A few days ago, a kind of using of a natural gas engine-driven gas-compression heat pumps successful development by Chunlan. This air-conditioning will be able to refrigeration, heating, hot water and provide health without any power, not only suitable for the ordinarily family who using the pipes or bottled natural gas (gas), but also suitable for the field sites, the regional power shortage and natural gas (gas) rich region.

With the improvement of the consumption levels, air-conditioning has become a necessity to enter millions of households, a huge amount of supply and demand in the community. However, air-conditioning as a large consumption of energy, and rely on the country's electrical energy infrastructure heavily, the development in the right direction or not, will have a direct impact on economic development, energy and regional air quality, and environmental protection. Therefore, the Ministry of Science and Technology will be "efficient and energy-saving technology for distributed", included in "'Eleventh Five' advanced energy technology field research and development topics", organized important research and technology research firms to focus on.

Since the second half of 2005, the Chunlan Institute on cooperation with Southeast University to form the group of gas-fired air-conditioning heat pump systems, fuel supply system, waste heat recovery system and data acquisition system for R & D and has successfully developed a prototype. By the relevant authority to identify, Chunlan air-conditioning heat pump gas products that meet the performance leader in the domestic level, not only to promote the natural gas engines, gas compressors then some number of key technology and development, but also for the power-saving air-conditioning, as well as clean and efficient energy development, conversion and using opened to a new way. At present, the air-conditioning has applied for four patents, and three of them have authorized.

It is reported that compare with the electricity air-conditioning, Chunlan' gas heat pump air-conditioning has prominent advantages: First, natural gas for clean energy, little harmful gases after combustion; Second, on the basis of the comprehensive functions, high-energy efficiency, an energy efficiency can be as high as 1.5 or more, 50% higher than the effect of energy-saving electric heat pump; Third, small vibration, low noise, small wear and tear, long life; Fourth, the application of environmentally refrigerants is no pollution; Fifth, the natural gas engine cooling water will be constantly heating by engine, thus during the rum-time, air-conditioning can provide clean water.

More importantly, after a wide range implementation and large-scale using of this air-conditioning, not only help to improve the tension of the domestic supply, promote comprehensive utilization of energy resources, reduce the waste of resources, and have significant economic and social benefits for improving the power load, improving the balance between the power peak and valley, gas seasonal peak and valley and so on.
