摘要
鸽舍内部的温湿度直接影响种鸽的产蛋率及肉鸽的生产,在维持适宜的鸽舍热湿环境的同时,采用更节能的空调方案具有重要的工程价值,为此提出两种空调运行方案.采用瞬时系统模拟程序(Transient System Sim-ulation Program,TRNSYS)建立这两种方案的仿真模型,并对比分析两种方案在制冷季节中的空调供回水温差和能效.结果表明:方案Ⅱ的平均供回水温差(3.92 ℃)高于方案Ⅰ(1.67℃),热泵工况节能率达11.6％,水系统节能率达30.05％.在工程中,推荐使用方案Ⅱ.
Abstract
The stability of temperature inside the pigeonhouse directly affects the egg production rate of breeding pigeons and the growth quality of meat pigeons.In order to maintain a stable hot and humid en-vironment in the pigeonhouse,two air conditioning schemes were proposed.The difference in supply and return water temperature and energy efficiency of the two schemes were compared,and the scheme with strong energy-saving performance was prioritized.Using the Transient System Simulation Program simula-tion method,two simulation models were built for the two schemes,and the water temperature difference and energy efficiency of the air conditioning supply and return during the refrigeration season were com-pared and analyzed.The average temperature difference between supply and return water in Scheme Ⅱ(3.92 ℃)is higher than Scheme Ⅰ(1.67 ℃),with a heat pump energy-saving rate of 11.6％and a water system energy-saving rate of 30.05％.Scheme Ⅱ has better energy-saving performance than Scheme Ⅰ.Scheme Ⅱ is suggested to be used as the environmental regulation plan for this pigeonhouse.
