Embodiment Construction

[0026] In an embodiment of the present invention, a method for detecting communication connection errors of a heat recovery multi-connected air-conditioning system is provided, which includes steps S1-S3. Each will be described below.

[0027] Step S1: Determine whether the communication connection between the air conditioner unit and the pipeline control module is wrong by detecting whether the pipe temperature of the indoor unit is abnormal when the air conditioner unit is running, and mark the indoor unit with the wrong communication connection.

[0028] Among them, after the air-conditioning unit has been running for a period of time, the pipe temperature of each unit is detected, and the method for detecting whether the pipe temperature of the internal unit of the air-conditioning unit is abnormal is as follows:

[0029] When the control mode of the indoor unit is heating operation, if the inlet pipe temperature of the indoor unit is < system high pressure temperature -5°...

Abstract

The invention discloses a heat recovery multi-split air-conditioning system communication connection error detection method. The heat recovery multi-split air-conditioning system communication connection error detection method comprises the steps of 1, judging whether communication connection between an air conditioning unit and a pipeline control module is wrong or not by detecting whether the pipe temperatures of each indoor unit when the air conditioning unit operates is abnormal or not, and marking the indoor unit with wrong communication connection; and 2, switching the control mode of the indoor unit, and finding the indoor unit with the pipe temperature varying with the control mode correspondingly from all the other indoor units, wherein the found indoor unit is the indoor unit which is actually controlled through the pipeline control module remaining communication connection with the marked indoor unit. By means of the detection method, the communication connection error can be detected in time. The invention further discloses a heat recovery multi-split air-conditioning system.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a method for detecting communication connection errors of a heat recovery multi-connection air conditioning system and a heat recovery multi-connection system. Background technique [0002] The heat recovery multi-connected air conditioning system is a multi-connected system that can realize part of the internal cooling and part of the internal heating at the same time. Such as figure 1 As shown, the heat recovery on-line air conditioning system controls the air pipe of the internal unit to connect with the high-pressure air pipe or low-pressure air pipe of the external unit through the mode converter to realize the operation of the internal unit in different modes. When the heat recovery multi-connected air conditioning system is installed, multiple pipeline control modules are integrated in the mode converter, which are used to control the state of the solenoid valve in the pip...
