Mode(s)	Implement functions
		Mode one	Heating radiation floor and water heater simultaneously in winter
Mode two	Separate heat supply to radiant floor in winter
		Mode three	Supplying cold and heat to room and water heater simultaneously in summer
Mode four	Independent cooling of room in summer
		Mode five	Providing hot water only

To sum up, the utility model discloses a compressor module uses double suction double row compressor, is provided with the valve module including a plurality of three-way valves and a plurality of cross valves simultaneously, when it applied to air conditioning system, can be through the circular telegram or the outage state of each valve member in the control valve module, realize the switching of five kinds of operational modes of system, winter simultaneously to radiation floor and water heater heat supply mode, winter is to radiation floor heat supply mode alone, summer is simultaneously to the room cooling and to the water heater heat supply mode, summer is to room cooling mode alone and only provide the hot water mode, wherein: when heat is supplied to the radiant floor and the water heater simultaneously in winter, different condensation temperatures are set at the tail end of the indoor heat exchanger, and the comprehensive heating energy efficiency of the system is improved; when the cold source is used as cold source to enter the condenser of refrigerating circulation, the performance of refrigerating circulation is greatly improved.
