摘要： An air-conditioning apparatus includes an outdoor unit and a relay unit. The outdoor unit includes a compressor compressing and discharging refrigerant and a heat-source-side heat exchanger performing heat exchange between the refrigerant and outside air. The relay unit and the outdoor unit forms a refrigerant circuit. The outdoor unit includes first and flow switching devices each switching an associated flow passage for the refrigerant between a plurality of flow passages, according to an operation mode. An outflow pipe and an inflow pipe through which refrigerant flows from the outdoor unit to the relay unit and from the relay unit into the outdoor unit, respectively, are between the outdoor unit and the relay unit. The first flow switching device is connected to the compressor, the second flow switching device, and the outflow pipe. The second flow switching device is connected to the first flow switching device and the inflow pipe.

摘要： Provided is an electrical device. In a setting unit, a right-room temperature display unit displays a set temperature or the current temperature of a first housing room. A left-room temperature display unit displays a set temperature or the current temperature of a second housing room. A right-room temperature setting button is an operation unit for a user to switch the set temperature of the first housing room. A left-room temperature setting button is an operation unit for a user switch the set temperature of the second housing room. The set temperature difference between the first and second housing rooms is controlled to be within a prescribed value. When the set temperature of one of the first and second housing rooms is changed so that the set temperature exceeds a prescribed value, a microcomputer automatically changes the other set temperature so that the set temperature difference is within a prescribed value.

摘要： A thermal management system for a directed energy weapon includes a heat exchanger thermally coupled to the directed energy weapon. The heat exchanger has a heat exchanger inlet and a heat exchanger outlet. A storage reservoir contains a thermal material. An outlet of the storage reservoir is arranged in fluid communication with the heat exchanger to form a closed loop having a thermal management fluid circulating therethrough. The storage reservoir is thermally coupled to a secondary system. A control valve is positioned downstream from the outlet of the storage reservoir. The control valve is adjustable to control a temperature of the thermal management fluid provided to the heat exchanger.

摘要： A recovery system is provided to recover energy from heat. In an embodiment, the system includes an evaporator to receive a flow of natural gas at a first temperature and output the flow at a second, lower temperature. The evaporator may receive a flow of cooling media to cool the natural gas and output a flow of heated cooling media. The system may further include: a heat-to-mechanical energy converter coupled to the evaporator to receive the flow of heated cooling media and to output first cooled cooling media; an induction generator coupled to be driven by the heat-to-mechanical energy converter; a medium voltage drive coupled to receive power from the induction generator and to condition the power for output to an electrical distribution system; and a condenser to condense the first cooled cooling media to provide the flow of cooling media to the evaporator.
