Adaptive constant-temperature moisturizing photovoltaic agriculture greenhouse support integrated system with waste heat recovery function

Abstract

The invention relates to an adaptive constant-temperature moisturizing photovoltaic agriculture greenhouse support integrated system with a waste heat recovery function. The system is composed of greenhouse supports, solar photovoltaic cell panels, heat preservation films, sensor units, a control unit, a solar driven air waste heat recovery unit, a waste heat recovery air inlet and outlet dynamic regulation unit and a solar-assisted heating unit. A downstream greenhouse and an upstream greenhouse are serially connected through the waste heat recovery unit, inlet air components of waste heat recovery air inlets and outlets are regulated dynamically through data sampling of temperature sensors and humidity sensors, and adaptive ventilation and heat preservation effect in the greenhouses is realized. Excess photovoltaic power generation is used for grid-connected power generation. The system can be applied to heat preservation of agricultural greenhouses, the supply requirements on economy, environmental protection and energy conservation of the system can be met, and efficient heat preservation effect of the greenhouses is realized.

Description

technical field [0001] The invention relates to a photovoltaic power generation system, in particular to an adaptive constant temperature and moisturizing photovoltaic agricultural scaffold integrated system with waste heat recovery function. Background technique [0002] The simple agricultural greenhouse is built into a greenhouse skeleton through a steel structure, and the frame is directly connected to the ground. The thermal insulation film is applied outside the frame and supported by the scaffold structure, and the film is fixed by buckles. The agricultural greenhouse combined with solar energy is to add solar photovoltaic modules on the basis of conventional agricultural greenhouses, and the thermal insulation film is between the solar modules and the framework of the greenhouse. This structure causes the inner frame of the greenhouse to be directly connected to the ground, or exposed to the air through the upper connected frame, forming multiple "cold bridges" to ta...

AI Technical Summary

Problems solved by technology

Because the insulation film is a consumable product with a short service life, the above structure also brings a lot of inconvenience to the replacement of the insulation film

Furthermore, since the greenhouse needs to be constantly ventilated to provide fresh air for the crops, but in the winter when there is a need to keep warm, the entry of cold air will greatly increase the pressure on the insulation requirements in the greenhouse
