Operation principle：, refrigeration when, in the plate type heat exchanger that underground water is pumped into outdoor unit as low-temperature receiver with water pump, and come
From the high-temperature high-pressure refrigerant steam of compressor discharge, heat exchange is carried out by stainless steel plate, complete the condensation of unit refrigeration
Process；
When heating, refrigerant vapour to releasing heat and swollen through heating power by coil exchanger in the water of hot and cold water tank
The throttling of swollen valve, is entered in plate type heat exchanger with Room-temperature low-pressure liquid condition, by stainless steel plate with absorbing in plate type heat exchanger
The heat of lower water, completes the evaporation process that unit is heated；
Coil exchanger is set in hot and cold water tank, during refrigeration, the Room-temperature low-pressure refrigerant in coil exchanger pipe
Liquid absorbs the water temperature in water tank by coil pipe wall, makes chilled water；When heating, the high temperature in coil exchanger pipe is high
Compression refrigerant steam, high temperature is released by coil pipe wall to the water in water tank, makes hot water.
Work process：(filled arrows are refrigeration, and hollow arrow is to heat), family expenses geo-source heat-pump air conditioner as shown in Figure 1
During group refrigeration, after refrigerant compresses through the refrigeration compressor 120, entered by the four-way reversing valve 110 (now no power)
Enter the plate type heat exchanger 130, heat exchange is carried out with underground water therein by stainless steel plate, the condensation heat quilt in refrigerant
Underground water is taken away, and heated underground water now is introduced into interior using pipeline uses as domestic sanitary hot water.Then
Refrigerant, as Room-temperature low-pressure refrigerant liquid, through stop valve 160, is entered by the filter 140, heating power expansion valve 150
In coil exchanger 220 in hot and cold water tank 20, the water temperature in attemperater 210 is absorbed by coil pipe wall, make cold
Freeze water, refrigerant liquid absorbs the gas as low-temp low-pressure after heat, returns to compressor, complete the compression circulation of refrigerant.
When family expenses geo-source heat-pump air conditioner group is heated, after refrigerant compresses through the refrigeration compressor 120, by described four
The commutation of logical reversal valve 110 (being now powered), into the coil exchanger 220 in the hot and cold water tank 20, refrigerant vapour
Heat is released to the water in attemperater 210 by coil pipe wall, hot water is made, through heating power after refrigerant gas releasing heat
Expansion valve 150 is throttled, and as Room-temperature low-pressure liquid, enters back into the plate type heat exchanger 130, and heat exchange is carried out with underground water, into
For low temperature low pressure gas return to compressor, the compression circulation of refrigerant is completed.
Equally, the hot water in hot and cold water tank 20, into the air conditioning terminal in exchanged heat with room air, in blower fan
Under effect, heating is sent out to respective room.
Embodiment：Using underground water characteristic cool in summer and warm in winter, outdoor unit is pumped into using underground water as Cooling and Heat Source with water pump
In plate type heat exchanger.When unit freezes, heat exchange, refrigerant are carried out with the high-temperature high-pressure refrigerant steam discharged from compressor
Turn into normal temperature high voltage liquid after cooled, the coiled entered in cold (heat) water tank by stop valve after capillary-compensated is exchanged heat
In device, Room-temperature low-pressure refrigerant liquid carries out heat exchange by the water of copper pipe wall and hot and cold water tank, drops the water temperature of hot and cold water tank
Low to 7 DEG C, chilled water is then sent into by indoor each air conditioning terminal by water pump, water pipe and pipe joint and produces cold air；Unit is heated
When, the high-temperature high-pressure refrigerant steam of compressor discharge enters in coil exchanger, to hot and cold water tank's through four-way reversing valve
Heat is released in water, water temperature rises to 45 DEG C, hot water is then sent into by indoor each air conditioning terminal by water pump and produces heating.Refrigeration
Through capillary-compensated after agent releasing heat, entered in plate type heat exchanger with Room-temperature low-pressure liquid condition, absorb the heat of underground water
And low temperature low pressure gas are flashed to, it is compressed circulation into compressor.
Embodiment provided above is better embodiment of the invention, only for the convenient explanation present invention, not to this hair
It is bright to make any formal limitation, any those of ordinary skill in the art, if putting forward skill the present invention is not departed from
In the range of art feature, using the Equivalent embodiments for locally being changed done by disclosed technology contents or modify, and
