Description

{ A control method for cave winds in window air conditioners }

The present invention relates to a method for controlling cave wind in a window type air conditioner, wherein temperature and humidity are controlled using an integrated temperature and humidity sensor to provide a feeling of being in a cave.

In general, an air conditioner has a refrigeration cycle device composed of a compressor, a condenser, a capillary tube, a heat exchanger, etc., and appropriately discharges the cold air formed in the evaporator and the warmth generated in the condenser according to the indoor conditions to improve the indoor atmosphere. It is a device that keeps you comfortable.

Air conditioners can be divided into window type air conditioners and separate type air conditioners according to the installation method. A window type air conditioner is equipped with a refrigeration cycle device in one casing and installed on a window, while a separate type air conditioner is divided into an indoor and an outdoor unit, and an indoor heat exchanger is installed in the indoor unit, and an outdoor heat exchanger and a compressor are installed in the outdoor unit. It is installed outdoors [Patent Document 1]. In particular, the window type air conditioner has both an indoor heat exchanger and an outdoor heat exchanger in the body, but separates them by installing a diaphragm panel in the middle.

In particular, the window type air conditioner has a structure in which the indoor unit (evaporator) and the outdoor unit (condenser) are integrally built into the case, and a window frame installation frame installed on the window is separately included, so that users who are not professional engineers can easily install it directly. it is possible In addition, since the rear surface of the air conditioner facing the outdoors does not protrude through the outer wall, when installed on the double window frame, there is an advantage in that the outer window can be closed when not in use.

On the other hand, the evaporator and condenser configured as an air conditioner may be used as a dehumidifying function. That is, when cooling is performed by driving the evaporator and condenser in the air conditioner, the condensation point of moisture is lowered and dehumidification is automatically performed.

Therefore, a technology for dehumidifying using an evaporator and a condenser of an air conditioner has been proposed [Patent Documents 2 and 3]. However, the prior art is configured to individually control temperature and humidity. That is, the user needs to adjust the room temperature for cooling and, if the humidity is too high, drive the dehumidification function to lower the humidity.

Therefore, in the prior art, by individually controlling the cooling temperature and humidity, there is a problem in that energy efficiency is lowered because the user is inconvenienced and unnecessary air conditioners are driven.

Hereinafter, specific details for the implementation of the present invention will be described according to the drawings.

In addition, in explaining the present invention, the same reference numerals are assigned to the same parts, and the repeated explanation thereof is omitted.

First, the configuration of a window type air conditioner according to an embodiment of the present invention will be briefly described with reference to FIGS. 1 to 3 .

As shown in FIGS. 1 to 3, the window type air conditioner 1000 according to an embodiment of the present invention includes a case 100, an evaporator 200 installed in the case 100 and installed indoors, and a case 100 ), a cylindrical evaporator fan 700 disposed in and installed adjacent to the evaporator, a condenser 300 installed in the case 100 and installed standing on the outdoor side, and a front part of the condenser 300 in the case 100 It is disposed on and consists of a cylindrical condenser fan 600 installed next to the condenser 300.

In this case, as the condenser fan 600 operates, outdoor air is introduced through the second suction part 160 and discharged through the second discharge part 170 to cool the condenser 300, and the evaporator fan ( 700), the indoor air is introduced through the first suction part 140 and discharged through the first discharge part 150, thereby cooling the inside of the case 100.

In particular, as shown in FIG. 3, when viewed from a plane, the condenser 300 and the condenser fan 600, and the evaporator 200 and the evaporator fan 700 are separated by a partition wall 900, and the partition wall 900 and Between the sides of the condenser fan 600, a guide air passage 910 including an inlet 911 and an outlet 912 is formed to guide air introduced from the outdoors through the condenser 300 back to the outdoors. has been

In addition, the window type air conditioner 1000 according to the present invention is configured to include a control device 800 installed on the partition wall 900 in the receiving space 670 on the opposite side of the condenser fan 600 around the partition wall 900. .

In addition, a guide air path 910 is formed between the partition wall 900 and the side surface of the condenser fan 600 to guide air introduced from the outdoors through the condenser 300 back to the outdoors. The heat dissipation member 500 attached to the control device 800 is inserted through the partition wall 900 facing the side, and one side is exposed to the guide air passage 910. Through this, heat generated from the control device 800 while the air conditioner is running due to the air flow generated when the condenser fan 600 rotates is not stagnant in the accommodation space 670 and is discharged to the outside through the heat radiation member 500. can
In addition, the inside of the tubes of the evaporator 200 and the condenser 300 are filled with refrigerant. The refrigerant is compressed to a high pressure by a compressor (not shown), the compressed refrigerant is condensed by releasing heat in the condenser 300, and the condensed refrigerant is expanded through an expansion valve (not shown) and moved to the surroundings in the evaporator 200. It absorbs heat from the air and cools it. That is, the refrigerant is circulated and the air conditioner is driven according to the control of the compressor.

Meanwhile, a temperature and humidity sensor 400 for simultaneously measuring temperature and humidity is provided on the side of the evaporator fan 700 .

Next, a cave wind control method of a window type air conditioner according to a first embodiment of the present invention will be described with reference to FIGS. 4 to 6 . A cave wind control method of a window type air conditioner according to an embodiment of the present invention is performed by the control device 800 .

As shown in FIGS. 4 and 5 , first, the control device 800 controls the compressor to be operated at the maximum stage for a first predetermined operating time (S10). That is, an operation signal is output to the compressor inverter.

Preferably, the first operating time is set to 10 minutes. This step is for stabilizing the compressor. Therefore, it is operated at the maximum step, preferably, at 5 steps.

Meanwhile, when the cave wind type driving control method starts, the control device 800 displays a guide indicating that the cave wind driving method is displayed on a panel or the like (not shown).

Next, the control device 800 operates the compressor according to the temperature difference between the measured temperature and the first target temperature (S21), and continues to operate until the measured temperature reaches the first target temperature (S22).

The measured temperature is the temperature measured by the temperature and humidity sensor 400 and refers to the current temperature.

The first target temperature and the second target temperature are predetermined temperatures for cave wind. The first target temperature is set higher than the second target temperature. That is, the first and second target temperatures indicate a temperature range for cave wind. Preferably, the first target temperature is set to 24 degrees and the second target temperature is set to 22 degrees.

Preferably, the control device 800 adjusts the operating stage of the compressor according to the magnitude of the temperature difference between the measured temperature and the first target temperature.

The operating stage of the compressor or the inverter of the compressor is divided into a plurality of stages according to the speed of the inverter. That is, the higher the speed of the inverter, the higher the level. Preferably, the operation step is divided into 5 steps. Step 1 has the lowest inverter speed, and step 5 has the highest inverter speed.

As shown in FIG. 6, as the temperature difference increases, control is performed to operate at a higher operating level. In the example of FIG. 6 , when the temperature difference between the measured temperature and the first target temperature is 2 degrees or more, the driving step is performed at the highest step, that is, step 5. In addition, if the temperature difference is 0.5 degree difference, the operation step is set to step 2 and controlled to operate.

On the other hand, preferably, when the driving step is changed, the control device 800 operates the driving step for a predetermined minimum driving time. This is to avoid frequent changes to the operating phase as the temperature changes.

For example, if the minimum driving time is set to 10 minutes, and the driving level descends from level 5 to level 4, driving continues at level 4 for at least 10 minutes. And then, the temperature difference is calculated, the driving step is set according to the calculated temperature difference, and if the driving step is different from the current driving step, the driving step is changed.

In addition, the minimum operating time is set differently by distinguishing between a case in which the temperature (or operation stage) rises and a case in which the temperature decreases. Preferably, the minimum driving time when descending (hereinafter, the minimum driving time when descending) is set to be greater than the minimum driving time when ascending (hereinafter, minimum driving time when ascending).

If the temperature rises even though the compressor is operated (if the operation level needs to be increased), it means that the temperature cannot be lowered to the current operation level, so more powerful cooling is required. Therefore, the temperature is controlled to be lowered by increasing the minimum operating time.

Next, the controller 800 compares the measured humidity with a predetermined target humidity (S31). If the measured humidity is not higher than the target humidity, it ends.

The measured humidity is the humidity measured by the temperature and humidity sensor 400 and represents the current humidity. The target humidity is a humidity determined in advance, and is a humidity for cave wind. Preferably, the target humidity is set to 45 to 50 degrees.

Next, if the measured humidity is greater than the target humidity, the compressor or compressor inverter is controlled to operate (S32). That is, the operation of the compressor is extended to lower the humidity.

At this time, preferably, the operation is performed by setting the operation level to the lowest level. In this case, since the temperature has already been lowered within the temperature range of the cave wind, rather than lowering the temperature, the operating time should be increased to lower the humidity. Therefore, the operation time is increased by setting the operation level to the lowest level so that the temperature does not drop rapidly.

This operation control continues until the measured humidity reaches the target humidity (S33). That is, if the measured humidity is greater than the target humidity, operation continues. If the measured humidity reaches the target humidity, the operation of the compressor is stopped and terminated (S35).

At this time, in particular, the measurement is repeated until the temperature reaches the second target temperature (S34).

If the measured humidity does not reach the target humidity and the measured temperature reaches the second target temperature (S33 and S34), the compressor inverter is stopped (S41). Then, the compressor is controlled to stop for a predetermined stop time (S42).

Preferably, the stop time is set to 3 minutes.

After the stop time has elapsed, the current temperature is measured and the measured temperature is compared with the second target temperature (S43). If the measured temperature is not higher than the second target temperature, the operation of the compressor continues to be stopped. That is, the compressor inverter is controlled to stop until the measured temperature becomes higher than the second target temperature.

Next, if the measured temperature is higher than the second target temperature, it returns to the step of extending the operation of the compressor (S32), and the step is executed again from that step.

Next, a cave wind control method of a window type air conditioner according to a second embodiment of the present invention will be described. The second embodiment of the present invention is the same as the first embodiment described above, but there is a difference in the step of extending the compressor inverter (S32). Hereinafter, only differences from the first embodiment will be described. Parts not described below refer to the description of the first embodiment.

The inverter of the compressor can be controlled to further subdivide the operation phase of the inverter in the extension phase. That is, in the extended step for humidity control, the operation step is configured to operate in at least two operating steps such as step 2 and step 1, or to control by further subdividing the minimum step, that is, step 1. For example, it may be subdivided into 1 step, 0.8 step, 0.6 step, 0.4 step, and the like. It is subdivided according to the speed control of the inverter.

At this time, the operation step in the extension step is adjusted according to the size of the humidity difference.

Preferably, the control is performed to operate in a lower detail step as the difference in humidity increases. For example, if the difference in humidity is 10%, it operates in step 1, if the difference in humidity is 5%, it is operated in step 0.8, and if the difference in humidity is 3%, it operates in step 0.6.

That is, when the difference in humidity is large, the operation is performed at a low speed so as not to drop the temperature as much as possible. Through this, the operation time is increased and the humidity is controlled to be lowered more.

In the above, the invention made by the present inventors has been specifically described according to examples, but the present invention is not limited to the examples, and various changes are possible without departing from the gist of the invention.
