AI-Enhanced Air Conditioner That "Grows" by Learning User Preferences—Automatically Adjusts Room Temperature to Match User's Lifestyle

AI Is Becoming Part of Our Everyday Lives

Artificial intelligence is increasingly becoming a part of our daily living. Many of you have seen a scene on TV where a person talking to a smart speaker on the kitchen table gets a recipe or orders ingredients online. AI is not only incorporated into information devices but also home appliances as well. One example is the AI-enhanced air conditioner, the nocria X series, developed by the Fujitsu Group.

This is a product that integrates air conditioner development know-how that Fujitsu General has obtained over many years and the technologies for FUJITSU Human Centric AI Zinrai ("Zinrai") that have been studied for over 30 years at Fujitsu Laboratories.

What happens when an air conditioner is equipped with AI?
In the past, there were air conditioners that could automatically optimize the temperature for the room environment. However, while many were able to set the temperature to the level where people usually felt comfortable, they were unable to optimize room temperatures in accordance with users' temperature preferences or the required cooling/heating capacity, which varies with the room frame -whether it be wooden or steel- and room size.

The AI-enhanced air conditioner developed by Fujitsu General, on the other hand, uses AI to learn the building quality for the room and temperature preferences of the room users. Therefore, each unit learns its environment and predicts and sets the temperature preferred by room users for comfort.

Auto-Temperature Adjustment Feature Matches Preferences of People in the Room

How fast a room becomes warm or cool varies with not only the building structure between wooden and steel but also the intensity of sunlight that enters the room. The AI-enhanced air conditioner continuously learns from daily operations the frequently used room temperature settings and the room environment for the user household. More specifically, when the user changes the temperature setting thinking "It's a bit hot" or "It's a bit cold," AI learns how the setting gets changed as well as the temperature, humidity and time of such change. It collects and accumulates such data to generate a learning model for predicting the optimal control for each household. Fujitsu's AI Zinrai accumulates data and generates a learning model.

Then, the microcomputer embedded in the air conditioner refers to the learning model sent from Zinrai and also the latest environmental data such as temperature, humidity and time. It predicts users' device operations and automatically changes or adjusts the temperature setting. As a result, the product provides "a comfortable space" without the user in the room noticing it.

Zinrai generates a learning model, and the microcomputer embedded in the air conditioner predicts device operations of the user. Such division of roles allows the Fujitsu General AI-enhanced air conditioner to provide optimal control with a high degree of accuracy and responses.

Scope of the service

AI "Grows" Each Time the Air Conditioner Is Used

The AI-enhanced air conditioner works with weather forecasts. It sends a timer operation notification to the user's smartphone when the next morning is expected to be very cold or when the temperature is expected to stay above 25°C throughout the night. When the user activates the timer, the product calculates the best time to turn itself on based on the room structure and size learned by the AI and controls the temperature to achieve the set temperature at the selected time. With such AI, the product is engineered to provide comfort tailored to each household while minimizing electricity use.

Furthermore, AI collects various types of data while the device is operating to learn household-specific lifestyles. The resulting learning model is used to produce an even more comfortable indoor environment. The device including the AI features is updated via the internet, allowing both AI and the air conditioner to "grow." With these features, the product achieves not only comfort but also saves energy in line with the operating environment and conditions.

The Fujitsu AI Zinrai has a feature to work with a wide variety of applications and services. It is believed that AI technology will be increasingly incorporated into systems and products that we use in our everyday lives.

This AI-enhanced air conditioner is the first case that achieved collaboration between Zinrai and a consumer device that many people use daily. Going forward, collaboration between home appliances, consumer devices and Zinrai will gain even more momentum, and AI-enhanced home appliances will be the center of our lives in smart houses.
