Problems solved by technology

[0004] Therefore, an object of the present invention is to propose a new mode control method for a multi-connected system, which can solve the problem of frequent start-stop damage to the external unit caused by frequent switching of the multi-connected system mode in the case of relatively large ambient temperature fluctuations. Compressor problem, at the same time, set different mode switching temperature thresholds according to different ambient temperatures, so as to effectively avoid the situation that the internal machine is cooling and blowing cold air when the weather is cold, and the internal machine is heating and blowing hot air when the weather is hot, and ensures that the multi-connected system is in the air. Operate at the optimal temperature point set by the user, thereby improving the user's comfort experience

Abstract

The invention provides a VRF air conditioning system as well as a mode control method and device thereof and a storage medium. The mode control method comprises the following steps of: obtaining a current first indoor environment temperature, a set temperature and a preset return difference temperature of the VRF air conditioning system; determining an initial operation mode of the VRF air conditioning system according to the first indoor environment temperature, the set temperature and the preset return difference temperature; after the VRF air conditioning system works according to the initial operation mode, obtaining a real-time temperature difference value between the second indoor environment temperature and the set temperature; and controlling the VRF air conditioning system to switch an operation mode according to a preset temperature threshold value range in which the temperature difference value is included. According to the technical scheme adopted by the invention, a compressor can be prevented from being damaged by frequent switching of the mode of the VRF air conditioning system; and meanwhile, a condition that an inner unit refrigerates to blow cold air in a cold dayand the inner unit heats to blow hot air in a hot day is avoided, and comfort experience of a user is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of air conditioning systems, in particular, to a mode control method for a multi-connection system, a mode control device for a multi-connection system, a computer-readable storage medium, and a multi-connection system. Background technique [0002] At present, in the general volume control multi-connected air conditioning system, the automatic mode of the indoor unit can only be switched between air supply and cooling or air supply and heating. The three-control multi-connected system can realize the automatic mode of the indoor unit in cooling and heating modes Switching, and the general three-pipe automatic mode control, in the case of relatively large ambient temperature fluctuations, it is easy to cause frequent switching between modes, resulting in frequent start and stop of the outdoor unit and damage to the compressor, and if the automatic mode is set in winter In this mode, the cold air blow...
