Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
Example 1
In this embodiment, as shown in fig. 1, there is provided a method for cutting an air conditioner room, including:
step 110, detecting whether a switching event exists in a plurality of machine rooms, and when the switching event is detected, determining that the machine room with the switching event is a machine room to be switched, and determining that the machine room without the switching event is a standby machine room.
It should be understood that the machine room refers to an air-conditioning machine room, and a plurality of air-conditioning machine rooms are arranged in a standby fluorine pump air-conditioning system, each air-conditioning machine room is provided with a plurality of units, and the condition that the temperature of the machine room rises rapidly in a short time easily occurs when the units are switched, so that the stable operation of the fluorine pump air-conditioning system is not facilitated. In this embodiment, the switching event refers to performing unit switching in a machine room, when the situation that the machine room has the switching event, that is, the machine room in which the switching event exists is detected as a machine room to be switched, and when the situation that the machine room does not have the switching event, that is, the machine room in which the unit switching is not performed is detected as a spare machine room, the machine room in which the switching event does not exist is determined.
And 120, calculating the cooling capacity of the cutting machine required by at least one machine room to be switched.
In this embodiment, since the temperature of the machine room to be switched rapidly rises in a short time when the machine room is switched, the cooling capacity of the machine room required when the machine room to be switched is the cooling capacity required for keeping the temperature in the machine room to be switched unchanged in a certain time when the machine room to be switched is switched. In some embodiments, the number of machine rooms to be switched in which the switching event exists may be one or more. For example, as shown in fig. 4, the number of air-conditioning rooms is four, namely, a 1# air-conditioning room, a 2# air-conditioning room, a 3# air-conditioning room and a 4# air-conditioning room, when the number of rooms to be switched is one, if the 1# air-conditioning room has a switching event, the 1# air-conditioning room is the room to be switched, and the 2# air-conditioning room, the 3# air-conditioning room and the 4# air-conditioning room are the standby rooms. When the number of the machine rooms to be switched is two, if the 1# air-conditioning machine room and the 3# air-conditioning machine room have switching events, the 1# air-conditioning machine room and the 3# air-conditioning machine room are both the machine rooms to be switched, and the 2# air-conditioning machine room and the 4# air-conditioning machine room are standby machine rooms.
In this embodiment, when the number of machine rooms to be switched is one, the cooling capacity of the machine needed when at least one machine room to be switched is calculated is the cooling capacity needed when the machine rooms to be switched are switched, and when the number of machine rooms to be switched is a plurality of machine rooms, the cooling capacity of the machine needed when at least one machine room to be switched is calculated is the sum of the cooling capacities needed when the machine rooms to be switched are switched.
And 130, calculating the standby cooling capacity generated when each standby machine room is loaded to full load.
In this embodiment, the number of the standby machine rooms is greater than or equal to 1, loading the standby machine rooms to the full load refers to increasing the refrigerating capacity of the units in the standby machine rooms to the maximum refrigerating capacity within the rated refrigerating capacity range of the units, and the standby refrigerating capacity generated when the standby machine rooms are loaded to the full load refers to the refrigerating capacity generated when the units in the standby machine rooms are loaded to the full load within the rated refrigerating capacity range of the units. Here, the calculated standby cooling capacity generated when each standby machine room is loaded to full load is only the maximum value of the standby cooling capacity which can be generated by the standby machine room.
In some embodiments, the refrigeration capacity of the cutter refrigeration capacity or the backup refrigeration capacity is calculated by the following relationship:
；
wherein Q is refrigerating capacity, C is specific heat capacity, m is mass, and DeltaT is temperature difference;
in this embodiment, the specific heat capacity of air is 1.005 kJ/(kg×k), the mass is equal to the product of density and volume, the air density is 1.29kg/m, the volume=the product of the indoor area of the machine room and the indoor height of the machine room, and Δt is obtained by subtracting the target temperature from the actual temperature of the machine room, and the cooling capacity or the standby cooling capacity of the cutting machine is obtained.
And 140, detecting whether the standby cooling capacity is greater than or equal to the cutter cooling capacity.
In this embodiment, since the temperature of the machine room to be switched rapidly rises in a short time when the machine unit is switched, the standby cooling capacity and the cooling capacity of the cutting machine need to be detected, and whether the standby cooling capacity is greater than or equal to the cooling capacity of the cutting machine is detected, so that the standby cooling capacity generated by the standby machine room can meet the cooling capacity required for keeping the temperature in the machine room to be switched unchanged in a certain time when the machine unit is switched, thereby keeping the stable operation of the air conditioning system of the fluorine pump.
And 150, when the standby cooling capacity is greater than or equal to the cooling capacity of the cutting machine, determining a standby machine room with the standby cooling capacity greater than or equal to the cooling capacity of the cutting machine as a candidate machine room, and controlling the machine room to be switched to be communicated with any one of the candidate machine rooms.
In this embodiment, in order to ensure that the temperature in the machine room to be switched does not change for a certain period of time when the machine set is switched, the standby machine room with the standby cooling capacity greater than or equal to the cooling capacity of the cutting machine is determined as the candidate machine room. In some embodiments, the number of the candidate machine rooms is one or more, and after determining the candidate machine rooms, the machine rooms to be switched are controlled to be communicated with any candidate machine room.
In one embodiment, after the step of determining that the backup machine room having the backup cooling capacity greater than or equal to the cooling capacity of the cutter is the candidate machine room, the method further includes: and the standby cooling capacity generated by loading the load of any candidate machine room to the candidate machine room is the same as the cooling capacity of the cutting machine, and the machine room to be switched is controlled to be communicated with the candidate machine room.
It should be understood that loading the load of any candidate machine room refers to loading the load of the candidate machine room to be higher than the current operation load, and when the machine set is switched, the cold energy of the cutting machine required by the machine room to be switched is known at this time, and when the standby cold energy of the candidate machine room loaded to the full load is greater than the cold energy of the cutting machine, if the operation load of the candidate machine room is directly loaded to the full load, the redundant cold energy is wasted, and the resource is wasted. Therefore, the standby cold quantity generated by loading the load of the candidate machine room to the candidate machine room is the same as the cold quantity of the cutting machine, so that the temperature in the machine room to be switched is kept unchanged for a certain time when the machine unit is switched, the stable operation of the fluorine pump air conditioning system is kept, and the waste of the refrigerating quantity is reduced. For example, the rated refrigerating capacity of the unit is 1000, and the machine room to be switched can meet the requirement only by 500 cold capacity, so that the load of the unit of the candidate machine room is increased to 50%, and the load of the unit of the candidate machine room is not required to be increased to 100%, namely, the full load state. In some embodiments, when the candidate machine room and the machine room to be switched are communicated, the standby cooling capacity generated by loading the load of the candidate machine room to the candidate machine room is the same as the cooling capacity of the cutting machine by opening a butterfly valve connected with the ring network of the machine room to be switched and opening a butterfly valve connected with the ring network of any one of the candidate machine rooms, and at the same time, the air convection device connected with the candidate machine room of the machine room to be switched is opened.
In some embodiments, when the number of the machine rooms to be switched is one, the cooling capacity of the cutting machine required by the machine room to be switched when the machine rooms to be switched are switched is calculated, the standby cooling capacity generated when each standby machine room is loaded to full load is calculated, when the standby cooling capacity is greater than or equal to the cooling capacity of the cutting machine, the standby machine room with the standby cooling capacity greater than or equal to the cooling capacity of the cutting machine is determined as a candidate machine room, and the machine rooms to be switched are controlled to be communicated with the candidate machine room. When the number of the machine rooms to be switched is multiple, the cold quantity of the cutting machine needed by the machine rooms to be switched when the machine rooms to be switched are switched is calculated, the standby cold quantity generated when each standby machine room is loaded to the full load is calculated, when the standby cold quantity is larger than or equal to the cold quantity of the cutting machine, the standby machine rooms with the standby cold quantity larger than or equal to the cold quantity of the cutting machine are determined to be candidate machine rooms, and the machine rooms to be switched are controlled to be communicated with the candidate machine rooms.
In the above embodiment, by calculating the cold energy of the cutting machine required when at least one machine room to be switched is cut, and calculating the cold energy of the standby machine rooms generated when each standby machine room is loaded to full load, when the cold energy of the standby machine room is greater than or equal to the cold energy of the cutting machine, the standby machine room with the cold energy of the standby machine room greater than or equal to the cold energy of the cutting machine is determined as the candidate machine room, and the machine room to be switched is controlled to be communicated with any one of the candidate machine rooms. Therefore, the occurrence probability of the condition that the temperature of a machine room is rapidly increased in a short time easily when the machine set is cut off is effectively reduced, and the stable operation of the fluorine pump air conditioning system is maintained.
In one embodiment, before the step of calculating the backup cooling capacity generated when each backup machine room is loaded to full load, the method further includes:
detecting whether each standby machine room is in a full load state;
when the standby machine room is in a non-full-load state, determining the standby machine room in the non-full-load state as a first standby machine room;
the step of calculating the standby cooling capacity generated when each standby machine room is loaded to full load comprises the following steps:
and calculating the standby cold quantity generated when each first standby machine room is loaded to full load.
It should be understood that the full load state refers to a state in which the refrigerating capacity of the unit in the standby machine room reaches the maximum refrigerating capacity, and when the standby machine room is detected to be in the full load state, it means that the standby machine room cannot generate additional refrigerating capacity. And the butterfly valve connected with the ring network is kept in a closed state, and the air convection device connected with the standby machine room in full load operation and the adjacent machine room is closed. In this embodiment, before the standby cooling capacity generated when each standby machine room is loaded to full load is calculated, the state of the standby machine room is detected, whether each standby machine room is in the full load state is detected, the standby machine room in the non-full load state is determined as the first standby machine room, and then the standby cooling capacity generated when each first standby machine room is loaded to full load is calculated.
In one embodiment, the step of controlling the communication between the machine room to be switched and any one of the candidate machine rooms includes:
determining that the standby machine room with the standby cold energy larger than the cold energy of the cutting machine is a second standby machine room;
selecting a second standby machine room closest to the machine room to be switched as the candidate machine room;
and controlling the machine room to be switched to be communicated with the candidate machine room.
In this embodiment, when the standby cooling capacity is greater than the cooling capacity of the cutting machine, the standby machine room with the standby cooling capacity greater than the cooling capacity of the cutting machine is determined as the second standby machine room, and at this time, the number of the second standby machine rooms may be one or more. It should be understood that when the number of the second standby machine rooms is one, the second standby machine room is the only candidate machine room, and the second standby machine room is also closest to the machine room to be switched, the machine room to be switched is controlled to be communicated with the candidate machine room. And when the number of the second standby machine rooms is multiple, selecting the second standby machine room closest to the machine room to be switched from the multiple second standby machine rooms as a candidate machine room, and then controlling the machine room to be switched to be communicated with the candidate machine room. And a specific priority strategy is adopted, namely a second standby machine room closest to the machine room to be switched is selected, an air convection device and a loading unit of the corresponding machine room are started, heat exchange of the machine room is enhanced, and the purpose of reducing overall temperature fluctuation is achieved. It should be noted that, this step is provided that when the standby cooling capacity is greater than or equal to the cooling capacity of the cutting machine, the switching machine room is controlled to be communicated with the candidate machine room no matter how many machine rooms are to be switched.
In one embodiment, after the step of detecting whether the backup cooling capacity is greater than or equal to the cutter cooling capacity, the method further includes:
when the standby cooling capacity is smaller than the cutter cooling capacity, detecting whether the sum of the standby cooling capacities generated when all the standby machine rooms are loaded to full load is larger than or equal to the cutter cooling capacity;
when the sum of the standby cold amounts generated when all the standby machine rooms are loaded to full load is larger than or equal to the cold amount of the cutting machine, selecting the minimum number of the standby machine rooms corresponding to the standby cold amounts larger than the cold amount of the cutting machine, and determining the minimum number of the standby machine rooms as the candidate machine rooms;
and controlling the machine room to be switched to be communicated with each candidate machine room.
In this embodiment, when the standby cooling capacity is smaller than the cooling capacity of the cutting machine, it means that the standby cooling capacity generated when any one of the standby machine rooms is loaded to the full load is smaller than the cooling capacity of the cutting machine, so it is required to detect whether the sum of the standby cooling capacities generated when all the standby machine rooms are loaded to the full load is greater than or equal to the cooling capacity of the cutting machine. When the sum of the standby cold amounts generated when all the standby machine rooms are loaded to the full load is detected to be larger than or equal to the cold amount of the cutting machine, the minimum number of the standby machine rooms meeting the condition that the sum of the standby cold amounts is larger than or equal to the cold amount of the cutting machine is calculated, and the minimum number of the standby machine rooms corresponding to the standby cold amounts larger than the cold amount of the cutting machine are selected to be determined as candidate machine rooms. For example, as shown in fig. 4, when the number of the rooms is four, the rooms are a 1# air-conditioning room, a 2# air-conditioning room, a 3# air-conditioning room, and a 4# air-conditioning room, the 1# air-conditioning room is the room to be switched, and the rooms are the spare rooms. When the required cold energy of the cutting machine of the 1# air-conditioning machine room is 800,2# air-conditioning machine room, the spare cold energy generated when the 1# air-conditioning machine room is loaded to the full load is 500,3# air-conditioning machine room, the spare cold energy generated when the 4# air-conditioning machine room is loaded to the full load is 500, the spare cold energy generated when the 4# air-conditioning machine room is loaded to the full load is 400, as can be seen from the above, the minimum number of the cold energy meeting the requirement that the sum of the spare cold energy is greater than or equal to the cold energy of the cutting machine is two, the 2# air-conditioning machine room and the 4# air-conditioning machine room or the 3# air-conditioning machine room and the 4# air-conditioning machine room can be selected as candidate machine rooms, and the 2# air-conditioning machine room and the 4# air-conditioning machine room are selected as candidate machine rooms because the 2# air-conditioning machine room is closest to the 1# air-conditioning machine room distance according to a specific priority policy, and the 2# air-conditioning machine room and the 4# air-conditioning machine room are controlled to be communicated, namely, the 2# air-conditioning machine room and the 4# air-conditioning machine room 430 connected with the looped network 410 are opened, the spare cold energy generated when the loads of the 2# air-conditioning machine room and the 4# air-conditioning machine room are loaded to the 2# air-conditioning machine room. If the number of the machine rooms to be switched is plural, the standby machine rooms meeting the minimum number of the machine rooms to be switched which is required when the sum of the standby cold amounts is larger than or equal to the cutting machines of the plural machine rooms to be switched are correspondingly selected, the standby machine rooms with the minimum number of the machine rooms to be switched which is required when the sum of the standby cold amounts is larger than or equal to the cutting machines of the plural machine rooms to be switched are determined as candidate machine rooms, and the corresponding candidate machine rooms are controlled to be communicated with the machine rooms to be switched.

The premise is still to select the standby machine room closest to the machine room to be switched and then calculate the standby cooling capacity of a plurality of standby machine rooms.

It should be understood that the states before and after the machine room switching units are all the states which are not communicated with each other, namely, the butterfly valve connected with the ring network is kept in a closed state, and the air convection device connected between the two adjacent machine rooms is closed. In this embodiment, when the sum of the standby cold amounts generated when all the standby machine rooms are loaded to the full load is smaller than the cold amount of the cutting machine, it means that the sum of the standby cold amounts generated when all the standby machine rooms are loaded to the full load cannot meet the requirement of keeping the temperature of one or more machine rooms to be switched unchanged for a certain time when the machine sets are switched, so that when the sum of the standby cold amounts generated when all the standby machine rooms are loaded to the full load is smaller than the cold amount of the cutting machine, the communication between the machine rooms to be switched and all the standby machine rooms is kept disconnected.
