Abstract
A new and improved heat powered heat pump system and method of making same is provided. More particularly, the present invention relates to a heat powered heat pump system which uses standard commonly available refrigerant fluids, supplements pressurizing the refrigerant fluid by use of an external available heat source, enables selective switching between heating or cooling modes, and utilizes a thermal four-chambered compressor having a double piston head that is partially powered by an external heat source. Since the heat powered heat pump system may be made in various sizes and configurations, it may be utilized to cool and heat the interior of vehicles using waste engine heat and an initializing battery powered heating element to provide for immediate heating and cooling. The heat powered heat pump system attains better efficiency than current systems employed for the same purpose because of its capability to use a heat source such as a solar collector, waste heat from a generator, vehicle engine or power plant, various types of fuel cells, and a gas-fired or electrical heating element to power the four-chambered thermal compressor.
