Description

{Method for controlling thermoelectric module air conditioner}

The present invention relates to a thermoelectric air conditioner, and more particularly, to a control method of the thermoelectric air conditioner for performing cooling using a thermoelectric module.

Thermoelectric module is used as a thermoelectric conditioner or heating device by connecting in series a plurality of thermoelectric elements having a Peltier effect, in which one end generates heat and the other end absorbs heat when DC is applied to both ends. module that becomes

The thermoelectric module as described above consists of a heat absorbing part or a heat dissipating part that absorbs heat, and a heat dissipation member such as a heat dissipation fin or a heat dissipation block is coupled to the heat absorbing part or the heat dissipating part to increase heat transfer efficiency when used as a thermoelectric air conditioner or a heating device.

As an example of the conventional thermoelectric air conditioner, there are Patent Documents 1 to 3 and the like.

For example, in the case of the thermoelectric air conditioner according to Patent Documents 1 to 3, a heat absorbing part and a heat dissipating part are provided, and air is passed through the heat absorbing part to perform cooling.

On the other hand, in the conventional thermoelectric air conditioner, a thermoelectric module, a first heat exchange part coupled to a heat dissipation part of the thermoelectric module, and a second heat exchange part coupled to a heat absorbing part of the thermoelectric module are generally configured as a plurality of sets.

In addition, the conventional thermoelectric air conditioner selectively performs the cooling mode and the dehumidifying mode because the amount of air passing through the second heat exchanger must be minimized in order to obtain a dehumidifying effect when the dehumidifying mode is performed.

However, when the cooling mode and the dehumidifying mode are selectively performed, there is a problem in that the efficiency of the thermoelectric air conditioner is lowered.

Furthermore, when the dehumidification mode is executed, cooling is practically impossible due to the minimization of the air volume, so there is a problem in that the ambient temperature rises when the dehumidification mode is executed.

The condensed water storage unit 910 is configured to store condensed water generated in the second heat exchange unit while the second heat exchange unit exchanges heat, and various configurations are possible.

For example, the condensed water storage unit 910 is located at a lower position than the second heat exchange unit in consideration of the flow of condensed water from the second heat exchange unit in a position within the housing 400 , and is installed in the housing 400 . Accordingly, the shape and structure may have various shapes.

As an example, the overall shape of the condensed water storage unit 910 preferably has a shape by a combination of one or more rectangles, has a container structure in consideration of storing condensed water, and has an open upper storage housing 911 ) and may include a cover member 912 covering the opening of the storage housing 911 .

Accordingly, in the storage housing 911, one or more discharge openings 913 through which the mist generated inside the storage housing 911 is discharged to the outside and the air for discharging the mist through the discharge opening 913 forms a mist flow One or more inlet openings 914 introduced from the outside by the part 930 may be formed in the sidewall.

The discharge opening 913 is formed on the sidewall of the storage housing 911 and is an opening through which the mist generated inside the storage housing 911 is discharged to the outside, and is sufficiently higher than the water level of the condensed water stored in the storage housing 911 It is preferably formed in the position.

On the other hand, on the outer surface of the side wall of the storage housing 911 in which the discharge opening 913 is formed, a flow guide part 941 for guiding the flow of the mist may be installed.

The flow guide part 941 is a configuration that is installed on the outer surface of the side wall of the storage housing 911 in which the discharge opening 913 is formed to guide the flow of the mist, and various configurations are possible.

As an example, the flow guide part 941 may be configured as a guide member extending upward from the outer surface of the side wall of the storage housing 911 as it is preferable that the mist flows upwards of the storage housing 911 .

The inlet opening 914 is an opening formed on the side wall of the storage housing 911 through which air for discharging the mist through the discharge opening 913 is introduced from the outside by the mist flow forming unit 930, and the storage housing (911) It is preferable to be formed at a position sufficiently higher than the water level of the condensed water stored therein.

On the other hand, when air is introduced through the inlet opening 914, the air through the inlet opening 914 is directed upward so as not to interfere with the operation of the ultrasonic unit 920 such as a water column 901 generated by the ultrasonic unit 920 to be described later. An air guide part 942 for guiding the direction may be installed on the inner surface of the side wall of the storage housing 911 .

The air guide part 942 is installed on the inner surface of the side wall of the storage housing 911 to guide the air through the inlet opening 914 toward the upper side, and various configurations are possible.

As an example, the air guide unit 942 may be configured as a guide member extending upward from the inner surface of the side wall of the storage housing 911 .

Meanwhile, the condensed water storage unit 910 receives the condensed water generated in the second heat exchange unit by various structures and methods, for example, a pipe 902 connected to the cooling flow path forming unit 200 constituting the second heat exchange unit. ) may be connected to the cover member 912 .

At this time, the cover member 912, a pipe connection structure for connecting the pipe 902 may be installed, and the condensed water inlet 903 through the pipe 902 is a condensed water storage unit so that the condensed water can be stably introduced. It is desirable to extend sufficiently to the bottom of 910 .

Meanwhile, in the condensed water storage unit 910 , a water level sensor 943 for measuring the amount of stored condensed water and controlling the operation of the ultrasonic unit 920 is preferably installed.

The water level sensor 943 is a water level sensor for measuring the amount of stored condensate and controlling the operation of the ultrasonic unit 920 , and various configurations are possible according to the water level measurement method.

The ultrasonic unit 920 is a configuration that forms small water particles, that is, mist by ultrasonic waves for the condensed water stored in the condensed water storage unit 910, and is installed in the condensed water storage unit 910 and generates ultrasonic waves. It may include a 921 and an operation unit 922 for operating and controlling the vibrator 921 .

Here, in order to generate a sufficient amount of mist for improving the heat exchange efficiency of the first heat exchanger to be described later for the condensed water stored in the condensed water storage unit 910, rather than applying the same principle as a general humidifier, as shown in FIG. 23c , condensed water It is preferable to strongly drive the vibrator 921 to such an extent that the water column 901 is generated inside the storage unit 910 .

Meanwhile, the thermoelectric conditioner to which the control method of the thermoelectric air conditioner according to the present invention is applied includes a temperature sensor (not shown) for directly or indirectly measuring the temperature of air, and a humidity sensor (not shown) for measuring the humidity contained in the air. ) is installed.

The temperature sensor is a sensor for directly or indirectly measuring the temperature of the air to be cooled, and may be installed at various positions according to the control purpose.

As an example, the temperature sensor is located in a specific space, for example, in the vicinity of the cooling suction unit 210 on the suction side where the air to be cooled is sucked as the temperature control target is air when the air in the first space is to be cooled. installed is preferred.

As another example, the temperature sensor may be coupled to a specific member to indirectly measure the temperature of the air.

In addition, when the cooling target is a member cooled through air, the temperature sensor may be coupled to the member to measure the temperature instead of measuring the temperature of the air.

The humidity sensor, as a sensor for measuring the humidity contained in the air, may be installed at an appropriate location.

For example, the humidity sensor is preferably installed in the vicinity of the cooling inlet 210, since it is preferable to measure the humidity of the air from which moisture is to be removed.

On the other hand, in the thermoelectric air conditioner to which the control method of the thermoelectric air conditioner according to the present invention is applied, as shown in FIG. 24 , a plurality of heat exchange units 100 are disposed based on the flow direction of air in the cooling passage CF. In particular, the air is sucked from the first space through the cooling inlet 210, and the cooled air passes through the second heat exchange unit 130 of each thermoelectric module unit 100 sequentially through the cooling outlet ( It is assumed that the cooling flow path CF is set to discharge to the first space through 220).

The control method of the thermoelectric air conditioner having the above configuration includes a cooling mode performing step (S10) of cooling the air until the measured temperature of the air measured by the temperature sensor reaches a set cooling temperature range (S10); After the measurement temperature reaches the preset cooling temperature range input by performing the performing step (S10), the moisture contained in the air until the humidity of the air measured by the humidity sensor reaches the preset set humidity range It may include a dehumidifying mode performing step (S20) of removing the.

The cooling mode performing step (S10) is a step of cooling the air until the measured temperature of the air measured by the temperature sensor reaches a set cooling temperature range, and may be performed by various methods.

The measured temperature, as the temperature of the air measured by the temperature sensor, may be measured at a preset period.

The cooling temperature range is defined as a preset set temperature ( _TS ) + an error range (ΔT).

For example, the set temperature ( _TS ) is 25 ℃ and the error range (ΔT) may be defined as 2 ℃.

Meanwhile, in order to perform the cooling mode performing step (S10), the measured temperature of the air may be excessively lower than the set temperature ( _TS ), so it is necessary to correct this.

At this time, in the cooling mode performing step (S10), when the measured temperature is smaller than the set temperature ( _TS ), the direction of the current applied to the thermoelectric module of the thermoelectric module unit 100 is reversely controlled to change the functions of the heat dissipation unit and the heat absorbing unit. The second heat exchange unit 130 dissipates heat to increase the temperature of the air flowing through the second heat exchange unit 130 , thereby correcting that the measured temperature of the air is excessively lower than the set temperature T _S .

On the other hand, in the cooling mode performing step (S10), when the measured temperature measured by the temperature sensor falls too _small than the set temperature (TS ), the direction of the current applied to the thermoelectric module of the thermoelectric module unit 100 is reversely controlled. may not be enough.

In particular, in the cooling mode performing step (S10), when the measured temperature drops to an excessively low temperature, a quick replacement is required.

Accordingly, the thermoelectric air conditioner according to the present invention is installed on the cooling flow path (CF) and, when the measured temperature drops to an excessively low temperature, reaches the set temperature ( _TS ) or within the error range (ΔT) than the set temperature ( _TS ), That is, an auxiliary heater (not shown) for heating air within the cooling temperature range and/or an auxiliary heater (not shown) for heating the panel in case of cooling of a structure such as a panel may be additionally included.

The auxiliary heater is installed on the cooling flow path (CF) and/or on the panel, and when the measured temperature measured by the temperature sensor falls to an excessively low temperature, the set temperature ( _TS ) is reached or higher than the set temperature ( _TS ) An auxiliary heater (not shown) that heats air within the error range (ΔT), that is, within the cooling temperature range, and/or a configuration that heats the panel in case of cooling of a structure such as a panel. It consists of a plate heater, a halogen heater, a ceramic heater, etc. can be

For example, when the temperature measured by the temperature sensor is too low, for example, when the set temperature ( _TS ) is 25°C and the drop temperature is ±2°C or more, the auxiliary heater is on the cooling passage (CF). _{Auxiliary heater} (not shown) and /or may be actuated to heat the panel in case of cooling of a structure such as a panel.

On the other hand, after the temperature correction, if the measured temperature reaches the set temperature ( _TS ) or is within the error range (ΔT) than the set temperature ( _TS ), that is, within the cooling temperature range, the dehumidifying mode performing step (S20) described later is performed. do.

On the other hand, after the temperature correction, if the measured temperature reaches the set temperature ( _TS ) or is within the error range (ΔT) than the set temperature ( _TS ), that is, within the cooling temperature range, the dehumidifying mode performing step (S20) described later is performed. do.

In the dehumidifying mode performing step (S20), the set cooling temperature range (preset set temperature ( _TS ) + error range (ΔT)) into which the measured temperature is input in advance is reached by performing the cooling mode performing step (S10). After that, until the humidity of the air measured by the humidity sensor reaches a preset humidity range, the step of removing moisture contained in the air can be performed by various methods.

The humidity of the air measured by the humidity sensor, that is, the measured humidity, may be determined according to a humidity measurement principle, and may be defined as relative humidity.

The relative humidity is expressed in % or %RH and is defined as (current amount of water vapor)/saturated water vapor at current temperature)×100.

And the set humidity range may be defined as the set humidity ± Δ humidity error.

Specifically, the set humidity may be set to 50%RH, and the Δ humidity error may be set to 15%RH.

Meanwhile, in the dehumidifying mode performing step (S20), the temperature of the air in some of the plurality of thermoelectric module units 100 is higher than the dew point based on the air flow direction of the cooling passage CF, so that the cooling function is performed, and the air in the rest It is possible to control the amount of air flow through the cooling flow path (CF) to perform the dehumidifying function as the temperature of the unit is lower than the dew point.

The air flow rate control may be performed by controlling a rotation speed of a fan that forms an air flow through the cooling passage CF.

Specifically, the flow amount of air in the dehumidifying mode performing step S20 may be controlled based on the air flow amount in the cooling mode performing step S10, specifically, the rotation speed of the fan.

For example, the flow rate of air through the cooling flow path CF in the dehumidifying mode performing step S20 is 70% to 90% of the air flow rate through the cooling flow path CF in the cooling mode performing step S10 . It is preferable to be

If the flow rate of the air is greater than 90%, the air flow in the second heat exchange unit 130 is fast, so the dehumidifying effect cannot be achieved. There is a problem in that the flow of air through the air conditioner is lowered, which prevents the cooling function from being performed.

According to the actual experiment, as shown in Fig. 25, it was confirmed that the ambient temperature can be controlled in a state close to the set temperature and set humidity.

For specific experimental conditions, the cooling temperature range was set to 25±2° C., and the set humidity range was set to 50±15% RH using the thermoelectric air conditioner shown in FIGS. 1 to 23c.

As a result, the average of the measured temperature measured by the temperature sensor was 24.7 ℃, the average of the measured humidity measured by the humidity sensor was 53.6 %RH, and the measured temperature and the measured humidity were 25±2 ℃ and 50±15%RH. was confirmed to be maintained.

Meanwhile, in the dehumidification mode performing step (S20), the temperature of the air is measured by a temperature sensor during the execution, and the measured temperature is input in the preset cooling temperature range (preset set temperature ( _TS ) + error range (ΔT) )), the dehumidifying function may be stopped and the cooling mode performing step (S10) may be performed.

And after the cooling mode performing step (S10) is performed, the dehumidifying mode performing step (S20) may be performed again.

Meanwhile, in order to perform the dehumidification mode performing step (S20), when the measured temperature is within the set cooling temperature range and the specific humidity is also within the set humidity range, the stopping step of stopping the dehumidifying mode performing step (S20) may be performed. .

At this time, the temperature and humidity are measured even when the dehumidifying mode performing step (S20) is stopped, and if the measured temperature is greater than the set cooling temperature range, after the cooling mode performing step (S10) is performed, the dehumidifying mode performing step (S20) is performed again can be done

If the measured temperature measured at the time of stopping the dehumidification mode performing step S20 is within the set cooling temperature range, and the measured humidity is greater than the set humidity range, the dehumidifying mode performing step S20 is performed again.

Meanwhile, the measurement temperature of the air may be excessively lower than the set temperature ( _TS ) by performing the dehumidifying mode performing step (S20), which needs to be corrected.

At this time, if the measured temperature is smaller than the set temperature ( _TS ), the dehumidification mode performing step (S20) is stopped and the direction of the current applied to the thermoelectric module of the thermoelectric module unit 100 is reversed to change the functions of the heat dissipation part and the heat absorbing part to change the second By dissipating heat from the heat exchange unit 130 and increasing the temperature of the air flowing through the second heat exchange unit 130 , it is possible to correct that the measured temperature of the air is excessively lower than the set temperature T _S .

Meanwhile, the steps described above may be performed depending on whether the measured temperature is within the set cooling temperature range by the temperature correction.

Specifically, if the measured temperature is greater than the set cooling temperature range, after the cooling mode performing step (S10) is performed, the dehumidifying mode performing step (S20) may be performed again.

And if the measured temperature is within the set cooling temperature range, if the measured humidity is greater than the set humidity range, the dehumidification mode performing step (S20) is performed again.

When the measured measured temperature is within the set cooling temperature range and the measured humidity is within the set humidity range, the above-described stopping step may be performed.

Meanwhile, the refrigerant for cooling the first heat exchange unit 120 of the thermoelectric module unit 100 sequentially flows through the first heat exchange unit 120 of each thermoelectric module unit 100, and air through the cooling passage CF. The flow direction of is preferably opposite to the flow direction of the refrigerant, as shown in FIG. 24 .

That is, when the refrigerant flow direction is set opposite to the air flow direction, the temperature of the refrigerant at the suction side from which air is sucked is maintained higher than the temperature of the refrigerant at the discharge side from which the air is discharged, so that the temperature of the air at the suction side and the air at the discharge side are maintained. temperature variation is maximized.

And when the temperature deviation is maximized as described above, the temperature of the air flowing through a predetermined number (for example, ①, ②, ③) of the second heat exchange parts 130 from the suction side among the plurality of second heat exchange parts 130 . The temperature above the dew point is maintained, and the temperature of the air flowing through the remaining number (for example, ④) of the second heat exchanger 130 is maintained below the dew point, so that some (for example, ① , ②, ③) of the second heat exchange unit 130 performs a cooling function and the remaining (for example, ④) second heat exchange unit performs a dehumidifying function, so that cooling and dehumidification can be efficiently performed.

Meanwhile, the refrigerant is sucked from the second space and flows around the first heat exchange unit 120 of the thermoelectric module unit 100 to cool the first heat exchange unit 120 of the thermoelectric module unit 100 and then to the second space. The exhausted air may be used.

In addition, the refrigerant may be configured to flow along a refrigerant passage formed in the first heat exchange unit 120 .

That is, the cooling of the first heat exchange unit 120 may be performed by various methods such as air cooling or water cooling.

Since the above has only been described with respect to some of the preferred embodiments that can be implemented by the present invention, as noted, the scope of the present invention should not be construed as being limited to the above embodiments, and It will be said that the technical idea and the technical idea accompanying the fundamental are all included in the scope of the present invention.
