Problems solved by technology

[0002] In the existing multi-connection system with external units connected in parallel, the total energy efficiency during operation is the sum of the operating energy efficiency of a single external unit. If the internal unit is not running at full load, some modules of the external unit will stop, and the heat exchange of the external unit will be stopped. The server does not participate in the system operation and is in an idle waste state

Abstract

The invention discloses a multi-connection system, an outdoor machine component and a control method thereof. The outdoor machine assembly includes: a compressor, a reversing assembly, an outdoor heat exchanger, a control valve and a first stop valve, and the compressor has an exhaust port and an air return port. The reversing assembly includes first to fourth interfaces, the first interface is connected with the exhaust port, the fourth interface is connected with the air return port, and the second interface is suitable for being connected with the indoor unit combination. The first end of the outdoor heat exchanger communicates with the third interface. The control valve is connected with the second end of the outdoor heat exchanger. The first stop valve communicates with the first end and the third port of the outdoor heat exchanger respectively. According to the outdoor unit assembly of the embodiment of the present invention, the frequency of the compressor can be reduced while meeting the demand for cooling and heating, and the energy efficiency of the system can be improved to reduce the operating cost. It can also effectively improve the low-temperature heating capacity, reduce the defrosting time, and improve User comfort.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a multi-connected system, an outdoor unit assembly and a control method thereof. Background technique [0002] In the existing multi-connection system with external units connected in parallel, the total energy efficiency during operation is the sum of the operating energy efficiency of a single external unit. If the internal unit is not running at full load, some modules of the external unit will stop, and the heat exchange of the external unit will be stopped. The controller does not participate in the system operation, and is in an idle and wasteful state. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, an object of the present invention is to provide an outdoor unit assembly for a multi-split system, which can improve the operating energy efficiency of the ...
