Freeaire Refrigeration System and Cool Breeze Outside Air Package

The Basic Freeaire Refrigeration System utilizes an electronic controller to optimize energy-efficiency and to extend the service life of commercial walk-in coolers and other refrigeration equipment in any climate by running all the equipment—condensing fans, compressors, evaporator fans, and glass door "heaters"—only as much as is needed… Read more

  • With energy-consuming equipment, such as water heaters and refrigerators, we have good data on energy consumption and can set clear standards accordingly. In some product categories—clothes washers, for example—Energy Star standards were adopted because those standards provide a high enough threshold to represent just the very top segment of the product market (less than 10%). In other product categories—e.g., refrigerators and dishwashers—we set a higher threshold than ENERGY STAR: for example, exceeding those standards by 10% or 20%. With lighting and lighting control equipment, certain generic products qualify, such as compact fluorescent lamps and occupancy/daylighting controls, while in other categories only a subset of products qualify. In some cases, products that meet the energy efficiency requirements are excluded, because of evidence of poor performance or durability. Microturbines are included here because of the potential for cogeneration (combined heat and power) that they offer.

The Basic Freeaire Refrigeration System utilizes an electronic controller to optimize energy-efficiency and to extend the service life of commercial walk-in coolers and other refrigeration equipment in any climate by running all the equipment—condensing fans, compressors, evaporator fans, and glass door "heaters"—only as much as is needed. For example, evaporator fans, which are usually running constantly, might operate 50–75% less. For refrigeration equipment in cold climates, the Cool Breeze Outside Air Package uses cool outdoor air to supplement mechanical cooling or even replace it entirely during winter months. This offers dramatic energy savings and can extend the service life of equipment. Worksheets are available to calculate potential energy savings, which can be significant—often times providing a payback period of less than two years, according to the company.

Products listed here include innovative commercial refrigeration equipment, e.g., for walk-in coolers, that save energy by using outside air, or optimizing performance on other ways.
