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…

A Breath of Fresh Air—Necessity, Not Luxury

Picture yourself in a building with minimal windows, vents, doors, and other openings. There is no movement at all in the stale and dense air. Feeling uncomfortable yet? While some may say you could endure this environment at home, work or in public spaces, this is not simply a bit…

Debate on air conditioning as a basic right

Is access to cool air a human right in today’s environments? Canada is debating the question, and climate activists aren’t the only ones pressing the issue. A coalition representing private and public sector interests – including insurance companies, the Canadian Chamber of Commerce, the Federation of Canadian Municipalities and the…

Responsible Refrigeration No 79

Training on the new SARACCA training manual introduced at the beginning of 2022 provides an understanding of the Pressure Equipment Regulations, SABS standards and good engineering practice in refrigeration. while the use of the F-gases continues through the phase-out of HCFC and HFC’s refrigerants the appearance of flammable refrigerants has…

Responsible Refrigeration No 78

The requirements of the SAQCC Gas registration revolve around the safe handling of refrigerant gases by practitioners. The training being followed with the new SARACCA training manual provides an understanding of the Pressure Equipment Regulations, SABS standards and good engineering practice in refrigeration. There is also continuing training and education…

Greener air conditioning for a warmer world

When the heat of summer hits, air conditioners turn on and energy demand skyrockets, straining the grid. In a warmer world, more efficient cooling options will play an important role in curbing the increase of cooling-related energy demands. This will be particularly true for the nearly 80 percent of the…

Responsible Refrigeration No 77

Why is it necessary to be registered as an authorised refrigeration practitioner? Now as part of that necessity it is the legal requirement to issue a Certificate of Conformity.
