Abstract: A second condenser includes a condensation promoting portion that promotes a condensation action on a refrigerant by reduction of the sectional area of a refrigerant path. The condensation promoting portion includes a step-forming wall between the sectional area reduced portion and a refrigerant path portion in the upstream thereof A vortex/turbulent flow generator is provided as necessary in the upstream and downstream of the sectional area reduced portion of the refrigerant path. The air conditioner includes a first condenser and a second condenser that are coupled in a crossflow manner so that an object for heat exchange, that is, a coolant passes first through the second condenser including the condensation promoting portion and then through the first condenser.

Abstract: A load value of an external load is detected by a load value detector. When a heat quantity recovered by a heat load from a heat engine or a fuel cell is smaller than a predetermined value, a CPU calculates electric power to be consumed by an electric heater based on a relation between a heat value of heat load relative to a load value of a generator or fuel cell and a heat quantity recovered from generator or fuel cell stored in a memory of a power setting unit, so that the sum of heat quantities recovered from waste heat of heat engine or fuel cell and from generated heat of electric heater by heat load is the predetermined value, thereby controlling electric heater according to the result.

Abstract: A three-dimensional storage apparatus consists of a stacker truck movable along an aisle formed between opposing sets of cantilever arms at different levels projecting from a plurality of pillars disposed on each side of the aisle. The stacker truck has a vertically movable loader upon which transfer forks are pivotally mounted for displacement between an article support position and a stowed position. With the transfer forks in the stowed position the width of the stacker truck is significantly reduced thus allowing a reduction in aisle width and an increase in storage efficiency.
