Beschreibung
Zusammenfassung:	In order to perform a heating operation with the correct quantity of coolant at all times by retaining an approximately fixed quantity of coolant in a main condenser during the initial stage of a heating operation in an air conditioning system, a first valve is opened and, at the same time, a second valve is closed before executing the heating operation to run the cooling/heating cycle as a cooling cycle for a specific length of time. Then, after opening a bypass passage by opening the second valve, the first valve is closed to close off the passage leading to the main condenser to start the heating cycle. As a result, a fixed quantity of coolant can always be retained within the main condenser, realizing the operation of a heating cycle with a correct coolant quantity.
