Abstract
The utility model discloses an has air-conditioning system with unloading device, comprising a compressor, a condenser, an evaporator connected with a compressor in turn, a throttling device on the pipeline connecting with the evaporator, also includes a pressure by-pass valve, the pressure by-pass valve inlet is connected with condenser outlet pipe through pipeline, pressure by-pass valve outlet is connected with evaporator outlet pipe through pipeline, so that the pressure by-pass valve and evaporator form parallel connection. The utility model can save energy consumption of the unit, increase unit stability, at the same time, realize precise control of unit overload protection.
Description
Technical field
The utility model relates to a kind of hot pump in low temp hot water unit, specifically, relates to a kind of air-conditioning system with discharge mechanism.
Background technology
Among present heat pump water-heating machine field, in the especially general water-heating machine system, the system overload protection is comparatively simple.Control principle is that when system loading was excessive, evaporating temperature rose; evaporating pressure also rises thereupon, and the load that compressor will bear also just rises thereupon, when load rises to the degree that can bear above compressor; the overload protecting mechanism of compressor will start, and forces compressor to quit work.At this moment whole system is also just out of service.If be used in the bigger place of load, will cause great inconvenience to the user.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective of the prior art; a kind of air-conditioning system with discharge mechanism is provided, and this unit is guaranteeing under the prerequisite that the user requires the hot water temperature energy consumption of saving unit; improve the stability of unit, realize the accurate control of unit overload protection simultaneously.
For achieving the above object, the technical scheme that the utility model provides is as follows: construct a kind of air-conditioning system with discharge mechanism, the condenser, the evaporimeter that comprise compressor, be connected successively with compressor, be arranged on pipeline that evaporimeter is connected on throttling arrangement, also comprise a pressure by-passing valve, the import of described pressure by-passing valve is connected with the outlet conduit of condenser by pipeline, the outlet of pressure by-passing valve is connected with the outlet conduit of evaporimeter by pipeline, pressure by-passing valve and evaporimeter is constituted be connected in parallel.
Producing effect of air-conditioning system with discharge mechanism described in the utility model is: by a pressure by-passing valve is set in unit, the import of described pressure by-passing valve is connected with the outlet conduit of condenser by pipeline, the outlet of pressure by-passing valve is connected with the outlet conduit of evaporimeter by pipeline, pressure by-passing valve and evaporimeter is constituted be connected in parallel.When the too high and back pressure of the pressure at expulsion of unit is crossed when low; that part of cold-producing medium of overload is without evaporimeter and by the direct compressor that refluxes of pressure by-passing valve; reduce to enter the refrigerant flow of evaporimeter; thereby reach the purpose of unloading protecting; do not influence simultaneously the running of compressor again, refrigeration system is normally moved.Thereby the energy consumption that can save unit, the stability of raising unit realizes the accurate control of unit overload protection simultaneously.
Below in conjunction with drawings and Examples the air-conditioning system with discharge mechanism described in the utility model is described further:
Description of drawings
Fig. 1 is the structural representation that the utlity model has the air-conditioning system of discharge mechanism.
The specific embodiment
Below be the most preferred embodiment with air-conditioning system of discharge mechanism described in the utility model, therefore do not limit protection domain of the present utility model.
With reference to Fig. 1, construct a kind of air-conditioning system with discharge mechanism, the condenser 3, the evaporimeter 2 that comprise compressor 1, be connected successively with compressor 1, be arranged on the throttling arrangement 4 on the pipeline that is connected with evaporimeter 2, also comprise a pressure by-passing valve 5, the import of described pressure by-passing valve 5 is connected by the outlet conduit of pipeline with condenser 3, and the outlet of pressure by-passing valve 5 is connected by the outlet conduit of pipeline with evaporimeter 2, pressure by-passing valve 5 is constituted with evaporimeter 2 be connected in parallel.
Described throttling arrangement 4 is can be expansion valve, goes back capillary.
By a pressure by-passing valve 5 is set in unit; when the too high and back pressure of the pressure at expulsion of unit is crossed when low; that part of cold-producing medium of overload is without evaporimeter 2 and by the pressure by-passing valve 5 direct compressors 1 that reflux; reduce to enter the refrigerant flow of evaporimeter 2; thereby reach the purpose of unloading protecting; do not influence simultaneously the running of compressor 1 again, refrigeration system is normally moved, and has fundamentally solved refrigeration system once overload compressor 1 problem out of service.
Claims (1)
1, a kind of air-conditioning system with discharge mechanism, the condenser, the evaporimeter that comprise compressor, be connected successively with compressor, be arranged on pipeline that evaporimeter is connected on throttling arrangement, it is characterized in that, also comprise a pressure by-passing valve, the import of described pressure by-passing valve is connected with the outlet conduit of condenser by pipeline, and the outlet of pressure by-passing valve is connected with the outlet conduit of evaporimeter by pipeline, pressure by-passing valve and evaporimeter is constituted be connected in parallel.
