Problems solved by technology

[0003] In the actual operation and management of the air conditioning box, the set value of the air supply temperature is often set differently only in the transition season and the cooling season, and then the unreasonable adjustment of the set value of the air supply temperature leads to some problems under certain working conditions. Excessive energy supply (excessive cooling, excessive heating) or insufficient energy supply in the indoor environment

Abstract

The embodiment of the invention provides an air conditioning cabinet air supply temperature set value determining method and system based on algorithm prediction and a computer readable storage medium. The method comprises the steps that outdoor weather forecast data, date information and time information in a future time period are acquired and input into a trained air conditioning cabinet energy supply model, so that an air conditioning cabinet energy supply characterization value in the future time period is obtained; according to a preset fan operation frequency value, the air conditioning cabinet energy supply characterization value obtained through calculation and a preset algorithm, the air supply and return temperature difference is calculated and obtained; and an indoor target temperature value is obtained and serves as the air return temperature, the air supply temperature is calculated according to the air supply and return temperature difference, and therefore an air supply temperature set value is obtained. According to the method, the model which is determined by various influence factors is adopted to predict the air supply temperature set value in the future time period, and therefore the air supply temperature set value can be more accurately determined under different outdoor weather conditions.

Description

technical field [0001] The invention relates to the technical field of air conditioning system operation management, in particular to a method and device for determining a set value of air supply temperature of an air conditioning box based on algorithm prediction. Background technique [0002] In the existing building air-conditioning system, the common operation adjustment method of the air-conditioning box is to adjust the operating frequency of the fan according to the deviation between the return air temperature and the set value of the return air temperature, and to adjust the operating frequency according to the deviation between the supply air temperature and the set value of the supply air temperature. Adjustment of the water supply valve. In the operation and management of the air conditioning system, affected by the changes of various indoor and outdoor factors, the load demand of the air conditioning system is constantly changing. The air supply temperature sett...
