It’s not common knowledge, but only 17% of homes in the world have air conditioning. Fortunately, this statistic is going to change, soon, and vary drastically. By the end of the century, within the next 84 years, the number of homes that have air conditioning will rise to about 70%. This isn’t anticipating any radial factors but based on the growing demand of the global middle-class population.
The main way this will be achieved is through technology and the thought that merely cooling an individual’s personal space is much more affordable than an entire building. Consider things like office chairs that provide cooling, or shoes that keep individuals cool as they walk.
Technological Advances In Air Conditioning
It’s difficult to predict exactly, but the amount of energy that even the most efficient air conditioner models consume is a lot for some countries to digest. The United States Government is known for a lot of things, but the DELTA program isn’t one of their more popular ones. DELTA stands for Delivering Efficient Local Thermal Amenities.
For example, they’ve developed a prototype in RoCo, the robotic personal conditioning device. RoCo has a heater and air conditioner attached to a moving base that follows you around through the signal on your smartphone. RoCo will gently blow the warm or cool air at your to help regulate your temperature. In a commercial building, up to 30 percent of energy costs could be saved, especially if RoCo is charged using solar technology.
DELTA has also come up with a wireless powered climate-controlled office chair. It uses only 14 watts to providing heating for its user and 4 watts for cooling. It has cooling and heating elements that are assisted by small fans, and when not in use the whole system powers down to save energy.
One of the most impressive technologies is the thermoregulation of shoes. DELTA calls this the ReBoot, which has thin insoles with water channels running through them. Working like an air conditioner the water absorbs the heat from your feet and disperses it through a small fan in the boot. This works because the feet are part of the body’s cooling system and give off a lot of heat. By making them more efficient the body will cool off faster.
These technologies aren’t currently available on the market, so while we all wait for our own personal cooling accessories we’ll continue to rely on high-efficiency central and ductless air conditioning systems.
