Abrégé
The present invention relates to a triple-effect absorption chilling apparatus adopting a structure of an anti-parallel cycle in which an absorber and a first regenerator are connected in series, a second regenerator and a third regenerator are connected in parallel with the first regenerator, and the solution through the second regenerator and the third regenerator is returned to the absorber. Therefore, according to the present invention, it is possible to improve efficiency by acquiring a higher coefficient of performance than conventional absorption refrigerators, and to reduce energy consumption.
The present invention relates to a parking apparatus. The main components of the parking apparatus of the present invention comprise: a palette on top of which vehicles are mounted, and which installs multiple rows onto a single parking row; a lift on top of which the palette is mounted, and which moves in a vertical direction; and a transport carriage which pushes the palette mounted on the lift into the preset parking row such that the vehicle on the palette can be parked, or loads the palette in the parking row onto the lift; and a palette transport device which pulls the palette in the front row adjacent to the transport carriage, from among the palettes arranged into multiple rows in the parking row, such that the palette in the back row can move forward together with the palette in the front row, or which pushes the palette on the transport carriage into the parking row, such that the palette in the back row can move backward together with the palette on the transport carriage. According to the present invention, a bent piece of a palette is axially coupled to a bent piece of the opposite palette between rollers of the palettes such that the palette moves together with the opposite palette in a lengthwise direction, thereby arranging two or more palettes into multiple rows in a parking lot and thus enlarging a parking lot.
