Economic Analysis and Comparison of Heat Pump Systems Using Wastewater with Traditional Air Condition
The paper presents the economic comparing of heat pump using wastewater with other heating and cooling technology for buildings.The coal burning boiler,oil fired boiler,gas burning boiler and electric boiler were chosen to compare with heat pump using wastewater.A profitability evaluation of the investment in above-mentioned four projects and heat pump was carried out,using dynamic annual computation cost.In the research,the periods of time in which the investment is going to return itself were established.The results indicate that initial investment and dynamic annual computation cost of heat pump are lowest except to coal burning boiler.Therefore in current energy and environment policy,heat pump using wastewater as source is worth of popularizing.
