Building HVAC and PV-powered thermoelectric cooling

Scientists have proposed a way to combine thermoelectric modules (TEMs) with rooftop PV to support HVAC function in buildings. They designed a wall-integrated TEM to heat and cool adjacent rooms. An Australian-Indian research group has looked at how thermoelectric modules (TEMs) and PV could be combined to provide heating, ventilation and air…

Responsible Refrigeration No 73

With the now ever increasing use of flammable refrigerants Practitioners must be very aware of the safety requirements when working on refrigeration units using these gases. This was mentioned in a previous article, I wonder who took the time to read this and absorb and understand the dangers. We’ve been…

HVAC design adaptations sparked by the pandemic

The COVID-19 pandemic has sparked a change in HVAC engineering, particularly in medical buildings. Hospitals for instance, were not originally designed to operate with numerous potentially infectious people walking through the doors. However, early in the pandemic, Aspen Medical constructed a 51-bed surge centre in just 37 days. Every bed…
