Air Conditioning Heat Pump System Design of Xi'an Third Sewage Treatment Plant

Our country is energetically advocate saving energy and reducing consumption, Application of sewage-source heat pump system than the electric heating boiler save more than two-thirds of electricity, Which save more than 1/2 of coal resources than the traditional coal-fired boiler. As a result of the sewage-source heat pump heat source temperature is relatively stable throughout the year, the refrigeration and heating coefficient is about 40% higher than the traditional air source heat pump. The operating cost is only 50% similar to 60% of ordinary central air conditioning[ 1-2]. The purpose of this article is the third sewage heat pump air conditioning system design for xi 'an to meet the requirements of cooling and heating. Design is from the most basic load calculation, selection of heat pump, water pump selection, the design of heat exchanger, the determination of air distribution, air treatment mode selection, selection of fan coil units at the end of the room design, water system design, drawing design. All the calculation of the selection according to the size of the heating and cooling construction drawings accurate calculation, and is optimized according to different situations.
