摘要:
为改善低温环境下空气源热泵机组适应性差、制热量及制热性能低等问题,设计研制了单-双级混合复叠空气源热泵机组试验样机。利用焓差实验室测试分析了样机在不同运行工况及运行模式下的制热性能及其内部参数的变化规律。结果表明:出水温度45 ℃、室外温度-20 ℃时,系统制热性能系数高于2.1、制热量为7.61 kW、压缩比不超过4.5、排气温度低于80 ℃;以制热性能系数为优化目标,确定室外温度0 ℃为该系统单双级切换运行的控制条件。
Abstract:
In order to improve the adaptability,heating capacity and heating performances of air source heat pump(ASHP)units in low air temperature,a hybrid singledouble stage cascade ASHP prototype is designed.The intrinsic operating parameters and heating performances of the prototype in different operating conditions and modes are tested in an enthalpy potential method laboratory.The results show that when the hot water supplying is 45 ℃ and the ambient temperature is -20 ℃,the coefficient of performance in heating(COPh)of the unit is above 2.1,the heating capacity is 7.61kW,the compression ratio is less than 4.5,and the discharge temperature is below 80 ℃.With the optimization objective of the COPh,the ambient temperature with 0 ℃ is taken as the switch temperature for the modes of singledouble stage cascade heating operation.
