Abstract

The invention discloses an air-conditioner and a method for switching the working mode of the air-conditioner. The method solves the problem of high noise generated when the working mode of the air-conditioner is switched in the prior art. The air-conditioner comprises an indoor unit, an outdoor unit and a liquid pipe, a low-pressure air pipe, a low-pressure air pipe valve, a high-pressure air pipe and a high-pressure air pipe valve connected between the indoor unit and the outdoor unit; the air-conditioner also comprises a liquid pipe throttling device, a low-pressure air pipe throttling device and a high-pressure air pipe throttling device, wherein the liquid pipe throttling device is connected in series in the liquid pipe; the low-pressure air pipe throttling device is connected in parallel with the low-pressure air pipe valve; and the high-pressure air pipe throttling device is connected in parallel with the high-pressure air pipe valve. By using the technical scheme, the pressureof a coolant can be changed stably, and heat expansion and cold contraction effects are reduced, so that the noise generated when the working mode of the air-conditioner is switched is reduced.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner and a method for switching working modes of the air conditioner. Background technique [0002] As an air conditioning device, air conditioners have been widely used. figure 1 It is a schematic diagram of an air conditioner structure according to the prior art. [0003] like figure 1 As shown, the structure of an existing three-pipe heat recovery multi-connected air conditioner group includes an outdoor unit 13, a high-pressure air pipe 14, a low-pressure air pipe 15, a liquid pipe 16, a first indoor unit 21, and a first indoor unit high-pressure air pipe 17 , the first indoor unit low pressure air pipe 18, the first indoor unit liquid pipe 23, the second indoor unit 24, the second indoor unit liquid pipe 29, the second indoor unit low pressure air pipe 27, the second indoor unit high pressure air pipe 28. The existing air conditioner also in...
