现有的蒸汽压缩制冷试验装置通过手动调节电压方法来控制加热功率,以达到控制蒸发温度的目的,当制冷剂冷凝温度不变时,只能被动等待蒸发温度稳定,实际上只能得到一组数据;使用人工智能温度控制器,自动调节加热功率,实现蒸发温度的自动控制,电子电能表记录显示用于加热消耗的电能,在一定温度范围内自动控制蒸发温度.对改造后设备的性能测试数据表明:蒸发温度在0―-15℃内可根据需要调节,制冷量、压缩机消耗功率、制冷系数随蒸发温度的提高而增大.证明改造是成功的.

The evaporating temperature of the available vapor compression refrigerating apparatus for student experiment is controlled by manually adjusting heating voltage,but it is not easy to operate and the test data is insufficient. The evaporating temperature of the apparatus was automatically controlled by employing temperature controller with artificial intelligence. The electric power was recorded by electronicel watt meter. After retrofit,it is easy to control the evaporating temperature and more test data can be recorded. The performance of the apparatus was tested. The results show that the c...
