Abstract

The invention discloses a refrigerating system. The refrigerating system comprises a compressor, a condenser, a gas-liquid separator, a first throttling device, an evaporator and a supercooling heat exchanger, wherein the compressor, the condenser, the first throttling device, the gas-liquid separator and the evaporator are sequentially connected together through connecting pipes; the supercooling heat exchanger is also arranged on the outer pipe wall of the connecting pipe connected to an outlet of the condenser; an inlet of the supercooling heat exchanger is communicated with a gas outlet of the gas-liquid separator; and an outlet of the supercooling heat exchanger is communicated with an air inlet of the compressor. The supercooling heat exchanger is arranged on the connecting pipe of the outlet of the condenser and is used for further exchanging heat of a cold medium flowing from the condenser by using a gas cold medium separated by the gas-liquid separator. The two cold media are relatively high in temperature difference, and the cold medium flowing from the condenser can be further supercooled and can achieve higher supercooled degree, so that the ability and the energy efficiency of the cold media are improved. Therefore, a copper pipe and a fin of the heat exchanger can be correspondingly shrunk in volume, energy is saved, and the cost can also be reduced.

Description

technical field [0001] The invention belongs to the field of refrigeration, in particular to a refrigeration system capable of increasing the degree of subcooling, and belongs to the improvement technology of the refrigeration system. Background technique [0002] In order to build a "saving" society, the energy saving of air conditioners has attracted more and more people's attention, but in actual operation, some refrigerants are in a state of non-heat exchange, and this part of energy is wasted. If the wasted cooling capacity can be fully utilized, the energy efficiency can be improved more effectively, and more energy can be saved. In the refrigeration system, the refrigerant after passing through the throttling device is in the two-phase region. In the heat exchange of the evaporator, it is mainly the phase change potential heat exchange, and the temperature changes little, so the gaseous refrigerant after throttling is actually in the evaporator. There is no heat exch...
