Method and equipment for utilization of water heater waste heat recovery by built-in high temperature water source heat pump

摘要

The present invention provides a method and apparatus for utilizing low temperature waste heat. Within the scope of a water heater (HWP), there are low temperature sources that can not be used directly by a heat consuming device (HC). The method and apparatus for waste heat recovery of a water heater (HWP) preferably comprises at least one condensation type heat exchanger (HE), which collects waste heat to obtain a water source high temperature heat pump ( Low temperature heat is upgraded to high temperature heat, so that the hot water outlet of the heat pump (HP) is supplied to the boiler in the return line or supply line of the hot water heater (HWP) to match the power of the heat pump (HP) And / or adapting the power of the furnace, and / or the mass flow rate of the main heat transfer medium in the at least one open loop heating Natewak and / or at least one closed loop heating circuit within the heat distribution Neatwak By adjusting, the thermal energy balance of the generated heat is adjusted.
