Residential air to water engineering, Taiyuan hundred Spirit through (certified, Taiyuan air to water projects provided by the Spirit through Taiyuan hundred Refrigeration Equipment Co., Taiyuan hundred Spirit through Refrigeration Equipment Co., Ltd. (www.sxkqn.com) is specialized in "air-source heat pump, central air conditioning, stainless steel water tanks, air curtain" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services are welcome to inquire Contact:! Zhang . trace its origins, air heaters should be regarded as an exotic air source heat pump technology in 1924 had foreign invention, however, and has not been fully recognized and utilized humans in a very long period of time. Until the 1960s, the World After the energy crisis will be subject to full attention residential air to water projects, so since then the world have increased R & D efforts to further promote the heat pump technology, making the current heat pump technology has been more widely used .20 early 1970s, due to The "energy crisis", low temperature waste heat recovery heat pump but also for its energy-saving features in the product after the improvements, but also by people of all ages, such as the United States, the heat pump's output from 1971 to 82000 units / year surge 1976 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 units. Currently heat pump market 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. heating air to enter the north, to replace the traditional heating plant air to water projects, the key is to overcome the energy efficiency by industry advanced technology, into the North is no serious problem with the hotel air to water projects, but get rid of it in the past, "beat the heat pump cold "backward understanding air to water projects, but also a necessary condition for air heating can be universal. In September, Niuen Tai and the State Oceanic Administration's Office of Polar expedition reached cooperation, and air to product delivery to Antarctica, Antarctic expedition to provide hot water, heating and other services. This not only witnessed its exquisite technology and high quality products, but also fundamentally splintered people "cold heat" error awareness, accelerate air heating in northern popularity.
