Document Type and Number:
WIPO Patent Application WO/2019/153797
Kind Code:
A1
Abstract:
An outdoor unit heat exchanger (100) matching method and an outdoor unit. An outdoor unit heat exchanger (100) comprises a plurality of sets of refrigerant flow paths connected in parallel, and each set of the refrigerant flow paths comprises a plurality of rows of refrigerant pipes connected in series and a controllable switch member for controlling whether refrigerants flows through the refrigerant pipes. The outdoor unit heat exchanger (100) matching method comprises the steps of: controlling an air conditioner to operate in a cooling mode or a heating mode; obtaining the indoor unit coil temperature and the compressor discharge temperature in real time, and determining a switching state of the controllable switch member according to a known matching relationship; and determining, according to the switching state of the controllable switch member, the number of the refrigerant flow paths that allow the refrigerants to flow through, and determining the number of the refrigerant flow paths that allow the refrigerants to flow through and the switching state of the controllable switch member as those of the outdoor unit heat exchanger (100) matching the indoor unit. According to the method of the present invention, an outdoor unit can match different types of indoor units, and the problem in the prior art that an outdoor unit needs to be replaced when the indoor unit type is replaced is solved.
