Résumé :
|
An auxiliary mixed refrigerant cycle for subcooling of a liquid refrigerant in the main cycle can provide up to 40% increase in the coefficient of performance of a conventional vapor compression cycle. This is twice as efficient compared to the conventional mechanical subcooling. In addition, an increase in the cooling capacity of up to 100% can translate into a reduction in the size of the whole system by up to 30%.This auxiliary precooling system can be built using mass produced components. The relatively small size of the unit makes it possible to use a packaged design compatible with mixed refrigerants. Experimental test data prove the proposed new system concept.
