Abstract

Embodiments of the present invention provide a control method and an indoor unit for a multi-connected air-conditioning system, so as to at least solve the problem in the prior art that the multi-connected air-conditioning system cannot be remotely and centrally controlled. The method includes: acquiring the electrical signal of the nth cycle output by the digital controller, the electrical signal of the nth cycle is determined by the digital controller according to the temperature input by the user and the temperature of the environment where the indoor unit is detected in the nth cycle; The electrical signal of the nth cycle and the corresponding relationship between the electrical signal and the inhalation temperature stored in advance determine the inhalation temperature corresponding to the electrical signal of the nth cycle; according to the inhalation temperature corresponding to the electrical signal of the nth cycle, obtain the nth cycle The target frequency correction coefficient of the nth cycle; the target frequency correction coefficient of the nth cycle is sent to the outdoor unit in the multi-connected air conditioning system, and the outdoor unit adjusts the operating frequency of the outdoor unit compressor according to the target frequency correction coefficient of the nth cycle Make corrections. The invention is suitable for the technical field of air conditioning.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a control method and an indoor unit of a multi-connected air conditioning system. Background technique [0002] With the improvement of people's living standards, the requirements for the heating / cooling performance of air conditioners are also getting higher and higher. Typically, an important factor affecting the heating / cooling performance of an air conditioning system is the compressor in the system. [0003] In the prior art, for a modular multi-connected air-conditioning system, the operating frequency of the compressor of the air-conditioning outdoor unit in the system is usually controlled by the return air temperature. That is, after the user sets the desired temperature, the central processing unit (Central Processing Unit, CPU for short) inside the air conditioner indoor unit in the system will adjust the compression of the air conditioner outdoor unit in the...
