Abstract

The invention discloses a variable-frequency multi-connected air conditioning unit self-adaptive control device. An outdoor unit control system comprises an air suction pressure sensor (1), an exhaust pressure sensor (2), six temperature sensors and an outdoor control panel, wherein each indoor unit control system comprises four temperature sensors, an expansion valve (16) and an indoor control panel. The invention also discloses a variable-frequency multi-connected air conditioning unit self-adaptive control method. The air suction pressure sensor (1), the exhaust pressure senor (2) and the six temperature sensors collect pressure parameters and temperature parameters of outdoor units for calculation, and after the four temperature sensors collect temperature signal parameters of the indoor units, and he self-adaptive regulation on indoor loads can be realized.

Description

technical field [0001] The invention relates to an adaptive control device and a control method of a frequency conversion multi-connection unit. Background technique [0002] There is a communication protocol between the indoor unit and the outdoor unit of the current frequency conversion multi-connected air conditioner unit. The outdoor unit controls multiple indoor units through the communication line, and the status of each indoor unit is also collected and transmitted through the communication line. to the main control board of the outdoor unit, and after the outdoor main control board judges and responds according to the operating parameters, it feeds back to the indoor unit. According to the current control method, a communication line must be installed for the indoor and outdoor units, which is inconvenient to install and complicated to control the whole unit. Contents of the invention [0003] The invention provides an adaptive control device and a control method ...
