Problems solved by technology

[0004] The defect of the existing technology is that after the refrigerant evaporates in the evaporator, it returns to the gas-liquid separator of the system, and then returns to the compressor to enter the next cycle. The system cannot achieve complete evaporation and uniform distribution, which will inevitably waste Part of the cooling capacity of the system increases unnecessary power consumption of the system

Abstract

The embodiment of the invention provides a multiple-on-line system and a method for enhancing supercooling degree of the multiple-on-line system. The method is used for utilizing refrigeration capacity of a coolant which is not completely evaporated in the multiple-on-line system, thereby achieving the effects of energy saving and high efficiency of the system. The technical scheme of the embodiment of the invention is as follows: a heat exchanger is arranged inside a gas-liquid separator; one end of the heat exchanger is connected with a condenser through a first solenoid valve; the other end of the heat exchanger is connected with an evaporator through a second solenoid valve; and the multiple-on-line system also comprises a third solenoid valve which is connected with the first solenoid valve and second solenoid valve in parallel.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of household appliances, and in particular to a multi-connection system and a method for increasing the subcooling degree of the multi-connection system. Background technique [0002] The multi-connected air-conditioning system is a high-efficiency air-conditioning system that timely meets the indoor cooling and heating load requirements by controlling the refrigerant circulation volume of the compressor and the refrigerant flow rate entering the indoor heat exchanger in the air-conditioning system. [0003] The multi-connected air-conditioning system needs to use variable frequency compressors, multi-stage compressors, unloading compressors or a combination of multiple compressors to realize compressor capacity control. Electronic expansion valves or other auxiliary circuits need to be installed in the refrigeration system to adjust the flow rate of the indoor units. The refrigeran...
