Embodiment Construction

[0047] Now, the invention is described based on the accompanying drawings, which do not limit the scope and bounds of the invention. The description is provided entirely by way of example and illustration.

[0048] The present invention contemplates a hybrid absorption-compression refrigerator that includes a vapor compression system that provides refrigeration in a primary evaporator by absorbing heat from the object to be cooled by condensing a primary coolant, where the condensing primary The coolant is usually selected from tetrafluoroethane (R134a), dichlorotrifluoroethane (R123), trifluoroethane (R143a) and carbon dioxide (R744); also contains a vapor absorption system which is compatible with Vapor compression systems are operatively communicated through compressors to receive primary coolant vapors, which are cooled by condensed secondary coolant, typified by water, to provide condensed primary coolant that will be circulated to the vapor compression system. The prese...

Abstract

The present invention envisages a hybrid absorption-compression chiller comprising: a vapor-compression system providing a refrigeration effect in a primary evaporator (102a) by extracting heat from a medium to be cooled in a condensed primary refrigerant, and a vapor-absorption system in operative communication with the vapor-compression system for receiving primary refrigerant vapors via a compressor (104a), these vapors are cooled by a condensed secondary refrigerant in a secondary evaporator (106a) to provide cold condensed primary refrigerant which is recycled to the vapor-compression system. The hybrid absorption-compression chiller of the present invention is energy-efficient and provides a higher (coefficient of performance) COP in comparison with the conventional chillers.

Description

technical field [0001] The invention relates to a hybrid absorption-compression refrigerator for providing refrigeration. Background technique [0002] Refrigeration processes are widely used in industries such as: liquefying oxygen, nitrogen, propane and methane, purifying compressed air from moisture, maintaining low process temperatures in oiling, petrochemical, chemical processes, and tempering metals in the metallurgical industry. Refrigeration equipment, which is usually used to achieve refrigeration, widely uses vapor compression or vapor absorption. These devices use liquids or salts to absorb working fluid vapors and effect heating or cooling. [0003] Vapor absorption chiller devices are thermally driven, meaning that heat from waste sources or solar collectors is used to drive the cycle rather than mechanical energy; however, vapor absorption chiller devices use mechanical input of higher energy (electrical energy). Therefore, the basic difference between absorp...
