This article is the second installment in a four-part series that examines poor indoor air quality (IAQ) in schools and what the HVACR trade can do to help stem the crisis. Here, The News examines ventilation products designed to solve institutional IAQ problems.
MONTGOMERY, Ala. - Charles N. Prudames, 64, died April 4 due to cancer. He had been vice president of Jay R. Smith Manufacturing Co., Montgomery, where he began working in
The dissection room at a university laboratory had a problem controlling the amount of formaldehyde vapor that was emitted into the lab space. The use of an air purification system helped solve the problem.
During recent testing, refrigerated reach-in cabinets were subjected to stress. Part of the equation was the inclusion of technology designed to improve evaporator heat transfer.
Ventilation is included in most indoor air quality (IAQ) solutions. In the case of terrorist activities aimed at underground facilities (i.e., parking garages and subways), it will not work as part of the solution. In fact, it could make the situation worse if chemical and biological contaminants are released to the general public outside. This was the consensus of the speakers at a recent ASHRAE seminar.
Call it the final word. At the end of the daylong HVACR competition at SkillsUSA, time was set aside for a debriefing. Here is a sampling of what the industry experts had to say.
What do you say to young technicians just starting out in the business, who have already proved that they excel in technical knowledge? You tell them that a lot more is needed to stay in the business and keep their customers happy.
Problems with glass door reach-in freezers include the icing up of evaporator coils. Various heaters in the equipment as well as the defrost system may need servicing. Cleaning is an important task in keeping the case running efficiently, too.
Manufacturers are continuing to search for more reliable ways to prevent the condensation/fog problem in glass door units. Exhibitors at the Food Marketing Institute (FMI) and National Restaurant Association (NRA) expos showcased some of the newest trends in these units.
The American Society of Heating, Refrigerating, and Air-Conditioning Engineers Standard 34 subcommittee has assigned a designation of R-422A to an HFC refrigerant that ICOR International has been marketing since the first of the year as One-Shotâ„¢.
