Energy recuperation: evaluation of a battery heat exchanger using circulation of a water and glycol mixture

Using systems for collecting hazardous substances at source is very often the only solution that makes it possible to preserve the health of workers exposed to such substances. Unfortunately, the air extracted in this way must be compensated for by energy-guzzling ventilation systems. However, the resulting extra costs may be offset by installing energy recuperators. Various technologies are available today,
including the technology constituted by a heat exchanger having batteries and using circulation of a water and glycol mixture. An evaluation of such a system conducted in an anatomical pathology laboratory thus shows that the resulting savings can reach 2,000 euros per year. This means that such systems can pay for themselves within 4 to 6 years.
