Problems solved by technology

That is, warm water, etc. cannot make the surface of the oblique honeycomb body uniformly wet, and cannot make full use of the large surface area of ​​the oblique honeycomb body, so the thermal efficiency is lower than that of the finned spiral tube cooler, which cannot be regarded as a good thermal efficiency. air cooler use

Embodiment 1

[0045] Glass non-woven fabric made of E-glass fiber and organic binder is dipped in a slurry containing alumina hydrate as a filler material and alumina gel as a binder, dried, and processed to form waves to obtain a waveform thing. The corrugated objects are laminated alternately so that the propagation direction of the wave intersects, and then heat-treated at a temperature of 500°C to form a total amount of 80% by weight of alumina and alumina gel hardened product and 20% by weight of E-glass fiber. , a diagonal honeycomb body with a porosity of 65%, a tooth height of 4.8mm and a pitch of 10mm. The oblique honeycomb body is 1000mm wide relative to the ventilation direction of the air, the height is 400mm, and the depth is 200mm. figure 1 The symbol Y) in is 60 degrees, the inclination angle relative to the air inflow and outflow direction (horizontal direction) when viewed from the front and back sides of the units arranged obliquely ( figure 1 The symbol X) in is 30 degr...

reference example 1

[0048] The cooling unit uses an oblique honeycomb body with a width of 1000mm, a height of 1200mm, and a thickness of 200mm. After including the water supply pan and drain pan, the cooling unit is configured with a width of 1000mm, a height of 1300mm, and a depth of 200mm. Arranged in 1 layer and 1 row. A total of 1 unit), except for using a case with the same shape and a size that can be installed in the cooling unit, measure the temperature and humidity of the outlet air and the pressure loss of the air cooling device in the same manner as in Example 1. . The conditions and measurement results of the cooling unit and the like are shown in Tables 1 to 3. In addition, in this example, a considerable amount of cooling water is scattered with the wind to the leeward side of the honeycomb body during operation. This is considered to be due to the same L / G as Example 1, L / G 400-200 It is larger than Example 1, and it is caused by too much cooling water in the depth direction of ...

Embodiment 3

[0054] Except that the cooling unit made in Example 1 is 1000mm in width, 1500mm in height, and 600mm in depth by 3 layers up and down, and 3 rows in the front and rear openings (the cooling unit is arranged in 3 layers and 3 rows, and the total There are 9 units.) Except, constitute the same device as embodiment 1, measurement conditions are as shown in table 3 and table 4, measure the temperature of outlet air, humidity and the pressure loss of air cooling device. In addition, since this embodiment assumes the cooling of the external air inlet for the clean room of the semiconductor factory, the content of impurity ions in the air at the inlet and the amount of impurity ions in the cooled air were also measured. removal rate. The ion concentration of impurity is obtained by analyzing the collected liquid with ion chromatogram after the impingement dust detector added with ultrapure water absorbs the air at the inlet of the collected air and the cooled air respectively. The ...

Abstract

An air cooling device includes at least one cooling unit which includes an oblique honeycomb having front, rear, upper, and lower openings and disposed so that air to be cooled is introduced into the front opening and cooled air is discharged from the rear opening, a cooling water supply means which supplies cooling water to the upper opening of the oblique honeycomb, and a water receiving section which receives discharge water discharged from the lower opening of the oblique honeycomb, and a blower means which introduces air to be cooled into the front opening of the oblique honeycomb and allows cooled air to be discharged from the rear opening of the oblique honeycomb, wherein the height of one oblique honeycomb in the cooling unit is 200 to 800 mm. The air cooling device has high thermal efficiency, a small liquid-gas ratio, and a small pressure drop, and is capable of saving space and energy.

Description

technical field [0001] The present invention relates to an air cooling device and an air cooling method for efficiently cooling high-temperature air such as in summer. More specifically, it relates to air cooling devices for office buildings, hospitals, and production plants, and air cooling methods using such devices. Background technique [0002] At present, energy used for air conditioning in office buildings and factories accounts for more than 30% of Japan's energy consumption, so reducing this part of energy consumption has become an urgent issue. At present, the circulating air of office buildings and factories and the air taken in from the outside are sent to the finned spiral tube heat exchanger with refrigerant and cooling water flowing, so that it can be cooled by passing through the finned spiral tube. However, since the finned spiral tube heat exchanger requires a large amount of cooling water relative to the amount of cooled air, that is, the liquid-gas ratio ...
