Abstract

This is a collection of devices that is used to augment the existing components of an installed air conditioning or refrigeration system to reduce its energy usage. Large portion of the energy usage are increasingly getting expensive, installation of the upgrade on existing air condition and refrigeration units which are a major user of electric energy has immediate impact on the national economic problem since the installed base on these equipments are about 2.5 to 3.5 times the market for new equipment. It has the added benefit of providing positive net saving for the user for the remaining statistical life of the equipment. It would generate a large number of jobs in time with the prevailing economic situation. It is a simple process to install and can be provided as a kit that can be installed by HVAC technicians.
