【摘要】：结合低温工业余热特点和夏季空调系统温、湿度调节需求,该文根据梯级用能原理提出基于喷射制冷和除湿溶液再生的复合冷源系统,以实现工业余热的回收利用。采用数值模拟手段分析低温工业余热温度、冷冻水温度和热湿比对该复合冷源系统性能的影响。研究表明,随着低温工业余热温度和冷冻水温度的升高以及热湿比的降低,该复合冷源系统的COP增大。该复合冷源系统的COP在热湿比较大的条件下,主要受喷射制冷子系统性能的影响;在热湿比较小的条件下,主要受除湿溶液再生子系统性能的影响。该复合冷源系统具有较大的节能潜力和较好的环保效益,可用于高效回收低温工业余热。
[Abstract]:Combined with the characteristics of low temperature industrial waste heat and the requirement of temperature and humidity regulation of air conditioning system in summer, this paper presents a compound cold source system based on jet refrigeration and dehumidification solution regeneration according to the principle of cascade energy use. In order to realize the recovery and utilization of industrial waste heat, the effects of low temperature industrial waste heat temperature, freezing water temperature and heat / humidity ratio on the performance of the composite cold source system were analyzed by numerical simulation. With the increase of industrial waste heat temperature and freezing water temperature at low temperature and the decrease of the ratio of heat to humidity, the COP of the composite cold source system increases. The COP of the composite cold source system is mainly affected by the performance of the ejection refrigeration subsystem under the condition of large heat and humidity. Under the condition of less heat and humidity, it is mainly affected by the performance of the regenerating subsystem of dehumidification solution. The composite cold source system has great energy saving potential and good environmental protection benefit, so it can be used to recover industrial waste heat at low temperature efficiently.
