多功能多联式空调(热泵)机组热回收性能分析

摘要

提出一种具有多功能的多联式空调(热泵)系统,并对其制冷+制热水运行模式(热回收模式)进行试验研究,从而给出保证机组良好运行及实现最大热量回收的水流量条件及合理的温度设定条件,水流量不应小于1.0 m3/h,水箱水温设定值不宜大于50℃.%One kind of multi-connected air-conditioning (heat pump) system with multi function is put forward,and the experimental study on the refrigeration and water heater mode (heat recovery mode) is conducted.Meanwhile,the proper water flow and the set point temperature which make the unit operate well and achieve the maximum heat recovery are put forward.Namely,the water flow should be not less than 1.0 m3/h,and the temperature set point should be not greater than 50 ℃.
