Thermal solar energy

Functioning

The thermal solar installations at low temperature are systems in which the working fluid doesn´t usually exceed 100ºC. It´s field of development is mainly in the building, with the following applications:

  • Supply of domestic hot water
  • Climatization of indoor and outdoor pools
  • Support for heating
  • Solar air conditioning

The basic element is the solar collector, in which the energy transfer is highlighted from the incident solar radiation to a carrier fluid, which is heated

From a functional point of view, a solar thermal installation consists of the following fundamental systems:

  • Collection system
  • Accumulation system
  • Hydraulic circuit
  • Exchanger
  • Regulation and control systems
  • Auxiliary generator

Classification according to the principle of circulation

  • Systems with circulation by natural convection or thermosyphon
  • Systems with forced circulation

Frequent questions

What is solar thermal energy?

It´s the active and controlled use of heat generated from solar radiation.

What is this for?

Its field of development is mainly in the building, with the following applications:

– Supply of sanitary hot water.

– Climatization of indoor and outdoor pools.

– Support for heating.

Is it respectful with the environment?
