摘要
在2种不同室外温度工况下,实验研究了系统在开启蓄能除霜模式时的运行特性,分析了蓄热器的放热特性和高、低温级运行特性。结果表明:2种工况下,机组除霜时低温级的吸气压力均在0.236MPa以上,系统除霜性能稳定,高温级的平均制热量能达到正常制热时的55.4%以上,说明蓄热器能够提供稳定的热源。
Experimentally studies the characteristics of energy storage defrosting mode under two outdoor temperature conditions. Analyses the discharge performance of the thermal accumulator and the characteristics of the high and low temperature cycles. The results show that under the two conditions, the suction pressure of the low temperature cycle is higher than 0. 236 MPa. The system defrosting performance is stable. The average heating capacity of the high temperature cycle is more than 55.4% of the normal heating capacity. The thermal accumulator can provide a stable heat source.
