New Products for HVAC and Refrigeration

Refrigerant retrofit bulletin, energy management guidelines, glycol unit coolers and wireless gas detection.


Refrigerant bulletin provides guidelines for refrigerant changeover from HCFC R-22 to HFC R-422A and HFC R-422D. The bulletin, "Refrigerant Changeover Guidelines %%MDASSML%% HCFC R-22 to HFC R-422A/D," is for Copeland Discus compressors and is part of the manufacturer's ongoing stewardship campaign to promote environmentally responsible refrigerant solutions.

Energy management guidelines detail the cost impact of wasted energy in industrial buildings and processes, and explains the solution steps to reduce the energy component of manufacturing costs. The presentation shows how when energy costs are treated as a component of cost-of-goods-sold, it becomes easier to understand the importance of managing the cost, much like labor or raw materials.

Glycol unit cooler product lines support a growing demand for secondary loop refrigeration systems in supermarkets. A supermarket may contain up to 5,000 lbs. of refrigerant circulating through walk-in coolers and display cases, and experience leak rates of up to 30%. In addition to harming the environment, these leaks negatively impact the profitability of supermarkets, as it is costly to clean up and replace lost refrigerant. A secondary loop refrigeration system uses glycol as a secondary fluid to cool the supermarket refrigerated spaces that may come in contact with food. Glycol is non-toxic, non-flammable and does not contribute to global warming. For more information about systems from Heatcraft Refrigeration, click here .

Wireless gas detector is designed to monitor carbon monoxide and nitrogen dioxide in parking structures. In contrast to traditional hardwired gas detectors, the device is said to offer significant installation, maintenance and energy savings, plus greater operational flexibility and reliability. Advantages include no wires, conduit or extra materials; automatic configuration upon activation; and hot-swappable, plug-in cartridge. For more about the 301W detector from Honeywell, click here .
