Growth of labour productivity and health are provided by the quality indoor climate in buildings

Climate change is also caused by heat waves. In the case of their occurrence the risk of collapse of the body increases by 33% with possible fatal outcome. In 2003 25,000 EU citizens died due to the heat waves; in 2010 the amount increased up to 55,000. Climatologists predict that the increase in temperature will cause a raising frequency of heat waves with all the negative consequences for a human body, bringing along an increase in morbidity, productivity loss, shortening of life expectancy and in extreme cases even collapse of the body.

Mechanisms of human energy expenditure

Upon designing the indoor climate of buildings it is necessary to take into account the physiological characteristics of humans and customize the technical solutions of cooling and heating. The energy exchange mechanisms in the human body consist of heating radiation, conduction, convection, and evaporation whilst the largest component is the heating radiation. On the present it is crucially used in heating elements with vertical temperature profile. Energy in a radiator is transferred through the conduct element and convection, and this leads at first to the heating of air and then the walls. The movement of air results from the energy transfer principles and often exceeds the threshold limit of thermal comfort 0.1 m / s. By using radiators it is impossible to cool the space effectively. Cooling provided by forced air circulation through air conditioning units decreases relative humidity below the recommended level and eliminates the skin microclimate causing false information to provide to thermo-receptors stored in the human skin.

Vertical temperature distribution, using radiators and using radiant ceiling system

The consequence is that with this type of cooling the body is under the thermal stress although the space feels cold. It results in migraine, fever and chronic inflammation multiplied even by swirling of bacteria and mites. Temperature zones of the human body are organized in the way that the body maintains its core temperature at a constant

level of 37 °C, and towards the feet the temperature is gradually reduced. And therefore the solution consisting of micro capillary radiant ceiling system is suitable for such distribution of temperature in the human body.

Human body temperature zones

The system ensures that in both cases heating or cooling the critical part of energy transport is performed by the radiant component. The mechanism operates so that the energy is by radiation transported into vertical and horizontal structures and from these the air is flowing back re-heated or re-cooled.

Radiant ceiling heating and cooling system

With this system there is neither air turbulence nor reduction of relative humidity of the air. The micro capillary mat system is installed on the standardized support structure finished by aluminium ceiling panels, reaching a highly aesthetic type of space.

The thermal imaging photo taken of the heated room shows, that the temperature near the ceiling is approximately 28 °C. The constant temperature in the space between the bottom of the floor and at a height of 2.2 m is 22 ° C. The sensation of temperature that the human body feels is the average temperature of structures and air. With heating by radiators

the structures are usually a few degrees cooler than the air. Similarly, with forced air cooling the structures are warmer than the air. With radiant energy transfer system the temperature of structures is identical to the temperature of the air and thus almost an ideal thermal comfort of indoor climate can be reached.
