Description

  The present invention relates to a dehumidification system that performs dehumidification in an elevator shaft of an elevator apparatus, and more particularly relates to a dehumidification system suitable for an elevator apparatus for a refrigerator such as a refrigerated warehouse composed of a plurality of floors.

  Various types of air conditioning in an elevator apparatus have been conventionally proposed for an elevator cab (see, for example, Patent Documents 1 and 2).

  In addition, the elevator apparatus is provided with a machine room provided with equipment for raising and lowering the elevator cab, but this machine room is provided with a motor and an electric circuit for driving and controlling the motor, and such an electric circuit has a failure due to condensation, Since there exists a possibility of malfunctioning, the proposal which provides a dehumidifier in a machine room is also made | formed (for example, refer patent document 3).

  By the way, as described above, the air conditioning for the elevator cab and the machine room has been actively considered and proposed in the past. However, technical proposals for the air conditioning in the elevator shaft where the cab is raised and lowered are mostly made. The current situation is not.

However, the moisture in the elevator shaft can cause mold to adhere to the inner wall of the shaft, condensate on the lower floor, and rust on the equipment in the shaft. Cause.
In addition, the above-described dew condensation on the electric circuit may cause a malfunction or malfunction of the apparatus.

  Such a problem also exists in a general building elevator device, but in an elevator device of a refrigeration facility composed of a multi-storey refrigerator, the elevator device greatly affects the temperature difference between inside and outside the facility. Since the refrigeration facilities are mostly used for refrigeration of foods, hygiene problems such as the occurrence of mold due to moisture described above can never be left.

In the elevator device described above, the cool air in the front chamber (loading room, work room, etc.) for carrying in and out of the refrigerator is introduced into the elevator shaft, or the air in the elevator shaft is sent to the outside for ventilation. There have been technical proposals such as to do so, but at present, sufficient effects have not been obtained and it has not yet been put to practical use.
Japanese Patent Laid-Open No. 9-58943 (pages 1-6, FIGS. 1-12) Japanese Patent Laid-Open No. 10-231079 (pages 1 to 5, FIGS. 1 to 4) Japanese Utility Model Publication No. 63-77980 (first page, FIG. 2)

  The present invention can reliably perform dehumidification in an elevator shaft, can prevent mold from sticking to the shaft, condensate water from being accumulated, rust from being generated on the equipment, and condensation water from being attached. An object of the present invention is to provide a dehumidification system that can improve the hygienic condition, durability, and reliability.

In order to solve the above problems, a dehumidifying system according to the present invention is a dehumidifying system for an elevator apparatus for a refrigeration facility including individual refrigerators on a plurality of floors, and a base end is connected to an air outlet of the dehumidifying apparatus A blower duct having a plurality of blower openings in the longitudinal direction is provided along the moving direction of the elevator cab in the elevator shaft, one end faces the elevator shaft, and the other end is connected to the air inlet of the dehumidifier A suction duct is provided, a plurality of suction ports are provided in the longitudinal direction of the suction duct , the suction duct is provided in the elevator shaft so as to be substantially parallel to the blower duct, and the suction port and the blower port are connected to the elevator. disposed so as to alternate in the vertical direction in the shaft, and the air blowing port, disposed at a position slightly higher than the floor of the refrigerator floor, or the blower opening By keeping the dehumidified air is delivered to the low humidity meet in the elevator shaft, there as those configured to prevent dew condensation in the elevator shaft by cold air entering from the refrigerator in the elevator shaft.

  According to the present invention, the dehumidified air is efficiently supplied into the elevator shaft, and the humidity in the shaft can be kept low at all times. Therefore, hygiene problems such as generation of mold and retention of condensed water in the elevator shaft can be avoided. In addition, it is possible to prevent the malfunction and malfunction caused by the rusting on the equipment in the shaft and the dew condensation on the electric circuit, and the durability and reliability of the elevator apparatus can be improved.

Embodiments of a dehumidifying system according to the present invention will be described in detail below based on specific examples shown in the accompanying drawings.
In the present embodiment, an example of a dehumidification system in an elevator apparatus of a refrigeration facility 2 configured on a plurality of floors (fourth floor in FIG. 1) having individual refrigerators 1 and 1 on each floor will be described.

  A dehumidifying device 7 is provided in a machine room 6 provided with an elevating drive device 5 for raising and lowering a car room 4 in the elevator shaft 3, and an air duct 8 having one end connected to an air outlet 7 a of the dehumidifying device is provided. The elevator shaft 3 is suspended around the car room 4, and a plurality of air outlets 9 and 9 are provided in the air duct 8.

  Each of the air vents 9 and 9 is provided so as to correspond to one place on each floor, for example, and is disposed at a position slightly higher than the floor in the refrigerators 1 and 1 on each floor.

  A suction duct 10 having one end connected to the air inlet 7b of the dehumidifying device 7 is also suspended in the elevator shaft 3 so as to be parallel to the blower duct 8, and a plurality of suction ducts 10 are provided in the middle of the suction duct 10. Suction ports 11 and 11 are provided.

  In addition, each intake port is provided so as to correspond to each floor of the facility, and is provided so as to be paired with the blower port. The blower port and the suction port are alternately arranged in the height direction in the elevator shaft. It is provided at the position.

  As a result, the dry air sent into the elevator shaft 3 from the air blowing ports 9, 9 spreads evenly in the shaft and dehumidifies, and the air containing moisture in the shaft efficiently passes through the suction ports 11, 11. It is sucked and returned to the dehumidifying device 7, so that the dehumidification in the shaft can be reliably performed.

  In the embodiment described above, the dehumidifying device 7 is provided in the machine room 6. However, as shown in FIG. 2, the dehumidifying device 7 may be provided in another place such as the roof of a refrigeration facility.

  Further, as shown in FIG. 3, the suction duct 12 may be configured such that the lower end suction port 13 faces the upper part in the shaft 3.
