While striving to support cost effective( both initial & operating) and energy efficient ecofriendly green refrigeration systems, it is time we adopt the attitude of Can-Do credo by switching from traditional two-stage compound ammonia refrigeration system to hyper cascade system. We may all want to keep track and embrace this system which has already attained […]
BY MANUCHEHR MEHDIZADEH, BSME LIFE TIME MEMBER ASHRAE, COMMITTEE OFFICER @ IIR, REFRIGERATION CHAIR @ ASHRAE HOUSTON CHAPTER Ammonia Refrigeration Basics Refrigeration systems use basic physics to transfer heat energy out of one area and into another, leaving the first area cooler than it was before as in the cold store systems. Various ice production […]

The risks involved with ammonia refrigeration are substantially reduced by EPA’s Risk Management program (RMP) and preventive maintenance. Part of that process is clear labeling of incorporated pipes and equipment. As the accepted industry experts in this field, the IIAR maintains a code of recommendations for refrigeration equipment labeling- Manuchehr Mehdizadeh, BSME Project Advisor-All aspect of […]
