Applications of Industrial Ammonia Heat Pumps with Single Screw Compressor Technology
Advances in screw compressor technology have enabled the development of high temperature ammonia heat pumps for use in industrial applications. The balanced axial and radial design of the single screw compressor allows for operation at significantly higher pressures and higher differential pressures than required for industrial refrigeration duty. The high pressure capability of single screw technology, overcomes the mechanical limitations of older screw technology, permitting the conversion of waste heat from a variety of industrial ammonia refrigeration applications into useable heat at temperatures up to 90°C (194°F).
