It makes a heating operation by bypassing the hot gas of high temperature and pressure at the
main cooling operation.
Prevent pressure drop through expansion valve at cooling mode.
It prevents the short refrigerant of cooling side indoor unit by jetting the gas of high pressure into the
liquid pipe for making a resistance in pipe collecting refrigerant to the outdoor unit.
Prevent pressure drop through MCU EEV at heating mode.
It distributes the refrigerant to the outdoor unit and cooling side indoor unit at the main
heating operation.
It makes the operation mode of indoor unit to ON at the cooling operation.
It makes the operation mode of indoor unit to ON at the heating operation.
It is installed at the side of gas of low pressure for error judgment at the cooling operation of
outdoor unit. And it checks the error of 4-Way V/V at the heating or main heating operation.
It prevents the congestion of refrigerant or the freezing of cooling side indoor unit.
