NOTE:
5 Principal of Operation
Components in flowcharts are presented according to the following table:
6
In cooling, the low-temperature and low-pressure refrigerant gas from each indoor heat exchanger will be merged and inhaled by the compressor and then become high-temperature and high-pressure gas, which will later be discharged into outdoor heat exchangers. By exchanging heat with outdoor air, refrigerant will turn to liquid and flow to each indoor unit via Y-type branch or manifold. Pressure and temperature of the refrigerant will then be lowered by throttle elements before it flows into indoor heat exchangers. After exchanging heat with indoor air, refrigerant wil become low-temperature and low-pressure gas again and repeat the circulation so as to realize the cooling effect. In heating, 4-way valve will be energized to make refrigerant circulate in a reverse direction of cooling. Refrigerant will release heat in indoor heat exchangers (electric heating elements will also work under certain circumstance and release heat) and absorb heat in outdoor heat exchangers circularly so as to realize the heating effect.

1 Units’ Control
1.1 Schematic diagram of units’ control
(1) Interpretation on the schematic diagram
1) High pressure switch is used to identify system’s high and low pressure. When pressure is too high, the switch will break off and send a signal to main board. Main board will pass this signal to controller, where the error will be displayed, and stop unit from working.
2) High/low pressure sensor is used to test unit’s high/low pressure and send real-time data to controller, which will control each unit’s output according to the control logic.
3) Temperature sensors are used to test the tube temperature of the unit and send
data to the controller, which will control each unit’s output according to the control
logic.
