Abstract: An addition to the air compressor of a combustion turbine system is disclosed, which chills the inlet air on warm days. The same equipment with minimal modification is used to prevent inlet air icing conditions on cold days. Referring to FIG. 1, inlet air conditioner heat exchanger 3 supplies conditioned (chilled or heated) air to the combustion turbine, and heat recovery unit 1 supplies turbine exhaust heat to ammonia absorption refrigeration unit 2. Control valves 5, 6, 7, and 8 selectively supply either chilling refrigerant liquid or heating vapor from AARU 2 to conditioning heat exchanger coil 3.

Abstract: An improvement to the air compressor of a combustion turbine system is disclosed, which makes the air compression more energy efficient plus have higher capacity on warm days. The same equipment with minimal modification is used to prevent inlet air icing conditions on cold days. Referring to FIG. 1, inlet air conditioner 3 supplies conditioned (chilled or heated) air to the combustion turbine, and heat recovery unit 1 supplies turbine exhaust heat to ammonia absorption refrigeration unit 2. Control valves 5, 6, 7, and 8 selectively supply either chilling refrigerant liquid or heating vapor to conditioning coil 3.

Abstract: An absorption power cycle is disclosed which achieves a closer match to heat source temperature glide, and also lower heat source exit temperatures, and hence higher conversion efficiencies, in practical equipment. Referring to FIG. 7, two separate absorbers (725 and 706) are provided, each with a pumping path for a different concentration absorbent liquid to a different temperature location within counter-current high-pressure desorber 721. Heat source 710 heats the high-pressure desorber 721 and superheater 724 in parallel, and subsequently heats intermediate-pressure desorber 761. Dotted lines in the figures signify vapor.

Abstract: Apparatus and process are disclosed for increasing the efficiency of thermally actuated absorption process such as absorption compression and absorption heat pumping. The improvement allows greater temperature overlap between generator and absorber, ambient responsive performance, significantly lower need for rectification, multiple temperature level refrigeration, and hybrid operation. Referring to FIG. 2, the useful result is obtained by routing the sorbent from the externally cooled absorber (10) to a sub-ambient absorber (2) and further cooling and diluting the sorbent by means of the evaporator (28). The sorbent is concentrated in the absorber-heated generators (14 and 18) and the externally heated generator (22).
