How does it work: Smart thermoregulation

Wingo achieves the best warming efficiency on market and best customer experience as a result of combined research in thermodynamics, anatomy, physiology and comfort research.

Thermodynamics

In thermodynamics we have three main heat transfer mechanism: conduction, convection and radiation.

Second and third are almost exclusively used in the eating establishment, but in Wingo we use the first one: conduction. Why? Because:

  • conduction is the most efficient way of transferring of the heat
  • it provides direct contact between two bodies (in this case between table base and feet)
  • it has minimum dissipation of heat on surroundings (i.e. loss of energy/money)

That’s fine. But how can this help when we know that human body has a large surface and surface of heater source is limited?

Anatomy 

The combination of thermodynamics and human anatomy helps to answer that question. To achieve the best efficiency of heat conduction we need to point to the biggest surface-over-volume area: surface because this is directly proportional to the amount of energy that can be transferred to the given body, and volume because the volume is proportional to the amount of heat needed for given body to warm up for certain degree/s:

dQ=ρ*V*c*dT

The two relevant part of body with maximum surface-over-volume ratio are: feet and hands. During the sitting on the chair in the open air our hands are in constant move, and usually additionally heated by heat from warm drinks/cups. On the other hand, our feet are in direct contact with ground and they are losing enormous amount of heat.

So, feet are the part of the body with best thermodynamics parameters for transfer of heat, and part of the body that mostly need the heat input because of the constant loosing of the heat to surrounding.

Physiology

We have most efficient heat transfer (conduction) and body part with the best thermodynamics parameters for that transfer (feet). But what with the rest of the body? We don’t want to warm up only our feet.

If we were made of stone or steel, the heat from our feet would not distribute within the rest of our body efficiently. But luckily for us, we are living beings with blood circulation and countercurrent exchange of the heat through ours veins and arteries.

Heat from the heat source – table base – is transferred by conduction on our feet, where warms up blood in veins. Blood is then circulating around our body and distribute energy (heat), which makes us generally warm.

And we feel warm.

Comfort research

But we could also transfer the heat to the human body by convection or radiation on larger areas of human body (for example back or chest or pelvis), as the classic heating devices are doing. We could input same amount of energy (warmth) into the body via different parts of body. So why would we choose the feet instead of something more intuitive, as chest and back?

We chose the feet because scientific researches in human thermoregulation and comfort showed that general comfort feeling follows feel of the comfort in feet (and hands). Overall comfort sensation follows that of the feet (and hands).

If you feel cold in your feet (or/and hands) you will generally feel cold, even if you do not feel cold in your back, chest, pelvis or head/neck. 

And that is the final reason of choosing to warm up your feet – feeling of comfort.
