A Compact Horizontal Scroll Type Compressor for Room Air Conditioners

This paper presents the construcrion, newly developed design technologies and performance characteristics of a compact horizontal scroll-type compressor for room air conditione~:s. The authors were able lo develop a compacl variable speed horizontal scroll-type compressor with a cooling capacity of I. 8 kW, which necessitated the development of new mechanisms, namely, an alCial compliance mecha...

High Efficiency Compact Rotary Compressor Using the New Refrigerant HFC-134a for Automotive Air Conditioners

In accordance with worldwide consensus, the use of chlorofluorocarbons, which play an important role in damaging the ozone layer, should be completely abolished by the end of 1995. This provided the impetus for developing the three vane rotary compressor. Formerly CFC-12 was used as the refrigerant in automotive air conditioners, until HFC-134a was substituted for CFC-12. In response to the cha...

EER Improvement for Room Air-Conditioners in Saudi Arabia

This paper demonstrates the possibility of achieving a higher Energy Efficiency Ratio (EER) for Room Air Conditioners (RACs) that complies with the Saudi energy efficiency standards and satisfies the energy conservation requirements for the Saudi Building Code (SBC). This study considers several design options for improving the performance and efficiency of the RAC in comparison with a baseline...

The Design of a Small Oil-Flooded Rotary Air Compressor

There have in the past been few successful small oil flooded rotary air compressors, due in the main to the cost of manufacture and the problem of internal condensation with intermittent operation. The paper describes a new approach to overcoming these problems, and reports a successful outcome.
