What is single cycle refrigeration for refrigerators? And double cycle refrigeration and the difference

1, single-cycle refrigeration system is mostly used for affordable, mechanical temperature control, freezing capacity is generally in the 4 kg or so;

2, double-cycle price is generally more than 3,000 yuan, computerized temperature control, freezing and refrigeration can be independently adjusted, freezer can be independently shut down, freezer cold power in more than 12 kg.

Single-cycle refrigeration: refrigeration system has only one evaporator, driven by this one evaporator refrigeration and freezing two boxes refrigeration, refrigerator operation of the two boxes at the same time refrigeration, this type of refrigerator is generally by the freezer thermostat or temperature sensing head control temperature, freezing temperature can not be adjusted individually.

Double-cycle refrigeration: there are two evaporators in the refrigeration system, installed in the refrigerator and freezer, by the solenoid valve to control the flow of refrigeration liquid, so as to achieve the effect of separate refrigeration of the refrigerator and freezer, such refrigerators can be individually controlled the temperature of the refrigerator and the freezer, thus reducing the refrigeration area, so that the refrigerator is more energy-efficient and refrigeration capacity is stronger.

Refrigeration Technology p>Refrigeration Technology

The research of refrigeration technology can be summarized in the following three aspects:

1) Research on the methods of obtaining low temperatures and the related mechanisms, as well as the refrigeration cycle corresponding to this. Thus, the refrigerator to provide satisfactory performance of the working medium. Mechanical refrigeration is realized only through changes in the thermal state of the refrigerant.

②Study the nature of the refrigerant. Thermophysical properties of refrigerant is the cycle analysis and calculation of the basic data. In addition, in order to make the refrigerant can be practically applied, it is also necessary to master its general physicochemical properties. Including its working principle, performance analysis, structural design.

3 research to realize the refrigeration cycle must be a variety of mechanical and technical equipment. As well as the refrigeration plant process organization, system design. In addition, there are thermal insulation problems, automation of refrigeration devices, and so on.

Refrigerator defrosting has a high trick:

Some refrigerators need to defrost, artificial refrigerator defrosting both time-consuming and laborious, and defrosting effect is very poor. Here to recommend you a defrosting tricks.

According to the size of the refrigerator freezer, cut a piece of plastic film slightly thicker, pasted on the freezer frost wall, do not have to use any adhesive, a paste that becomes. When defrosting, the food in the freezer will be temporarily removed, and then remove the plastic film shake, frost can all fall off, and then re-apply a film, put in food, continue to use.

Energy saving:

Keep away from heat sources, keep the gap:

Every 5℃ increase in temperature around the refrigerator, its internal power consumption should be increased by 25%. Therefore, it should be placed as far away from the heat source as possible, in a ventilated and shady place. Hot food should not be put directly into the refrigerator, and then put it in when it reaches room temperature. Food in the freezer is best packaged in small plastic bags, can be frozen very quickly, not easy to dry, but also to avoid moisture into frost; food should not be loaded too full, and the refrigerator wall should be left between the gap to facilitate the flow of cold air; frozen food, it is best to have a plan to transfer it to the freezer to thaw before eating.
