Control method of air conditioning system

Abstract

The invention belongs to the technical field of heat exchange equipment, and particularly relates to a control method of an air conditioning system. The method aims at solving the problem that a way of determining an indoor temperature regulating demand by existing air conditioning equipment is inaccurate and thus, the initial opening degree of an electronic expansion value determined is not matched with an actual operating requirement of air conditioning equipment. In order to achieve the purpose, according to the control method of the air conditioning system, the room can be divided into the multiple areas, a room load is calculated based on the initial environment temperatures of the multiple areas, the load size of each area in the room is refined, and the room load value corresponding to the whole room is accurately calculated; the difference between the current temperature condition and the expected temperature condition of the room can be accurately determined on the basis of the difference between the room load value and the preset load value, and the determination accuracy of the temperature regulation requirement in the room is improved, so that the actual operation requirement of the air conditioning system can be more accurately obtained, and the initial opening degree of the electronic expansion valve is better matched with the actual operation requirement of the air conditioning system.

Description

technical field [0001] The invention belongs to the technical field of heat exchange equipment, and in particular relates to a control method of an air conditioning system. Background technique [0002] In order to maintain a comfortable ambient temperature, air-conditioning equipment has become an indispensable household appliance in people's lives, such as household air-conditioning equipment in residents' homes and multi-connected air-conditioning equipment in large places such as hotels, office buildings, and shopping malls. Specifically, the air conditioner includes an indoor heat exchange part composed of at least one indoor unit, an outdoor heat exchange part composed of at least one outdoor unit, and a refrigerant transport pipeline connected between the indoor heat exchange part and the outdoor heat exchange part, The refrigerant transportation pipeline can form a loop between the indoor heat exchange part and the outdoor heat exchange part, so that the refrigerant ...
