A direct fired absorption chiller is combined with a microturbine engine that operates to power another medium includes a by-pass valve interconnecting the discharge end of the recuperator and the discharge end of the turbine so as to maintain a constant heat delivered to the chiller. A temperature monitoring sensor actuates the by-pass valve to assure that the proper heat is maintained in the chiller. In the preferred embodiment the microturbine powers an electrical generating system.

1. A microturbine engine in combination with a direct fired absorption chiller comprising a turbine, a combustor, a compressor and a recuperator, said combustor fluidly connected to said compressor for firing fuel and creating an engine working medium, said turbine being powered by said engine working medium and producing exhaust of said engine working medium, said exhaust being delivered to said recuperator for placing the air discharging from the compressor in indirect heat exchange, and producing recuperator exhaust, said direct fired absorption chiller being fluidly connected to said recuperator exhaust, a bypass valve disposed between the discharge end of said turbine and the discharge end of said recuperator for selectively mixing the turbine exhaust with the recuperator exhaust prior to being delivered to said direct fired absorption chiller, directing all of the turbine exhaust into said recuperator so that only the recuperator exhaust is being delivered to the direct fired absorption chiller, directing all of the turbine exhaust to the direct fired absorption chiller, a controller controlling the bypass valve such that the heat flowing to said direct fired absorption chiller is at a constant predetermined value. 2. A microturbine engine in combination with a direct fired absorption chiller as claimed in claim 1 including a temperature sensor operatively connected to said water chiller for measuring the temperature of the water therein and an actuator operatively connected to said temperature sensor for controlling said by-pass valve.3. A microturbine engine in combination with a direct fired absorption chiller as claimed in claim 2 including an alternator for generating electricity, said microturbine engine operatively connected to said alternator for rotating said alternator.
