Abstract

The present invention relates to a freeze-circulation process of air conditioner and control method for reducing its noise produced by short pipe placed in indoor side when the power supply is switched off. Said freeze-circulation and control method can obtain the following effects: between outdoor machine and indoor machine a change-over device is set, when the compressor is stopped, the medium flow path of the above-mentioned outdoor machine and indoor machine is changed by change-over device, so that it can prevent the medium from further flowing into indoor side, the medium is not passed through the interior of short pipe placed in indoor side so as to can prevent the short pipe interior from producing noise. Besides, when the compressor is stopped, the medium flow path is changed, said indoor machine and outdoor machine have respective independent medium circulation flow path.

Description

technical field [0001] The present invention relates to a refrigerating cycle of an air conditioner and a control method for reducing its noise, and further relates to a refrigerating cycle of an air conditioner capable of reducing noise generated by a short tube (short tube) installed indoors when the power is turned off, and a control method for reducing its noise method. Background technique [0002] In a general air conditioner, the working fluid passes through a compressor, a condenser, an expansion valve, and an evaporator, and transfers heat from a low-temperature part to a high-temperature part for cooling or heating. [0003] Refer to the attached figure 1 and figure 2 , the refrigerating cycle of the conventional air conditioner will be described. figure 1 A structural diagram showing a refrigeration cycle of a prior art air conditioner. figure 2 A block diagram showing another embodiment of the refrigerating cycle of the prior art air conditioner. [0004] ...
