摘要
中高温热泵混合工质ZHR02在油溶性、热物性、材料相容性、环保指标等方面的综合性能优越,为中高温热泵新型工质。文中设计了中高温热泵机组,选取ZHR02作为制冷剂进行了中高温热泵实验研究。研究表明,机组在名义工况下能够稳定生产70℃左右的热水,COP达4.3。
The new mixture refrigerant for moderately high temperature heat pump has comprehensive performance in such aspects as refrigerant oil resolvability,thermodynamic properties,material compatibility,and environmental indexes,being applicable to moderately high temperature heat pump.The article has set up a moderately high temperature heat pump system and experimental study on moderately high temperature heat pump system using ZHR02 as refrigerant.Research shows that system can produce steadily hot water at 70℃ temperature,and experimental COP of 4.3.
