Heat pump water heaters
Heat pump water heaters operate by transferring heat from the surrounding air to the water, diverging from traditional water heaters that rely on consuming electrical or fuel energy to generate heat.
In this process, a liquid refrigerant undergoes evaporation to become a gas within the evaporator, facilitated by a fan. Subsequently, it undergoes compression within the compressor, transforming into a hot gas. The hot gas then traverses through a heat exchanger, where its thermal energy is transferred to the water flowing from a storage tank. After transferring its heat, the refrigerant cools down, returning to its liquid state, and re-enters the evaporator to repeat the cycle anew. Consequently, heat extracted from the air is efficiently transferred to the water, sustaining the heating process until the desired temperature is achieved.
