Abstract
The utility model discloses a kind of refrigeration system, the gas-liquid separator that comprises evaporimeter, is connected with the gas outlet of evaporimeter, the liquid outlet of described gas-liquid separator is connected with the inlet of evaporimeter by circulating pump, on the pipeline between described circulating pump and the inlet of evaporimeter, is also provided with check valve.The utility model has the advantages that: evaporimeter does not need overheated heat exchange, and can ensure that hydraulic compression does not appear in compressor, utilize the gas-liquid separator of compressor air suction mouth, liquid refrigerant is separated, the refrigerant liquid being separated is sent to devaporation in evaporimeter again by circulating pump system, heat exchange property by native system finisher will be largely increased, and gas-liquid separator is very little to the pressure reduction of evaporator, so circulating pump only needs very little power just refrigerant liquid can be brought back to evaporimeter, it is lower that system realizes cost.
Description
Technical field
The utility model relates to a kind of refrigeration system.
Background technology
In refrigeration system, in order to ensure that compressor can hydraulic compression, the gas outlet of evaporimeter generally all needs to ensure certain suction superheat, and general evaporimeter need to have 10%～30% heat exchange area for overheated heat exchange.Can there is larger flow resistance while passing through superheat section in the refrigerant in evaporimeter, cause refrigeration system loss in efficiency excessive.
In the patent of invention of Chinese patent CN102230681B disclosed " a kind of refrigeration system of evaporator outlet zero degree of superheat operation " by name, drive injector to realize assisted evaporative by economizer intermediate pressure flash steam is set, main evaporator can still can normally move without the outlet refrigerant degree of superheat.Although such scheme can solve flow resistance appears in refrigerant problem through superheat section, needs to increase the devices such as economizer, injector, auxiliary evaporator in this device, to existing equipment, repacking drops into larger.In addition, because economizer system itself is by pressing chamber tonifying Qi in compressor, also can significantly promote refrigerating capacity and the coefficient of performance of refrigeration unit, adopt this scheme can make this function of economizer completely lose.
Utility model content
The purpose of this utility model is to provide a kind of refrigeration system, can have the problem of flow resistance can effectively solve the refrigerant process superheat section in evaporimeter time.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of refrigeration system, the gas-liquid separator that comprises evaporimeter, is connected with the gas outlet of evaporimeter, the liquid outlet of described gas-liquid separator is connected with the inlet of evaporimeter by circulating pump, on the pipeline between described circulating pump and the inlet of evaporimeter, is also provided with check valve.
Preferably, on the pipeline between described gas-liquid separator and circulating pump, be also provided with stop valve; In the time that breaking down, circulating pump can close in time convenient maintenance.
Preferably, the exhaust outlet of described gas-liquid separator and the air entry of compressor are connected; Utilize the gas-liquid separator of compressor air suction mouth not need additionally to increase device.
Preferably, the inlet of described evaporimeter is also connected with the liquid outlet of condenser by expansion valve; Be convenient to inject new cold-producing medium.
Preferably, in described gas-liquid separator, be provided with fluid level controller, described fluid level controller is by control system controlled circulation pump and expansion valve; The operation of controlled circulation pump and the aperture of expansion valve, the liquid in guarantee gas-liquid separator is in normal level.
Compared with prior art, the utility model has the advantages that: evaporimeter does not need overheated heat exchange, and can ensure that hydraulic compression does not appear in compressor, utilize the gas-liquid separator of compressor air suction mouth, liquid refrigerant is separated, the refrigerant liquid being separated is sent to devaporation in evaporimeter again by circulating pump system, heat exchange property by native system finisher will be largely increased, and gas-liquid separator is very little to the pressure reduction of evaporator, so circulating pump only needs very little power just refrigerant liquid can be brought back to evaporimeter, it is lower that system realizes cost.
Brief description of the drawings
Fig. 1 is the schematic diagram of a kind of refrigeration system of the utility model.
Detailed description of the invention
Consult the embodiment that Fig. 1 is a kind of refrigeration system of the utility model, in figure, arrow is gas or liquid flow direction, a kind of refrigeration system, comprise evaporimeter 1, the gas-liquid separator 2 being connected with the gas outlet of evaporimeter 1, the liquid outlet of described gas-liquid separator 2 is connected with the inlet of evaporimeter 1, on pipeline between the inlet of the liquid outlet of described gas-liquid separator 2 and evaporimeter 1, be provided with successively stop valve 5 by liquid flow direction, circulating pump 3, check valve 4, the exhaust outlet of described gas-liquid separator 2 is connected with the air entry of compressor 6, the inlet of described evaporimeter 1 is also connected with the liquid outlet of condenser 8 by expansion valve 7.
From evaporimeter 1 refrigerant gas out, contain a certain amount of liquid refrigerant, by the gas-liquid separator 2 of compressor 6 air entries, liquid refrigerant is separated, the refrigerant liquid being separated is sent back in evaporimeter 1 and is gone by circulating pump 3.Meanwhile, in described gas-liquid separator 2, be provided with fluid level controller 9, described fluid level controller 9 is by the operation of control system 10 controlled circulation pumps 3 and the aperture of expansion valve 7, and the liquid in guarantee gas-liquid separator is in normal level.
Heat exchange property by native system finisher 1 will be largely increased, and gas-liquid separator 2 is very little to the pressure reduction of evaporimeter 1 inlet, so the power that 3 needs of circulating pump are very little just can bring back to evaporimeter 1 refrigerant liquid, it is lower that system realizes cost.Meanwhile, evaporimeter adopts the less evaporimeter of refrigerant side resistance, to reduce the power consumption of circulating pump, further improves the economy of system.
The foregoing is only specific embodiment of the utility model, but technical characterictic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
