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

Abstract

The invention discloses an air conditioner and a defrosting system thereof. The defrosting system comprises an enthalpy increasing compressor, an outdoor heat exchanger, an indoor heat exchanger and an economizer unit; the enthalpy increasing compressor comprises a medium-pressure chamber and an enthalpy nozzle which communicates with the medium-pressure chamber; an outlet end of the outdoor heat exchanger is connected with a flow dividing capillary tube and a defrosting liquid accumulation tube in parallel; the economizer unit is provided with a first flow channel and a second flow channel; a first end of the first flow channel selectively communicates with one of the flow dividing capillary tube and the defrosting liquid accumulation tube via a first pipeline system; a second end of the first flow channel communicates with the indoor heat exchanger via a main pipeline; the first end of the second flow channel is connected with the main pipeline via an auxiliary pipeline; the second end of the second flow channel is connected with the enthalpy nozzle of the enthalpy increasing compressor via a second pipeline system; the second pipeline system is provided with a valve device; and the auxiliary pipeline is provided with a throttling and pressure reducing component. By the arrangement, the defrosting system of the air conditioner disclosed by the invention can shorten the defrosting time and satisfy the comfort requirement of a user.

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...
