Passive Cooling

What is it? A number of new buildings require low levels of heating in winter, as they are well-insulated and thus excellently equipped to preserve heat energy. This is a huge advantage during periods of cold weather; but nevertheless, their temperatures may seem too high in other seasons, particularly in the summer. Moreover, large window surfaces increase accumulations of solar energy, and heat is additionally generated inside the premises by people, computers, TVs, lighting and other equipment. Such heat needs to be dissipated. Passive cooling is an innovative, modern and environmentally-friendly component of the geothermal system. This technology, in contrast to the geothermal heating, is intended for cooling instead of heating. In simplistic terms, when a geothermal system is installed you will receive a passive cooling system as a “bonus”.

Passive Cooling Passive cooling is an optional mode that is connected to the geothermal system. This additional system conducts, via a collector, the internal heat gained from the building back into the earth. In this way the fluid in the heating system is cooled, creating pleasant coolness that flows through the floor heating system. Such a way of cooling the building is particularly efficient due to its use of the already-installed floor heating system; therefore, a relatively low reduction of temperature gives a significant cooling effect inside the premises due to the large floor area.

Principles of Passive Cooling What is it? It is a very simple process which includes the circulation of non-freezable fluid between the premises and the ground. Excess heat from the premises (A) is carried to the ground by the geothermal collectors (pipes), thus delivering the heat into the cooler ground (B). The fluid, which is now cooled, moves back into the floor heating system to cool the premises. The cooling cycle does not involve any operation of the heat pump.    Advantages of passive cooling: •  No undesirable noises (as in case of traditional

air-conditioners with ventilators); •  Low operating expenses (e.g. cooling an 50 sq. m

apartment may cost 1-2.89 EUR per month); •  The installation of passive cooling is possible

with all types of heat pumps.
