[0064] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0065] Unless specifically stated otherwise, the relative arrangement of components and steps, the numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure.

[0066] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0067] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0068] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0069] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0070] The inventor found through research that in the clean workshop of the related technology, due to the needs of process production, it is necessary to strictly control the strict humidity requirements in the clean room. However, in the transition season, the outdoor fresh air dehumidification volume is very small, resulting in low-frequency operation of the low-temperature chiller, low-efficiency operation, and frequent start-stop and other faults. It is impossible to maintain the water temperature fluctuation range within the constant ±1°C requirement range, and the humidity control effect is poor. For such situations, the related technology has not yet had a relatively mature solution. Conventional air conditioners cannot meet the requirements of low temperature and good uniformity. Such rooms often have their own uniqueness, such as high temperature precision control, which requires comprehensive consideration of the distribution of airflow in the room and the layout of indoor shelves. It is more challenging to achieve the ideal environment required by the end by combining the requirements of various aspects.

[0071] Related Technology Conventional air conditioning systems can achieve cleanliness, but for medium and low temperature areas, conventional chilled water cannot handle the required temperature, and the indoor air supply system will condense due to low temperature. Once condensation occurs, cleanliness cannot be achieved. Due to the characteristics of cold air itself, the precision control of temperature and humidity needs to be achieved, and the stability of the low-temperature chiller needs to be improved to achieve the high energy efficiency ratio requirements of the entire air conditioning system.

[0072] The related technology still has the following technical problems:

[0073] 1. Related technologies: The load of the air-conditioning room is in the low efficiency range of the system, which leads to the low energy efficiency of the low-temperature chiller. In addition, when the room is running stably, there is still room for improvement in the overall system energy efficiency, which has not been regulated.

[0074] 2. Related technologies When the main engine is under load, it is prone to frequent start-stop and other faults, unable to meet the water temperature fluctuation requirement of ±1℃, and has poor humidity control effect.

[0075] In view of at least one of the above technical problems, the present disclosure provides an energy adaptation method and device, an air conditioning system, a storage medium and a program product. The present disclosure is described below through specific embodiments.

The different chilled water is led to the end of each area respectively, and the different cooling water is led to the same cooling tower system (cooling tower 60) for heat dissipation.

[0097] Related technology: The two types of chilled water in the low-temperature system and the medium-temperature system do not interfere with each other. Each system has its own corresponding actual load situation and adjusts its own energy efficiency. However, in actual projects, it is found that when each adjustment achieves relatively efficient operation, the efficiency of the overall system still has room for improvement.

[0098] The above-mentioned embodiment of the present disclosure connects the low-temperature system and the medium-temperature system in parallel through a plate heat exchanger for indirect heat exchange, and can perform overall intelligent regulation to maximize the energy efficiency of the integrated system.

[0101] The energy adaptation device and method disclosed herein are further described below through specific embodiments.

[0102] Figure 3 Schematic diagram of some embodiments of the energy adaptation method disclosed in the present invention. Figure 3 The embodiment can be performed by the air conditioning system of the present disclosure or the energy adapter device of the present disclosure. Figure 3 As shown, Figure 3 The method of the embodiment may include at least one of steps 100 to 300 .

[0103] Step 100, obtaining the actual low-temperature refrigeration capacity of the low-temperature system of the air-conditioning system.

[0104] Step 200, obtaining the actual medium-temperature cooling capacity of the medium-temperature system of the air-conditioning system.

[0105] Step 300, using a medium and low temperature panel exchange system to adjust the load of the low temperature system and the medium temperature system.

[0106] In some embodiments of the present disclosure, the load is cooling capacity, in kW.

[0107] In some embodiments of the present disclosure, the load adjustment may be load distribution.

[0108] The above-mentioned embodiment of the present disclosure connects the low-temperature system and the medium-temperature system in parallel through a plate heat exchanger for indirect heat exchange, and can perform overall intelligent regulation to maximize the energy efficiency of the integrated system.

[0109] The above-mentioned embodiments of the present disclosure can efficiently distribute the load to the low-temperature system and the medium-temperature system according to the load conditions, and regulate the entire air-conditioning system including the low-temperature system and the medium-temperature system, so that the entire air-conditioning system can operate at the highest efficiency, thereby reducing the overall operating energy consumption.

[0110] In some embodiments of the present disclosure, step 300 may include at least one of steps 310 to 320 .

[0111] Step 310, calculating the maximum power of the system according to the actual low-temperature cooling capacity, the actual medium-temperature cooling capacity and the energy efficiency characteristic curve function.

[0112] In some embodiments of the present disclosure, both the low-temperature chiller and the medium-temperature chiller are air-conditioning units. There are two types of air-conditioning units: screw units and centrifugal units. There is an energy efficiency characteristic curve for different models. The curve is a function composed of an energy efficiency COP parameter (f), a load rate parameter (x), and a cooling water temperature parameter L: f (x, L). Because the low-temperature chiller and the medium-temperature chiller in the system of the present disclosure are connected to the same cooling water system (cooling tower system), the cooling water temperature L is the same, and the energy efficiency characteristic curve is simplified to: f (x).

[0113] In some embodiments of the present disclosure, COP (Coefficient Of Performance) refers to the cooling capacity that can be obtained per unit power consumption.

[0114] In some embodiments of the present disclosure, step 310 may include at least one of steps 311 to 313 .

[0115] Step 311, determining the actual low-temperature load rate x1 according to the actual low-temperature cooling capacity q1 and the rated low-temperature cooling capacity Q1.

[0116] In some embodiments of the present disclosure, the actual low-temperature load rate x1 is determined by a low-temperature heat meter, and the low-temperature heat meter and the medium-temperature heat meter monitor the low-temperature cooling capacity q1 and the medium-temperature cooling capacity q2, respectively.

[0117] In some embodiments of the present disclosure, step 311 may include: determining the actual low temperature load rate x1 according to formula (1).

[0118] x1=q1 / Q1 (1)

[0119] Step 312, determining the actual medium-temperature load rate x2 according to the actual medium-temperature cooling capacity q1 and the rated medium-temperature cooling capacity Q2.

[0120] In some embodiments of the present disclosure, step 312 may include: determining the actual medium temperature load rate x2 according to formula (2).

[0121] x2=q2 / Q2 (2)

[0122] Step 313, calculating the maximum power of the system according to the actual low-temperature load rate, the actual medium-temperature load rate, the actual low-temperature cooling capacity, the actual medium-temperature cooling capacity and the energy efficiency characteristic curve function.

[0123] The above embodiment of the present disclosure specifically calculates the low temperature load rate and the medium temperature load rate, and simulates the energy efficiency characteristic curve function to accurately calculate the theoretical maximum power of the system, so that the actual power of the system reaches the theoretical maximum power of the system, and load adjustment is achieved. Therefore, the above embodiment of the present disclosure can meet the requirements of the entire air-conditioning system to efficiently adapt according to the actual load conditions of low temperature and medium temperature during operation.

[0124] In some embodiments of the present disclosure, step 313 may include at least one of steps a to e.

[0125] Step a, setting a load increase value a and a load rate increase value A corresponding to the load increase value.

[0126] In some embodiments of the present disclosure, the load rate and the load are two linearly positively correlated quantities. a is the value of increasing the load, and the load rate will also increase accordingly. A is the increased load rate, and a is the increased load.

[0127] In some embodiments of the present disclosure, the load increase value a may be 10 or 20.

[0128] In some embodiments of the present disclosure, the actual set value of the load increase value a is determined by on-site commissioning.

[0129] Step b, determining the target total power P0 according to the load increase value a, the load rate increase value A, the actual low-temperature load rate x1, the actual medium-temperature load rate x2, the actual low-temperature cooling capacity q1, the actual medium-temperature cooling capacity q2 and the energy efficiency characteristic curve function f(x).

[0130] In some embodiments of the present disclosure, step b may include at least one of steps b1 to b5.

[0131] Step b1, determining the low-temperature energy efficiency parameter f(x1+A) according to the actual low-temperature load rate x1, the load rate increase value A and the energy efficiency characteristic curve function f(x).

[0132] Step b2, determining the low-temperature system power P1 = q1+a / f(x1+A) according to the low-temperature energy efficiency parameter f(x1+A), the load increase value a and the actual low-temperature cooling capacity q1.

[0133] Step b3, determining the medium-temperature energy efficiency parameter f(x2-A) according to the actual medium-temperature load rate x2, the load rate increase value A and the energy efficiency characteristic curve function f(x).

[0134] In some embodiments of the present disclosure, since a is the load transferred from low temperature to medium temperature, the low temperature load rate x1 increases by A while the medium temperature load rate x2 decreases by A.

[0135] Step b4, determine the medium temperature system power P2 = q2 + a / f (x2-A) according to the medium temperature energy efficiency parameter f (x2-A), the load increase value a and the actual medium temperature cooling capacity q2.

[0136] Step b5, determining the target total power P0 according to the low temperature system power P1 and the medium temperature system power P2.

[0137] The above-mentioned embodiments of the present disclosure can accurately determine the power of the low-temperature system and the power of the medium-temperature system by simulating the energy efficiency characteristic curves respectively, and then accurately determine the target total power. Therefore, the above-mentioned embodiments of the present disclosure can efficiently distribute the load by using independent plate exchange systems for the low-temperature system and the medium-temperature system, monitor the cold load of the low-temperature system through a heat meter, analyze the load under intelligent and efficient control, and calculate by simulating the energy efficiency curve of the low-temperature system, so as to improve the comprehensive system energy efficiency and achieve the effect of energy saving and carbon reduction under the premise of ensuring stable operation.

[0138] In some embodiments of the present disclosure, step b5 may include: determining the target total power P0 according to formula (2).

[0139] P0=[q1+a / f(x1+A)]+[q2+a / f(x2-A)] (2)

[0140] Step c, determining whether the target total power P0 is greater than the actual operating total power.

[0141] Step d, when the target total power P0 is greater than the actual operating total power, determine whether the target total power P0 has reached a historical maximum. If the target total power has reached a historical maximum, determine the maximum value of the target total power and execute step e; otherwise, if the target total power has not reached a historical maximum, increase the load increase value a and the load rate increase value A corresponding to the load increase value, and then repeat steps b to d.

[0142] The above embodiment of the present disclosure can simulate the energy efficiency characteristic curve function by iteratively increasing the load increase value and the load rate increase value corresponding to the load increase value, and finally accurately determine the maximum value of the target total power. Therefore, the above embodiment of the present disclosure can efficiently distribute the load by using an independent plate exchange system for the low temperature system and the medium temperature system, monitor the cold load of the low temperature system through a heat meter, and analyze the load under intelligent and efficient control.

[0143] In some embodiments of the present disclosure, when the target total power P0 is not greater than the actual operating total power, the new a value is tested cyclically until P0>actual P, and the system will be regulated according to this a; if P0<actual P is calculated too many times, the system will stop and maintain stable operation.

[0144] Step e: taking the highest value of the target total power as the system maximum power Pmax.

[0145] The above-mentioned embodiments of the present disclosure can simulate the energy efficiency characteristic curve function and take the maximum value of the target total power as the maximum power of the system. Therefore, the present disclosure can improve the comprehensive system energy efficiency while ensuring stable operation by simulating the energy efficiency curve of the low-temperature system for calculation.

[0146] Step 320, by monitoring the actual low-temperature cooling capacity and the actual medium-temperature cooling capacity, the frequency of the low-temperature panel water exchange pump and the medium-temperature panel water exchange pump is controlled so that the actual system power reaches the system maximum power Pmax, thereby achieving load adjustment.

[0147] The above-mentioned embodiments of the present disclosure can efficiently distribute the load by adopting independent plate exchange systems for the low-temperature system and the medium-temperature system, monitor the cooling load of the low-temperature system by means of a heat meter, analyze the load under intelligent and efficient control, and calculate by simulating the energy efficiency curve of the low-temperature system. Under the premise of ensuring stable operation, the overall system energy efficiency is improved to achieve the effect of energy saving and carbon reduction.

[0148] In some embodiments of the present disclosure, step 300 may include: after the system is stable, start the high-efficiency adaptation mode, the energy adaptation device simulates the calculation, monitors the actual low-temperature heat meter q1, calculates the low temperature x1, monitors the actual medium-temperature heat meter q2, calculates the medium temperature x2, adds a to the low temperature x1, calculates the low temperature f(x1+A), calculates the medium temperature f(x2-A), calculates P0=[q1+a / f(x1+a)]+[q2+a / f(x2-a)], compares P0 with the actual operating total power, if P0 is greater than the actual power, the intelligent system increases the a value and continues to iterate the calculation until P0 is the highest in history, turns on the plate replacement water pump and valve, controls the water pump frequency by monitoring the heat meter, makes the entire system reach the P0 state, and completes the high-efficiency adaptation.

[0149] In some embodiments of the present disclosure, if the actual low-temperature cooling capacity monitored by the low-temperature heat meter is less than the calculated value, the frequency of changing the water pump of the cryopanel is reduced.

[0150] In some embodiments of the present disclosure, if the frequency of replacing the plate and the water pump is increased, the actual total operating power becomes smaller. Specifically, the actual total operating power is jointly determined by the host (low-temperature chiller and medium-temperature chiller), water pump, and cooling tower. Although the water pump system power is increased, the host reaches the high-efficiency operation range, and the power reduced by the host is greater than the power increased by the water pump. Therefore, the total power becomes smaller, which is more energy-saving.

[0153] Step 42: When the actual low-temperature load rate x1 is lower than the predetermined load rate, it is determined that the air conditioning system is operating at a low frequency.

[0156] Step 43: When the air conditioning system is running at a low frequency, it is determined whether the actual low-temperature cooling capacity q1 of the low-temperature system is less than the safety load value M.

[0157] Step 44, when the actual low-temperature cooling capacity q1 of the low-temperature system is less than the safety load value M, the low-temperature panel water exchange pump and valve, the medium-temperature water exchange pump and valve are turned on, and by monitoring the actual low-temperature cooling capacity and the actual medium-temperature cooling capacity, the frequency of the low-temperature panel water exchange pump and the medium-temperature panel water exchange pump is controlled to make the actual low-temperature cooling capacity q1 equal to the safety load value M, thereby reaching a safe state.

[0168] Step 455, adjusting the cooling water pump frequency according to the inlet and outlet water pressure difference of the cooling system, wherein the cooling water pump includes a low-temperature cooling water pump and a medium-temperature cooling water pump.

[0169] In some embodiments of the present disclosure, step 455 may include: the cooling water pump adjusts the frequency according to the pressure difference. When the pressure difference of the cooling system is high, the cooling water pump frequency needs to be reduced, and when the pressure difference is low, the cooling water pump frequency needs to be increased.

[0170] Step 456, adjusting the frequency of the low-temperature refrigeration water pump according to the temperature difference between the inlet and outlet water of the low-temperature refrigerator.

[0171] In some embodiments of the present disclosure, step 456 may include: the low temperature refrigeration pump adjusts the frequency according to the inlet and outlet water temperature difference of the low temperature refrigerator. When the temperature difference is high, the refrigeration pump frequency needs to be increased for adjustment, and when the temperature difference is low, the refrigeration frequency needs to be reduced.

[0173] In some embodiments of the present disclosure, step 457 may include: the medium temperature refrigeration pump adjusts the frequency according to the inlet and outlet water temperature difference of the medium temperature refrigerator. When the temperature difference is high, the refrigeration pump frequency needs to be increased for adjustment, and when the temperature difference is low, the refrigeration frequency needs to be reduced.

[0175] Step 46, when the low temperature system and the medium temperature system reach the set water temperature requirements, it is determined that the entire system (the entire air conditioning system) is in a stable state.

[0176] Step 47, when the air conditioning system is in a stable state, the low temperature system and the medium temperature system are load adjusted by using the medium and low temperature panel exchange system, that is, executing Figure 3 Step 300 of an embodiment.

[0177] In some embodiments of the present disclosure, the stable state means that the load, water temperature, and pressure of the entire air-conditioning system do not change significantly, are controlled within a fine adjustment of 3%, and the values ​​are relatively stable.

[0178] The above embodiment of the present disclosure can accurately determine whether to enter the normal mode through the low temperature load rate. In the normal mode, the low temperature system and the medium temperature system of the air conditioning system are controlled to reach the set water temperature requirement, and then the load adjustment plan is executed. Therefore, the above embodiment of the present disclosure can achieve the stable operation range of the low temperature system by distributing the load and ensure the water supply temperature.
