Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 to 3 show a preferred embodiment of the present invention.
In the existing air conditioner, in a cooling mode, indoor wall surfaces are easy to generate condensation due to heat exchange airflow led out from an air outlet of the air conditioner. Especially, when the heat exchange airflow blown out from the air outlet of the air conditioner is directly guided to the indoor wall surface, dew is easily formed on the indoor wall surface due to temperature reduction. The condensation prevention control method is used for solving the problem of condensation generated on the indoor wall surface. The control method is specifically described below, and for convenience of explanation, the cabinet air conditioner with the upper air outlet and the lower air outlet located below the upper air outlet is exemplified below, it should be noted that the use scenario of the control method in the present invention is not limited by the type of the indoor air conditioner and the number and arrangement position of the air outlets, and any air conditioner that is prone to generate condensation on the indoor wall surface (the wall surface may be an indoor vertically arranged wall, a horizontally arranged floor, or a horizontally arranged ceiling, and the like, and the wall surface is exemplified below as the floor) may perform condensation removal processing by using the control method.
The air conditioner in this embodiment is including setting up in indoor machine of air conditioner, and the machine specifically can be cabinet air conditioner in the air conditioner, and it includes upper air outlet and the lower air outlet that is located the upper air outlet below, and lower air outlet sets up in the below of air conditioner, and the heat transfer air current that the air outlet blew off down can lead to ground for when the air conditioner is the refrigeration mode, indoor ground easily produces the condensation, arouses user complaint easily or produces the user and slips the accident.
The control method comprises the following steps:
s102: in a refrigeration mode, acquiring the rotating speed of a fan which sprays airflow out of a downward air outlet of an indoor unit;
s104: when the rotating speed of the fan is within the interval of [490rpm, 670rpm ], acquiring the condensation state of the ground, and judging whether a condensation removing signal is generated according to the condensation state;
s106: and after the condensation removing signal is generated, the air outlet temperature of the lower air outlet of the indoor unit is increased and lasts for a first preset time.
The air conditioner generally has several gears of strong wind, high wind, middle wind, low wind and mute wind. Specifically, when the air conditioner is in a strong wind state, the rotating speed of the fan is about 780 rpm; when the air conditioner is in a high wind state, the rotating speed of the fan is about 680 rpm; when the air conditioner is in a wind stroke state, the rotating speed of the fan is about 620 rpm; when the air conditioner is in a low wind state, the rotating speed of the fan is about 540 rpm; when the air conditioner is in a mute wind state, the rotating speed of the fan is about 400 rpm. When the air conditioner has the gear, reasoning and experimental demonstration show that more condensation is easy to generate when the air conditioner is in a stroke state and a low wind state; when the air conditioner is in a breeze state, less condensation is generated; when the air conditioner is in a high wind state and a strong wind state, most of generated condensation is naturally dried. I.e. only in stroke and low wind conditions, a special dewing treatment is required. Therefore, in step S102, before the anti-condensation process is performed, the rotation speed of the fan is obtained, so that the air conditioner is not unnecessarily operated when the rotation speed of the fan is too high and the anti-condensation process is not particularly performed.
In one embodiment, the air outlet gear of the air conditioner can be acquired, and when the air outlet gear is a medium wind gear and a low wind gear, subsequent condensation removing treatment is carried out. However, the number of each air outlet gear and the actual rotating speed of each air outlet gear are different due to different types of each air conditioner. Therefore, the air conditioner is better adapted to various types of air conditioners. In another embodiment, as in step S104, the rotation speed of the fan that ejects the airflow out of the downward outlet of the indoor unit in the cooling mode may be obtained, and when the rotation speed of the fan is within the [490rpm, 670rpm ] interval, the air conditioner is determined as the default and the condensation removing process is required, and when the rotation speed of the fan is not within the above interval, the subsequent condensation removing step may not be performed.
When the condensation removing treatment is carried out, the condensation state of the ground (the ground which is in contact with the airflow blown out from the lower air outlet) needs to be acquired firstly, and when the condensation amount is found to be large, a condensation removing signal is generated; when the amount of dew was found to be small, no signal for dew removal was generated. In step S106, after the condensation removing signal is generated, the temperature of the heat exchange airflow guided out from the lower air outlet may be continuously increased for a first preset time (that is, the temperature of the heat exchange airflow guided out from the lower air outlet is always maintained at the increased temperature within the first preset time, and a value interval of the first preset time may be [1h, 2.5h ], for example, 1h, 2h, or 2.5h), so that condensation removing processing is performed. When the heat exchange airflow rises, the rising amount is small, and the generation of condensation can be reduced, so that the condensation can be removed (when the generated condensation is small, the generated condensation is continuously air-dried, and finally the total condensation is reduced); when the rising amount is large, the air drying effect can be enhanced, thereby realizing the condensation removal.
Because the rotation speed of the fans of each air conditioner does not correspond to the generated air volume or air speed (that is, although the rotation speed of the fan of the first air conditioner is higher than that of the fan of the second air conditioner, the air volume or air speed generated by the second fan is higher than that of the first fan due to different structures of the fan blades), when the situation occurs, the method for monitoring the rotation speed of the fans in the control method is not applicable any more, in one embodiment, the air volume or air speed generated by the fans can be monitored, in another embodiment, the step S102 can be omitted, and the indoor condensation state can be directly obtained. Namely, the anti-condensation control method can also be as follows:
s302: in a refrigeration mode, acquiring a condensation state of the indoor wall surface, and judging whether a condensation removing signal is generated according to the condensation state;
s304: and after the condensation removing signal is generated, the air outlet temperature of the air outlet of the indoor unit is increased and lasts for a first preset time.
In step S104, the condensation state of the indoor floor may be directly obtained or indirectly obtained. When the obtaining is indirect, in an embodiment, the step of obtaining a condensation state of the ground in the room, and determining whether to generate a condensation removing signal according to the condensation state may include: the method comprises the steps of timing the discharge time of the heat exchange airflow when the lower air outlet starts to discharge the heat exchange airflow, and generating a condensation removing signal when the discharge time of the heat exchange airflow is larger than a second preset time (the value interval of the second preset time can be [1h, 2h ], such as 1h, 1.5h or 2 h). In other words, in the above steps, the condensation condition of the indoor floor is indirectly obtained by monitoring the air outlet time of the lower air outlet. When the air outlet time is shorter than the second preset time, the condensation amount of the default indoor floor is less, and potential safety hazards do not exist. When the air outlet time is longer than the second preset time, the condensation amount of the default indoor floor is larger, and condensation removing treatment is needed.
Besides indirectly acquiring the condensation state of the indoor ground, the condensation state of the ground can be directly sensed by arranging a sensor. Namely, the step of acquiring the condensation state of the indoor ground comprises the following steps: the condensation state of the ground is sensed by a sensor. In particular, the sensor may be an infrared sensor.
In step S106, various means are used to increase the outlet air temperature at the lower outlet of the indoor unit. In one embodiment, the outlet air temperature can be increased by reducing the frequency of the compressor of the air conditioner. When the frequency of the compressor is lowered, the frequency may be lowered by a fixed value, for example 10 hz or 15 hz. The compressor frequency may also be reduced to a fixed proportion of the original frequency, for example, the compressor frequency may be reduced to five or six of the original frequency. Regardless of the manner in which the compressor frequency is reduced, it is desirable to have the compressor frequency be greater than 10 hz for good compressor operation.
When the rotating speed of the motor rises, the air outlet of the lower air outlet is large, the air drying effect is strong, so the air outlet temperature can be properly lowered, and the reduction frequency of the compressor can be properly reduced. When the rotating speed of the fan is within the interval [490rpm, 670rpm ], the air conditioner may have a plurality of air outlet gears, but the specific rotating speed of the fan at each air outlet gear cannot be determined because the specification of each air conditioner is different. Therefore, in one embodiment, when the rotation speed of the fan is within the [490rpm, 590rpm ] range, the default fan is in the low wind gear, and the outlet air temperature can be raised by reducing the frequency of the compressor of the air conditioner to fifty percent of the original frequency. When the rotating speed of the fan is within the interval of [590rpm, 670rpm ], the default fan is in a middle wind gear position, and the air outlet temperature can be increased by reducing the frequency of the compressor of the air conditioner to sixty percent of the original frequency.
In another embodiment, the air outlet temperature can be increased by increasing the rotating speed of a fan which sprays airflow out of the lower air outlet. For example, the rotation speed of the fan is increased by 20rpm and 40 rpm. Specifically, the rotating speed increasing value can be larger when the original rotating speed of the fan is smaller, and the rotating speed increasing value is smaller when the original rotating speed of the fan is larger. For example, when the original rotation speed of the fan is within the [490rpm, 590rpm ], the rotation speed of the fan may be increased by 40rpm in order to increase the outlet air temperature of the lower outlet. When the original rotating speed of the fan is within the interval of [590rpm, 670rpm ], the rotating speed of the fan can be increased by 20rpm in order to increase the outlet air temperature of the lower air outlet.
In another embodiment, the frequency of the compressor of the air conditioner may be reduced, and the rotation speed of the fan for blowing the airflow out of the lower outlet may be increased to raise the outlet air temperature.
In another embodiment, a heating component may be further disposed at the lower air outlet of the air conditioner to heat the heat exchange airflow discharged from the lower air outlet.
In order to accelerate the efficiency of removing the condensation, when the air outlet temperature of the lower air outlet of the indoor unit is raised after the condensation removing signal is generated, in an embodiment, the air outlet temperature of the lower air outlet of the indoor unit can be raised to be higher than the indoor dew point temperature. After the air outlet temperature of the lower air outlet rises, the heat exchange airflow guided out by the lower air outlet cannot increase condensation on the ground, and the remaining condensation is naturally air-dried, so that the purpose of removing the condensation is achieved. Particularly, in order to further improve the condensation removing efficiency, the air outlet temperature can be increased to the indoor environment temperature, so that the condensation is not increased, and the evaporation rate of the generated condensation can be increased.
When the rotating speed of the motor rises, the air outlet of the lower air outlet is large, the air drying effect is strong, so the air outlet temperature can be properly lowered, and the reduction frequency of the compressor can be properly reduced. When the rotating speed of the fan is within the interval [490rpm, 670rpm ], the air conditioner may have a plurality of air outlet gears, but the specific rotating speed of the fan at each air outlet gear cannot be determined because the specification of each air conditioner is different. Therefore, in one embodiment, when the rotation speed of the fan is within the [490rpm, 590rpm ] range, the default fan is in the low wind gear, and the outlet air temperature can be raised by reducing the frequency of the compressor of the air conditioner to fifty percent of the original frequency. When the rotating speed of the fan is within the interval of [590rpm, 670rpm ], the default fan is in a middle wind gear position, and the air outlet temperature can be increased by reducing the frequency of the compressor of the air conditioner to sixty percent of the original frequency.
As shown in fig. 2, the present embodiment exemplarily shows an optional flow of the anti-condensation control method for the air conditioner:
s204: and the air conditioner is positioned in the refrigeration mode and starts to operate, and the air outlet time is timed.
S206: and comparing the timing time with a second preset time.
S208: and when the timing time is greater than the second preset time, acquiring the rotating speed of the fan.
S210: when the rotating speed of the fan is within the interval of [490rpm, 590rpm ], the frequency of the compressor is reduced to fifty percent of the original frequency, and the rotating speed of the fan is increased by 40rpm so as to raise the outlet air temperature of the lower air outlet.
S212: when the rotating speed of the fan is within the interval of [590rpm, 670rpm ], the frequency of the compressor is reduced to sixty percent of the original frequency, and the rotating speed of the fan is increased by 20rpm so as to increase the air outlet temperature of the lower air outlet.
S214: and after the lifting effect of the air outlet temperature is kept and the first preset time is continued, the normal operation of the air conditioner under the original refrigeration mode is recovered.
The present invention also provides an air-conditioning indoor unit for performing a condensation removal process by using the condensation prevention control method in any of the above embodiments, where the air-conditioning indoor unit may specifically be a cabinet air-conditioner, and includes an upper air outlet, a lower air outlet, and a controller. The lower air outlet is arranged below the upper air outlet. The controller includes a memory and a processor, the memory storing a computer program, the computer program when executed by the processor implementing the anti-condensation control method according to any one of the above. In order to be able to detect the condensation state of the floor, in one embodiment, the indoor unit of the air conditioner further includes a sensor for sensing the condensation state of the floor in the room.
In one case, the heat exchange airflow from the lower outlet may be directed toward the user's legs, resulting in overcooling of the user's legs. In order to solve the defects, the indoor unit of the air conditioner can further comprise a sensor for sensing position information of a human body, the sensor is electrically connected with the controller, when the sensor detects that the human body is located near the lower air outlet, and heat exchange airflow blown out of the lower air outlet is directly blown to legs of the human body, the controller controls the heating element to heat the heat exchange airflow blown out of the lower air outlet, and the difference between the temperature of the heat exchange airflow led out of the lower air outlet and the indoor environment temperature is within the range of 2 ℃. The heating member has first heating power promptly, and when the heating member was under first heating power, the difference that the temperature of the heat transfer air current that lower air outlet was derived was heated to indoor ambient temperature by the heating member was within 2 degrees centigrade. When the sensor does not detect that the heat exchange airflow blown out from the lower air outlet is not directly guided to the human body, the controller can close the heating element.
Particularly, the heating member can also be used for removing the condensation, and when the air conditioning indoor set had the heating member, the controller can control the heating member and let the heating member heating when the condensation was removed in needs to make the air-out temperature of air outlet be higher than indoor dew point temperature down. The heating element has second heating power promptly, and when the heating element was under second heating power, the heating element was heated to the temperature that is higher than indoor dew point temperature by the temperature of the heat transfer air current that lower air outlet derived.
Because the vertical height of the upper air outlet of the cabinet air conditioner is higher than that of the lower air outlet, the temperature of the heat exchange airflow guided out by the lower air outlet is lower than that of the heat exchange airflow guided out by the upper air outlet, and the air outlet is uneven. In order to make the temperatures of the heat exchange air flows led out from the two air outlets consistent, in one embodiment, the indoor unit of the air conditioner further comprises a heating element, and the heating element is configured to heat the heat exchange air flow led out from the lower air outlet when being opened, so that the temperature of the heat exchange air flow led out from the upper air outlet is equal to the temperature of the heat exchange air flow led out from the lower air outlet. The temperature that the heating member produced is carried out real time control by the controller, nevertheless because the not enough of control accuracy, actually can make the heat transfer air current that lower air outlet derived and go up the air outlet and derive the temperature difference who divides heat transfer air current and be in 0.3 degrees centigrade scope. The heating member has third heating power promptly, and when the heating member was in under the third heating power, the temperature of the heat transfer air current that lower air outlet derived is heated by the heating member and is within 0.3 degrees centigrade with the difference of the temperature of the heat transfer air current that upper air outlet derived.
The heating member can set up in air outlet down for the heat transfer air current carries out the heat transfer with the heating member when exporting down the air outlet. In particular, the heating element may be mesh-shaped and arranged such that the heat-exchange air flow passes through the heating element and is directed out of the lower outlet. This increases the rate of heat transfer from the heat transfer gas stream to the heating element. Furthermore, when the heating element is in a net shape, the heating element can completely cover the lower air outlet, namely, the heat exchange air flow can be led out of the lower air outlet only by passing through the heating element.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
