future, they will never lose the supply of air to any part of the hospital. The new plant also uses a controllable global valve on the wet side of the system, to provide optimised control and resilience. The hospital is therefore prepared for the future, taking into consideration any further expansion, or even a future pandemic.
Reliability SHJ’s managing director, Stafford Scopes, said: “The data we are producing is accurate down to every two seconds; we are continuously monitoring how efficiently the RVI’s medical gas plant is running, in real time. No one else in the sector is managing medical gas plant with this degree of accuracy, and we are continuously looking to improve on performance.”
The data Professor Gaoyong Luo, SHJ’s chief scientist, who has developed and led the project from the AI remote monitoring perspective, explained: “Through plotted waveforms, we can demonstrate how the plant is operating at any juncture, and where different usage demands are shown, the system adapts to ensure that the machines are running efficiently. The main compressor (a fixed speed machine) is always running, and is aided by a VSD machine to adjust the speed and adapt to demand variants without wasting energy – the end-goal being to contribute to the Trust’s Net Zero emission targets. Data we have gathered over the past
few months has shown that the frequency of machine cut-in and cut-out has now been reduced significantly, which also helps to ensure that the machines remain in good condition, and reduces the costs associated with non-scheduled service call-outs.” The timeline for the medical gas plant
