摘要
针对张家口农村地区目前存在的火炕、家用燃煤炉供暖的情况,提出清洁供暖方案。介绍燃气供暖热水炉供暖方案(方案1)、空气源热泵供暖方案(方案2)的系统流程及设备配置。将原采用家用燃煤炉(室内散热装置为散热器)的居住用户作为改造对象,计算采用两种清洁供暖方案条件下的设备造价、年运行费用。将费用年值作为评价目标,比较两种清洁供暖方案的经济性。与方案1相比,虽然方案2的设备造价比较高,但年运行费用低,费用年值也比较低。空气源热泵供暖方案的经济性更优。
The clean heating schemes are put forward in view of the existing healing conditions of the fire Kang and the domestic coal-fired furnace in Zhangjiakou rural area. The system flow and equipment configuration of the gas-fired heating and hot water boiler heating scheme （scheme I ） and air source heat pump heating scheme （scheme 2 ） are introduced. Taking the original domestic coal-fired furnaces （indoor heat dissipation unit as a radiator） as reconstruction objects, the equipment costs and annual operating costs of two clean heating schemes are calculated. Taking the annual cost as the evaluation target, the economies of the two heating schemes are compared. Compared with the scheme 1 , ahhough the equipment cost of the scheme 2 is higher, the annual operating cost is lower and the annual cost is lower. The air source heat pump heating system is more economical.
