A method for controlling cooling operation of an air conditioner

Abstract

The invention discloses an air conditioner refrigeration running control method. The method includes the steps that the actual running refrigerating capacity of an air conditioner within a set time period and the actual temperature change of a room where the air conditioner is located are obtained; the reference temperature change corresponding to the actual refrigerating capacity is determined according to the actual refrigerating capacity and the corresponding relation between the known refrigerating capacity and reference temperature change; and target parameters are determined according to comparison results of the actual temperature change and the reference temperature change corresponding to the actual refrigerating capacity, and the air conditioner is controlled to run according to the target parameters. The actual refrigerating capacity is determined according to the real-time press frequency, the real-time indoor temperature, the real-time outdoor temperature, the real-time indoor unit rotating speed, the real-time outdoor unit rotating speed and the real-time running power. By means of the method, the control performance of the air conditioner can be improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a cooling operation control method of an air conditioner. Background technique [0002] When the air conditioner is working, it operates according to the target parameters, and adjusts the room temperature, humidity, etc., so that the room environment meets the comfort requirements. [0003] For the parameter value of the target parameter of the air conditioner, one case is the system recommended parameter value placed in the air conditioner, or the parameter value calculated according to the system recommended parameter value; the other case is the parameter value set by the user , or the parameter value calculated according to the parameter value set by the user. For the first case, if the parameter value is a system recommended parameter value or a parameter value calculated according to the system recommended parameter value, the system recommended param...

AI Technical Summary

Problems solved by technology

However, when the air conditioner is actually used, the conditions will change, and almost none of them are standard conditions. Therefore, the system recommended parameter values ​​are not necessarily appropriate values, and the room environment comfort obtained based on the system recommended parameter values ​​is poor.

For the second case, if the parameter value is set by the user or calculated according to the user's setting, since the user generally does not understand the performance of the air conditioner and the matching environment, there will often be differences in the air conditioner due to different environmental conditions. The target parameters cannot be achieved, resulting in poor room environment comfort; or the air conditioner cannot achieve the target parameters more reasonably, resulting in poor air conditioner performance
