Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments and accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
In order to find out whether the air conditioner fan motor rotates reversely in advance so as to repair and correct the problem unit as soon as possible, the inventor considers that the temperature can be detected by the existing temperature detection devices of the air conditioner indoor unit, such as an environment temperature sensing bulb, an air outlet temperature sensing bulb and the like, and then whether the fan motor rotates reversely is judged by comparing the temperature deviation.
Specifically, the present embodiment provides a method for determining whether a fan motor of an air conditioner is reversely rotated, which includes the following steps as shown in fig. 1:
step 101: acquiring the air inlet temperature of an air conditioner;
step 102: acquiring the indoor environment temperature or air supply temperature of an air conditioner;
step 103: and determining whether a fan motor of the air conditioner reversely rotates or not according to the difference between the inlet air temperature and the indoor environment temperature or the difference between the inlet air temperature and the air supply temperature.
In the above embodiment, whether the fan motor reverses is determined by the difference between the air inlet temperature of the air conditioner and the indoor environment temperature or the air supply temperature, so that the technical problem that whether the fan motor reverses cannot be effectively determined in the prior art is solved, the purpose of timely finding the reversal of the fan motor under the condition that hardware equipment is not additionally added is achieved, and the problem unit can be timely maintained.
In consideration of the difference in the structure and setting between the air conditioner using indoor air as the intake air and the air conditioner using outdoor air as the intake air, the adopted modes are different, and the indoor ambient temperature can be conveniently obtained for the air conditioner using indoor air as the intake air, and the supply air temperature can be conveniently obtained for the air conditioner using outdoor air as the intake air. Therefore, under the condition that the air conditioner is the air conditioner taking indoor air as air inlet, the indoor environment temperature where the air conditioner is located is obtained, and whether the fan motor of the air conditioner reverses or not is determined according to the difference value between the air inlet temperature and the indoor environment temperature. The air conditioner obtains the air supply temperature under the condition that the air conditioner uses outdoor air as the air supply, and determines whether the fan motor of the air conditioner reverses or not according to the difference between the air supply temperature and the air supply temperature.
Because the air conditioner takes indoor air as the inlet air, under normal conditions, the inlet air temperature detected by the environment temperature sensing bag is approximately equal to the indoor environment temperature, when the fan reverses, the inlet air temperature detected by the environment temperature sensing bag is the temperature after passing through the heat exchanger, so that the difference value between the detected inlet air temperature and the actual environment temperature becomes large, and in one embodiment, when the difference value between the inlet air temperature and the indoor environment temperature is determined to be greater than a preset temperature threshold value, the fan motor of the air conditioner can be considered to be reversed.
However, in the case of an air conditioner using outdoor air as intake air, the temperature of the intake air is normally higher than the temperature of the supply air in the cooling mode, and the temperature of the intake air is lower than the temperature of the supply air in the heating mode. When the condition of fan reversal appears, in the refrigeration mode, the air inlet temperature that environment temperature sensing package detected will be less than air supply temperature, and in the heating mode, air inlet temperature will be higher than air supply temperature. In one embodiment, when the air conditioner is in a cooling mode, if the inlet air temperature is detected to be lower than the supply air temperature, the fan motor of the air conditioner can be considered to be in reverse rotation; when the air conditioner is in a heating mode, if the inlet air temperature is detected to be higher than the air supply temperature, the fan motor of the air conditioner can be considered to be reversed.
In each of the above embodiments, the air conditioner using indoor air as the inlet air may be provided with an inlet air temperature detection device for detecting the inlet air temperature, and the indoor environment temperature where the air conditioner is located may be detected by a room temperature detection device provided on an air conditioner remote controller or an air conditioner line controller. An air conditioner using outdoor air as inlet air can be provided with an inlet air temperature detection device for detecting inlet air temperature and an outlet air temperature detection device for detecting outlet air temperature.
The present invention also provides a specific embodiment to describe the method for determining whether the fan motor of the air conditioner is reversely rotated, however, it should be noted that the specific embodiment is only for better describing the present invention, and is not to be construed as a limitation to the present invention.
Four types of air conditioners are taken as examples and are mainly divided into two main types, one is an air conditioner taking indoor air as air inlet (referred to as a common air conditioner indoor unit for short) and the other is an air conditioner taking outdoor air as air inlet (referred to as a fresh air conditioner processor for short):
1) blowing type common air conditioner indoor unit and air suction type common air conditioner indoor unit
Fig. 2 is a schematic view showing a wind direction of an air blowing type general air conditioning indoor unit, and fig. 3 is a schematic view showing a wind direction of an air suction type general air conditioning indoor unit.
In normal operation, the ambient temperature detection device (ambient temperature sensing bulb) of the indoor unit of the air conditioner shown in fig. 2 and 3 detects the temperature of the intake air (i.e., the temperature of the return air in the room, i.e., the temperature of the room in the room), and therefore, when the indoor unit of the air conditioner is in normal operation, the temperature detected by the ambient temperature sensing bulb is close to the ambient temperature.
However, when the fan motor of the air conditioner rotates reversely, the temperature detected by the environmental temperature sensing bulb is greatly different from the environmental temperature due to heat exchange of the heat exchanger.
Based on the principle, whether the fan motors of the air blowing type common air conditioner indoor unit and the air suction type common air conditioner indoor unit are reversely rotated can be determined in the following modes:
when the air conditioner is in the refrigeration mode, if the fan reverses, circulating air just can follow the air outlet air inlet and follow the air intake air-out, like this, the inlet air temperature that the environment temperature sensing package detected is the temperature behind the heat exchanger, therefore the inlet air temperature that the environment temperature sensing package detected and actual ambient temperature's difference can grow. Specifically, the ambient temperature can be detected by a temperature sensing bulb on the air conditioner line controller (or remote controller). Therefore, the air inlet temperature detected by the environment temperature sensing bulb can be compared with the environment temperature (namely, the indoor environment temperature) detected by the remote controller, if the difference is not large, the fan motor is normally operated, and if the air inlet temperature is much lower than the indoor environment temperature, the air inlet temperature detected by the environment temperature sensing bulb is the temperature after passing through the heat exchanger, so that the reverse operation of the fan motor at the moment can be determined.
When the air conditioner is in a heating mode, the air conditioner is just opposite to the air conditioner in a cooling mode, and if the difference between the inlet air temperature detected by the environment temperature sensing bulb and the indoor environment detected by the temperature sensing bulb on the line controller (or the remote controller) is not large, the operation of the fan motor is normal; if the inlet air temperature detected by the environment temperature sensing bulb is higher than the indoor environment detected by the temperature sensing bulb on the line controller (or the remote controller), the inlet air temperature detected by the environment temperature sensing bulb is the temperature after passing through the heat exchanger, and therefore the reverse operation of the fan motor can be determined.
2) Induced-draft type full fresh air conditioner processor and blowing type full fresh air conditioner processor
Fig. 4 shows a schematic view of the wind direction of the air-suction type fresh air conditioning processor, and fig. 5 shows a schematic view of the wind direction of the air-blowing type fresh air conditioning processor.
In normal operation, the ambient temperature detection means (ambient bulb) of the air conditioner processor shown in fig. 4 and 5 detects the temperature of the intake air (i.e., the outdoor ambient temperature). However, for the fresh air conditioner processor, the actual outdoor environment temperature cannot be effectively detected through the line controller or the remote controller, and therefore, the judgment cannot be performed through the judgment method of the ordinary air conditioner indoor unit.
Considering that the full fresh air conditioner processor is generally designed with an air supply temperature sensing bulb, the actual air supply temperature of the air conditioner can be detected through the air supply temperature sensing bulb, so that whether the fan motor operates normally can be judged by detecting and comparing the air inlet temperature detected by the environment temperature sensing bulb and the air supply temperature detected by the air supply temperature sensing bulb.
Specifically, whether the induced draft type fresh air conditioner handler and the blowing type fresh air conditioner handler are reversed may be determined in the following manner:
when the fresh air conditioner processor is in a refrigeration mode, the air supply temperature of the air conditioner is obviously lower than the ambient temperature (namely the air inlet temperature), so that the purpose of supplying cold fresh air to the air conditioning room is achieved. However, if the detected air supply temperature is higher than the air inlet temperature, it indicates that the actual air supply of the air conditioner firstly passes through the air supply temperature sensing bulb, then passes through the heat exchanger, and finally passes through the environment temperature sensing bulb, that is, the actual detected temperature of the air supply temperature sensing bulb is the environment temperature (air inlet temperature), and the actual detected temperature of the environment temperature sensing bulb is the air supply temperature, so that the reverse rotation operation of the fan motor can be judged.
When the full fresh air conditioner processor is in a heating mode, the air supply temperature of the air conditioner is obviously higher than the air inlet temperature, so that the purpose of supplying hot air to the air conditioning room for heating is achieved. However, if the air supply temperature is lower than the air supply temperature, it is indicated that the actual air supply of the air conditioner firstly passes through the air supply temperature sensing bulb, then passes through the heat exchanger, and finally passes through the environment temperature sensing bulb, that is, the actual detected temperature of the air supply temperature sensing bulb is the environment temperature (the air inlet temperature), and the actual detected temperature of the environment temperature sensing bulb is the air supply temperature, so that the reverse rotation operation of the fan motor can be judged.
In the above embodiment, whether the fan motor of the ordinary air conditioner indoor unit or the fresh air conditioner processor is reversely rotated is determined by using the original temperature detection device of the air conditioner indoor unit and a certain detection method.

In an embodiment, the determining module 603 may be specifically configured to determine that a fan motor of the air conditioner is reversely rotated when a difference between the intake air temperature and the indoor environment temperature is greater than a predetermined temperature threshold.
