摘要

摘要: 基于我国农村特点提出采用清洁能源利用技术——低温空气源热泵采暖方式替代农村传统的散煤燃烧取暖方式。低温空气源热泵采用较为成熟可靠的补气增焓技术。研究表明:在蒸发温度为-30 ℃、冷凝温度为45 ℃、补气比为0.6的模拟工况下运行,低温空气源热泵理论制热性能系数(COP)大于2.25,系统能效比(EER)高于1.90。在实际应用过程中,低温空气源热泵机组可解决不同场合下需依靠不同介质(热风或热水)采暖的问题,预计全面推广后,我国农村地区每年可减少二氧化碳、二氧化硫、氮氧化物和粉尘排放分别约3.86亿、0.115亿、0.057亿和1.05亿t,其可作为淘汰农村传统采暖方式的优先选择。

Abstract: Based on Chinese rural features, a heating way adopting an air-source heat pump (ASHP) for low cold climate that is a novel and pollution-free technique of energy utilization is proposed. The technique is feasible to replace the traditional heating way of dispersed coal combustion. The air-source heat pump is with a stable and reliable design of adding refrigerant for enthalpy increment. The results showed that under the simulated conditions of the evaporation temperature of -30 ℃, condensing temperature of 45 ℃, and ejecting refrigerant ratio of 0.6, its coefficient of performance (COP) is more than 2.25 and the energy efficiency ratio (EER) is more than 1.90 in theory. During its application in practice, the air-source heat pump could heat by warm air or water to meet with different needs. It is projected that about 386 million tons of carbon dioxide, 11.5 million tons of sulfur dioxide, 5.7 million tons of nitrogen oxide and 105 million tons of powder and dust could be decreased annually if the heat pumps are popularized in Chinese countryside. It can serve as an optimal scheme to phase out the traditional heating way in the countryside.
