Enter four-way reversing valve with the opening of four-way reversing valve lower left side, the opening outflow of lower central is detached through vapour liquid separator 7
Afterwards, it is again introduced into compressor 1, so recycles.
When user needs to freeze to interior, refrigeration cycle starts, and the gas fluorine of high temperature and pressure is flowed from compressor 1
Go out, and is flowed into through the opening on four-way reversing valve top, the opening outflow of lower left side, then enter second through the 7th check valve 87 and change
In hot device 6, the second water circulation pipe 11 is discharged from the water inlet of the left side of the second heat exchanger 6, right side at this time, the gas fluorine of high temperature and pressure
Heat exchange is carried out with the cold water in the second water circulation pipe 11, releases in heat to water body, i.e., waste heat is discharged, high temperature and pressure
Gas fluorine be changed into the liquid fluorine of high temperature and pressure, after the 8th check valve 88, throttle valve 5 and liquid storage device 4, turn
Become the liquid fluorine of low-temp low-pressure, then flowed into First Heat Exchanger 3 through the 5th check valve 85, at this time the first water circulation pipe 10 from
Right side water inlet, the left side water outlet of First Heat Exchanger 3, the liquid fluorine of low-temp low-pressure absorb the heat in the first water circulation pipe 10
Afterwards, it is changed into the gas fluorine of low-temp low-pressure, the water temperature in the first water circulation pipe 10 reduces at this time, can freeze to interior,
The gas fluorine of low-temp low-pressure enters four-way reversing valve through the opening on the right side of the 6th check valve 86 and four-way reversing valve lower part, in lower part
The opening of centre flows out, and after gas-liquid separator separates 7, is again introduced into compressor 1, so recycles.
As alternative embodiment, changeover module 8 or three-way diverter valve or single-pole double-throw switch (SPDT) etc. are flowed to, only
The flow direction for wanting can to change refrigerant, is adjusted without the position to original other assemblies in circulation line
It is whole, to reduce cost, save raw material.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes still within the protection scope of the invention.
