Description

This disclosure relates to an air conditioning control system that automatically controls the indoor environment to make it comfortable for occupants. Conventionally, in air conditioners, a comfort index called Predicted Mean Vote (PMV), which represents how people perceive temperature, has been proposed to achieve comfortable temperature sensations for inhabitants. Patent Document 1 describes an air conditioner that controls the air conditioner based on the PMV index, allowing the user to input their current temperature perception, verify their own operation, and perform precise corrections based on the PMV value to control heating and cooling as desired by the user.

The air conditioning control system according to an embodiment will be described in detail below with reference to the drawings. Embodiment 1. Figure 1 is a block diagram showing the system configuration of the air conditioning control system 1 according to Embodiment 1. The air conditioning control system 1 according to Embodiment 1 is a system that can automatically control air conditioning in order to achieve comfortable thermal comfort for the people living in the building. The air conditioning control system 1 according to Embodiment 1 comprises an air conditioner 100, a server 200, and an external control terminal 300. The air conditioner 100 has a function that automatically controls the air conditioning so that the indoor environment, which is the area to be air-conditioned by the air conditioner 100, is comfortable for the occupants, based on discomfort index information. The discomfort index information represents how people perceive temperature, and PMV (Percent-Morbidity Value) can be used. The air conditioner 100 comprises an indoor unit 110 installed indoors, an outdoor unit 120 installed outdoors, and a remote controller 130. The indoor unit 110 is capable of communicating with the outdoor unit 120 via a communication line (not shown). The remote controller 130 is an operating device that allows the user to set control commands for the air conditioner 100, and transmits the control commands operated by the user to the outdoor unit 120. Hereafter, the remote controller may be referred to as a remote control. The air conditioner 100, the server 200, and the external control terminal 300 are connected to each other via a global information and communication network such as the Internet 400, enabling them to communicate with one another. That is, the air conditioner 100, the server 200, and the external control terminal 300 are connected to a network and are capable of sending and receiving information from each other. However, each of the air conditioner 100, the server 200, and the external control terminal 300 may communicate directly with other devices in the air conditioning control system 1 without using the Internet 400. The air conditioner 100 forms a complete refrigeration cycle with the indoor unit 110 and the outdoor unit 120. The air conditioner 100 uses a refrigerant that circulates between the indoor unit 110 and the outdoor unit 120 through refrigerant pipes (not shown) to transfer heat between
