Abstract
The utility model discloses a kind of without oily magnetic suspension air-cooled unit, it comprises compressor, evaporimeter, condenser and electric expansion valve, please supplement the annexation of each device, and wherein, described compressor is frequency conversion magnetic levitation compressor.The beneficial effect that the utility model has: 1, adopt degree of supercooling control mode, the degree of supercooling that refrigeration system fluid path keeps stable can be guaranteed, thus avoid because adopt flooded evaporator, make system fluid path coolant quantity unstable, fluid path shows that liquid mirror is discontented with, efficiency is not high, makes unit to keep Effec-tive Function; 2, stable degree of supercooling can be kept, namely keep sufficient liquid refrigerants at any time in liquid pipeline, so also just ensure that the source of the cooling hydrojet of compressor variable frequency module.
Description
Technical field
The utility model relates to a kind of without oily magnetic suspension air-cooled unit, belongs to technical field of refrigeration equipment.
Background technology
In traditional various types of refrigeration unit, the control of expansion valve substantially all adopts the mode of suction superheat to control, and no matter is heating power expansion valve, or electric expansion valve.
But, for TECS series air-cooled unit, above us and mention, the configuration of what its adopted is flooded evaporator and finned cooler.Because the volume of flooded evaporator medium side is relatively large, refrigerants a large amount of in system all remains in flooded evaporator, if adopt suction superheat to control, liquid pipeline shows that liquid mirror is easy to be discontented with, thus system does not just have degree of supercooling.
Utility model content
The purpose of this utility model provide a kind of without oily magnetic suspension air-cooled unit to solve in prior art existing the problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of without oily magnetic suspension air-cooled unit, it comprises compressor, evaporimeter, condenser and electric expansion valve, please supplement the annexation of each device, and wherein, described compressor is frequency conversion magnetic levitation compressor.This type of unit refrigerating capacity adjustable range is wide in range, and unit operation requires to regulate smooth steady.
Preferably, described evaporimeter is flooded evaporator, and described condenser is air-cooled condenser.
Preferably, described air-cooled condenser is finned surface cooler.
The beneficial effects of the utility model are mainly reflected in:
1, adopt degree of supercooling control mode, the degree of supercooling that refrigeration system fluid path keeps stable can be guaranteed, thus avoid because adopt flooded evaporator, make system fluid path coolant quantity unstable, fluid path shows that liquid mirror is discontented with, and efficiency is not high, makes unit to keep Effec-tive Function;
2, stable degree of supercooling can be kept, namely keep sufficient liquid refrigerants at any time in liquid pipeline, so also just ensure that the source of the cooling hydrojet of compressor variable frequency module.
Accompanying drawing explanation
Fig. 1 is the structural representation of TESC air-cooled unit in the utility model;
Fig. 2 is the degree of supercooling control method flow chart of electric expansion valve in the utility model;
Detailed description of the invention
A kind of structural representation without oily magnetic suspension air-cooled unit that the utility model provides as shown in Figure 1, comprises compressor C, flooded evaporator EV, air-cooled condenser BC and electric expansion valve EKV, and wherein, described compressor C is frequency conversion magnetic levitation compressor.The gaseous refrigerant of low-temp low-pressure enters compressor C, after being compressed, forms the gaseous refrigerant of HTHP by compressor C; Then enter into air-cooled condenser BC, after cooled heat release, become the liquid refrigerant of HTHP; And then after electric expansion valve EXV throttling, become the gas-liquid mixed refrigerant of low-temp low-pressure; After finally entering evaporimeter EV heat absorption, again become the gaseous refrigerant of low-temp low-pressure, electric expansion valve EXV is controlled by electronic expansion valve controls evil spirit module EKS.This type of unit refrigerating capacity adjustable range is wide in range, and unit operation requires to regulate smooth steady.
Preferably, described evaporimeter is flooded evaporator, and described air-cooled condenser is finned surface cooler.
As shown in Figure 2, it comprises the steps: control method flow process without oily magnetic suspension air-cooled unit described in the utility model

Utilize EKS control module to compare described actual degree of supercooling and degree of supercooling setting value, when actual degree of supercooling is greater than degree of supercooling setting value, driving electric expansion valve is outwarded winding by EKS control module, otherwise, drive electric expansion valve to screw.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
