Abstract

<P>PROBLEM TO BE SOLVED: To save water expense while preventing contamination with water stain and rusting of equipment in an air conditioner configured to spray water to a radiator condenser of an air conditioner outdoor unit during cooling to significantly reduce power consumption. <P>SOLUTION: A spirally perforated pipe 5 is slowly rotated, and a brush-like guide cloth 6 is slightly brought into contact with the pipe 5 to solve a trouble such that water becomes difficult to flow due to formation of water drops by the surface tension, whereby a small amount of drain water can be effectively and uniformly sprayed at low cost. A rotating motor 3 is controlled in parallel to the power supply of the outdoor unit to operate only while the drain water is discharged according to detection by a water sensor 2. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

The present invention is an energy-saving system that increases the efficiency of air-conditioner cooling by a device for evenly distributing a small amount of drain water from an air-conditioner to a condenser without waste.

The method of spraying water to the air conditioner outdoor unit during cooling operation is already known and practiced, but it depends on the water quality, but it becomes dirty and reduces efficiency due to water stains, equipment rusts due to scattered water, However, it has been pointed out that the cost is not as high as expected.
Drain water is ideal because it occurs naturally and has few impurities, but it can be used free of charge.
JP2003-042476

When water is sprayed on an air conditioner outdoor unit during cooling, power consumption is reduced by about 25%, so it has been adopted in supermarkets, etc., but the water bill has become higher, white water is dirty and difficult to clean, splattered water However, if the equipment does not last long because it gets wet, the aluminum fins have rusted if it is applied without removing chlorine.
The present invention can solve most of the above drawbacks by spraying drain water from the indoor unit evenly without waste. In addition, because it can be introduced into home air conditioners at low cost, it has a large number of applications and is effective in reducing CO2.
In a place where drain water is flowing to the veranda etc. for home use, it turns green and becomes dirty with moss, but this device will evaporate all with a condenser, so such drainage can not be done It is most suitable for place.

Air conditioning drain water at the time of cooling is more frequent when the humidity and temperature are higher, so it is a small amount, but it is clean water, and in order to spray evenly to the condenser without waste, it is fixed in parallel to the top of the condenser 10 tens of millimeters Open a hole for water to drop every few millimeters in a round pipe of this pipe, rotate this pipe several times per minute with a motor, and drip drain water in order from the right end, and evenly drop to the left end with one turn of the pipe Let
Due to the surface tension of the water coming out of the hole in the pipe, there is a phenomenon that it is difficult for water droplets to fall. Spread a small amount of water evenly

According to the invention of claim 2, even when using water other than drain water, the thermostat is turned on and off depending on the temperature of the high pressure pipe of the condenser, and the electromagnetic valve and the rotary motor are controlled. It is possible to reduce the amount of use.

According to the present invention, in a place where the drain pipe of the air conditioner is taken out together with the outdoor unit pipe at home or office, the power of the air conditioner can be obtained most simply by connecting the drain pipe to the spraying device and receiving power from the outdoor unit power supply. The more drain water that is generated, the more the drain water is generated by the heat of vaporization (539 Kcal / g), which cools the condenser, lowers the pressure of the high pressure, reduces the power consumption, and saves energy without reducing the cooling capacity.
In addition, compared to conventional tap water and groundwater spraying methods, there is less generation of dirt and rust on the equipment, no water charges, no pumps, and low expenses. The power of the motor that rotates the sprinkling pipe is a low speed of several revolutions per minute.
Also, since the drain water is almost evaporated by the condenser, the veranda etc. will not be discolored by moss due to drain drainage.
Even when tap water is sprayed, the amount of water can be greatly reduced by this method.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1-1 to 1-3.
Fig. 1-1 is a plan view of the present invention. The drain water flowing from 4 passes through the water sensor 2 and flows into the rotating pipe 5 and exits from the pilot hole of the pipe. Because the position of the pilot hole is moving from right to left and from left to right in sequence, the drain water is dropped evenly from end to end of the air conditioner condenser. The hole in the pipe is small and may cause water droplets due to surface tension of water, and the guide for guiding the discharged water to the condenser is a brush-like material that is hard to get mold as shown in 6 in Figure 1-3. Make an oblique contact with the rotating pipe.
Spiral holes only come out from the bottom hole when there is little drain water, but if there is a lot of drain water and collects in the pipe, it will come out from the bottom several holes. Can be dripped evenly.

Claims (2)

In the pipe of the outdoor unit condenser with a width of dozens of millimeters in diameter, a hole of about 1 mm is spirally formed at intervals of several millimeters, this drain pipe is rotated several times per minute by a motor, and water droplets are drawn from the end of the condenser A device that sprays evenly to the condenser through warp-shaped resin guides that are dropped sequentially to the end and in contact with the drain pipe. Not only drain water, but also tap water or groundwater can be used to greatly reduce the amount of water, and a thermostat that senses the temperature rise of the high-pressure pipe turns on the solenoid valve of water simultaneously with the rotary motor. Turn it off.
