Abstract
The utility model relates to a refrigerating circuit, in particular to a refrigerator refrigerating circuit, which can effectively maintain the pressure of a refrigerating circuit in the startup of the refrigerator. The refrigerator refrigerating circuit comprises a compressor, a condenser, a device for drying and filtering, a capillary, an evaporator and a return pipe, which are sequentially connected to form a circuit. An electromagnetic valve is arranged between the compressor and the return pipe, as well as between the capillary and the device for drying and filtering. A pressure maintaining capillary is arranged between the two electromagnetic valves. In the refrigerator refrigerating circuit, the pressure maintaining device is released after the restart of the compressor and working pressure difference can form in the system at once, thus shortening the time for forming pressure difference in normal situation, further improving the efficiency of refrigeration and achieving the effects of saving energy and reducing consumption.
Description
Technical field
The utility model relates to a kind of refrigerating circuit, relates in particular to a kind of refrigerating circuit of refrigerator.
Background technology
The refrigerating circuit of refrigerator of the prior art, generally all comprise compressor, condenser, device for drying and filtering, capillary, evaporimeter, muffler, they are in turn connected to form the loop, this basic refrigerating circuit is in compressor start beginning, operating pressure to inner high pressure that forms of systemic circulation and low-pressure section is poor, needs the regular hour.Compressor is after the shutdown that runs well, and after compressor started once more by the time, it was poor to form operating pressure in the system at once, and refrigeration efficiency during this period of time is poor, and has wasted energy to a certain extent.
Summary of the invention
The purpose of this utility model is to overcome above defective, provides a kind of when refrigerator starts, and can carry out refrigerating circuit is carried out the refrigerator refrigeration loop of pressurize effectively.
The technical scheme of refrigerator refrigeration loop of the present utility model is such: it comprises compressor, condenser, device for drying and filtering, capillary, evaporimeter, muffler, they are in turn connected to form the loop, between compressor and the muffler magnetic valve is set, between capillary and the device for drying and filtering magnetic valve is set, between these two magnetic valves, the pressurize capillary is set.
Magnetic valve between muffler and the compressor is arranged on the porch of compressor.
Magnetic valve is set to two-position three way magnetic valve.
Refrigerator refrigeration loop of the present utility model, after compressor started once more, pressurizer discharged, and it is poor to form operating pressure in the system, has shortened to form the time of pressure differential under the normal condition, thereby has improved the efficiency of refrigeration, reaches energy-saving and cost-reducing effect at once.
Description of drawings
Fig. 1 is the block diagram of the refrigerating circuit of refrigerator of the present utility model.
The specific embodiment
As shown in the figure, it comprises compressor the refrigerating circuit of refrigerator of the present utility model, condenser, device for drying and filtering, capillary, evaporimeter, muffler, they are in turn connected to form the loop, between compressor and the muffler magnetic valve is set, between capillary and the device for drying and filtering magnetic valve is set, between these two magnetic valves, the pressurize capillary is set, magnetic valve between muffler and the compressor is arranged on the porch of compressor, magnetic valve is set to two-position three way magnetic valve, two two-bit triplet magnetic valves and capillary play the effect to the pressurize of refrigeration system together, under the normal operating condition, refrigeration system inside is to exist a rational pressure differential, and compressor outlet is to this part of throttling arrangement and high-pressure section is exactly.A basic refrigeration system is in compressor start beginning, and is poor to this operating pressure of inner high pressure that forms of systemic circulation and low-pressure section, needs the regular hour.The use of this pressurizer; meaning is exactly; compressor is after the shutdown that runs well; high-pressure section to system carries out pressurize, and after compressor started once more by the time, pressurizer discharged; to form operating pressure in the system poor at once; shortened forming the time of pressure differential under the normal condition, thereby improved the efficiency of refrigeration, reached energy-saving and cost-reducing effect.This part of the magnetic valve that the pressurize capillary is connected has been put into the position before the suction port of compressor; this is to hidden danger of quality that piston impact caused when having removed start after the compressor shutdown; pressurize effect when also Cheng Gong the high-pressure section in the refrigeration system has been implemented compressor shutdown, thus reach energy-saving and cost-reducing effect safely and efficiently.
The refrigerating circuit of refrigerator of the present utility model, simple in structure, energy conservation and consumption reduction effects is obvious, can be extensive use of in the refrigerator field.
