Therefore, the target operating frequency can be matched with the system demand load, and the demand of a user on the indoor temperature is met.
By adopting the method for refrigerating the air conditioner, which is provided by the embodiment of the disclosure, the outdoor fan is closed when the outdoor environment temperature of the air conditioner is smaller than the temperature threshold value, so that the outdoor heat exchange efficiency is greatly reduced, the high-pressure and the suction superheat degree of the system can be reduced while the frequent freezing protection of the air conditioner is avoided, the liquid return operation of the compressor is avoided, and the service life of the compressor is prolonged. The air conditioner determines the target operating frequency of the compressor according to the target temperature and the indoor environment temperature, adjusts the operating frequency of the compressor to the target operating frequency, and can obtain the refrigerating load of the air conditioner system through the target temperature and the indoor environment temperature, so that the operating frequency of the compressor can be matched with the system pressure, and the refrigerating efficiency is improved.

S02, the air conditioner starts the compressor and closes the outdoor fan under the condition that the outdoor environment temperature is smaller than the temperature threshold value.
S31, the air conditioner judges whether the temperature of the inner coil reaches the set temperature.
S32, under the condition that the temperature of the inner coil pipe does not reach the set temperature, the air conditioner adjusts the running frequency of the compressor according to the indoor air outlet temperature.
Under the condition that the temperature of the inner coil pipe reaches the set temperature, the temperature of the inner coil pipe is higher at the moment, the air conditioner cannot enter freezing protection, and the running state of the compressor is matched with the refrigerating load, so that the refrigerating requirement of a user can be met, the running frequency of the compressor is kept unchanged by the air conditioner, the refrigerating effect of the air conditioner is maintained, and the stable running of the air conditioner is ensured.
By adopting the method for refrigerating the air conditioner provided by the embodiment of the disclosure, the air conditioner judges whether the temperature of the inner coil reaches the set temperature. Under the condition that the temperature of the inner coil pipe does not reach the set temperature, the temperature of the inner coil pipe is too low at the moment, the air conditioner can be frequently subjected to freezing protection, so that the air conditioner is not refrigerated stably enough, namely, the running state of the air conditioner can not meet the refrigerating requirement of a user at the moment, therefore, the running frequency of the compressor is continuously regulated according to the indoor air outlet temperature, the running stability of the air conditioner is improved, the indoor refrigerating effect is improved, the refrigerating requirement of the user is met, and the user experience is improved.
The embodiment of the disclosure provides a method for refrigerating an air conditioner. As shown in fig. 4, the method includes:
s01, the air conditioner detects the outdoor environment temperature.
S02, the air conditioner starts the compressor and closes the outdoor fan under the condition that the outdoor environment temperature is smaller than the temperature threshold value.
S31, the air conditioner judges whether the temperature of the inner coil reaches the set temperature.
S41, judging whether the indoor air outlet temperature reaches the set temperature or not under the condition that the temperature of the inner coil pipe does not reach the set temperature.
S42, judging whether the running frequency of the compressor reaches a frequency threshold value or not under the condition that the indoor air outlet temperature reaches the set temperature.
S43, when the operation frequency of the compressor does not reach the frequency threshold value, the operation frequency of the compressor is increased.
Wherein the frequency threshold is associated with an energy efficiency ratio of the compressor.
By adopting the method for refrigerating the air conditioner provided by the embodiment of the disclosure, when the temperature of the inner coil pipe of the air conditioner does not reach the set temperature, the temperature of the inner coil pipe is too low at the moment, so that the air conditioner can frequently enter into freezing protection, namely the running state of the air conditioner can not meet the refrigerating requirement of a user. Therefore, whether the indoor air outlet temperature reaches the set temperature is further judged, and when the indoor air outlet temperature reaches the set temperature, the indoor air outlet temperature is higher at the moment, so that the running state of the air conditioner at the moment can be further determined to be not in accordance with the system load corresponding to the refrigerating requirement of a user. In order to improve the refrigerating effect, the air conditioner judges whether the operating frequency of the compressor reaches a frequency threshold value, and improves the operating frequency of the compressor under the condition that the operating frequency of the compressor does not reach the frequency threshold value. By judging whether the running frequency of the compressor reaches the frequency threshold, the condition that the energy efficiency ratio is reduced and the energy consumption is overlarge and the heat exchange efficiency is low due to the fact that the frequency of the compressor is too high can be avoided. On the basis of ensuring the energy efficiency ratio of the compressor, the frequency and the compression ratio of the compressor can be improved as much as possible by improving the running frequency of the compressor, and the fault occurrence rate is reduced.
Optionally, the air conditioner adjusts the operation frequency of the compressor according to the indoor air outlet temperature, and further includes: and under the condition that the indoor air outlet temperature does not reach the set temperature, the air conditioner maintains the operating frequency of the compressor or reduces the operating frequency of the compressor.
Therefore, when the indoor air outlet temperature of the air conditioner does not reach the set temperature, the temperature of the inner coil pipe is too low, so that the air conditioner can frequently enter the freezing protection, the running frequency of the compressor can be kept, or the running frequency of the compressor is reduced until the temperature difference between the indoor air outlet temperature and the set temperature is smaller than the temperature difference threshold value. The temperature of the inner coil pipe can further reach the set temperature by reducing the operation frequency of the compressor, so that the probability of entering freezing protection is reduced, and the operation stability of the air conditioner is improved.
Optionally, after the air conditioner determines whether the operation frequency of the compressor reaches the frequency threshold, the method further includes: and under the condition that the operating frequency of the compressor reaches a frequency threshold value, the air conditioner starts the outdoor fan.
In this way, when the operation frequency of the compressor reaches the frequency threshold, it is indicated that the compressor of the air conditioner reaches the highest energy efficiency ratio, but the refrigeration effect of the air conditioner cannot meet the requirements of users. If the operation frequency of compression is further increased in order to increase the cooling effect, the energy efficiency ratio of the compressor is lowered, and the cooling effect of the air conditioner is lowered. Therefore, the air conditioner starts the outdoor fan to further improve the energy efficiency ratio of the compressor, so that the indoor refrigeration requirement of a user is met, and the user experience is improved.
Optionally, after the air conditioner determines whether the operation frequency of the compressor reaches the frequency threshold, the method further includes: and under the condition that the operating frequency of the compressor does not reach the frequency threshold value, the air conditioner increases the operating frequency of the compressor.
Therefore, under the condition that the operating frequency of the compressor does not reach the frequency threshold value, and the energy efficiency ratio can be further improved by improving the operating frequency of the compressor. By improving the operation frequency of the compressor, the refrigerating capacity of the air conditioner can be improved, and the refrigerating requirement of a user can be met.
Optionally, the air conditioner increases the operation frequency of the compressor if the operation frequency of the compressor does not reach the frequency threshold, including: the air conditioner determines the compensation frequency of the compressor according to the current indoor environment temperature and the set temperature; the air conditioner increases the operating frequency of the compressor according to the compensation frequency.
Therefore, the air conditioner determines the compensation frequency of the compressor according to the indoor current environment temperature and the set temperature, and improves the operation frequency of the compressor according to the compensation frequency, so that the compensation frequency can be matched with the refrigerating capacity which is lack for the air conditioner to reach the set temperature, the refrigerating capacity of the air conditioner is further improved, and the indoor refrigerating effect is improved.
Optionally, determining the compensation frequency of the compressor according to the current environmental temperature and the set temperature in the room includes: calculating a second temperature difference between the current ambient temperature and the set temperature; and determining the compensation frequency corresponding to the second temperature difference according to the corresponding relation between the second temperature difference and the compressor frequency, which is preserved in advance.
Therefore, the second temperature difference is the temperature difference between the current indoor environment and the user demand temperature when the operating frequency of the compressor reaches the frequency threshold, so that the refrigerating capacity which is lack when the air conditioner reaches the user demand temperature when the operating frequency of the compressor reaches the frequency threshold can be represented. Therefore, the compensation frequency is obtained through the second temperature difference, and the compensation frequency can be matched with the refrigerating capacity which is lack when the air conditioner needs to reach the set temperature, so that the refrigerating capacity of the air conditioner is further improved, and the indoor refrigerating effect is improved.
Optionally, the air conditioner starts an outdoor fan, including: the air conditioner determines the target fan rotating speed of the outdoor fan according to the current indoor environment temperature and the set temperature; the air conditioner adjusts the rotational speed of the outdoor fan to a target fan rotational speed.
Thus, the air conditioner determines the target fan rotating speed of the outdoor fan according to the indoor current environment temperature and the set temperature, and adjusts the rotating speed of the outdoor fan to the target fan rotating speed. The current indoor temperature condition can be represented through the current environment temperature and the set temperature, so that the rotating speed of the outdoor fan can be matched with the indoor current temperature condition, and the refrigerating effect is improved.
Optionally, the air conditioner determines a target fan rotation speed of the outdoor fan according to the current indoor environment temperature and the set temperature, including; calculating a second temperature difference between the current ambient temperature and the set temperature; and determining the target fan rotating speed corresponding to the second temperature difference according to the corresponding relation between the second temperature difference and the fan rotating speed, which is stored in advance.
In this way, a second temperature difference between the current environment temperature and the set temperature is calculated, wherein the second temperature difference is a temperature difference between the current indoor environment and the user demand temperature when the operating frequency of the compressor reaches the frequency threshold, so that the refrigerating capacity which is lack when the air conditioner reaches the user demand temperature can be represented when the operating frequency of the compressor reaches the frequency threshold. The air conditioner determines the target fan rotating speed corresponding to the second temperature difference value according to the corresponding relation between the second temperature difference value and the fan rotating speed stored in advance, so that the energy efficiency ratio of the air conditioner is improved, the rotating speed of the outdoor fan is matched with the refrigerating capacity which is required to reach the temperature required by a user and is lack of the refrigerating capacity of the air conditioner, the refrigerating capacity of the air conditioner is compensated under the condition that the running frequency of the compressor reaches a frequency threshold value, the requirement of the user on the indoor temperature is met, and the user experience is improved.
