Abstract

<P>PROBLEM TO BE SOLVED: To reduce heat radiation from an outdoor unit of an air conditioner to save energy and to realize environmental harmony. <P>SOLUTION: The water is intermittently dropped to a part of a heat exchanging portion of the outdoor unit of the air conditioner, so that a hot air temperature of the outdoor unit approaches the outside air temperature, and energy can be saved. This method by intermittently dropping the very small quantity of water has the effect of vaporization heat, and prevents waste consumption of water. The intermittent dropping is performed manually by a valve, or automatically fuzzy-controlled by a microcomputer by measuring the outside air temperature and a discharge temperature. As the water, hot water remaining in a bathtub, accumulated rainwater and the like are used. In a case of an automobile, the water is intermittently dropped to a part of a radiator, so that a temperature of hot air discharged from the radiator approaches the outside air temperature. The system is operated when the radiator is in a heating state. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to an air conditioner outdoor unit water intermittent dripping method in an air conditioner in which energy saving of electric power and hot air temperature of an outdoor unit are brought close to the outside air temperature.

  In the past, heat exchangers for air conditioner outdoor units used a fan to dissipate the heat of vaporization caused by CFCs in summer. When the temperature was high, hot air came out of the outdoor unit and was listed as one of the heat island factors in the city. When an outdoor unit is installed on the road side, hot air hits the passerby directly. In addition, power consumption in summer has become a factor, and power companies have to invest a large amount of equipment for power consumption in summer, so idle facilities have increased in spring and autumn. Was inevitable.

Although it is a well-known technique to cool by vaporization heat when a small amount of water is dropped on the heat exchange part of the outdoor unit, it has reached today without being utilized.

  The patent publication and heat exchange type air conditioner described above are not actually implemented. In this publicity, water is sprayed and dripped with a pump, and there is a figure that fountains from three places. The amount of water required is 1 liter per minute, 60 liters per hour and 300 liters for 5 hours. If it is used at home in the summer drought season, it is expected that it will soon run out of water. In addition, if a large amount of water is sprayed, the effect of heat of vaporization cannot be expected, and the effect is reduced by half because of water cooling. This is presumed to be the reason why the heat exchange type air conditioner is not utilized. However, the temperature of the air discharged from the outdoor unit of the air conditioner becomes higher than the outside air temperature in summer, and when a large number of air conditioners are operated, the outside air temperature further rises to a heat island state. In addition, the power requirement in summer will increase, and it will be necessary to increase capital investment by electric power companies.

  The present invention is intended to solve the problems of such a conventional configuration, and reduces heat dissipation from the outdoor unit of the air conditioner, saves energy, and realizes environmental harmony. It is the purpose.

  In the present invention, water is intermittently dropped into the heat exchange part of the air conditioner outdoor unit, and the temperature of the air to be discharged is reduced by dripping a small amount of water to about two places above the heat exchange part without using a pump. Move closer to the temperature. Environmental destruction such as heat islands is reduced, and by increasing heat exchange efficiency, summer power requirements are reduced and capital investment of electric power companies is reduced. The air conditioner outdoor unit has a structure in which a small amount of water is dropped intermittently by a drop or the like without using a pump in the heat exchange part of the outdoor unit.

  As described above, the air conditioner outdoor unit water intermittent dripping method of FIG. 1 according to the present invention drops a small amount of water on the heat exchange part of the outdoor unit to bring the temperature of heat dissipation closer to the outside temperature and also consumes power. Is to alleviate.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
In the figure, reference numeral 1 denotes an air conditioner outdoor unit having a heat exchanging unit 3 therein. A water dripping pipe 4 is attached to the heat exchanging section and connected to the water tank 2. This piping is installed in about two places on the heat exchange unit 3 by making holes in the upper lid of the outdoor unit. For intermittent dripping of water, the valve may be adjusted manually, or the air temperature entering and exiting the heat exchange unit may be measured, and automatic control by fuzzy etc. may be performed by a microcomputer. The water tank holds rainwater and the remaining hot water from the bath, but it is put in with a pump or a bucket and then added automatically in a special container. The dedicated container has a single water inlet / outlet, a lid with a tube, and a dedicated container placed downward in the water tank, making automatic water injection easy. . When multiple dedicated containers are installed, they can be made small and light and easy to carry. If the water is dripped with a pump, the water tends to be excessive, and it becomes water-cooled rather than the heat of vaporization of water, and the effect is reduced in summer when the water temperature is high. If even a part of the heat exchange part is intermittently dropped in a small amount, the heat exchange part is cooled as a whole due to the effect of heat of vaporization, and the effect is sufficient.

  In the case of automobiles and trains, the same effect can be obtained if a minute amount of water is intermittently dropped onto the heat exchanging section, which is a radiator, in the same manner as the air conditioner.

  The operation of the above configuration will be described below. Make a hole in the top cover of the air conditioner outdoor unit, or remove the top cover and install the water dripping device. When water is intermittently dropped onto the heat exchange unit, the water evaporates due to the heat of the heat exchange unit or the wind flow of the fan. With the heat of vaporization, the heat exchange unit approaches the outside air temperature. If water is applied to a part of the heat exchanging part, the heat exchanging part is connected by metal, so the whole approaches the same temperature, and the effect is sufficient. At that time, the structure should be such that rainwater does not enter the electronic components. Water is placed in a tank, and water is poured from the remaining bath water or rainwater storage tank by a pump or by hand. It is also possible to measure the discharge temperature and the outside air temperature of the air conditioner outdoor unit and automatically control the amount of intermittently dropped water by fuzzing with a microcomputer.

The figure which shows one Example of the water intermittent dripping system of the air conditioner outdoor unit of this invention.

Claims (2)

          Air conditioning equipment includes air conditioners, fans, and coolers. Among them, air conditioners are widely used. Air conditioners are said to cause hot air to flow out of the room when the temperature is high, which consumes electric power and destroys the environment. As countermeasures, water is intermittently dropped on the heat exchange part of the outdoor unit of the air conditioner to bring the hot air temperature of the outdoor unit closer to the outside air temperature and to save energy. When spraying and dripping a large amount of water in a fountain state, the effect of heat of vaporization is faint, and the method of intermittently dripping a small amount of water has a greater effect of heat of vaporization. In addition, waste of water can be prevented. In addition, if water is used, such as remaining bath water or rainwater storage water, water shortage can be dealt with. In summer, heat generated by automobiles becomes large due to the use of air conditioners, which is a cause of heat island in cities. As a countermeasure, water is intermittently dropped onto a radiator portion which is a heat exchange section, and the hot air temperature discharged from the radiator by the heat of vaporization is brought close to the outside air temperature. If the radiator is operated when it is in a heated state, it can be handled.
