摘要： After a chiller unit is started, an opening command of 10 pulses is output to an electronic expansion valve, and after a predetermined period of time (at the time of starting with unload) elapses, an opening command of 100 to 150 pulses is output to open the electronic expansion valve up to a predetermined opening degree. Thereafter, a discharge side refrigerant super-heat TdSH is monitored and a closing command of 1 pulse/sec is output to the electronic expansion valve to drive the same in a closing direction in a short time until TdSH becomes 20 K. After TdSH has reached 20 K, a closing command of 1 pulse/3 sec is output to the electronic expansion valve, until TdSH becomes 25 K, to drive the electronic expansion valve 3 at a smaller speed in the closing direction than that speed in the closing direction until TdSH becomes 20 K. After TdSH reaches 25 K, it is judged that an operation has shifted to a stable operation, and the opening degree of the electronic expansion valve is controlled while a suction side refrigerant super-heat TsSH is monitored.
摘要翻译： 在启动冷水机组之后，向电子膨胀阀输出10个脉冲的打开指令，经过预定时间（在卸载时），将100〜150个脉冲的打开指令输出到 打开电子膨胀阀达预定开度。 此后，监视排出侧制冷剂超热TdSH，并向电子膨胀阀输出1脉冲/秒的关闭指令，以在短时间内向闭合方向驱动，直到TdSH达到20K。在TdSH达到后 20K时，向电子膨胀阀输出1脉冲/ 3秒的关闭指令，直到TdSH变为25K，驱动电子膨胀阀3的闭合方向的速度比关闭方向的速度慢，直到TdSH 变为20K。在TdSH达到25K之后，判断操作已经转移到稳定的操作，并且在监视吸入侧制冷剂超热TsSH的同时控制电子膨胀阀的开度。
