Practical Refrigeration System Design – Natural Refrigerants for Every Application

Refrigeration System Design | Heat and Mass Transfer Solutions | Bruce V. Nelson EngineeringBVN Engineering can assist you with the design of heating and cooling systems, and machines which make use of the natural refrigerants ammonia (R717), carbon dioxide (R744), propane (R290), propylene (R1270), iso-butane (R600a), air (R729), and water (R718). Low charge direct expansion ammonia systems offer customers safe, environmentally friendly, high efficiency heat pump and refrigeration system design.

CO2 (carbon dioxide) has become increasingly popular as a refrigerant in transcritical refrigeration systems, subcritical cascade refrigeration systems, and in heat pumps due mainly to its unregulated status. CO2 is low cost, environmentally friendly, non-toxic, and non-flammable.

The hydrocarbons, such as propane, propylene, and iso-butane make excellent refrigerants for all types of refrigeration and heat pump systems. Flammability of the hydrocarbons is obviously a safety concern, however, in small, packaged machines with low charge levels, they offer safe, low cost, energy efficient solutions. Operating pressures and energy efficiency for the hydrocarbons are similar, or better, compared to the synthetic halocarbon (HCFC, HFC) refrigerants. This, in addition to good compatibility with the materials used in common commercial air-conditioning and refrigeration systems makes hydrocarbon refrigerants an attractive low first-cost solution.

The engineers at BVN Engineering can help you evaluate how best to apply natural refrigerants to achieve the environmentally-friendly, safe, energy efficient solutions you want to achieve.
