Abstract

A heat pump drying and heating system powered by solar energy and wind energy in a complementary mode comprises a solar photovoltaic module, a wind power generation system, a storage battery, an air heating collector, a draught fan, a heat pump, a controller, a drying chamber and a house, wherein the output end of the solar photovoltaic module and the wind power generation system is divided into two branches (I and II), the branch II is connected to the storage battery, the storage battery is connected with the heat pump through the controller, two branches of the heat pump are connected with the house and the drying chamber respectively, the branch I is directly connected with the heat pump through the controller, the air heating collector is divided into two branches (III and IV), the branch III is connected with the heat pump, and the branch IV is directly connected with the drying chamber. The heat pump drying and heating system powered by the solar energy and the wind energy in the complementary mode can generate electricity by combining the solar energy and the wind energy, effectively improve the comprehensive utilization rate of the solar energy and the wind energy, lower environmental pollution, achieve the purpose of continuously drying agricultural products, avoid the problem that the quality of the agricultural products is lowered due to manual airing, and provide a heat source for heat supply of the house.

Description

technical field [0001] The invention relates to a heat pump drying and heating system, in particular to a heat pump drying and heating system with complementary energy supplied by solar and wind energy, and belongs to the technical field of new energy. Background technique [0002] As the energy crisis and the greenhouse effect become more and more serious, the national policy is gradually inclined to the direction of energy conservation and emission reduction. Among them, solar photovoltaic and wind energy and their application are an important part of the energy saving and emission reduction, and also an important part of renewable energy, and gradually become the hot spot and mainstream of green energy. [0003] Renewable energy such as solar energy and wind energy has the characteristics of cleanness, pollution-free, wide distribution, and unlimited reserves. However, both wind energy and solar energy have the weakness of low energy density and poor stability, and are af...
