Areas of use of the heat of the sun and the salt pond geothermal source

Of course, with heavy use of geothermal field in winter, not the design stage of buildings and structures should not forget about converting their winter solar radiation into heat (photothermal conversion). It can be either passive (using passive solar building elements - glazed facades, conservatories) and active (with the use of additional technical equipment). The advantage of passive systems is that their operation does not require any additional equipment. Use the sunlight that falls inside the building (structure) through the windows or transparent surfaces. This system should be designed to account for the use of received energy to other premises. Here are the most appropriate capital at home, allowing for a short time to accumulate excess energy. The principle here is also the view and control of the heating system.

The passive system should be unified with the building of a harmonious whole, it easiest to achieve in the new buildings. Old buildings can be reconstructed (to make glazed extensions, porches, etc.). However, it is necessary to take into account the risk of overheating of the building in the summer, which you need to install the appropriate ventilation systems, heat storage building structures.

Passive energy gain of the system depends on the method of use of the building - for example, additional glazing of loggias cost-effective only when it is not heated in the winter.

Common to both heat sources is that as the thermal capacity of the solar pond brine and geothermal source [10] can be used in the same areas of different (Table 5).

As can be seen from the above, solar radiation and geothermal heat can be a source of energy for the combined energy supply systems in Russia, providing round the important areas of life and the production of energy-building.
