The present invention will be described in detail below by way of examples.
A method of increasing capacity for airborne cooling, as shown in fig. 1, the method comprising the steps of:
s1: and judging whether the running frequency of the compressor needs to be increased according to the indoor temperature and the outdoor temperature, and if so, executing S2.
S2: and (4) after the running frequency of the compressor is increased, detecting whether the pressure of the air conditioning system exceeds the standard, and if so, executing S3.
S3: the rotating speed of the outer fan is improved.
In step S2, the compressor operating frequency is increased, but the increased compressor operating frequency results in an increase in system pressure.
The condition that the system pressure is high can occur due to the increase of the running frequency of the compressor, the condensing pressure can be released by increasing the rotating speed of the outer fan, namely, the wind speed of the outer fan is increased, the heat exchange between the condenser and the external environment is more sufficient, so that the condensing temperature is reduced, the condensing pressure is reduced, the reliable running of the whole machine is ensured, the influence on the noise of the outer fan due to the increase of the rotating speed of the outer fan is large, and the principle of increasing the rotating speed of the outer fan is that the system pressure is ensured to.
Specifically, the method for increasing the rotating speed of the outer fan comprises the following steps:
s31: increasing the rotating speed of 50r/min on the basis of the rotating speed of the current outer fan;
s32: the outer fan operates for a first preset time;
s33: and judging whether the current system pressure is reduced to be lower than a first pressure threshold value, if so, keeping the current outer fan rotating speed, and if not, returning to S31.
Typically, the first preset time period for the operation of the external fan is 1 min.
Thus, the following beneficial effects can be achieved:
1) the compressor can operate the maximum frequency corresponding to the outdoor environment temperature, and the refrigeration capacity can be ensured to be exerted to the maximum;
2) on the premise of meeting the system reliability, the lowest noise value of the outdoor unit can be reached.
When the indoor temperature is reduced, the pressure on the evaporator side is reduced, the condensing pressure is also reduced correspondingly, and the system reliability is better.
S4: when the indoor temperature is reduced to the comfortable temperature of human body, the running frequency of the compressor and the wind speed of the external fan are reduced.
The comfortable temperature of the human body is as follows: the difference between the outdoor temperature and the indoor temperature is more than or equal to the indoor temperature when the temperature is 15 ℃, or the indoor temperature when the indoor temperature reaches 27 ℃.
When the temperature reaches the comfortable temperature of a human body, PID control is executed according to the temperature frequency set by a user, the difference value between the indoor temperature and the set temperature is monitored in real time, the frequency is reduced by a certain gradient when the indoor temperature is to reach the temperature set by the user, the condensation pressure is reduced, the rotating speed of the outer fan is reduced at the moment, and the rotating speed requirement of the outer fan is ensured on the premise of meeting the reliability.
Specifically, the method for reducing the rotating speed of the external fan comprises the following steps:
s41: reducing the rotating speed of the current outer fan by 50r/min on the basis of the rotating speed of the current outer fan;
s42: the outer fan operates for a second preset time;
s43: and judging whether the current system pressure is reduced to be lower than a second pressure threshold value, if so, keeping the current rotating speed of the outer fan, and if not, returning to the step S41.
Because the system refrigerant pressure has hysteresis quality, compressor frequency reduces the back, and system pressure still can be very high, needs the detection system pressure value, reduces outer fan rotational speed according to the pressure value. Typically, the second preset time period for the operation of the external fan is 1 min.
Specifically, as shown in fig. 2, the step S1 includes:
s11: and starting the air conditioner.
S12: the indoor temperature and the outdoor temperature are detected.
S13: and judging whether the outdoor temperature is greater than or equal to a first preset temperature or not, and whether the outdoor temperature minus the indoor temperature is less than or equal to a second preset temperature or not, if so, executing S2, and if not, exiting.
Specifically, the first preset temperature may be 45 ℃ and the second preset temperature may be 5 ℃.
Specifically, the step S2 includes:
s21: the operating frequency of the compressor is increased.
When the outdoor environment temperature is high, the condition that the compressor reduces the frequency can occur in the whole machine due to protection, so that the working load of the compressor is not full, and the condition of poor temperature reduction effect occurs. In practice, however, it has been found that in many cases, although the overall unit is protected, the system reliability is satisfactory when the operating frequency of the compressor is increased. One method that may be employed at this time is to increase the compressor operating frequency to a maximum frequency corresponding to the outdoor ambient temperature to ensure maximum cooling capacity output. The maximum frequency may be determined by looking up an "outdoor temperature-maximum frequency" look-up table stored in the air conditioner memory. In another embodiment provided by the present invention, the compressor operating frequency can be increased as follows:
1) and detecting the indoor target temperature.
2) It is determined whether the indoor target temperature is equal to or less than 22 degrees in the cooling mode. The air conditioner requires a high cooling/heating capacity in the above temperature range.
3) If the judgment result in the step 2) is yes, it indicates that the air conditioner needs to have higher cooling/heating capacity, and the operation frequency of the compressor also needs to be correspondingly increased, and at this time, the first correction parameter is set to be 1.05.
4) And obtaining the frequency increase value manually input by the user.
In this step, the frequency increment value may be the number of frequencies to be actually increased, such as 50Hz, 76Hz, etc.; the number of changes in frequency increase may be, for example, ± 10, ± 15, etc.
The manual input mode of the user can be input through a remote controller, and when the frequency change value is the frequency number which is actually increased, the frequency change value can be input through a number key on the remote controller; and when the frequency is increased, the frequency can be input by the pressing times of the increased and decreased keys on the remote controller.
Of course, the input can also be performed through the display control panel of the air conditioner, and the input mode is similar to that of the remote controller, so that the further description is omitted.
5) And judging whether the frequency switch manually adjusted by the user is turned on, if so, executing the step 6), and otherwise, executing the step 7).
The manual frequency adjustment switch is equivalent to an enabling switch for manual frequency adjustment, and can be arranged on the display control panel of the air conditioner, also can be arranged on the remote controller, and can be provided with an independent key or a combined key.
The current state of the frequency switch manually adjusted by the user is stored through a register arranged in the indoor unit of the air conditioner, and when the judgment is carried out in the step, only data are read from the register and the judgment is carried out.
6) Judging whether the input frequency increasing value exceeds a set value or not after the input frequency increasing value is applied, and if so, executing a step 8); otherwise, 7) is executed.
Wherein the set value is a maximum operable range of a compressor of the air conditioner, for example, 5Hz to 130 Hz. If the current operating frequency of the compressor is X, the step determines whether X plus the frequency increment exceeds the maximum operable range of the compressor.
For the case where the frequency variation value is the actual frequency value directly input, this step adds the actual frequency value to the current operating frequency of the compressor, for example, X +50Hz, X +100 Hz. When the frequency increment value is the frequency change number, the following calculation is carried out:
the current operating frequency of the compressor + ((the number of changes) × the preset frequency step) is, for example, X +10 × the preset frequency step, etc.
In a preferred embodiment of the invention, the predetermined frequency step is 3Hz to 20Hz, preferably 5 Hz. And, the preset frequency step can be modified as required.
7) Multiplying the first correction parameter by the frequency increment value to obtain a new frequency increment value, and applying the new frequency increment value. That is, when it is judged through the previous step that the operating frequency range of the compressor is not exceeded, the new frequency increase value is applied to the current operating frequency of the compressor so that the compressor operates at the applied frequency. This step is finished and then 9) is executed.
8) The set value is taken as the frequency value.
That is, when it is determined that the frequency variation value is applied beyond the operating frequency range of the compressor (i.e., the set value) by the previous step, the set value is directly used as the frequency value, and the compressor operates at the frequency of the set value. For example:
when the frequency variation value is an actual frequency, assuming that the operating frequency range of the compressor is 30Hz to 130Hz, the current operating frequency of the compressor is 100Hz, and the frequency variation value is +40Hz, 140Hz which is 100Hz +40Hz is greater than 130Hz, and thus 130Hz is used as the operating frequency of the compressor.
9) And (6) ending.
It should be noted that, when the user manually adjusts the frequency switch to be off, the air conditioner may operate in the variable frequency air conditioner mode or the fixed frequency air conditioner mode.
S22: and judging whether the system pressure exceeds the standard, if so, executing S3, and otherwise, executing S4.
Further, the invention also provides a method for improving the capacity of air-conditioning cooling, which comprises the following steps:
s01: and starting the air conditioner.
S02: the indoor temperature and the outdoor temperature are detected.
S03: and judging whether the outdoor temperature is greater than or equal to a first preset temperature and whether (the outdoor temperature-the indoor temperature) is less than or equal to a second preset temperature, if so, executing S04, and if not, exiting.
