Abstract

Provided are a method for controlling a multi-split air conditioner, and a system for controlling the multi-split air conditioner. The multi-split air conditioner comprises a new air indoor unit (3). The method for controlling the multi-split air conditioner comprises the following steps: S1: measuring an outlet air temperature of the new air indoor unit (3), an outdoor environmental temperature, a system pressure of the multi-split air conditioner, and air intake and discharge temperatures of a compressor (5) of the multi-split air conditioner all of which are used as control parameters; and S2: based on the capacity condition of the multi-split air conditioner and the measured outdoor environmental temperature condition, controlling capability output of the multi-split air conditioner according to the system pressure or the air outlet temperature. By using the technical solutions of the present invention, the effective operation of the multi-split air conditioner integrating a new fan and an ordinary indoor unit is ensured under the control of the control system, while the comfort and the reliability are considered.

Description

technical field [0001] The present invention relates to the field of air conditioners, in particular to a method for controlling a multi-connected air conditioner and a control system for a multi-connected air conditioner. Background technique [0002] Compared with other air conditioning systems, the biggest difference between the multi-split system is that one system can have multiple outdoor units and multiple indoor units, and it can be matched with different forms and types of indoor units. With the continuous improvement of people's requirements for the cleanliness of air conditioners, the use of fresh air conditioners has become more and more a trend. The fresh air air conditioner is characterized by the design that the outdoor side is connected to the air return port, which can directly introduce the outdoor air into the indoor side after treatment to provide a healthy air environment for the indoor environment. Its operating conditions are quite different from ordin...
