Description

Photovoltaic direct-drive air energy unit Technical Field The invention relates to the technical field of photovoltaic air energy units, in particular to a photovoltaic direct-driven air energy unit. Background Under the push of global energy transformation targets, efficient and clean composite energy systems have become the focus of research and application. The photovoltaic direct-driven air energy (heat pump) unit is one of main research directions, and is characterized in that the photovoltaic power generation technology and the air source heat pump technology are deeply integrated, so that direct and efficient conversion from solar energy to heat energy is realized, and the comprehensive energy utilization efficiency is greatly improved. For example, the Chinese patent publication No. CN119687591B discloses a photovoltaic direct-driven air source injection-compression combined cycle heat pump cogeneration system, and the system utilizes photovoltaic electric energy to assist to supply energy to a heat pump compressor through intelligent control, and has the advantages of low operation cost and remarkable environmental protection benefit. In the above system, the photovoltaic array is used as an energy input end of the system, and the performance and stability of the photovoltaic array are important. Currently, photovoltaic arrays of such systems are typically constructed of multiple groups of fixed or conventional adjustable-pitch photovoltaic panel assemblies, mounted on roof or open ground, with an incline to maximize solar radiation reception. However, this conventional arrangement has an inherent, weather-constrained significant disadvantage in that its power generation is entirely dependent on solar intensity. Under the weather conditions of insufficient illumination such as overcast and rainy, haze, the electric energy output of the photovoltaic panel drops sharply or even stops, so that the whole photovoltaic direct-driven system has to rely on the power grid to supplement electricity more, and the use cost of the air energy unit is increased. In order to cope with weather changes, some foldable and collapsible photovoltaic panel designs have appeared in the industry, aiming at protecting the panel or reducing wind load in severe weather. However, most of these designs are passively protected, and environmental energy in severe weather (such as rainfall) cannot be actively utilized, so that the energy collection function of the whole assembly is actually in an idle or inefficient state in a period with the lowest photovoltaic power generation efficiency, and waste of resources and equipment utilization rate is caused. In the prior art, an integrated device which can be highly integrated with a photovoltaic panel body, has a compact structure and can intelligently switch working modes in two modes of sunny and rainy days is not yet available, so that solar energy, water energy and wind energy (temperature difference wind) are realized, and multi-energy complementary collaborative power generation is realized. Disclosure of Invention Aiming at the defects in the prior art, the invention provides a photovoltaic direct-driven air energy unit which can adapt to weather changes and comprehensively utilize solar energy, rainwater kinetic energy and temperature difference wind energy to generate electricity.
