About the authorMike Fisher has over 35 years of experience with refrigeration systems. This background includes; service, installation, equipment manufacturing, research and development, project management, consulting engineering, system design and packaged systems.
By now many of the States in the upper midwest have experienced very cold weather. As some have found, winter time presents some occasional challenges for starting or operating an ammonia refrigeration system.
What impact does location have on your energy use? Obviously, if you are located in the South or Western part of the US your ambient temperatures (wet bulb or dry bulb, depending on condenser type) will be higher year round. This can limit your efforts to lower the discharge pressure.
