Problems solved by technology
However, since the radiation cooling film used in this comprehensive application device is directly in contact with the cooling medium, the cooling medium of this device can only be selected as air, and the water system cannot be used, and the heat exchange effect of the water system is better than that of air and it is convenient to store the cold energy. It is used during the day; at the same time, compared with traditional solar collectors, the device does not use glass, which also loses the greenhouse effect of glass, which reduces the heat collection effect of the device

Embodiment Construction
[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0031] see figure 1 , figure 2 and image 3 , water and air dual-purpose flat plate solar heat collection and radiation refrigeration comprehensive utilization device, comprising a box body 1 with an open top surface, the heat collecting plate 4 is parallel to the top surface and bottom surface of the box body 1, and the heat collecting plate 4 is parallel to the box body 1. A number of parallel metal tubes 2 are evenly distributed between the bottoms. All the metal tubes 2 are in contact with the heat collecting plate 4 and the bottom of the box body 1. The two ends of each metal tube 2 are respectively connected to the same tube perpendicular to the metal tube. The header pipe 3 is also connected with the header pipe 3. One end of the two header pipes 3 is closed, and the other end extends to the outside of the box. The outer end...

Abstract
The invention discloses a water-gas dual-purpose flat plate type solar heat collection and radiation refrigeration comprehensive utilization device. The water-gas dual-purpose flat plate type solar heat collection and radiation refrigeration comprehensive utilization device comprises a box body with an opening in a top surface, wherein a heat collecting plate is arranged in the box body; a metal tube is arranged between the heat collecting plate and the bottom of the box body; the two ends of the metal tube are separately connected to collecting tubes and communicate with the collecting tubes;ends of the two collecting tubes are sealed, and the other ends of the two collecting tubes extend to the outer part of the box body; the outer end of one collecting tube is equipped with a cold water inlet, and the outer end of the other collecting tube is equipped with a hot water outlet; a full-wave section high-transmittance material film is arranged in the opening of the top surface of the box body; two glass cover plates are arranged inside the box body between the heat collecting plate and the full-wave section high-transmittance material film; a cavity between the two glass cover plates is a refrigerating medium heat exchange cavity; a cavity between the heat collecting plate and the lower glass cover plate is a heat-carrying air heat exchange cavity; the inlet and the outlet, which correspond to the refrigerating medium heat exchange cavity and the heat-carrying air heat exchange cavity, are positioned in opposite walls of the box body; and a radiation refrigerating film is covered on the upper surface of the upper glass cover plate. The device is good in thermal insulation effect and heat collecting effect.
Description
technical field [0001] The invention belongs to the technical field of renewable energy utilization, in particular to a water and air dual-purpose flat-plate solar heat collection and radiation refrigeration comprehensive utilization device. Background technique [0002] The use of renewable energy is an important way to save energy and reduce emissions. As a clean, common and long-lasting green energy, solar energy has advantages that conventional energy cannot match. At the same time, since the temperature in outer space is close to absolute zero, it is an ideal natural cooling source. [0003] At present, solar heat collection technology is very mature, but due to the influence of day and night changes, solar heat collectors are often idle at night, which greatly reduces their use efficiency; A certain upper limit leads to higher device costs, and it is difficult for radiant cooling devices to achieve cooling effects during the day. Since solar flat panel collectors or ...
