Problems solved by technology

[0003] The purpose of the present invention is to propose a brand-new design aiming at the deficiencies of the above-mentioned existing technologies. In order to solve the problem that the installation of heat collectors takes up a large area, most of the roofs that can be installed with effective heat collection areas cannot meet the heat supply of 40% of the solar energy contribution rate. The problem of heating load needs; at the same time, in order to solve the problem of high manufacturing and installation costs of solar thermal collection systems, short life, and the common problems of easily damaged collectors and overheating in summer and antifreeze in winter

Embodiment 1

[0057] 1. Determining the collector structure Through the process of project development, determine the structure of the optimal geometric size of the heat collector and concentrator of the CPC parabolic concentrating solar collector.

[0058] 2. Determine the heat collector The heat collector of the CPC concentrating solar heat collector is planned to adopt a composite structure of a circular tube heat aid plate. The circular tube is the main heat collector of the far-infrared coating, and the heat aid plate is a triangular wing-shaped secondary heat collector. The calculation and verification are based on the coordinate formula x=γsinα-ιcosα and y=-γcosα-ιsinα. The circular tube heat collector is used as the The double-sided involute in the center corresponds to the tangent of the circular tube to locate the maximum half acceptance angle of the sun of the collector.

[0059] 3. Make sure that the concentrator takes the moving point M(x1, z1) along the involute of the heat co...

Abstract

The invention discloses a CPC (Composite Parabolic Condenser) parabola concentration solar energy heating system comprising a CPC double-parabola concentration type solar energy heating collector, a solar energy heat-storage water tank with built-in domestic hot water tank, an intelligent control system, a heating cyclic switching and cycling device, a solar-energy complementary heat source and a heating terminal. The invention solves the problems that because the installation and occupation area of the collector is large, a roof which can be provided with an effective heat collecting area can not satisfy the heating load of 40% of solar energy contribution rate mostly, the manufacturing and installing cost of the system is higher, and the collector is easy to damage and is bound to be protected from overheat in summer and freeze in winter. In the CPC parabola concentration solar energy heating system, solar energy photo-termal receiving area is smaller than a solar energy radiation receiving area, and the installation and occupation area is smaller. Compared with a vacuum tubular heat collector, the manufacture and installation cost of the CPC parabola concentration solar energy heating system is 10-20 percent lower, and meanwhile, the service life of the CPC parabola concentration type solar energy heating collector can reach above 25 years and is furthest higher than the service life of the traditional system.

Description

technical field [0001] The invention belongs to the new energy industry and the field of solar energy utilization. Background technique [0002] At present, the heat collection equipment for solar heating in my country mainly includes U-shaped tubes, glass double vacuum tubes, glass single vacuum tubes, and flat plate type collectors, which are planar collectors whose area of ​​receiving solar light and heat is equal to the area of ​​receiving solar radiation. With large ground area, most of the roofs that can be installed with effective heat collection area cannot meet the needs of the heating load with a solar energy contribution rate of 40%. At the same time, there are problems of high manufacturing and installation costs of the solar heat collection system, and the heat collector is easily damaged. Common problems with overheating in summer and antifreeze in winter. Contents of the invention [0003] The purpose of the present invention is to propose a brand-new design ...
