Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 As shown, the specific steps of the method for handling compressor failures of some outdoor units of the multi-connected air conditioner during heating in the present invention are as follows.

[0017] a. Connect the outlet of the outdoor heat exchanger 3 of each outdoor unit with the outlet of the outdoor heat exchanger 3 of an outdoor unit adjacent to the outdoor unit with a connecting pipeline 2 with a ball valve 1 .

[0018] b. In the heating mode, each outdoor unit operates normally. Once the compressor 4 of a certain outdoor unit fails to work normally, open the connecting pipe 2 between the faulty outdoor unit and an adjacent normal outdoor unit. ball valve 1.

[0019] c. After the refrigerant passes through the indoor heat exchangers of each indoor unit for heat exchange, it enters the same refrigerant circulat...

Abstract

The invention discloses a processing method for compressor faults of some outdoor units of a multi-coupled air conditioner during a heating process. The processing method comprises the following steps: using a connecting pipeline (2) with a ball valve (1) for connecting an outlet of an outdoor heat exchanger (3) of each outdoor unit with the outlet of the outdoor heat exchanger (3) of an adjacent outdoor unit; normally running each outdoor unit under a heating mode; opening the ball valve (1) of the connecting pipeline (2) between a fault outdoor unit and an adjacent normal outdoor unit after a compressor (4) of one outdoor unit is in fault and cannot normally work. According to the processing method, a specially-assigned person does not need to repair on-site and the self-regulation of the machine unit can be utilized to quickly and efficiently solve the problem of insufficient heat exchange amount caused by the faults of part of compressors.

Description

technical field [0001] The invention relates to a multi-connected air conditioner unit, referred to as a multi-connected air conditioner, and specifically relates to a treatment method for failure of compressors of some outdoor units of a multi-connected air conditioner during heating. Background technique [0002] The multi-connected air conditioner unit in the prior art includes a plurality of outdoor units connected in parallel, a plurality of indoor units connected in parallel, and two refrigerant circulation main pipes connecting the indoor units and the outdoor units. The multiple outdoor units connected in parallel communicate with the multiple indoor units connected in parallel through two main refrigerant circulation pipes. [0003] Each outdoor unit includes compressor, oil separator, four-way reversing valve, outdoor heat exchanger (evaporator in heating mode), outdoor unit electronic expansion valve and gas-liquid separator. The outlet of the compressor is conne...
