Abstract: A spot cooling air conditioner system is for open boats having an open cockpit with seats. A refrigerant compressor is driven by the engine. A condenser includes a cooling water passage and a refrigerant passage in thermal communication. The condenser cooling water is supplied by the engine water pump. An evaporator includes an air passage and a refrigerant passage in thermal communication. Pressure-regulating means is an orifice tube. Drying means includes an accumulator. The compressor, condenser, and evaporator refrigerants are connected. The orifice tube is connected between the condenser and the evaporator. The accumulator is connected between the evaporator and the compressor. Air moving means includes a blower connected to the evaporator air passage. A plurality of ducts is connected to the evaporator. The ducts selectively direct cooled air toward the seats in the open cockpit, thereby spot cooling passengers in the open cockpit.
