At present, when indoor air circulates through an indoor unit due to the fact that the indoor ambient temperature and the temperature difference of the indoor unit of the air conditioner (the temperature difference between an indoor evaporator and the indoor ambient temperature, and the temperature difference between the vicinity of an air outlet of the indoor unit and the indoor ambient temperature) cause when the refrigerator operates in a refrigerating mode, a condensation prevention mode is set in the air conditioner to execute condensation prevention operation, but most of the air conditioners aimed at the indoor air conditioner do not have relative humidity sensors, the indoor relative humidity where the indoor unit of the air conditioner is located cannot be detected, so that the time selection for the condensation prevention operation entering in the prior art is not accurate, the good condensation prevention effect cannot be achieved, the normal operation of the air conditioner is influenced, and the user experience is reduced.
In view of the above problem, referring to fig. 1, an embodiment of the present application provides an air conditioner 01, where the air conditioner 01 includes: a relative humidity sensor 12 arranged on an indoor unit 11 of the air conditioner 01 and used for detecting the indoor relative humidity corresponding to the air conditioner, a first temperature sensor 15 arranged on or near an indoor evaporator 111 of the indoor unit 11 and used for measuring the saturation temperature of the indoor evaporator 111, a second temperature sensor 14 arranged on the indoor unit 11 and used for detecting the indoor temperature, an indoor fan 112 arranged in the indoor unit 11, and an air conditioner control device 13 capable of controlling the air conditioner according to the operation parameters (including data detected by various sensors) generated in the operation process of the air conditioner 01; the control device may be the main control board of the air conditioner 01 itself or a chip integrated on the main control board.
Based on the air conditioner, referring to fig. 2, an embodiment of the present application provides a control method of an air conditioner, which is specifically applied to a control device of the air conditioner, and the method includes steps 201 and 204:
201. when the air conditioner operates in a refrigerating mode, first operation parameters of the air conditioner are obtained.
Wherein the first operating parameter comprises: the first relative humidity of the indoor corresponding to the air conditioner and the rotating speed of an indoor fan of the air conditioner.
In the embodiment of the present application, the first operation parameter may be detected by a sensor provided on the air conditioner, or may be directly or indirectly obtained from operation data of the air conditioner itself. For example, as shown in fig. 1, the relative humidity sensor 12 in the room may detect the relative humidity in the room corresponding to the air conditioner, and when step 201 is executed, the control device of the air conditioner may obtain the current relative humidity data detected by the relative humidity sensor 12 from the relative humidity sensor 12 (the same applies to the subsequent relative humidity data), and use the current relative humidity data as the first relative humidity. The rotating speed of the indoor fan is driven by the electric energy supplied by the air conditioner to operate, so that the operating rotating speed of the indoor fan is in certain relation with the working voltage or the working current of the indoor fan, and the control device of the air conditioner can obtain the rotating speed of the indoor fan by acquiring the working voltage or the working current and other data of the indoor fan during the refrigerating operation.
202. And acquiring the accumulated running time and the continuous running time of a compressor of the air conditioner under the condition that the first running parameter meets the condensation condition.
Wherein the condensation conditions include: the first relative humidity is larger than the preset relative humidity, and the rotating speed of the indoor fan is smaller than the preset rotating speed. Illustratively, the preset relative humidity may be 70% (for example only, and other values are possible, as the case may be). Because the rotating speed of most air conditioner fans at present is divided into a plurality of wind speed gears (low gear, medium gear, high gear, mute gear, etc.) when a user remotely controls or controls an air conditioner, the rotating speed of an indoor fan of the air conditioner can be a specific wind speed gear, so the rotating speed of the indoor fan in the first operation parameter in the embodiment of the present application can be a certain wind speed gear (for example, low gear), and can also be an actual rotating speed value (for example, 500 r/min); the preset wind speed is the same (for example, medium gear or 1000r/min), and the units of the indoor fan and the preset wind speed are unified (both are wind speed gears or both are rotating speed values) when the rotating speed of the indoor fan is compared with the preset wind speed.
In the embodiment of the application, the condensation condition is used for determining that condensation has been generated or is about to be generated in the current refrigeration operation process of the air conditioner, and when the first operation parameter meets the condensation condition, the condensation has been generated or is about to be generated by the air conditioner; and when the first operation parameter does not meet the condensation condition, determining that the air conditioner does not exist or cannot generate condensation.
Specifically, when the first indoor relative humidity is greater than the first humidity threshold, it is indicated that the moisture content in the indoor air is high, and at this time, when the indoor air circularly flows through the indoor unit of the air conditioner, condensation is more easily generated indoors, so the condensation condition includes that the first relative humidity is greater than the preset relative humidity. When the indoor fan operates at a low rotating speed (the rotating speed of the indoor fan is lower than the preset rotating speed), the indoor air flows through the indoor unit at a low speed, the time of the indoor air staying in the indoor unit is long, moisture of the indoor air is condensed into dew on the indoor heat exchanger for a sufficient time, and therefore the dew condition needs to include that the rotating speed of the indoor fan is lower than the preset rotating speed. It should be noted that the first relative humidity equal to the predetermined relative humidity is a critical condition of condensation, so in the embodiment of the present application, the first relative humidity equal to the predetermined relative humidity may be a condensation condition or not, and is determined according to actual requirements, and is not limited herein. Furthermore, the rotation speed of the indoor fan equal to the preset rotation speed is also a critical condition of condensation, so that the rotation speed of the indoor fan equal to the preset rotation speed can be a condensation condition or a partial condensation condition.
In the embodiment of the present application, even in the case that the first operating parameter satisfies the condensation condition, it is required to satisfy the first operating parameter for a long enough time (the accumulated time of the intermittent satisfaction is long enough or the duration of the single satisfaction is long enough) to accumulate the condensation generated by the air conditioner. Therefore, if whether the anti-condensation operation is performed is determined only according to the first operating parameter, there is a case where the condensation amount of the air conditioner is so small that it naturally evaporates and does not fall down on the indoor floor or wall, and there is no need for anti-condensation or condensation removal at this time, so that it is necessary to acquire the cumulative operating time and the continuous operating time of the compressor of the air conditioner in the case where the first operating parameter satisfies the condensation condition after the first operating parameter is acquired.
Since the generation of condensation on the indoor evaporator is also related to the saturation temperature of the evaporator and the dew point temperature of the indoor air (critical temperature for characterizing the condensation of water vapor in the indoor air), the possibility of condensation exists only when the saturation temperature of the indoor evaporator is less than or equal to the dew point temperature. During the normal cooling of the air conditioner (the air conditioner is normal in performance, and is in the cooling mode in the case of indoor heat), the saturation temperature of the indoor evaporator is less than the dew point temperature. For example, when the indoor temperature Tn is 30 ℃, the saturation temperature Te of the indoor evaporator is 10 ℃, and the indoor relative humidity RHn is 60%, the indoor dew point temperature is Td:
Td＝RHn*100*(a+b*Tn)+c*Tn-d； (1)
wherein, a is 0.199, b is 0.0018, c is 0.85, d is 19.3, and a, b, c and d are all calculation parameters; substituting the values into equation (1) yields Td 0.6 × 100 (0.199+0.0018 × 30) +0.85 × 30-19.3 ═ 21.38(° c) > Te ═ 10 ℃.
It should be noted that the above formula (1) is an empirical formula obtained from actual data, and is only an example, and the calculation parameters in the actual formula may be changed, and is not limited specifically here.
So in step 201 and for obtaining the dew point temperature and the saturation temperature of the indoor evaporator.

Wherein, calculating the first dew point temperature in the room according to the first relative humidity and the first room temperature is required according to the above formula (1). It should be noted that, since the first saturation temperature equal to the first dew point temperature is a critical condition for condensation of the indoor evaporator, the first saturation temperature equal to the first dew point temperature may be a condensation condition or may not be a condensation condition, which is determined according to the actual condition.

As the difference between the second dew point temperature and the second saturation temperature is larger, more condensation is generated, and the condensation is easier to accumulate to cause dripping, and as long as the difference between the second dew point temperature and the second saturation temperature is within a preset range, less condensation is generated and the condensation is likely to volatilize naturally; under the condition, certain refrigeration efficiency can be ensured, and condensed water caused by condensation can be effectively prevented from dripping.
