Abstract
An expander controls the expansion and flow of refrigerant between high and low pressure within a vapor compression system. The expander drives a shaft that in turn drives a friction disk within a friction heat generator. Frictional contact between the friction disk and the plate generates heat. The friction heat generator transfers heat to the water circuit to elevate the temperature of water.
