Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in 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 invention and are not intended to limit the invention.
The principles and construction of the present invention will be described in detail below with reference to the drawings and examples.
As shown in fig. 1, the present invention provides a method for controlling a drain pump of a water pan of an air conditioner, comprising the steps of: when the air conditioner operates in a refrigeration mode, monitoring the indoor temperature and the operating frequency of the compressor, judging a preset temperature interval where the current indoor temperature is located, controlling the drainage water pump to adjust the rotating speed to the preset rotating speed corresponding to the preset temperature interval corresponding to the current operating frequency of the compressor, and automatically increasing the rotating speed of the drainage water pump due to more accumulated water in the water receiving tray due to faster generation speed of the condensed water when the indoor temperature is in different temperature intervals because the indoor temperature is different, so that the full water protection caused by insufficient rotating speed of the water pump is avoided, the evaporator is immersed in the accumulated water in the water receiving tray, the refrigeration capacity is not fully exerted, and even the condensation problem caused by lower temperature of the indoor evaporator is generated; when the indoor temperature is close to the set temperature state, the rotating speed of the drainage water pump can be reduced, the energy consumption loss of the water pump caused by the small water quantity of the water receiving tray is solved, and meanwhile, the indoor noise can also be reduced.
The water pump for water drainage adjusts the rotating speed to the preset rotating speed corresponding to the preset temperature interval corresponding to the operating frequency of the compressor, and the preset rotating speed comprises the following steps: and judging a preset frequency interval in which the current operating frequency of the compressor is positioned, wherein the preset revolutions corresponding to preset temperature intervals in different preset frequency intervals are different or the same, and controlling the rotating speed of the drainage water pump according to the corresponding preset rotating speed. Make the water pump rotational speed relevant with the operating frequency of compressor, the speed that the indoor set produced the comdenstion water when the operating frequency of compressor is higher can accelerate, sets up to the difference through presetting the revolution that presets that temperature interval corresponds in presetting the frequency interval with the difference, makes the control of drainage water pump more accurate, improves drainage efficiency, reduces the energy consumption loss of water pump.
When the air conditioner operates in the heating mode, the drainage water pump is closed, and energy consumption waste is avoided.
After the air conditioner starts a refrigeration mode, the air conditioner operates for a preset time and then monitors the indoor temperature and the operating frequency of the compressor, so that the air conditioner is ensured to be in a stable operation state. In the preset time, the rotating speed of the drainage water pump is adjusted to the maximum preset rotating speed for operation, and the temperature difference between the indoor temperature and the set temperature is usually the maximum when the refrigeration mode is just started, so that the generation speed of the condensed water is also the maximum.
The preset frequency interval comprises a first frequency interval, a second frequency interval and a third frequency interval, wherein the frequencies of the first frequency interval, the second frequency interval and the third frequency interval are increased step by step. The preset temperature interval comprises a first temperature interval, a second temperature interval and a third temperature interval, wherein the temperatures of the first temperature interval, the second temperature interval and the third temperature interval are gradually increased. And if the current operating frequency of the compressor is in the first frequency interval, the preset rotating speeds corresponding to the second temperature interval and the third temperature interval are the same. And if the current operating frequency of the compressor is in a second frequency interval or a third frequency interval, the preset rotating speeds corresponding to the first temperature interval, the second temperature interval and the third temperature interval are the same and are increased step by step. The rotating speed of the water pump is related to the operating frequency of the compressor at the same time, and the speed of the indoor unit for generating condensed water is increased when the operating frequency of the compressor is high.

And if the current running frequency F of the compressor is greater than or equal to fb, judging that the current refrigerating output of the internal machine is larger, increasing the dehumidification amount and further detecting the indoor temperature.
If the indoor temperature tb is less than or equal to T, the indoor humidity is higher, more condensed water is generated, and the drainage water pump continuously operates according to the maximum rotating speed R max;
if the indoor temperature ta is less than or equal to T and less than tb, the indoor humidity is relatively high, the generated condensed water is relatively more, and the drainage water pump continuously operates according to the intermediate rotating speed R = R mid;
if the indoor temperature T is less than ta, the indoor humidity is relatively low, the generated condensed water is relatively less, and the drainage water pump continuously operates according to the lowest rotating speed R = R min.
If the current operation frequency F of the compressor is larger than or equal to fa and smaller than or equal to fb (about the middle value of the current machine type operation frequency), it indicates that the current indoor unit refrigerating output is relatively large, the dehumidification amount is large, and further indoor temperature detection is performed.
If the indoor temperature tb is less than or equal to T, the indoor humidity is higher, more condensed water is generated, and the drainage water pump continuously operates according to the maximum rotating speed R max;
if the indoor temperature ta is less than or equal to T and less than tb, the indoor humidity is relatively high, the generated condensed water is relatively more, and the drainage water pump continuously operates according to the intermediate rotating speed R = R mid;
if the indoor temperature T is less than ta, the indoor humidity is relatively low, the generated condensed water is relatively less, and the drainage water pump continuously operates according to the lowest rotating speed R = R min.
If the current operation frequency F of the compressor is less than fa (the current machine type operation frequency is about a low-frequency value), the current internal machine refrigerating output is relatively large, the dehumidification amount is large, and the indoor temperature is further detected.
If the indoor temperature tb is less than or equal to T, the indoor humidity is higher, but the generated condensed water is relatively more, and the drainage water pump continuously operates according to the intermediate rotating speed R mid;
if the indoor temperature ta is less than or equal to T and less than tb, the indoor humidity is judged to be relatively high, more condensate water is generated, and the drainage water pump keeps the continuous operation of the middle rotating speed R = R mid;
and if the indoor temperature T is less than ta, judging that the indoor humidity is relatively low, generating relatively less condensed water, and continuously operating the drainage water pump according to the lowest rotating speed R = R min.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
