The present invention envisages a hybrid absorption-compression chiller comprising: a vapor-compression system providing refrigeration effect in a primary evaporator () 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 (), these vapors are cooled by a condensed secondary refrigerant in a secondary evaporator () 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.

Hybrid absorption-compression chiller

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 COemissions, thus is eco-friendly.
