The nozzle array and manifold is easily installed as a refit with the water control and weather center generally located adjacent to the air filter package. the AAF highpressure system employs stainless steel throughout for long life and minimum maintenance. this includes spray nozzles, pumps, pipe-work and fittings. CHILLERS Mechanical Chillers Refrigerant vapor is compressed using a screw, reciprocating, or centrifugal compressor. After compression, the vapor passes through a condenser. The condensed vapor is then expanded to provide the cooling effect. The evaporator chills the cooling water, which is circulated to the gas turbine inlet cooling coils. Either Ammonia or HFC-134a can be used as the refrigerant. Single Source Supply AAF, in conjunction with its sister company McQuay, markets a full range of refrigeration systems including Mechanical and Absorption Chillers. Inlet air is normally cooled by passing it through a finned coil (of tubes) and the air temperature must not be less than 5°C (41°F) to avoid ice formation on the coil. Refrigeration will always provide the design inlet temperature regardless of the ambient conditions, unlike the evaporative systems which lose effectiveness in high humidity conditions. AAF-McQuay offers an Ammonia Chiller with direct chilling of the air, without the chilled water circuit and also supplies an HFC-134a product which has a chilled water secondary circuit.
