Trace its origin, air heaters should be regarded as exotic. Air source heat pump technology in 1924 had been the invention abroad. However, has not been fully recognized and utilized humans in a very long period of time. Until the 1960s, after the world's energy crisis will be subject to full attention to community pool air source hot water units, so the world since then have increased R & D efforts to further promote the heat pump technology, making the current heat pump technology has been more widely used . The early 1970s, due to the "energy crisis" appeared school pool air source water heaters, heat pumps also its low waste heat recovery air source water heaters, energy-saving features in the product after the improvements, but also by the people favor. Such as the US, the heat pump output from 8.2 million units in 1971 / year in 1976 soared to 30 million units / year, again in 1977 jumped to 500,000 units / year, but this time from behind Japan, the annual output more than 500,000 sets. Heat pump market is currently doubling every year, very rapid development momentum. In Europe and most developed countries, such as Australia, Britain, France, Scandinavia and southern Europe, some countries, heat pump products have entered the majority of families, and in our neighboring countries such as Singapore, Malaysia and other heat pump water heater is more common country. It is understood that air heating and heat pump heating capacity will decrease as the ambient temperature gradually decay, when the ambient temperature is below -10 ℃, the conventional air heater heating capacity is difficult to meet the needs of users. As a "Chinese polar expedition special products" Niuen Tai air heating pump, using a liquid jet enthalpy Shanxi pool technology air source hot water units, completely solve the traditional low cryogenic air heat pump heating poor reliability and energy efficiency problem. Niuen Tai cryogenic air heating heat pump can operate reliably -20 ℃ ambient temperature, especially for the Yellow River Basin, North China (including Beijing area), Northwest Territories, greatly improving the application of the regional air heat pump for heating. Niuen Tai air heating pump with excellent quality polar, won the majority of consumers, sales increased rapidly.
