Problems solved by technology
[0004] However, in the prior art, most of the air-conditioning systems use ordinary variable-frequency high-pressure chamber scroll compressors, which have the disadvantages of "same frequency, small flow rate, and low power consumption"
This shortcoming will prolong the defrosting time and reduce the user's comfort experience

The invention discloses an air conditioner and its defrosting system. The defrosting system includes an enthalpy increasing compressor, an outdoor heat exchanger, an indoor heat exchanger and an economizer. The outlet port of the outdoor heat exchanger is connected with a shunt capillary and a defrosting liquid accumulation pipe in parallel. The economizer has a first flow channel and a second flow channel. The first end of the first flow channel can pass through the first pipeline system. It is selectively connected with one of the shunt capillary and the defrosting liquid accumulation pipe. The second end of the first flow channel is connected with the indoor heat exchanger through the main path, and the first end of the second flow path is connected with the main path through the auxiliary path. The second end of the second flow channel is connected to the enthalpy injection port of the enthalpy increasing compressor through the second pipeline system. The second pipeline system is provided with a valve device; the auxiliary circuit is provided with a throttling and pressure reducing component. With such arrangement, the defrosting system of the air conditioner provided by the present invention can shorten the defrosting time and meet the user's requirements for comfort.
Description
technical field [0001] The present invention relates to the technical field of air conditioners, more specifically, to an air conditioner and its defrosting system. Background technique [0002] When the air conditioning system operates in heating mode in a humid and cold environment, the outdoor heat exchanger is used as an evaporator. Since the surface temperature of the outdoor heat exchanger is lower than 0°C, the gaseous humid air in the outdoor air is easy to flow in the outdoor heat exchanger. Frost is condensed on the surface of the outdoor fan, and under the drainage of the outdoor fan, the frost will cover the entire outdoor heat exchanger, blocking the heat exchange between the heat exchanger and the air, so that the outdoor unit cannot absorb heat from the outside, resulting in a drop in the outlet air temperature of the indoor unit , unable to generate hot air, resulting in poor comfort, but also endangering the safety of the unit. [0003] In order to meet the...
