Method for determining pre-cooling time of building by using intelligent control algorithm with neural network model

The present invention provides an intelligent control algorithm using a neural network model to control the air conditioning facilities by using an intelligent control algorithm using a neural network model, thereby maintaining the interior of the building in a comfortable environment and saving energy used for the air conditioning. An object of the present invention is to provide a method of controlling pre-cooling of a used building. The reservation cooling control method of a building using an intelligent control algorithm based on a neural network model according to the present invention includes learning the indoor temperature, the indoor temperature gradient, the outdoor temperature, and the outdoor temperature gradient as input variables and precooling time as output variables. Importing the adapted neural network model; Measuring a measurement variable including the indoor temperature and the outside temperature at a set time interval; Calculating a calculation variable including the indoor temperature slope and the outside temperature slope from the measured variable; Calculating the precooling time at a measurement time point by inputting the input variable to the neural network model; And calculating a difference between the precooling time and a target setting time and performing an operation according to a set operating procedure when the difference is within a setting value.
