New air conditioning technologies are being developed quickly as older air conditioning systems are outdated. These new innovations in AC design include more energy efficient systems based on simplified mechanical designs. These newer systems also use natural cooling methods such as water evaporation techniques instead of chemical based refrigerants which can harm the environment.
To keep you updated on the new development of AC systems, we have an interview with Jesson from royalrefrigerationllc.com/air-conditioning/. He took you through six new air conditioning technologies to keep you cool:
01) heat pumps
While heat pumps were originally designed to circulate warm air, they are increasingly being used for cooing and heating your home or office. Advances in heat pump technology now enable the replacement of potentially harmful chemical-based refrigerants used in standard air conditioning systems. In addition, a simplified mechanical design with fewer moving parts has made the new heat pump technology much more reliable and energy efficient than the older heat pump technology.
The new “slim” technology uses the same principle as newer smartphones, making the devices thinner, lighter and more efficient. Since the new heat pumps do not use old refrigerants, the system does not need to be charged and the environment is much less endangered. Because newer heat pumps take up significantly less space than older models, these units can be installed in areas that are too small for larger conventional HVAC systems.
2) water evaporation
The water evaporation occurs through natural ventilation. New techniques called membrane-based air conditioning use nozzles to humidify materials like ceramic pads that hold water. Thermodynamics causes the cooler air to move down as the water absorbs heat from the air. This is the same basic principle as with sump coolers, but with much more efficient results.
Another innovation in water evaporation cooling is a multi-purpose technology that uses air conditioning, water heating and dehumidifiers to maintain ideal humidity levels to both cool and prevent mold from forming. The energy released during the dehumidification cycle is used to heat water. Both systems are used in the development of new rooftop air conditioners, and water evaporation systems also work without the need for potentially harmful chemical refrigerants. These AC systems have the potential to reduce energy consumption by up to 50 percent.
3) Extended heat exchanger
While advanced heat exchangers are not widely used right now, these devices can both increase the efficiency of your current AC unit and reduce the overall energy costs. The technology behind an advanced heat exchanger increases the efficiency of your traditional AC unit by reducing the risk of refrigerant leaks. This is achieved by reducing the number of connections in the components of the HVAC cooling system by up to 90 percent compared to conventional heat exchanger units. Since most of the refrigerant is lost in these system connections, the risk of chemicals being released into the atmosphere is also significantly reduced.
4) Energy storage systems
The energy storage system uses the available resources and uses the so-called "inferior" or "waste heat". This is heat generated by other devices that consume energy and then reclaim it. This recovered thermal energy can then be used to power other devices, e.g. B. for HVAC systems and referred to as GLIDES. The integrated diverse energy storage system on the ground was developed by Oak Ridge National Laboratory in Tennessee to reduce CO2 emissions and has the potential to improve HVAC performance by up to 35 percent.
5) hybrid materials
While materials like concrete are very effective at storing heat, they are estimated to cause up to 10 percent of the world's total greenhouse gas emissions during manufacture. However, like standard concrete, new hybrid materials such as wood and concrete can store heat while reducing environmental impact.
Phase change materials or PCMs are even more impressive solutions. These materials can store latent heat and then release it when the phase of the material changes. For example, PCMs give off heat when they freeze and then create a cooling effect when they reheat and absorb heat. Research has shown that PMCs, when used with an AC unit, can lower the building's internal temperature by over 40 degrees Fahrenheit while reducing energy costs by over 25 percent.
6) Sensory air conditioning
AC sensory systems, also known as motion activated AC sensory systems, follow you when you move around a building. Developed at MIT, the system uses motion sensors that detect your movements and turn the air conditioning on and off as needed by tracking both your speed and your location. This type of system has also been referred to as "cloud cooling" because it only cools the currently occupied areas rather than cooling the entire building and wasting energy trying to cool unoccupied areas. While sensory AC power is still in its infancy, this is one of several examples of how new AC technologies are becoming more energy efficient.
