Problems solved by technology

[0010] In addition, the state of condensation varies depending on the ambient temperature, and poor condensation of the refrigerant often occurs. If the condensation state is poor, non-condensable gas that is not completely condensed is generated on the outlet side of the condenser, and it may be supplied to the expansion valve side. question

Embodiment Construction

[0045] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0046] figure 1 A structural diagram of the refrigeration system of the present invention is shown.

[0047] Such as figure 1 As shown, the refrigeration system of the present invention includes: a compressor 10 for compression of a refrigerant; a condenser 20 for condenses a refrigerant compressed by the compressor 10; a reservoir 30 for temporarily stored The refrigerant liquid liquefied in the condenser 20; the expansion valve 40 causes the refrigerant liquid of the condensed high temperature high pressure to a low temperature and low pressure refrigerant gas; and the evaporator 50 that expands through the expansion valve 40 evaporation.

[0048] In the above compressor 10, the compressor is compressed by the low pressure gas circulating through the evaporator 50 to cause a high-temperature high pressure gas, and the refrigerant drawn from the evaporator 50 is...

Abstract

The present invention relates to refrigerating systems, and more specifically, relates to cooling of condensed gas that is installed in transport vehicle refrigerators, industrial refrigerators, air conditioners, and various cooling systems to adjust changes in accordance with seasonal changes or abnormal high-temperature changes in outside air temperature state, so as to properly maintain the refrigeration system of the refrigerant temperature, the refrigeration system of the present invention is characterized in that it includes: a suction pressure regulating valve, which is arranged on the first refrigerant pipeline, and the first refrigerant pipeline is connected to the above-mentioned evaporator and compressor Between the compressors, the suction pressure is maintained at a specified pressure in order to prevent the overload of the above-mentioned compressor; the condensed gas detection part is installed between the above-mentioned compressor and the expansion valve, and is used to detect the change of the cooling state of the condensed gas; and the electronic valve , installed in a bypass pipe, the bypass pipe is connected in parallel with one side of the first refrigerant pipe, and the suction amount of the refrigerant supplied from the evaporator to the compressor is monitored based on the detection signal of the condensed gas detection unit. Control.

Description

Technical field [0001] The present invention relates to a refrigeration system, more detailed, involving a cooling gas that changes from a condensation gas change according to the abnormal high temperature change of the season variation or external air temperature is adjusted to the transport vehicle refrigerator, industrial refrigerator, air conditioner, and various cooling systems. State, thereby appropriately maintaining a refrigeration system for refrigerant temperatures. Background technique [0002] Typically, the refrigeration system is condensed by a compressor that causes a refrigerant cycle, a condenser that condenses the compressed high temperature refrigerant, causes the condensing high-temperature high pressure refrigerant to low temperature and low pressure expansion valve, which is carried out to low temperature and low pressure expansion refrigerant Hygistization to cool the evaporator of surrounding air, suitable for vehicle refrigerator, air conditioning, and va...
