Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus detailed descriptions thereof will be omitted.
The terms "a," "an," "the," "said" are used to indicate the presence of one or more elements/components/etc., the terms "comprising" and "having" are intended to mean that there may be additional elements/components/etc. in addition to the listed elements/components/etc.
Example 1
To solve the above problems, according to an aspect of the present invention, as shown in fig. 1, there is provided a rental air conditioner price evaluation method considering air conditioner energy consumption, comprising:
S11, obtaining the air outlet quantity of the air conditioner based on the relation between the air outlet speed of the air conditioner and the air outlet quantity of the air conditioner, and obtaining the refrigerating capacity of the air conditioner based on the product of the air outlet quantity, the working time, the difference between the air outlet temperature and the fixed temperature threshold value of the air conditioner;
for example, the outlet wind speed of the air conditioner can be obtained by measuring the outlet wind speed of the air outlet of the air conditioner, and a fixed calculation formula exists between the outlet wind speed and the air outlet on the basis, and the formula generally exists in the specification of a manufacturer.
For a specific example, the wind speed and wind volume conversion formula is that L=3600×FXV (F-wind gap ventilation area m 2, V-measured wind gap average wind speed (m/s)).
The air quantity is the product of the air speed V and the air channel sectional area F. Since the wind speed of the large fan can be accurately measured by the anemometer, the wind volume calculation is simple, and the wind volume can be calculated by directly using the formula q=vf. Wherein Q is the single air quantity of the selected fan model, V is the field volume, and F is the cross-sectional area of the air duct.
The air quantity is the most important index for measuring the heat dissipation capacity of the air-cooled radiator. It is apparent that the larger the air volume, the higher the heat dissipation capacity of the radiator. This is because the heat capacity of air is constant, and the larger the air volume is, the more heat in the air can be taken away in unit time. Of course, the heat radiation effect and the airflow pattern are related to the same airflow.
For a specific example, the air output is 20, the working time is 2 hours, the air outlet temperature is 18 ℃, and the refrigeration output of the air conditioner is obtained by multiplying 20 by 2 and multiplying (30-18) by 480, wherein 30 is a set fixed temperature.
S12, obtaining the charge price of the air conditioner based on the charge standard of the refrigerating capacity output by the air conditioner and the unit refrigerating capacity;
For example, if the cooling capacity is 30 and the charging standard of the unit cooling capacity is 2 yuan, the charging price of the air conditioner is 60 yuan.
S13, correcting the charging price of the air conditioner based on the energy efficiency level of the air conditioner to obtain the basic charging price of the air conditioner;
For example, the air conditioning efficiency level, i.e., the energy efficiency ratio of an air conditioner, is the ratio of the rated cooling capacity to the rated power consumption. In general, how much cold air is generated by consuming as much electricity is an important parameter for measuring the performance of an air conditioner. The national standard of the energy efficiency ratio of air-conditioning products is promulgated in 2005, and the energy efficiency ratio of the common air conditioner is divided into five grades.
For example, the energy efficiency level of the air conditioner can be divided into corresponding discount rates, wherein the energy efficiency is higher, the discount rate is smaller than 1, the energy efficiency is lower, and the discount rate is larger than 1, or a discount rate calculation formula is built according to the energy efficiency level of the air conditioner, so that the discount rate of the air conditioner is obtained.
S14, judging whether the single accumulated working time of the air conditioner is larger than a first time threshold, if so, entering a step S15, and if not, taking the basic charging price of the air conditioner as a final charging price;
for example, if the single cumulative operating time of the air conditioner is 10 hours and the first time threshold is 8 hours, the method proceeds to step S15, and if the single cumulative operating time is 6 hours and the first time threshold is 8 hours, the basic charging price of the air conditioner is taken as the final charging price.
S15, judging whether the indoor temperature is smaller than a first temperature threshold value, if so, entering a step S16, and if not, taking the basic charging price of the air conditioner as a final charging price;
S16, correcting the basic charging price of the air conditioner based on the single accumulated working time of the air conditioner and the indoor temperature to obtain a corrected price, and taking the corrected price as the final charging price of the air conditioner.
Specifically, for example, a correction amount is constructed by the single cumulative operating time of the air conditioner and the indoor temperature, and a corrected price is obtained based on the product of the correction amount and the basic charging price, or the correction amount is obtained by using the single cumulative operating time of the air conditioner and the indoor temperature as input amounts by a correction amount prediction model.
The charging of the air conditioner is realized based on the refrigerating capacity of the air conditioner, so that the charging standard of the air conditioner becomes more accurate, the inaccurate technical problem caused by adopting electric energy charging is avoided, and the final charging of the air conditioner can more accurately reflect the actual workload.
The charging price of the air conditioner is corrected based on the energy efficiency level of the air conditioner, so that the charging of the air conditioner can be related to the energy consumption of the air conditioner, further less electric energy consumption and waste are promoted, the intensity of carbon emission is reduced, and the method has a certain environmental value.
The first temperature threshold value and the first time threshold value are set, so that the charging price of the air conditioner is related to the single accumulated working time and the indoor temperature of the air conditioner, and on the basis, the basic charging price of the air conditioner is corrected through the single accumulated working time and the indoor temperature of the air conditioner to obtain the corrected price, thereby further promoting the reduction of the electric energy consumption and the carbon emission intensity on the basis of ensuring better comfort level.
In another possible embodiment, the relation between the outlet wind speed of the air conditioner and the air output of the air conditioner is determined according to the specification mark of the manufacturer of the air conditioner.
In another possible embodiment, the specific steps for obtaining the refrigerating capacity of the air conditioner are as follows:

for example, if the temperature of the air outlet is 30 degrees, the outdoor temperature is 30 degrees, and the first difference threshold is 10 degrees, the air conditioner is judged to be in an abnormal state.
S22, reading the outlet wind speed of the air conditioner, judging whether the outlet wind speed of the air conditioner is smaller than a first wind speed threshold value, if so, judging that the air conditioner is in an abnormal state, not charging the air conditioner, and if not, entering step S23;
For example, if the outlet wind speed is 1m/s, and if the first wind speed threshold is 2m/s, the air conditioner is judged to be in an abnormal state, and charging of the air conditioner is not performed.
S23, obtaining the refrigerating capacity of the air conditioner based on the product of the air outlet quantity, the working time and the difference between the air outlet temperature and the fixed temperature threshold value.
The air conditioner in an abnormal state is eliminated by judging the difference between the air outlet temperature and the outdoor temperature and the outlet wind speed of the air conditioner, so that the technical problem of wrong charging caused by the damage of the air conditioner is further reduced, and the charging accuracy and reliability are further promoted.
In another possible embodiment, the first difference threshold is determined according to an outdoor temperature, and the first wind speed threshold is determined according to 30 percent of a set wind speed of a lowest gear of the air conditioner.
In another possible embodiment, the specific steps of constructing the basic charging price of the air conditioner are as follows:
S31, judging whether the energy efficiency level of the air conditioner is one level, if so, multiplying the charging price of the air conditioner by an environment compensation coefficient smaller than 1 to serve as the basic charging price of the air conditioner, and if not, entering step S32;
for a specific example, the environmental compensation coefficient is 0.98.
S32, judging whether the energy efficiency level of the air conditioner is two-level, if so, taking the charging price of the air conditioner as the basic charging price of the air conditioner, and if not, entering step S33;
s33, correcting the charging price of the air conditioner based on the energy efficiency grade of the air conditioner to obtain the basic charging price of the air conditioner.
By adopting different charging modes according to the energy efficiency level of the air conditioner, the scientificity and the accuracy of charging are further improved, on the basis, the charging of the air conditioner is further promoted, the air conditioner with higher energy efficiency level can be favored, and the carbon emission and the computer consumption are reduced.
In another possible embodiment, the calculation formula of the basic charging price of the air conditioner is:
Wherein D is the energy efficiency grade of the air conditioner, the value range is 3,4 and 5, J 2 is the charging price of the air conditioner, K 1、K2 is a constant, the value range is 0 to 1, and the dynamic adjustment is specifically carried out according to the purchase price of the air conditioner.
