Abstract
The utility model discloses a small-sized refrigerating system which is composed of a compressor, a condenser, a throttling device and an evaporator. Refrigerants are repeatedly circulated in the system, a pressure regulator and a liquid accumulator are further connected between the condenser and a dry filter in series, the pressure regulator can regulate the filling capacity of the refrigerants in the condenser according to a set pressure value to regulate the heat exchange area of the condenser, the pressure of the system is kept constant, and the system is guaranteed to operate normally. The liquid accumulator can store, buffer and regulate the refrigerants of the system to adapt to refrigerant flow changes caused by the high pressure change of the refrigerating system, system pressure is stable, the stable circulation pressure of the refrigerants in the refrigerating system can be achieved better with low cost, and therefore the stability of the continuous operation and the combined operation cost of the whole system are improved.
Description
Technical field
The utility model relates to a kind of refrigeration system, but particularly a kind of small refrigeration systems of year round cooling.
Background technology
The small refrigeration systems that can use the whole year at present in order to keep efficiency in year-round operation, variation must conform, guarantee that refrigeration system operating efficiency and reliable most crucial content are the circulating pressures of keeping system inner refrigerant, concrete method: one, be the frequency of regulating condensation fan, to control the air quantity of condenser heat exchange, the high pressure of system is maintained in normal range of operation, and the processing cost of the method is higher; Two, be that the start and stop of controlling blower fan by the condensing pressure switch carry out the regulating system high-pressure, the shortcoming of the method is that the circulatory system concussion of cold-producing medium is large and extremely unstable; Three, be to change the heat exchange area of condenser by magnetic valve, the method causes the heat exchange area of condenser to change greatly, and refrigerant-cycle systems pressure is also unstable, and the complicated cost of system pipeline is high.
The utility model content
The utility model is in order to overcome above-mentioned defect of the prior art, by pressure-regulating valve being set in small refrigeration systems and, for the reservoir of refrigeration system, guaranteeing to realize better with lower cost the stability of refrigeration system internal pressure.
For achieving the above object, the utility model provides a kind of small refrigeration systems, by compressor, condenser, throttling arrangement and evaporimeter, formed, cold-producing medium reciprocation cycle in system flows, wherein on the access path of condenser and evaporimeter, be serially connected with device for drying and filtering and throttling arrangement, between evaporimeter and compressor, be provided with gas-liquid separator; Also be serially connected with pressure regulator and reservoir between condenser and described device for drying and filtering, pressure regulator is adjusted the filling quantity of refrigerant of condenser inside and is regulated the change heat exchange area, make the pressure of system remain stable, the assurance system is normally moved, reservoir stores the liquid refrigerant after pressure regulator, cold-producing medium that can liquid towards carries out store buffer, and the variation with the caused refrigerant flow of variation that adapts to refrigeration system, maintain system pressure stable.
In technique scheme, condenser is the copper pipe fin type structure.
In technique scheme, also be provided with the observation window of refrigerant condition in observing system between device for drying and filtering and throttling arrangement.
Compared with prior art, the utility model by arranging pressure-regulating valve and for the reservoir of refrigeration system in small refrigeration systems, guarantee to realize better with lower cost the pressure stability of refrigeration system, from improving whole system stability and the integrated operation cost of operation continuously.
The accompanying drawing explanation

Mark the following drawings mark thereon by reference to the accompanying drawings:
The 1-compressor, 2-condenser, 3-pressure-regulating valve, 4-reservoir, 5-device for drying and filtering, 6-observation window, 7-throttling arrangement, 8-evaporimeter, 9-gas-liquid separator.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of the specific embodiment.
A kind of small refrigeration systems of the present utility model, as shown in Figure 1, by compressor 1, condenser 2, throttling arrangement 7 and evaporimeter 8, formed, cold-producing medium reciprocation cycle in system flows, wherein on the connecting line of condenser 2 and evaporimeter 8, be serially connected with device for drying and filtering 5 and choke valve 7, between evaporimeter 8 and compressor 1, be provided with gas-liquid separator 9; Also be serially connected with pressure regulator 3 and reservoir 4 between condenser 2 and described device for drying and filtering 5, the filling quantity of refrigerant that pressure regulator 3 can be adjusted condenser inside according to pressure set points is regulated the change heat exchange area, make the pressure of system remain constant, the assurance system is normally moved; Reservoir 4, store the liquid refrigerant through pressure regulator 3 after, and cold-producing medium that can liquid towards carries out store buffer, and the variation with the caused refrigerant flow of variation that adapts to refrigeration system, maintain system pressure and stablize.
Further as shown in Figure 1, condenser 3 is the copper tube and fin structure heat exchanger.
Further as shown in Figure 1, also be provided with the observation window 6 of observing system refrigerant condition between device for drying and filtering 5 and choke valve 7, be convenient to system is carried out to manual intervention.
The utility model by arranging pressure-regulating valve and for the reservoir of cold-producing medium in small refrigeration systems, guarantee to realize with lower cost that better the circulating pressure of refrigeration system inner refrigerant is stable, from improving whole system stability and the integrated operation cost of operation continuously.
Above disclosed be only a specific embodiment of the present utility model, still, the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
