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, 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. The 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 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. Air to water projects in most developed countries in Europe, 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 so is the use of heat pump water heater more common in the country. Overall, for the moment, foreign air source heat pump water heater market is already quite mature, the ratio used in developed countries, some as high as 70%, such as in Singapore, Europe and the United States in some countries and so on. Is in China's Hong Kong and Taiwan also have nearly 50% of the promotion of the use of force. Only affected by domestic consumption and economic development law guesthouse air to water engineering, air-source heat pump water heater is in the past four years to introduce and promote the use was only in a small area, and is concentrated in the economically developed two Delta. According to market statistics, although the product in the domestic market only a few years time, but the growth rate is very fast. In 2002, its sales of less than 10 million yuan, but by 2003, Shanxi air to water, it has reached 30 million yuan, in 2004 it reached 80000000-1 million in 2012 to break six billion yuan mark. You can say that the plant air to water projects, as the pace of development a few years ago when the Internet access, the entire industry sales growth will grow exponentially, a huge market space.
