Abstract

The invention provides an air conditioner and a control method thereof. The air conditioner comprises a compressor (1), an indoor heat exchanger (2), a throttling device (3), a first by-pass line (4)and an outdoor heat exchanger (5), wherein the throttling device (3) is arranged on a pipeline between the indoor heat exchanger (2) and the outdoor heat exchanger (5), a first end of the first by-pass line (4) is connected to the outdoor heat exchanger (5), the first by-pass line (4) is used for conveying a high-temperature refrigerant to the outdoor heat exchanger (5), and a first control valve(6) used for controlling the on-off state of the first by-pass line (4) is arranged on the first by-pass line (4). According to the air conditioner, the defrosting cycle of the air conditioner can beprolonged, the defrosting time of the air conditioner can be shortened, and the indoor comfort can be improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioner and a control method thereof. Background technique [0002] When the heat pump air conditioner is heating at low temperature, due to the influence of frosting and defrosting, it will cause large fluctuations in indoor temperature and poor comfort. Therefore, various means are adopted in the prior art to reduce the impact of defrosting on the indoor temperature. [0003] In the Chinese invention patent with application number 201210311278.1, an air conditioner is disclosed. By dividing the indoor heat exchanger into two parts (the first indoor heat exchanger and the second indoor heat exchanger), defrosting is required on the outdoor side , the four-way valve is switched to defrost. After passing through the outdoor heat exchanger, the high-temperature refrigerant first flows through the second indoor heat exchanger, then flows through the...
