[0002] Modern users have increasingly sophisticated requirements for the comfort of the indoor environment. They are no longer satisfied with simple "cold" or "hot", but pursue a comfortable experience with constant temperature, constant humidity, no wind, no noise, and evenly distributed temperature.
