The course of work of the all-in-one machine is described with reference to table 1：
Table 1
First, from refrigeration unit recovering liquid refrigerant
Gaseous refrigerant enters 7 (this of water condenser from refrigerant storage tank 8 through gaseous state mouth valve 9 and storage tank side valve door 13
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 is constantly entered from refrigerant storage tank 8 in refrigeration unit condenser 1, refrigerant
Pressure reduction in holding vessel 8, the pressure rise of refrigeration unit, since there are pressure differential, liquid refrigerant is steamed from refrigeration unit
It sends out device 11 by evaporator liquid mouth valve 12 and liquid mouth valve 10 to enter in refrigerant storage tank 8, so as to fulfill from refrigeration
Unit recovering liquid refrigerant.
2nd, 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
The valve 2 32 of logical reversal valve into device for drying and filtering 4, then enters oil eliminator 6, then using four through the compression of compressor 5
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, and gaseous refrigerant is recycled so as to fulfill 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 cold of generation is taken away, protection refrigeration
Unit.
3rd, oil and impurity are detached 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, pass 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, oil removing and impurity are gone into oil eliminator, then the valve 1 through four-way reversing valve, unit
Side valve door 14, condenser gaseous state mouth valve 2 are returned in refrigeration unit condenser, it is achieved thereby that being detached from refrigerant oily and miscellaneous
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.
4th, 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 in refrigerant storage tank 8, play the role of balancing pressure differential.
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 is entered in refrigerant storage tank 8, the pressure reduction of refrigeration unit, the pressure rise of refrigerant storage tank 8, due to existing
Pressure differential, liquid refrigerant can be from refrigerant storage tanks 8 by liquid mouth valve 10, and evaporator liquid mouth valve 12 enters system
In cold group evaporator 11, so as to fulfill the filling of liquid refrigerant.
Third walks, 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.
