Man can live in a wide range of temperatures and in general conditions. Under some circumstances, however, they are more enjoyable. These are the conditions of thermal comfort that directly affect wellness:
- The temperature of the air and the surfaces of the space
- The humidity of the air in the space
- The ventilation, movement and air purity inside the space
These conditions are called wellness conditions and are directly related to thermal comfort.
Thermal comfort is not only about winter conditions, but is related to conditions throughout the year. Thermal comfort is the condition in which an individual does not want any thermal change in the indoor environment and is completely satisfied with the prevailing conditions. To create the right conditions and achieve thermal comfort, the following should be taken into account:
A. The room air temperature & the temperature of the surfaces surrounding the space
By trying to determine the appropriate indoor temperature it would not be right to rush and give a value e.g. 20 ° C or 22 ° C because the appropriate room temperature is affected by various parameters. The reason is that the appropriate temperature is different in the winter and different in the summer or there is still a difference if we refer to a home, a restaurant or a factory where there is intense physical activity.
In addition, the temperature of the surfaces surrounding the space should be taken into consideration. If the temperature of the walls is much lower than the air, we need to heat the air more in order to obtain the required wellness conditions.
A conventional heating system that does not have modern temperature control systems cannot create thermal comfort conditions in a room since in the process of approaching the desired temperature; fluctuations are created which considerably reduce the comfort conditions in the space.
In order to achieve thermal comfort, modern temperature control systems are required, such as PID or PWM thermostats
The PID or PWM function within the most modern thermostats is about the thermostat's ability to perceive at any moment, not only the temperature of the room (like a conventional ON / OFF thermostat) but also, how quickly it changes (rises or goes down) , thus maintaining the room temperature stable.
Operation: PID thermostats are equipped with a microprocessor which:
i. It compares the desired temperature and the current one at regular intervals
ii. It records how quickly the deviation between the desired and the current temperature changes
iii. It foresees future deviations
Result: Through the above analysis, the thermostat selects the operation of the heating system in such a way that it reaches and maintains the desired temperature with the fewest possible fluctuations.
PiD control thermostats can achieve excellent comfort conditions since the temperature is constant but also economical because the space does not heat up more than you need.

B. The humidity of the air in the space
In the atmospheric air there is water vapor from the evaporation of wet surfaces, especially seas, but also from the rainfall. The presence of these vapors in the air is called humidity. The humidity of the atmosphere is "absolute" and "relative".
Absolute Humidity: The mass of water vapor found in a cubic meter of air. This is the density of air in water vapor.
Relative Humidity: The amount of water vapor contained in the air to the maximum amount of water vapor that the air can hold without liquefaction.
Relative humidity is expressed as percent. When we say that the air has a relative humidity of 100%, it means that the air is saturated and begins to humidify the extra vapor.
To get comfortable, the relative humidity should be between 45 ~ 55%. Moisture ratios smaller or larger adversely affect comfort conditions and cause various problems both in the building's materials and in the health of the occupants.
By controlling the humidity level, the quality of the indoor air, e.g. the human body "feels much more comfortable" in a room with 20 ° C and 50% humidity, than in a room with 23 ° C and 67% humidity.
To achieve thermal comfort, it is necessary to use an appropriate air dehumidifier
By using a dehumidifier, high air quality is ensured as they are the best solution for dealing with high relative humidity and improve sensible temperature.
Dehumidifiers with their unique functions:
- Eliminate mold & unpleasant odors.
- They fight the onset of allergies & respiratory infections.
- They save on heating costs up to 30%.
- They protect the masonry, the ceilings, all the equipment in the space and the wooden floors.
- They have a special setting for drying clothes.

C. Air movement, ventilation & air purity
The provision of fresh air in a space is necessary for the renewal of oxygen, the dilution of tobacco, odors, pollutants and carbon dioxide produced by humans. For this reason, the amount of fresh air needed per room is calculated per person in m3 / h, taking into account the number of people in the room and their physical activity and the size of the space to be aerated.
The movement of the air also affects the feeling of thermal comfort. Although outdoors a slight movement of the air can cause us a pleasant feeling, it will not be the same in an interior space. In general, indoors, humans are particularly sensitive to air movement, creating unwanted currents of air and noise.
In order to achieve thermal comfort, it is necessary to use a suitable ventilation-ventilation system with heat recovery
Ventilation with recovery or otherwise heat recovery ventilation systems is the ventilation systems which filter the incoming air and recover the maximum thermal energy of the rejected air.
The heat recovery ventilation system not only “freshens” the air of the room but at the same time recovers the waste heat energy by heating or cooling it, depending on the prevailing thermal conditions within the space.
Mechanical ventilation systems provide fresh, clean air, free from rice and dust, with maximum energy efficiency through heat recovery. The mechanical ventilation unit manages to expel the air from the rooms with increased humidity, such as the kitchen, after having "taken" the heat. When it is necessary, the ventilation system preheats or freezes the incoming air.
The result: an optimal air ratio and a pleasant indoor environment with the necessary Internal Air Quality (IAQ - InternalAirQuality).
Modern Ventilation Systems with Heat Recovery
New technologies dedicated to energy saving and well-being give a different way of interpreting "air" to new controlled ventilation systems (CMV).
