てしまいェネルギの浪費となっていた。When using a room in a building, etc., in the conventional method of installing a room conditioner, the precooling and secondary heat loads are set to fixed values throughout the year, so if the actually required precooling and secondary heat loads are smaller than the fixed values. In this case, the temperature reaches the room temperature before the room can be used, resulting in a waste of energy.

なう方法を提供することにある。In addition, on extremely hot or cold days, the required precooling and preheating loads will be larger than the fixed value, so even when it is time to start using the room, the indoor temperature may be higher or lower than the indoor setting temperature, causing the indoor environment to deteriorate. had the disadvantage that it could not be kept at the maximum temperature. In other words, in the conventional method, there is no distinction between summer, winter, and intermediate seasons, so it is not possible to respond to seasonal changes. There is a program called the dynamic heat load calculation method that calculates accurate precooling and secondary heat loads to maintain the indoor temperature at the set temperature during indoor use, but this program requires complex calculations and takes time to process. be. An object of the present invention is to provide an extremely simple method for efficiently performing pre-cooling and sub-heating based on actual measurement data (indoor temperature) in order to maintain the required indoor temperature at the start of room use.
