Abstract: The invention relates to the air environmental control technology field and discloses an environmental control unit including a shell, cooling device, a water pipe, a heating device, a control device, a sensor, a safety protection device, an air purification device and a humidifying device set in the shell. The invention combines the efficient circulation heating supply system with the air purification device. During the rapid heating of air, the cold-hot air convection is used to accelerate the air circulation purification and humidification treatment process. The sensor detects the real-time indoor air quality and adjusts the temperature, humidity and air quality by further control of the system according to the environmental parameters. The invention uses the air convection circulation to effectively improve the air purification and humidification efficiency with very high practical value. And it is of important positive significance for the development of water heating industry.
