Water pump 41 is closed, the first solenoid valve 1, second solenoid valve 2, the 3rd solenoid valve 3, the 4th solenoid valve 4, the first water supply pump 31 and heat
Water pump 21 is opened, and compressor 11, which is opened, drives refrigerant to be flowed in refrigerant circulation loop 10, the high temperature that compressor 11 is discharged
Refrigerant heats the water for being circulated through hot water heat exchanger 12, and the refrigerant after expansion valve 14 flows into cold-water heat exchanger
In 15, the water in the cold convection current supercooling water- to-water heat exchanger 15 of refrigerant release carries out cooling and forms chilled water, and chilled water is by first
The power of water supply pump 31 is sent into indoor heat exchanger 40 and exchanges heat with room air, so as to reduce the temperature of room air.
When low power consumption at night, accumulation of heat and cold-storage pattern are run, compressor 11 is opened at this time, and refrigerant is made to freeze
It is flowed in agent circulation loop 10, opens simultaneously 21 and first water supply pump 31 of the first solenoid valve 1, second solenoid valve 2 and heat-exchanger pump,
So that the water in regenerative apparatus 20 flows through hot water heat exchanger 12 by the Xun Huan of heat-exchanger pump 21, the high temperature discharged using compressor 11
Refrigerant carries out circulating-heating to water, and the hot water after heating is reentered in regenerative apparatus 20 and stored, followed with forming hot water
Loop back path；And the water in cold-storage device 30 flows through cold-water heat exchanger 15 by the first water supply pump 31 Xun Huan, utilizes refrigerant vapor
When discharge cold energy cycle freeze to water, the chilled water after cooling is reentered in cold-storage device 30 and stored, shape
Into freezing water-flow circuit.
When the peak times of power consumption on daytime, 30 independent cooling of cold-storage device is run, compressor 11 is closed at this time, and refrigerant follows
Loop back path 10 stops, and the 3rd solenoid valve 3, the 5th solenoid valve 5 and the second water supply pump 41 are opened, other solenoid valves and other pumps close
Close, the chilled water in cold-storage device 30 is sent by the second water supply pump 41 in indoor heat exchanger 40 through the 5th solenoid valve 5, and with interior
Air carry out heat exchange, to reduce indoor air themperature, so as to individually using the chilled water in cold-storage device 30 come pair
Room air cools down, and power consumption is low.
When the water temperature rise in cold-storage device 30 makes indoor heat exchanger 40 carry out air so as to provide compared with High cooling power
During cooling, the 5th solenoid valve 5 and the second water supply pump 41 are closed, the first solenoid valve 1, second solenoid valve 2, the 3rd solenoid valve 3,
Four solenoid valves 4 and the first water supply pump 31 are opened, and notice compressor 11, which is opened, drives refrigerant circulation, is flowed through using refrigerant cold
The cold discharged during water- to-water heat exchanger 15 cools down to the water for flowing through cold-water heat exchanger 15, and the chilled water after cooling passes through respectively
Second solenoid valve 2 and the 3rd solenoid valve 3 and enter in cold-storage device 30 and indoor heat exchanger 40, get in the cold of heat exchanger 40
Freeze water and carry out heat exchange with room air, so that indoor air themperature reduces, and enter the chilled water in cold-storage device 30
Then cold is stored.
