At present, the construction of a central air-conditioning of commercial buildings generally exist the problem of high energy consumption, such as the Tsinghua University in 1998 in Beijing City, ten business good shopping mall to conduct a comprehensive testing and statistics, the average annual energy consumption of these stores is about 188 kwh/ m2.a, while the average annual energy consumption and climate conditions roughly in Japan the same building is about 135 kwh/m2.a, that is to say the energy consumption in Beijing city mall to about 40% higher than that of japan. The energy consumption of air conditioning is the main part of the energy consumption of commercial buildings, accounting for 50 to 60% of the total energy consumption. Preliminary estimates, the current national
