Benefits of technology
"The present invention provides a spot cooling system for open boats that uses an air conditioner with a closed system and refrigerant. The system includes a cooling water pump, a compressor, a condenser, an evaporator, and pressure-regulating means. The system also includes drying means and air moving means. The air moving means includes a blower and ducts for directing air towards the seats in the open cockpit. The technical effect of the invention is to provide efficient cooling for open boats while maintaining a comfortable environment for the occupants."
Problems solved by technology
However, cooling has not been available to occupants of open boats heretofore.
Operating an open boat in hot weather presents discomfort, and in some cases, health problems as well.
A system using an orifice requires an accumulator downstream of the evaporator to trap liquid, which would destroy the compressor.
This places changing loads on the engine, thereby causing the RPM to change with the load.
The resulting speed fluctuations are unacceptable in water sports.
On a practical basis however, the Brunner system neither shows nor suggests a drying device, and is therefore left vulnerable to compressor damage.
The ice is heavy, bulky, and short-lived.

Embodiment Construction
[0027]Referring now to the drawing, and especially to FIGS. 1 and 3 thereof, a spot cooling system for open boats is shown at 10 and is for use in connection with a boat 12 having an open cockpit 14 with seats 16, a hull 18, and an engine (not shown). The engine has a cooling system and a cooling water pump 20 driven by the engine. The cooling system has a cooling water inlet 22 and a cooling water outlet (not shown). Cooling water flow is indicated by arrows 24.
[0028]The spot cooling system is an air conditioner having a closed system and a refrigerant, as described above. A compressor 26 is driven by the engine for compressing the refrigerant. The compressor 26 has a compressor inlet 28 and a compressor outlet 30. Refrigerant flow is indicated by arrows 74.
[0029]A condenser 32 is provided for condensing the refrigerant. The condenser 32 includes a fluid-tight housing defining a first passage, which is a cooling water passage 36. The condenser 32 includes at least one conduit withi...

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.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Not ApplicableSTATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not ApplicableBACKGROUND OF THE INVENTION[0003]This invention relates to the field of air conditioners, and more particularly to an air conditioning system that cools individual occupants in an open boat, rather than an enclosed room.[0004]Air conditioners for cooling the internal volume of an enclosed room or cabin are well known, and in common use in buildings, cars, and boats. However, cooling has not been available to occupants of open boats heretofore. Operating an open boat in hot weather presents discomfort, and in some cases, health problems as well. Drivers and crew have experienced heat stroke in extreme cases.[0005]Conventional boat air conditioners will typically comprise a closed system having a refrigerant, such as R12 (freon©) or R134a. The system is divided into two sides, a high pressure or discharge side, and a low pressure or suction side...
