Abstract
A liquefaction heat pump system may have: a storage vessel configured to receive a liquified fuel from a piping grid network. A heat pump circuit may include sequentially at least a compression stage configured to compress the fuel, a heat pump stage configured to receive the compressed fuel from the compression stage, and to heat a coolant by removing heat from the compressed fuel by at least one heat exchanger. A pumping arrangement is configured to pump fuel from the storage vessel and/or from the heat pump circuit back to the piping grid network. A controller unit is configured for operating the liquefaction heat pump system such that fuel is liquefied and a coolant is heated by the heat pump circuit.
Claims20
A liquefaction heat pump system comprising:
- a storage vessel configured to receive a liquified fuel from a piping grid network;
- a heat pump circuit including sequentially at least
- a compression stage configured to compress the fuel,
- a heat pump stage configured to receive the compressed fuel from the compression stage, and to heat a coolant by removing heat from the compressed fuel by at least one heat exchanger;
- and
- a pumping arrangement configured to pump fuel from the storage vessel and/or from the heat pump circuit back to the piping grid network;
- and
- a controller unit configured for operating the liquefaction heat pump system such that fuel is liquefied and a coolant is heated by the heat pump circuit.
A system comprising:
- a processing unit;
- and
- a non-transitory computer-readable memory communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for:
- receiving and storing liquid ammonia from an ammonia piping grid network;
- displacing gaseous ammonia from the storing to a compression stage;
- generating heat by compressing the gaseous ammonia in the compression stage;
- heating a coolant with the compressed gaseous ammonia;
- liquefying the gaseous ammonia;
- and
- pumping the ammonia in a liquid state back into the ammonia piping grid network.
