Consumer demand continues to upgrade and evolve, and the disadvantages of traditional Freon air conditioners with low comfort have been criticized by more and more consumers. We use advanced air source heat pump technology, with water as a medium that is more suitable for the human body, and heat by laying floor heating coils. The bottom-up heating method has a uniform temperature distribution and "warms the feet and cools the head", which is most in line with the "warm feet and cool the roof" advocated by Chinese medicine. Cooling by circulating cold water in summer is universally recognized. It is a better cooling method with a better temperature-to-humidity ratio. The cooling effect is significantly better than that of traditional air conditioners. It is refreshing, comfortable and not dry, effectively avoiding air-conditioning diseases.
