What is the fluid of heat transfer?

Heat transfer fluid concerns the proposed mixture of chemicals that collect and transport heat. These fluids are one of the key technologies that allow the production of electrical equipment from the concentrated solar energy system (CSP). Multiple operating criteria must be determined when choosing a suitable fluid for heat transfer. This is the difference from photovoltaic sun schemes, where light energy captured by photoelectric cells produces electricity directly. In the CSP process, light is concentrated by mirrors that focus on sunlight on the receiver, a tube through which the fluid of heat transfer travels. Hot fluids are then fed to the energy production station. The liquid of heat transfer travels to the horizontal of the mirror resorts acquire heat as it moves from one mirror to another. Other configurations use circular flat mirrors that focus light on the receivers filmed above the mirrors. Systems often have a solar tracking function where mirrors can follow the sunEducation movement over the sky.

hot liquid is pumped to the energy production station on the steam turbine. There the fluid warms water and replaces fuel in a traditional fossil electric station. The heather water circuit is identical, except for the change in the heat exchanger structure between the fluid of heat and water. No gas distributor and exhaust mechanisms are required.

The use of heat transfer fluid is remarkable for two reasons. No fuel was consumed in this scheme; The energy came from sunlight. Therefore, there are no by -products of the combustion. CSP HJAKO benefits of solar fuel photovoltaic plants, but can potentially achieve higher efficiency and larger electrical outputs.

Second, the heat was literally a pipe from one place to another. Engineers usually think that heat is a waste product or by -product, but not a energy carrier. Heat is done withOver the walls of the pipeline and the work with the pipeline, it cannot be easily transported and is best used at the generation site. The use of advanced fluids of heat transfer makes heat transport feasible.

Heat transfer fluid must be carefully designed to have high thermal capacity, high thermal stability and a wide range of operating temperatures. It must either remain a liquid or maintain the properties compatible with the system like gas. The typical fluid of heat transfer has an operating specification 12 C to 400 ^{C (54}
