1.4 Main Components Of Indoor Unit
The indoor unit of the CRV+ air cooled AC unit consists of DC brushless compressor, evaporator, electronic
expansion valve, electrode humidifier, EC fan, electric heater, sight glass, filter dryer, micro-processing controller and
so on.
Compressor
Adopt a DC brushless scroll compressor. It features low vibration, low noise and high reliability.
Evaporator
Adopt a fin-tube heat exchanger with high efficiency. The distributor is designed and verified according to individual
model to ensure that the refrigerant is distributed evenly in each loop, improving the efficiency of the heat exchanger
to a great extent.
Electronic expansion valve
Adopt an electronic expansion valve. It collects temperature and pressure signals at the same time to accurately
regulate the refrigerant flow.
Electrode humidifier
Electrode humidifier adopts a simple structure form with large humidifying volume and high efficiency. It is easy
disassembly and maintenance.
Fan
Adopt an EC fan. It features high efficiency, energy saving, space saving and low noise.
Electric heater
Adopt a PTC heater. It features quick heating, even quantity of heat, operation safety and reliability.
Sight glass
Sight glass is used to observe the refrigerant state and the moisture level content of the system. If the moisture
content level exceeds the standard level, the color of the sight glass indicator will change.
