What needs attention to solar collector Sunpower heating design?
Publish Time: 2019-07-22 Origin: Site
The solar collector heating system consists of collectors, heat storage equipment, piping systems, auxiliary heat sources, control systems, etc. The system is relatively complex. Therefore, a reasonable design is required before installation. Otherwise, system control failure and energy saving and other issueswill occur.
When it comes to solar collector heating design, it has to be said that solar collector heating design needs to pay attention to the following links.
Design of heat collecting area
The size of the solar collector should be selected according to the temperature required for the actual building heating. The heating energy saving is not prominent, the system cost is increased, and the capital utilization is unreasonable.
System piping design
The design of the pipeline for the entire solar heating system is very important. If the pipeline design is unreasonable, it may lead to insufficient water supply and system shutdown. It is recommended to keep the water balance as much as possible in the pipeline design. The pipeline diameter should match the system design to calculate Reasonable flow of piping.
Auxiliary energy considerations
Auxiliary energy is used to compensate for the lack of solar energy. The choice of it should be economical, energy-saving, convenient and safe. It is recommended to use gas boiler, air energy heat pump, ground source heat pump and electricity. Wall-hung boiler.
Control system considerations
The control system is the central nerve of the solar collector system, and its design should follow the principles of intelligence, flexibility and safety. For example: automatic water supply, water full stop, display water temperature and water level, automatic or timed electric heating, timed water, pipeline circulation and supercharger control; use high quality control system equipment to reduce failure rate and maintain solar collector heating system for a long time Smooth operation.
Selection of hydration system
The hydration system is an important part of maintaining the continuous hot water supply of solar collectors, and there are many hydration equipments on the market. The most common one is the float-type hydration system.
