Problems solved by technology

[0002] The operating environment of air conditioners in high-altitude areas is relatively special. The main performance is that with the increase of altitude, the atmospheric pressure and air density will be greatly reduced, and the mass flow rate of the heat exchanger inlet air will be greatly reduced, which will seriously affect the heat transfer performance of the air-side of the air-conditioning unit, resulting in Insufficient cooling capacity of air conditioner

Embodiment Construction

[0061] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the drawings in the embodiments of the present disclosure.

[0062] This disclosure detects natural environment information such as altitude information and weather information (such as solar radiation information, rainfall information, and wind speed information) where the air conditioner is located, and the operating load (such as condensing pressure (or high pressure) and evaporation pressure (or high pressure) of the air conditioning unit. Low pressure), pressure ratio), comprehensively consider the altitude information, weather information and operating load, and control the air conditioning unit (such as fan, compressor, electronic expansion valve). Various control modes are described in detail below.

[0063] figure 1 It is a schematic flowchart of an air conditioner control method based on altitude information according to so...

Abstract

The invention provides an air conditioning control method and device and an air conditioning system, and relates to the field of air conditioners. According to altitude information and condensation pressure information of the air conditioner, and in addition, in combination with weather information such as solar radiation, rainfall, wind speed and the like, the fan frequency of the air conditionercan be adjusted, so as to realize the scheme of controlling the air conditioner according to altitude factors or combined with weather factors.

Description

technical field [0001] The present disclosure relates to the field of air conditioning, in particular to an air conditioning control method and device and an air conditioning system. Background technique [0002] The operating environment of air conditioners in high-altitude areas is relatively special. The main performance is that with the increase of altitude, the atmospheric pressure and air density will be greatly reduced, and the mass flow rate of the heat exchanger inlet air will be greatly reduced, which will seriously affect the heat transfer performance of the air-side of the air-conditioning unit, resulting in Insufficient cooling capacity of the air conditioner. Contents of the invention [0003] In view of this, the present disclosure proposes a solution for controlling the air conditioner according to the altitude factor. In addition, the present disclosure also proposes a solution for controlling the air conditioner according to the altitude factor and combi...
