Constant temperature control method, controller and control module of one-drag multi-air conditioner

Abstract

The present application relates to a constant temperature control method, controller and control module for one-to-multiple air conditioners. The method includes obtaining the return air temperature values ​​of the air supply areas of each air conditioner indoor unit, and determining the return air temperature among all the return air temperature values. The highest value and the lowest return air temperature; compare the lowest return air temperature and the highest return air temperature with the preset temperature; adjust the air conditioner corresponding to the lowest return air temperature and / or the highest return air temperature according to the comparison results The angle of the air deflector of the indoor unit is to keep the temperature of the return air in the air supply area of ​​each air-conditioning indoor unit of a multi-unit unit consistent. This application does not need to distinguish the main and auxiliary indoor units. Each indoor unit can independently detect the ambient temperature, which can realize the centralized control of one tractor and multiple units, and realize the consistency of temperature in different areas, and improve the air supply comfort of one tractor and multiple air conditioners. Make HVAC control more intelligent.

Description

technical field [0001] The present application relates to the technical field of air conditioners, in particular to a constant temperature control method, controller and control module for one-driver-multiple air conditioners. Background technique [0002] With the improvement of living standards, more and more places will install air conditioners to improve the comfort of work and life. For single large space occasions (such as small supermarkets, clothing stores, fast food restaurants, etc.), many of One for one air conditioner to meet the needs. In such places, the air conditioners are generally turned on and off at the same time. If multiple air conditioners with one drive and one air conditioner are adopted, centralized control cannot be realized; for the one drive with multiple units in the existing market, it is necessary to distinguish between the main and auxiliary indoor units, and the auxiliary indoor units follow the main If the indoor unit is running, the tempe...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the purpose of the present invention is to overcome the deficiencies of the prior art, and provide a constant temperature control method, controller and control module for one-drag multi-air conditioner, so as to solve the problem of distinguishing the main and auxiliary internal units of one-drag multi-air conditioner in the prior art. , the problem of poor air supply comfort and inconsistent temperature in different areas caused by opening and stopping at the same time
