设计了一种热泵驱动的溴化锂溶液深度除湿机组,该机组适用于无回风可利用、低湿度需求的场合.机组的性能测试结果显示,当室外温度为28～31℃,含湿量为11～14g/kg时,机组的送风温度为1.6～2.6℃,含湿量为2.6～3.0g/kg,系统COP为1.8.测试时发现了一个造成冷热溶液混合损失的管路链接问题,并对其进行修改.然后,对修改后的新机组进行了性能测试,结果显示,在室外温度为25～32℃,含湿量为18～21g/kg时,机组的送风温度为3.2～4.0℃,含湿量为3.4～3.6g/kg,系统COP为2.8.最后,对机组建立数学模型,并将模拟结果与实测数据进行比较,结果表明管路改动使机组性能提升约20%.
A deep-dehumidification unit of heat pump driven lithium bromide solution was designed, which is suitable for the occasions where no return air can be used and low humidity is required.The performance test of the unit shows that when the outdoor temperature is 28 ~ 31 ℃ and the moisture content is 11 ~ 14g / kg, the air temperature of the unit is 1.6 ~ 2.6 ℃, the moisture content is 2.6 ~ 3.0g / kg and the COP of the system is 1.8. During the test, a pipeline connection problem caused by the mixing loss of hot and cold solutions was found, And then modify the new unit.After that, the performance of the new unit is tested and the results show that when the outdoor temperature is 25 ~ 32 ℃ and the moisture content is 18 ~ 21g / kg, the temperature of the unit is 3.2 ~ 4.0 ℃, the moisture content is 3.4 ~ 3.6g / kg, the COP of the system is 2.8. Finally, a mathematical model is established for the unit, and the simulation results are compared with the measured data. The results show that the pipeline performance is improved by about 20%.
