AI Technical Summary
Technical Problem
The existing air conditioning system is prone to frosting when heating at low temperatures, and the air conditioning heating needs to be suspended to defrost, which affects the user experience.
Method used
An air conditioning system is designed, including two outdoor heat exchangers and control modules. By setting up a solenoid valve and a throttling device, the refrigerant does not need to be reversed during defrost. The first outdoor heat exchanger performs secondary condensation, and the second outdoor heat exchanger absorbs heat and defrost.
Benefits of technology
Defrost is achieved without stopping, avoiding somatosensory impairment caused by refrigerant reversal, and avoiding contradictions between high and low pressure pressure positions and defrost ability.

Abstract
The air conditioning system comprises a compressor, an indoor heat exchanger and an outdoor heat exchanger, the compressor, the indoor heat exchanger and the outdoor heat exchanger are connected through a four-way valve to form a refrigerant circulation loop, and the outdoor heat exchanger at least comprises a first outdoor heat exchanger and a second outdoor heat exchanger; a second outdoor heat exchanger; one end of the first outdoor heat exchanger is connected with the indoor heat exchanger, the other end of the first outdoor heat exchanger is connected with the second outdoor heat exchanger through an adapter, an electromagnetic valve is arranged in the adapter, two ends of the electromagnetic valve are connected with bypass pipes, and second throttling devices are arranged in the bypass pipes; and a first throttling device and a third throttling device are arranged in a pipeline between the first outdoor heat exchanger and the indoor heat exchanger. According to the air conditioning system, the refrigerant does not need to be reversed during defrosting, and strong body feeling difference cannot be caused to a user.
