WebHeat Pump. A heat pump is basically a heat engine run in the reverse direction. In other words, a heat pump is a device that is used to transfer heat energy to a thermal reservoir. They are often used to transfer thermal energy by absorbing heat from a cold space and releasing it to a warmer one. Heat pumps transfer heat from a cold body to a ... Web1 de jan. de 2024 · Some of the common faults for heat pumps have been emulated in a variable-speed water-to-water heat pump in heating mode.
