The present embodiment illustrates to the practical application of energy saver provided by the invention, provides for its application further
Foundation.
Applicant has carried out summer energy consumption testing and winter energy consumption testing for freezing and heating two kinds of operating conditions respectively.
In order to exclude interference of the Changes in weather to test, two room A, B that same floor is had chosen in test is compareed
Test, the room A, B use same brand, same model, same production batch (beautiful, KFR-26GW/WDAA3@, frequency conversion)
Two air-conditionings.It is found by the applicant that even so similar two air-conditionings are under identical service condition and set temperature, normal use
When, there are still certain differences for performance for energy consumption and refrigeration (or heating), so applicant is needed first to A, B during the test
Refrigeration (or heating) performance of two air-conditionings in room and the relative ability of energy consumption are determined, therefore the first stage tested is double
Blank assay, the air-conditioning in two rooms do not install energy saver provided by the invention, and two rooms keep identical environment item
Part, and air-conditioning parameter setting is identical, two room air conditioners keep 24 hours continuous operations, each once in the set time daily morning and evening
It copies and takes room energy consumption and record temperature in room.By refrigeration (or heating) performance and energy consumption that compare two air-conditionings in the room A, B
Situation determines that the energy consumption difference of two air-conditionings determines two with this when air-conditioning reaches same or similar refrigeration (or heating) effect
The relative energy consumption situation of the refrigeration (or heating) of platform air-conditioning to be measured.
Second stage test is to test the installation phase, and energy saver provided by the invention is installed on to the interior of A room air conditioner
Machine (must fill) and outdoor unit (choose to install) air inlet, and B does not install product in room.Experiment condition, experimental procedure are and the first stage
It is identical.
By temperature conditions in the first and second stage room of comparison, if there is not significant change in temperature in two stages room,
I.e. it is believed that refrigeration (or heating) performance of two air-conditionings does not occur fluctuating or extremely, thereby determine that within the first and second stage
Two stages, resulting air conditioning energy consumption difference had comparability.
Finally the energy consumption difference of the first and second two, the room stage A, B air-conditioning is compared, the room A can be obtained by, which being computed, is pacifying
Fractional energy savings after filling product.Calculation is as follows:
Calculation formula are as follows:
In formula: α is fractional energy savings；K is the energy consumption adjustment parameter of two air-conditionings；A1、A2Respectively the first and second stage of the room A air-conditioning
Energy consumption (unit: kWh/H) per hour, B1、B2Respectively the first and second stage of the room B air-conditioning energy consumption (unit: kWh/H) per hour.
The installation situation of energy saver is as shown in table 1 in summer energy consumption testing plan and room.

Note: " blank ", which refers to, does not install energy saver provided by the invention, and " installation " refers to installation energy saver, this test
In, energy saver is installed on indoor unit air inlet and outdoor unit air inlet.
In summer energy consumption test, two room air conditioner of A, B opens refrigeration mode, and it is 20 DEG C that temperature, which is arranged, in air-conditioning, and wind speed is set
60% is set, automatic swing flap, other parameters use the default setting under refrigeration mode.
Hygrothermograph is placed in position outside window, to monitor the environment of indoor temperature and humidity situation and air-conditioner outdoor unit work.
Temperature data is obtained by the Hygrothermograph placed outside window, to embody the environment of air-conditioner outdoor unit work.Outdoor and room temperature
Test result is respectively as shown in Fig. 4-A, 4-B.By Fig. 4-B it is found that test during two test room room temperature curve co-insides
Well, the temperature difference is no more than 0.4 DEG C.Illustrate that the air-conditioning of two test rooms under similarly setting parameter, can reach similar refrigeration
Effect, therefore the energy consumption of two air-conditionings has very strong comparability.
Since the duration of test slightly has difference, for more rationally science analysis, seminar by the total energy consumption of test section divided by
Length of testing speech obtains the air-conditioning unit consumption of this test, is then analyzed by the way of unit consumption comparison.Unit consumption difference is than becoming
Change figure as shown in Fig. 4-C, have as seen from the figure, the room A is after September air-conditioning on the 11st installs energy saver provided by the invention, unit consumption
There is apparent downward trend in difference ratio, i.e., energy saver provided by the invention shows apparent energy-saving effect.
