Water heat exchange inside water tank：On the one hand the water inside heat-exchanging water tank is heated, and the hot water after heating is directly carried for users to use；Another
Aspect, after heat exchange, the gaseous refrigerant of High Temperature High Pressure is condensed into the liquid refrigerant of cryogenic high pressure, flows out indoor fluorine water and changes
After hot device, throttle through choke valve, enter evaporation in outdoor finned heat exchanger, air is forced to drive by blower fan, flows through outdoor
Finned heat exchanger, cold-producing medium carry out forced heat-exchanging with air, and cold-producing medium flashes to the gas of low-temp low-pressure, enters compressor, follows
Water heating purpose is reached after ring compression, institute's water heating can be used for air-conditioning heating.The major defect of this air source heat pump is：
It is only used for heating, it is impossible to for freezing.
Content of the invention
For the deficiencies in the prior art, a kind of energy realization of proposition is heated the present invention, the cold and hot linkage air source of linkage of freezing
Heat pump.
The present invention is achieved through the following technical solutions technical goal.

Device；The outdoor finned heat exchanger, choke valve, indoor fluorine water- to-water heat exchanger are connected by pipeline；The blower fan is disposed in the outdoor wing
The side of piece heat exchanger；Which thes improvement is that：Set between the compressor and outdoor finned heat exchanger, indoor fluorine water- to-water heat exchanger
There is cross valve, it is possible to achieve two kinds of connection status：A kind of connection status be compressor outlet through cross valve first passage with
Outdoor finned heat exchanger connection, compressor inlet are connected with indoor fluorine water- to-water heat exchanger through the second channel of cross valve；Another kind of
Connection status is compressor outlet to be connected with indoor fluorine water- to-water heat exchanger through the third channel of cross valve, and compressor inlet is through four
The fourth lane of port valve is connected with outdoor finned heat exchanger.
In said structure, in the compressor outlet and the pipeline of cross valve, fixed high-voltage switch is provided with.
In said structure, in the compressor inlet and the pipeline of cross valve, fixed low tension switch is provided with.
When using, compressor outlet is connected with outdoor finned heat exchanger the present invention through the first passage of cross valve, is pressed
The import of contracting machine is connected with indoor fluorine water- to-water heat exchanger through the second channel of cross valve, under this connection status, from compressor compresses
High-temperature high-pressure refrigerant gas out enters evaporation in outdoor finned heat exchanger, and air is forced to drive by blower fan, flows through room
Outer finned heat exchanger, cold-producing medium carry out forced heat-exchanging with air, and the gaseous refrigerant of High Temperature High Pressure is condensed into the liquid of cryogenic high pressure
State cold-producing medium, after flowing out outdoor finned heat exchanger, throttles through choke valve, gets in fluorine water- to-water heat exchanger, by indoor fluorine water
The heat exchange metal tube of heat exchanger is exchanged heat with the water inside heat-exchanging water tank：Water inside one side cooling heat transferring water tank, after cooling
Water is directly used in refrigeration；On the other hand, after heat exchange, cold-producing medium flashes to the gas of low-temp low-pressure, enters compressor.This
Connection status is used for freezing.
When using, compressor outlet is connected with indoor fluorine water- to-water heat exchanger the present invention through the third channel of cross valve, is pressed
The import of contracting machine is connected with outdoor finned heat exchanger through the fourth lane of cross valve, under this connection status, from compressor compresses
High-temperature high-pressure refrigerant gas out gets in fluorine water- to-water heat exchanger, the heat exchange metal tube by indoor fluorine water- to-water heat exchanger with change
Water heat exchange inside boiler：On the one hand the water inside heat-exchanging water tank is heated, and the hot water after heating is directly carried for users to use；Separately
On the one hand, after heat exchange, the gaseous refrigerant of High Temperature High Pressure is condensed into the liquid refrigerant of cryogenic high pressure, flows out indoor fluorine water
After heat exchanger, throttle through choke valve, enter evaporation in outdoor finned heat exchanger, air is forced to drive by blower fan, flows through room
Outer finned heat exchanger, cold-producing medium carry out forced heat-exchanging with air, and cold-producing medium flashes to the gas of low-temp low-pressure, enters compressor.
This connection status is used for heating.
The present invention compared with prior art, has the positive effect that：
1. cross valve is provided between compressor and outdoor finned heat exchanger, indoor fluorine water- to-water heat exchanger, it is possible to achieve two kinds of connection shapes
State：A kind of connection status is that compressor outlet is connected with outdoor finned heat exchanger through the first passage of cross valve, and compressor enters
Mouth is connected with indoor fluorine water- to-water heat exchanger through the second channel of cross valve, under this connection status, it is possible to achieve refrigeration；Another kind of
