Problems solved by technology

During the defrosting process, due to the reversing of the four-way valve, the temperature of the indoor air supply drops, thereby reducing the indoor comfort.
The traditional hot gas bypass defrosting technology directly bypasses part of the high-temperature and high-pressure steam to the outdoor heat exchanger for defrosting, and then directly enters the air return port of the compressor. This defrosting method will cause a relatively high suction and discharge pressure of the compressor. Great changes, while reducing indoor user experience

Abstract

The invention discloses an air conditioning system and an air conditioner with the same. The air conditioning system comprises a compressor, a reversing valve, an indoor heat exchanger, a first outdoor heat exchanger and a second outdoor heat exchanger. The compressor is provided with an exhaust outlet and a return air inlet. The reversing valve is provided with a first port, a second port, a third port and a fourth port, wherein the first port is communicated with the return air inlet, and the fourth port is communicated with the exhaust outlet. The first end of the first indoor heat exchanger is connected with the third port. The first outdoor heat exchanger and the second outdoor heat exchanger are adjacently arranged; the first end and the second end of the first outdoor heat exchanger are communicated with the second port and the second end of the indoor heat exchanger respectively, the first end of the second outdoor heat exchanger is communicated with the exhaust outlet, and the second end of the second outdoor heat exchanger is communicated with the second end of the first outdoor heat exchanger. According to the air conditioning system, not only can the heating effect be achieved, but also frosting of the first outdoor heat exchanger can be avoided, and the defrosting effect is achieved; and the air conditioning system is simple in structure, good in defrosting effect and high in combination property.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, and more specifically, relates to an air conditioning system and an air conditioner having the same. Background technique [0002] The defrosting method generally adopted by air conditioners in the related art is four-way valve reversing defrosting. During the defrosting process, due to the reversing of the four-way valve, the temperature of the indoor air supply drops, thereby reducing the indoor comfort. The traditional hot gas bypass defrosting technology directly bypasses part of the high-temperature and high-pressure steam to the outdoor heat exchanger for defrosting, and then directly enters the air return port of the compressor. This defrosting method will cause a relatively high suction and discharge pressure of the compressor. Big changes will reduce the indoor user experience at the same time. Contents of the invention [0003] The present invention aims to solve on...
