(1) Temperature sensor (EIS, Evaporator Inlet Sensor)

The means to measure the refrigerant temperature at the inlet of heat exchanger which is used as the data

for control of electronic expansion valve.

(2) Temperature sensor (EOS, Evaporator Outlet Sensor)

The means to measure the refrigerant temperature at the outlet of heat exchanger which is used as the data

for control of electronic expansion valve.

(3) Temperature sensor (IATS, Indoor Air Temperature Sensor)

The means to measure the indoor temperature which is used as the data for operation method of indoor

and outdoor unit.

(4) Electronic expansion valve (EEV) kit

For the MICOM of indoor unit to control the opening of electronic expansion valve by comparing the

temperatures of inlet and outlet of heat exchanger for the optimum control of refrigerant flow.

(5) Strainer

It has the structure in which the filter is inserted and it removes the foreign material from the piping inside.
