Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
As shown in fig. 1, in order to solve the problem that the electric quantity sharing method of the charging system of the multi-split central air conditioner in the prior art is not accurate enough, the present invention provides an electric quantity sharing method of a multi-split central air conditioner, which comprises the following steps:
s100, acquiring the power consumption of the air conditioning system in all power consumption periods with different power consumption unit prices in one day.
And S200, respectively acquiring the power consumption of each user indoor unit in each power consumption time period.
And S300, respectively obtaining the electric quantity sharing coefficient of each user indoor unit in each electricity utilization period.
And S400, calculating the electric quantity to be distributed of each user indoor unit in each electricity utilization period based on the electric consumption of the air conditioning system in all electricity utilization periods with different electricity rates in one day, and the electric consumption and the electric quantity distribution coefficient of each user indoor unit in each electricity utilization period.
Although the foregoing embodiments have described various steps in the above sequential order, those skilled in the art will understand that, in order to achieve the effect of the present embodiments, the different steps need not be executed in such an order, and may be executed simultaneously (in parallel) or in an inverse order, and these simple variations are all within the scope of the present invention. For example, step S100 to step S300 may be performed simultaneously, or step S200 or step S300 may be performed first, and then step S100 may be performed. In short, the power consumption of the air conditioning system, the power consumption of each user indoor unit and the power allocation coefficient of each user indoor unit can be acquired in all power consumption periods with different electricity rates in one day.
In the method for sharing electric quantity of the multi-split central air conditioner provided by the embodiment, the electric quantity of the air conditioning system and all the user indoor units is respectively counted in all the electricity utilization periods with different electricity rates in one day. The power consumption of the air conditioning system refers to the total power consumption of the inner unit and the outer unit of the multi-split central air conditioner.
On one hand, the power consumption of each user indoor unit in different power consumption periods is different, and on the other hand, the unit price of the power charge in different power consumption periods is different, so in order to more accurately distribute the power of the multi-split central air conditioner, the power consumption of the air conditioning systems needs to be counted in different power consumption periods, and the power distribution is carried out according to the power distribution coefficients of the different user indoor units in each power consumption period.
The electricity usage periods of the present embodiment, in which the electricity rates are different, may be specifically divided according to fluctuations in electricity rates of the local power supply system during the day. For example, the electricity consumption periods of the north China power grid are divided as follows: the peak time period is 9h, the valley time period is 7h, and the ordinary time period is 8 h. The division condition of the power utilization period of the Guangxi power grid is as follows: the daily peak period was 7: 00-1: 00, 19: 00-23: 00; the usual time period is 11: 00-19: 00; the trough period was 23: 00-day 7: 00. the division condition of the power utilization period of the northeast power grid is as follows: in the peak period: 8: 00-11: 00, 11: 00-21: 00; in the valley period: 22: 00-day 5: 00; the rest of the time is the usual time period.
When the multi-split central air conditioner is used for distributing the electric quantity, objective factors with different unit prices of the electric charges in different electricity consumption periods are fully considered, the electric quantity and the electric charges are more accurately distributed, the load rate and the equipment utilization rate of a power grid are further improved, and the purposes of controlling peak load, fully utilizing the low-ebb electric quantity of the power grid and comprehensively improving the economic benefits of the whole society are achieved.
The electric quantity sharing method for the multi-split central air conditioner provided by the embodiment obtains the electric quantity to be shared by each user indoor unit in each electricity utilization period based on the electric consumption of the air conditioning system, the electric consumption of each user indoor unit and the electric quantity sharing coefficient which are respectively obtained in all the periods with different electricity rates in one day. The electric quantity sharing method of the embodiment considers the difference of the unit price of the electric charges in different periods and the difference of the electric quantity sharing coefficient of each user indoor unit when sharing the electric quantity of the multi-split central air conditioner, so that the obtained electric quantity to be shared by each user indoor unit in each electricity utilization period is more accurate, and the actual electricity utilization condition of each user indoor unit can be reflected more truly.
In a preferred embodiment of the above electricity sharing method for the multi-split central air conditioner, the step S100 of obtaining the electricity consumption of the air conditioning system in all electricity consumption periods with different electricity rates in a day includes: acquiring the reading of an electric meter of the air conditioning system at the beginning of each electricity utilization period; acquiring the reading of an electric meter of the air conditioning system at the end of each electricity utilization period; and calculating the difference between the reading of the electric meter of the air conditioning system at the end of each electricity utilization period and the reading at the beginning of each electricity utilization period as the electricity consumption of the air conditioning system in each electricity utilization period.
For example, a time trigger may be used in the billing system of the central air conditioner to trigger the system to read the readings of the air conditioning system's electricity meter at the beginning and at the end of the different electricity usage periods. The system may record the power consumption of each power usage period in time periods.
In a preferred embodiment of the method for apportioning electric power of a multi-split central air conditioner, the step S200 of respectively obtaining the electric power consumption of each user indoor unit in each power consumption period includes: obtaining the indoor unit electric heating power consumption of each user indoor unit in each power consumption time period; acquiring the power consumption of an indoor unit fan of each user indoor unit in each power consumption time period; and calculating the sum of the electric power consumption of the internal electric heating and the electric power consumption of the internal machine fan as the electric power consumption of each user indoor machine in each power consumption time interval.
Exemplarily, the most important factors influencing the power consumption of the indoor unit of the user are the power consumption of the electric heating of the indoor unit and the power consumption of the fan of the indoor unit, the power consumption of the electric heating determines the temperature of the air flow provided by the air conditioner, and the power consumption of the fan of the indoor unit determines the air speed of the air conditioner; the sum of the power consumption of the internal machine electric heating and the power consumption of the internal machine fan is directly used as the power consumption of each user indoor machine in each power consumption time interval, and the method is a simple and effective method for calculating the power consumption of each user indoor machine in each power consumption time interval.
In a preferred embodiment of the above method for apportioning electric power of a multiple split air conditioner, the method for obtaining the electric power consumption of indoor unit electric heating of each user indoor unit in each electric power consumption period includes: acquiring the actual working time of the indoor unit electric heating of each user in each electricity utilization period; acquiring the actual power of indoor unit electric heating of each user indoor unit in each electricity utilization period; and calculating the product of the actual working time of the electric heating of the internal machine and the actual power of the electric heating of the internal machine to be used as the electric power consumption of the electric heating of the internal machine.
For example, in different power consumption periods, the indoor unit of the user has different times and different temperatures for turning on the indoor unit electric heating function, so the product of the actual working time of the indoor unit electric heating and the actual power of the indoor unit electric heating needs to be used as the power consumption of the indoor unit electric heating. When the accumulated heating time of the internal machine electric heating in a certain power utilization period is calculated, the internal machine electric heating starts to time through a trigger triggering system when the internal machine electric heating is started and closed, and finally the system adds the electric heating time in the certain power utilization period to be used as the actual power utilization time of the internal machine electric heating.
In a preferred embodiment of the above electricity sharing method for a multi-split central air conditioner, the obtaining of the electricity consumption of the indoor unit fan of each user indoor unit in each electricity consumption period includes: acquiring the actual working time of each user indoor unit in each power consumption time interval; acquiring the actual power of each indoor unit of each user in each power consumption time interval; and calculating the product of the actual working time of the inner fan and the actual power of the inner fan to be used as the power consumption of the inner fan.
In a preferred embodiment of the above electricity quantity sharing method for a multi-split central air conditioner, acquiring actual power of each indoor unit of a user in each electricity consumption period includes: acquiring the wind speed coefficient of an inner fan in each user indoor unit; obtaining the rated power of an internal fan in each user indoor unit; and calculating the wind speed coefficient of the inner fan and the rated power of the inner fan to serve as the actual power of the inner fan.
For example, the wind speeds of the fans of the indoor units of users are different, and the actual powers of the indoor fans are also different, for example, when the modes of the indoor fans include various modes such as automatic mode, low wind mode, medium wind mode, high wind mode, and the like, the actual power of the indoor fan is higher in a high wind state. Therefore, when the actual electricity consumption of the fan is calculated, different states of the fan trigger the system to record the duration time of the state of the fan through the trigger.
The wind speed coefficient is related to the actual wind speed of the inner fan when the inner fan works, and the higher the wind speed is, the larger the wind speed coefficient is, and the larger the actual power of the inner fan is. For example, in a high wind condition, the wind speed coefficient is 1.45; in a stroke state, the wind speed coefficient is 1.2; in the low wind regime, the wind speed coefficient is 1.
In a preferred embodiment of the above electricity sharing method for the multi-split central air conditioner, in step S300, a calculation formula of the electricity sharing coefficient of each user indoor unit in each electricity utilization period is obtained as follows:
k is a switch state parameter of each user indoor unit in each power utilization period; when the indoor unit of the user is started, K is 1; when the indoor unit of the user is closed, K is 0;
m is a mode state parameter of each user indoor unit in each power utilization period, and M is 1 in a refrigeration mode; under the heating mode, M is 1; in the dehumidification mode, M is 1; in the air supply mode, M is 0; m ═ 1 in the automatic mode;
f is a wind speed state parameter of each user indoor unit in each power utilization period, and in the automatic mode, F is 0.95; in low wind mode, F ═ 0.87; in stroke mode, F ═ 0.95; in high wind mode, F ═ 1.00;
s is a capacity demand state parameter of each user indoor unit in each power consumption time period, and the numerical range of the capacity demand state parameter is 0-1.5; for example, the value range of the capacity requirement value of the user indoor unit with the nominal refrigerating capacity below 2600W is 0.7-0.9; the value range of the capacity requirement value of the user indoor unit with the nominal refrigerating capacity within the range of 2600W-3500W is 0.9-1.1; the value range of the capacity requirement value of the user indoor unit with the nominal refrigerating capacity within the range of 3500W-5000W is 1.1-1.5, and the like.
P is a matching state parameter of each user indoor unit in each power consumption period, and the numerical value of the matching state parameter is 0.6/0.8/1/1.2/1.5/1.7/2/2.5/3/3.2/4/5/6/8/10/15 and the like;
besides, K M F S P is the indoor unit parameter of each user indoor unit in each power utilization time interval;
the sum of the indoor unit parameters of all the indoor units of the users in each power utilization period is shown, and n is the total number of the indoor units of the users of the multi-split central air conditioner.
Of course, the specific values of the parameters are all reference values of the parameters of the user indoor units of a certain type of central air conditioner, and the specific values of different central air conditioners can be adjusted according to specific conditions.
As can be seen from the above description, in the present embodiment, when the electric quantity sharing coefficient of the user indoor unit is calculated, various parameters in the actual operating state of the user indoor unit are fully considered, so that the electric quantity sharing coefficient of the user indoor unit of the present embodiment is calculated more accurately, and the sharing of the electric quantity is more fair.
In a preferred embodiment of the method for allocating electric energy to a multi-split central air conditioner, in step S400, before calculating an electric energy to be allocated to each of the user indoor units in each of the electricity consumption periods, the method further includes: and calculating the difference between the power consumption of the air conditioning system in each power utilization period and the sum of the power consumption of all the user indoor units in each power utilization period as the power consumption to be distributed of the air conditioning system in each power utilization period.
For example, the power consumption to be allocated by the air conditioning system in each power consumption period in the embodiment includes other power consumption besides the power consumption of the indoor unit electric heating and the power consumption of the indoor unit fan of the user indoor unit, wherein the power consumption is mainly of the outdoor unit.
In a preferred embodiment of the method for allocating electric energy to a multi-split central air conditioner, the step S400 of calculating an electric energy to be allocated to each user indoor unit in each power consumption period includes: and calculating the product of the power consumption to be distributed and the electric quantity sharing coefficient to be used as the electric quantity to be distributed of each user indoor unit in each power consumption period.
For example, in the embodiment, when the amount of electricity to be allocated to each user indoor unit in each electricity consumption period is calculated, the electricity allocation coefficient is used as the weight of the amount of electricity to be allocated to each user indoor unit, and the electricity allocation coefficient of the embodiment fully considers various parameters in the actual working state of the user indoor unit, so that the proportion of different user indoor units to be respectively occupied in the electricity allocation can be more truly reflected, and the result of the electricity allocation is closer to the real situation and more accurate.
In a preferred embodiment of the method for sharing the electric quantity of the multi-split central air conditioner, the electricity utilization period includes an electricity utilization peak period, an electricity utilization valley period and an electricity utilization ordinary period.
For example, the different electricity utilization periods at present generally include three periods, namely an electricity utilization peak period, an electricity utilization valley period and an electricity utilization ordinary period, each electricity utilization period in a day can be continuous or discontinuous, and a plurality of electricity utilization peak periods and electricity utilization valley periods can be included in a day. For example, there may be two peak hours of electricity usage, 7 am to 11 am and 19 pm to 23 pm.
It can be understood by those skilled in the art that, although the above-mentioned embodiment of the method for apportioning electric quantity of a multi-split central air conditioner is described by taking the sum of the electric consumption of the internal electric heating and the electric consumption of the internal fan as the electric consumption of the user indoor unit in each electricity consumption period as an example, this is not intended to limit the protection scope of the present application, and those skilled in the art can adjust the method based on the actual application scenario as long as the adjustment is satisfied to obtain a more accurate electric consumption of the user indoor unit in each electricity consumption period.
For example, in another alternative embodiment, the user indoor unit further includes an electronic expansion valve, and the electronic expansion valve consumes power during the opening degree adjustment process. Therefore, the actual power and the power consumption of the electronic expansion valve can be also considered when calculating the power consumption of the user indoor unit in each power consumption period, so that the power consumption calculation of the user indoor unit is more accurate.
For example, in another alternative embodiment, the power consumption of the internal electric heating unit and the power consumption of the internal fan unit may be obtained by directly measuring the actual power consumption of the whole indoor unit of each user in a certain power consumption period, in addition to the actual power consumption multiplied by the actual operating time.
For example, in another alternative embodiment, the electric quantity sharing coefficient can be calculated directly by the proportion of the number of internal machines; or, a ratio of the power consumption of each user indoor unit in each power consumption period to the sum of the power consumption of all the user indoor units in each power consumption period may be used as the power allocation coefficient; furthermore, the mode state parameter M and the wind speed state parameter F in the electric quantity sharing coefficient can be classified in more detail, so that the electric quantity sharing coefficient of the indoor unit of the user can be calculated more accurately.
For example, in another alternative embodiment, the sum of the power consumption of each user indoor unit in each power consumption period and the power amount to be shared may be used as the final power consumption of the user indoor unit in the power consumption period, and recorded in each user indoor unit or in a memory of an electric meter, so as to be conveniently obtained by electric power personnel at any time.
For example, in another alternative embodiment, the final power consumption amount of each power consumption period may be multiplied by the unit price of the power consumption period to obtain the power consumption generated by the indoor unit of the user in the power consumption period. The total price of the electricity charges of the user indoor unit in one day is equal to the sum of the electricity charges of all electricity utilization periods of the user indoor unit in one day.
It should be noted that although the detailed steps of the method of the present invention have been described in detail, those skilled in the art can combine, separate and change the order of the above steps without departing from the basic principle of the present invention, and the modified technical solution does not change the basic concept of the present invention and thus falls into the protection scope of the present invention.
