Abstract

The embodiment of the invention provides an outdoor unit, an air conditioning system and a defrosting method of the air conditioning system, and relates to the field of air conditioners. Defrosting is achieved when operating of a compressor is not stopped. The outdoor unit comprises the compressor, a four-way reversing valve, an outdoor heat exchanger, a throttling device, a three-way stop valve, a two-way stop valve, a first gate valve, a second gate valve, a heat accumulator and a three-way element. The inlet end of the first gate valve is connected to a pipeline between the second end of the throttling device and the two-way stop valve, and the outlet end of the first gate valve is connected with the inlet end of the heat accumulator. The inlet end of the second gate valve is connected to a pipeline between the outlet end of the compressor and a first port of the four-way reversing valve, and the outlet end of the second gate valve is connected to a pipeline between the first end of the throttling device and the second end of the outdoor heat exchanger. A third port of the four-way reversing valve is connected with the first inlet end of the three-way element, and the outlet end of the heat accumulator is connected with the second inlet end of the three-way element. The outlet end of the three-way element is connected with the inlet end of the compressor.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to an outdoor unit, an air conditioning system and a defrosting method thereof. Background technique [0002] During the heating process of the air conditioning system, when the outside temperature is low, frost is easy to form on the outdoor heat exchanger, which reduces the heat exchange effect of the outdoor heat exchanger, thereby affecting the heating function of the air conditioning system. When frosting reaches a certain level, the heating effect of the indoor heater will be reduced, and even the indoor heat exchanger will be unable to heat, that is, it will not be able to blow out heating air higher than the indoor temperature. Therefore, it is necessary to remove the frost on the outdoor heat exchanger to prevent it from affecting the heating function of the air conditioning system and ensure the heating effect of the indoor heater. [0003] In the existing technology, such...
