Gas-liquid separator 14, refrigeration branch and heat branch road；Gas-liquid separator 14 outlet connects compressor 1 and enters
Mouthful, compressor 1 outlet and gas-liquid separator 14 import connect First Heat Exchanger 4 by four-way change-over valve 3
With the second heat exchanger 13.
Refrigeration branch one end connects First Heat Exchanger 4, and the other end connects the second heat exchanger 13, refrigeration branch
It is sequentially connected with the first check valve 6, fluid reservoir 8 from First Heat Exchanger 4 to the second heat exchanger 13, has filtered
Device the 9, second check valve 10 and the first expansion valve 11.
Heating branch road one end and connect First Heat Exchanger 4, the other end connects the second heat exchanger 13, heats branch road
It is sequentially connected with the 3rd check valve 12, fluid reservoir 8 from the second heat exchanger 13 to First Heat Exchanger 4, has filtered
Device the 9, the 4th check valve 7 and the second expansion valve 5.
The refrigeration branch that this enforcement uses shares fluid reservoir 8 and filter 9 with heating branch road, it is noted that
Refrigeration branch can also be used alone respective fluid reservoir and filter with heating branch road.
Fluid reservoir 8 import connects the first check valve 6 and the 3rd check valve 12, fluid reservoir 8 by tee T
Outlet connects filter 9 import, and filter 9 exports and connects the second check valve 10 and the 4th by tee T
Check valve 7.
First Heat Exchanger 4 is air-cooled heat exchanger, and four-way change-over valve 3 is electromagnetic type four-way change-over valve.The
One heat exchanger 4 is outdoor heat exchanger, and the second heat exchanger 13 is indoor heat exchanger.
During refrigeration, under the effect of four-way change-over valve 3, coolant changes through four-way through compressor 1 outlet stream
Enter First Heat Exchanger 4 to valve 3, take heat to outdoor by the blower fan of First Heat Exchanger 4；Warp again
Cross the first check valve 6 and enter fluid reservoir 8, in fluid reservoir 8, regulate flow maintain the balance of system；Again
The first expansion valve 11 is entered, by the cryogenic gas of generation second through filter the 9, second check valve 10
In heat exchanger 13 after heat exchange, enter gas-liquid separator 14 by four-way change-over valve 3, the most again by gas
It is internal that state returns to compressor 1.
When heating, under the effect of four-way change-over valve 3, coolant exports through compressor 1 and commutates through four-way
Valve 3 enters the second heat exchanger 13, after heat exchange, sequentially passes through the 3rd check valve 12, fluid reservoir 8, mistake
Filter the 9, the 4th check valve the 7, second expansion valve 5, First Heat Exchanger 4, commutate through four-way the most again
Valve 3 returns to gas-liquid separator 14, gaseous state return to compressor 1 internal.Principle is contrary with during refrigeration, this
Place repeats no more.
As it is shown on figure 3, the second heat exchanger 13 is water-cooled heat exchanger, present invention additionally comprises the first water circulation
Loop, the first water-flow circuit includes the second heat exchanger the 13, first water pump 131 and the 4th heat exchange of concatenation
Device 132, i.e. the heat exchange agent discrepancy of the second heat exchanger 13 or entrance be sequentially connected with the first water pump 131 with
4th heat exchanger 132, the 4th heat exchanger 132 connects the second heat exchanger 13 and is not connected with the first water pump 131

The number of the 4th heat exchanger 132 is multiple, and the present embodiment is as a example by 3.3 the 4th heat exchangers
Connect with second heat exchanger the 13, first water pump 131 again after 132 parallel connections and form the first water-flow circuit.
The 5th check valve 133 is had additionally, be connected between the first water pump 131 with the second heat exchanger 13.
The present embodiment also include water supply tank 134, the outlet of water supply tank 134 connect the first water pump 131 with
On pipeline between 4th heat exchanger 132.
Heat exchange agent in 4th heat exchanger 132 can be water, and current provide pressure by the first water pump 131,
Flow through the second heat exchanger 13, after the coolant sufficient heat exchange of flowing in the second heat exchanger 13, by cold
Or heat brings the 4th heat exchanger 132 into, the 4th heat exchanger 132 is the air cooling heat exchanger being satisfied with indoor, logical
Cross blower fan cold or heat band is indoor, then pass back into the first water pump 131.First water pump 131 and second
Heat exchanger 13 is provided with the 5th check valve 133, improves the stability of device.First water pump 131 changes with the 4th
Be connected with the water inlet of water supply tank 134 on pipeline between hot device 132, it is provided that supplement inner loop water or
The function of displacement inner loop water.
Additionally, the second heat exchanger 13 can also be air-cooled heat exchanger, directly carry out heat hand over room air
Change.
As shown in Figure 2,4, the 3rd heat exchanger 2 is water-cooled heat exchanger, and is located at compressor 1 and four-way
Between reversal valve 3, present invention additionally comprises the second water-flow circuit, the second water-flow circuit includes concatenating shape
Become the 3rd heat exchanger 2 of closed-loop path, water tank 15 and the second water pump 16, i.e. the 3rd heat exchanger 2 is provided with
First water inlet 21 and the first outlet 22, water tank 15 is provided with the second water inlet 151 and the second outlet
152, the first water inlet 21 connects the second outlet 152, and the first outlet 22 connects the second water inlet 151,
Second water pump 16 is connected between the first water inlet 21 and the second outlet 152 or is connected to first go out
On pipeline between the mouth of a river 22 and the second water inlet 151.
3rd heat exchanger 2, water tank the 15, second water pump 16 are connected into loop, the second water pump 16 provide
Internal water is formed loop between the 3rd heat exchanger 2 and water tank 15 by pressure.In the case of air conditioner refrigerating,
Start the second water pump 16 and the first water pump 131 or blower fan of the second heat exchanger 13, can be same freeze
Shi Huishou heat, also mitigates the load of First Heat Exchanger 4 simultaneously.In the case of air-conditioning heating, can
Water heating is preferential, after hot water temperature arrives, closes the second water pump 16, opens the of the second heat exchanger 13
One water pump 131 or blower fan；Can also indoor heating preferential, first open the first water pump of the second heat exchanger 13
131 or blower fan, indoor temperature is then turned on the second water pump 16 after arriving the temperature needed.
The present invention can by flush bonding processor regulate the first water pump 131 of the second heat exchanger 13 or blower fan,
The duty of the condensation fan of the second water pump 16 and the second heat exchanger 4, it is achieved heat, freeze, make
Cold+hot water, heat+hot water and independent heating water, it is achieved that the function of a tractor serves several purposes.
The above is only the optimal way of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, it is also possible to make some similar deformation and change
Enter, within these also should be regarded as protection scope of the present invention.
