Can air be heated and cooled?

Of course. "Warm feet and cool the roof" is an effective way of health preservation advocated by Chinese medicine, and floor heating is the best national heating method in winter. Compared with the traditional heating method, the floor heating heat is continuously, slowly and evenly distributed indoors from bottom to top, which makes the body feel the layers of warmth in all directions. No hot air directly blows on the human body, which will not take away the water of the human body and make the body more moist. Air energy heat pump superconducting radiation heating system mainly absorbs a lot of heat energy in the air to generate heat, and then transmits it to the floor through a series of channel equipment, thus radiating indoors to achieve the purpose of indoor heating. Compared with other heating methods, this heating method is more energy-saving, comfortable and environmentally friendly. In summer, the cold air is blown by the fan coil unit, which is moist but not dry, far more comfortable than the dry cold air of air conditioning.
