PHOTOVOLTAIC SYSTEM FOR AIR CONDITIONING AND HEATING

摘要

The present invention relates to a photovoltaic power generation system for air conditioning and heating, which allows loads, such as a chiller and a heater, to be operated by power generated by photovoltaic power generation and to be operated while being supplied with a shortage of power from other power supply sources, thereby solving a power shortage and reducing a degradation in power factor. The photovoltaic power generation system according to the present invention comprises: a main power source including a solar cell which generates power, a chargeable battery which stores the generated power, and an inverter which converts the generated power or the power stored in the chargeable battery; a sub power source which is configured by a system separated from the main power source to supply power; a load which is operated by power supplied from one of the main power source or the sub power source; and a seamless switchover unit which performs switchover between the main power source and the sub power source to supply the main power from the main power source or the sub power from the sub power source to the load.
