In the autumn of 1902, the inventor of air conditioning opened the train at Pittsburgh station. The temperature was only 30 degrees Fahrenheit, the station was covered with thick fog. At this point, the light in his brain came to light: as the formation of fog, if you can make the air saturated, and control its saturation temperature, you can get any desired humidity! And all this can be achieved by using nozzles to atomize the water, ultimately controlling the saturation temperature of the air by controlling the water temperature. In 1906 Dr Carrier obtained the patent of "Air Handling Unit." This is the world's first spray air processor, the function is to achieve humidification or dry air. In 1911, Dr Carrier presented his "Principles of Humidity and Humidity" to the American Society of Mechanical Engineers and gained the recognition of engineers as the most basic theory in the air conditioning industry. The School of Mechanical Manufacturing also teaches students air conditioning units made by Carrier as a course. This principle has been translated into various languages ​​and has become the basis of all air conditioning calculations today.
The theory of heat pumps originated in the writings of Carnot in the early nineteenth century. He published a paper on the Carnot cycle in 1824. Thirty years later, in the early 1850 Kelvin proposed that a refrigeration plant could be used to heat After that, many scientists and engineers conducted a lot of heat pump research, this study lasted for 80 years. In 1852, William Thomson published an essay that first proposed a heat pump concept. The first heat pump unit in Europe was built in 1938 with output of hot water up to 60oC. In the winter heat pump used for heating needs, can also be used in the summer cooling. The energy crisis in 1973 to promote the development of heat pump formed a climax. Since the 1970s, the heat pump industry has entered a golden age. Many countries in the world attach great importance to the research of heat pumps. For example, the International Energy Agency and the European Community have all made major plans for the development of heat pumps. New heat pump technologies are emerging, and heat pump applications are constantly being used Development, widely used in air conditioning and industrial fields, plays an important role in energy conservation and environmental protection. At present, Europe has highly developed heat pump theory and technology, this "double benefit" and environmentally friendly equipment in France, Germany, Japan, the United States and other developed countries have been widely used.
At that time, China's heat pump technology research and development work compared with foreign countries have a larger gap. In the 1950s, the Thermal Energy Research Institute of Tianjin University started to research the heat pump. Since the 1960s, the heat pump started to be applied in our country's industry. In 1965, Shanghai refrigerator factory successfully developed China's first heat pump window air conditioner, heating capacity of 3720W, the same year, Tianjin University and Tianjin Air Conditioner Factory successfully developed China's first water-cooled heat pump air conditioner, which is China's earliest water source Heat pump unit, the developer is Professor Lu Canren Tianjin University. Since then, research on heat pump has made rapid progress. By the 1980s, heat pump technology has been paid more and more attention to by people. However, heat pump products are mainly air source heat pump air conditioners and small and medium commercial air source heat pumps The main unit. After a long time test, solar water heaters and air heat pump are mature technologies, but the two are still not perfect combination of the current international heat pump products, heat pump hot air conditioner products simply can not solve and coordinate on the heat pump and air-conditioning operation Different working conditions, we can say that the existing hundreds of patents and hundreds of programs only saw or solved one or two or three problems at most. Even for some large companies and university research units of professional researchers to apply for the patent is the same situation. The reality is: hundreds of patents, hundreds of programs, but no one can eventually become a successful commercial product.
Until today, Snowknife heat pump hot water conditioner was successfully developed to solve this major problem. Successfully invented the true sense of the heat pump hot water air conditioner: 1, it uses Snow Nova solar thermostat hot water / water equipment, the international advanced technology, the use of the most advanced design, so that the full contact with the heat refrigerant and cold water, For heat exchange and cooling of working fluid, to maximize the heating efficiency of the cooling effect, the heat pump hot water air conditioner in energy output to maximize. 2, due to the cooling medium is good, reduce the load on the compressor, the heat pump hot water air conditioner running stable and reduce noise. 3, the water tank will not directly fill the cold water, so the water temperature is stable, always maintain a constant temperature. 4, according to local conditions, one machine or split installation. 5, due to the thermal efficiency of heat pump hot water air conditioner greatly improved, but also produce the current similar products (up to 60.C.) can not be achieved hot water or boiling water. It can not only provide conditions for a large number of concentrated use of hot water, but also because it is compatible with the daily heat capacity of the heat pump hot water air conditioner, which makes it feasible to start the free cooling of the heat pump hot water air conditioner, At the same time, the dual functions of heating water and cooling and heating make the coordination during the right to use, and fundamentally solve the serious defect of single cooling or heating of the current heat pump hot water air conditioner.
Snow Po heat pump hot air conditioner with heating and cooling of high efficiency, but also according to the habits of air-conditioning, compressor load, low noise, all-weather supply of hot water and other advanced features, it is currently other types of heat pump water heaters Technology is unmatched.
