An air conditioning apparatus includes at least one vessel for containing frozen material, at least one duct in thermal communication with the at least one vessel, at least one fan for propelling air through the at least one duct, and at least one battery for powering the at least one fan. The at least one vessel and the at least one duct are preferably in thermal communication with each other through a common wall. Heat fins are preferably provided on the common wall for maximizing the thermal communication. Insulating material preferably covers the at least one vessel and the at least one duct. The at least one duct may have an air entrance port and an air exit port and the at least one fan may include a first electric fan at the air entrance port and a second electric fan at the air exit port. A method of cooling air includes the steps of placing frozen material inside at least one container having an exterior surface, and propelling air into thermal communication with the at least one container over the exterior surface of the at least one container so that heat is transferred from the air into the at least one container.
