AIR COOLED VENDING CART

Perishable vegetables need low temperature and high relative humidity for longer storage, especially during summer months. Therefore, there is a need to design and develop a mobile vending cart that has a low power consuming cooling component and high relative humidity as well as a moisture control mechanism or self-operated panel with a display. Among various methods, evaporative cooling is an environmentally friendly air-cooling system where water and air are the working fluids, hence used in this cart. The unit is inexpensive, energy efficient and environmentally friendly.
