Thermodynamics is a fundamental concept that governs how air moves around in a room and affects heating and cooling efficiency. In this article, we'll explore two principles of thermodynamics: Heat follows cold and hot air rises, and how Biddle's HVAC technology can help overcome these natural forces.

Rule 1 - Heat Follows Cold

The first rule of thermodynamics states that heat always flows from hot to cold until an equilibrium temperature is reached. For example, if it's 5 degrees Celsius outside and 19 degrees Celsius inside, and you open a window, the heat from inside will flow out through the window until the inside of the house matches the same temperature as outside. In the winter, you may keep your windows closed to conserve heat, but customers, staff, and visitors will still need to come and go.

Rule 2 - Hot Air Rises

The second rule of thermodynamics is that hot air rises, leading to a temperature gradient in a room. This convection process causes the upper part of a room to be warmer than the lower part. To achieve efficient heating, it's important to generate heat as low down in the room as possible and consider the entire building's layout. If one room has adequate heating or cooling, while an adjacent room does not, warm air rising from the heated room will pull cooler air from the unconditioned room, making HVAC units work harder.

Biddle's HVAC Technology

Biddle has designed technological advancements within the HVAC industry that enable our heaters to work against the natural forces of thermodynamics. Our Noz2 ceiling-mounted air heater and cooler is equipped with induction technology, providing the following advantages:

  • Fast and even air distribution across the room
  • Minimal heat loss through ceiling and walls 
  • Low temperature gradient 
  • Fewer units needed as a large area is covered 
  • 15% reduction in required capacity

The NOZ2 ceiling-mounted air heater is also equipped with adjustable nozzles that discharge air at high velocity. These air streams take in the surrounding static air, leading to a mixture of air known as induction. This induction process evenly distributes warm air across the room, resulting in a low temperature gradient. The warm air is quickly and evenly distributed, preventing it from lingering near the ceiling and maintaining a pleasant climate on the work floor.

In summary, understanding the principles of thermodynamics is essential for achieving optimal heating and cooling efficiency. Biddle's HVAC technology provides an innovative solution that overcomes the natural forces of thermodynamics, resulting in a comfortable and energy-efficient environment.

Biddle's air curtains (SR, DoorFlow, CITY, Style, and MAT) are all equipped with patented rectifier technology, which provides significant climate separation efficiency, excellent downward penetration, laminar airflow, and benefits to the indoor climate. The patented rectifier transforms the air turbulence caused by the fans into a laminar air stream that reaches the floor at a much lower speed than air curtains without the rectifier. This tight air stream prevents cold air from streaming out, achieving a climate separation efficiency of over 90%.

By using Biddle's air curtains and air heaters, industry professionals can create a comfortable indoor climate while also reducing energy consumption and energy costs. Biddle's air curtains and air heaters are not only an effective solution against thermodynamics, but they are also customisable to meet specific needs and requirements. With Biddle's innovative HVAC technology, industry professionals can create an energy-efficient and comfortable indoor environment for their customers, staff, and visitors.
