Abstract
A mechanical leverage system comprising an expansive side and a compressive side, wherein the compressive side comprises a compressor which is in controlled fluid communication with a first evaporator and a first condenser, wherein the expansive side comprises an expander which is in controlled fluid communication with a second evaporator and a second condenser, wherein the second evaporator absorbs heat from a space such as an attic and drives the expander, and thus, the compressor to which the expander is connected, and wherein there is a difference between the properties of the refrigerant used in the expansive side and the compressive side, such that the difference in refrigerant properties influences the mechanical advantage ratio of the system.
