Description

Air conditioner with heat exchanger equipped with heating pipe {AIR-CONDITIONING AND HEATING EQUIPMENT}

The present invention relates to an air conditioner that uses both a cooler and a heater, and provides a configuration capable of heating and cooling without incorporating a separate heating pipe on the upper side of the main body as in the prior art, and when the heating the refrigerant compressed in the compressor Flows to the first exchanger side of the heat exchanger, and then flows through the expansion valve to the heat exchanger side of the second heat exchanger and heats it to a proper temperature at room temperature by a heating pipe to increase the compression efficiency of the refrigerant and circulate to the compressor side. It is possible to supply the indoor hot air from the upper first heat exchanger, and during cooling, the compressed refrigerant passes through the heat exchanger of the second heat exchanger first, and then the heater of the heating pipe is turned off. Flows to the first heat exchange part that is in a state of The cooling air is supplied to the room, and the condensation water generated by the temperature difference on the outer surface by heat exchange from the first heat exchanger is discharged to the outside, thereby enabling the heating and cooling of the air conditioner by a relatively simple configuration, as well as heating. The present invention relates to an air conditioner to which a heat exchanger equipped with a heating pipe for increasing heat exchange efficiency as well as a significant reduction in maintenance cost of an air conditioner by making it possible to significantly reduce power consumption at a time.

In general, the air conditioner refers to a device that selectively realizes cooling and heating by two heat exchangers alternately performing the roles of an evaporator and a condenser. The first heat exchanger and the second heat exchanger, respectively, serve as heat exchangers and evaporators. Cooling and heating are realized as the refrigerant is circulated or reversely circulated through alternating heating and cooling cycles with a continuous process of compression-condensation-expansion-evaporation.

In the case of such a heating and cooling device, there are utility model registration No. 400067 and utility model registration No. 379764 previously filed and registered with the Korean Intellectual Property Office.

In the case of the prior art, an air conditioner without an outdoor unit is proposed by additionally installing a 4-way directional valve, a heating heater, and an auxiliary heater inside the main body, and converting the same to a cooling device or a heating device.

In the case of the prior art, after spraying the water supplied from the water tank to the second heat exchanger upwards, the water is dropped into a fine foam through the upper injection plate, and the second heat exchanger is cooled or heated. Since it comes into contact with the heat exchanger pipe, its efficiency is insignificant, and high or low temperature water dropping between the pipe and the pipe is insufficient, as well as cold air is introduced during the heating operation by the outdoor air supplied through the intake pipe. In the cooling operation, a relatively high temperature of the air is introduced, and thus the heat exchange efficiency of the second heat exchange part is inevitably reduced. As described above, a separate configuration for cooling or heating the second heat exchange part must be provided. Therefore, there is a problem in that the internal structure of the air conditioner is complicated and the cost increases accordingly. The.

In addition, in the case of the Republic of Korea Patent Publication No. 2006-53572, the compressor can fully exhibit the original function when heating, but it is possible to realize a high level of heating performance by a pure heating cycle without a separate electric heater, when cooling Adjacent intake fan and exhaust fan arranged in series are complementary to provide airflow in all the condensing chambers to provide high efficiency cooling performance for outdoor unit integrated air conditioner.

However, in the case of the above-mentioned patent, it relates to an air-cooled air-conditioning device, wherein the first heat exchanger at the bottom of the casing has a cramped shape, and the air passing therethrough has a duct shape from the bottom to the upper side through two fans forming an axial flow fan and a centrifugal fan. Flow along the discharge pipe to be discharged to the indoor side, the heat loss in the convection process can not overcome the problem.

In addition, two expansion valves (or capillaries) connected to each other through the first heat exchanger and the compressor are provided. The heating and cooling flows are independently performed, and the cooling and the heating are switched according to the operation type. Likewise, since each heating and cooling system is formed in one casing, the manufacturing cost of the air conditioner is significantly increased, and the maintenance is difficult.

Therefore, in the case of air conditioners currently produced or sold by related companies, each component provided to selectively use heating and cooling is complicated, and production costs associated with the configuration are considerably solved. It is not.

In addition, the Republic of Korea Patent Registration No. 10-2008-0135196 was devised by the applicant, but through the outside air outlet that the warm air in the heat exchanged state is provided to the rear side of the main body according to the operation of the air blow fan formed in the middle portion of the main body during cooling In this configuration, the distance between the rear side of the main body and the wall must be spaced apart, or a complicated work requirement for allowing the external air outlet to be discharged to the outside by drilling a hole in the wall body separately. You will need

In addition, in the case of the patent, it has been pointed out that a separate blower should be additionally configured in the central portion of the main body.

Accordingly, the present invention has been made to solve the above-mentioned other problems and technical problems of the prior application patent devised by the present applicant,

In order to heat the direct water supplied to the heat exchanger during heating, the heater passes through the heating pipe in which it is inserted, and then the hot water heated by the heat exchanger is supplied to enable heating, and during cooling, the heater is controlled so as not to operate the heater of the heating pipe. By allowing the inside of the heat exchanger to flow by cold water, a series of processes to cool the refrigerant pipe inside the heat exchanger to induce the flow of the refrigerant are selectable, simplifying the internal structure of the air conditioner and making it accordingly. In addition to the remarkable reduction of the cost, the purpose is to reduce the power consumption during heating and at the same time increase the thermal efficiency.

The fourth space part 40 is provided with a second heat exchange part 500. The second heat exchange part 500 is a heat exchanger 510 at the bottom of the heat exchanger 510 as shown in FIGS. 3, 4 and 6. ) Is provided with a support 520 for fixing.

The heat exchanger 510 is formed of a copper tube, and forms one tube on the outside as shown in FIGS. 3 to 4, and has a form in which a refrigerant tube 513 of a multi-pipe type is arranged therein.

That is, the heat exchanger 510 is formed by winding a copper pipe as shown in FIG. 4, and a first refrigerant mixture sphere 511 and a second refrigerant mixture sphere 512 are formed at both ends, respectively, and the heat exchanger 510 is formed. In the copper pipe forming a), as shown in the partial enlarged cross-sectional view of FIG.

Therefore, the second branch pipe 210 branched from the 4-way valve 200 and the first refrigerant mixture sphere 511 in the heat exchanger 510 are connected to each other, and the heat exchanger 510 flows and is formed at the end thereof. The second refrigerant mixture sphere 512 is connected to the expansion valve 310 has a structure.

On the other hand, the water is supplied to the inside of the copper pipe of the heat exchanger 510 has a configuration that the heating pipe 520 is provided on the side of the heat exchanger 510 as shown in FIG.

The water flowed through 520 was allowed to flow into the heat exchanger (510).

Therefore, in the air conditioner to which the present invention is applied, when the air is cooled, the external direct water passes through the heating pipe 520 in the state of turning off the heater 521 to be inserted into the inside of the heating pipe 520 (that is, the coolant And the refrigerant flowing into the heat exchanger 510 and compressed in the compressed state by the compressor 100 flows to the heat exchanger 510 and then cools and flows to the upper first heat exchanger 300. To ensure that cold goods are supplied by heat exchange with outside air, and then flows into the compressor 100 through the 4-way valve 200,

Alternatively, during heating, the refrigerant supplied from the compressor 100 is allowed to flow to the first heat exchange part 300 through the 4-way valve 200, and the hot air is supplied after the heat exchange. The refrigerant is induced to be supplied to the side of 510, but the direct water supplied to the heating pipe 520 is appropriately set at room temperature while the heater 521 in the heating pipe 520 connected to the heat exchanger 510 is turned on. By heating to a temperature (20 ~ 40 °) to induce the introduction of water of the appropriate room temperature to the heat exchanger 510 side, the heat exchanger for the liquid refrigerant in the ultra low temperature induced by the heat exchanger 510 to room temperature and then After the four-way valve 200 is returned to the compressor 100 side, the above-described process is repeated, and a high temperature warm air is supplied to the indoor side.

On the other hand, the heating pipe 520 added to the side of the heat exchanger 510 in the second heat exchange unit 500 is always preferred to maintain a proper temperature at room temperature, the temperature is 20 to 40 as described above It is desirable to maintain °.

To this end, by attaching a temperature sensor (S) to the outer peripheral surface of the appropriate portion of the heating pipe 520, when the temperature of the direct water in the heating pipe 520 is more than the set range, the heater 521 is turned off, If the temperature of the direct water in the heating pipe 520 is less than the appropriate temperature in the state, the operation to turn on the heater 521 is automatically repeated so that the direct water that has always been raised to the proper temperature is the heat exchanger of the second heat exchanger 500. It is desirable to be able to supply to the machine 510.

As shown in FIGS. 5 to 6, the fifth space part 50 is provided with a dew condensation drain part 600 and a compressor 100, and includes a first heat exchange part provided in the uppermost first space part 10 ( Condensation water generated during cooling at 300 is induced to be stored inflow into the condensation water drain unit 600, and the stored condensation water is driven by a motor (not shown) provided in the condensation water drain unit 600. To be discharged to the outside.

In addition, as described above, the compressor 100 is configured to be connected to the refrigerant discharge pipe 110 for discharging the compressed refrigerant and the refrigerant recovery pipe 120 for recovering the flowed refrigerant again. As described above, the refrigerant discharge pipe 110 is connected to the upper surface side of the 4-way valve 200, and the refrigerant recovery pipe 120 is connected to the lower end side of the 4-way valve 200.

The flow at the time of cooling or heating is demonstrated using this invention which has the above-mentioned structure.

Looking first with reference to Figure 5 the operating flow of the present invention when cooling,

When power is applied to the main body 1 from the outside, the compressor 100 is operated to circulate the refrigerant. The refrigerant is discharged from the compressor 100 through the refrigerant discharge pipe 110 to the 4-way valve 200. After being introduced, it is discharged through the second branch pipe 220 leading to the lower side from the 4-way valve 200.

The refrigerant discharged as described above is introduced into the heat exchanger 510 through the first refrigerant mixture sphere 511 of one end of the heat exchanger 510 of the second heat exchanger 500, and the first refrigerant mixture sphere 511. The refrigerant pipe 513 leading to the inside of the copper pipe constituting the heat exchanger 510 forms a plurality of multiple tubes as shown in FIG. 4, and as described above, flows into the first refrigerant mixture sphere 511. The refrigerant has a flow in which the refrigerant flows into and flows into the plurality of refrigerant pipes 513 described above as multiple pipes.

As described above, the refrigerant introduced through the second branch pipe 220 is circulated after being introduced to the heat exchanger 510. At this time, the refrigerant maintains a gas state of high temperature and high pressure, and flows through the heat exchanger 510. Since it is necessary to heat exchange, the refrigerant should be cooled to a liquid state of medium temperature and high pressure by water (that is, direct water) supplied from the outside to the heat exchanger 510.

At this time, as described above, the inside of the copper pipe of the heat exchanger 510 surrounding the plurality of refrigerant pipes 513 formed of the multiple pipes is supplied with water directly from the outside, the supplied water is the heating pipe 520 After flowing into the direct inlet 522 and passing through the heating pipe 520, and then introduced into the one end side of the heat exchanger 510 through the direct outlet 523 leading to the other end of the heating pipe 520, the heat exchanger ( The refrigerant flowing in the refrigerant pipe 513 in contact with the outer circumferential surface of the refrigerant pipe 513 formed of multiple pipes 510 is cooled.

At this time, the heater 521 embedded in the heating pipe 520 is in an off state, and the first branch pipe 210 is in a state of being blocked by the 4-way valve 200.

The coolant flowing through the coolant tube 513 as described above is discharged from the heat exchanger 510, and the coolant that has passed through the heat exchanger 510 while maintaining the state of being cooled in the liquid state through the heat exchange process described above is a main body. (1) is guided to the first heat exchange part 300 side accommodated in the first space portion 10 of the upper bar, the refrigerant before the induction into the first heat exchange part 300 side the expansion valve 310 (aka capillary tube) Passing through, the liquefied refrigerant flows into the low temperature and low pressure state.

In addition, when the low-temperature low-pressure refrigerant flows to the first heat exchange unit 300, the first blower 400 accommodated in the second space portion 20 is in the operating state of the first blower 400 According to the operation, as shown in FIG. 5, the outside air introduced through the outside air tool 21 is convection to the first space part 10 and is heat-exchanged with cold air while passing through the first heat exchange part 300. Through the outlet 11 in front of the cool air is passed through a series of processes to be supplied to the room.

On the other hand, if you look at the operating flow of the present invention when heating,

When power is applied to the main body 1 from the outside, the compressor 100 is operated to circulate the refrigerant. In the compressor 100, the refrigerant is discharged into the refrigerant of high temperature and high pressure through the refrigerant discharge pipe 110, and thus the 4-way. After flowing into the valve 200, the refrigerant flows to the first branch pipe 210 as opposed to the flow at the time of cooling according to the change of the 4-way valve 200, and passes through the first heat exchange part 300. When the refrigerant in the high temperature and high pressure gas state flows into the first heat exchange part 300, the first blower 400 accommodated in the second space part 20 is in an operating state, and the first blower 400 is in operation. As shown in Figure 5 according to the operation of the outside air introduced through the outdoor air tool 21 is convection to the first space portion 10 and passing through the first heat exchange unit 300, the heat exchange with hot air, then the main body ( 1) Through the outlet 11 of the front is subjected to a series of processes in which warm warm air is supplied to the room.

Meanwhile, the heat exchanged refrigerant has an expansion valve 310 formed of a capillary tube, and changes to a low temperature low pressure state while passing through the expansion valve 310 to flow to the heat exchanger 510 of the second heat exchanger 500.

In this way, the refrigerant passing through the expansion valve 310 is introduced into the heat exchanger 510 side of the second heat exchanger 500. In order to increase the heat exchange efficiency of the heat exchanger 500, a temperature is applied to the heat exchanger 500. It is preferable to provide the sensor S to control the operation of the heater 521.

Therefore, the heater 521 is kept heated by the on-operation of the heater 521, and the external direct water inlet 522 is directed to the heating pipe 520 in which the heater 521 is introduced. Supplied by a separate pumping means not shown through, the direct water flowing through the direct inlet 522 is subjected to a process of heating by the heater 521.

The direct water heated by the heater 521 flows through the heating pipe 520 as a whole, and then flows into the heat exchanger 510 through the direct water outlet 523 connected to the other end of the heating pipe 520. Have

Therefore, when the refrigerant introduced into the heat exchanger 510 at a low temperature and low pressure flows along the multi-pipe inside the copper pipe of the heat exchanger 510, the high temperature water introduced through the direct water outlet 523 is also a heat exchanger. It flows into the copper pipe of 510, and changes phase into a gas state by the heat exchange in the heat exchanger 510. FIG.

At this time, the heater 521 in the heating pipe 520 is a temperature sensor (as described above) on the outer peripheral surface of the appropriate portion of the heating pipe 520 in order to be able to selectively turn on / off according to the temperature variation of the number of supplied direct water It is preferable to have S).

That is, the temperature of the direct water flowing into the heating pipe 520 can be maintained in the set temperature range after the flow sensor of the heating pipe 520 is set to maintain the proper temperature at all times by the temperature sensor (S). The heater 521 is adjusted on / off so as to be on.

As such, the refrigerant flowing in the ultra low temperature state is introduced into the 4-way valve 200 in the state of being heat-exchanged at room temperature, and then recovered to the compressor 100 through the refrigerant recovery pipe 120. After being compressed to high temperature and high pressure in the compressor 100, the above series of processes are repeatedly repeated through the refrigerant discharge pipe 110.

In addition, as described above, the first blower 400 accommodated in the second space part 20 is operated to discharge the heat generated by the high temperature refrigerant passing through the first heat exchange part 300 to the indoor side. After introducing the outside air through the outdoor air tool 21 in the convection to the first heat exchange unit 300 on the upper side, passing through the first heat exchange unit 300 to heat exchange with a high temperature warm air after the main body ( 1) Through the outlet 11 of the front side is repeated a series of heating flow to allow the warm air is discharged to the indoor side.

On the other hand, when the cool air is blown by the blower 400 and the low-temperature refrigerant passing through the first heat exchange unit 300 in the cooling process as described above, the first heat exchange unit 300 by the cryogenic refrigerant The condensation water generated on the outer surface side is naturally accumulated to the lower side of the first space part 10, and then the condensation water is discharged to the drain pipe 610 connected through the lower end of the first space part 10. Through the condensation water drain 600 provided in the fifth space part 50 at the lower end through the drop collection.

The condensation water collected in a predetermined amount is subjected to a process of being extracted to the outside of the main body 1 by a pump (not shown) provided separately in the condensation water drain unit 600.
