HVAC System

Abstract

An HVAC system is provided that is modular. The system may contain condenser modules, heat exchanger modules, and heat pump modules that can replace each other. Heat generated from the condenser modules may be recycled by the heat exchanger modules and/or the heat pump modules, using the air flowing in the system as the medium.
