热泵供热方式供热成本及工程造价对比

Comparison of Heating Cost and Project Cost of Heat Pump

计算锅炉(燃气锅炉、蓄热式电锅炉、生物质锅炉)、热泵(空气源热泵、污水源热泵、地埋管地源热泵)的供热成本(仅为热源设备的电费、燃料费,不包括水泵等其他辅助设备产生的费用),对青岛地区已建热泵供热系统的工程造价进行对比。在当前能源价格条件下,与3种锅炉供热方式相比,3种热泵的供热成本均比较低。在3种锅炉供热方式中,生物质锅炉的供热成本最低。相同类型热泵供热方式的单位供热面积造价接近,空气源热泵的单位供热面积造价最低,污水源热泵与地埋管地源热泵的单位供热面积造价接近且比空气源热泵高。

The heating costs( only electricity and fuel costs for heat source equipment,not including costs of other auxiliary equipment such as water pumps) of boilers( gas boilers,regenerative electric boilers and biomass boilers) and heat pumps( air source heat pumps,sewage source heat pumps and buried pipe ground source heat pumps) are calculated.The project costs that have been built in Qingdao area are compared. Under the current energy price condition,compared with the three boiler heating methods,the heating costs of the three heat pumps are relatively low. Among the three boiler heating methods,the heating cost of the biomass boiler is the lowest. The unit heating area cost of the same type of heat pump heating method is similar,the unit heating area cost of air source heat pump is the lowest,and the unit heating area costs of sewage source heat pump and buried pipe ground source heat pump are close and higher than that of air source heat pump.
