Fig. 3 is the flow chart of the electricity-saving operation method of inverted air conditioners of the present invention.That is to say, this flowchart text can make the method for inverted air conditioners (not shown) economize on electricity.
No matter the mode of operation of inverted air conditioners is arranged to energy-saving mode, still is arranged to general modfel (S31), all is identical.Here, if the mode of operation of inverted air conditioners is arranged to general modfel, the work of inverted air conditioners is controlled as general refrigeration work pattern (S32).
In addition, if the mode of operation of inverted air conditioners is arranged to energy-saving mode, the peak frequency (not shown) of inverted air conditioners compressor is determined (S33) by the indoor and outdoors temperature.
Then, final operating frequency determines according to the difference of maximum operation frequency and preferred temperature and indoor temperature, inverted air conditioners thereupon work (S34).At this moment, if inverted air conditioners with maximum operation frequency work, and in decision after whether energy-saving mode should stop, decision continues to keep energy-saving mode, then final operating frequency is determined once more, inverted air conditioners carries out refrigeration work (S35) thereupon.
To contrast the method that Fig. 4-Figure 18 more detailed description inverted air conditioners reduces power consumption below.
At first contrast Fig. 4-Figure 12 the experiment with the indoor and outdoors variations in temperature of a test refrigerating capacity of inverted air conditioners and power consumption is described in detail in detail.
Fig. 4 is some indoor and outdoors temperature conditions that the present invention considers.
As shown in the figure, done such experiment: set 21 points by the indoor and outdoors variation of temperature, the variable quantity of corresponding each refrigerating capacity of setting up an office with various frequencies compared.Below the contrast of the experimental result on various frequencies Fig. 5-Figure 12 is illustrated in detail.
Fig. 5-Figure 12 illustrates the variable quantity of refrigerating capacity with frequency.Here, the operating frequency of being tested is 58Hz, 52Hz, and 47Hz and 35Hz, outdoor temperature is 35 ℃, indoor temperature is 27 ℃.
As shown in Figure 5 and Figure 6, is that the variation of benchmark and outdoor temperature are when being the variation of benchmark with 27 ℃ of indoor temperatures in the test indoor temperature with 35 ℃ of outdoor temperatures, if frequency (operating frequency) is 58Hz, the variable quantity that the reduction of refrigerating capacity indoor temperature is 6 ℃ is 2.6: 1 with the ratio that the refrigerating capacity outdoor temperature reduces by 6 ℃ variable quantity.That is to say, refrigerating capacity 1924[Kcal/h during 27 ℃ of indoor temperatures] refrigerating capacity 1525[Kcal/h when deducting 21 ℃ of indoor temperatures] obtain a value, refrigerating capacity 2077[Kcal/h during 29 ℃ of outdoor temperatures] refrigerating capacity 1525[Kcal/h when deducting 35 ℃ of outdoor temperatures] also obtain a value, the ratio of these two values is 2.6: 1.
As shown in Figure 7 and Figure 8, is that the variation of benchmark and outdoor temperature are when being the variation of benchmark with 27 ℃ of indoor temperatures in the test indoor temperature with 35 ℃ of outdoor temperatures, if frequency (operating frequency) is 52Hz, the variable quantity that the reduction of refrigerating capacity indoor temperature is 6 ℃ is 2.1: 1 with the ratio that the refrigerating capacity outdoor temperature reduces by 6 ℃ variable quantity.That is to say, refrigerating capacity 1753[Kcal/h during 27 ℃ of indoor temperatures] refrigerating capacity 1391[Kcal/h when deducting 21 ℃ of indoor temperatures] obtain a value, refrigerating capacity 1929[Kcal/h during 29 ℃ of outdoor temperatures] refrigerating capacity 1753[Kcal/h when deducting 35 ℃ of outdoor temperatures] also obtain a value, the ratio of these two values is 2.1: 1.
As Fig. 9 and shown in Figure 10, is that the variation of benchmark and outdoor temperature are when being the variation of benchmark with 27 ℃ of indoor temperatures in the test indoor temperature with 35 ℃ of outdoor temperatures, if frequency (operating frequency) is 47Hz, the variable quantity that the reduction of refrigerating capacity indoor temperature is 6 ℃ is 2: 1 with the ratio that the refrigerating capacity outdoor temperature reduces by 6 ℃ variable quantity.That is to say, refrigerating capacity 1605[Kcal/h during 27 ℃ of indoor temperatures] refrigerating capacity 1271[Kcal/h when deducting 21 ℃ of indoor temperatures]] obtain a value, refrigerating capacity 1769[Kcal/h during 29 ℃ of outdoor temperatures] refrigerating capacity 1605[Kcal/h when deducting 35 ℃ of outdoor temperatures] also obtain a value, the ratio of these two values is 2: 1.
As Figure 11 and shown in Figure 12, is that the variation of benchmark and outdoor temperature are when being the variation of benchmark with 27 ℃ of indoor temperatures in the test indoor temperature with 35 ℃ of outdoor temperatures, if frequency is 35Hz, the variable quantity that the reduction of refrigerating capacity indoor temperature is 6 ℃ is 1.4: 1 with the ratio that the refrigerating capacity outdoor temperature reduces by 6 ℃ variable quantity.That is to say, refrigerating capacity 1195[Kcal/h during 27 ℃ of indoor temperatures] refrigerating capacity 965[Kcal/h when deducting 21 ℃ of indoor temperatures] obtain a value, refrigerating capacity 1360[Kcal/h during 29 ℃ of outdoor temperatures] refrigerating capacity 1195[Kcal/h when deducting 35 ℃ of outdoor temperatures] also obtain a value, the ratio of these two values is 1.4: 1.
So because the reduction of indoor temperature and reducing greatly, it is 2: 1 that the average specific that corresponding refrigerating capacity variable quantity falls in corresponding refrigerating capacity variable quantity and 6 ℃ of outdoor temperatures falls in 6 ℃ of indoor temperatures to refrigerating capacity when big frequency.
To contrast Figure 13 below, cold energy power in the above-mentioned experiment will be described with the variation that indoor temperature and outdoor temperature change.
Figure 13 illustrates the variation that refrigerating capacity changes with indoor temperature and outdoor temperature.
As shown in the figure, those represent that refrigerating capacities are-1/2 with the slope of the straight line of the variation of indoor temperature and outdoor temperature variation among the figure.That is to say that in the present invention, when outdoor temperature increase and outdoor load (by the load that extraneous air provided) increase, the refrigerating capacity of inverted air conditioners evaporimeter (not shown) reduces, thereby operating frequency begins to increase, refrigerating capacity also begins to increase.In addition, according to the present invention, no matter how user's load (user is in order to control the load that indoor temperature produces in its temperature that sets) increases, and how operating frequency increases, and the refrigerating capacity of inverted air conditioners evaporimeter (not shown) all increases with the increase of indoor temperature.Here, operating frequency will contrast Figure 14 with the variation of indoor and outdoor load and Figure 15 is described.
Figure 14 explanation is the variation of operating frequency during with 1 ℃ interval variation by indoor temperature of the present invention.
Figure 15 explanation is the variation of operating frequency during with 1.5 ℃ interval variation by indoor temperature of the present invention.
As Figure 14 and shown in Figure 15, make the scope of the indoor temperature that operating frequency changes influence the power consumption of inverted air conditioners, user's changes in temperature sense and comfort.So the temperature range of power save function is set when comparing with conventional refrigerating operation.Here, average indoor temperature will contrast Figure 16 and Figure 17 is described.
Average indoor temperature when Figure 16 illustrates indoor temperature with 1 ℃ interval variation.That is to say that if what can make indoor temperature that operating frequency changes is 1 ℃ at interval, average indoor temperature is higher than 1.1 ℃ of the average indoor temperatures of conventional refrigerating operation.
Average indoor temperature when Figure 17 illustrates indoor temperature with 1.5 ℃ interval variation.That is to say that if what can make indoor temperature that operating frequency changes is 1.5 ℃ at interval, average indoor temperature is higher than 0.6 ℃ of the average indoor temperature of conventional refrigerating operation.
So, if operating frequency changes during with 1 ℃ interval variation in indoor temperature,, compare with conventional refrigerating operation by the power consumption of inverted air conditioners of the present invention, reduce by 13%.In addition, if operating frequency changes during with 1.5 ℃ interval variation in indoor temperature, the power consumption of inverted air conditioners is compared with conventional refrigerating operation, reduces by 8.7%.That is to say that according to the experimental result among Figure 16 and Figure 17, when indoor temperature during with 1.5 ℃ interval variation, the difference of average indoor temperature is little, so operating frequency changes.
Contrast Figure 18 describes the poor operating frequency of setting operating frequency and setting according to the preferred temperature of indoor temperature and user's setting below.
Figure 18 is operating frequency is set in an explanation according to the difference of indoor temperature and user's design temperature (preferred temperature) a table.That is to say that the peak frequency that the indoor and outdoor temperature conditions is determined is used to control final frequency.Here, operating frequency is set according to the difference of indoor temperature user design temperature (preferred temperature), and is stored in the above-mentioned ROM table.
As shown in figure 15, if indoor temperature is 30 ℃, outdoor temperature is 29 ℃, and the preferred temperature that the user sets is 27 ℃, and then peak frequency is set at 62Hz.In addition, the difference of the preferred temperature that indoor temperature and user set is 3 ℃, so final frequency is confirmed as peak frequency, and the inverted air conditioners compressor is worked with 62Hz.
On the other hand, if indoor temperature is 27 ℃, outdoor temperature is 30 ℃, and the preferred temperature that the user sets is 26 ℃, and then peak frequency is set at 52Hz.In addition, the difference of the preferred temperature that indoor temperature and user set is 1 ℃, so final frequency is confirmed as the 32Hz in the ROM table.That is to say that when the difference of the preferred temperature of setting as indoor temperature and user changed with 0.5 ℃ unit, preset frequency descended from peak frequency, so compressor is with this frequency work that has descended.For example, if peak frequency is set at 62Hz according to the indoor and outdoor temperature conditions, final frequency will change like this according to the temperature that sets (preferred temperature): 62Hz → 58Hz → 52Hz → 47Hz → 37Hz, and the inverted air conditioners compressor is with said frequencies work.
So according to the present invention, when the mode of operation of inverted air conditioners was energy-saving mode, the maximum operation frequency of compressor will be determined according to the indoor and outdoor temperature.After this, final operating frequency is determined by the difference and the maximum operation frequency of preferred temperature and indoor temperature.Then, the inversion air-conditioning is with final operating frequency work, so can reduce the power consumption of inverted air conditioners.
As mentioned above, according to inverted air conditioners electricity-saving operation method provided by the invention, peak frequency and final frequency are determined by indoor temperature, outdoor temperature and preferred temperature, can reduce the power consumption of inverted air conditioners thus.
In addition, according to inverted air conditioners electricity-saving operation method provided by the invention, make the scope of the indoor temperature of operating frequency change will set to such an extent that average indoor temperature is remained in 0.6 ℃ of excursion of measuring, the user can feel comfortably cool like this.
Because the present invention can implement with several forms, and do not deviate from its spirit or basic characteristics, so also should such understanding be arranged: the foregoing description to it, except as otherwise noted, do not limited, and should in the spirit and scope of appended claims defined, clearly be explained, so belong to all changes and improvements of claim scope by aforementioned any details, or be equal to all of this scope, all to be covered by appended claims.
