Notes:

a. The rated cooling capacity data is measured under the following work condition: Indoor Temperature is 27ć

DB, 19ćWB. Outdoor Temperature is 35ćDB. The rated heating capacity data is measured under the following

work condition: Indoor Temperature is 20ćDB. Outdoor Temperature is 7ćDB, 6ćWB.

b. The data will change with the change of products. Refer to those parameters listed on nameplate.

c. Noise was tested in semi-silenced room, so the actual noise value will be a little higher for change of ambient.

4. Refrigerant System Diagram

Schematic Diagram of Super Free Match Series Inverter Heat Pump Multi System

The units start to work once the power is switched on.

During the cooling operation, the low temperature, low pressure refrigerant gas from the heat exchanger of

each indoor unit gets together and then is taken into the compressor to be compressed into high temperature, high

pressure gas, which will soon go to the heat exchanger of the outdoor unit to exchange heat with the outdoor air

and then is turned into refrigerant liquid. After passing through the BU module, the temperature and pressure of

the refrigerant liquid will further decrease and then go the main valve. After that, it will be divided and go to the

heat exchanger of each indoor unit to exchange heat with the air which needs to be conditioned. Consequently, the

refrigerant liquid become low temperature, low pressure refrigerant gas again. Such a refrigeration cycle goes

round and round to achieve the desired refrigeration purpose.

During the heating operation, the four-way valve is involved to make the refrigeration cycle run reversely.

The refrigerant radiates heat in the heat exchanger of the indoor unit (so do the electric heating devices) and

absorb heat in the heat exchanger of the outdoor unit for a heat pump heating cycle so as to achieve the desired

heating purpose.
