There are many things I’d like to tell you about the 2013 AHR Expo held in Dallas in late January, but the message about refrigerants is so urgent that it pre-empts my regular show coverage (which will follow in the April issue of Supply House Times).
Everyone knows when natural gas is not available (in many Northeast buildings, much of Florida and rural areas), the least-expensive form of heating is the heat pump.
However, among many people heat pumps have a terrible reputation for blowing cold air.
Has it come to this? Well,
not yet, but possibly soon! I recently read an article telling of how some
companies are marketing a hydrocarbon refrigerant to replace R-22 in air
conditioners, and they are marketing it to consumers, not HVACR supply
houses.
Our industry talks a lot
about indoor air quality, and whenever engineers design a commercial,
institutional or industrial building, great care is usually taken to ensure
proper air movement and ventilation.
