An intelligent control method for air conditioning temperature control and heating

Abstract

The invention provides an intelligent control method for air conditioner temperature control and heating. The intelligent control method comprises the steps that when it is detected that the environment temperature Th is lower than the preset first temperature, and the value of the condensation side outlet water temperature Tc is smaller than or equal to the difference value between the preset temperature Ts and the preset second temperature, the next step is started; whether the rate of water flow in an air conditioning system reaches the set value or not is detected, if yes, first-stage heating is started, and if not, heating is not started; and when it is detected that an air conditioning unit stops due to failure, and first-stage heating is started, second-stage heating is started. According to the intelligent control method, the heating process is efficiently and intelligently controlled by arranging first-stage heating and second-stage heating, thus, the water temperature is notsubstantially changed, first-stage heating is used for controlling and adjusting the water temperature to be kept within the normal range, second-stage heating can accelerate the heating process, andthus, an air conditioner still can operate normally under the quite cold condition; and first-stage heating is adopted under the common condition, first-stage heating and second-stage heating are adopted for being operated simultaneously when the freezing degree is high, resources can be saved, and the temperature can be controlled more intelligently.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an intelligent control method for temperature control and heating of an air conditioner. Background technique [0002] At present, air conditioners are prone to freezing and other freezing phenomena in winter, and because of the cold winter, air conditioners will be affected to varying degrees. For example, the following questions: [0003] 1. In terms of heating capacity and energy efficiency: most of the air conditioners on the market at this stage operate at a nominal minimum temperature of -12°C. When the ambient temperature (Th) continues to drop, the capacity and energy efficiency of the air conditioner will decay rapidly. For example, when the environment When the temperature drops to -16°C, the heating capacity will be reduced by 30%. When the ambient temperature drops to -25°C, the heating capacity will be reduced by 50%. When the ambient temperature continue...
