Innovators in Energy Conservation

Global Cooling - The Netherlands

Global Cooling Inc. is a Delaware USA, based corporation with two, wholly owned subsidiaries; Global Cooling BV and Global Cooling Manufacturing. Global Cooling BV, with headquarters in The Netherlands, was brought into existence in 1994 when it purchased a license for free-piston Stirling refrigeration technology developed by Sunpower of Athens, Ohio. Global Cooling Manufacturing Co., with headquarters in Athens, Ohio, was established in 1995 for the purpose of developing and producing Stirling Coolers for commercial and consumer applications.

pROBLEM TO BE SOLVED

Stirling coolers will dramatically reduce the energy consumption and environmental impact of refrigeration. Despite the expectations and promises of current refrigerants, particularly the hydroflourocarbons (HFC’s) like R134a, it has been demonstrated that these refrigerants still have a detrimental affect on the environment. The Free Piston Stirling Cooler (FPSC) technology incorporated into products by Global Cooling and its licensees uses only natural working fluids (helium) and operates at high efficiencies, providing a fundamental advantage over competing systems.

Self Contained Low Temperature Petroleum Analyzer

Global Cooling’s free-piston Stirling has several unique benefits over conventional refrigeration systems. While current domestic refrigerators have a Rankine-cycle cooling system, driven by a motor-compressor, in a Stirling refrigerator this system would be replaced by a Stirling-cycle cooling system. Rankine systems show a characteristic decrease in efficiency as the demand for cooling decreases, e.g. when the refrigerator is maintaining a cold condition. However, Free Piston Stirling Coolers (FPSC’s) retain their high efficiency regardless of the demand for cooling because they can fully modulate their capacity to match the required load. In addition, the FPSC system requires no environmentally damaging CFC's, HCFC's, HFC's, or dangerous hydrocarbons (butane, for example). Operationally, the FPSC is able to work efficiently at far higher and far lower temperatures than conventional equipment, making it ideal for new or otherwise impractical cooling and heat transport problems.

eNERGY/ENVIRONMENTAL/ECONOMIC BENEFITS

Global Cooling's FPSC, with its ability to fully modulate cooling capacity to match demand, is much more energy efficient than conventional Rankine systems which can only turn on and off. GCBV submitted a design for a portable refrigerator to the judging committee of the Maltha Environmental Award in 1995 and was awarded First Prize. Today this concept has been commercialized in the form of a 25 liter consumer portable refrigerator/freezer manufactured by Twinbird Corporation of Japan.
