Refrigeration system

Abstract

The embodiment of the invention discloses a refrigeration system. The refrigeration system comprises a first condenser and further comprises a second condenser and a first solenoid valve which are connected in series, wherein a cold medium outlet end of the second condenser is connected with an input end of the first solenoid valve; the second condenser and the first solenoid valve which are connected in series are connected with the first condenser in series or in parallel; when the first solenoid valve is switched on, a refrigerating agent stored in the second condenser is controlled to flow out and is overlapped with a refrigerating agent flowing out from the first condenser, so that the circulating amount of the refrigerating agent in the refrigeration system is adjusted. According to the refrigeration system provided by the invention, the first solenoid valve is controlled to be switched on at high frequency so that the second condenser participates in refrigeration circulation, and the heat exchange of the refrigeration system can be effectively enhanced and the refrigeration speed is improved; and the first solenoid valve is controlled to be switched on for a period of time and then to be switched off at low frequency, so that the flow of the refrigerating agent can be improved; and the heat exchange efficiency is easily improved, the low-frequency operation time is prolonged, the starting-up time and the starting-up rate are reduced, and the power consumption is effectively reduced.

Description

technical field [0001] Embodiments of the present invention relate to refrigeration technologies, and in particular to a refrigeration system. Background technique [0002] The frequency of the frequency conversion refrigerator changes accordingly with the change of temperature. When the temperature of the refrigerator is high, the compressor rotates fast, which can cool down as soon as possible. When the temperature of the refrigerator is low, the compressor runs at a low speed to maintain the temperature. The advantages of long life, energy saving and consumption reduction, and quietness. [0003] At present, the refrigeration system of the inverter refrigerator is as follows: figure 1 Shown is mainly composed of a compressor 10, a condenser 11 on the side wall of the refrigerator, an anti-condensation pipe 12, a dry filter 13, a capillary 14, an evaporator 15 and a liquid reservoir 16. Wherein the evaporator 15 has a fan motor 17, and a certain amount of refrigerant is ...
