T/CCI's latest introduction to the CASE Construction product family is the QP7H15 150 cc displacement compressor fitted to the backhoe loader.
The company also has plans to develop a two-stage compressor and a larger displacement compressor.
com)-- T/CCI Manufacturing strategic alliance with CASE Construction recently produced the QP7H15 150 cc displacement compressor fitted to the CASE Construction backhoe loader.
This allowed the cooling requirement to be met with a smaller displacement compressor, reducing power usage.
The cement sector will also contribute significantly to the positive displacement compressor market's revenues, as the widening gap between supply and demand in this sector will lead to both greenfield and brownfield investments, boosting the demand for positive displacement compressors.
The VSM is a rotary, positive displacement compressor, which incorporates a main screw and two gaterotors.
For a positive displacement compressor, the compressor power is approximately proportional to the compressor speed.
Nouri is Assistant Dean, Diego Guerrato is a doctoral student, Nikola Stosic is Chair of Positive Displacement Compressor Technology, and Constantine Arcoumanis is Dean at the School of Engineering and Mathematical Sciences, City University, London, UK.
Since the required compressor displacement for HC-600a refrigerant is almost double that of HFC-134a to achieve identical capacity and since the larger bore size increases piston-cylinder clearance and a small displacement compressor increases re-expansion volume, raising volumetric efficiency in small refrigerating-capacity compressors is difficult.
Positive displacement compressors, such as the rotary screw, tended to dominate applications in the 100 to 300 tonne range.
