wherein, Q represents fresh air load, M represents preset fresh air volume, vn represents air specific volume, h1 represents outdoor side enthalpy value, and h2 represents indoor side enthalpy value.
Step S106, calculating to obtain the target capacity output of the compressor according to the outdoor temperature and the preset wind level;
specifically, firstly judging whether a preset wind gear is a high wind gear or not; if so, determining a first calculation rule corresponding to the high wind level according to the outdoor temperature and a preset temperature threshold; and calculating according to the first calculation rule to obtain the target capacity output of the compressor.
The target capacity output is used for representing capacity output corresponding to a preset frequency value of the compressor; preferably, the preset frequency value is 1Hz, in addition, other preset frequency values, such as 10Hz, may be used, and the embodiment of the present invention uses 1Hz as an example, and the other preset frequency values may be adjusted correspondingly according to 1 Hz. In practical application, the operation capability of the air conditioner has a large correlation with the operation frequency, the air quantity of the internal machine and the outside temperature (outside load). For example, in the 1.5P model, the displacement of the compressor is 10cm 3 For example,/rev, it is known through experimental calculation that the capacity output corresponding to 1Hz of the compressor is in a linear relation with the outer ring and the air volume, and the reference capacity output of the 1.5P model is generally 52W, where the reference capacity output can be adjusted according to different compressors and different numbers of matches.
In addition, the preset temperature threshold includes a first temperature threshold, a second temperature threshold, and a third temperature threshold; the second temperature threshold is greater than the first temperature threshold and less than the third temperature threshold; the process of determining the first calculation rule corresponding to the high wind gear according to the outdoor temperature and the preset temperature threshold value includes: if the outdoor temperature is not greater than the first temperature threshold, the first calculation rule is: q1=q Base group The method comprises the steps of carrying out a first treatment on the surface of the Wherein Q1 represents a target capacity output, Q Base group Representing a baseline capacity output; if the outdoor temperature is greater than the first temperature threshold and not greater than the second temperature threshold, the first calculation rule is: q1=0.9q Base group The method comprises the steps of carrying out a first treatment on the surface of the If the outdoor temperature is greater than the second temperature threshold and not greater than the third temperature threshold, the first calculation rule is: q1=0.85Q Base group The method comprises the steps of carrying out a first treatment on the surface of the If the outdoor temperature is greater than the third temperature threshold, the first calculation rule is: q1=0.8q Base group 。
For ease of understanding, this is illustrated herein. If the first temperature threshold is set to 30 ℃, the second temperature threshold35 ℃, the third temperature threshold value is 43 ℃, and the outdoor temperature is T Outer part When the preset wind gear is a high wind gear:
(1) When T is Outer part At 30 ℃ or less, the first calculation rule outputs q1=q for the target capacity Base group ；
(2) When the temperature is less than 30 ℃ and less than T Outer part At less than or equal to 35 ℃, at this time, the first calculation rule is that the target capacity output Q1=0.9Q Base group ；
(3) When the temperature is less than 35 ℃ T Outer part At less than or equal to 43 ℃, at this time, the first calculation rule is that the target capacity output Q1=0.85Q Base group ；
(4) When T is Outer part At > 43 ℃, then the first calculation rule is the target capacity output q1=0.8q Base group 。
Furthermore, the method comprises the following steps: if the preset wind gear is a wind gear, correcting the first calculation rule according to a preset first correction coefficient to obtain a second calculation rule corresponding to the wind gear, and calculating according to the second calculation rule to obtain the target capacity output of the compressor; wherein the first correction coefficient is 0.8. At the outdoor temperature T Outer part When the first calculation rules are in different ranges, the first calculation rules are not the same, and for the case that the preset wind gear is the middle wind gear, the first correction coefficient is multiplied only on the basis of the different first calculation rules under the condition of the same outdoor temperature and the preset temperature threshold value. For example, in the case that the preset wind gear is the wind gear, at this time, (1) when T Outer part At less than or equal to 30 ℃, the second calculation rule is that the target capacity outputs Q1=0.8×Q Base group The method comprises the steps of carrying out a first treatment on the surface of the (2) When the temperature is less than 30 ℃ and less than T Outer part At less than or equal to 35 ℃, the second calculation rule is that the target capacity outputs Q1=0.8x0.9Q Base group The method comprises the steps of carrying out a first treatment on the surface of the (3) When the temperature is less than 35 ℃ T Outer part At less than or equal to 43 ℃, the second calculation rule is that the target capacity output Q1=0.8×0.85Q Base group The method comprises the steps of carrying out a first treatment on the surface of the (4) When T is Outer part At > 43 ℃, the second calculation rule is that the target capacity output q1=0.8x0.8q Base group . Therefore, for the case that the preset wind gear is the middle wind gear, the first calculation rule is corrected through the first correction coefficient to obtain a second calculation rule corresponding to the middle wind gear, and the target capacity output is calculated according to the second calculation rule to adjust the adjusting frequency of the middle wind gear, thereby ensuring thatThe fresh air load counteracting effect of the middle wind shield is achieved, and therefore the indoor temperature fluctuation-free control effect and the room comfort are guaranteed not to be affected.
And, the method further comprises: if the preset wind level is a low wind level, correcting the first calculation rule according to a preset second correction coefficient to obtain a third calculation rule corresponding to the low wind level, and calculating according to the third calculation rule to obtain the target capacity output of the compressor; wherein the second correction coefficient is 0.6. The specific reference may be made to the case that the preset wind gear is the middle wind gear, and the embodiments of the present invention are not described in detail herein.
Step S108, calculating and obtaining the adjustment frequency of the compressor according to the fresh air load and the target capacity output;
specifically, according to the calculated fresh air load Q and the target capacity output Q1, the adjustment frequency of the compressor can be calculated according to Q/Q1, and the adjustment frequency can be also called increasing frequency, so that the adjustment frequency can offset the fresh air load, and therefore the room temperature is guaranteed not to fluctuate when the fresh air is started.
Step S110, adjusting the frequency of the compressor according to the adjustment frequency, and controlling the compressor to operate according to the adjusted frequency.
Specifically, when the frequency of the compressor is adjusted, the adjusting frequency is used for counteracting the fresh air load, so that when the fresh air module is started, the comfort of a room is not influenced by adjusting the frequency of the compressor, and the experience of a user is improved.
According to the frequency control method for the compressor, provided by the embodiment of the invention, the adjustment frequency of the compressor is obtained through the fresh air load and the target capacity output, so that the fresh air load is counteracted through the adjustment frequency, the room temperature is kept unchanged when the fresh air is started, and the user experience is improved.
For ease of understanding, here take the form of Q Base group Illustrated as 52W. As shown in fig. 2, the method comprises the following steps:
step S202, starting fresh air; if the indoor temperature is stable, after the air conditioner stably operates, when a fresh air module starting instruction sent by a user through a remote controller or remote control equipment is received, the controller triggers the fresh air module to operate;
step S204, obtaining detection parameters; wherein, the detection parameters include: indoor temperature, indoor relative humidity, outdoor temperature, and outdoor relative humidity; such as the indoor temperature T Inner part At 27℃and indoor relative humidity47% of the outdoor temperature T Outer part 35 ℃ and indoor relative humidity->40%;
step S206, calculating a fresh air load Q; if the temperature and the humidity are found in a preset temperature relative humidity meter according to the indoor temperature, the indoor relative humidity, the outdoor temperature and the outdoor relative humidity, the h1 is 71.6kj/kg, the h2 is 53.8kj/kg, and the specific volume Vn of air is 0.88m3/kg; the fresh air quantity M set by a user is 40M 3 /h(0.011m 3 And/s), and calculating the fresh wind load Q to be 223W according to Q=M (h 1-h 2)/Vn.
Step S208, calculating capacity output Q1 corresponding to 1Hz of the compressor, namely target capacity output; specifically, the user sets the air conditioner wind speed to be the middle wind speed, and at this time, the capacity output Q1 corresponding to the compressor 1Hz is 0.9×52×0.8=37W.
