Adjusting method and device for preventing misconnection of double-system air conditioner connecting pipes and air conditioner

Abstract

The invention relates to an adjusting method and device for preventing misconnection of double-system air conditioner connecting pipes and an air conditioner. The air conditioner comprises a first air conditioning system and a second air conditioning system, the first air conditioning system comprises a first outdoor unit and a first indoor unit, and the second air conditioning system comprises a second outdoor unit and a second indoor unit. The adjusting method comprises the steps that the first air conditioning system is started, after the preset time is achieved, an absolute value of T<inner ring>-T<first inner pipe> and an absolute value of T<inner ring>-T<second inner pipe> are compared with deltat DEG C, whether the connecting pipes of the first air conditioning system and the second air conditioning system are misconnected or not is judged according to comparative results, and the connecting pipes are reconnected and adjusted under the condition of connecting pipe misconnection, wherein T<inner ring> represents the indoor environment temperature, T<first inner pipe> represents the temperature in a heat exchanger pipe of the first indoor unit, T<second inner pipe> represents the temperature in a heat exchanger pipe of the second indoor unit, and deltat DEG C represents a preset temperature value. According to the method and device, whether the connecting pipes are misconnected or not and the misconnection mode can be quickly judged, and then reconnection and adjustment can be conveniently conducted.

Description

technical field [0001] The invention relates to the field of air conditioning systems, in particular to a debugging method and device for preventing wrong connection of connecting pipes of a dual-system air conditioner, and an air conditioner. Background technique [0002] Air-cooled unitary air-conditioning units are highly competitive products with extremely high requirements for cost control. For some cooling models with small demand, a dual-system design is usually adopted, that is, the internal and external units are divided into two, and the dual systems are independent of each other. For example, for a ten-horsepower cabinet unit, two five-horsepower compressors are used for the external unit, which are divided into two and share a fan. Originally, the demand for 5-hp compressors was large, but in terms of price, two 5-hp compressors are cheaper than one 10-hp compressor, and the use of 10-hp compressors can further increase the demand for 5-hp compressors, thereby r...
