Problems solved by technology

[0003] In the related technology, the connection relationship between the signal control line and the connection pipe between the indoor unit and the outdoor unit has been one-to-one correspondence during the production of the one-to-many air conditioner, and cannot be changed. During installation, it is easy to wrongly connect the signal control line and the connecting pipe, so that the connection relationship between the signal control line and the connecting pipe between the outdoor unit and the indoor unit of the multi-air conditioner does not match, causing the refrigerant to flow to other indoor units In this way, the indoor unit that really needs to be refrigerated cannot perform cooling work. In this way, the signal control line and connecting pipe must be disassembled and the signal control line and connecting pipe must be reinstalled, which makes the installation of one-to-many air conditioners very troublesome and wasteful. time

Abstract

The invention provides a judgment method of a connecting relation between signal control lines of indoor and outdoor units and connecting pipes, a judgment device of the connecting relation between the signal control lines of the indoor and outdoor units and the connecting pipes and a multi-split air conditioner. The method comprises the steps: detecting the real-time temperature of an evaporator of any indoor unit after a refrigeration signal is sent to any indoor unit of a plurality of indoor units of the multi-split air conditioner; judging whether the real-time temperature of the evaporator of any indoor unit changes, when the real-time temperature of the evaporator of any indoor unit changes, the connecting relation between the signal control line between an outdoor unit and any indoor unit of the multi-split air conditioner and one connecting pipe is matched, and if the real-time temperature of the evaporator of any indoor unit does not change, the connecting relation between the signal control line between the outdoor unit and any indoor unit and the connecting pipe is not matched. Through the judgment method, the judgment device and the multi-split air conditioner of the technical scheme of the invention, in the condition that the outdoor unit and the indoor units are not removed, the control logic of output signals of the signal control lines is directly changed, so that the signal control lines and the connecting pipes are matched, so as to correctly control the indoor units.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a method for judging the connection relationship between indoor and outdoor unit signal control lines and connecting pipes, a device for judging the connection relationship between indoor and outdoor unit signal control lines and connecting pipes, and a Multiple air conditioners. Background technique [0002] At present, the number of indoor units of one-to-many air conditioners is at least two, and the number of indoor units of some one-to-many air conditioners is even five, six or more. When the indoor units are controlled to perform cooling work, the indoor The unit sends the control signal to the outdoor unit through the signal control line between the indoor unit and the outdoor unit. After receiving the control signal, the outdoor unit opens the regulating valve corresponding to the indoor unit, so that the refrigerant can flow through the regulating valve,...
