Description

The present invention relates to an air conditioner utilizing natural energy.

As a conventional air-conditioning device utilizing natural energy, there is one disclosed in Japanese Patent Application Laid-Open No. 2016-23850 (Patent Document 1). The document discloses an apparatus for obtaining cold air by flowing water through a panel-shaped porous object, passing air through the panel with a fan, and cooling with the heat of vaporization.

Japanese Unexamined Patent Publication No. 2016-23850

However, since summer in Japan is hot and humid, the above-mentioned conventional air-conditioning system that utilizes natural energy only drops about 3 degrees from the temperature on high humidity days. Therefore, for example, 35 degrees is lowered only to about 32 degrees, and it is damp with humidity. In addition, since the above-mentioned conventional air-conditioning system utilizing natural energy is evaporative cooling, the wind does not cool when it is damp and the humidity rises in summer in Japan where the humidity is high. As described above, there is a problem that it is difficult to control the temperature and humidity by using natural energy.

Therefore, the present invention has been made in view of such a problem, and an object of the present invention is to provide a natural energy utilization heating / cooling device capable of controlling temperature and humidity by using natural energy. ..

In order to solve the above problems, according to the present invention, the present invention comprises a fan for creating an air flow and a plurality of heat exchangers arranged along the direction of the air flow, and at least one of the heat exchangers is provided. A heating / cooling device utilizing natural energy, which has a heat exchange section in which ground water is dropped by flowing water, and is characterized in that the ground water is vaporized and the temperature of the air changes by passing air through the heat exchange section. Provided.

According to such a configuration, at least one heat exchanger is assumed to have a heat exchange unit in which groundwater is dropped by flowing water, and is brought into gas-liquid contact with the groundwater dropped by flowing water in the heat exchange unit. Therefore, the temperature of the air can be changed by vaporizing the groundwater. Since the temperature of groundwater is almost constant at about 17 degrees Celsius throughout the year, the temperature of the air decreases due to the vaporization of the groundwater in the summer when the temperature is high, and the temperature of the air rises due to the vaporization of the groundwater in the winter when the temperature is low. Therefore, the temperature and humidity can be controlled by using natural energy.

Further, since the heat exchanger has a structure in which groundwater is poured on the surface, a simple structure is sufficient and the cost can be suppressed. Moreover, since the heat exchanger is a flow of groundwater, fresh groundwater can always be used.

As described above, the present invention has an excellent effect because it can be used by flowing abundant groundwater. In particular, it has high utility value as an air conditioner for industrial use.

The present invention has various applications. For example, the heat exchange section may be made of a non-water-absorbing material, and groundwater may flow on the surface of the heat exchange section. Since the heat exchange unit is not made of a conventional material that absorbs water, it is possible to prevent the growth of various germs.

Further, the heat exchange unit is made of a water-absorbing material, and the groundwater may flow in excess of the amount of water that can be retained by the heat exchange unit. Since the heat exchange unit can always supply fresh groundwater, the heat exchange unit can maintain an almost constant temperature throughout the year.

Further, at least one heat exchanger may have a non-contact heat exchange unit in which water flows and exchanges heat without directly contacting air. In the non-contact heat exchange section, air and water do not come into direct contact with each other, and only heat exchange is performed by contact between air and the surface of the non-contact heat exchange section, and vaporization is not performed. Therefore, only the temperature can be changed without increasing the humidity.

Further, in the non-contact heat exchange unit, groundwater is circulated inside, and the air passing through the surface may be heat-exchanged with the groundwater flowing inside to lower the temperature. With such a configuration, the air comes into contact with the surface of the non-contact heat exchange portion, only heat exchange occurs, the temperature is lowered, and dehumidification is also performed. Therefore, it is possible to obtain a wind having a reduced temperature and humidity.

Further, in the non-contact heat exchange unit, pressurized air may be mixed with the water flowing inside by a static mixer, and the pressure may be reduced by a throttle nozzle at the inlet to lower the injection temperature. With this configuration, the temperature blown into the non-contact heat exchange section can be lowered, so that the water used for the non-contact heat exchange section can be tap water as well as groundwater, and the degree of freedom of the water used can be increased. Increase.

Further, in the non-contact heat exchange unit, hot water having a temperature higher than that of air is circulated inside, and the air passing through the surface may be heat-exchanged with the hot water flowing inside to raise the temperature. With such a configuration, the air comes into contact with the surface of the non-contact heat exchange portion, only heat exchange occurs, and the temperature rises. Therefore, it is possible to obtain a wind whose temperature has risen. Further, although there is a factory that drains a large amount of hot water of about 60 degrees, it is possible to reduce the cost by using such discharged hot water as the hot water distributed inside the non-contact heat exchange unit.

Further, the non-contact heat exchange unit may raise the temperature by depressurizing the pressurized steam with a throttle nozzle and blowing it into the inside. According to such a configuration, the temperature of the water supplied to the non-contact heat exchange unit can be raised, so that it can be used for heating.

In addition, the non-contact heat exchange unit mixes two fluids, air and water heated to 100 degrees or higher with an in-line mixer, depressurizes with a throttle nozzle, and blows into the inside to condense water vapor and generate heat. The production temperature may be increased. According to this configuration, a foehn phenomenon occurs in which water vapor condenses to generate heat, so that the temperature of water supplied to the non-contact heat exchange section can be efficiently raised.

Further, the fan may be arranged at the upstream end of the air so as to blow air to the plurality of heat exchangers. According to this configuration, since air is blown from the upstream side by a fan, convection of air occurs and the temperature can be effectively controlled.

Further, the fan may be arranged at the downstream end of the air so as to suck air from the plurality of heat exchangers. According to such a configuration, since the air is sucked by the fan from the downstream side, the diffusion of the air is suppressed and the air passes through the heat exchanger efficiently, so that the temperature can be effectively controlled.

According to the natural energy utilization air-conditioning device of the present invention, it is possible to control the temperature and humidity by using natural energy. Other effects of the present invention will also be described in the embodiments for carrying out the invention described later.

Be prepared. Hereinafter, when the two first heat exchangers 110-1 and 110-2 are not distinguished, they will be described as the first heat exchanger 110. The first heat exchanger 110 has a heat exchange unit 112 made of a non-water-absorbing material, and the groundwater is vaporized by allowing air to pass through while dripping groundwater on the surface of the heat exchange unit 112, and the temperature of the air. Is configured to change.

(1st heat exchanger 110)
The first heat exchanger 110 is arranged on the intake side of the air to cool the air. As shown in FIG. 2, the first heat exchanger 110 has a first heat exchanger 112 made of a non-water-absorbing material. The first heat exchange section 112 is formed in a porous shape by arranging a plurality of wavy stainless steel elongated thin plates 112a in the left-right direction at intervals.

A groundwater supply unit 114 for supplying groundwater is provided above the first heat exchange unit 112. The groundwater supplied to the first heat exchanger 112 is dropped from the upper part onto the thin plate 112a, travels through the thin plate 112a, and is drained from below the first heat exchanger 110. The groundwater is supplied by flowing through the first heat exchanger 110. The temperature of groundwater is about 17 degrees, which is almost constant throughout the year.

The first heat exchanger 110 cools the air by contacting the groundwater dropped on the first heat exchange unit 112 and the air passing between the thin plate 112a of the first heat exchange unit 112. If the temperature difference between groundwater and air is large, there is a slight dehumidifying effect due to dew condensation.

The two first heat exchangers 110-1 and 110-2 are arranged via the fan 120. The first heat exchanger 110-1 is arranged on the upstream side of the air, and the first heat exchanger 110-2 is arranged on the downstream side.

Next, the operation of the natural energy utilization air-conditioning device 100 will be described with reference to FIG. FIG. 4 is a diagram showing the operation of the natural energy utilization air-conditioning device 100 of the first embodiment.

As shown in FIG. 4, groundwater is dropped onto the first heat exchangers 110-1 and 110-2 by flowing water. The air sucked by the fan 120 comes into gas-liquid contact with groundwater and is cooled as it passes through the first heat exchanger 110-1. For example, if the air temperature before passing through the first heat exchanger 110-1 is 30 degrees, the temperature drops to 21 degrees after passing through the first heat exchanger 110-1. If the temperature difference between groundwater and air is large, there is also a slight dehumidifying effect due to condensation.

The cooled air comes into gas-liquid contact with groundwater and is cooled as it passes through the first heat exchanger 110-2. For example, if the cooling air before passing through the first heat exchanger 110-2 is 21 degrees, the temperature further drops after passing through the first heat exchanger 110-2. In addition, dehumidification is performed because vaporization does not occur.

Therefore, the temperature and humidity can be controlled by using natural energy.

Further, since the first heat exchanger 110 and the second heat exchanger 130 are flushed with groundwater, fresh groundwater is always used, so that the propagation of various germs can be prevented.

Further, since the first heat exchangers 110-1 and 110-2 have a structure in which groundwater is poured on the surface thereof, a simple structure is sufficient and the cost can be suppressed.

Further, when the air whose temperature has been lowered by the first heat exchanger 110-1 on the upstream side of the air is further poured onto the surface of the first heat exchanger 110-2 on the downstream side of the air and brought into gas-liquid contact with the ground water dropped by flowing. , Only heat exchange occurs without vaporization. Therefore, it is possible to obtain a wind having a reduced temperature and humidity.

Further, since the first heat exchange unit 112 is made of a metal made of a non-water-absorbing material, groundwater is absorbed and the temperature does not rise due to the outside air. Therefore, since the temperature of the groundwater flowing through the first heat exchange unit 112 does not rise, the air can be efficiently cooled.

In the present embodiment, the first heat exchange unit 112 is made of a non-water-absorbing material, but the first heat exchange unit may be made of a water-absorbing material. The groundwater flowing to the first heat exchange section may be allowed to flow in excess of the amount of water that can be retained by the first heat exchange section. In this way, since the first heat exchange unit can always supply fresh groundwater, the first heat exchange unit can maintain a substantially constant temperature throughout the year.

Further, in the present embodiment, the first heat exchanger 110-1, the fan 120, and the first heat exchanger 110-2 are arranged in this order from the upstream side of the air flow, but the fan 120 is the first heat exchanger 110.
