Abstract: An outdoor device of an air conditioner includes a compressor, an outdoor fan, and an outdoor control board. The outdoor device includes: a control unit that controls the compressor and the outdoor fan; and a temperature detector that detects an ambient temperature of an electric component provided on the outdoor control board. The control unit, when the compressor is stopped, stops the outdoor fan and then determines whether a temperature detected by the temperature detector is equal to or higher than a threshold, and, when it is determined that the temperature detected by the temperature detector is equal to or higher than the threshold, operates the outdoor fan at a protective rotation number that is lower than a rotation number of the outdoor fan while the compressor is in operation so as to circulate air, thereby cooling the outdoor control board.

Abstract: An air conditioning system can be toggled between a heating mode, in which heat is withdrawn from a source (e.g., a geothermal source) and deposited into a conditioned space (e.g., a building), and a cooling mode, in which heat is withdrawn from the conditioned space and deposited into the source. The air conditioning system uses a combination of efficiency-enhancing technologies, including injection of superheated vapor into the system's compressor from an economizer circuit, adjustable compressor speed, the use of one or coaxial heat exchangers and the use of electronic expansion valves that are continuously adjustable from a fully closed to various open positions. A controller may be used to control the system for optimal performance in both the heating and cooling modes, such as by disabling the economizer circuit and vapor injection when the system is in the cooling mode.

Abstract: In this container refrigerator, the permissible equivalent negative-phase-sequence current of a generator to be connected is calculated in Step S3 based on its capacitance. Next, in Step S4, the power consumption of an inverter device to generate the equivalent negative-phase-sequence current is calculated. Then, in Step S6, the equivalent negative-phase-sequence current generated by the container refrigerator is calculated based on the power consumption of this inverter device. Thereafter, in Step S9, It is compared to Itg. If It>Itg is satisfied, It is restricted until It?Itg is met by lowering the output frequency of the inverter device repeatedly in multiple stages. Consequently, even if the generator connected has small capacitance, the operation may be continued at a number of rotations appropriate for that small capacitance without causing the generator to overheat or be burned out.

When moved to the second position, the movable part is relatively further away from the interior side walls to thereby permit more air flow from the first plenum chamber to the second plenum chamber.
