The issue of renewable energy reliance has been proposed by many state governments across the globe. Relying on renewable energy sources has various benefits including promotion of low carbon production development, as well as addressing energy security issues while steering up economic growth. This trend has also been integrated into HVAC technologies. Many companies all over the world are involved in research projects that are geared towards creating a more energy-efficient traditional system, and also a new type of system that runs off alternative energies such as solar and geothermal.
There are green technologies that are bringing changes to the HVAC systems. Also, more improved technologies are expected in the near future as tech companies continue working towards changing reliance on fossil fuels. Consequently, many experts are always looking for ways to improve air conditioners. Every year, various air conditioning technologies are being introduced in order to make the ACs perform more effectively. The modern ACs are more efficient than the traditional models. Additionally, they have become a bit affordable and that is why they are a norm nowadays. As a result, many people are using air conditioners in their offices and homes.
The following are some of the new innovations and technologies in 2017.
Thermally-Driven Air Conditioning
A thermally driven chiller that is created by an Australian company, Chromasun, offers a low-cost option to the traditional air conditioning units that are electrically powered. These chillers utilize solar energy, but they can also be supplemented by natural gas when the solar power is running short. The solar panels, which are made by the same company, generate high temperature for driving the double-chiller system effectively. The system is said to offer a more improved cooling compared to a photovoltaic system, hence eliminating costs of electricity.
Ice-Powered Air Conditioner
The Ice Energy uses an ice-powered unit known as the Ice Bear to provide cooling in buildings as well as reducing building’s total energy consumption. The Ice Bear functions through chilling 450 gallons of water in a tank and then make the frozen water available for cooling the following day. The Ice Bear is turned from its Ice Charging into Ice Cooling mode so that it can provide cooling for more than 5 hours. Once the ice melts completely, the cooling reverts back to the conventional commercial building AC unit. This is why the Ice Bear works together with a conventional unit.
Unlike many of the latest technologies, duct wrap has been around for quite some time. The Quiet-Duct Wrap is considered a green technology and the distribution is available in a few countries including the US. It is made of recycled denim fabric, which has been sidetracked from the landfill. While it has low VOCs and no irritants, it also reduces heat loss and gain, which happens via the air ducts. With the absence of fiberglass, it eliminates the possibilities of skin irritation and itching, as well as carrying a Class-A Fire Rating. It has an aluminum barrier that offers protection from moisture, air currents, vapors, as well as reflecting unnecessary radiant heat.
Energy Analysis Software
According to Trane, a world’s provider of heating and air conditioning systems, the energy analysis software can be used to project an energy efficient and cost-saving HVAC system for a particular space before installing and using the system. It can also be used by architects and engineers as an appropriate tool for designing purposes. The equipment can be used to project the energy usage of a building as well as taking into consideration the outcome of non-HVAC methods such as applications of reflective roofing.
Some of the air conditioning technologies have not been approved fully, and therefore they are still concepts. However, once they turn to be a reality, there will be many changes as far as air conditioners functionalities are concerned. Sound-wave cooling and smart-metals are also other technologies in the AC industry. The sound-wave cooling utilizes the helium gas rather than the refrigerant. On the other hand, the smart-metal is still a concept and uses shape memory alloys capable of transforming in response to applied stress, and thus capable of removing heat from a room during the transformation process.
