisture od dust must be allowed to enter the piping, and there must be no refrigerant leaks.

1. Procedure and precautions for flaring work

a. Cut the pipe

Use a pipe cutter, and cut slowly so the pipe will not be deformed.

b. Remove burrs and clean shavings from the cut surface

If the shape of the pipe end is poor after removing burrs, or if shavings adhere to the flared area, it may lead to refrigerant leaks. To prevent this, turn the cut surface downward and remove burrs, then clean the surface, carefully.

c. Insert the flare nut (be sure to use the same nut that is

used on the AC unit)

d. Flaring

Check the clamp bar and the cleanliness of the copper pipe. Be sure to use the clamp bar to do the flaring with accuracy. Use either an R410A flaring tool, or a conventional flaring tool. flaring tools come in differen t sizes, so be sure to check the size before using. When using a conventional flaring tool, use the copper pipe gauge for clearance adjustment, etc., to ensure the correct A dimension (see Fig. 10)

2. Procedure and precautions for flare connection

a. Check to make sure there is no scratches, dust, etc., on the flare and union.

b. Align the flared surface with the axial center of the union.

c. Use a torque wrench, and tighten to the specified torque. The tightening torque for R410A is the same as the conventional

torque value for R22. Be careful, because if the torque is too weak, it may lead to a gas leak. If it is too strong, it may split the flare nut or make it impossible to remove the flare nut.

11.3.3. Storing and Managing Piping Materials

1. Types of piping and their storage The following is a general classification of the refrigerant pipe materials used for ACs.

Because the gas pressure of R410A is approximately 1.6 times as high as that of R22, copper pipes with the thickness shown in Table 10, and with minimal impurities must be used. Care must also be taken during storage to ensure that pipes are not crushed, deformed, or scratched, and that no dust, moisture or other substance enters the pipe interior. When storing sheathed copper pipes or plain copper pipes, seal the openings by pinching or taping them securely.

2. Makings and management

a. Sheathed copper pipes and copper-element pipes

When using these pipes, check to make sure that they are the stipulated thickness. For flare nuts, be sure to used the same nut that is used on the AC unit.

CS-E9DKDW CU-E9DKD / CS-E12DKD W CU-E12DKD

b. Copper pipes

Use only copper pipes with the thickness given in table 10, and with minimal impurities. Becaus e the surface of the pipe is exposed, you should take special care, and also take measures such as marking the pipes to make sure they are easily distinguished from other piping materials, to prevent mistaken use.

3. Precautions during refrigerant piping work Take the following precautions on-site when connecting pipes. (Keep in mind that the need to control the entry of moisture and dust is even more important that in conventional piping).

a. Keep the open ends of all pipes sealed until connection with AC equipment is complete.

b. Take special care when doing piping work on rainy days. The entering of moisture will degrade the refrigerating machine oil,

and lead to malfunctions in the equipment.

c. Complete all pipe connections in as short a time as possible. If the pipe must be left standing for a long time after removing

the seal, it must be thoroughly purged with nitrogen, or dried with a vacuum pump.

11.4. Installation, Transferring, Servicing

11.4.1. Inspecting Gas Leaks with a Vacuum Pump for New Installations (Using New

Refrigerant Piping)

1. From the viewpoint of protecting the global environment, please do not release refrigerant into the atmosphere.

a. Connect the projecting side (pin-pushing side) of the charging hose for the manifold gauge to the service port of the 3-way

valve. (1)

b. Fully open the handle Lo of the manifold gauge and run the vacuum pump. (2) (If the needle of the low-pressure gauge

instantly reaches vacuum, re-check step a).)

c. Continue the vacuum process for at least 15 minutes, then check to make sure the low-pressure gauge has reached -0.1

MPa (-76 cmHg). Once the vacuum process has finished, fully close the handle Lo of the manifold gauge and stop the vacuum pump operation, then remove the charging hose that is connected to the vacuum pump adaptor. (Leave the unit in that conditio n for 1-2 minutes, and make sure that the needle of the manifold gauge does not return.) (2) and (3)

d. Turn the valve stem of the 2-way valve 90° counter-clockwise to open it, then, after 10 seconds, close it and inspect for a

gas leak (4)

e. Remove the charging hose from the 3-way valve service port, then open both the 2-way valve and 3-way valve. (1) (4) (Turn

the valve stem in the counter-clockwise direction until it gently makes contact. Do not turn it forcefully).

f. Tighten the service port cap with a torque wrench (18 N.m (1.8 kgf.m)). (5) Then tighten the 2-way valve and 3-way valve

caps with a torque wrench (42 N.m (4.2 kgf.m)) or (55 N.m (5.5 kgf.m)). (6)

g. After attaching each of the caps, inspect for a gas leak around the cap area. (5) (6)

Precautions

Be sure to read the instructions for the vacuum pump,

•

vacuum pump adaptor and manifold gauge prior to use, and follow the instructions carefully.

Make sure that the vacuum pump is filled with oil up to

•

the designated line on the oil gauge.

The gas pressure back flow prevention valve on the

•

charging hose is generally open during use. When you are removing the charging hose from the service port, it will come off more easily if you close this valve.

11.4.2. Transferring (Using New Refrigerant Piping)

1. Removing the unit

a. Collecting the refrigerant into the outdoor unit by pumping down

The refrigerant can be collected into the outdoor unit (pumping down) by pressing the TEST RUN button, even when the temperature of the room is low.

Check to make sure that the valve stems of the 2-way valve and 3-way valve have been opened by turning them counter-

•

clockwise. (Remove the valve stem caps and check to see that the valve stems are fully opened position. Always use a hex wrench (with 4-mm opposing sides) to operate the valve stems.)

Press the TEST RUN button on the indoor unit, and allow preliminary operation for 5-6 minutes. (TEST RUN mode)

•

After stopping the operation, let the unit sit for about 3 minutes, then close the 2-way valve by turning the valve stem in

•

the clockwise direction.

Press the TEST RUN button on the indoor unit again, and after 2-3 minutes of operation, turn the valve stem of the 3-

•

way valve quickly in the clockwise direction to close it, then stop the operation.

Tighten the caps of the 2-way valve and 3-way valve to the stipulated torque.

•

Remove the connection pipes (liquid side and gas side).

•

b. Removing the indoor and outdoor units.

Disconnect the pipes and connecting electric cables from between the indoor and outdoor units.

•

Put capped flare nuts onto all of the pipe connections of the indoor and outdoor units, to make sure no dust or other

•

foreign matter enters.

Remove the indoor and outdoor units.

•

2. Installing the unit Install the unit using new refrigerant piping. Follow the instructions in section 4.1 to evacuate the pipes connecting the indoor and outdoor units, and the pipes of the indoor unit, and check for gas leaks.

11.4.3. AC Units Replacement (Using Existing Refrigerant Piping)

When replacing an R410A AC unit with another R410A AC unit, you should re-flare the refrigerant piping. Even though the replacement AC unit uses the R410A, problems occur when, for example, either the AC unit maker or the refrigerating machine oil is differen t. When replacing an R22 AC unit with an R410A AC unit, the following checks and cleaning procedures are necessary but are difficult to do because of the chemical characteristics of the refrigerating machine oil (as described in items c) and d) of section

About R410A Refrigerant

1. Piping check Because of the different pressure characteristics of R22 and R410A, the design pressure for the equipment is 1.6 times different. the wall thickness of the piping must comply with that shown in Table 10, but this is not easy to check. Also, even if the thickness is correct, there may be flattened or bent portions midway through the piping due to sharp curves. Buried sections of the piping also cannot be checked.

2. Pipe cleaning A large quantity of refrigerating machine oil (mineral oil) adheres to existing pipes due to the refrigeration cycle circulation. If the pipes are used just as they are for the R410A cycle, the capacity will be lowered due to the incompatibility of this oil with the R410A, or irregularities may occur in the refrigeration cycle. For this reason, the piping must be thoroughly cleaned, but this is difficult with the present technology.

). In this case, you should use new refrigerant piping rather than the existing piping.

11.4.4. Refrigerant Compatibility (Using R410A Refrigerant in R22 ACs and Vice Versa)

Do not operate an existing R22 AC with the new R410A refrigerant. Doing so would result in improper functioning of the equipment or malfunction, and might lead to a major accident such as an explosion in the refrigeration cycle. Similarly, do not operate an R410A AC with R22 refrigerant. The chemical reaction between the refrigerating machine oil used in R410A ACs and the chlorine that is contained in R22 would cause the refrigerating machine oil to degrade and lead to malfunction.

11.4.5. Recharging Refrigerant During Servicing

When recharging is necessary, insert the specified amount of new refrigerant in accordance with the following procedure.

1. Connect the charging hose to the service port of the outdoor unit.

2. Connect the charging hose to the vacuum pump adaptor. At this time, fully open the 2-way valve and 3-way valve.

3. Fully open the handle Lo of the manifold gauge, turn on the power of the vacuum pump and continue the vacuum process for at least one hour.

4. Confirm that the low pressure gauge shows a reading of -0.1 Mpa (-76 cmHg), then fully close the handle Lo, and turn off the vacuum pump. Wait for 1-2 minutes, then check to make sure that the needle of the Low pressure gauge has not returned. See Fig. 13 for the remaining steps of this procedure.

5. Set the refrigerant cylinder onto the electronic scale, then connect the hose the cylinder and to the connection port for the electronic scale. (1)(2)

Precaution:

Be sure to set up the cylinde r for liquid charging. If you use a cylinder equipped with a siphon tube, you can charge the liquid without having to turn the cylinder around

6. Remove the charging hose of the manifold gauge from the vacuum pump adaptor, and connect it to the connection port of the electronic scale. (2)(3)

7. Open the valve of the refrigerant cylinder, then open the charging valve slightly and close it. Next, press the check valve of the manifold gauge and purge the air. (2)(4) (Watch the liquid refrigerant closely at this point.)

8. After adjusting the electronic scale to zero, open the charging valve, then open the valve Lo of the manifold gauge and charge with the liquid refrigerant. (2)(5) (Be sure to read the operating instructions for the electronic scale.)

9. If you cannot charge the stipulated amount, operate the unit in the cooling mode while charging a little of the liquid at a time (about 150 g/time as a guideline). If the charging amount is insufficient from one operation, wait about one minute, then use the same procedure to do the liquid charging again.

Precaution:

Never use the gas side to allow a larger amount of liquid refrigerant to be charged while operating the unit.

10. Close the chargin g valve, and after charging the liquid refrigerant inside the charging hose, fully close the valve Lo of the manifold gauge, and stop the operation of the unit. (2)(5)

11. Quickly remove the chargin g hose from the service port. (6) If you stop midway through, the refrigerant that is in the cycle will be discharged.

12. After putting on the caps for the service port and operating valve, inspect around the caps for a gas leak. (6)(7)

11.4.6. Brazing

As brazing requires sophisticated techniques and experiences, it must be performed by a qualified person. In order to prevent the oxide film from occurring in the pipe interior during brazing, it is effective to proceed with brazing while letting dry nitrogen gas (N

1. Attach a reducing valve to the nitrogen gas cylinder.

2. Apply a seal onto the clearance between the piping and inserted pipe for the nitrogen gas in order to prevent the nitrogen gas from flowing backward.

3. When the nitrogen gas is flowing, be sure to keep the piping end open.

4. Adjust the flow rate of nitrogen gas so that it is lower than 0.05 m

5. After taking the steps above, keep the nitrogen gas flowing until the piping cools down to a certain extent (i.e. temperature at which pipes are touchable with finger).

6. Completely remove the flux after brazing.

) flow.

/h, or 0.02 MPa (0.2 kgf/cm2) by means of the reducing valve.

Fig. 14 Prevention of Oxidation during Brazing

Cautions during brazing

1. General Cautions

a. The brazing strength should be high as required.

b. After operation, airtightness should be kept under pressurized condition.

c. During brazing do not allow component materials to become damaged due to overheating.

d. The refrigerant pipe work should not become blocked with scale or flux.

e. The brazed part should not restrict the flow in the refrigerant circuit.

f. No corrosion should occur from the brazed part.

2. Prevention of Overheating

Due to heating, the interior and exterior surfaces of treated metal may oxidize. Especially, when the interior of the refrigerant circuit oxidizes due to overheating, scale occurs and stays in the circuit as dust, thus exerting a fatally adverse effect. So, make brazing at adequate brazing temperature and with minimum of heating area.

3. Overheating Protection

In order to prevent components near the brazed part from overheating damage or quality deterioration due to flame or heat, take adequate steps for protection such as (1) by shielding with a metal plate, (2) by using a wet cloth, and (3) by means of heat absorbent.

4. Movement during Brazing

Eliminate all vibration during brazing to protect brazed joints from cracking and breakage.

5. Oxidation Preventative

In order to improve the brazing efficiency, various types of antioxidant are available on the market. However, the constituents of these are widely varied, and some are anticipated to corrode the piping materials, or adversely affect HFC refrigerant, lubricating oil, etc. Exercise care when using an oxidation preventive.

11.4.7. Servicing Tips

The drier must also be replaced whenever replacing the refrigerant cycle parts. Replacing the refrigerant cycle parts first before replacing the drier. The drier is supplied in a vacuum pack. Perform brazing immediately after opening the vacuum pack, and then start the vacuum within two hours. In addition, the drier also needs to be replaced when the refrigerant has leaked completely. (Applicable for drier models only)

12 Servicing Information

Caution:

• Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70°F(30-40°C) higher. Please use a high temperature soldering iron. In case of the soldering iron with temperature control, please set it to 700 ± 20°F (370 ± 10°C).

• Pb free solder will tend to splash when heated too high (about 1100° F/600°C).

12.1. Troubleshooting
