2.1 Working Principle and Special Functions for Cooling

2.2 Working Principle and Special Functions for Heating (Heat Pump Model Only)

Principle:

Air conditioner absorbs heat in the room and transmit to outdoor and discharged, so that indoor ambient temperature decreased. It's cooling capacity will decrease by the increase of outdoor ambient temperature.

Anti-freezing Function:

If the units is running in COOL mode and in low temperature, there will be frost formed on the heat exchanger, when indoor heat exchanger temperature decreased below 0 C, the indoor unit micro-computer will stop compressor running and protect the unit.

Principle:

1. Air conditioner absorbs heat from the outdoor and transmit to indoor and evaporated, so that indoor temperature increased. Its heating capacity will decrease by the decrease of outdoor ambient temperature.

2. If outdoor temperature got lower, please operate with

other heating ventilating equipments.

Defrosting:

1. When outdoor temperature is low but high humidity, after a

long while running, frost will form on outdoor unit, that will effect the heating effect. At this time, the auto defrosting function will act, and the heat running will stop for 8-10 minutes.

2. During the auto defrosting function, both the fan motors of indoor unit and outdoor unit will stop operate.

3. During the defrosting function, the indoor indicator flashes and the outdoor unit may emit vapor. This is due to the defrosting, it is not malfunction.

4. After defrosting finished, the heating will recover

automatically.

Cold Draft Prevention:

In "HEAT" mode, the indoor blower will no act at the following 3 status, while the heat exchanger haven't achieve the certain temperature. This is to prevent cool air blowing. (Within 2 minutes).

1. Heating starts.

2. After auto defrosting finished.

3. Heating under low ambient temperature.

Gentle Breeze

In the following situation, the indoor unit may blow gentle

breeze, and the guide louver rotate to a certain position:

1. In “Heat” mode, the unit turned on, the compressor does not arrive the starting condition

2. In “Heat” mode, the temperature arrive at the setting value and the compressor stop running about 1min.

10.2 Refrigerant Tubing

10.2.1 Use of The Flaring Method

Many of the conventional split system air conditioners employ the flaring method to connect refrigerant tubes which run between indoor and outdoor units. In this method, the copper tubes are flared at each end and connected with flares nuts.

10.2.2 Flaring Procedure With A Flare Tool

•

Cut the copper tube to the required length with a tube cutter. It is recommended to cut approx. 30 - 50 cm longer than the tubing length you estimate.

•

Remove burrs at the end of the copper tube with a reamer or file. This procedure is important and should be done carefully to make a good flare. (Fig.25)

NOTE

When reaming, hold the tube end downward and be sure that no copper scraps fall into the tube. (Fig.26)

Before

Deburring

After

•

Remove the flare nut from the unit and be sure to mount it on the copper tube.

•

Make a flare at the end of copper tube with a flare tool.* (Fig.27) (*Use "GRID" or equivalent.)

NOTE

10.2.3 Caution Before Connecting Tubes Tightly

•

Be sure to apply a sealing cap or water proof tape to prevent dust or water from getting into the tubes before they are used.

•

Be sure to apply refrigerant lubricant to the matching surfaces of the flare and union before connecting them together. This is effective for reducing gas leaks. (Fig.28)

•

For proper connection, align the union tube and flare tube straight with each other, then screw in the flare nut lightly at first to obtain a smooth match. (Fig.29)

A good flare should have the following charactcteristics:

- inside surface is glossy and smooth.

- edge is smooth.

- tapered sides are of uniform length.

IMPORTANT

To prevent heat loss and wet floors due to dripping of condensation, both tubes must be well insulated with a proper insulation material. The thickness of the insulation should be a min. 8 mm. (Fig. 31, 32)

CAUTION

After a tube has been insulated, never try to bend it into a narrow curve, as this may cause to break or crack.

10.2.6 Taping the Tubes

•

At this time, the 2 refrigerant tubes (and electrical wire if codes permit) should be taped together with armoring tape. The drain hose may also be taped together as 1 bundle with the tubing.

•

Wrap the armoring tape from the bottom of the outdoor to the top of tubing where it enters the wall. As you wrap the tubing, overlap half of each previous tape turn. (Fig. 33)

Clamp tubing bundle to wall, using 1 clamp

• approx. every 120cm.

NOTE

Do not wind the armoring tape too tightly, since this will decrease the heat insulation effect. Also, be sure the condensation drain hose splits away from the bundle and drips clear of the unit and the tubing.

10.2.7 Finish the Installation

After finishing insulating and taping over the tubing, use sealing putty to seal off the hole in the wall to prevent rain and draft from entering. (Fig. 34) shows refrigerant tubing taped separately from the drain hose.

10.3 Air Purging

Air and moisture remaining in the refrigerant system have undersirable effects as indicated below. Therefore, they must be purged completely.

• Pressure in the system rises

• Operating current rises

• Cooling (or heating) efficiency drops

• Moisture in the air may freeze and block capillary tubing.

• Water may lead to corrosion of parts in the refrigerant system.

AIR PURGING WITH A VACUUM PUMP (FOR TEST RUN)

1. Check that each tube (both narrow and wide tubes) between the indoor and outdoor units have been properly connected and all wiring for the test run has been completed. Noted that both narrow and wide tube service valves on the outdoor unit are kept closed at this stage.

Indoor unit

Outdoor unit

Manifold valve

2. Using a adjustable wrench or box wrench, remove the valve caps from the service on both narrow and wide tubes.

3. Connect a vacuum pump and a manifold valve (with pressure gauges) to the service port on the wide tube service valve. (Fig.35)

CAUTION

Be sure to use a manifold valve for air purging. If it is not available, use a stop valve for this pupose. The "Hi" knob of the manifold valve must always be kept closed.

4. With the "Lo" knob of the manifold valve open, run the vacuum pump. The operation time for the vacuum pump varies with tubing length and the capacity of the pump. The following table shows the amount of time for evacuation:
