Page 10: Piping Diagram
PRODUCT 5 PIPING DIAGRAM Schematic Diagram of Multisplit Inverter Heat Pump Schematic Diagram of Multisplit Inverter Heat Pump The outdoor and indoor 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. - Page 11 CONTROL CONTROL...
