POWER SUPPLYING SYSTEM USING MIDNIGHT POWER

摘要

PURPOSE: A power supplying system using midnight power is provided to use relatively inexpensive midnight electricity power at daytime. CONSTITUTION: A power supplying system using midnight power supplies midnight power to a cooling/heating equipment and a current converting unit such as an adapter, a converter, an inverter, a transformer and the like. The current converting unit converts an AC current from an AC power source to a DC converted current at midnight. The DC current is stored at a charging device such as a battery. A DC current controlling unit supplies current to a DC motor, a DC heater and a coil to generate heat in the cooling/heating equipment and optionally adjusts operation and stop at daytime and night. A midnight power breaking unit breaks power supply and signals the DC current controller to supply DC current to the cooling/heating equipment.
