Secondary Refrigerant Systems for Supermarket Application with Brine or Carbon Dioxide
The interest in application of secondary refiigerant systems in supermarket refrigeration is increasing. Reduced refrigerant losses i and the chance for lower installation and operation costs is promoting this development. There are also !options to use natural refrigerants, more efficient refrigerants and gas or waste heat driven absorption proc;esses. First installations of secondary refriger...
متن کاملNear Azeotrope Refrigerants to Replace R502 in Commercial Refrigeration
The Refrigerant RS02, an azeotrope of CFCllS and HCFC22, is an important refrigerant in commercial refrigeration, especially for low temperature applications using single stage compressors. current users of R502 are faced with an earlier than ~nticipated phase-out and are under great pressure to find suitable alternates for retrofit and o.E.M. (new) applications. Single components like HCFC12S,...
متن کاملAmmonia Low-Pressure Receiver Systems
Ammonia can be applied to any type and size of refrigeration system from domestic refrigeration to commercial refrigeration and air-conditioning to industrial refrigeration. However, it is desirable to minimize the charge to prevent toxic effects and, sometimes to use secondary refrigerants, such as volatile carbon dioxide, to keep ammonia away from the general public. This article describes a ...
متن کاملTesting of Environment Friendly Refrigerant R290 for Water Cooler Application (RESEARCH NOTE)
This paper presents environment friendly refrigerant R290 as a solution to the environmental concerns like depletion of ozone layer and rise in global warming because of wide use of synthetic refrigerants R22 and R134a. The water cooler is the widely used refrigeration application in warm climatic countries. Refrigerant R22 and R134a are predominantly used refrigerants in water cooler refrigera...
متن کاملComparison of Energy Efficiencies of Commercial Refrigeration Direct and Indirect Systems
Centralized commercial refrigeration is becoming a sector where several technical options are competitive. These options are evaluated based on three major criterions: energy consumption, refrigerant emissions and initial cost. In supermarkets with machinery rooms, the competition is strong between previous centralized direct systems and new systems using heat transfer fluids. To achieve balanc...
