Abstract
The invention belongs to the field of energy conservation, and in particular relates to a highly-efficient gas-water hybrid solar heat collector and application thereof. In the invention, the form of a traditional panel type solar water heater is utilized, a full copper heat collecting plate is formed by splicing tube plate type heat collecting strips, a secondary tube at the back of each heat collecting strip is respectively connected with an upper main tube and a lower main tube, and a high-absorptivity and low-emissivity selective coating is sprayed on the front surface of each heat collecting strip. Simultaneously, a space between the heat collecting plate and a glass cover plate is taken as an air flow channel and is uniformly provided with four glass baffles such that the residence time of the air in the heat collector is prolonged and the air turbulence in a chamber is strengthened. When the highly-efficient gas-water hybrid solar heat collector is applied to a highly-efficient gas-water hybrid solar heat collecting system, hot water flows in copper tubes at the back of the heat collecting plate, the air flows in the chamber between the heat collecting plate and the glass cover plate, and the hot water and the air are not interfered mutually, thus the highly-efficient gas-water hybrid solar heat collector disclosed by the invention can be used for heating water for daily life in summer, heating the air for heating or drying in winter and simultaneously heating the water and the air in spring and autumn, and the annual utilization rate of the heat collector is increased; in addition, the problem that a solar air heating system is overheat in summer is solved at the same time.
Description
Technical field
The invention belongs to energy-saving field, be specifically related to a kind of efficient air water complex type solar heat collection device and application thereof.
Background technology
In solar thermal utilization, solar water heater has formed industry at present, and the output of the annual solar water heater of China has reached up to ten million square metres, has a large amount of solar energy air heat collectors to be used for drying or heating again simultaneously.But in the prior art, no matter be that solar water heater or solar energy air heat collector are independent use mostly, promptly solar water heater can only be supplied with hot water, and solar energy air heat collector can only be supplied with hot-air.
In the winter time, the solar energy air heat collector heating system can satisfy the building and heating demand well, but in summer particularly in period that building need not to heat, this system not only there is no need, and can cause building overheated, and cause the annual utilization rate of system low, influenced the economy of system.For this type of problem, usually the way that adopts be in heat collector to the outdoor air port of offering, the heat of draining, but, still can not solve the building problems of excessive heat because the greenhouse effect of glass cover-plate also can only be alleviated problem to a certain extent.
Solar water heating system is simple in structure, technology maturation and cost are lower, just becomes the solar energy utilization technique worldwide with fastest developing speed and use the most general technology from beginning occurring.But it also has significant limitation: solar water heating system is when cold district is used in the winter time, and water temperature is crossed low even system freezes and cause system effectively to use; The conventional mounting mode is installed on the building roof with system, and the attractive in appearance even city integral image of influence not attractive in appearance building is installed, and the FRAME ON THE ROOF OF HIGH-RISE BUILDING area can't satisfy the demands etc.
Solar air-water both heat collecting device has two kinds of forms at present, a kind of is vacuum tube type, on the basis of original full glass vacuum tube solar water heater, increased air circulation duct, but it can't realize adding simultaneously hot-air and water, wanting to add hot-air just must drain water, want to add hot water and then will be converted to water to circulatory mediator by air, the operation more complicated.Another kind is plate, and its principle is similar with the Trombe wall, heat collector is hung on the Nan Qiang, and open two mouths at the back upper-lower position and communicate with indoor, adopts the passive type method of operation.Its shortcoming is that equipment can only be given the south orientation room heating, but sunlight can directly enter the room through the south orientation window in the winter time, so the south orientation room temperature is than other room height, it is not the room that needs most heating, the passive type method of operation is unreliable in addition, and air mass flow is little, and collecting efficiency is low.
