Problems solved by technology

[0010] However, in the hybrid air conditioner of the prior art as described above, power is supplied to each of the indoor units 10 according to different installation locations. When the power supply to the indoor unit 10 is interrupted, the refrigerant supplied to the outdoor unit 20 flows into the outdoor unit 20 in a state where the heat exchange in the indoor heat exchanger 11 is not sufficiently performed, and the refrigerant is released by hydraulic compression operation or the like. The aforementioned compressor 23 is damaged

Abstract

The emergency power supply for composite air conditioner features in the outdoor machine with compressors and outdoor heat exchangers, indoor heat exchanger, at least one indoor machine at one side of the indoor heat exchanger with electric indoor inflation device connecting with regular power, emergency power supply providing power for said electric indoor inflation device connected with the electric indoor inflation device when the regular power is cut off, and a control section controlling the cut off flow of said electric indoor inflation device connected with said emergency power supply section when the regular power is cut off. It can prevent the damage to the compressor due to cut off of regular power supply.

Description

technical field [0001] The present invention relates to a composite air conditioner with an emergency power supply part, and more specifically relates to, when the power supply of an indoor unit is suddenly interrupted, the flow path of the indoor unit whose power supply is interrupted is cut off, thereby preventing A composite air conditioner with an emergency power supply unit that can damage the compressor due to power supply interruption. Background technique [0002] An air conditioner is a device that can adjust the temperature, humidity, air flow and freshness of the air, and keep the indoor environment comfortable. The above-mentioned air conditioners can be classified into an integrated type air conditioner and a split type air conditioner according to the structure of their units. Wherein, the above-mentioned integrated air conditioner contains an indoor unit and an outdoor unit in a single shell; the above-mentioned split type air conditioner uses a compressor an...
