Beschreibung
Zusammenfassung:	A refrigeration cycle including a compressor (11), an indoor heat exchanger (12), an expansion (14,21), an outdoor heat exchanger (15) and a six-way change-over valve (115) having a refrigerant passage through which refrigerant flows in a refrigerant circuit comprising the compressor (11), the indoor heat exchanger (12), the expansion (14,21) and the outdoor heat exchanger (15), wherein the six-way change-over valve (115) serves to selectively switch the refrigerant passage so that the refrigerant passing in the indoor and outdoor heat exchangers (12,15) flows in the same direction at any time when the refrigerant cycle is switched to a cooling operation cycle and to a heating operation cycle.
