Description

  The present invention relates to a cooling assistance device and a cooling assistance method that improve heat dissipation characteristics of a heat exchanger of an outdoor unit for a cooling device installed outdoors and can save labor of the entire cooling device.

  The air conditioner has an outdoor unit outdoors, and the refrigerant dissipates heat through the heat exchanger of the outdoor unit and condenses. Therefore, the heat dissipation characteristics of the heat exchanger greatly contribute to the operating efficiency of the entire air conditioner. Affect.

  Especially in urban office buildings, etc., many outdoor units are installed in a confined roof space in a dense state, and they are exposed to the sun so that the temperatures of the heat exchangers of each outdoor unit and the surroundings of the outdoor units Since the air temperature is increased, there has been a concern about a decrease in heat dissipation characteristics of the heat exchanger.

  Therefore, conventionally, a cooling assist device that cools the heat exchanger of the outdoor unit is used in order to improve the heat radiation characteristics of the heat exchanger of the outdoor unit (see, for example, Patent Document 1).

  This cooling auxiliary device sprinkles water toward the heat exchanger and cools the heat exchanger itself, thereby improving the heat radiation characteristics and improving the operation efficiency of the entire cooling device.

  However, in this type of cooling assistance device, since tap water is mainly sprinkled directly toward the heat exchanger, scale (scale) composed of components such as calcium, magnesium, and silica contained in tap water is used in the heat exchanger. There is a possibility that the performance of the heat exchanger may be impaired due to adhesion, and there is a possibility that corrosion of the heat exchanger may be caused by a chlorine component or the like contained in tap water.

  On the other hand, in this type of cooling assist device, a technique for reducing scale adhesion and corrosion by strictly controlling the amount of water spray and the timing of water spray (for example, see Patent Document 2) has been proposed. In such a conventional technique, the apparatus becomes complicated, the apparatus becomes expensive, and the problem of scale adhesion and corrosion has not been fundamentally improved.

  Therefore, this type of cooling assistance device includes reverse osmosis membrane treated water generating means for generating reverse osmosis membrane treated water (hereinafter referred to as RO water) by reverse osmosis membrane treatment from water supplied from a water supply source. In addition, RO water that has been subjected to reverse osmosis membrane treatment instead of tap water has been developed to be sprayed toward a heat exchanger (see, for example, Patent Document 3).

  Therefore, in this cooling auxiliary device using RO water, a large amount of reverse osmosis membrane treated water generating means is required to generate a large amount of RO water, and the introduction cost and operating cost of the device increase accordingly. there were.

  In addition, in the cooling auxiliary device that directly sprays water to this type of heat exchanger and cools the heat exchanger, the amount of sprayed water is large, so the sprayed RO water remains without being evaporated or dissipated, and is inefficient. In addition, there is a possibility that surplus RO water may submerge the floor surface around the outdoor unit and the inside of the outdoor unit. Therefore, conventionally, a means for treating surplus RO water is required, and the introduction cost and operation of the apparatus are correspondingly required. There was a problem that the cost increased.

  Although the usage mode of each spray nozzle 5,5 ... is not specifically limited, for example, as shown in FIG. 4, it is a width direction on the outer surface of the outdoor unit 1 and the surface where the heat exchangers 12, 12 are exposed.

  In the cooling assistance method using the cooling assistance device 2 configured as described above, the reverse osmosis membrane treated water is generated from the water supplied from the water supply source 3 by using the reverse osmosis membrane treated water generation means 4. Then, the reverse osmosis membrane treated water is sprayed to the air around the outdoor unit 1 with a desired particle size, whereby the air around the outdoor unit 1 is passed through the heat exchangers 12 and 12 of the outdoor unit 1 for the cooling device. When the refrigerant is condensed by exchanging heat with, the air around the heat exchangers 12 and 12 can be cooled to enhance the heat dissipation of the heat exchangers 12 and 12.

  That is, in the method of the present invention, the RO water mist is vaporized by spraying RO water in a fine mist form toward the air around the outdoor unit 1 from each spray nozzle 5, 5. By taking the heat of vaporization from the air, the temperature of the air around the outdoor unit 1 decreases, and the outdoor unit 1 takes in the reduced ambient air and exchanges heat with the heat exchangers 12 and 12 to the outside. Since the exhaust is performed, the heat dissipation characteristics of the heat exchangers 12 and 12 are improved.

The sprayed RO water is vaporized and dissipated, so it does not adhere directly to the heat exchangers 12 and 12 and can prevent scale adhesion and corrosion. Since it does not fall into the machine 1 and be immersed in water, no means for surplus water treatment is required.

  Accordingly, the treatment capacities of the reverse osmosis membrane treated water generating means 4 and treated water supply means 6 may be small, and accordingly, the apparatus can be reduced in size and price, and the operating cost (running cost) can be reduced. Can do.

  Moreover, since RO water is used for spraying, impurities contained in the air around the outdoor unit 1 to be taken in can be suppressed, and deposits and corrosion on the heat exchangers 12 and 12 can be prevented. It is possible to prevent clogging caused by impurities in the spray nozzles 5, 5..., Which is the diameter, and the life is long and management is easy.

  Furthermore, by spraying RO water intermittently at a desired time interval, the operation time of the apparatus can be shortened and the amount of RO water to be sprayed can be reduced. The spray interval of the RO water is not particularly limited for both the spraying time and the stopping time, but it is preferable to stop for 15 to 30 seconds after spraying for about 5 seconds. Adjust the temperature, humidity and other conditions. Moreover, you may make it spray continuously.

  Next, the cooling assistance effect by this invention apparatus and this invention method is demonstrated.

  Here, ventilation means such as a fan 13 is disposed on the upper surface portion, and heat exchangers 12 and 12 are disposed on the outer surface of the housing 11, respectively, and ambient air is taken in from the outer surface of the outdoor unit 1, and heat exchange is performed from the upper surface. Using the outdoor unit 1 that is exhausted, the electricity consumption reduction rate of the entire cooling device is measured for the examples in which the installation positions and angles of the spray nozzles 5, 5. The cooling assistance effect was verified based on the rate.

  Further, as the spray nozzles 5, 5..., Three types of spray nozzles 5, 5... (Whose diameters are 0.15 mm, 0.3 mm, 0.5 mm, respectively) are used. The cooling assistance effect due to the difference was also verified.

  In Example 1, two spray nozzles 5, 5... Are installed at intervals in the horizontal width direction at the upper end of the outer surface of the outdoor unit 1 (FIG. 5A), sprayed for 5 seconds, and then stopped for 30 seconds. The spray interval was repeated.

  In Example 2, two spray nozzles 5, 5... Are installed at a distance of about 1/3 from the upper end of the overall height of the outdoor unit 1 (FIG. 5B) in the horizontal width direction. The spray interval was stopped for 30 seconds after spraying for 2 seconds.

  In Example 3, two spray nozzles 5, 5... Are installed at an interval of about 1/3 from the upper end of the overall height of the outdoor unit 1 (FIG. 5B) with a gap in the width direction for 5 seconds. The spraying interval was stopped for 15 seconds after spraying.

  In Example 4, two spray nozzles 5, 5... Are spaced apart in the horizontal width direction at every height of about 1/3 and about 2/3 from the upper end of the overall height of the outdoor unit 1 (FIG. 5C). The spraying interval was set to rest and sprayed for 5 seconds and then stopped for 30 seconds.

In Example 5, two spray nozzles 5, 5... Are spaced apart in the horizontal width direction at every height of about 1/3 and 2/3 from the upper end of the overall height of the outdoor unit 1 (FIG. 5C). The spraying interval was set to rest and sprayed for 5 seconds and then stopped for 15 seconds.
The results are shown below.

  Thus, it was confirmed that the amount of electricity used by the entire cooling device including the cooling assistance device 2 was reduced by using the cooling assistance device 2 and the cooling assistance method according to the present invention.

  In particular, when the stop time is shortened in the spray interval, the amount of water used is increased, but the amount of electricity used in the entire apparatus is reduced, and the running cost is reduced as a whole.

  Further, when the nozzle diameter was 0.3 mm, the efficiency of reducing the amount of electricity used was the highest. That is, the mist particle size of the sprayed RO water has a large effect on cooling assistance, and if the mist particle size is small, it is swept away by the influence of the wind. Becomes difficult to cool.

  In the above-described embodiment, the example in which the reverse osmosis membrane treated water generating means 4 and the treated water supply means 6 are separately unitized has been described. However, the reverse osmosis membrane treated water generating means 4 and the treated water supply are described. You may make it provide the means 6 integrally.
