A heat pump system, a heat management method and a vehicle are provided. The heat pump system includes an integrated heat exchanger integrated with a superconducting liquid flow passage and a refrigerant flow passage. The refrigerant flow passage is provided inside an on-board refrigerant circulation loop and is used for cooling and/or heating to adjust the temperature within a passenger compartment of a vehicle. The superconducting liquid flow passage is in communication with a motor heat dissipating conduit, for absorbing the heat generated by an on board motor and transferring the heat to the integrated heat exchanger by means of phase change heat transfer. The heat pump system can increase the energy utilization rate for the vehicle and reduce the allowable ambient temperature of the heat pump system.

Various examples include a device for increasing the heat yield of a heat source comprising: a heat sink; a heat pump with a condenser and an evaporator; and the heat source. The heat sink includes a heat sink feed and a heat sink return providing thermal coupling to the heat source with a heat exchanger. The heat source includes a heat source feed and a heat source return for thermal coupling to the heat sink with the heat exchanger. The condenser of the heat pump is thermally coupled to the heat sink feed to dissipate heat to the heat sink. The evaporator of the heat pump is thermally coupled to the heat source return downstream of the heat exchanger to absorb heat.

A system for better utilization of liquefied natural gas (LNG) on gasification of the liquid includes a gas power generation subsystem, a steam power generation subsystem, an energy storage subsystem, and a cooling subsystem. A gasification device of the gas power generation subsystem renders the LNG gaseous and collects cold energy generated during the gasification. The gas is supplied to the gas power generation device for generating electrical power and the cold energy is supplied to the steam power generation subsystem and the cold storage subsystem. Electrical power generated by the gas power generation subsystem and the steam power generation subsystem is supplied to the cooling subsystem, and the energy stored in the energy storage subsystem is also supplied to the cooling subsystem.

A refrigeration and/or heat transfer device includes a heating section and cooling section, a release member, and a one-way check valve affixed together in a continuous loop so working fluid may flow in one direction therein. The heating section absorbs heat and transfers such heat to the working fluid, thereby heating, expanding and increasing pressure upon the working fluid therein. The pressurized working fluid is released in a regulated manner from the heating section to the cooling section, thereby carrying the heat away. The released working fluid cools and transfers its heat to the surroundings within the cooling section. As released working fluid enters the cooling section, such fluid displaces already cooled working fluid, pushing such fluid through the one-way check valve back into the heating section to absorb heat. The working fluid may undergo a phase change or remain in a single phase throughout to enhance heat transfer.
