Description
[technical field]
The present invention relates to a kind of complete machine show cabinet system, especially a kind of complete machine type merchandise display cabinet system that is used for the fresh-keeping and cold storage of food, beverage and fresh pesticide herd product.
[background technology]
Now, fresh-keeping and cold storage or the freezing goods showing cabinet that is used for food, beverage and fresh pesticide herd product become the indispensable equipment in supermarket and convenience store.These showcases can be open, also can be provided with door, be used to provide a cold storage environment with merchandise display such as fresh food, beverages to client.
In order to make a suitable cold storage environment, usually, the refrigeration system of showcase comprises following assembly at least: compressor, condenser, at least one unites evaporimeter, throttle mechanism such as float-ball type expansion valve, heating power expansion valve or choke type expansion valve (capillary) etc. in showcase, and these assemblies are connected suitable refrigerant line in the closed circulation loop.Cold-producing medium in the evaporimeter is ebullition, gasification under evaporating pressure, compressor constantly aspirates the steam that produces in the evaporimeter, and it is compressed to condensing pressure, refrigerant gas with HTHP is sent to condenser then, equipressure is cooled off and is condensed into liquid under condensing pressure, and liberated heat is passed to cooling medium (normally water or air) when refrigerant cools and condensation.Be higher than the temperature of cooling medium with the corresponding condensation temperature of condensing pressure.Condensed liquid refrigerant enters evaporimeter by throttle mechanism, when cold-producing medium passes through expansion valve, pressure drops to evaporating pressure from condensing pressure, the partially liq gasification, the temperature of remaining liq is reduced to evaporating temperature, and therefore the cold-producing medium that comes out from expansion valve becomes the two-phase mixture that temperature is an evaporating temperature.Liquid in the mixture evaporates in evaporimeter, and this process cold-producing medium is drawn its needed gasification latent heat from be cooled article or air, makes be cooled article or air themperature be reduced to desirable value.And the cold-producing medium after the gasification is sucked by compressor, thus the next circulation of beginning.
According to above-mentioned refrigeration mechanism, in a merchandise display cabinet system, adopt refrigerant condenser usually as system core parts.Air circulation system in the showcase is delivered to evaporimeter with the return air damp-heat air in the display area, carry out heat exchange with cold-producing medium there, being cooled becomes the low temperature cold dry air after drying, and further inject the merchandise display zone of showcase by the showcase cold air path, wherein exhibit is cooled off; Or in open showcase, between the surrounding air of cooling merchandise display zone and showcase vicinity, form a cold air curtain, thereby the commodity and the external environment condition of display area separated.
In the existing merchandise display cabinet system, the work evaporating temperature of refrigerant condenser is about about-15 ℃, and the evaporating temperature of employed common evaporimeter is about-10 ℃～-8 ℃.Because the performance of refrigeration compressor changes with the variation of evaporating temperature and condensation temperature, wherein the variation of evaporating temperature has bigger influence to its performance, reduction along with evaporating temperature, the refrigerating capacity and the refrigerating efficiency of circulation obviously descend, therefore, be in operation as long as can satisfy the temperature requirement of the object that is cooled, should make refrigeration machine keep higher evaporating temperature as much as possible, to guarantee to obtain bigger refrigerating capacity and better economic.
Thereby, for aforementioned existing merchandise display cabinet system, if can improve the evaporating temperature of evaporimeter, the compression ratio of refrigeration system is reduced, the operating condition of the core component compressor of system reaches the requirement of air-conditioning system, then not only can reduce the power consumption of system, the noise during the mitigation system operation also more helps providing complete machine type structure with the goods showing cabinet system integration for one.Therefore, provide a kind of so novel complete machine type show cabinet system, be one and have great and innovation positive effect for the present technique field.
