摘要： The present invention envisages a hybrid absorption-compression chiller comprising: a vapor-compression system providing 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 COP in comparison with the conventional chillers.

摘要： An apparatus for providing heating and/or refrigeration effect and a method thereof is disclosed which provides simultaneous heating and refrigeration, only heating or only refrigeration, using a double-effect vapor absorption cycle or a single-effect vapor absorption cycle. The present invention comprises providing a heat input to an absorbent in a generator to obtain a concentrated absorbent which is fed to a set of absorbers which are located in co-operation with a set of evaporators provided with a condensed refrigerant, to obtain heating and/or refrigeration effect. The heat/energy used during the process is recovered by a plurality of heat exchangers such that the wastage of energy and utilities is minimized. The present invention substantially reduces the CO2 emissions, thus is eco-friendly.

摘要： A triple-effect vapor absorption refrigeration system is disclosed. The system comprises a high temperature generator, a medium temperature generator, and a low temperature generator, for concentrating a dilute Li—Br solution from an absorber, through a flow path from the high temperature generator to the low temperature generator via the medium temperature generator. In the system maximum Li—Br solution temperature and maximum Li—Br solution concentration does not occur simultaneously, hence, Li—Br corrosion rate is reduced and minimum non-condensable gases are generated, this helps in maintaining vacuum during operation thus providing a smoother operation.

摘要： The absorption chiller-heater apparatus of present invention utilizes a portion of direct heat, used to heat water, for providing the refrigeration effect. The external heat input required for providing refrigeration is minimal; hence, the efficiency of the apparatus is increased by 30-40% over the conventional systems. Further, as the quantum of the external heat source required for a new cycle is reduced, the size of the high temperature generator required, is smaller, which results in lower capital costs. The apparatus provides chilled water which can be used for various industrial purposes. The absorption chiller-heater reduces CO2 emissions and utilizes a single arrangement to produce both heating and refrigeration effect. Thus, additional electrical and heat input or separate components are not required.
