Abstract

PURPOSE:To enable to obtain a refrigeration cycle by improving a radiation effect, by a method wherein dehumidified water obtained by an evaporator and water accumulated in a water tank are cooled by spraying them over condenser and blowing part of cool air against the condenser further. CONSTITUTION:When a compressor 18, a motor 7 and a pump 21 are operated, a coolant of a high temperature is streamed to a condenser 15, the coolant is liquidized by cooling the coolant by touching air sucked through a suction opening 4 by a sirocco fan 9 to the condenser 15, the liquidized coolant is streamed to an evaporator 12, the coolant is evaporated by touching air sucked through a suction opening 3 by a siroco fan 8 to the evaporator 12, the air sucked through the suction opening 3 and turned into cool air is guided by an air guide 10 and supplied to a predetermined position. In this instance, part of the cool air in the air guide 10 passing through a pipe 17 is blown against the condenser by a cool air sprayer 16. On the one hand, water in a water tank 19 is pumped up by the pump 21 and the condenser 15 is watered by watering device 22. In addition to the above matter, upon receipt of drain dropping from the evaporator 12 by a drain pan 13 the drain is led to a place above the condenser 15, through which the condenser is watered.

Description

Detailed Description of the Invention The present invention is a cooling fan that sprays dehumidified water obtained by an evaporator and water stored in a water tank into a condenser and condenses a part of the cold air. The blower on the container is related to a cold fan that cools the container.

Structure of the conventional example and its problems In the conventional cooling fan, as shown in FIG. Tank 104 was taken out from the machine and drained. In addition, the heat dissipation of the condenser 105 takes indoor air and releases it to the outside of the machine through the motor 106, blades 107, and casing 108. Therefore, the heat dissipation effect is poor especially when the room temperature is high, and the refrigeration efficiency is reduced. was there.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks by spraying dehumidified water obtained from an evaporator and water stored in a water tank into a condenser, and further condensing a part of the cold air. The purpose of the present invention is to provide a cooling fan that cools the fan, enhances the heat dissipation effect, and provides a highly efficient refrigeration cycle.

Composition of the Invention The cooling fan of the present invention includes a refrigeration cycle formed by equipment such as a compressor, a condenser, and an evaporator, and has a water tank at the bottom of the condenser. In order to achieve this goal, a pipe is installed via a pump, and a spray section is installed at the tip of the pipe, and a portion of the cold air obtained from the evaporator is introduced into the air intake side of the condenser through the pipe and sprayed onto the condenser. It is a cooling fan.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

In the figure, reference numeral 1 denotes a main body of a cooling fan provided with an air outlet 2. Suction ports 3 and 4 are provided on the side of the main body 1, and a cover 6 from which a supplementary water tank 5 can be taken out is provided on the front.

7 is a motor with sirocco fans 8.9 installed on both shafts, 10
, 11 is an air guide for the sirocco fans 8 and 9, 12 is an evaporator, and below it is a drain pan 13 and a drain pipe 14.
is provided to flow dehumidified water into the condenser 15. ℃
A part of the cold air obtained by passing through the evaporator 12 is sent to the condenser 1.
A pipe 17 connects the air guide 10 so that it communicates with the inside of the air guide 10 by a cold air blower that blows the air into the air guide 5. 18 is a compressor that sends the refrigerant to the condenser 15 and the evaporator 12; 19 is a water tank that stores water to be sprinkled on the condenser 15; 20 is a pipe that sucks up water from the water tank 19; a pump 21 is provided in the middle; A water sprinkler 22 for sprinkling water on the condenser 15 is provided at the tip. The replenishment water tank 5 is used to replenish water to the water tank 19 so that the water level in the water tank 19 is always at a constant level, and a valve 23 is provided at the bottom.

24 and 25 are filters provided at each of the suction ports 3 and 4.

In the above configuration, the compressor 18, the motor 7, the pump 21
When the engine is operated, high-temperature refrigerant flows into the condenser 15, and air sucked in from the suction port 4 by the lock fan 9 flows into the condenser 15.
The liquefied refrigerant flows into the evaporator 12, and air drawn from the suction port 3 by the sirocco fan 8 comes into contact with the evaporator 12, and the refrigerant is liquefied. is vaporized, and the air sucked through the suction port 3 becomes cold air and is guided to the air guide 10 and blown to a predetermined location. At this time, part of the cold air in the air guide 10 passes through the pipe 17 and is sent to the condenser 1 by the cold air blower 16.
It is sprayed on 5. On the other hand, water from the water tank 19 is sucked up by the pump 21, and water is sprinkled on one side of the condenser by the sprinkler 22. Furthermore, the drain dripping from the evaporator 12 is in the drain pan 1.
3, the condenser 15 is drained by the drain pipe 14.
The condenser 16 is guided upward and sprinkled with water into the condenser 15, and the condenser 16 receives the air flow sucked in from the suction port 4 by the sirocco fan 9, the cold air blown by the cold air blower 16, the water sprinkled from the water sprinkler 22, and the drain. The cooling efficiency of the condenser 15 is increased by sprinkling drain water from the pipe 14.

Effects of the Invention As described above, according to the present invention, a water tank is installed at the bottom of the condenser.
A tank is installed in the tank, and a pipe is installed above the water tank via a pump, and a water sprinkler is installed at the tip of the pipe. It is introduced into the air intake side of the condenser and sprayed onto the condenser, which has a higher cooling effect than dissipating heat only at room temperature, making it possible to improve the efficiency of the refrigeration cycle. Since dust is removed by this process, dust does not adhere to the condenser surface and the condenser can be used as an efficient condenser anytime, making it possible to obtain a cooling fan with a highly efficient refrigeration cycle. It is something to do.
