Problems solved by technology

[0010] However, the outdoor unit of the air conditioner in the prior art has the following disadvantages: when starting the compressors 102 and 103, a large starting force is required, and the air conditioner makes the compressors 102 and 103 repeatedly operate according to the difference between the temperature of the temperature-adjusting space and the set temperature. run / stop
Therefore, whenever the compressors 102, 103 are restarted, more power will be consumed

Abstract

The invention provides an outdoor machine of air conditioner and its operation method, comprising: a heat exchanger; a compressor; a coolant reflux device to return the coolant exhausted from the compressor. And its operation method comprise following steps: the first step that the compressor compresses the coolant according the preset temperature of temperature adjusting space; the second step that return the coolant exhausted by compressor into the compressor when the temperature of temperature adjusting space reaches the preset value in the first step; and the third step that stopping the return of coolant when the temperature of temperature adjusting space reaches the highest value of preset value in the second step. The advantages of said invention are that the side of coolant exhausted outlet of compressor and the side of adsorbing coolant are each mounted reflux pipes and electromagnetic valves, while the when the temperature of temperature adjusting space reaches the lowest value of preset value, it can continue the operation of compressor to reduce the waste of electricity of starting compressor.

Description

Technical field [0001] The present invention relates to the invention of the outdoor unit of the air conditioner, and in particular to the one that does not stop the compressor when the temperature of the temperature regulating space reaches the minimum value of the required temperature range, and allows the refrigerant discharged from the compressor to return to the inside of the compressor. Air conditioner outdoor unit and operation method of air conditioner outdoor unit. Background technique [0002] Such as figure 1 As shown, in the air conditioner in the prior art, in the case where the indoor unit is set in a one-to-one connection on the outdoor unit 100, hereinafter referred to as the first indoor unit 110, a secondary indoor unit can be connected according to the needs of the user, hereinafter referred to as The second indoor unit 120. That is, the prior art air conditioner includes an outdoor unit 100, a first indoor unit 110, and a second indoor unit 120. Among them, t...
