16 5 System Diagram 5.1 System Diagram for Cooling-and-Heating Unit Capillary 4-way valve Evaporator Condenser Cooling Gas-liquid separator Heating Compressor Switch on the power to start the unit. Low-pressure refrigerant vapor from evaporator is absorbed into the compressor, where it is compressed into high-temp. and high-pressure gas. The gas refrigerant is then diverted to condenser, where it is liquidized after heat exchange with outdoor air. After that, the liquidized refrigerant flows through capillary for decrease of temperature and pressure and then enters into evaporator, where it becomes low-temp. and low-pressure refrigerant vapor after heat exchange with indoor air to be regulated. This process is repeated in cycle to achieve the purpose of cooling. (Under heating mode, the 4-way valve will change the flow of refrigerant, so that the condenser absorbs heats and the evaporator gives out heats, thus to achieve the purpose of heating). 13
