Problems solved by technology
[0002] When the air conditioning system operates in an environment with low outdoor temperature in winter, the evaporation temperature of the working fluid is very low, and the moisture in the air is easy to condense into frost on the surface of the evaporator, and frost is more likely to occur in areas with high air humidity phenomenon, and frost will increase the wind resistance of the outdoor unit, resulting in a decrease in the heat transfer coefficient of the heat exchanger
In order to solve this problem, the air-conditioning system usually needs to perform defrosting treatment, but when the existing air-conditioning system is running in the defrosting mode, it usually consumes part of the heat in the room, thereby reducing the room air temperature and affecting the heating process of the air-conditioning system. thermal comfort in the room

Embodiment Construction
[0034] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0035] Air conditioning system of the present invention, as figure 1 As shown, the air conditioning system includes: a processor 1001 , such as a CPU, a user interface 1002 , a memory 1003 , and a communication bus 1004 . Wherein, the communication bus 1004 is used to realize connection and communication between these components. The user interface 1002 may include a display screen (Display), an input unit such as a remote controller. The memory 1003 can be a high-speed RAM memory, or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1003 may also be a storage device independent of the foregoing processor 1001 .
[0036] The air conditioning system may also include an indoor unit, an outdoor unit, a compressor installed in the outdoor unit, and various sensors for detecting parame...

The invention discloses a defrosting control method of an air conditioning system. The method comprises the following steps: when a defrosting mode of the air conditioning system is operated, an outdoor environment temperature and a coil temperature of an outdoor heat exchanger are obtained; and a defrosting operation frequency of a compressor of the air conditioning system is dynamically adjusted according to the outdoor environment temperature and the coil temperature of the outdoor heat exchanger. The invention further discloses an air conditioning system and a computer readable storage medium. When the defrosting mode of the air conditioning system is operated, the operation frequency of the compressor is dynamically adjusted according to the outdoor environment temperature and the coil temperature of the outdoor heat exchanger, so that the defrosting time is shortened, and the heating comfort of the air conditioning system is improved.
Description
technical field [0001] The present invention relates to the technical field of air conditioning, in particular to an air conditioning system, a defrosting control method, and a computer-readable storage medium. Background technique [0002] When the air conditioning system operates in an environment with low outdoor temperature in winter, the evaporation temperature of the working medium is very low, and the moisture in the air is easy to condense into frost on the surface of the evaporator, and frost is more likely to occur in areas with high air humidity phenomenon, and frosting will increase the wind resistance of the outdoor unit, resulting in a decrease in the heat transfer coefficient of the heat exchanger. In order to solve this problem, the air-conditioning system usually needs defrosting treatment, but when the existing air-conditioning system is running in the defrosting mode, it usually consumes part of the heat in the room, thereby reducing the room air temperatu...
