介绍了一种应用于制冷空调领域的新型溶液除湿冷水机组,该系统可以由60～80℃的低品位热能驱动,如太阳能平板集热、余热废热等.对该系统建立了数学模型,理论分析了蒸发温度、再生温度、环境空气温湿度、封闭制冷循环和再生循环空气流量等参数对系统性能的影响.结果表明:系统在参考工况下制冷量为2.5kW,性能系数达0.37,制冷性能良好;再生温度和环境空气含湿量对系统制冷量和性能系数的影响较大,而环境空气温度的影响较小;同时,为了使得系统能够经济运行,再生空气流量不宜过大,而封闭制冷循环空气的流量也需要合理选择.
A new type of solution dehumidification chiller used in refrigeration and air conditioning is introduced, which can be driven by low grade heat of 60-80 ℃, such as solar panel heat collection, waste heat waste heat etc. The mathematical model of the system is established, and the theoretical analysis The influence of parameters such as evaporation temperature, regeneration temperature, ambient air temperature and humidity, closed refrigeration cycle and recirculation air flow on the system performance was studied.The results show that the system has a cooling capacity of 2.5kW, a coefficient of performance of 0.37 under reference conditions, Good; the regeneration temperature and ambient air moisture content on the system cooling capacity and coefficient of performance of a larger impact, and the impact of ambient air temperature is small; the same time, in order to make the system can be economical operation, the regeneration air flow should not be too large, and closed refrigeration Circulating air flow also need a reasonable choice.
