The invention also provides a wall-mounted air conditioner, the wall-mounted air conditioner of the embodiment comprises an outdoor unit and the wall-mounted air conditioner indoor unit 100 of any embodiment, and the outdoor unit is communicated with the indoor unit 100.
In the air conditioner of the embodiment, the driving mechanism 130 and the purifying assembly 140 connected to the driving mechanism 130 are arranged in the indoor unit 100, and the purifying assembly 140 is driven by the driving mechanism 130 to move to the air inlet 121 to completely shield the air inlet 121, so that the air flow entering the indoor unit 100 is purified, and the air quality of the indoor environment is improved; in addition, when the quality of the ambient air is good and the air purification assembly 140 is not needed to be used for purifying the air, the purification assembly 140 can be driven by the driving mechanism 130 to be ejected upwards from the position covering the air inlet 121, so that the air inlet 121 is exposed, and the expansion of the functions and the flexibility of the use of the indoor unit 100 of the air conditioner are realized.
The purification assembly 140 is driven by the driving mechanism 130 to ascend and descend between the position of the upper part of the air inlet 121 at a predetermined distance and the position covering the air inlet 121, and when the purification function is not started, the purification assembly 150 is driven by the driving mechanism 130 to eject upwards from the air inlet 121 and is in a non-purification position; after the cleaning function is activated, the cleaning assembly 140 is driven by the driving mechanism 130 to cover the air inlet 121 and is located at a cleaning position to clean the air entering the indoor unit 100.
Because the purification component 140 is in purification position and non-purification position, the windage resistance that indoor set fan produced the air current is obviously different, after opening purification performance, the air current filters, inevitably leads to the heat transfer effect attenuation through the heat exchanger, appears the high load problem easily, can carry out corresponding control according to the operation mode of air conditioner, makes the air conditioner reduce the normal refrigeration or the influence of heating the function to the air conditioner when purifying.
In some alternative embodiments, the air conditioner includes a refrigeration system including a heat exchanger provided in the indoor unit 100 to exchange heat with air entering the indoor unit, a tube temperature sensor, and a controller. The tube temperature sensor is configured to detect a tube temperature of the heat exchanger of the indoor unit 100. The controller is configured to control the driving mechanism 130 to move the purifying assembly 140 to the purifying position after acquiring a trigger signal for the air conditioner to enter the purifying mode, so as to purify the air flow entering the indoor unit 100, and to perform feedback control on the refrigeration system according to the target pipe temperature in the purifying mode set by the pipe temperature of the heat exchanger of the indoor unit 100 when entering the purifying mode.
The refrigerating system also comprises an indoor unit fan, a compressor and a throttling device. The controller can also carry out corresponding control according to the operation mode of the air conditioner, so that the influence on the normal refrigeration or heating function of the air conditioner is reduced when the air conditioner is purified. The controller may be configured to: acquiring a tube temperature sensor to detect the tube temperature of a heat exchanger of the indoor unit in real time, and calculating the difference value between the tube temperature sensor and the target tube temperature; when the difference value is smaller than a preset first temperature difference threshold value, performing feedback control on a fan of the indoor unit according to the difference value; increasing the opening degree of a throttle device of the compression refrigeration cycle when the difference value is greater than or equal to the first temperature difference threshold value and less than the second temperature difference threshold value; and when the difference value is greater than or equal to a second temperature difference threshold value, reducing the frequency of the compressor of the compression refrigeration cycle, wherein the second temperature difference threshold value is greater than the first temperature difference threshold value.
For example, after the purification function is turned on, a target tube temperature of the heat exchanger tube temperature of the indoor unit 100 may be set, the heat exchanger tube temperature of the indoor unit 100 may be detected in real time, and the refrigeration system of the air conditioner may be feedback-controlled according to a temperature difference between the detected tube temperature and the target tube temperature.
The target tube temperature can be set according to the heat exchanger tube temperature of the indoor unit 100 when the indoor unit enters the purification mode, in this embodiment, the default position of the purification assembly 140 is a position where purification is not performed, when purification is started, the air conditioner is stable in a normal refrigeration or heating state, and at the moment, the heat exchanger tube temperature of the indoor unit 100 is the normal state temperature of the air conditioner in the current refrigeration mode or heating mode, so that the target tube temperature is set according to the heat exchanger tube temperature at the moment, and the influence on refrigeration and heating after the air conditioner is started and purified can be ensured to be small.
One specific control method is as follows:
when the air conditioner operates in a cooling mode, if the temperature of the heat exchanger tube after purification is lower than the target tube temperature and does not exceed a first temperature difference threshold (for example, 3 degrees), the fan of the indoor unit 100 can be subjected to feedback control according to the difference, and the lower the temperature of the heat exchanger tube is, the faster the fan rotating speed of the indoor unit 100 is. If the increase of the rotating speed of the fan of the indoor unit 100 cannot ensure that the temperature of the heat exchanger tube is maintained within the first temperature difference threshold value with the target tube temperature, the opening of a throttling device of the compression refrigeration cycle is increased, and if the temperature of the heat exchanger tube cannot be ensured to be maintained within the second temperature difference threshold value with the target tube temperature, the frequency of the compressor is reduced, so that the high load caused by the excessively low temperature of the heat exchanger of the indoor unit 100 is prevented.
When the air conditioner performs heating operation, if the temperature of the heat exchanger tube after purification is higher than the target tube temperature and does not exceed a first temperature difference threshold (for example, 3 degrees), the feedback control can be performed on the fan of the indoor unit 100 according to the difference, and the higher the temperature of the heat exchanger tube is, the faster the fan rotation speed of the indoor unit 100 is. If the increase of the rotating speed of the fan of the indoor unit 100 cannot ensure that the temperature of the heat exchanger tube is maintained within the first temperature difference threshold value from the target tube temperature, the opening of a throttling device of the compression refrigeration cycle is increased, and if the temperature of the heat exchanger tube cannot be ensured within the second temperature difference threshold value from the target tube temperature, the frequency of the compressor is reduced, so that the high load caused by the overhigh temperature of the heat exchanger of the indoor unit 100 is prevented.
The first temperature difference threshold and the second temperature difference threshold may be configured according to the specification and the use requirement of the heat exchanger of the indoor unit 100, for example, the first temperature difference threshold is set to plus or minus 3 degrees celsius, and the second temperature difference threshold is set to plus or minus 5 degrees celsius.
The wall-mounted air conditioning indoor unit 100 of this embodiment is provided with the purifying assembly 140 connected to the driving mechanism 130, and the purifying assembly 140 is driven by the driving mechanism 130 to move to the air inlet 121 to completely shield the air inlet 121, so as to purify the air flow entering the indoor unit 100 and improve the air quality of the indoor environment; in addition, when the quality of the ambient air is good and the air purification assembly 140 is not needed to be used for purifying the air, the purification assembly 140 can be driven by the driving mechanism 130 to be ejected upwards from the position covering the air inlet 121, so that the air inlet 121 is exposed, and the expansion of the functions and the flexibility of the use of the indoor unit 100 of the air conditioner are realized.
