摘要： PURPOSE:To make it possible to do away with a drop in a sensible temperature easily when heating and reduce a sensible temperature to a satisfactory extent when cooling. CONSTITUTION:A plurality of air supply devices 31 which comprises an axial fan 39 placed between a suction side silencer 35 and a discharge side silencer 37, are laid out in a large space of a large space facility 21 while a discharge direction of the discharge side silencer 37 of the air supply device 31 is set to the flowing direction directed to the suction side silencer 37 of an adjacent air supply device 31.

摘要： PURPOSE:To compact a relief damper as an integrated structure by out-fitting a spring on an operation shaft so as to energize 2 cover body always to a discharge side opening of a hollow cylindrical body, and providing a lock mechanism to determine an operation shaft stopping position so as to hold a fully closed or fully opened condition of a discharge side opening of the cover body. CONSTITUTION:In the case of a release, a synchronous motor 42 of an operation lock mechanism 24 is rotated when a release switch is turned on, and an operation shaft 16 is moved to the release side and when a notch of a rotary plate 62 is engaged with a limit switch 66, the operation shaft 16 is held in a maximum release side position, and an air pressure releases an opening 12b. Pressure air is relieved, and a cover body 18 is displaced to the high pressure side up to becoming a preset pressure by means of a energizing spring 28, and when the opening 12b is blocked up, an slidable sleeve body 26b is engaged with a cover body closing limit switch 72, and the synchronous motor 42 is rotated by means of this signal, and when a notch of a rotary plate 64 is engaged with a limit switch 68, the operation shaft 16 is stopped/held in a maximum retreat side position, so that the opening 12b can be blocked up reliably. In such a constitution, a relief mechanism and a blocking mechanism can be formed in integral structure.

摘要： PURPOSE:To relieve high pressure side air in a short time by providing a spring to energize a release side opening of a cover body of a hollow cylindrical body in the blocking-up direction and a preset pressure regulating device having a roller body to roll while being engaged with the engaging surface of an operation shaft. CONSTITUTION:An energizing spring 20 is installed in a housing frame body 30 in a natural length or by being compressed slightly and when a pressure is changed on the high pressure side P1, a blocking-up condition is locked/held up to becoming a preset wind pressure. A release of a cover body 18 is started by energizing lock rings 54 and 55 into an inverted angle shape by means of an energizing device 56 of a preset pressure regualting device 52, and in the case where a roller body 50 gets over the first engaging surface 46a, it does not get over the engaging surface up to becoming a certain air pressure due to the resistance force, but when it gets over the engaging surface and gets over also a corner square part 47 and is once engaged with the second engaging surface 46b, the roller body 50 moves on the second engaging surface 46b to the stress side even under a slight wind pressure, and moves an operation shaft upward in a short time. In such a constitution, high pressure side air can be relieved reliably/stably.
