REFRIGERANT PIPING WORK

Refrigerant piping is important in particular. Refrigeration cycle of the split air conditioner is realized by the perfect piping work.

Piping length and elevation

If the piping is too long, both the capacity and reliability of unit will drop. As the number of bends increase, resistance to flow of refrigerant system increases, thus lowering cooling capacity and as a result the compressor may become defective. Always choose the shortest path and follow the recommendation as tabulated below.

Piping Connection

• Do not use contaminated or damaged copper tubing. If any piping, evaporator or condenser had been exposed or had been

opened for 15 seconds or more, then vacuum and purge with field supplied refrigerant. Generally, do not remove plastic, rubber plugs and brass nuts from the valves, fittings, tubing and coils until it is ready to connect suction or liquid line into valves or fittings.

• If any brazing work is required, ensure that nitrogen gas is passed through coil and joints while the brazing work is being

done. This will eliminate soot formation on the inside wall of copper tubings.

• Cut the pipe stages by stages, advancing the blade of pipe cutter slowly. Extra force and a deep cut will cause more

distortion of pipe and therefore extra burr.

• Remove burrs from cut edges of pipes with a remover. This will avoid unevenness on the flare face which will cause gas

leak.

• Align the center of the piping and sufficiently tighten the flare nut with fingers. Finally, tighten the flare nut with torque

wrench until the wrench clicks.

• Be sure to execute heat insulation. (polyurethane form with thickness more than 15 mm)

• Except the outdoor unit which is pre-charge with refrigerant R22, the indoor unit and the refrigerant connection pipes must

be purged because the air that contain moisture remaining in the refrigerant cycle may cause malfunction to the compressor.

Additional Charge (In gram)

The refrigerant is pre-charge in the outdoor unit, but additional charge of refrigerant after vacuuming is necessary. Follow the recommendation as tabulated below.

SPECIAL PRECAUTIONS WHEN DEALING WITH R410A UNIT

R410A is a new HFC refrigerant which does not damage the ozone layer. The working pressure of this new refrigerant is

1.6 times higher than conventional refrigerant (R22), thus proper installation / servicing is essential.

• Never use refrigerant other than R410A in an air condi-

tioner which designed to operate with R410A.

• POE oil is used as lubricant for R410A compressor, which

is different from the mineral oil used for R22 compressor. During installation or servicing, extra precaution must be taken not to expose the R410A system too long to moist air. Residual POE oil in the piping and components can absorb moisture from the air.

• To prevent mischarging, the diameter of the service port

on the flare valve is different from that of R22.

SPECIAL PRECAUTIONS WHEN DEALING WITH R407C UNIT

• R407C is a zeotropic refrigerant mixture which has zero

ozone depletion potential and thus conformed to the Montreal Protocol regulation. It requires Polyol ester oil (POE) oil for its compressor's lubricant. Its refrigerant capacity and performance are about the same as the refrigerant R22.

• POE oil is used as lubricant for R407C compressor, which

is different from the mineral oil used for R22 compressor. During installation or servicing, extra precaution must be taken not to expose the R407C system too long to moist air. Residual POE oil in the piping and components can absorb moisture from the air.

• Refrigerant R407C is more easily affected by dust of mois-

ture compared with R22, make sure to temporarily cover the ends of the tubing prior to installation.

• Use tools and materials exclusively for refrigerant R410A. Tools exclusively for R410A are manifold valve, charging hose, pressure gauge, gas leak detector, flare tools, torque wrench, vacuum pump and refrigerant cylinder.

• As an R410A air conditioner incurs higher pressure than R22 units, it is essential to choose the copper pipes correctly. Never use copper pipes thinner than 0.8mm even though they are available in the market.

• If the refrigerant gas leakage occurs during installation / servicing, be sure to ventilate fully. If the refrigerant gas comes into contact with fire, a poisonous gas may occur.

• When installing or removing an air conditioner, do not allow air or moisture to remain in the refrigerant cycle.

• No additional charge of compressor oil is permitted.

• No other refrigerant other than R407C.

• Tools specifically for R407C only (must not be used for R22 or other refrigerant).

i) Manifold gauge and charging hose ii) Gas leak detector iii) Refrigerant cylinder/charging cylinder iv) Vacuum pump c/w adapter v) Flare tools vi) Refrigerant recovery machine

• Filter-dryer must be installed along the liquid line for all R407C air conditioners. This is to minimise the contamination of moisture and dirt in the refrigerant system. Filterdryer must be of molecular sieve type. For a heat-pump system, install a two-way flow filter dryer along the liquid line.

VACUUMING AND CHARGING

Vacuuming is necessary to eliminate all moisture and air from the system. The series II Outdoor Unit is provided with flare valve fittings.

Vacuuming

Before vacuuming, perform leak check for refrigeration circuit. After the system piping are properly connected, connect the flexible hoses to the correct charging nipples as shown in the diagram. Ensure that flexible hose from charging nipples are connected to the vacuum pump via standard servicing valves and pressure gauges (gauge manifold). Vacuum the air conditioner system to at least 500 microns Hg. Do not start the unit when the system is engaged in vacuuming.

Charging

Before charging, the vacuum must be held at 500 microns Hg for at least 15 minutes, then break vacuum by charging R-22 refrigerant. Operate the unit for 15 minutes and ensure the refrigerant charges is of correct by monitoring running current, gas and liquid line pressures. Suction and discharge pipe pressure should be in the region of 75 psig and 275 psig generally.

After ensuring the system is correctly charged, remove flexible hose from charging nipples and replace caps.

SPECIAL PRECAUTIONS WHEN CHARGING UNIT WITH

COPELAND SCROLL COMPRESSORS

These precautions are intended for use with Copeland Scroll compressors only with R22, R407C, R134A, R404A, R507 and R410A refrigerants but are not applied to Copeland reciprocating compressors or competitive Scroll compressors.

Scroll compressors have a very high volumetric efficiency and quickly pump a deep vacuum if there is insufficient refrigerant in the system or if refrigerant is added too slowly. Operation with low suction pressure will quickly lead to very high discharge temperatures. While this process is happening, the scrolls are not being well lubricated – scrolls depend on the oil mist in the refrigerant for lubrication. A lack of lubrication leads to high friction between the scroll flanks and tips and generates additional heat. The combination of heat of compression and heat from increased friction is concentrated in a small localized discharge area where temperatures can quickly rise to more than 300˚C. These extreme temperatures damage the Scroll spirals and the orbiting Scroll bearing. This damage can occur in less than one minute especially on larger compressors. Failure may occur in the first few hours or the damage done during field charging may show up some time later.

Other typical field charging problems include undercharging, overcharging, moisture or air in the system etc. In time each one of these problems can cause compressor failure.

Minimal equipment is required for field charging. The minimum equipment required to do a satisfactory job is:-

Set of service gauges Vacuum gauge Hoses Scales Vacuum pump Thermometer

The proper refrigerant charge should follow the volume as recommended by manufacturer and recommendation should be followed by the installer.

1. Charging procedures – Single phase compressors

Evacuate the system to 500 microns Hg. (67Pa). To reduce evacuation time, use short, large diameter hoses and connect to unrestricted service ports on the system. Quality of vacuum cannot be determined by time – a reliable vacuum gauge must be used. (etc. electronic vacuum gauge)

Turn the refrigerant cylinder upside down, purge the charging hose and charge liquid through the liquid line charging port until refrigerant no longer flows or until the correct charge has been weighed in. If additional charge is required start the system and slowly bleed liquid into the suction side until the system is full.

Copeland recommends charging liquid in a CONTROLLED manner into the suction side until the system is full. This recommendation does not hold true for reciprocating compressors where liquid charging into the suction side could cause severe damage.

Carefully monitor the suction and discharge pressures – ensure that the suction pressure does not fall below 25 psig (1.7 bar) at any time during the charging process.

! Caution

• Manifold Gauge will show cylinder pressure rather than suction pressure if the cylinder valve and Manifold valve “A” are both open.

There are many ways of charging liquid in a “controlled manner” into the suction side:-

1. Use valve A on the manifold gauge set

2. Use the valve on the refrigerant cylinder

3. Charge through a Shredder valve

4. Use a hose with a Shredder valve depressor

5. Charge into the suction side at some distance from the compressor

2. Charging procedures – Three phase compressors

The fundamental procedure is the same as for single phase models but the compressor can run in the wrong direction on starting. If this happens reverse any two phases and start again. Short term reverse rotation will not damage the compressor.

All Specter compressors (Model: ZR90 to ZR19M) have internal discharge temperature protectors which are very effective in preventing dangerously high discharge temperatures during charging. The protection module will trip and lock the compressor out for 30 minutes. It is not normally necessary to wait 30 minutes for the module to reset. When the compressor has cooled down the module can be reset by breaking the power supply to the control circuit. Very often the serviceman does not understand why the module tripped and uses a jumper wire to bypass it. He continues to charge the system and removes the jumper when charging is complete. The compressor may or may not run with the protector back in the circuit but it is certain that the compressor has been damaged and premature failure is inevitable.

NOTE

• Avoid using the short duct on which the air discharge grille can be completely closed, to prevent evaporator freezing.

• In order to prevent condensation forming, be sure that there is sufficient thermal insulation and no leakage of cool

air when installing the short duct.

• Keep the introduction of fresh air intake within 20% of total air flow. Also provide a chamber and use a booster fan.

Sealing Material

• It is possible to seal one of the four air discharge outlet. (sealing two or more air discharge outlet could cause a malfunction)

• Remove the front panel and insert the sealing material into the air discharge outlet on the indoor unit to seal the air outlet.

• The sealing material is the same length as the longer air discharge outlet. If it is desired to seal the shorter air discharge

outlet, cut the sealing material to shorten it.

• Push the sealing material in about 10 mm beyond the bottom surface of the indoor unit so that it does not touch the air

louver. Be sure not to push the sealing material in any farther than about 10 mm.

Remote Control

When there is infrared remote control operating signal, the signal receiver on indoor unit will made a <beep> for signal acceptance confirmation.
