Fugitive Emission Characteristics of HFC-134a from Reefer Container

Modular simulation of reefer container dynamics

The amount of food transported long distances in reefer containers is constantly increasing and so is the cost per mile because of rising fuel prices. One way to reduce the cost is to minimize the energy consumed by reefer containers through a better controller but in order to achieve this a fast and flexible simulation model is needed for controller development. The simulation model may also b...

Development of HFC-134a Compressor for Domestic Refrigerator

Experimental Study on Journal Bearing Characteristics in Reciprocating Compressors for HFC-134a

This paper describes the experimental characteristics of cantilever type journal bearings in reciprocating compressors for HFC-134a. The purpose of this study is to compare the effects of bearing material, chemically treated shafts, bearing stiffness and refrigerant solubility in the oil to the characteristics of journal bearings lubricated with a mixture ofHFC-134a and lubricating oil As a res...

New Type Lube Oil for HFC-134a Compressor System

In order to find proper lubricants for HFC-134a compressor system, many polar compounds have been synthesized and evaluated. Among such compounds, polyalkylene glycol (PAG) derivatives and carboxylates (esters) have been identified as candidates for car air· conditioners and for refrigerators respectively.',.') However, it is dear that these amdidates have weaknesses: PAGs • demonstrate poor mi...
