Abstract

Abstract A novel delivery system for delivering a fine fog of water through a plurality of nozzles to absorb heat through evaporation. The delivery system comprises the combination of a water supply tank, an air compressor, solenoid valve and an electronic control module for controlling the operation of valve and compressor to allow an operator to adjust the displacement rate of fog as well as providing the operator a choice between continuous, intermittent and pulsing operation.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 157 words
An evaporative cooling delivery system for cooling the seating space within an open cabin vehicle comprising: a compressor for delivering air under pressure; a refillable reservoir which is connected to and positioned downstream of said compressor, the reservoir containing water; a plurality of nozzles downstream of said reservoir for dispersing said water as a fog directly into the seating space of said vehicle, the fog absorbing heat by evaporation; a valve disposed between said nozzles and said reservoir to control the displacement rate of the water from said reservoir to said nozzles; an electronic control module having the capability to measure parameters that are indicative of the displacement rate of the water from the reservoir; a power supply operatively connected to the compressor and the control module; and means to activate and adjust the delivery of water under continuous, intermittent and pulsing operation wherein said means adjusts the operation of said compressor and said solenoid valve accordingly.
Claim 2
Dependent Claim 157 words
An evaporative cooling delivery system for cooling the seating space within an open cabin vehicle comprising: a compressor for delivering air under pressure; a refillable reservoir which is connected to and positioned downstream of said compressor, the reservoir containing water; a plurality of nozzles downstream of said reservoir for dispersing said water as a fog directly into the seating space of said vehicle, the fog absorbing heat by evaporation; a valve disposed between said nozzles and said reservoir to control the displacement rate of the water from said reservoir to said nozzles; an electronic control module having the capability to measure parameters that are indicative of the displacement rate of the water from the reservoir; a power supply operatively connected to the compressor and the control module; and means to activate and adjust the delivery of water under continuous, intermittent and pulsing operation wherein said means adjusts the operation of said compressor and said solenoid valve accordingly.
Claim 3
Dependent Claim 20 words
The evaporative cooling delivery system of claim 1 further comprising a check valve disposed between said compressor and said reservoir.
Claim 4
Dependent Claim 139 words
An evaporative cooling delivery system for use in the cabin of an open air vehicle, the delivery system having operatively connected a power supply, refillable water reservoir, a supply of water in the reservoir, and a plurality of nozzles for discharging a fine fog of water to absorb heat by evaporation, the improvement comprising: an electronic control module to control the flow rate of the water from the reservoir; a compressor to provide pressurized air to the reservoir; a valve disposed between the nozzles and the reservoir, said valve being responsive to control signals from the control module to vary the flow of water between said reservoir and said nozzles; and means to activate and adjust said delivery system between continuous, intermittent and pulsing operation wherein said module adjusts the operation of said compressor and said solenoid valve accordingly.
Claim 5
Dependent Claim 139 words
An evaporative cooling delivery system for use in the cabin of an open air vehicle, the delivery system having operatively connected a power supply, refillable water reservoir, a supply of water in the reservoir, and a plurality of nozzles for discharging a fine fog of water to absorb heat by evaporation, the improvement comprising: an electronic control module to control the flow rate of the water from the reservoir; a compressor to provide pressurized air to the reservoir; a valve disposed between the nozzles and the reservoir, said valve being responsive to control signals from the control module to vary the flow of water between said reservoir and said nozzles; and means to activate and adjust said delivery system between continuous, intermittent and pulsing operation wherein said module adjusts the operation of said compressor and said solenoid valve accordingly.
Claim 6
Dependent Claim 20 words
The evaporative cooling delivery system of claim 3 further comprising a check valve disposed between said compressor and said reservoir.
