QSPEVDU 12 : http://splitoff.ru/tehn-doc.html Free Match Service Manual 5 PIPING DIAGRAM Schematic Diagram of Free Match Series Inverter Heat Pump Multi VRF System M Schematic Diagram of Free Match Series Inverter Heat Pump Multi VRF System 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. After passing through the throttling device, 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. 13 : http://splitoff.ru/tehn-doc.html QSPEVDU Free Match Service Manual INSTALLATION 32 : http://splitoff.ru/tehn-doc.html Free Match Service Manual INSTALLATION 1 PRECAUTIONS FOR INSTALLATION 1.1 Precautions for Installation Before installation, please ensure if the installing site, power ratings, possible operating range (pipe distance, height difference between indoor and outdoor unit, power voltage) and installing space are correct and suitable. The outdoor unit is general to all models according to its power. ƹ To ensure correct installation, please make sure to read the Safety Considerations thoroughly before starting the installation works.
