Many refrigeration systems are installed using an outdoor air-cooled condenser. When these systems are installed in a climate where the outdoor temperature drops below 60°F, some means of preventing the condensing pressure from dropping too low must be incorporated into its design.

When evaporation occurs in a cooling tower, only the water evaporates; it exits the cooling tower as water vapor, but leaves the minerals behind to concentrate in the cooling tower’s water system.

Hybrid sealants are drawing more attention from contractors and distributors. According to comments from within the industry solicited by Cliplight Manufacturing, which makes a variety of sealants, there is an interest for sealants that are a combination sealant, drying agent, and dye.

FROSTlines is an enewsletter specifically for those in the refrigeration sector, the ‘R’ in HVACR.

While changes are a natural part of the refrigeration business, there are some constants that remain the same, namely the importance of timely customer service, parts availability, and technical expertise.

The Horizon™ 1800 Series icemakers are designed to produce up to 1,580 pounds of ice in a 24-hour period.

Two refrigeration equipment manufacturers have received recognition for their energy efficiency efforts: Scotsman Ice Systems and Freeaire Refrigeration.

As hard as certain elements in Europe continue to push for a ban on f-gas refrigerants including HFCs, there is an equally strong push back by those who want any decisions based on a range of factors that could well keep HFCs in play for a long time.

Recent developments related to refrigerant research are focusing on testing of a new HC refrigerant and growing acceptance of a method of destroying unwanted refrigerants. In the first, ComStar International is providing test results on its blended hydrocarbon 188C2. In the second, Midwest Refrigerants is reporting on its destruction technology.
