The course of work of the all-in-one machine is described below with reference to table 1：
Table 1
One, from refrigeration unit recovering liquid refrigerant
Gaseous refrigerant enters 7 (this of water condenser through gaseous state mouth valve 9 and storage tank side valve door 13 from refrigerant storage tank 8
When water supply pipe 15 close), by the valve 3 33 of four-way reversing valve, into device for drying and filtering 4, then through compressor 5 compress into
Enter oil eliminator 6, then using the valve of four-way reversing valve 1, unit side valve door 14, condenser gaseous state mouth valve 2, which enters, to be made
Cold train condenser 1.Since gaseous refrigerant constantly enters in refrigeration unit condenser 1 from refrigerant storage tank 8, refrigerant
Pressure reduction in holding vessel 8, the pressure rise of refrigeration unit, since there are pressure difference, liquid refrigerant is steamed from refrigeration unit
It sends out device 11 to enter in refrigerant storage tank 8 by evaporator liquid mouth valve 12 and liquid mouth valve 10, to realize from refrigeration
Unit recovering liquid refrigerant.
Two, gaseous refrigerant is recycled from refrigeration unit
Gaseous refrigerant passes through condenser gaseous state mouth valve 2, unit side valve door 14 from refrigeration unit condenser 1, by four
Then the valve 2 32 of logical reversal valve enters oil eliminator 6 through the compression of compressor 5, then using four into device for drying and filtering 4
The valve 4 34 of logical reversal valve, into water condenser 7, at this point, water supply pipe 15 is opened, gaseous refrigerant is condensed into liquid, passes through
Storage tank side valve door 13, gaseous state mouth valve 9, returns in refrigerant storage tank 8, recycles gaseous refrigerant to realize from refrigeration unit
Agent.When gaseous refrigerant is discharged, pressure reduction in refrigeration unit, liquid refrigerant can constantly gasify, and absorb heat, in order to
Refrigeration unit freezing damage is prevented, needs to open evaporator water pump and condenser water pump, the cooling capacity of generation is taken away, protection refrigeration
Unit.
Three, oil and impurity are separated from refrigerant
In above process, the liquid refrigerant recycled from refrigeration unit evaporator passes through 12 He of evaporator liquid mouth valve
Liquid mouth valve 10 enters in refrigerant storage tank 8, and refrigerant contains oil and impurity, needs to purify it.At this point, passing through
Heater 16 heats refrigerant storage tank 8, and liquid refrigerant becomes gaseous state, from gaseous state mouth valve 9, through storage tank side valve door 13 into
Enter in water condenser 7 (water supply pipe 15 is closed at this time), then the valve 3 33 through four-way reversing valve, dry into device for drying and filtering 4
It is dry, using compressor compresses, into oil removing and impurity is gone in oil eliminator, the then valve 1 through four-way reversing valve, unit
Side valve door 14, condenser gaseous state mouth valve 2 return in refrigeration unit condenser, so that it is oily and miscellaneous to realize the separation from refrigerant
Matter.When gaseous refrigerant is constantly delivered in refrigeration unit, pressure rise in refrigeration unit, gaseous refrigerant can continuous liquid
Change, discharge heat and pressure rise, refrigeration unit crosses cause thermal damage and superpressure damage in order to prevent, need to open evaporator water pump or
Condenser water pump takes away the heat of generation, protects refrigeration unit.
Four, refrigerant is filled to refrigeration unit
The first step, exhaust：During this, compressor 5 is closed, and utilizes the pressure in refrigeration unit and refrigerant storage tank
Difference, gaseous refrigerant is directly from refrigeration unit condenser 1, and by condenser gaseous state mouth valve 2, unit side valve door 14 passes through
The valve 1 and valve 4 34 or valve 2 32 and valve 3 33 of four-way reversing valve, into water condenser 7, then through storage tank side valve door
13 and gaseous state mouth valve 9 enter refrigerant storage tank 8 in, play the role of balance pressure difference.
Second step, liquid filling：Compressor 5 is opened, gaseous refrigerant is from refrigeration unit condenser 1, by condenser
Gaseous state mouth valve 2, unit side valve door 14, by the valve 2 32 of four-way reversing valve, into device for drying and filtering 4, then through compressor
Compression, by oil eliminator 6, using the valve 4 34 of four-way reversing valve, water condenser 7 (water supply pipe 15 is closed at this time), storage
Tank side valve door 13 and gaseous state mouth valve 9 enter in refrigerant storage tank 8.Since gaseous refrigerant is constantly condensed from refrigeration unit
Device 1 enters in refrigerant storage tank 8, the pressure reduction of refrigeration unit, the pressure rise of refrigerant storage tank 8, due to existing
Pressure difference, liquid refrigerant can pass through liquid mouth valve 10 from refrigerant storage tank 8, and evaporator liquid mouth valve 12 enters system
In cold group evaporator 11, to realize the filling of liquid refrigerant.
Third step, gaseous state filling：Compressor 5 is opened, gaseous refrigerant is from refrigerant storage tank 8 through gaseous state mouth valve 9, storage
Tank side valve door 13, into water condenser 7, then the valve 3 33 through four-way reversing valve, compresses into compressor 5, then through oil
Separator 6, the valve 1 of four-way reversing valve, unit side valve door 14, condenser gaseous state mouth valve 2 enter refrigeration unit condenser 1
In, when gaseous refrigerant is constantly delivered in refrigeration unit, pressure rise in refrigeration unit, gaseous refrigerant can continuous liquid
Change, discharge heat and pressure rise, refrigeration unit crosses cause thermal damage and superpressure damage in order to prevent, need to open evaporator water pump and
Condenser water pump takes away the heat of generation, protects refrigeration unit.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest scope consistent with features of novelty.
