In order to facilitate understanding of the technical scheme of the present application, some technical terms related to the present application are described below.
The refrigerant is a working fluid that can be used to transfer heat energy and produce a refrigerating effect, and is generally used for cooling or heating in an air conditioner. The multi-connected air conditioner comprises a multi-connected air conditioner and a plurality of internal machines, wherein the refrigerant flows in the internal machines. Unlike the traditional one-to-one air conditioner, the multi-connected air conditioner may have the condition that part of indoor units are poor due to uneven refrigerant distribution.
In view of this, the present application provides an air conditioner control method applied to a processing apparatus. The processing device refers to a device with data processing capability, for example, may be a server, or a terminal device such as a desktop, a notebook, or a smart phone.
Specifically, the electronic device obtains the respective air inlet and outlet amounts of the plurality of internal machines and the respective air inlet and outlet enthalpy values of the plurality of internal machines, determines the respective heat exchange amounts of the plurality of internal machines according to the respective air inlet and outlet amounts of the plurality of internal machines and the respective heat exchange amounts of the plurality of internal machines, then determines the external machine power achievement ratio and the respective internal machine power achievement ratio of the plurality of internal machines according to the respective heat exchange amounts of the plurality of internal machines, determines a first internal machine with the highest capacity achievement ratio and a second internal machine with the lowest capacity achievement ratio from the plurality of internal machines, and adjusts the valve opening of the first internal machine when the capacity achievement ratio of the second internal machine is smaller than the external machine power achievement ratio under the target parameters. Therefore, whether the refrigerant distribution is uneven or not can be judged according to the capacity achievement conditions of the plurality of internal machines, and the valve opening of the first internal machine with the highest capacity achievement proportion is adjusted so as to balance the refrigerants of the plurality of internal machines.
Next, an air conditioner control method according to an embodiment of the present application will be described with reference to the accompanying drawings. The air conditioner is an air conditioner including a plurality of internal units.
Referring to a flowchart of an air conditioner control method shown in fig. 1, the method includes the steps of:
s102: the processing equipment obtains the respective air inlet and outlet quantity of the plurality of internal machines and the respective enthalpy value of the air inlet and outlet of the plurality of internal machines.
The air conditioner is an air conditioner with a plurality of internal machines, and the number of the internal machines indicated by the plurality of internal machines is more than or equal to 2.
The air conditioner has corresponding air inlet and outlet quantity under different modes, so that the air inlet and outlet quantity of the internal machine can be determined according to the mode of the internal machine. The modes of a plurality of internal machines of the same air conditioner can be different, and the corresponding air inlet and outlet amounts can be different.
The inlet air enthalpy values of the plurality of internal machines comprise inlet air enthalpy values and outlet air enthalpy values, the inlet air enthalpy values can be obtained according to inlet dry bulb temperatures and inlet wet bulb temperatures, and the outlet air enthalpy values can be obtained according to outlet dry bulb temperatures and outlet wet bulb temperatures.
Therefore, the dry bulb temperature and the wet bulb temperature of the plurality of internal machine inlets and the dry bulb temperature and the wet bulb temperature of the plurality of internal machine outlets can be obtained; and determining the enthalpy values of the inlet air and the outlet air of the plurality of internal machines according to the dry bulb temperature and the wet bulb temperature of the inlets of the plurality of internal machines and the dry bulb temperature and the wet bulb temperature of the outlets of the plurality of internal machines.
S104: the processing equipment determines the heat exchange quantity of the plurality of internal machines according to the air inlet and outlet quantity of the plurality of internal machines respectively and the enthalpy value of the air inlet and outlet of the plurality of internal machines respectively.
For any one internal machine, the heat exchange quantity of the internal machine is equal to the heat quantity of the inlet air of the internal machine subtracted by the heat quantity of the internal machine, wherein the heat quantity of the inlet air of the internal machine is equal to the product of the enthalpy value of the inlet air and the output air of the internal machine, and the heat quantity of the outlet air of the internal machine is equal to the product of the enthalpy value of the outlet air and the output air.
Therefore, the processing equipment can determine the heat exchange quantity of each internal machine according to the air inlet and outlet quantity and the enthalpy value of the air inlet and outlet of each internal machine.
S106: the processing equipment determines the power up-proportion of the external machine according to the heat exchange amount of the plurality of internal machines respectively and the power up-proportion of the internal machine of the plurality of internal machines respectively.
The processing equipment can determine the total heat exchange amount according to the heat exchange amounts of the plurality of internal machines, determine the heat exchange amount of the external machine according to the working condition of the air conditioner, and determine the energy proportion of the external machine according to the total heat exchange amount and the heat exchange amount of the external machine.
The total heat exchange amount is the sum of the heat exchange amounts of the plurality of internal machines, namely the total heat exchange amount is obtained by adding the heat exchange amounts of all the internal machines. The heat exchange quantity of the external machine can be determined according to the working conditions of the air conditioner, wherein the working conditions represent working modes, temperatures and the like. The processing equipment determines the energy proportion of the external machine through the total heat exchange amount and the heat exchange amount of the external machine.
The processing equipment can determine the respective calibrated heat exchange amount of the plurality of internal machines according to the working condition of the air conditioner, and then determine the internal machine power achievement proportion of the plurality of internal machines according to the respective heat exchange amount of the plurality of internal machines and the calibrated heat exchange amount of the plurality of internal machines.
Different working conditions of the air conditioner also correspond to different internal machine calibration heat exchange amounts, so that the corresponding calibration heat exchange amounts can be determined according to the working conditions of the air conditioner. For any one internal machine, the calibrated heat exchange amount can be determined according to the working condition of the air conditioner, and then the internal machine capacity of the internal machine can be obtained according to the division of the calibrated heat exchange amount by the calibrated heat exchange amount. Thus, the internal machine power of each of the plurality of internal machines can be obtained in proportion.
S108: the processing device determines a first internal machine with highest capability achievement proportion and a second internal machine with lowest capability achievement proportion from the plurality of internal machines.
In China, a first internal machine with the highest capability achievement proportion and a second internal machine with the lowest capability achievement proportion are selected according to the capability achievement proportion of the internal machines.
The second internal unit with the lowest capacity achievement ratio indicates that the internal unit may have less refrigerant.
S110: when the capability achievement proportion of the second internal machine is smaller than the external machine capability achievement proportion under the target parameter, the processing equipment adjusts the valve opening of the first internal machine.
The target parameter is a preset parameter, and may be a number smaller than 1 in general, for example, may be 0.85. When the capacity achievement proportion of the second internal machine is smaller than the capacity achievement proportion of the external machine by 0.85 times, the processing equipment adjusts the valve opening of the first internal machine.
The capability achievement proportion of the second internal machine being smaller than the external machine capability achievement proportion under the target parameter indicates that the refrigerant in the second internal machine is less in all internal machines, so that measures are required to be taken to balance the refrigerant. Therefore, the valve opening of the first inner machine with the highest capacity achievement proportion can be adjusted, specifically, the valve opening of the first inner machine is adjusted to be small, and when the valve opening of the first inner machine is adjusted to be small, the valve opening corresponding to the second inner machine can be automatically adjusted, so that the refrigerant is uniformly distributed.
Wherein, the state of the air conditioner includes both cooling and heating, and when the state of the air conditioner is heating, S110 includes:
and when the capability achievement proportion of the second internal machine is smaller than the capability achievement proportion of the external machine under the target parameter and the valves of the plurality of internal machines are all opened, adjusting the valve opening of the first internal machine.
In some cases, there may be less refrigerant in the air conditioner, resulting in a capacity achievement ratio of the second internal machine that is smaller than that of the external machine at the target parameter, so that it can be determined by the valve of the internal machine whether it is the cause of the refrigerant imbalance or the refrigerant total amount is smaller. In the heating state, when the valves of the plurality of internal machines are opened and the capacity achievement proportion of the second internal machine is smaller than the capacity achievement proportion of the external machine under the target parameter, the condition is that the refrigerant imbalance causes the capacity achievement proportion of the second internal machine to be smaller, and therefore the refrigerant can be adjusted by adjusting the valve opening of the first internal machine.
In the refrigeration mode, the method is characterized in that the valve opening of the second inner machine and the average inner machine valve opening are used, when the valve opening of the second inner machine is larger than the average inner machine valve opening, the fact that the second inner machine power is smaller due to unbalanced refrigerant is indicated, and therefore the refrigerant can be adjusted through the valve opening of the first inner machine.
In the cooling mode, the flow of the air conditioner control method may be as shown in fig. 2, and the method includes the following steps:
s202: the processing equipment acquires the respective air inlet and outlet quantity of the plurality of internal machines, the respective air inlet and outlet enthalpy values of the plurality of internal machines and the respective valve opening degrees of the plurality of internal machines.
S204: and the processing equipment determines the heat exchange quantity of the plurality of internal machines according to the respective air inlet and outlet quantity of the plurality of internal machines and the respective enthalpy value of the air inlet and outlet of the plurality of internal machines.
S206: the processing equipment determines the power up-scaling of the external machine according to the heat exchange capacity of the plurality of internal machines respectively and the power up-scaling of the internal machines of the plurality of internal machines respectively.
S208: the processing device determines a first internal machine with highest capability achievement proportion and a second internal machine with lowest capability achievement proportion from the plurality of internal machines.
S210: the processing device calculates an average internal machine valve opening according to the valve opening of each of the plurality of internal machines.
The present embodiment does not limit the execution sequence of S210 and S204 to S208.
S212: when the capability achievement proportion of the second internal machine is smaller than the capability achievement proportion of the external machine under the target parameter, and the valve opening of the second internal machine is larger than the average internal machine valve opening, the processing equipment adjusts the valve opening of the first internal machine.
Based on the description of the above, the embodiment of the application provides an air conditioner control method, which comprises the steps of obtaining the air inlet and outlet quantity of a plurality of internal machines respectively and the air inlet and outlet enthalpy value of the plurality of internal machines respectively, determining the heat exchange quantity of the plurality of internal machines respectively according to the air inlet and outlet quantity of the plurality of internal machines respectively, determining the energy achievement proportion of an external machine and the energy achievement proportion of the plurality of internal machines respectively according to the heat exchange quantity of the plurality of internal machines respectively, determining a first internal machine with the highest energy achievement proportion and a second internal machine with the lowest energy achievement proportion from the plurality of internal machines, and adjusting the valve opening of the first internal machine when the energy achievement proportion of the second internal machine is smaller than the energy achievement proportion of the external machine under a target parameter. Therefore, whether the refrigerant distribution is uneven or not can be judged according to the capacity achievement conditions of the plurality of internal machines, and the valve opening of the first internal machine with the highest capacity achievement proportion is adjusted so as to balance the refrigerants of the plurality of internal machines.
