利用热泵设备(THY)给工艺过程和空气调节提供综合冷、热源的方案,是合理利用热能资源的新的有前途的和经济上有效的方向。运行经验表明,利用热泵设备可以节省消耗在供热上的有机燃料30～70％;可以消除对周围环境污染的可能性;可以促使工业企业能源的再次利用,从而促进在非传统的能量平衡中利用低位热能,用热泵系统同时给公共设施和工艺过程提供冷、热源;可以降低单位产品的成本和提高产品质量。通过对各种蒸汽制冷压缩机及其工作过程的研究工作和初步的运行经验,已经能够确定在热泵工况下工作的制冷压缩机(使用不同制冷剂,蒸发温
The use of heat pump equipment (THY) to provide integrated cooling and heat source solutions for process and air conditioning is a new promising and economically effective direction for the rational use of thermal energy resources. Operational experience shows that the use of heat pump equipment can save 30-70% of the organic fuel consumed in heating; it can eliminate the possibility of pollution to the surrounding environment; and can promote the reuse of energy in industrial enterprises, thereby promoting the non-traditional energy balance. Utilize the low heat energy and use the heat pump system to provide cold and heat sources for public facilities and processes at the same time; it can reduce the cost per unit product and improve product quality. Through the research work and preliminary operating experience of various steam refrigeration compressors and their working processes, it has been possible to determine the refrigeration compressors operating under heat pump conditions (using different refrigerants, evaporation temperature
