Problems solved by technology

[0006] However, the control method for reducing the noise of the refrigeration cycle of the air conditioner in the prior art with the above structure has the following disadvantages: when the compressor stops working, the inertial medium continues to flow into the indoor unit side; The short tube where the medium is decompressed, the pressure difference between the front and rear ends of the short tube is relatively large, so even if the compressor stops working, the medium will continue to move into the short tube for a relatively long period of time, resulting in noise

Embodiment Construction

[0015] Referring to the accompanying drawings, the embodiments of the control method for reducing the noise of the refrigeration cycle of the air conditioner according to the present invention will be described in detail below.

[0016] figure 1 A structural diagram showing the refrigerating cycle of the air conditioner of the present invention. figure 2 A flowchart showing the control method of the present invention for reducing the noise of the refrigerating cycle of the air conditioner.

[0017] Such as figure 1 As shown, the refrigeration cycle of the air conditioner of the present invention generally includes an outdoor unit 8 and an indoor unit 18. The function of the above-mentioned outdoor unit 8 is to exchange heat between the medium and the outdoor air; the function of the above-mentioned indoor unit 18 is to make the medium and the air The indoor air performs heat exchange, and the above-mentioned indoor unit 18 and outdoor unit 8 are installed on the inside and ...

Abstract

The present invention relates to a control method for reducing noise produced by short tube of indoor side when the power supply is switched off. Said method includes the following stage: compressor operation stopping stage, switching off power supply of air conditioner and stopping compressor operation; flow path intercepting stage, intercepting medium flow path and preventing medium from flowing toward indoor machine and outdoor machine when the above-mentioned compressor is stopped; and above-mentioned noise preventing stage.

Description

technical field [0001] The present invention relates to a control method for reducing refrigerating cycle noise of an air conditioner, and further relates to a control method for reducing refrigerating cycle noise of an air conditioner capable of reducing noise generated by a short tube installed indoors when the power is turned off. 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] The refrigerating cycle of an air conditioner in the prior art generally includes an outdoor unit and an indoor unit. The above-mentioned outdoor unit is composed of a compressor, a condenser and an outdoor fan. The function of the above-mentioned outdoor unit is to exchange heat between the medium and the outdoor air; the above-mentioned indoor unit Consisting of a short tube, an eva...
