农村家用沼气水源热泵空调系统的可行性研究

Feasibility Research on Marsh Gas Air-conditioning System for Rural

通过将天然气压缩动力系统和空调热泵系统结合设计出以沼气提供压缩动能、井水代替冷却水系统的新型空调系统,该系统是在以往的蒸气压缩式中央空调的基础上做了相应的改进,以达到小型农村家用、节能减排的效果。针对该新型空调系统的可行性和经济性展开研究,通过对燃气发动机用于空调行业的发展现状以探究其可行性;在相同工况下,通过理论计算比较该系统与传统空调系统的用电量和制冷性能以证明其经济性。数据分析表明,该系统比传统空调系统更为高效、节能,制冷系数可达5.2,年节约用电量可达15 219.9 k W·h。

The new air conditioning system is designed providing marsh gas as kinetic energy and using the well water as cooling water system the system by combination of gas compression power system with heat pump system.It makes corresponding improvement on the basis of steam compression type central air conditioning, in order to achieve small rural household and the effect of energy conservation and emissions reduction. For the researches on the feasibility and economy of the new air conditioning system, based on gas engine used for air conditioning industry development present situation in order to explore its feasibility, under the same conditions,comparing the theoretical calculation of the new system and conventional air conditioning system power consumption and cooling performance to prove its efficiency. Data analysis shows that the system is more efficient than traditional air conditioning system, energy saving, refrigeration coefficient can reach 5.2, the annual electricity consumption savings can reach 15 219.9 kw·h.
