Problems solved by technology

However, for commercial air-conditioning systems, there are multiple indoor units installed indoors. These indoor units are usually installed in the ceiling compartment. If R22 is replaced with R410A, the corresponding pipelines or components need to be changed, which obviously makes the operation very troublesome. , thereby degrading the user experience

Embodiment Construction

[0042] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] The present invention provides an air-conditioning system control method and an air-conditioning control system. When the refrigerant of the air-conditioning system is replaced and the air-conditioning system is in the heating mode, a temperature sensor is used to detect the temperature of the indoor heat exchanger regularly or in real time, and according to The detected temperature value is compared with the predetermined temperature value, and finally corresponding steps are executed according to the comparison result. In this way, under the premise of ensuring the normal operation of the air conditioning system, it is possible to avoid changing the corresponding pipelines or components of the air conditioning system, thereby reducing operation steps and greatly improving user experience.

Abstract

The invention discloses a control method of an air-conditioning system. The control method of the air-conditioning system includes the following steps: starting the heating mode of the air-conditioning system, and detecting the temperature of an indoor heat exchanger through a temperature sensor; judging the temperature of the indoor heat exchanger Whether the temperature is greater than or equal to the first predetermined temperature value; if so, control the fan speed of the outdoor unit, the opening and closing degree of the first electronic expansion valve of the indoor unit, and / or the opening and closing degree of the second electronic expansion valve of the outdoor unit to Decrease the pre-valve pressure of the first electronic expansion valve. The invention also discloses an air conditioner control system. When the refrigerant of the air-conditioning system is replaced, the present invention can avoid changing the corresponding pipelines or parts of the air-conditioning system under the premise of ensuring the normal operation of the air-conditioning system.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an air-conditioning system control method and an air-conditioning control system. Background technique [0002] Because refrigerant R22 is very harmful to the ozone layer, and R410A is a new type of environmentally friendly refrigerant that will not damage the ozone layer, and its working pressure is about 1.6 times that of ordinary R22 air conditioners, and the cooling (warming) efficiency is significantly improved. Therefore, the market The refrigerant of the air conditioner is gradually replaced by R22 to R410A. However, for commercial air conditioning systems, there are multiple indoor units installed indoors. These indoor units are usually installed in the ceiling compartment. If R22 is replaced with R410A, the corresponding pipelines or components need to be changed, which obviously leads to very troublesome operation. , thereby degrading the user experience. [000...
