It’s crazy to think that there are people alive today that did not have air conditioning at all or television. Someday people will say the same thing about the internet. In the last 100 to 150 years, civilization has made more progress than human history prior to that in its entirety. It’s no different with air conditioning technology so we will explore some of the immediate and near future of HVAC technology.
Radiant Chilled Beams
This system cools buildings through natural convection and transfer of heat. It uses ceiling pipes that carry chilled water that directly cools the space. One of the main concerns with this system is the possibility of mold and condensation. So far this has been controlled with the use of a dehumidifier. Benefits include 15 to 20 percent lower energy use than for conventional units.
This system uses natural air flow to push hot air upwards and remove it at the ceiling. This unit improves ventilation efficiency and air quality in comparison to normal ventilation. It also saves energy in that it controls the climate only in rooms that are being used.
Sound Wave Cooling
While the previous technologies we mentioned are starting to be used on the cutting edge, sound wave cooling and the technologies that follow are in the development phase. In fact some may or may not ever be used, but trial and error is how engineers figure out what works. Rather than a refrigerant, this system uses helium gas. The cooling action involves using a loudspeaker to turn electricity into sound waves, pressurizing the gas and enabling it to absorb heat while releasing it to the outside.
This concept involves the use of shape memory alloys that can transform in response to stress. They change shape and develop the capacity to remove heat from a room. This is still very much in the concept phase and sounds like something straight out of a Transformers movie.
Photonic Radiative Cooling
This technology is in the prototype stage and being tested at Stanford University. It uses a multi-layered, micro-thin material that reflects sunlight and sends it into space as infrared radiation at a frequency that avoids warming the air. Yes, we mean space as in off of the planet. This system requires no power and is akin to a very powerful mirror that can stop 97 percent of sunlight from being absorbed by a building.
While we may not be able to install an air conditioner that changes into a robot (yet), we stay on the cutting edge so if you have questions about the latest developments to make your home more efficient call 7th Generation Air Conditioning and Heating today at 941-966-1684.
