Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment control technology, and in particular to a water tank temperature control method, device, electronic equipment, storage medium, and program product. Background Technology

[0002] In chiller equipment, when the external load heats up, the supply liquid temperature needs to be stable. Therefore, the high-temperature section uses an electronic expansion valve and an electric heater to control the water tank temperature. However, this control method has a problem: the electronic expansion valve is fixed at the minimum valve step (constant cooling capacity). When the external load heats up, the temperature overshoot often becomes too large, or during the linear temperature rise control process, the temperature rise rate often becomes too large or the temperature rise rate is insufficient.

[0003] Traditional control methods employ PID (Proportional-Integral-Derivative) control. However, this method can lead to excessive or insufficient output from the electric heater when the load changes, resulting in significant temperature fluctuations and an inability to quickly meet customer demands.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

This embodiment is applicable to chiller equipment where, when the external load heats up, an electronic expansion valve and an electric heater are used to control the water tank temperature in the high-temperature section to ensure a stable supply liquid temperature. This method can be executed by a water tank temperature control device, which can be implemented in hardware and / or software. This control device can be configured in any electronic device with communication capabilities. See also... Figure 1The method includes:

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

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

[0048] S120. Based on the real-time temperature of the water tank and the real-time temperature of the load, 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.

[0049] Specifically, the water tank was recorded at different times. Real-time temperature and the load at the same corresponding time Real-time temperature Taking the calculation of the rate of change of water tank temperature as an example, at a time interval The average rate of change of water temperature inside the tank for In other embodiments, the instantaneous rate of change at a given moment can also be estimated by curve fitting or numerical differentiation of the temperature data. For example, the central difference method in numerical differentiation can be used to estimate the instantaneous rate of change at time [time value missing]. instantaneous rate of change of water tank temperature for Similarly, the calculation process for the load temperature change rate is the same as that for the water tank temperature change rate, and will not be repeated here. Both the current water tank temperature and the current load temperature are calculated using an average value filtering algorithm after removing the largest and smallest outlier data. The temperature change rate refers to the amount of temperature change 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 requirements for linear cooling or linear heating.

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

[0051] Specifically, the rate of change of water tank temperature and the rate of change of load temperature each meet a preset rate of change threshold. This means that there are pre-set specific values. When the rate of change of water tank temperature reaches or exceeds this specific rate of change value set for the water tank, and the rate of change of load temperature reaches or exceeds the specific rate of change value set for the load, the prerequisites for subsequent energy calculations and other operations are met. In some other embodiments, the customer sets a preset rate of change of load temperature according to their own control requirements. The rate of change of water tank temperature is then referenced to the preset rate of change of load temperature to control the water tank temperature, ensuring that the rate of change of water tank temperature also meets the preset rate of change threshold. Water tank characteristic data typically includes the water tank volume, the specific heat capacity of the liquid in the water tank, the heat dissipation coefficient of the water tank, and the real-time temperature of the water tank. These data describe the physical and thermal characteristics of the water tank. Load characteristic data generally includes the load power, the load heat capacity, and the heat exchange coefficient between the load and the surrounding environment, used to characterize the relevant characteristics of the load. The first energy can be the energy related to the change of water tank temperature. For example, the energy calculated based on the specific heat capacity, mass, and temperature change of the water tank, i.e. Where Q is energy, m is the mass of liquid in the tank, and c is the specific heat capacity. The first energy is the temperature change. The second energy can be the energy related to the load temperature change. Similar to the calculation method of the water tank energy, it is determined based on the load's heat capacity and its temperature change. For example, if the load is a heating element, the energy change corresponding to its temperature change can be calculated based on 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 lost by the system to the surrounding environment. This can be calculated based on the heat exchange coefficient 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 system's temperature and other states stably or to meet specific requirements. Based on the first, second, and third energies calculated above, the compensation energy required by the water tank electric heater is calculated through a certain mathematical relationship. For example, the sum of the first and second energies plus a portion of the third energy (considering the system's energy loss, etc.) is the compensation energy that the water tank electric heater needs to provide to ensure that the system can operate normally when the water tank temperature and load temperature meet the preset rate of change threshold. The compensation energy calculation formula may be: ,in, It is to compensate for energy. , These represent the first, second, and third energies, respectively, and k is a coefficient related to the system characteristics.

[0052] In chiller systems, maintaining the water tank and load within a specific temperature range is crucial for the proper functioning of all components. By calculating the required compensation energy for the electric heater and supplying the corresponding heat, energy losses due to heat dissipation and heat exchange can be compensated, stabilizing the water tank temperature near the set value and ensuring stable system operation. Stable temperature helps reduce damage to equipment caused by thermal stress and fatigue, extending equipment lifespan, lowering failure rates, improving system reliability and stability, and reducing maintenance costs and downtime. Calculating the required compensation energy for the electric heater allows for precise control of its output power and operating time based on the system's actual energy demands, preventing over- or under-supply of energy. Compared to traditional control methods, this effectively avoids energy waste and reduces energy consumption costs.

[0053] The technical solution provided by this invention acquires water tank characteristic data and load characteristic data; based on the real-time water tank temperature and the real-time load temperature, it calculates 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; when the rate of change of the water tank temperature and the rate of change of the load temperature respectively meet preset rate of change thresholds, it calculates a first energy, a second energy, and a third energy based on the water tank characteristic data and the load characteristic data, and calculates the compensation energy required for the water tank electric heater based on the first energy, the second energy, and the third energy. This allows for rapid adaptation to customer demands for stable liquid supply temperature and fast response time, improving equipment control capabilities while reducing system energy consumption; it also allows the compressor system to be stopped at high temperatures, significantly improving overall equipment performance, reducing equipment costs, and extending equipment lifespan.

[0054] Based on the above embodiments, optionally, the water tank characteristic data also includes the specific heat capacity of the water tank refrigerant, the mass of the water tank refrigerant, and the temperature change of the water tank refrigerant; the load characteristic data also includes the specific heat capacity of the load, the mass of the load, and the temperature change of the load. S130 specifically includes:

[0055] S131. When the rate of change of water tank temperature and the rate of change of load temperature meet the preset rate of change threshold respectively, calculate the first energy based on the specific heat capacity of water tank refrigerant, the mass of water tank refrigerant, and the amount of temperature change of water tank refrigerant. The first energy is the energy required for the water tank refrigerant to go from the current water tank temperature to the preset temperature threshold.

[0056] Specifically, when the rate of change of water tank temperature and the rate of change of load temperature meet the preset rate of change thresholds, the first energy is calculated based on the product of the specific heat capacity of the water tank refrigerant, the mass of the water tank refrigerant, and the amount of temperature change of the water tank refrigerant.

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

[0058] In the formula, Q1 is the first energy, m is the mass of the coolant in the water tank, and c is the specific heat capacity of the coolant in the water tank. This represents the temperature change of the refrigerant in the water tank.

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

[0060] Specifically, when the rate of change of water tank temperature and the rate of change of load temperature meet the preset rate of change thresholds, the second energy is calculated based on the product of load specific heat capacity, load mass, and load temperature change.

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

[0062] In the formula, Q2 represents the second energy, m represents the load mass, and c represents the load specific heat capacity. This represents the change in load temperature.

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

[0064] The preset calibration table is a data table that includes the energy correlation between the water tank and the load.

[0065] Specifically, through big data analysis, the system uses previously recorded test data to simulate and calculate the energy required to replenish the system, which is also the energy loss of the system.

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

[0067] Specifically, the compensation energy required for the water tank electric heater is calculated based on the sum of the first energy, the second energy, and the third energy.

[0068] Optionally, based on the above embodiments, after S130, the following step is also included:

[0069] The required compensation energy for the electric heater is converted into a percentage output signal; the percentage output signal is converted into a pulse modulation signal; and the output power of the water tank electric heater is adjusted according to the pulse modulation signal.

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

[0071] Specifically, the compensation energy required by the electric heater is converted into a percentage output signal; the percentage output signal is converted into a pulse modulation signal; and the solid-state relay is controlled according to the pulse modulation signal to adjust the output power of the water tank electric heater.
