Several leading companies including Mayekawa will be presenting their innovative natural-refrigerant technology case studies at the 2nd annual ATMOsphere Asia 2015. Mayekawa’s presentation will focus on the generation of hot water via an ammonia heat pump using the rejected heat of a refrigeration system.

The ATMOsphere Review Board has announced the case studies selected for presentation at ATMOsphere Asia 2015, which will take place from 3-5 February in Tokyo, Japan. Motobumi Ono, from Mayekawa Australia, will showcase one of his latest projects using ammonia as the refrigerant.

Modern industrial refrigeration systems typically consist of single and/or multi stage ammonia compressors to provide cooling solutions for numerous applications and processes. More often than not, the heat absorbed from within the refrigerated space, plus the heat of compression is rejected to the atmosphere via an air, evaporative or water cooled condenser. With the current and ongoing environmental challenges and the global expectation of improving energy efficiency, rejecting such a large amount of heat without utilization can be deemed as wasteful.

A large number of industrial refrigeration system users often require large quantities of hot water for either wash down, boiler make up, or CIP processes. The presentation will focus on generating useful hot water via an ammonia heat pump, rather than rejecting the refrigeration system heat. This offers an energy efficient method of useful and sustainable hot water generation for many industries.

Other case studies that will be presented at the conference include:
