Problems solved by technology

Therefore, many large air supply units have to be arranged in the air-conditioned space, and there is a problem that it is difficult to secure installation places for the air supply units.
Moreover, in the case where pollutants are generated from a part accompanied by heat generation or its vicinity, since the pollutants are dischar

Example Embodiment

[0085] Example

[0086] As shown in Fig. 19, the air supply unit is arranged on a floor of 15m×16m in plan view, and a partition (non-air-conditioned space) of 7.1m×7.2m is formed on a part of the inside. The floor area is 190m. 2 In an air-conditioned space (machine room) 10 with a ceiling height of 10m, a nozzle with a diameter of 500mm that blows air horizontally was installed at a height of 4m, and air conditioning by these air supply units and nozzles was performed. The air supply unit of the embodiment of the present invention and the conventional air supply unit of Comparative Example 1 are compared. The air supply unit of the present invention has an air supply port formed in the front of a width of 0.6 m and a height of 2.1 m, and is installed on each air supply port. The air supply unit of the structure where the guide fins are provided with a rotating component to the low temperature air SA is surrounded by a cylinder. The air supply unit of Comparative Example 1 has a ...

Abstract

In this exchange ventilation system 1 where the low-temperature air SA is supplied into an air conditioning space, and the heated air raised by being heated in the air conditioning space is exhausted EA to perform the ventilation, a plurality of guide fins 30 are mounted on an air supply hole for the low temperature air SA to give the swirling component to the low temperature air SA blown out into the air conditioning space, the plurality of guide fins are radially mounted around a central axis of the air supply hole, and respectively inclined to a plane orthogonal to the central axis of the air supply hole at the same angle, and a cylindrical inner wall face applying the central axis of the air supply hole as its central axis, is formed around the plurality of guide fins.

Description

technical field [0001] The invention relates to a ventilation system. Background technique [0002] Ventilation systems are known as air conditioning systems capable of reducing the concentration of pollutants in living areas in conditioned spaces and maintaining comfort even at high cooling supply air temperatures. In this ventilation system, air with a temperature slightly lower than room temperature is supplied at a slow speed to the living area formed in the lower part of the air-conditioned space, and the air is heated by heat generating bodies (such as people) etc. present in the living area. An updraft is generated, thereby transporting pollutants such as dust and gas generated in the air-conditioned space to the upper side of the air-conditioned space. According to the reference (Yuan, X., O, Chen and L.R.Gllcksman: Performance Evaluation and DesignGuideline for Displacement Ventilation, ASHRAE Trans., 105(1999), pp.308), regarding the air supply velocity in this ve...
