Embodiment 1
[0030] The room temperature estimating device 10 of the present embodiment is configured to estimate the room temperature on the date and time of interest from the outside air temperature based on a prediction formula that correlates the outside air temperature and the room temperature. Therefore, the room temperature estimating device 10 includes a structure configured to generate a prediction formula and a structure configured to estimate the room temperature from the outside air temperature based on the prediction formula.
[0031] The room temperature estimating device 10 includes, as main hardware components, a device including a processor configured to execute a program to realize functions described below and a device for an interface. A device including a processor may be a microcomputer having a built-in memory, a processor mounted with an external memory, or the like. Also, a computer that executes a program to realize the functions described below can be used as the...
Embodiment 2
[0065] In Embodiment 1, the prediction formula generating unit 15 generates prediction formulas each based on the room temperature and the outside air temperature measured in the time zone in which the room temperature is not affected by sunlight. Therefore, the time zone in which the prediction formula can be applied to estimate the room temperature from the outside air temperature is limited. In other words, based on the prediction formula generated according to Embodiment 1, the room temperature in the time zone in which the room temperature is affected by sunlight cannot be accurately estimated. The prediction formula according to Embodiment 1 can be applied only to a time zone in which the change of the outside air temperature is relatively moderate, such as the time period from midnight to early morning.
[0066] In this embodiment, a technique for determining a prediction formula suitable for a daytime time zone in which room temperature is affected by sunlight is descr...
Embodiment 3
[0092]In Embodiment 1 and Embodiment 2, the room temperature estimating device 10 is configured to estimate the room temperature based only on the outside air temperature. However, as mentioned above, in the absence of cooling and heating, the room temperature depends on factors including sunlight, ventilation, rainfall, and the number of people in the room. Note that if cooling and heating is performed using a cooling and heating device with a function of controlling the room temperature, the temperature in the room depends on the operating state of the cooling and heating device, so the room temperature cannot be predicted by the prediction formula. Therefore, in the following description, it is assumed that cooling and heating are not performed.
[0093] In order to consider information of insolation, ventilation, rainfall, and existing number of people in addition to the outside air temperature, creation of a model for associating each information with room temperature is ...
