Long life vehicle ventilation system

摘要

A ventilation system for a long life vehicle (LLV). A rear vent currently existing on most LLV's is secured by an adapter to provide air to a squirrel cage fan or other air pump. The cooler air is ducted to the forward passenger compartment where its glass enclosure serves to heat the confines to high temperatures during sunny days. A resistor in the ductwork serves as a generally electrically-identical configuration to an auxiliary fan currently present in most LLV's. The ductwork transmits the air pumped from the rear vent to a vent assembly having a plenum and louvers with grills. The plenum provides a small and temporary reservoir for the air flow so that it may be redirected sideways to the louvers. The louvers provide course adjustment for the airflow with finer adjustment achieved through the grills. Overall advantages include greater driver and passenger well being leading to safer operation of the vehicle as well as less thermal stress for the instruments and operating controls. The cost and expense of air conditioning including installation, maintenance, and fuel may be greatly reduced.
