Abstract

<P>PROBLEM TO BE SOLVED: To solve problems that when water is repeatedly sprayed to circulated air, a temperature and humidity are increased, thus causing a rise of a wet-bulb temperature and an absolute temperature, and therefore, a cooling effect is deteriorated, and it is unfavorable for cooling as its purposes are dust removal and humidification, furthermore when cooling, humidifying and air-conditioning are performed by simultaneously using a dehumidifier such as an electric fluorocarbon cooler or a refrigerating machine, the cooling effect can be obtained by lowering the wet-bulb temperature with dehumidification, but when its purpose is a humidifier, the utilization of cooling is reduced as the heating and humidification of dry outside air and the like are performed in a time period when absolute humidity is low in winter when the outside air temperature is low. <P>SOLUTION: The water is sprayed in a space of low absolute humidity to produce the water of a low wet-bulb temperature, and the water is sprayed in an air washer to perform cooling. The water of a high wet-bulb temperature is produced by spraying the water in the same space, and the water is sprayed in the air washer to perform humidification. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a device having a characteristic of using a wet bulb temperature in a double air washer type air conditioning humidifying / cooling / heating machine using the wet bulb temperature.

  Air washer type equipment is divided into a central type and an individual package type. Usually, the purpose is to remove dust and humidify, and since the absolute moisture content decreases when the humidity is reduced by the air conditioner or the outside air temperature falls, temperature and humidity control is required. It is used in fields that need it.

Utilizing the characteristics of air, the difference between dry bulb temperature and wet bulb temperature, the moisture at the time of air with low relative humidity is used, and the relative humidity rises when sprayed and cooled, so it is usually used for electric Freon air conditioners and refrigeration Use machine to cool. Dehumidified moisture or moisture contained in the outside air can also be used as cooling.
No similar patent.

The air washer type air conditioner has the following problems.
(B) Repeated spraying of water on the circulating air results in warming and humidification, increasing the wet bulb temperature and absolute temperature, reducing the cooling effect.
(B) For dust removal and humidification purposes, it is not suitable for cooling.
(C) When using a dehumidifying device such as an electric refrigeration cooler or refrigerator to cool, humidify, or air-condition, it has a cooling effect by lowering the temperature of the dehumidifying wet bulb. In the case of equipment, during the winter when the outside air temperature was low, there was little use of air conditioning due to heating or humidification of dry outside air when the absolute humidity was low.

  In a space with low absolute humidity, water is sprayed to produce water with a low wet bulb temperature, and then sprayed in an air washer for cooling. Water is sprayed in the same space to make water with a high wet bulb temperature, and it is sprayed and humidified in an air washer. The present invention is a double air washer cooling / cooling machine and a heating / humidifying machine having the above-described configuration.

(B) A typical equipment is a cooling tower (cooling tower). The use of a dry bulb wet bulb temperature difference that the air-cooled and water-cooled cooling functions usually have a capacity of about 20%, and the purpose of dehumidification in a small space As described above, the wet bulb temperature of the air dehumidified by an electric air conditioner such as an air conditioner is used and sprayed with a spray nozzle, the absolute temperature rises, but cold water continues to be produced by repeated dehumidification.
(B) Global warming and the amount of chlorofluorocarbons used are only 10% compared to electric coolers.
(C) With regard to the disposal of equipment, it is easy to recycle 100% of resources, and coolers can be reused under the manufacturer recycling law.
(2) CO2 emissions are extremely reduced.
(E) Cooling is possible with energy of 1/3 to 1/4 of a power saving machine provided with an inverter or the like of an electric cooling machine using Freon.
(F) Uses the principle of nature and simple equipment, and operates with simple control. The effect is further increased by more complicated control.
(G) If global warming prevention and global air conditioners can be stopped all at once, the amount of heat generated by the motor will decrease or be used during cooling. The principle of a heat pump that cools the interior and heats the exterior. Heating effect is greater than cooling. When the capacity of this device is reduced to 1/10, it will be unimaginable how much effect will appear.
(H) In heating and humidification, spraying water suppresses an increase in the heating load that causes cooling and humidification.

  Embodiments of the present invention will be described below. Cooling operation is performed with equipment that dehumidifies and cools and heats in a small space, sprays with a nozzle to make water with a low wet bulb temperature, and cools air by spraying cold water into the air that has passed through the air-conditioned space. This is a double air washer type water cooler. A double air washer type heating humidifier that heats the equipment in the same space, creates water with a high wet bulb temperature, and sprays hot water on the air that has passed through the space to be heated and air-conditioned with a nozzle. is there. The present invention is manufactured with the structure as described above.

These are the exploded perspective views of the Example of this invention (Example 1). It is closed in a small space, and an air conditioner is attached, and the water sprayed from 3 is contacted with the air blown from 5 and the heat exchanged water is used for cooling and heating humidification. Used in No. 7, air is taken in from No. 10, and is blown by a blower of No. 9 to cool and humidify. The air 1 from which water droplets sprayed at 4 are removed is dehumidified and heated at 5.

Claims (1)

  A device that is used as a cooling and heating humidifier. In the range where the absolute moisture content is small, water using the wet bulb temperature is sprayed on the return air in the air conditioner to generate humidification cooling air, and the air is cooled down. It is a device that boosts cooling capacity and conserves electricity by dampening. In addition, air conditioners, water heaters that use water heat exchanger coils to cool, water that exceeds the wet bulb temperature of the air-conditioned space by wet bulb temperature, and humidifying spray water with high water temperature can also be made by heating. Since it can be done, the humidification ability is improved.
