冷冻水制冷系统控制培训1。由于冷冻水机组常用的控制元件都放在面板布局上，便于学习。2.压缩机采用三相电机代替。从基本的联锁电路、电机启动、正反转控制电路，逐步过渡到往复式/螺杆式冷冻水机组完整控制电路等高级操作练习。3.使用的压力组件是由直接蒸汽加压触发的，因此系统可以接近真实的一个。相反，用于过去教学的传统组件，必须由螺栓或螺丝刀驱动，可以丢弃。4.输入汽压分为低压、高压、油压3种模拟压力，可单独使用和调节，使学习者对各部件的功能有更清楚的了解。 5. The E.O.C.R is equipped in inner circuit system to ensure the security and avoid the damage of equipment while wiring error. 6. The equipment is equipped with 3 magnetic switches, 3 auxiliary relays, 14 indicators, 2 timing relays, 3 different types switches and digital voltage / current meters. Moreover, one can use them to take a lot of practice of low-voltage power control circuit and to test their own designed circuit.1. Knowledge of electric components 2. Knowledge of protective equipments 3. Y-Δ manual lower-voltage start control circuit of 3-phase induction motor 4. Y-Y / Y-Δ circuit of chilled water unit 5. Circuit of chilled water unit 6. Pressure auto-start, manual-start switch circuit, chain circuit practice 7. Forward / reverse rotation control circuit of three- phase induction motor, automatic forward / reverse rotation cycle control circuit
