Abstract

PURPOSE: To prevent a coolant from flowing backward at the time of starting the air conditioner by a method wherein a change-over valve is provided in an inlet side pipe passage leading to a coolant heating coil and the valve is opened at the time of starting the air conditioner utilizing a natural circulation type heating cycle between the coolant heating coil and an indoor coil.
CONSTITUTION: The air conditioner comprises an outdoor unit 1 and an indoor unit 2. The outdoor unit 1 is formed of a compressor 3, a condenser 4, a pressure reducing mechanism 5, a coolant adjuster 6, a drier filter 7, a heating means 8 and the coolant heating coil 9 which are connected to one another by means of pipes. On the other hand, the indoor unit 2 is formed of the indoor coil 10 and an indoor fan. In this case, the outdoor unit 1 includes a change-over valve 15 which is provided in a liquid pipe connected to a pipe end 9b on the lower side of the coolant heating coil 9 which end 9b becomes itself an input side of the air conditioner at the time of heating operation. The change-over valve is controled such that it is opened somewhat later than the initiation of operation of the heating means 8 at the time of heating operation while it is closed at the time of cooling operation.
