Solar photovoltaic-photothermal-hot wind integrated heat collection device

Abstract

The invention provides a solar photovoltaic-photothermal-hot wind integrated heat collection device. The device comprises a solar photovoltaic system, a solar photothermal system and a solar hot windsystem. The solar photovoltaic-photothermal-hot wind integrated heat collection device has the beneficial effects that a trinity of photovoltaic, photo-thermal and hot wind is adopted; automatic switching of multiple modes can be achieved; meanwhile, different modes of automatic spreading of a V-pattern solar photovoltaic panel can be cooperated; and thus solar energy utilization efficiency can beraised by 5%-15%. By means of the device, combined operation of the three systems can be achieved; the device can be applied to different occasions; and modes can be chosen automatically and switchedaccording to judging conditions by the device, and electricity energy, hot wind and hot water can be provided simultaneously for electrical appliances.

Description

technical field [0001] The invention relates to the fields of high-efficiency development and utilization of solar energy and building energy conservation. Specifically, it relates to a solar photovoltaic-photothermal-hot air integrated heat collection device. Background technique [0002] Solar energy is a kind of clean energy, which has the advantages of no need for mining and transportation, no pollution to the environment, and direct utilization. It is now being developed and used in large quantities, and it can also achieve energy-saving control while efficiently utilizing solar energy. It is a relatively usable natural energy. energy. However, many problems have been encountered during its development and use. For example, the widely used solar heat collection method uses water as the heat transfer medium, which has problems such as leakage, corrosion, and antifreeze, and the collected heat is easily dissipated. The efficiency of absorbing solar energy by the heat co...
