[0002] In a chiller device, when the external load heats up, in order to keep the supply liquid temperature stable, an electronic expansion valve and an electric heater are used to control the water tank temperature in the high temperature section.

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here.

[0045] Figure 1 It is a flowchart of a water tank temperature control method provided by an embodiment of the present invention. This embodiment is applicable to a chiller device. When the external load heats up, to ensure the stability of the supply liquid temperature, in the high-temperature section, the electronic expansion valve and the electric heater are used to control the water tank temperature. This method can be executed by a water tank temperature control device, and the control device can be implemented in the form of hardware and / or software. The control device can be configured in any electronic device with communication functions. See Figure 1, the method comprising:

[0046] S110, obtaining water tank characteristic data and load characteristic data; the water tank characteristic data includes the real-time temperature of the water tank, and the load characteristic data includes the real-time temperature of the load.

[0047] Specifically, the real-time temperature of the water tank and the real-time temperature of the load are measured by temperature sensors.

[0048] S120. Calculate the current value of the water tank temperature, the rate of change of the water tank temperature, the current value of the load temperature, and the rate of change of the load temperature respectively according to the real-time temperature of the water tank and the real-time temperature of the load.

[0049] Specifically, record the water tank at different times t 1 , t 2 , ..., t n Real-time temperature T w1 , T w2 ,…,T wn And the load at the same corresponding time t 1 , t 2 ,…,t n Real-time temperature T l1 , T l2 ,…,T ln , taking the calculation of the temperature change rate of the water tank as an example, in the time interval Δt = t i+1 -t i The average rate of change of the water tank temperature is v wi for In some other embodiments, the instantaneous rate of change at a certain moment can also be estimated by curve fitting or numerical differentiation of the temperature data. For example, the central difference method in numerical differentiation is used to estimate the instantaneous rate of change at a certain moment. i The instantaneous rate of change of the water tank temperature v wi for Similarly, the calculation process of the load temperature change rate is the same as that of the water tank temperature change rate, which will not be repeated here. The current value of the water tank temperature and the current value of the load temperature are calculated by removing the maximum and minimum abnormal data and using the average value filtering algorithm. Among them, the temperature change rate refers to the change in temperature per unit time. The purpose of calculating the water tank temperature change rate and the load temperature change rate is to meet the customer's temperature control needs of linear cooling or linear heating.

[0050] S130. When the water tank temperature change rate and the load temperature change rate respectively meet the preset change rate thresholds, the first energy, the second energy and the third energy are calculated according to the water tank characteristic data and the load characteristic data, and the compensation energy required for the water tank electric heater is calculated according to the first energy, the second energy and the third energy.

[0051] Specifically, the rate of change of the water tank temperature and the rate of change of the load temperature respectively meet the preset rate-of-change thresholds. This means that there are pre-set specific values. When the rate of change of the water tank temperature reaches or exceeds this specific rate-of-change value set for the water tank, and the rate of change of the load temperature reaches or exceeds the specific rate-of-change value set for the load, the prerequisite conditions for subsequent operations such as energy calculation are met. In some other embodiments, the customer will set a preset temperature change rate for the load temperature according to their own control requirements. The rate of change of the water tank temperature will take the preset temperature change rate set for the load temperature as a reference, thereby controlling the water tank temperature so that the rate of change of the water tank temperature also meets the preset rate-of-change threshold. The water tank characteristic data usually includes the volume of the water tank, the specific heat capacity of the liquid in the water tank, the heat dissipation coefficient of the water tank, the real-time temperature of the water tank, etc. These data can describe the physical and thermal characteristics of the water tank. The load characteristic data generally includes the power of the load, the heat capacity of the load, the heat exchange coefficient between the load and the surrounding environment, etc., and is used to characterize the relevant characteristics of the load. The first energy can be the energy related to the change in the water tank temperature. For example, the energy calculated according to the specific heat capacity, mass and temperature change of the water tank, that is, Q = mcΔT, where Q is the energy, m is the mass of the liquid in the water tank, c is the specific heat capacity, and ΔT is the temperature change. The second energy can be the energy related to the change in the load temperature. Similar to the calculation method of the water tank energy, it is determined according to the heat capacity and other data of the load and its temperature change. For example, if the load is a heating element, the energy change corresponding to its temperature change can be calculated according to its own thermal parameters and temperature change. The third energy can be the energy related to other factors of the entire chiller system, such as the heat dissipated by the system to the surrounding environment, which can be calculated according to factors such as the heat exchange coefficients between the water tank and the load and the environment, the temperature difference, and time. This part of the energy takes into account the thermal interaction between the system and the external environment. In the chiller system, the water tank electric heater needs to provide a certain amount of energy to maintain the temperature and other states of the system stable or meet specific requirements. According to the first energy, second energy and third energy calculated above, the compensation energy required by the water tank electric heater is calculated through a certain mathematical relationship. For example, it can be that the sum of the first energy and the second energy plus a part of the third energy (considering the energy loss of the system, etc.) is the compensation energy that the water tank electric heater needs to provide to ensure that the water tank temperature and the load temperature can operate normally when meeting the preset rate-of-change threshold. The compensation energy calculation formula may be E 补偿 = E 1 + E 2 + kE 3 , where E 补偿 is the compensation energy, E 1 , E 2 , E 3 are the first, second and third energies respectively, and k is a coefficient related to the system characteristics.

[0052] In a chiller system, it is necessary to keep the water tank and the load within a specific temperature range to ensure the normal operation of all components of the system. By calculating the compensation energy required by the electric heater and providing the corresponding heat by the electric heater, the energy loss caused by heat dissipation, heat exchange, etc. can be compensated, so that the water tank temperature can be stabilized near the set value, thereby ensuring the stable operation of the entire system. The stable temperature helps to reduce the damage of equipment caused by factors such as thermal stress and thermal fatigue, extend the service life of the equipment, reduce the incidence of equipment failures, improve the reliability and stability of the system, reduce the maintenance cost and downtime. Calculating the compensation energy required by the electric heater can accurately control the output power and working time of the electric heater according to the actual energy demand of the system, avoiding excessive or insufficient energy supply. Compared with the traditional control method, it can effectively avoid energy waste and reduce the energy consumption cost.

[0053] The technical solution provided by the embodiment of the present invention includes obtaining water tank characteristic data and load characteristic data; calculating the current value of the water tank temperature, the change rate of the water tank temperature, the current value of the load temperature, and the change rate of the load temperature according to the real-time temperature of the water tank and the real-time temperature of the load; when the change rate of the water tank temperature and the change rate of the load temperature respectively meet the preset change rate thresholds, calculating the first energy, the second energy, and the third energy according to the water tank characteristic data and the load characteristic data, and calculating the compensation energy required by the water tank electric heater according to the first energy, the second energy, and the third energy. It can quickly meet the customer's requirements for the stability of the liquid supply temperature and the fast response time, improve the control ability of the equipment, and at the same time reduce the energy consumption of the system; in the high temperature section, the compressor system can be stopped, which plays a great role in improving the overall performance of the equipment, reducing the cost of the equipment, and extending the life of the equipment.

[0054] On the basis of the above embodiment, optionally, the water tank characteristic data further includes the specific heat capacity of the water tank coolant, the mass of the water tank coolant, and the temperature change amount of the water tank coolant, and the load characteristic data further includes the specific heat capacity of the load, the mass of the load, and the temperature change amount of the load.

When the change rate of the water tank temperature and the change rate of the load temperature respectively meet the preset change rate thresholds, calculate the first energy according to the specific heat capacity of the water tank coolant, the mass of the water tank coolant, and the temperature change amount of the water tank coolant. The first energy is the energy required for the water tank coolant to reach the preset temperature threshold from the current value of the water tank temperature.

[0056] Specifically, when the change rate of the water tank temperature and the change rate of the load temperature respectively meet the preset change rate thresholds, calculate the first energy according to the product of the specific heat capacity of the water tank coolant, the mass of the water tank coolant, and the temperature change amount of the water tank coolant.

[0057] Exemplarily, the first energy is calculated using the following formula:

[0058] Q1 = m × c × ΔT; where Q1 is the first energy, m is the mass of the coolant in the water tank, c is the specific heat capacity of the coolant in the water tank, and ΔT is the temperature change of the coolant in the water tank.

[0059] S132. When the temperature change rate of the water tank and the temperature change rate of the load respectively meet the preset change rate thresholds, calculate the second energy according to the specific heat capacity of the load, the negative mass, and the temperature change of the load. The second energy is the energy required for the load to reach the preset temperature threshold from the current value of the load temperature.

[0060] Specifically, when the temperature change rate of the water tank and the temperature change rate of the load respectively meet the preset change rate thresholds, calculate the second energy according to the product of the specific heat capacity of the load, the negative mass, and the temperature change of the load.

[0061] Exemplarily, the second energy is calculated using the following formula:

[0062] Q2 = m × c × ΔT; where Q2 is the second energy, m is the mass of the load, c is the specific heat capacity of the load, and ΔT is the temperature change of the load.

[0063] S133. Calculate the third energy according to the preset calibration table. The third energy is the loss energy of the system.

[0064] Among them, the preset calibration table is a data table containing the energy correlation between the water tank and the load.

[0065] Specifically, through big data analysis, using the test data recorded by the system in the past, simulate and calculate the energy that the system needs to supplement, that is, the loss energy of the system.

[0066] S134. Calculate the compensation energy required for the water tank electric heater according to the first energy, the second energy, and the third energy.

[0067] Specifically, calculate the compensation energy required for the water tank electric heater according to the sum of the first energy, the second energy, and the third energy.

[0069] Convert the compensation energy required for the electric heater into a percentage output signal; convert the percentage output signal into a pulse modulation signal; adjust the output power of the water tank electric heater according to the pulse modulation signal.

[0070] Among them, the output power of the water tank electric heater is calculated by the quotient of the compensation energy required for the electric heater and time.

[0071] Specifically, convert the compensation energy required by the electric heater into a percentage output signal; convert the percentage output signal into a pulse modulation signal; control the solid-state relay according to the pulse modulation signal, thereby adjusting the output power of the electric water heater in the water tank.
