Abstract: Ground Source Heat Pump,a kind of heat pump,is a new technology that use shallow geothermal energy for heating and cooling.It is  Usually refers to shift heat or cold from the  underground soil volume to where needed it.Ground Source Heat Pump also takes advantage of the capabilities that the underground soil can store thermal energy and refrigeration.In the winter,ground-source heat pump transferred to the soil from the ground to a building while  it transferred the cold air to it in summer. 

This design is The Wanxiang office building in Changzhou, Ground Source Heat Pump and fresh air hot water Air-conditioning System. The building covers an area of 10000 square meters. The system adopts Ground Source Heat Pump air-conditioning system, office building indoor air conditioning. The cold and heat sources adopt buried tube + cooling tower. The designs include air conditioning load calculation, air conditioning program selection, outdoor buried tube system, and indoor plumbing systems design, cooling tower hydraulic calculation, air tubes and hydraulic calculation of water and related end equipment of air-conditioning selection and calculation. The air conditioning and hot water systems designed to achieve comfortable, environmental protection, energy-saving, economic. According to various calculation results through cost-effective analysis, the selection of equipment to ensure that the equipment capacity, pressure, satisfy noise requirements. The last to draw the related design and construction drawings, complete the final design of the entire air-conditioning system.

Key Words: Ground Source Heat Pump Air conditioning system; buried pipe; cooling and heating load; fresh air system.
