Multi-split air conditioning system

Abstract

The invention discloses a multi-split air conditioning system. The system comprises an outdoor unit with an outdoor unit control module and a compressor, an indoor unit connected with the outdoor unit through a refrigerant pipeline, one or more water modules each provided with a water module control unit which is in communication connection with the outdoor unit, and a water module state detection module used for detecting the power failure state of the water modules and sending a detection signal to the outdoor unit control module, and the outdoor unit control module controls the compressor to be started and stopped according to the detection signal. According to the multi-split air conditioning system, the water module state detection module is arranged and used for detecting the power failure state of the water modules and sending the detection signal to the outdoor unit control module, and the outdoor unit control module directly controls the compressor to be started and stopped according to the detection signal. The situation that water in the water modules is cooled and frozen in a short time can be avoided, and the effect of protecting the water modules is achieved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a multi-connection system. Background technique [0002] In many places where central heating is not possible, more and more users use multi-connected air-conditioning systems to cool in summer and heat in winter. With the expansion of the water machine market, more and more users choose floor heating water systems for heating. hot. At present, the multi-connection with floor heating function has more complete functions than the combined supply of water, water, and water, and has certain advantages. The comfort of floor heating is gradually recognized by the market, and the advantages of fluoride and water are gradually becoming prominent. Connect the water module to realize floor heating. [0003] When the multi-split unit with floor heating function is connected to the water module to realize the floor heating function, if the water module suddenly loses power du...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the multi-connection system with water modules in the prior art cannot respond in time when the water module suddenly loses power, resulting in freezing of the water module and the entire system, the present invention provides a multi-connection system, which detects the water module In the power-off state, and directly send the detection signal to the outdoor unit control module to control the shutdown of the compressor and ensure the safety of the water module
