|1. (WO2018122083) A HEAT PUMP AND A PROCESS FOR PRODUCING A HEATED FIRST MEDIUM AND A COOLED SECOND MEDIUM|
|Applicants:||HSL ENERGY HOLDING APS
|Title:||A HEAT PUMP AND A PROCESS FOR PRODUCING A HEATED FIRST MEDIUM AND A COOLED SECOND MEDIUM|
Disclosed is a heat pump comprising a combustion engine, an expander circuit (200) and a compressor circuit (300). The expander circuit comprises a boiler (201) for producing a steam, an expander for superheating the steam (210), a first expander (220) for expanding the steam and transferring mechanical energy to a shaft (223), an expander heat exchanger (215) for heating the steam before it enters a second expander (225), a condenser (230) for condensing the expanded steam and a pump (233) for returning the condensate to a boiler. The compressor circuit (300) comprises an evaporator (310) for evaporating water to steam, a compressor (320) for compressing the steam before it is entered into the expander heat exchanger (215) for cooling, a condenser (330) for production of a condensate and a valve (340) for reducing the pressure of the condensate before it is delivered to the evaporator (310). The heat pump produces a first heated medium (500) in the condensers for e.g. district heating and a second cooled medium (400) in the evaporator, which may be discarded to the environment or used e.g. for refrigeration or air conditioning.
