The air source heat pump utilizes the infinite energy contained in the air. In summer, the indoor heat flows to a higher temperature outdoor to cool the room. In winter, the heat in the outdoor air can be used to heat the room. Since the central refrigeration air conditioner has real cooling and heating heat from the outdoor air, it does not require a cooling water system during summer cooling, so the operating cost is very economical, and a large amount of water resources can be saved, and at the same time, no pollutants are generated when the system works. Very consistent with China's energy conservation and environmental protection trends and policies.
However, for a long time, ordinary air source heat pump central air conditioners can only be applied in the middle and lower reaches of the Yangtze River, southwest and south China, but not in the northern regions in winter. In 1996, the air source heat pump was technically improved. The unique technology of the Fenix ​​(PHNIX) unit effectively solved the problem of incomplete defrosting, making it successful in the Yangtze River Basin and the Yellow River Basin with a minimum temperature of -8 °C in winter.
After two years of painstaking research, Fenix ​​(PHNIX) has tapped the potential of the heat pump system to the maximum, and once again launched the world's only "North Star series" low-temperature air source heat pump unit that achieves -25 °C heating, Fenix ​​(PHNIX) air source heat pump The application of breakthrough limits to North China, especially in Tibet, has completely changed the history of long-term use of coal and gas heating in the northern regions and high altitude climates in Tibet, and has played a positive role in improving the environment and saving energy.
