暖房運転を行なうことができることになる。Since it is equipped with an auxiliary refrigerant cycle in which the auxiliary heat source side pressure reducing device and the auxiliary indoor heat exchanger installed in the auxiliary indoor unit are connected in a ring, the auxiliary refrigerant cycle can be used regardless of the operation of the heat source side refrigerant cycle and the user side refrigerant cycle. This means that cooling or heating operation can be performed.
従って室外ユニットが１台で各室内ユニットが冷房運転
又は暖房運転の選択がそれぞれ自由にできることになシ
、中間期等室内負荷によって冷房運転をする必要のある
室内と、暖房運転をする必要のある室内が混在する場合
に、室外ユニットが１台の簡単な構成で同時に運転でき
る効果がある。Therefore, with only one outdoor unit, each indoor unit can freely choose between cooling operation or heating operation. When indoors are mixed, there is an effect that the outdoor unit can be operated at the same time with a simple configuration of one unit.
