| Abstract: |
| A power-electronic umlti-function computer-controlled cabinet . The PID controlrule of incomplete differential increment type with integral separation tenn is used in this sys-tem. This system can automatically adapt the variation of load caused by air temperature andmaintain constant liquid level or running at a low liquid level. Hot water stays in the tanksfor a short hrne, thus reducing geothermal loss apparently. This system is simple in operation,perfect in protection function and high in reliability. It has changed the running manner oftraditional submersible pumps of hot water. |
