How heating technology helps thermal comfort?
Author: Rointe
Discover how heating technology helps you to maximise your thermal comfort. Fuzzy Logic Energy Control will take care of your comfort while optimising energy use.
Thermal comfort is one of the keys to feeling comfortable in our home or room, but do you really know how to achieve it?
When you are designing your heating system, you sometimes forget to give thermal comfort the importance it deserves. You may not know much about thermal comfort, but it’s a crucial aspect of improving your day-to-day living.
For this, there are different methods to measure the thermal comfort of a space.
What is thermal comfort?
It’s a set of conditions including air temperature, movement and humidity that makes your stay in such a space pleasant. Its measurement is subjective as it depends on the subject’s feeling of thermal satisfaction.
Depending on your needs, you can reduce energy costs whilst maintaining the maximum level of thermal comfort.
When designing your heating system, consider your thermal comfort to achieve:
- Reduction in heat loss.
- Balanced energy consumption.
- An increase in energy savings.
- An increase in the well-being and health of the user.
What are the key parameters for optimum thermal comfort?
There are 6 principles of thermal comfort to deliberate when choosing or designing your heating system:
- The type of clothing worn by the user.
- The temperature of the room.
- Any physical activity the space is designed for.
- The airspeed within the room.
- The room’s relative humidity.
- The average radiant temperature of the room.
The Leusden and Freymark standard for comfortable warmth is 18-22 ºC for normal, healthy adults who are appropriately dressed. Those with respiratory problems or allergies recommend no less than 16 ºC, and for the sick, disabled, very old or very young, a minimum of 20 ºC.
With a temperature set around 21ºC in winter, you can maintain the optimum level of thermal comfort, without increasing your energy expenditure.
Did you know that decreasing the temperature by just 1 ºC can reduce your heating bill by up to £85 per year? Most of us won’t even notice such a small difference, so give it a try to ease the financial worry of heating your home.
We also recommend keeping the airspeed of your heating system below 0.1 m/s and the relative humidity of the space between 40-70%.
Falling outside of these parameters can have a negative impact on productivity and health, like sleep quality. Studies have shown that bedrooms with high temperatures lower your quality of sleep. Did you know that 90% of our time is spent indoors, with the majority in working environments and homes? So, maintaining an optimum standard of thermal comfort is essential for everyone. High temperatures combined with high relative humidity reduce thermal comfort and indoor air quality.
That’s why it’s time for your heating system to advance and become more than just a simple heater. It’s now about thermal comfort and well-being as well as warmth.
What Rointe offers you to achieve maximum thermal comfort?
Rointe radiators have been designed for maximum comfort and efficiency.
- Best cost/conductivity material on the market: the aluminium of our radiators, together with their design, allows the steady increase of air temperature when circulating through the radiator’s internal fins.
- Thermal stability: the thermal fluid inside the radiator ensures that the temperature remains stable.
- Efficient and uniform heating due to thermal resistance located at the bottom of the radiator.
- Natural humidity and temperature stability: the air rises gently in temperature as it passes through the radiator, creating a gentle natural convection cycle in your space.
And that’s not all, do you know about our patented Fuzzy Logic Energy Control technology?
All Rointe radiators and towel rails include patented energy-saving technologies, developed exclusively by our electric heating experts, to increase your savings in the most efficient way without reducing comfort. We call it Fuzzy Logic Energy Control technology.
This technology, together with Rointe’s energy-saving functions, achieves an equivalent consumption coefficient of only 38% to maintain a stable temperature of 21ºC for 24 hours. Your Rointe radiator will use, on average, only 38% of its nominal power once a steady working rate has been achieved.
What is Fuzzy Logic Energy Control?
Developed by us, Fuzzy Logic Energy Control is a specialised efficiency technology that improves the energy management required to maintain a stable temperature by accurately analysing thermal variations within ± 0.25ºC. Together with high-purity aluminium and high heat transfer thermal fluid, our low-consumption technology transfers heat to the atmosphere in the most efficient way for your warmth and comfort.
How does Fuzzy Logic Energy Control work?
By analysing temperature variations with an accuracy of ±0.1ºC and sending readings every minute to the microprocessor, we ensure that the exact amount of energy is sent to the heating element at any given time. The heat generated is transferred to the thermal fluid and the aluminium that forms the radiator so that it is dissipated in the most efficient way.
The two main benefits of the use of such technology are:
In addition, it allows you to achieve an equivalent coefficient of consumption of 38% of the nominal power of the product, which translates into energy savings during the operation of the radiator.
Defined by Rointe, the equivalent coefficient consumption ratio is used to calculate the effective power (or average power of use) of our products based on their nominal power.
NOMINAL POWER x EQUIVALENT COEFFICIENT CONSUMPTION RATIO = EFFECTIVE POWER
So for example, take one of our radiators with 990 watts then multiply by the equivalent coefficient consumption at 38%. This gives an effective power of 376 watts for the radiator, once the steady working rate has been achieved (normally after around 45 minutes of heating on full power).
Test results
In an independent laboratory test carried out by BSRIA, one of our 1,430 W radiator with Optimizer Energy Plus technology was tested. This concluded that to maintain a room temperature of 21ºC with a variation of only ± 0.25ºC during a period of 24 hours, our radiator only needed an average of 572 W or 40% of its nominal power.
Improving energy efficiency with Fuzzy Logic Energy Control
We wanted to develop a newer technology that would improve energy efficiency even further, so we created Fuzzy Logic Energy Control. This improves the algorithm of our previous technology, Optimizer Energy Plus.
In a comparative test, carried out in a fair climatic chamber, we tested our latest low-consumption technology (Fuzzy Logic Energy Control) against the previous one. This concluded that Fuzzy Logic Energy Control was able to save a further 6% of energy and reduce the equivalent coefficient of consumption to 38%, our best ever.
