Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning control, and in particular to a feng shui linkage energy-saving group control method, system, equipment and medium. Background Art

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

[0003] In most projects, the air and water systems are controlled separately and independently, creating "information islands" where the air and water systems operate independently. However, the air and water systems are highly coupled, and this independent control approach leads to a mismatch between air supply and water supply, impacting building comfort (indoor temperature not meeting standards) and wasting energy. Summary of the Invention

[0004] The purpose of the present invention is to provide a Feng Shui linkage energy-saving group control method, system, device and medium to solve the problems existing in the prior art. To achieve the above purpose, the present invention solves the problem through the following technical solutions:

[0005] In a first aspect, the present invention provides a Feng Shui 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 room set temperature and the thermostat operating mode;

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

[0008] S13. If the room temperature compliance rate is higher than the set value, and the proportion of thermostats in the rooms that meet the temperature that exceeds the set value (P%) is in low-wind mode or no-wind mode, the main unit's outlet water temperature set point is increased. If the room temperature compliance rate is higher than the set value, but the proportion of thermostats in the rooms that meet the temperature that does not exceed the set value (P%) is in low-wind mode or no-wind mode, the main unit maintains 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 set temperature deviation upper limit is greater than the number of thermostats whose actual room temperature is lower than the set temperature deviation lower limit. If so, the room temperature is positively deviated, and the air volume of all non-compliant rooms cannot be further increased. In this case, the main unit water outlet set temperature is lowered;

[0010] S14. Repeat S11 to 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 increasing the air volume in the non-compliant room, the host 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 at this time, the thermostats in the compliant rooms are not higher than the set proportion P% in low wind mode or no wind mode, the host 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 turned on, the actual room temperature, the room set temperature, the total number of host units, and the number of host units turned on;

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

[0015] S23. If the fan coil unit on-time rate is greater than the host unit on-time rate, and the room temperature compliance rate is less than the set value, and the number of host units on is less than the total number of hosts, then add one unit; if the fan coil unit on-time rate is not greater than the host unit on-time rate, and the room temperature compliance rate is not less than the set value, then shut down one unit.

[0016] S24, repeat S21 to 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 startup rate is greater than the host unit startup rate, but the room temperature compliance rate is not less than the set value, the original number of units is kept in operation; if the fan coil unit startup rate is greater than the host unit startup 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 hosts, the original number of units is kept in operation.

[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 is maintained in operation.

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

[0020] S31, read the thermostat power-on time, actual room temperature, room set temperature and thermostat operation mode;

[0021] S32. If the thermostat is on for a period of time longer than the set time T5 and the actual room temperature is lower than the set temperature, the fan coil thermostat is reset to the set temperature. If the thermostat is on for a period of time longer than the set time T5 and the actual room temperature is not lower than the set temperature, the fan coil thermostat maintains the original setting. If the thermostat is on for a period of time shorter than the set time T5, the fan coil thermostat maintains the 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 coils turned on, the actual room temperature, the room set temperature, and the current wind 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 room thermostat to increase the air volume. If the deviation of a room is not greater than the positive deviation threshold and the deviation is less than the negative deviation threshold, send a command to the room thermostat to decrease the air volume. 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, 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] In a second aspect, the present invention provides a Feng Shui linkage energy-saving group control system, comprising:

[0028] Controlled equipment layer, including fan coil units and host computers;

[0029] The control execution layer includes a host controller and a thermostat. The host controller can communicate with the host and issue control instructions. The thermostat can communicate with the fan coil and issue control instructions.

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

[0031] In a third aspect, the present invention provides an 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, and the computer program is executed by the at least one processor so that the at least one processor can execute the Feng Shui linkage energy-saving group control method as described in the first aspect.

[0035] In a fourth aspect, the present invention provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the Feng Shui 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) The present invention combines the room temperature compliance rate, whether the room temperature has a positive deviation, and the air volume to determine when the actual building cooling load is small and the indoor cooling is excessive. The target outlet water temperature of the main unit can be promptly increased to achieve energy saving. At the same time, when the actual building cooling load increases and the indoor cooling is insufficient, the target outlet water temperature of the main unit can be promptly lowered to ensure indoor comfort. By comprehensively considering the determination conditions including the air volume, the present invention adjusts the outlet water temperature of the main unit in a timely manner, achieving Feng Shui linkage while ensuring indoor comfort and energy saving effects.

[0038] (2) The group control method of the present invention combines the judgment conditions such as the fan disk start-up rate, the host start-up rate, the room temperature compliance rate, and the number of host start-up units to judge the load demand of the building, and then add or reduce the refrigeration host units, thereby achieving energy saving in system operation.

[0039] (3) The present invention can automatically reset the fan coil unit's set temperature. Under the condition that the user's need for rapid cooling when entering the room for the first time is met, the fan coil unit's set temperature controller can be restored in time to avoid energy waste caused by the set temperature being adjusted too low for a long time.

[0040] (4) The present invention utilizes a group control method to actively adjust the air volume of the fan coil units. By changing the air volume 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, thereby promoting a balance between the cooling capacity supplied and the cooling capacity required in the rooms. Since the wind speed of some fan coil units is actively reduced, the power consumption of these fan coil units is reduced; at the same time, the wind speed of some fan coil units in rooms that do not meet the standards is increased, that is, the cooling capacity of these fan coil units is increased, thereby improving the comfort level of these rooms, achieving the dual goals of energy saving and providing comfort.

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

[0047] Example 1

[0048] like Figure 1 As shown, this embodiment provides a Feng Shui 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 room set temperature and the thermostat operating mode;

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

[0051] In this embodiment, the default temperature deviation thresholds are -1.5°C for the negative threshold and 1.5°C for the positive threshold. These can be set independently for each thermostat or globally. Set the lower temperature deviation limit to the room's set temperature + the negative threshold, and the upper temperature deviation limit to the room's set temperature + the positive threshold.

[0052] S13, (1) If the room temperature compliance rate is higher than the set value, and the thermostats of the rooms that meet the standards are in low wind mode or no wind mode with a ratio P% higher than the set value, the water outlet temperature of the host is increased; (2) If the room temperature compliance rate is higher than the set value, but the thermostats of the rooms that meet the standards are not in low wind mode or no wind mode with a ratio P% higher than the set value, the host maintains the original setting operation, and the water outlet temperature of the host remains 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 set temperature deviation upper limit is greater than the number of thermostats whose actual room temperature is lower than the set temperature deviation lower limit. If it is greater, the room temperature is a positive deviation, and the air volume of all non-compliant rooms cannot be further increased. At this time, the host water outlet set temperature is lowered; (2) If the room temperature compliance rate is not higher than the set value, and the room temperature is a positive deviation, but there is room for further increase in the air volume of non-compliant rooms, the host maintains the original setting operation; (3) If the room temperature compliance rate is not higher than the set value, but the room temperature is a negative deviation, and at this time, the number of thermostats in the compliant rooms that is not higher than the set proportion P% is in low wind mode or no wind mode, the host maintains the original setting operation.

[0054] In this embodiment, the proportion P% of fan coil thermostats that are turned on and in low wind or no wind mode is 80% by default.

[0055] In this embodiment, the unit outlet water temperature setpoint range is [Tmin, Tmax], with a default range of [5°C, 10°C]. The adjustment range for increasing or decreasing the main unit outlet water setpoint temperature is dT. In this embodiment, the default adjustment value for the unit outlet water temperature setpoint, dT, is 0.5°C. Regardless of whether the outlet water temperature is increased or decreased, the unit outlet water temperature setpoint must be within the range of [5°C, 10°C].

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

[0057] This embodiment combines criteria such as the room temperature compliance rate, whether the room temperature has a positive deviation, and air volume to determine when the actual building cooling load is low and the indoor cooling supply is excessive. This can be used to promptly increase the target outlet water temperature of the main unit to achieve energy savings. Furthermore, when the actual building cooling load increases and the indoor cooling supply is insufficient, the target outlet water temperature of the main unit can be promptly lowered to ensure indoor comfort. By comprehensively considering criteria including air volume, this embodiment allows for timely adjustment of the outlet water temperature of the main unit, achieving Feng Shui linkage while ensuring indoor comfort and energy savings.

[0058] Many air-conditioning systems are not equipped with cooling capacity meters. The decision to add or reduce cooling units is entirely determined by the operation and maintenance personnel. However, it is difficult for people to understand the actual demand situation. As a result, it is often the case that when the building requires less cooling capacity, too many cooling units are turned on; and when the building requires more cooling capacity, not enough cooling units are turned on.

[0059] For this reason, Figure 2 As shown, the following steps are also included:

[0060] S21, read the total number of online thermostats, the number of fan coil units turned on, the actual room temperature, the room set temperature, the total number of host units, and the number of host units turned on;

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

[0062] There are two algorithms for calculating the fan coil unit operating rate:

[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 that are operating) / ∑(total installed rated cooling capacity of fan coil units)

[0065] There are two algorithms for calculating the host uptime:

[0066] (1) Host startup rate = number of hosts in operation / total number of hosts

[0067] (2) Host operating rate = ∑(rated cooling capacity of the hosts that are powered on) / ∑(total installed rated cooling capacity of the hosts)

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

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

[0070] S24, repeat S21 to S23 according to the set cycle period T2, and execute 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 upper and lower temperature limits set by the thermostat for cooling / heating mode are: [22°C, 28°C] in summer, [16°C, 22°C] in winter. The thermostat operation mode is locked, locking the cooling mode in summer and the heating mode in winter.

[0072] The group control method of this embodiment combines the judgment conditions such as the fan disk startup rate, the host startup rate, the room temperature compliance rate, and the number of host startup units to judge the load demand of the building, and then add or reduce the number of refrigeration host units, thereby achieving energy saving in system operation.

[0073] like Figure 3 As shown, the following steps are also included:

[0074] S31, read the thermostat power-on time, actual room temperature, room set temperature and thermostat operation mode;

[0075] S32, (1) If the current power-on time of the thermostat is longer than the set time T5, and the actual room temperature is less than the set temperature value Tset, the fan coil thermostat is reset to the set temperature Tset; (2) If the current power-on time of the thermostat is longer than the set time T5, but the actual room temperature is not less than the set temperature value Tset, the fan coil thermostat maintains the original setting operation; (3) If the current power-on time of the thermostat is not longer than the set time T5, the fan coil thermostat maintains the original setting operation.

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

[0077] S33, repeat S31-S32 according to the set cycle T3, and run synchronously with steps S14 and S24. In this embodiment, the fan coil temperature setting automatically resets the cycle T3, the default value is 10 minutes, and the set time T5 default value is 20 minutes.

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

[0079] like Figure 4 As shown, the following steps are also included:

[0080] S41, read the total number of online thermostats, the number of fan coils turned on, the actual room temperature, the room set temperature, and the current wind 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, send a command to the room thermostat 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, send a command to the room thermostat 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, maintain the original setting.

[0082] It should be noted that increasing the air volume specifically means increasing it by one level, while decreasing it specifically means decreasing it by one level. If the air volume is already at a high level, the system will not increase it, or if the thermostat is specially calibrated, the system will not increase it. If the thermostat is already at a low level or is shut down, the system will not decrease it. Specially calibrated rooms, such as offices and conference rooms, are suitable.

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

[0084] This embodiment utilizes a group control method to proactively adjust the air volume of fan coil units. By varying the air volume of the fan coil units, the cooling capacity of rooms with insufficient cooling capacity is increased, while that of rooms with excess cooling capacity is reduced, thereby balancing the cooling capacity supplied and demanded. By proactively reducing the air speed of some fan coil units, the power consumption of these units is reduced. Simultaneously, the air speed of some rooms that do not meet the required cooling standards is increased, thereby increasing the cooling capacity of these units and improving the comfort level of these rooms. This achieves the dual goals of energy conservation and comfort improvement.
