Room temperature control method, room temperature control device, program, and room temperature control system

Abstract

This can suppress a decrease in room temperature during heating operation by an air conditioning system, even in an abnormal state where the heating function is substantially stopped. [Solution] The room temperature control method is a method for controlling the room temperature in a building having a room, an air conditioning system having a heating function for raising the room temperature, and a supply system that heats outside air present outside the room and supplies the outside air into the room, wherein it is determined whether an abnormal condition occurs in which the outlet temperature of the air blown into the room from the air conditioning system is below the room temperature during heating operation by the air conditioning system, and if it is determined that the abnormal condition has occurred, the heating temperature of the outside air supplied into the room by the supply system is determined based on the temperature difference between the room temperature and the outlet temperature of the air at a time set in advance from the time the abnormal condition was determined, and the supply system is operated based on the heating temperature.
