Aire Serv Heating & Air Conditioning Inc. contractors had the opportunity to snorkel in and parasail over the deep blue waters of the Gulf of Mexico during their Fall Conference 2002 in Cancun. They also attended a number of idea-sharing seminars.
It was lights, camera and action recently as www.hvacchannel.tv brought a live broadcast over the Internet to subscribers from a small studio tucked in the rear of an inconspicuous office building in suburban Atlanta. The occasion was a series of HVACR industry updates.
Jim Shell put a simple question to attendees during his seminar on zoning at the Texas Chapter of the Air Conditioning Contractors of America (TACCA) 2002 Fall Conference. “Why zoning?” he asked. “The simple answer is people are uncomfortable at home and at work,” said Shell.
The Texas Chapter of the Air Conditioning Contractors of America (TACCA) kicked off its 2002 Fall Conference with a speech from a familiar Texas face. Daryl Johnston, former running back for the Dallas Cowboys and current TV broadcaster for Fox Sports, spoke about “Opportunities for Success.” Johnston should know a little about success, having played on three Super Bowl-winning teams.
Taking shortcuts while servicing refrigeration equipment can lead a technician to make costly mistakes. Not only can these mistakes be expensive; they can also cause harm to the equipment, as well as the technician.
The industry has developed multiple lengths of transducer-type liquid level probes for use with halocarbon refrigerants. Such controls are often focused directly on supermarket racks. The application supports monitoring, performance, and charge management, as well as troubleshooting, via a central microprocessor-based control panel.
In current designs, the electronics controlling the valve are separate from the valve itself. The correct term is therefore electronically controlled electric valves. Since electric valves are assigned their function in the system by the software in their controller, an electric valve can be used anywhere in the system — as an expansion valve, discharge gas bypass valve, evaporator control valve, heat reclaim valve, head pressure control valve, or crankcase pressure control valve. Several designs have evolved to meet different applications.
Modern supermarkets offer fresh fruits, vegetables, meats, and seafood, often from distant locations. Rapid refrigerated transport ends up being an important part of the food delivery equation. Once fresh food products leave the farm or the processing plant, proper temperature control is essential.
