Review of ejector design parameters and geometry for refrigeration and air conditioning application
[EXTERNAL] Abstract: In this paper, a thermodynamic model of the ejector-expansion transcritical CO2 refrigeration cycle is developed.The basic transcritical CO2 systems exhibit low energy efficiency due to their large throttling loss. Replacing the throttle valve with an ejector is an effective measure for recovering some of the energy lost in the expansion process. The effect […]View
Making Refrigeration More Efficient with LPA®
HY-SAVE® technology delivers significant energy savings that pay back promptly by making refrigeration more efficient. For DX applications considerable savings can be made, generally up to 40%, ambient temperatures permitting. By simply reducing the condensing temperature from 32°C to 18°C it will provide a saving of approximately 23%. As energy costs continue to rise, the […]View
How to Convert R22 to MO99 Refrigerant Retrofit Guide
Summary – Steps to Retrofit
The following provides a summary of the basic retrofit steps for ISCEON® MO99.
(Detailed discussion of each step is provided in this bulletin.)
1. Establish baseline performance with existing refrigerant. (See retrofit checklist (attached))
2. Remove all the old (R22 or other) refrigerant from the system into a recovery cylinder. Weigh the amount removed.
3. Replace the filter drier and critical elastomeric seals/gaskets.
Refrigeration energy savings need not be expensive
Refrigeration energy saving need not be expensive. Energy savings of upto 20% can be realised in many refrigeration plant throughactions that require little or no investment.In addition, improving the efficiency and reducing the loadon a refrigeration plant can improve reliability and reducethe likelihood of a breakdown.View
