Notes:
a. The rated cooling capacity data is measured under the following work condition: Indoor Temperature is 27℃
DB, 19℃WB. Outdoor Temperature is 35℃DB. The rated heating capacity data is measured under the following
work condition: Indoor Temperature is 20℃DB. Outdoor Temperature is 7℃DB, 6℃WB.
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.

Notes:
a. The rated cooling capacity data is measured under the following work condition: Indoor Temperature is 27℃
DB, 19℃WB. Outdoor Temperature is 35℃DB. The rated heating capacity data is measured under the following
work condition: Indoor Temperature is 20℃DB. Outdoor Temperature is 7℃DB, 6℃WB.
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.

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.
