The real five constant systems are constant temperature, constant humidity, constant oxygen, constant cleanliness and constant static.
The five constant systems are aimed at temperature, humidity, PM2.5, oxygen balance and noise.
Treat it, control it in the best range suitable for human body, and let comfort form naturally.
Five constant systems are integrated into the building itself. Capillary tubes laid in the ceiling take cold water in summer and hot water in winter to keep the temperature of water indoors through low temperature radiation. This temperature is not like the cold air of air conditioner blowing directly, which gives the human body a strong cold stimulus. The body feels very comfortable and natural, there is no wind and no noise.
Ground fresh air is sent into the room after precooling or preheating, dust removal and dehumidification. Because of the low wind speed and low temperature, it slowly accumulates on the ground, squeezing the polluted air in the room to rise, and then discharging it from the air outlet at the top of the kitchen and bathroom. The air circulates outside, and the indoor air is completely replaced every hour. As silent as human breath, the indoor air is fresh, clean and refreshing.
