Title:
ECONOMIZER OPENING TEMPERATURE DETERMINATION METHOD AND DETERMINATION DEVICE, AND AIR CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/183726
Kind Code:
A1
Abstract:
The present application provides an economizer opening temperature determination method and determination device, and an air conditioning system. The economizer comprises: a plurality of openings and a heat exchange flow channel formed inside the economizer, and the plurality of openings comprises a plurality of first openings and a second opening. The economizer opening temperature determination method comprises: acquiring opening temperatures of a plurality of first openings; determining flow parameters of a heat exchange flow channel; and determining the opening temperature of a second opening according to the opening temperatures of the plurality of first openings and the flow parameters of the heat exchange flow channel. The economizer opening temperature determination method and determination device, and the air conditioning system of the present application solve the problems of a large number of physical temperature sensors for measurement of the openings of the economizer and a high probability of failure of the air conditioning system, and can reduce the number of physical temperature sensors, simplify the mechanical structure and device assembly process, and lower the cost.
