Abstract

The invention discloses a photovoltaic generation and photothermal heating ventilating high efficiency utilization device based on spectra separation, which relates to a device which achieves high efficiency photovoltaic generation and photothermal heating ventilating utilization based on solar spectra separation, and the device comprises a spectra separation component, a photovoltaic generation component and a photothermal heating ventilating component, wherein incident solar energy is decomposed to a photoelectric effective spectra part and a photoelectric ineffective spectra part by the spectra separation component. The photoelectric effective spectra part does photovoltaic generation through a photovoltaic battery component, and produces parts of dissipation heat energy simultaneously. The photoelectric ineffective spectra part is transformed to heat energy through a photothermal converter, and the heat energy and the dissipation heat energy which is produced by the photovoltaic generation can be jointly used as a driving heat source of the photothermal heating ventilating component. The heating ventilating component comprises a hot water generation component, a solution component, an air treatment component and a refrigeration component, and can achieve to supply cool or heat, desiccant or humidify for air. Biomass heat energy is used as an auxiliary heat source of the photothermal heating ventilating component. The device is particularly suitable for the heating ventilating modes which need to be supplied with fresh air or treat air.

Description

technical field

[0001] The invention relates to a device and method for realizing high-efficiency photovoltaic power generation and photothermal HVAC utilization based on solar spectrum sorting, and belongs to the fields of solar photovoltaic power generation and photothermal HVAC utilization. Background technique

[0002] In today's world, on the one hand, there is energy shortage and power supply shortage. On the other hand, there is a problem that HVAC power consumption is very large and continues to expand. According to statistics, the total power consumption of air conditioners in southern cities in my country accounts for 10% of the total power consumption of cities. 30%-40% of the electricity consumption, while the proportion of air-conditioning power consumption in developed countries has reached more than 40%, so the use of renewable energy to generate electricity and drive HVAC equipment has become a research hotspot all over the world.

[0003] In my country's ener...
