The present invention relates to an air conditioner, particularly an air conditioner having a radiation panel to remove condensed water formed on the radiation panel during radiation heat exchange using a radiation panel and an evaporator.

As an example of cooling by radiant heat exchange, as shown in FIG. 1, the inside of the tunnel 1 may feel cool even when the temperature is not low, in a hot summer sun. This is because heat of the human body 2 is released by radiant heat exchange with the tunnel wall surface 1a.

The radiative cooling is a method of cooling through radiant heat transfer between the human body and the surface of a cold radiative cooling system. Figure 2 is a graph showing the heat release rate of the human body in the office. As shown in FIG. 2, the office worker working in the office occupies about 45% of the heat emitted by the human body to the outside, which is about twice the heat radiation (23%) due to convection. .

Since the radiant cooling is directly radiant heat exchange with the human body, the comfort is superior to the convection cooling method, and the noise is less than that of the convective heat exchange.

In addition, with the growing interest in environmentally friendly and energy efficient cooling of cooling systems, advanced countries have already been actively researching various types of radiative cooling systems.                         

3 is a schematic diagram of a conventional radiant heat exchange apparatus.

Referring to FIG. 1, the compressor 10 includes a compressor 10, a condenser 20, an expansion valve 30, and a radiant heat exchanger 40. The radiant heat exchanger 40 includes an evaporator 41 and The radiation panel 42 is comprised.

The compressor 10 increases the pressure to a saturation pressure corresponding to the condensation temperature so as to suck the low-temperature low-pressure gas refrigerant evaporated in the evaporator 41 to liquefy condensation in the next condenser 20, and condenser (CONDENSER) 20 is a high-temperature, high-pressure gas refrigerant discharged from the compressor 10 to heat the surrounding air or cooling water to release the heat of the gas refrigerant to condensate the liquid, the expansion valve (EXPANSION VALVE) 30 When the condensed liquefied refrigerant is rapidly released through a narrow place (crossing), the refrigerant is released from the pressure and begins to evaporate, and adjusts an appropriate amount to absorb sufficient heat from the evaporator 41.

As shown in FIG. 4, the evaporator 41 of the radiation panel unit 40 introduces low-temperature low-pressure refrigerant passing through the expansion valve 30 to exchange heat with the object to be cooled, thereby evaporating heat of the refrigerant. To perform the purpose of refrigeration.

Here, the radiation panel 42 is used as the object to be cooled of the evaporator 41. The radiation panel 42 is brought into contact with the evaporator 41 to cool it. At this time, the cooled radiation panel 42 is heat exchanged with the human body 60 present in the room as shown in Figure 4 by the body releases heat, thereby achieving a cooling effect.

However, in order for the radiation panel 42 to exchange heat with the human body, the temperature of the radiation panel 42 should be low (approximately 20 ° C.). If the radiation panel temperature is lower than the dew point, moisture in the atmosphere condenses and radiates. The condensate 50 is formed on the panel, and the condensate 50 flows down the radiation panel 42, causing condensate to accumulate on the floor, and condensate may corrode objects. .

In addition, there is a problem that the condensation water formed on the radiation panel changes the surface shape of the radiation panel to prevent radiant heat transfer.

The present invention has been made to solve the above problems, and provides an air conditioner having a radiation panel to remove the condensate by providing a flow path for the air to flow to the front and rear of the radiation panel attached to the evaporator and the evaporator. Is in.

Another object is to provide a case outside the evaporator and the radiation panel, and to provide a fan inside the case to form the suction and discharge ports, so that the suction air passes through the evaporator and the discharged air flows to the front of the radiation panel, It is an object of the present invention to provide an air conditioner having a radiation panel capable of removing condensate generated in front of the panel.

Hereinafter, with reference to the accompanying drawings as follows.

5 is a configuration diagram of an air conditioner having a radiation panel according to an embodiment of the present invention.

Referring to FIG. 5, an expansion valve 130 connected to the compressor 110, the condenser 120, and the condenser 120; One side is connected to the expansion valve and the other side is composed of a radiant heat exchange means 140 having an evaporator 141 connected to the compressor and a radiation panel 142 attached to the back of the evaporator.

The radiant heat exchanger 140 protects the evaporator 141 and the radiation panel 142, has a case for air intake and discharge, a case 143 with an open front surface of the panel, and an image on the front surface of the case 143. Intake air (143a) and the discharge port (143b) formed in the lower portion, and the suction port 143a and the flow path through the evaporator 142 below the radiation panel 142 to suck air and discharge port (143b) and radiation panel 142 It includes a fan 144 for discharging air to the flow path through the front surface, and a motor 145 for driving the fan 144.

Referring to the accompanying drawings, an air conditioner having a radiation panel according to the present invention configured as described above is as follows.

Referring to FIG. 5, the compressor 110 is connected to the evaporator 141 of the radiant heat exchanger 140, and sucks gas refrigerant of low temperature and low pressure evaporated from the evaporator 141 to liquefy condensation in the condenser 120. Increase the pressure to the saturation pressure corresponding to the condensation temperature.

The condenser 120 heat-exchanges the high-temperature, high-pressure gas refrigerant discharged from the compressor 110 with ambient air or cooling water to release heat of the gas refrigerant to condense the liquid.

In addition, the expansion valve 130 is connected to the condenser 120 and the pipe, and discharges the refrigerant condensed liquefied from the condenser 120 to a wide place through a narrow place. At this time, the refrigerant is released from the pressure begins to evaporate, and adjusts the appropriate amount to absorb enough heat in the evaporator.

That is, the expansion valve 130 is connected between the condenser 120 and the evaporator 141 of the radiant heat exchanger 140, and when the radiant heat exchanger 140 performs the operation mode, the refrigerant having a low temperature and low pressure is used. It discharges to the evaporator 141 of the radiation heat exchange means 140. At this time, the radiant heat exchanger 140 cools the radiant panel 142 by the evaporator 141 and performs radiant heat exchange with a heat exchange target (eg, a human body) by the radiated panel 142 cooled. Have

To this end, the radiant heat exchange means 140 is provided with an evaporator 141 and a radiation panel 142, and a component for removing condensate (hereinafter abbreviated as "condensate removal unit"), the condensate removal unit ( Reference numeral) is a configuration including a case 143 having a suction port 143a and a discharge port 143b, a fan 144 inside the case, and a motor 145 axially connected to the fan 144 for driving the fan.

The evaporator 141 is connected between the expansion valve 130 and the compressor 110 and is coupled to the rear surface of the radiation panel 142, and the radiation panel 142 with the low temperature and low pressure refrigerant discharged from the expansion valve 130. Cool it down. At this time, the cooled radiation panel 142 performs a cooling effect by performing radiation heat exchange with the human body.

In addition, the case 143 is spaced apart from the outer surface of the evaporator 141 and the radiation panel 142 by a predetermined distance, and a circulation flow path is formed between the inner surface of the case 143 and the outer surface of the evaporator 141 and the radiation panel 142. Have Then, the front surface of the panel is opened to include the suction port 143a and the discharge port 143b in the upper and lower parts.                     

In addition, the fan 144 is connected to the motor 145 at the rear upper side of the case 143 to suck air through the suction port 143a, and dehumidification when the sucked air passes through the evaporator 141 side flow path. The dehumidified air is sucked and discharged to the upper side of the case.

The dehumidified air discharged is discharged through the discharge port 143b. At this time, since the shape of the discharge port 143b extends to the upper surface of the upper end of the radiation panel 142 in a shape of “┐”, the air discharged through the discharge port 143b is directed downward along the front surface of the radiation panel 142. Flows into. Accordingly, the condensed water 150 generated on the surface of the radiation panel 142 is removed.

That is, when the temperature of the radiation panel 142 is below the dew point of the atmosphere, the atmospheric water vapor becomes saturated and condenses on the surface of the radiation panel 142 to generate condensed water 150. If there is air, the saturated atmosphere is in contact with the dehumidified air, not in contact with the radiation panel 142, and thus only increases the humidity of the dehumidified air and does not condense on the surface of the radiation panel.

 In this way, the inlet port 143a and the outlet port 143b on the front surface of the case 140 and the flow passage through the evaporator 141 therein, the dry air dehumidified while passing through the evaporator 141, the radiation panel By passing through the front surface, the dry air absorbs and removes the condensed water 150 on the radiation panel 141.

6 is another embodiment of the present invention.

Referring to FIG. 6, the shapes of the suction port 243a and the discharge port 243b of the case 243 can be easily sucked and discharged, and the air flow path can be virtually made in front of the radiation panel 242. The inlet port 243a is a "┘" shape projecting upwardly spaced apart from the bottom of the radiation panel 242 by a predetermined interval, and the discharge port 243b is a "B" shape projecting downwardly spaced apart by a predetermined space below the radiation panel 242. Has

Therefore, the suction port 243a of the case 243 sucks air flowing in front of the radiation panel, and the sucked air is dehumidified in the evaporator 241 and sucked into the fan 244 and discharged, and the discharged air is dehumidified ( Iv) The discharged air is discharged downward along the entire surface of the radiation panel 242 through the discharge port 243b, whereby the air on the radiation panel 242 becomes saturated due to the dehumidified air, and the air contacts the radiation panel. Instead of contacting the dehumidified air, it can eliminate condensate generation that condenses on the radiation panel surface.

According to the present invention, the shape of the case may be changed to a curved shape so as to generate less noise during suction and discharge, and the structure of the suction and discharge ports may also be changed to a structure in which air is sucked or discharged to the front of the radiation panel. There is also.

According to the air conditioner having a radiation panel according to the present invention as described above, it is possible to remove the condensed water on the surface of the radiation panel generated during the radiation heat exchange using the evaporator and the radiation panel, thereby reducing the inconvenience caused by the flowing condensate It is effective in eliminating and reducing radiant heat transfer by condensate.                     

In addition, by making a condensate to remove the condensed water around the evaporator and the radiation panel, by dehumidifying the air on the radiation panel by using the evaporator, there is an effect that does not need to provide a separate dehumidification device.
