Abstract

The invention discloses a heat recovery multi-connection outdoor unit and a heat recovery multi-connection unit. The outdoor unit has a first interface and a second interface. The outdoor unit includes: a compressor, which has an exhaust port and an air return port; The component has a first valve port to a fourth valve port, the first valve port is connected to the exhaust port, the second valve port is connected to the return air port, and the third valve port is connected to the first port; outdoor heat exchanger, outdoor heat exchange The first end of the heat exchanger is connected to the fourth valve port, and the second end of the outdoor heat exchanger is connected to the second port; a plurality of one-way valves, each one-way valve has a conduction end and a cut-off end, each one-way valve One-way conduction in the direction from the conduction end to the cut-off end, a plurality of one-way valves include the first to sixth one-way valves; a throttling element, the throttling element is connected in series between the third one-way valve and the outdoor heat exchanger ;Gas-liquid separator. The outdoor unit with multiple heat recovery units of the present invention is beneficial for the compressor to obtain the degree of suction superheat, and at the same time can also improve the energy efficiency of the multiple heat recovery units.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to an outdoor unit of a heat recovery multi-connection unit and a heat recovery multi-connection unit. Background technique [0002] With the development of air-conditioning technology and the strengthening of people's concept of environmental protection, heat recovery multi-line is more and more popular in the market. In the heating mode, the outdoor heat exchanger as the evaporator can hold less refrigerant than the condenser in the cooling mode, and the excess refrigerant is usually stored in the gas-liquid separator. Specifically, in the heating mode, the refrigerant flows to the throttling element in the switching device to throttle and reduce pressure, and then forms a gas-liquid two-phase and enters the pipeline. Due to the large amount of gaseous refrigerant in the pipeline, the amount of refrigerant that can be stored is very small , more liquid refrigerant is stored...
