With the continued push to reduce energy consumption in both the US and abroad the discussion about the feasibility of utilizing heat pumps in the United States has begun to heat up. Traditionally the refrigeration industry has been most interested in the low-pressure cold side of the refrigeration process, but what about all the energy …
The focus this month is a brief look at the American Innovation and Manufacturing act or AIM act for short. This policy seeks to dramatically reduce the usage of HFC refrigerants with the target of a 85 percent reduction by 2036. The goal of the policy is to reduce the amount of refrigerant with high …
Hydrocarbons such as Propane, Propylene, and Isobutane are great natural refrigerants that are successfully used in commercial refrigeration appliances today. Hydrocarbons can boast the low global warming potentials regulators are looking for without being Ozone depleting. So why don’t they get as much airtime as other natural refrigerants such as ammonia and CO2? Perhaps the …
An important part of the refrigeration design process is determining what size refrigerant lines returning to a compressor or an accumulator/recirculator vessel should be. These return lines are often simply called suction lines and are sized based on the tonnage of the refrigerated load. Recommended pipe size will change based on tonnage as well as …
If you have ever been involved in buying or installing a new evaporatively cooled condenser, then you’ve probably heard about evaporative condenser passivation. You probably heard it is important and a process you should strive to complete. But if you are like many owners, operators, or heck even refrigeration engineers, that’s probably where your knowledge …
Secondary Refrigerants Are Worth A Second Look All refrigeration systems, at their very core, convert electrical energy into heat removal potential. Primary refrigerants typically do this via the refrigeration cycle of compressing, condensing, expanding and evaporating. Secondary refrigerants typically transfer heat from place to place without changing phase. Volatile secondary refrigerants are the exception to …
Staying Cool – Basic Heat Loads by Jayson Noetzelman When it comes to refrigeration, Carlson & Stewart is in the business of helping you stay running and stay cool, but even a system running perfectly might not always be as cold as you’d like. What can be done to improve your situation? A business owner …
