HVAC&R Nation have published an article focusing on eight innovations that are set to transform the HVAC&R world.
These eight innovations are: predictive maintenance, magnetic refrigeration, thermoacoustic refrigeration, fault detection and diagnosis (FDD), prefabricated construction, 3D printing, demand response and augmented reality (AR).
In regards to predictive maintenance, the article states that according to Airmaster predictive maintenance “improves the effectiveness of maintenance by evaluating the condition of the HVAC plant through periodic and continuous condition monitoring. This ‘smart’ monitoring dictates and directs maintenance activities to ensure a building’s HVAC&R systems achieve peak performance on a continual basis.”
In regards to magnetic refrigeration, the article states that in a magnetic refrigeration system “a controlled magnetic field applies a series of magnetisation-demagnetisation cycles to the magnetocaloric alloys. Each cycle creates a temperature gradient in the material, with a rapid succession of cycles producing the final, stabilised hot and cold temperatures in the refrigeration system.”
In regards to thermoacoustic refrigeration, the article states that it works by “using soundwaves and a blend of gases such as helium and argon in a ‘resonator’ to produce a cooling effect.
In regards to fault detection and diagnosis (FDD), the article states that the CSIRO believes the emergence of automated FDD tools could be a “game changer as some tools are already available and the technology is poised to facilitate energy savings and emissions reductions from commercial HVAC systems.”
In regards to prefabricated construction, the article states that “thanks to digitisation and the ongoing desire to reduce costs, lessen construction time and improve on-site safety, prefabricated offsite construction techniques are becoming more popular.”
In regards to 3D printing, the article emphasises that due to the increase of availability and ease of purchase of 3D printers, the “days of waiting for a spare part to arrive from a far-off warehouse are theoretically over. Simply print it overnight, and install the next day.”
In regards to demand response, the article states that it involves “paying an incentive to energy users to reduce their power consumption, switch to back-up generation, or dispatch their energy storage for short periods when electricity reserves reach critically low levels.”
In regards to augmented reality (AR), the article states that the term AR refers to “a direct or indirect live view of a physical, real-world environment whose elements are augmented by computer-generated perceptual information that is both visual and auditory.” In the HVAC&R industry, an example of AR currently in use is in the Netherlands where Daikin have trialled high tech “smart glasses” to help their service engineers in the field. The “smart glasses” provide support by providing access to technical information such as databases and error codes.
