Background

Golf Cart Misters Incorporated, led by CEO Ari Petersen, is a small company that designs, manufactures, and installs misting systems on golf carts. By creating and spraying fine mists of water through small nozzles and a fan, the misting system can effectively cool patrons while they drive to the next course, tallying their score, or just taking a break. These misting systems enable cooling of customers during the hottest months of the year, encouraging golfers who were originally hesitant to golf due to the intense heat. In addition to golf carts, other open air vehicles such as boats, dune buggies, and tractors are also ideal targets for these misting systems to be installed on. The main objective of this project is to redesign and build on the original misting systems, seen above, that are currently installed at a golf course in Arizona.

Existing Golf Cart Misters Misting Systems

Objectives

While redesigning the mister system, the following requirements were considered:

• The system must be suitable for multiple models of golf carts, such as the Club Car and EZ-GO models, and in so doing the system should be able to be mounted on varied dashboards and roof support beams of said carts. This is accounting for the possibility of carts having windshields and differing angles of support beams.

• The system should be self-contained on the lower front of the cart for easy maintenance and aesthetics. Sturdy and easily accessible toggle switches will be the main interface that the customers will have to turn on the fans and misters.

• The system will run off of each cart’s combined battery voltage of 48 volts, to be converted into 12 volts for use by the system. These 12 volts will power the two fans and the pump that feeds water to the accumulator to be pressurized.

• The mister system should have enough water to be able to produce a fine mist, as to not drench the client, for about 3 to 4 hours, or the length of an average game of golf, before the water tank must be refilled.

• The water tanks should allow air to escape while refilling but prevent any unwanted fluids from entering when not being refilled by means of a one-way hose insert. Any run-off water must be redirected away from the cart equipment and customers and drained to the ground.

• Additionally, the cost of production for the misting system should be around $150, effectively cutting current costs by 50%. This can ultimately be done through the reduction of the need of extensive manufacturing and assemble costs, in addition to the cost of components used in the system. 

• Time permitting, a card reader will also be implemented to allow for customers to pay for the misting system themselves.
