Whole-module solar heat collection engineering system

Abstract

The invention discloses a whole-module solar heat collection engineering system which is an upgrade product of an existing solar heat collection engineering system. According to the whole-module solar heat collection engineering system, an original heat insulation water tank and an original forced circulation hot water pump are replaced, and a heat collection piece which originally only has the heat collection function is upgraded to have both the heat collection function and the water storage function; the whole-module design is adopted for the system, forced external circulation is converted into automatic internal circulation, heat loss is reduced, and power loss is reduced. By the adoption of the whole-module design, the defect that a connecting pipeline is too long is overcome, and the defect that the connecting pipeline is frozen and blocked easily in winter is also overcome. The whole system is designed to be compact instead of being incompact in the prior art, in this way, the occupied area is reduced, the stress of the top of a building is made balanced, hot water utilization rate is increased, and heat collection efficiency is improved.

Description

technical field [0001] The invention belongs to the category of solar heat utilization engineering. Background technique [0002] Nowadays, for schools, hospitals, enterprises and other densely populated enterprises and institutions to provide hot water, solar heat collection projects are generally used, and their common characteristics are composed of three parts: the first part is the solar heat collection area; The header box and the bracket form the solar heat collection module, and then the solar heat collection modules are connected in series or in parallel to form the solar heat collection area. The second part is the heat preservation water tank; generally there are two kinds of cylindrical and square. The third part is the electrical control device. Its working principle is to control the hot water pump through the electric control device to forcefully circulate the water in the solar heat collector area and the thermal insulation water tank, and finally make the ...

AI Technical Summary

Problems solved by technology

[0003] After practical application, this solar heat collection engineering system has the following defects: 1. The electrical control device and the hot water pump are prone to failure, which leads to the paralysis of the entire system

2. The connecting pipeline is too long, it is not suitable for heat preservation in winter, and it is easy to freeze and block the whole system, especially in the northern region.

3. Once a solar collector tube breaks and leaks for some reason, all the water in the entire system will flow out, resulting in waste of water and unnecessary troubles

4. The shape of the thermal insulation water tank is too large, it is not easy to thermal insulation treatment, and the heat loss is relatively large; moreover, the local pressure on the top of the building is too large
