Description

Technical Field

[0001] This invention relates to the field of air conditioning control technology, and in particular to a method, system, equipment and medium for energy-saving group control of air conditioning and water systems. Background Technology

[0002] Water-based central air conditioning systems consist of both air and water systems, which work together to serve a building. Water-based central air conditioning systems use water as the heating and cooling medium. The main unit (chilled water unit) cools the water, which is then transported through water pipes to the fan coil units at each terminal, where it exchanges heat with the indoor air.

[0003] In most projects, the control of the air conditioning system and the water system are separate and independent, forming "information silos" where the air conditioning system and the water system operate independently. However, the air conditioning system and the water system are highly coupled. This independent control method for the air conditioning system and the water system causes a mismatch between supply and demand on the air side and the water side, which affects the comfort of the building (indoor temperature does not meet the standard) and also causes energy waste. Summary of the Invention

[0004] The purpose of this invention is to provide a method, system, device, and medium for wind and water-linked energy-saving group control, in order to solve the problems existing in the prior art. To achieve the above objective, this invention provides the following technical solution:

[0005] In a first aspect, the present invention provides a wind and water linkage energy-saving group control method, comprising the following steps:

[0006] S11. Read the total number of online thermostats, the number of fan coil units turned on, the actual room temperature, the set room temperature, and the thermostat operating mode.

[0007] S12. Calculate the room temperature compliance rate = number of thermostats whose actual room temperature is within the range of [lower limit of set temperature deviation, upper limit of set temperature deviation] / total number of thermostats online;

[0008] S13. If the room temperature compliance rate is higher than the set value, and the room thermostats that meet the standard are in low wind mode or no wind mode if they are higher than the set percentage P%, then the main unit's outlet water temperature setting will be increased; if the room temperature compliance rate is higher than the set value, but the room thermostats that meet the standard are in low wind mode or no wind mode if they are not higher than the set percentage P%, then the main unit will maintain the original setting.

[0009] If the room temperature compliance rate is not higher than the set value, determine whether the number of thermostats whose actual room temperature exceeds the upper limit of the set temperature deviation is greater than the number of thermostats whose actual room temperature is lower than the lower limit of the set temperature deviation. If it is greater, the room temperature is in a positive deviation, and the air volume of all non-compliant rooms cannot be further increased. At this time, the set temperature of the main unit's water outlet is reduced.

[0010] S14. Repeat S11~S13 according to the set cycle period T1.

[0011] As a further technical solution, in step S13, if the room temperature compliance rate is not higher than the set value and the room temperature has a positive deviation, but there is room for further adjustment of the air volume in the non-compliant rooms, the main unit will maintain the original setting operation; if the room temperature compliance rate is not higher than the set value, but the room temperature has a negative deviation, and the temperature controllers of compliant rooms that are not higher than the set percentage P% are in low wind mode or no wind mode, the main unit will maintain the original setting operation.

[0012] As a further technical solution, the following steps are also included:

[0013] S21. Read the total number of online thermostats, the number of fan coil units in operation, the actual room temperature, the set room temperature, the total number of main units, and the number of main units in operation;

[0014] S22. Calculate the fan coil unit operating rate, the main unit operating rate, and the room temperature compliance rate;

[0015] S23. If the fan coil unit operating rate is greater than the main unit operating rate, and the room temperature compliance rate is less than the set value, and the number of main units in operation is less than the total number of main units, then add one unit; if the fan operating rate is not greater than the main unit operating rate, and the room temperature compliance rate is not less than the set value, then shut down one unit.

[0016] S24. Repeat S21~S23 according to the set cycle period T2, and run synchronously with step S14.

[0017] As a further technical solution, in step S23, if the fan coil unit operating rate is greater than the main unit operating rate, but the room temperature compliance rate is not less than the set value, the original number of units will continue to operate; if the fan coil unit operating rate is greater than the main unit operating rate, and the room temperature compliance rate is less than the set value, but the number of main units in operation is not less than the total number of main units, the original number of units will continue to operate.

[0018] As a further technical solution, in step S23, if the fan start-up rate is not greater than the host start-up rate, but the room temperature compliance rate is less than the set value, the original number of units will continue to operate.

[0019] As a further technical solution, the following steps are also included:

[0020] S31. Read the thermostat's current power-on duration, actual room temperature, set room temperature, and thermostat's operating mode;

[0021] S32. If the current operating time of the thermostat is greater than the set time T5, and the actual room temperature is less than the set temperature, then the fan coil unit thermostat will be reset to the set temperature; if the current operating time of the thermostat is greater than the set time T5, and the actual room temperature is not less than the set temperature, then the fan coil unit thermostat will maintain its original setting; if the current operating time of the thermostat is not greater than the set time T5, then the fan coil unit thermostat will maintain its original setting.

[0022] S33. Repeat S31~S32 according to the set cycle period T3, and run synchronously with steps S14 and S24.

[0023] As a further technical solution, the following steps are also included:

[0024] S41. Read the total number of online thermostats, the number of fan coil units in operation, the actual room temperature, the set room temperature, and the current fan speed of the thermostat.

[0025] S42. Calculate the deviation between the actual temperature and the set temperature of each room. If the deviation of a room is greater than the positive deviation threshold, send a command to the thermostat of that room to increase the air volume. If the deviation of a room is not greater than the positive deviation threshold and is less than the negative deviation threshold, send a command to the thermostat of that room to decrease the air volume. If the deviation of a room is not greater than the positive deviation threshold and is not less than the negative deviation threshold, maintain the original setting.

[0026] S43. Repeat S41~S42 according to the set cycle period T4, and run synchronously with steps S14, S24 and S33.

[0027] Secondly, this invention provides a wind and water linkage energy-saving group control system, comprising:

[0028] The controlled equipment layer includes fan coil units and main units;

[0029] The control execution layer includes a host controller and a temperature controller. The host controller can communicate with the host and issue control commands, and the temperature controller can communicate with the fan coil unit and issue control commands.

[0030] The platform layer is equipped with a main controller that can execute the wind and water linkage energy-saving group control method as described in the first aspect.

[0031] Thirdly, the present invention provides an electronic device, the electronic device comprising:

[0032] At least one processor; and,

[0033] A memory communicatively connected to the at least one processor; wherein,

[0034] The memory stores a computer program that can be executed by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform the wind and water linkage energy-saving group control method as described in the first aspect.

[0035] Fourthly, the present invention provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the wind and water linkage energy-saving group control method as described in the first aspect.

[0036] The beneficial effects of the present invention are as follows:

[0037] (1) This invention combines the room temperature compliance rate, whether the room temperature deviates positively, and the air volume as judgment conditions to determine when the actual building's cooling load demand is small and the indoor cooling supply is excessive. It can then promptly increase the target outlet water temperature of the main unit to achieve energy saving. Simultaneously, combining the above judgment conditions, it can promptly lower the target outlet water temperature of the main unit when the actual building's cooling load demand increases and the indoor cooling supply is insufficient, thus ensuring indoor comfort. This invention, by comprehensively considering judgment conditions including air volume, can adjust the main unit's outlet water temperature to achieve air-water linkage while ensuring indoor comfort and energy-saving effects.

[0038] (2) The group control method of the present invention combines the start-up rate of the fan coil unit, the start-up rate of the main unit, the room temperature compliance rate, and the number of main units in operation to determine the load demand of the building, and then add or remove the main unit of the refrigeration unit to achieve energy saving in system operation.

[0039] (3) The present invention can realize the automatic reset of the set temperature of the fan coil unit. Under the condition of meeting the user's need for rapid cooling when entering the room, the set temperature of the fan coil unit thermostat is restored in time, avoiding the waste of energy caused by the set temperature being adjusted too low for a long time.

[0040] (4) This invention utilizes a group control method to actively adjust the airflow of fan coil units. By changing the airflow of the fan coil units, the cooling capacity of rooms with insufficient cooling capacity is increased, and the cooling capacity of rooms with excessive cooling capacity is reduced, thus promoting a balance between the cooling capacity and the cooling demand of the rooms. Since the air velocity of some fan coil units is actively reduced, the power consumption of these fan coil units is reduced; at the same time, the air velocity of the fan coil units in some rooms that do not meet the cooling standards is increased, that is, the cooling capacity of these fan coil units is increased, thereby improving the comfort of these rooms and achieving the dual purpose of energy saving and providing comfort.

[0046] The technical solutions in typical embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0047] Example 1

[0048] like Figure 1 As shown, this embodiment provides a wind and water linkage energy-saving group control method, including the following steps:

[0049] S11. Read the total number of online thermostats, the number of fan coil units turned on, the actual room temperature, the set room temperature, and the thermostat operating mode.

[0050] S12. Calculate the room temperature compliance rate = number of thermostats whose actual room temperature is within the range of [lower limit of set temperature deviation, upper limit of set temperature deviation] / total number of thermostats online; In this embodiment, the minimum set value for the room temperature compliance rate is 90% by default.

[0051] In this embodiment, the temperature deviation thresholds are set with a default negative threshold of -1.5℃ and a positive threshold of 1.5℃. These thresholds can be set independently for each thermostat or uniformly. The lower limit of the temperature deviation is set as the room set temperature plus the negative threshold, and the upper limit of the temperature deviation is set as the room set temperature plus the positive threshold.

[0052] S13、(1)If the room temperature compliance rate is higher than the set value, and the room temperature controllers that meet the standard are in low wind mode or no wind mode if they are higher than the set percentage P%, then the main unit's outlet water temperature setting will be increased;(2)If the room temperature compliance rate is higher than the set value, but the room temperature controllers that meet the standard are in low wind mode or no wind mode if they are not higher than the set percentage P%, then the main unit will maintain the original setting and the main unit's outlet water temperature will remain unchanged.

[0053] (1) If the room temperature compliance rate is not higher than the set value, determine whether the number of thermostats whose actual room temperature exceeds the upper limit of the set temperature deviation is greater than the number of thermostats whose actual room temperature is lower than the lower limit of the set temperature deviation. If it is greater, the room temperature is positive deviation, and the air volume of all non-compliant rooms cannot be further increased. At this time, the main unit's outlet water setting temperature is reduced. (2) If the room temperature compliance rate is not higher than the set value, and the room temperature is positive deviation, but there is room for further increase in the air volume of non-compliant rooms, the main unit will maintain the original setting operation. (3) If the room temperature compliance rate is not higher than the set value, but the room temperature is negative deviation, and the thermostats in compliant rooms that are not higher than the set percentage P% are in low wind mode or no wind mode, the main unit will maintain the original setting operation.

[0054] In this embodiment, the percentage of fan coil unit thermostats in low-wind or no-wind mode is P%, which is 80% by default.

[0055] In this embodiment, the setpoint range for the unit's outlet water temperature is [Tmin, Tmax], with a default value of [5℃, 10℃]. The adjustment increment for both increasing and decreasing the unit's outlet water temperature setpoint is dT. In this embodiment, the default adjustment value for the unit's outlet water temperature setpoint, dT, is 0.5℃. Regardless of whether the outlet water temperature is increased or decreased, the unit's outlet water temperature setpoint must remain within the range of [5℃, 10℃].

[0056] S14. Repeat S11~S13 according to the set cycle period T1. In this embodiment, the cycle period T1 is 20 minutes by default.

[0057] This embodiment combines criteria such as room temperature compliance rate, room temperature deviation, and airflow volume to determine when the actual building's cooling load demand is low and indoor cooling is excessive. In this case, the target outlet water temperature of the main unit can be increased promptly to achieve energy savings. Conversely, when the actual building's cooling load demand increases and indoor cooling is insufficient, the target outlet water temperature of the main unit can be decreased promptly to ensure indoor comfort. By comprehensively considering criteria including airflow volume, this embodiment adjusts the main unit's outlet water temperature to achieve airflow-water linkage while ensuring both indoor comfort and energy-saving effects.

[0058] Many air conditioning systems do not have cooling capacity meters installed. The decision to add or remove refrigeration units is entirely up to the maintenance personnel. However, it is difficult for people to grasp the actual demand. As a result, there are often situations where too many refrigeration units are turned on when the building's cooling demand is low, and too few refrigeration units are turned on when the building's cooling demand is high.

[0059] Therefore, such as Figure 2 As shown, it also includes the following steps:

[0060] S21. Read the total number of online thermostats, the number of fan coil units in operation, the actual room temperature, the set room temperature, the total number of main units, and the number of main units in operation;

[0061] S22. Calculate the fan coil unit operating rate, the main unit operating rate, and the room temperature compliance rate;

[0062] The fan coil unit operating rate can be calculated using two methods:

[0063] (1) Fan coil unit operating rate = number of fan coil units in operation / total number of fan coil units

[0064] (2) Fan coil unit operating rate = ∑(rated cooling capacity of fan coil units in operation) / ∑(rated cooling capacity of total installed fan coil units)

[0065] The host's power-on rate can be calculated using two algorithms:

[0066] (1) Host Activation Rate = Number of Hosts Activated / Total Number of Hosts

[0067] (2) Main unit uptime = ∑(rated cooling capacity of main units in operation) / ∑(rated cooling capacity of main units installed)

[0068] S23、(1)If the fan coil unit operating rate is greater than the host operating rate, and the room temperature compliance rate is less than the set value, and the number of host units in operation is less than the total number of host units, then add one unit;(2)If the fan coil unit operating rate is greater than the host operating rate, but the room temperature compliance rate is not less than the set value, then maintain the original number of units in operation;(3)If the fan coil unit operating rate is greater than the host operating rate, and the room temperature compliance rate is less than the set value, but the number of host units in operation is not less than the total number of host units, then maintain the original number of units in operation.

[0069] (1) If the fan operating rate is not greater than the main unit operating rate and the room temperature compliance rate is not less than the set value, then one unit shall be shut down. (2) If the fan operating rate is not greater than the main unit operating rate, but the room temperature compliance rate is less than the set value, then the original number of units shall be kept running.

[0070] S24. Repeat S21~S23 according to the set cycle period T2, and run synchronously with step S14. In this embodiment, the default value of the cycle period T2 is 30 minutes.

[0071] In addition, in this embodiment, the thermostat for cooling / heating modes has upper and lower temperature limits set by default: summer [22℃, 28℃], winter [16℃, 22℃]. The thermostat's operating mode is locked: cooling mode in summer and heating mode in winter.

[0072] The group control method in this embodiment combines the ventilator activation rate, main unit activation rate, room temperature compliance rate, and number of main units in operation to determine the building's load demand, and then adds or removes refrigeration units to achieve energy-saving operation of the system.

[0073] like Figure 3 As shown, it also includes the following steps:

[0074] S31. Read the thermostat's current power-on duration, actual room temperature, set room temperature, and thermostat's operating mode;

[0075] S32、(1)If the thermostat is powered on for longer than the set time T5 and the actual room temperature is less than the set temperature Tset, then the fan coil thermostat is reset to the set temperature Tset;(2)If the thermostat is powered on for longer than the set time T5 but the actual room temperature is not less than the set temperature Tset, then the fan coil thermostat remains in its original setting;(3)If the thermostat is powered on for longer than the set time T5, then the fan coil thermostat remains in its original setting.

[0076] In this embodiment, the fan coil unit's set temperature is automatically reset to the default cooling Tset of 24°C.

[0077] S33. Repeat S31~S32 according to the set cycle period T3, and run synchronously with steps S14 and S24. In this embodiment, the automatic temperature reset cycle T3 of the fan coil unit has a default value of 10 minutes, and the default value of the set time T5 is 20 minutes.

[0078] This embodiment can automatically reset the set temperature of the fan coil unit. Under the condition of meeting the user's need for rapid cooling when entering the room, the set temperature of the fan coil unit thermostat can be restored in time, avoiding energy waste caused by the set temperature being set too low for a long time.

[0079] like Figure 4 As shown, it also includes the following steps:

[0080] S41. Read the total number of online thermostats, the number of fan coil units in operation, the actual room temperature, the set room temperature, and the current fan speed of the thermostat.

[0081] S42. Calculate the deviation between the actual temperature and the set temperature of each room. (1) If the deviation of a room is greater than the positive deviation threshold, then issue an instruction to the thermostat of that room to increase the air volume. (2) If the deviation of a room is not greater than the positive deviation threshold and the deviation is less than the negative deviation threshold, then issue an instruction to the thermostat of that room to decrease the air volume. (3) If the deviation of a room is not greater than the positive deviation threshold and the deviation is not less than the negative deviation threshold, then maintain the original setting.

[0082] It should be noted that increasing the airflow specifically means increasing the airflow by one level, and decreasing the airflow specifically means decreasing the airflow by one level. If the airflow is already at a high level, it will not be increased further, or if the thermostat is specially calibrated, it will not be increased further; if the airflow is already at a low level or off, it will not be decreased further. This applies to specially calibrated rooms, such as offices and conference rooms.

[0083] S43. Repeat S21~S22 according to the set cycle period T4, and run synchronously with steps S14, S24 and S33. In this embodiment, T4 is 5 minutes by default.

[0084] This embodiment utilizes a group control method to actively adjust the airflow of fan coil units. By changing the airflow of the fan coil units, it increases the cooling capacity of rooms with insufficient cooling capacity and reduces the cooling capacity of rooms with excessive cooling capacity, thus promoting a balance between room cooling capacity and demand. Because the fan speed of some fan coil units is actively reduced, the power consumption of those units is decreased; simultaneously, the fan speed of fan coil units in rooms that do not meet cooling standards is increased, thereby increasing the cooling capacity of those units and improving the comfort of those rooms. This achieves the dual goals of energy saving and providing comfort.
