One exemplary embodiment of this invention provides a single-effect absorption chiller including an absorber operatively connected to a solution heat exchanger and a generator, and a condenser in fluid communication with the absorber, wherein the absorber is sized and configured to receive a feed of water from a source of water and to transfer heat to the feed of water and then to convey the feed of water to the condenser without further heat conditioning of the feed of water prior to its entry into the condenser, and wherein the condenser is sized and configured to receive the feed of water from the absorber and to transfer heat to the feed of water, thereby cooling the condenser without resorting to an external heat exchanger such as a conventional cooling tower.

1. A single-effect absorption chiller, comprising: an absorber operatively connected to a solution heat exchanger and a generator, anda condenser in fluid communication with the absorber, wherein the absorber is sized and configured to receive a feed of water from a source of water, and to transfer heat to the feed of water and then to convey the feed of water to the condenser without further heat conditioning of the feed of water prior to its entry into the condenser, and wherein the condenser is sized and configured to receive the feed of water from the absorber and to transfer heat to the feed of water, thereby cooling the condenser and further comprising a heat exchanger component of the generator, wherein the heat exchanger component of the generator is sized and configured to receive the feed of water from the condenser and to transfer heat to the feed of water from an external heat source. 2. A single-effect absorption chiller, comprising: an absorber operatively connected to a solution heat exchanger and a generator, anda condenser operatively connected to a heat exchanger component of the generator,wherein the condenser is sized and configured to receive a feed of water from a source of water and to transfer heat to the feed of water and then to convey the feed of water to the heat exchanger component of the generator, which heat exchanger component transfers heat to the feed of water from an external heat source. 3. A system comprising: a combustion engine, a single-effect absorption chiller according to claim 2, an engine inlet chiller operatively connected to at least the combustion engine, and a conduit for conveying chilled water from the absorption chiller to the engine inlet chiller, the foregoing being sized and configured so that, during use, waste heat released from the combustion engine powers the generator of the single-effect absorption chiller, which single-effect absorption chiller produces chilled water, and the system being sized and configured to circulate at least a portion of the chilled water through the conduit to the engine inlet chiller to cool air entering the combustion engine. 4. A system comprising: a combustion engine, an absorption chiller according to claim 2, an engine inlet chiller operatively connected to at least the combustion engine, and a conduit for conveying chilled water from the absorption chiller to the engine inlet chiller, the foregoing being sized and configured so that, during use, waste heat released from the combustion engine powers an internal generator of the absorption chiller, which absorption chiller produces chilled water, and the system being sized and configured to circulate at least a portion of the chilled water through the conduit to the engine inlet chiller to cool air entering the combustion engine. 5. A method comprising: a. providing a refrigerant vapor to an absorber of a single-effect absorption chiller in which at leasti. the refrigerant vapor contacts an incoming condensed absorbent stream from a solution heat exchanger,ii. the refrigerant vapor is absorbed by the condensed absorbent stream to form a liquid diluted solution mixture, andiii. a water stream from a source of water is provided to cool the absorber to make a high affinity between the refrigerant vapor and the condensed absorbent stream during the absorption process in (a)(ii) and to transfer heat to the feed of water;b. providing the water stream from the absorber to a condenser so that the water stream absorbs at least a portion of released latent heat from the condenser, thereby forming a condenser-heated water stream and cooling the condenser; andc. further heating the condenser-heated water stream by feeding it into a generator through a heat exchanger component wherein the condenser-heated water stream absorbs additional heat from energy from an external heat source. 6. The method of claim 5 further comprising: d. providing a second water stream into an evaporator in which a low-temperature, low-pressure refrigerant flashes into vapor and absorbs heat from the second water stream, thereby lowering the temperature of the second water stream and forming a chilled water stream. 7. The method of claim 6 further comprising: e. transferring at least a portion of the chilled water stream to an engine inlet chiller operatively connected to a combustion engine, andf. circulating exterior air through the engine inlet chiller. 8. A method comprising: a. providing a refrigerant vapor to an absorber of either a single-effect or a multi-effective absorption chiller in which at least i. the refrigerant vapor contacts an incoming condensed absorbent stream from a solution heat exchanger,ii. the refrigerant vapor is absorbed by the condensed absorbent stream to form a liquid diluted solution mixture, andiii. a water stream from a source of water is provided to cool the absorber to make a high affinity between the refrigerant vapor and the condensed absorbent stream during the absorption process in (a)(ii) and to transfer heat to the feed of water;b. providing the water stream from the absorber to a condenser so that the water stream absorbs at least a portion of released latent heat from the condenser, thereby forming a condenser-heated water stream and cooling the condenser; andc. further heating the condenser-heated water stream by feeding it into a generator through a heat exchanger component wherein the condenser-heated water stream absorbs additional heat from energy from an external heat source.
