Heat Pumps

Heat pumps represent a thermodynamically elegant solution to space conditioning by transferring thermal energy from a low-temperature reservoir to a high-temperature zone. Unlike furnaces that generate heat through combustion, heat pumps exploit the reversible vapor compression refrigeration cycle to move heat against its natural gradient, achieving heating efficiencies exceeding 100% when measured by traditional metrics.

Fundamental Operating Principle

The heat pump operates on the Carnot cycle’s practical implementation—the vapor compression cycle. During heating mode, the system extracts heat from an outdoor source (air, ground, or water) and delivers it indoors at elevated temperature. The process reverses the conventional refrigeration cycle’s purpose while maintaining identical thermodynamic mechanisms.
