Fig. 2 is a flowchart of a control method of an air conditioner operation according to an embodiment of the present application. As shown in fig. 2, the method comprises the steps of:
step S201, acquiring the outdoor environment temperature and the indoor environment temperature of the air conditioner at the starting time of the heating function of the air conditioner;
the outdoor environment temperature of the air conditioner is generally constant within a period of time, for example, constant within 20min and constant within 30 min; the indoor environment temperature of the air conditioner changes along with the opening of the heating function of the air conditioner, so that the outdoor environment temperature and the indoor environment temperature of the air conditioner are obtained as soon as the heating function of the air conditioner is started, and the follow-up realization of the accurate determination of the preset stay time length and the stay phase frequency of the compressor in the stay phase is facilitated;
Step S202, determining a preset stay time length of a stay phase of a compressor of an air conditioner according to outdoor environment temperature, and determining a stay phase frequency of the compressor according to the outdoor environment temperature and indoor environment temperature, wherein the operation frequency of the compressor is kept unchanged when the compressor is in the stay phase;
for example, the preset dwell time period of the dwell phase of the compressor is 0s, 30s, 120s, etc.; the stay stage frequency of the compressor is 56Hz, 66Hz, 70Hz and the like;
in the existing scheme, the preset stay time length of the stay phase and the frequency of the stay phase are set to be fixed values, the outdoor environment temperature and the indoor environment temperature are not considered, and however, the cold air prevention control is related to the indoor environment temperature, the outdoor environment temperature and the air conditioning system state. This fixed value setting is easy to cause: when the air conditioner under the partial low-temperature working condition reaches the condition of exiting the cold air prevention control, the compressor just enters or is in a frequency stay stage, at the moment, the air conditioner is switched to heat and normally operate, the air outlet temperature is rapidly reduced, cold air is heated and blown, and the expected cold air prevention effect cannot be achieved. In the scheme of the application, the indoor and outdoor environment temperatures are considered when the preset stay time length and the stay stage frequency are set, so that the occurrence of the above conditions is avoided.
Step S203, after the starting time, acquiring the temperature of the inner pipe of the air conditioner in real time, and determining whether to control the compressor to exit the cold air prevention control mode according to the first accumulated operation time length, the preset time length and the target time length of the compressor when the temperature of the inner pipe of the air conditioner is greater than or equal to the preset pipe temperature;
the inner tube temperature of the air conditioner is obtained in real time after the heating function of the air conditioner is started, namely, the magnitude relation between the inner tube temperature of the air conditioner and the preset tube temperature is dynamically compared, and the inner tube temperature of the air conditioner is indicated to be higher at the moment under the condition that the inner tube temperature of the air conditioner is larger than or equal to the preset tube temperature, so that the air conditioner can be ready to exit the cold air prevention control mode.
The target time length is the sum of a second accumulated operation time length and a preset stay time length, the second accumulated operation time length is associated with the stay phase frequency, the first accumulated operation time length is the accumulated time length from the starting time to the current time, and the second accumulated operation time length is the accumulated time length from the starting time to the initial time of the compressor entering the stay phase.
In the scheme, the second accumulated operation duration is set to be associated with the stay phase frequency, so that whether the compressor is controlled to exit the cold air prevention control mode is determined, the stay phase frequency is needed to be considered, and the stay phase frequency is a key factor for realizing the control function of improving the oil return of the compressor, so that the coupling between the control function of improving the oil return of the compressor and the heating cold air prevention control function is realized.
According to the control method for the operation of the air conditioner, the outdoor environment temperature and the indoor environment temperature of the air conditioner are obtained at the starting time of the heating function of the air conditioner, the preset residence time of the residence stage of the compressor of the air conditioner is determined according to the outdoor environment temperature, the residence stage frequency of the compressor is determined according to the outdoor environment temperature and the indoor environment temperature, the inner pipe temperature of the air conditioner is obtained in real time after the starting time, and whether the compressor is controlled to exit the cold air prevention control mode is determined according to the first accumulated operation time length, the preset time length and the target time length of the compressor under the condition that the inner pipe temperature of the air conditioner is greater than or equal to the preset pipe temperature. The coupling of the control function of improving the oil return of the compressor and the control function of heating and preventing cold air is realized. The problem that the existing treatment mode can not achieve the expected cold air prevention effect is solved. And heating comfort and running reliability are both considered.
In some specific schemes, the preset residence time length of the residence stage of the compressor of the air conditioner according to the outdoor environment temperature in step S202 is specifically implemented as follows:
under the condition that the outdoor environment temperature is smaller than the first preset outdoor environment temperature, determining the preset residence time to be the first preset residence time;
Determining the preset residence time to be a second preset residence time under the condition that the outdoor environment temperature is greater than or equal to the first preset outdoor environment temperature and less than or equal to the second preset outdoor environment temperature;
and under the condition that the outdoor environment temperature is greater than the second preset outdoor environment temperature, determining that the preset stay time is a third preset stay time, wherein the first preset outdoor environment temperature is less than the second preset outdoor environment temperature, the first preset stay time is greater than the second preset stay time, and the second preset stay time is greater than the third preset stay time.
For example, the first preset outdoor environment temperature is-7 ℃, the second preset outdoor environment temperature is 18 ℃, and the first preset residence time, the second preset residence time and the third preset residence time are respectively: 120s, 30s, 0s. Of course, such values are merely exemplary.
In some embodiments, determining the frequency of the stay phase of the compressor according to the outdoor environment temperature and the indoor environment temperature in step S202 includes:
step S2021: acquiring a temperature difference between an indoor environment temperature and an outdoor environment temperature;
step S2022: and determining the frequency of the stay phase of the compressor according to the temperature difference and the outdoor environment temperature, wherein the frequency of the stay phase is reduced along with the reduction of the outdoor environment temperature, and the frequency of the stay phase is reduced along with the increase of the temperature difference. I.e. the lower the outdoor ambient temperature the smaller the frequency setting of the stay phase, the lower the temperature difference indicates that the lower the outdoor ambient temperature is, the lower the frequency of the stay phase is, so that the expected cold air prevention effect can be achieved.
Specifically, according to the relation: f (F) 1 =c2×tw+c3×Δt+c4, where F 1 For dwell period frequency, c2 is the second coefficient, c3 is the third coefficient, c4 is a constant, and ΔT is the temperature difference. Specifically, the values of c2, c3, and c4 of different models are different, and a certain 3P cabinet machine is taken as an example, c2=0.39, c3= 0.0387, and c4=66.5.
In the method embodiment of the present application, step S2022: determining a dwell phase frequency of the compressor based on the temperature differential and the outdoor ambient temperature, comprising:
determining the initial stay phase frequency of the compressor according to the temperature difference value and the outdoor environment temperature;
under the condition that the frequency of the initial stay phase is smaller than the frequency preset minimum value, determining the frequency preset minimum value as the frequency of the final stay phase;
and under the condition that the frequency of the initial stay phase is larger than the preset maximum value of the frequency, determining the preset maximum value of the frequency as the frequency of the final stay phase.
That is, according to the relation: f (F) 1 The frequency of the residence phase of the compressor determined by =c2×tw+c3×Δt+c4 may be too small or too large, and in these cases, the preset minimum value of the frequency needs to be set to limit the lower limit value, so as to avoid the decrease of the reliability of the air conditioner caused by the slow oil return rate of the compressor.
The frequency preset maximum value is required to be set for limiting the upper limit value, so that the phenomenon that oil shortage or oil empty occurs in a system due to too high oil discharge rate of a compressor is avoided, and the operation reliability of an air conditioner is ensured.
