Fig. 1 is a flowchart of a method for determining a charging capacity according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
s1, acquiring the cold charging capacity of the cold storage plate in unit time.
Specifically, the amount of cold charge per unit time of the cold storage plate can be obtained by various methods.
The first method comprises the following steps: the amount Of cold charged into the cold storage plate can be calculated by obtaining the refrigeration power, the refrigeration efficiency COP (energy efficiency ratio), the refrigeration empirical Coefficient (which can be understood as a conversion Coefficient, that is, the efficiency Of converting the actual amount Of cold into the amount Of cold charged into the cold storage plate) and the refrigeration duration Of the compressor. And then the cold charging amount per unit time of the cold storage plate can be obtained according to the cold charging amount and the cold charging duration which are obtained by calculation and charged in the cold storage plate.
And the second method comprises the following steps: the latent heat value of the cold storage material in the cold storage plate (the latent heat value is the inherent attribute of the cold storage material, different cold storage materials have different latent heat values, and the latent heat value, the mass of the cold storage material and the refrigerating time length can be obtained through experiments) can be obtained through obtaining, and therefore the refrigerating capacity charged in the cold storage plate can be obtained through calculation. And then the cold charging amount per unit time of the cold storage plate can be obtained according to the cold charging amount and the cold charging duration which are obtained by calculation and charged in the cold storage plate.
In an embodiment of the present invention, another method is adopted, which may specifically be as shown in fig. 2, and includes the following steps:
and S11, acquiring the temperature difference value between the inlet and the outlet of the cold charging pipe at the current moment.
The inlet and the outlet of the cold charging pipe can be respectively provided with a thermometer, and the temperature value of the inlet and the temperature value of the outlet of the cold charging pipe are measured, so that the temperature difference value of the inlet and the outlet is calculated.
And S12, acquiring the mass of the refrigerating medium in unit time.
In one embodiment of the invention, a flow meter can be used to measure the cold charge flow rate of the cold charge process and then determine the coolant mass per unit time from the cold charge flow rate. Specifically, the coolant density is known and the coolant mass per unit time is determined by multiplying the coolant density by the cold charge flow rate.
And S13, acquiring a cold quantity parameter.
The cold quantity parameter is related to at least one of the concentration of the secondary refrigerant, the heat exchange area of the cold storage plate, the length of the cold charging circulation pipeline, the length of the cold charging pipe outside the cold storage box and the pressure loss of the joint.
And S14, determining the cold charging capacity in unit time according to the temperature difference value between the inlet and the outlet of the cold charging pipe at the current moment, the mass of the secondary refrigerant in unit time and the cold parameter.
After the temperature difference value between the inlet and the outlet of the cold charging pipe at the current moment, the mass of the secondary refrigerant in unit time and the cold quantity parameter are obtained, the cold charging quantity in unit time can be determined according to the temperature difference value between the inlet and the outlet of the cold charging pipe at the current moment, the mass of the secondary refrigerant in unit time and the cold quantity parameter. Specifically, the specific heat of the secondary refrigerant is known, and the cold charging capacity in unit time is calculated by multiplying the specific heat of the secondary refrigerant by the temperature difference value between the inlet and the outlet of the cold charging pipe at the current moment, then multiplying the specific heat of the secondary refrigerant by the mass of the secondary refrigerant in unit time and finally multiplying the mass by the cold capacity parameter.
And S2, acquiring the cold charging starting time and the current time of the cold storage plate.
The cold charging starting time and the current time of the cold storage plate can be recorded by instruments such as a timer.
And S3, determining the cold charging amount corresponding to the current time according to the cold charging amount in unit time, the cold charging starting time and the current time.
After the cold charging amount, the cold charging starting time and the current time in unit time are obtained, the cold charging amount corresponding to the current time can be determined according to the cold charging amount, the cold charging starting time and the current time in unit time. Specifically, the charging capacity corresponding to the current time (the charged capacity from the charging start time to the current time) can be calculated by the formula one.
The formula I is as follows: the cold charge amount = cold charge amount per unit time corresponding to the current time (current time-cold charge start time)
According to the method for determining the cold charging capacity, the cold charging capacity per unit time of the cold storage plate is obtained, the cold charging starting time and the current time of the cold storage plate are obtained, and then the cold charging capacity corresponding to the current time is determined according to the cold charging capacity per unit time, the cold charging starting time and the current time, so that the cold charging capacity of the cold storage box can be accurately quantized, and the cold charging capacity of the cold storage box can be intelligently managed.
In addition, in another embodiment, as shown in fig. 3, the method for determining the charging capacity may further include the steps of:
and S4, acquiring the latent heat value of the cold accumulation plate.
And S5, determining the time required by cold charging according to the latent heat value, the cold charging amount in unit time and the cold charging amount corresponding to the current moment.
Specifically, the time required for cooling can be calculated according to the formula two.
The formula II is as follows: time required for cooling = (latent heat value-cooling amount corresponding to current moment)/cooling amount per unit time
According to the method for determining the cold charging amount, provided by the embodiment of the invention, the cold charging required time is determined according to the latent heat value, the cold charging amount in unit time and the cold charging amount corresponding to the current moment by acquiring the latent heat value of the cold storage plate, so that the cold charging required time can be accurately determined, and the intelligent management of cold charging is realized.
In addition, in another embodiment, as shown in fig. 4, the method for determining the amount of cold charging may further include the steps of:
and S6, determining the percentage of the charged cold according to the latent heat value, the unit time of the charged cold quantity, the temperature difference value between the inlet and the outlet of the cold charging pipe at the current moment, the cold charging starting moment and the current moment.
Specifically, the percentage of cold charged may be calculated according to equation three.
The formula III is as follows: percentage of cold charge = (current time-start time of cold charge) (temperature difference between inlet and outlet of cold charge pipe/standard temperature difference between inlet and outlet of cold charge pipe at current time) ((cold charge/latent heat value per unit time))
The standard temperature difference between the inlet and the outlet of the cold charging pipe can be the standard temperature difference of the experiment, and can also be the average temperature difference.
According to the method for determining the cooling capacity, the percentage of the cooling capacity already charged can be accurately obtained by determining the percentage of the cooling capacity already charged according to the latent heat value, the cooling capacity per unit time, the temperature difference value between the inlet and the outlet of the cooling pipe at the current moment, the cooling starting moment and the current moment, and the intelligent management of the cooling capacity is further realized.
