Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1 compressor, 2 water cooling heat exchangers, 3 drip trays, 4 air-cooled condensers, 5 condensation fans, 6 devices for drying and filtering, 7 evaporimeters, 71 evaporimeter super cooled sects, 72 evaporator evaporation sections, 8 evaporation fans, 9 throttling arrangements.
Detailed description of the invention
For ease of understanding technology contents of the present utility model, just by reference to the accompanying drawings its technical scheme is described further below.
As shown in Figure 1, a kind of refrigerator refrigeration system, comprises compressor 1, water cooling heat exchanger 2, drip tray 3, air-cooled condenser 4, device for drying and filtering 6 and evaporimeter 7.Described evaporimeter 7 is divided into super cooled sect 71 and evaporator section 72, and the connecting pipeline between described super cooled sect 71 and described evaporator section 72 arranges throttling arrangement 9.At described water cooling heat exchanger 2 place, correspondence is provided with condensation fan 5, and at described air-cooled condenser 4 place, correspondence arranges condensation fan 5, and at described evaporimeter 7 place, correspondence arranges evaporation fan 8.
R290 refrigeration working medium adopted by described compressor 1, and its one end connects one end of described water cooling heat exchanger 2.Described water cooling heat exchanger 2 is placed in described drip tray 3.Described water cooling heat exchanger 2 other end connects described air-cooled condenser 4, described air-cooled condenser 4 is connected with described evaporimeter 7 through described device for drying and filtering 6, described evaporimeter 7 connects the other end of described compressor 1, the super cooled sect 71 being specially described evaporimeter 7 connects described air-cooled condenser 4, and evaporator section 72 connects described compressor 1 other end.
The condensed water comb of described evaporimeter 7 is communicated with described drip tray 3, and what namely store in drip tray 3 is the condensed water generated in commercial display cases, its energy-saving and environmental protection.In order to make the inflammable and explosive risk avoiding R290 refrigeration working medium to exist in application to greatest extent, all connections of this circulatory system all adopt welding manner, and the electric elements be applied to all adopt anti-static elements.
The ODP=0 of R290 refrigeration working medium, GWP=3, its boiling point and critical-temperature and R22 closely, are a kind of natural refrigerant.R290 refrigeration working medium is cheap, and equal commercial display cases is compared R404a refrigeration working medium, and charging amount is 0.45-0.55 times of R404a.But the inflammable and explosive characteristic of R290 refrigeration working medium tool, for preventing accident, whole refrigeration system should be made all to adopt welding manner to connect, automatically controlled components and parts preventing from adopt easy pyrophoric components and parts, namely antistatic treatment is adopted to the electrical equipment adopted, effectively evade the risk occurring blast.
Product energy-conservation on, from compressor 1 out be in high temperature, the R290 refrigeration working medium of high pressure conditions is before entering air-cooled condenser 4, be introduced in preposition water cooling heat exchanger 2 and lower the temperature, this water cooling heat exchanger 2 is arranged on to contain and flows out the drip tray 3 of condensed water in commercial display cases, by condensed water in drip tray 3 to the R290 refrigeration working medium cooling in water cooling heat exchanger 2, condensation fan 5 is also provided with for improving cooling effect, the water cooling heat exchanger 2 of the condition of high temperature can make it evaporate to the heating of the condensed water of described drip tray 3 li, whole water-cooled heat transfer process does not require separately input water source, and make the spontaneous condensed water of recovery commercial display cases, so the water saving of water-cooled heat transfer process, energy-conservation, and can significantly reduce R290 refrigeration working medium temperature in advance, overcome its inflammable and explosive property.From described water cooling heat exchanger 2 R290 refrigeration working medium out after described air cooling heat exchanger 4, successively enter device for drying and filtering, then enter the super cooled sect 71 of evaporimeter 7, lower the temperature at the low-temperature circulating wind of super cooled sect 71 by commercial display cases inside, realize the excessively cold further of R290 refrigeration working medium, finally enter after throttling arrangement 9 again in the evaporator section 72 of evaporimeter 7, carry out the evaporation of R290 refrigeration working medium, for the cooling of refrigerator internal environment, finally return compressor 1, realize a complete kind of refrigeration cycle.
Except the technical characteristic described in description, be the known technology of those skilled in the art.
