Example 8
The embodiment exemplifies the practical application of the energy-saving device provided by the invention, and provides a further basis for the application of the energy-saving device.
The applicant respectively carries out a summer energy consumption test and a winter energy consumption test aiming at two working conditions of refrigeration and heating.
In order to eliminate the interference of weather change on the test, A, B rooms with the same floor are selected for comparison test, and A, B rooms all use two air conditioners with the same brand, the same model and the same production batch (American, KFR-26GW/WDAA3@, variable frequency). The applicant finds that even if the two air conditioners similar to each other are under the same operating condition and set temperature, when the two air conditioners are normally used, the energy consumption and the cooling (or heating) performance of the two air conditioners still have a certain difference, so that in the testing process, the applicant firstly needs to determine the relative capacities of the cooling (or heating) performance and the energy consumption of A, B rooms, therefore, the first stage of the testing is a double blank experiment, the air conditioners in the two rooms are not provided with the energy saving device provided by the invention, the two rooms keep the same environmental condition, the air conditioner parameters are set to be the same, the air conditioners in the two rooms are kept to continuously operate for 24 hours, and the energy consumption of the rooms is taken at a fixed time every morning and evening and the temperature in the rooms is recorded. Comparing A, B the refrigerating (or heating) performance and energy consumption of two air conditioners in room, determining the energy consumption difference of two air conditioners when the air conditioners reach the same or similar refrigerating (or heating) effect, so as to determine the relative energy consumption condition of the two air conditioners to be tested.
The second stage test is an installation period experiment, the energy-saving device provided by the invention is installed at air inlets of an indoor unit (necessary) and an outdoor unit (optional) of an air conditioner in a room A, and no product is installed in a room B. The experimental conditions and experimental procedures are the same as those in the first stage.
By comparing the temperature conditions in the first-stage room and the second-stage room, if the temperature in the first-stage room and the temperature in the second-stage room do not change obviously, the refrigeration (or heating) performance of the two air conditioners in the first-stage room and the second-stage room are not fluctuated or abnormal, and therefore the contrast of the energy consumption difference of the two air conditioners obtained in the two stages is determined to be comparable.
And finally, comparing the energy consumption difference of the two air conditioners in the first stage A, B room and the second stage A, B room, and calculating to obtain the energy saving rate of the room A after the product is installed. The calculation method is as follows:
the calculation formula is as follows:

Figure BDA0002123493000000072
in the formula: alpha is the energy saving rate; k is an energy consumption adjusting parameter of the two air conditioners; a. the1、A2Respectively the hourly energy consumption (unit: kWh/H) of the first-stage air conditioner and the second-stage air conditioner in the room A and B1、B2The energy consumption (unit: kWh/H) of the first and second air conditioners in the room B per hour is respectively.
The summer energy consumption test plan and the installation of the energy saving device in the room are shown in table 1.

Note: the blank is that the energy-saving device provided by the invention is not installed, the installation is that the energy-saving device is installed, and in the test, the energy-saving device is installed at the air inlet of the indoor unit and the air inlet of the outdoor unit.
In the summer energy consumption test, the A, B two room air conditioners start the refrigeration mode, the air conditioner set temperature is 20 ℃, the wind speed is set to be 60%, the air is automatically swept, and other parameters adopt default settings in the refrigeration mode.
The thermo-hygrometers are placed at positions outside the window and used for monitoring indoor temperature and humidity conditions and the working environment of the outdoor unit of the air conditioner. The temperature data is obtained by a hygrothermograph arranged outside the window and is used for reflecting the working environment of the outdoor unit of the air conditioner. The outdoor and indoor temperature test results are shown in fig. 4-a and 4-B, respectively. As can be seen from FIG. 4-B, the coincidence of the indoor temperature curves of the two test rooms during the test period is good, and the temperature difference does not exceed 0.4 ℃. The air conditioners in the two test rooms can achieve similar refrigeration effects under the same setting parameters, so that the energy consumption conditions of the two air conditioners have strong comparability.
Because the testing time lengths are slightly different, for more reasonable and scientific analysis, the subject group divides the total energy consumption of the testing section by the testing time length to obtain the unit consumption of the air conditioner of the test, and then the unit consumption comparison mode is adopted for analysis. The unit consumption difference ratio variation graph is shown in fig. 4-C, and it can be seen from the graph that after the air conditioner of the room a is installed in the air conditioner of the invention in 11 days of 9 months, the unit consumption difference ratio has a significant downward trend, that is, the energy-saving device of the invention has a significant energy-saving effect.
