Title: Heat engine heat pump
With the help of specialized technology, the heat engine heat pump (WKWM) can generate power, cooling and low-temperature heat (heat pump) from fluids of higher temperature (e.g., warm water, hot water), high-temperature exhaust gases and solar energy. The heat transfer medium can be liquid gas, e.g., coolant R 134a. The system unifies heat engine (WKM) and heat pump (KWM), which is achieved by joint use of the condenser, preheater, prechiller, fluid collector and sometimes an ejector. The advantage of a heat engine heat pump, rather than separate heat engine and heat pump, is its lower efficiency losses.
