Heatpump technology and it´s application researching

Buildings energy consumption is increasing year by year, and the environmental problem is quite serious. So according to the characteristics of hot summer and cold winter in most area of china, buildings heating and air-conditioning, all can be unified in heat pump systems, especially for the office or business buildings, ground source heatpump system can simultaneously solve the heating and refrigerating problems efficiently. In practice, reasonably layout heatpump system, make full use of the huge renewable energy contained in solar and geothermal energy, and avoid recharge and water connected problems and so on, I´m sure that with the popularization of heat pump technology, it can greatly reduce the energy consumption and environmental pollution.
