The following are detailed separately _。

In the present embodiment, description will be made from the viewpoint of an air-conditioning control method _。

Referring to fig. 1, an embodiment of the present invention provides a control method for a natural cooling air conditioner, applied to an air conditioner _。

Specifically, the control method includes steps 101 to 104 _。

101 _、 And acquiring the IT load power of the machine room.

In practical applications, due to the increasing density of electronic components used in modern electronic devices, thermal coupling between components occurs through conduction, radiation and convection. Therefore, thermal stress has become one of the most important factors affecting the failure of electronic components. For some circuits, reliability almost depends on thermal environment completely, and in order to achieve the purpose of expected reliability, the temperature of components must be reduced to a stable level that can be achieved practically, especially in a computer room built in a data center, since the computer room needs to calculate a large amount of background data, once a problem occurs, a problem occurs in the supported data service, and huge economic loss is brought to customers.

When the temperature of the machine room is too low, the IT equipment in the machine room cannot normally operate, and the normal operation of enterprise production is influenced to a certain extent. In addition to the low temperatures that can cause IT equipment to be inoperative, there can be problems with insulation, materials, batteries, etc. In detail, at low temperatures, the insulating material becomes hard and brittle, and the structural strength is also weakened. As for the bearing and the mechanical transmission part, the lubricating oil carried by the bearing and the mechanical transmission part is cooled and condensed, the viscosity is increased, and the phenomenon of viscosity is generated. When the temperature is too low, the solder with high tin content can be decomposed, so that the strength of electrical connection is reduced, and even faults such as desoldering, short circuit, condensation and the like occur. Therefore, for the production of a machine room, the use of the temperature and humidity controller plays a role of great weight.

Correspondingly, when the computer lab temperature is too high, also can lead to components and parts life-span to reduce to the probability of breaking down greatly promotes, and high temperature still can lead to the circumstances such as server shut down, server downtime and forced shutdown to take place, brings serious loss for the computer lab, with this, the temperature control of computer lab is especially important.

The method and the device for acquiring the IT load power in the computer room can automatically acquire the IT load power in the computer room, the IT load power is the current operation power of the IT equipment and can be the operation rate of the central controller, the larger the IT load power is, the higher the heating of the IT equipment caused by the operation is, the smaller the IT load power is, and the lower the heating of the IT equipment caused by the operation is.

The indoor temperature is the temperature in the machine room, the supply air temperature is the temperature of the supply air of the indoor air conditioner and is used for adjusting the indoor temperature, the cold-hot channel pressure difference is a parameter for adjusting the temperature, the IT load power is the power of the current operation of the IT equipment and can be the operation power of the central controller, the larger the IT load power is, the higher the heat generation of the IT equipment caused by the operation is, the smaller the IT load power is, the lower the heat generation of the IT equipment caused by the operation is, the unit of the IT load power can be watt (W), and watt is the power unit of international unit system, namely the amount of energy converted, used or dissipated (measured by Joule) per second.

102 _、 And determining the target refrigerating capacity according to the IT load power.

The IT load power can cause heating, so that the target cooling capacity required by the IT equipment under different IT load powers can be determined through experimental acquisition relative to the acquired IT load power, and IT is easy to understand that the larger the IT load power is, the larger the generated heating amount is, the larger the correspondingly required target cooling capacity is, and conversely, the smaller the IT load power is, the smaller the generated heating amount is, the smaller the correspondingly required target cooling capacity is, and the unit of the target cooling capacity can also be watt.

In some embodiments, the determining a target cooling capacity based on IT load power may include:

(1) Calculating corresponding heating value according to the IT load power;

(2) And determining the target refrigerating capacity of the unit according to the heating value.

The heating value unit can be joule (J), based on which, through experimental acquisition, under different heating values, in order to maintain the safe temperature of the machine room, the required refrigeration amount is corresponded to generate the preset refrigeration amount mapping relation, wherein the preset refrigeration amount mapping relation includes the relation that different heating values correspond to different refrigeration amounts.

Further, the target refrigerating capacity of the unit can be determined based on the current heating value according to the preset refrigerating capacity mapping relation.

103 _、 And acquiring a first ambient temperature outside the machine room.

The fluorine pump dual-cycle air conditioning system adopted in the embodiment of the application adopts an intelligent dual-cycle design, and when the outdoor temperature is lower in winter or transition seasons, the refrigerant pump (fluorine pump) is utilized to carry out outdoor cycle heat exchange on the refrigerant, so that an outdoor natural cold source is fully utilized; in summer or transition season when the outdoor temperature is higher, a compressor is adopted to perform compression cycle heat exchange on the refrigerant; the intelligent double-circulation design can greatly reduce the energy consumption of the air conditioner without starting a compressor for refrigeration within a certain time all year around, is also called as an intelligent double-circulation fluorine pump energy-saving air conditioner, and is called as a fluorine pump air conditioner for short according to the characteristics of the intelligent double-circulation fluorine pump energy-saving air conditioner.

It should be noted that the fluorine pump air conditioner includes three operation modes, which are a natural cooling mode, a hybrid mode and a compressor mode, and the operation efficiency of each mode is different.

Compressor mode (cooling mode): in summer, the special air conditioner for the machine room starts a refrigeration compressor to perform normal refrigeration, namely normal refrigeration circulation, and the electric quantity consumed in the refrigeration mode is the largest.

Natural cold mode (energy saving mode): when the outdoor temperature is lower than a set point, the operation is automatically switched to the fluorine pump energy-saving system, the safe and reliable operation of the machine room air conditioner all the year around is ensured, and the consumed electric quantity of the natural cooling mode is the least.

Mixed mode: when the outdoor environment temperature is slightly lower than the set temperature, the system is in a mixed mode, the compressor and the fluorine pump (refrigerant pump) work simultaneously, but the compressor operates in a variable frequency mode at the moment, the rotating speed is slow, the energy-saving effect is achieved, and the electric quantity consumed by the mixed mode is medium.

In the prior art, in the application process, because of the operation process of the fluorine pump air conditioner, the parameters of the mode switching are relatively solidified, the energy-saving effect can not be fully exerted when the IT load power is changed, or the operation mode of the fluorine pump air conditioner needs to be manually adjusted by an operator to improve the energy-saving effect, so that the problems of untimely adjustment or high operation cost can be caused.

Therefore, the first environment data outside the machine room, that is, the outdoor environment temperature, can be automatically acquired in the embodiment of the application, because the fluorine pump system is used for exchanging heat with the outdoor cold source in the natural cooling mode and the mixed mode, the outdoor environment temperature can affect the refrigeration effect of the natural cooling mode and the mixed mode, that is, the lower the outdoor environment temperature is, the larger the refrigeration capacity that the natural cooling mode can provide is, the larger the refrigeration capacity that the mixed mode can provide is, and conversely, the higher the outdoor environment temperature is, the smaller the refrigeration capacity that the natural cooling mode can provide is, the smaller the refrigeration capacity that the mixed mode can provide is, so that the mode selection needs to be performed in combination with the first environment data, and the specific selection mode please refer to the following steps.

104 _、 And determining the corresponding operation mode of the unit according to the first environment temperature and the target refrigerating capacity.

In a conventional case, the outdoor temperature (i.e. the first ambient temperature) may be represented as T, and T needs to satisfy a certain condition, and assuming that the range of T may be greater than minus 10 degrees, greater than 0 degrees, or greater than 5 degrees, since the refrigeration capacities corresponding to different operation modes are different, it may be understood that the refrigeration capacity output by the natural cooling mode is the minimum, the refrigeration capacity output by the mixed mode is greater than the natural cooling mode, and the refrigeration capacity output by the compressor mode is the maximum _。

Therefore, a first maximum cooling capacity that can be output in the natural cooling mode at the current first ambient temperature can be calculated, and a range smaller than the first maximum cooling capacity can be determined as a first cooling capacity range, that is, a range representing the cooling capacity that can be output by the unit in the natural cooling mode at the current first ambient temperature.

Similarly, since the fluorine pump system is also used in the hybrid mode, it can be correspondingly calculated that, when the compressor system operates in the frequency conversion mode at the first ambient temperature, based on the second maximum cooling capacity that can be output by the fluorine pump system, the range that is greater than the first maximum cooling capacity and smaller than the second maximum cooling capacity is determined as the second cooling capacity range, and the cooling capacity that is greater than the second cooling capacity range can only be satisfied by the compressor mode.

Therefore, the refrigerating capacity range of the target refrigerating capacity required by the current IT load power can be determined, the current operation mode of the unit is automatically determined, for example, when the target refrigerating capacity is in the first refrigerating capacity range, the natural cooling mode can meet the heating value of the current IT load power of the IT equipment, and the natural cooling mode is started; when the target refrigerating capacity is within the second refrigerating capacity range, the mixed mode can meet the heating value of the current IT load power of the IT equipment, the mixed mode is started, and when the target refrigerating capacity is larger than the second refrigerating capacity range, the natural cooling mode and the mixed mode can not meet the refrigerating requirement, and the compressor mode is started for refrigerating.

Therefore, the scheme is different from the scheme of only starting the corresponding operation mode of the unit and manually switching the corresponding operation mode of the unit through the indoor and outdoor temperature difference, the embodiment of the application uses the specific heat productivity of the IT load power of the IT equipment, and intelligently selects the current most appropriate operation mode of the unit to operate in combination with the outdoor temperature, repeated switching is avoided, the switching efficiency is greatly improved, and energy consumption is reduced.

From another perspective, when the indoor and outdoor temperature difference satisfies the natural cooling mode, in the related art, the natural cooling mode operation can be continuously maintained, however, if the IT load power of the IT device is larger, the heating amount is larger, and the required cooling capacity is also larger, because the cooling capacity of the natural cooling mode is limited, the cooling capacity cannot satisfy the actual requirement of the IT device, the IT device continuously heats up, and even goes down, according to the embodiment of the present application, when the IT load power of the IT device is detected to be larger, the adjustment (target cooling capacity increase) can be performed in time, when the target cooling capacity is larger than the first cooling capacity range, the natural cooling mode can be timely switched to the mixed mode for cooling, the temperature of the IT device is prevented from being too high, the occurrence of the downtime condition caused by mode selection with the dimension of a single indoor and outdoor temperature difference is avoided, and the safety and the operation stability of the IT device are better protected.

As can be seen from the above, in this embodiment, IT is possible to obtain the IT load power of the machine room; determining a target refrigerating capacity according to the IT load power; acquiring a first ambient temperature outside a machine room; and determining the operation modes corresponding to the unit according to the first environment temperature and the target refrigerating capacity, wherein the refrigerating capacities corresponding to different operation modes are different. The embodiment of the invention can combine the first environment temperature outside the machine room to intelligently adjust the air conditioning unit to select the most energy-saving operation state under different IT load power, thereby achieving the purposes of saving energy and reducing consumption and simultaneously ensuring the stable operation of the machine room, and greatly improving the control efficiency of the air conditioner.

The method described in the previous embodiment is further detailed below _。 It should be noted by those skilled in the art that the preset temperature parameters, the outdoor temperature data, etc. in the embodiments are only used for illustration of the embodiments, and should not be construed as limiting the embodiments _。

Referring to fig. 2, fig. 2 is another schematic flow chart of an air conditioner control method according to an embodiment of the present disclosure _。 The embodiment of the application is applied to a fluorine pump air conditioner, and the method flow can comprise the following steps:

step 201 _、 And acquiring the IT load power of the machine room.

The method and the device for acquiring the IT load power in the computer room can automatically acquire the IT load power in the computer room, the IT load power is the current operation power of the IT equipment and can be the operation power of the central controller, the larger the IT load power is, the higher the heating of the IT equipment caused by the operation is, the smaller the IT load power is, the lower the heating of the IT equipment caused by the operation is, and the unit of the IT load power can be watt.

Step 202, calculating corresponding calorific value according to the IT load power, determining the target refrigerating capacity of the unit according to the calorific value, and acquiring the first environment temperature outside the machine room.

The heating value of the IT equipment of the computer room can be calculated under the current IT load power, the unit of the heating value can be Joule (J), based on the heating value, the heating value can be acquired through experiments, under different heating values, in order to maintain the safe temperature of the computer room, the required refrigerating capacity is corresponded, so as to generate a preset refrigerating capacity mapping relation, and the preset refrigerating capacity mapping relation comprises the relation that different heating values correspond to different refrigerating capacities.

Further, the target refrigerating capacity of the unit can be determined based on the current heating amount according to the preset refrigerating capacity mapping relation.

It should be noted that the fluorine pump air conditioner includes three operation modes, which are a natural cooling mode, a mixed mode and a compressor mode, and the cooling capacity of each mode is different.

And wherein nature cold mode and mixed mode all use the fluorine pump system to carry out the heat transfer with outdoor cold source, therefore, outdoor ambient temperature can influence the refrigeration effect of nature cold mode and mixed mode, and outdoor ambient temperature is lower promptly, and the refrigerating output that nature cold mode can provide is bigger, and the refrigerating output that this mixed mode can provide is also bigger, and is opposite, and outdoor ambient temperature is higher, and the refrigerating output that this nature cold mode can provide is also smaller, and the refrigerating output that this mixed mode can provide is also smaller, with this, still need gather the first environmental data outside the computer lab, this outdoor ambient temperature promptly.

Step 203 _、 A first cooling capacity range of the natural cooling mode is determined based on the first ambient temperature, and a second cooling capacity range of the mixed mode is determined based on the first ambient temperature.

Wherein, because the refrigerating capacity corresponding to different operation modes is different, _。

therefore, the first maximum cooling capacity that can be output in the natural cooling mode at the first ambient temperature can be calculated, and the range that is smaller than the first maximum cooling capacity can be determined as the first cooling capacity range, that is, the range represents the cooling capacity that can be output by the unit in the natural cooling mode at the current first ambient temperature.

Similarly, since the fluorine pump system is also used in the hybrid mode, it may be correspondingly calculated that, when the compressor system operates in the frequency conversion mode at the first ambient temperature, based on the second maximum cooling capacity that can be output by the fluorine pump system, the range that is greater than the first maximum cooling capacity and smaller than the second maximum cooling capacity is determined as the second cooling capacity range, and the cooling capacity that is greater than the second cooling capacity range can only be satisfied by the compressor mode.

Step 204 _、 And when the target refrigerating capacity is detected to be in the first refrigerating capacity range, starting the natural cooling mode.

The method comprises the steps of determining the range of the refrigerating capacity of a target refrigerating capacity required by the current IT load power, automatically determining the current operation mode of a unit, and when the target refrigerating capacity is within the first refrigerating capacity range, indicating that the natural cooling mode can meet the heating value of the current IT load power of the IT equipment, and starting the natural cooling mode.

Furthermore, the operation of the outdoor fan is controlled according to the first target condensation pressure parameter, the operation of the indoor fan is controlled through the first indoor air quantity parameter, cold air at the corresponding temperature is output, the corresponding refrigerant can adjust the corresponding lift and flow operation according to the current refrigerating capacity requirement, the lift is the net energy added value obtained by the unit mass of fluid passing through the pump, the flow refers to the cooling liquid passing through the unit time, after that, the fluorine pump air conditioner can also dynamically feed back and adjust the indoor air quantity parameter according to the air pressure and the temperature difference of the machine room to control the flexible operation of the indoor fan, and dynamically feed back and adjust the operation of the outdoor fan and the refrigerant pump according to the air supply temperature.

And step 205, starting the mixed mode when the target refrigerating capacity is detected to be in the second refrigerating capacity range.

When the target refrigerating capacity is detected to be in the second refrigerating capacity range, the mixed mode can meet the heating value of the current IT load power of the IT equipment, and the mixed mode is started.

(5) Controlling the indoor fan to operate according to the second indoor air quantity parameter;

(6) And controlling the refrigerant pump to regulate the lift and flow operation according to the requirement of the refrigerating capacity.

Furthermore, the outdoor fan is controlled to operate according to the second target condensing pressure, the indoor fan is controlled to operate through the second indoor air quantity parameter, cold air with corresponding temperature is output, the compressor is controlled to operate at the first refrigerating capacity, the refrigerant pump and the compressor operate simultaneously, and then the fluorine pump air conditioner can also adjust the indoor air quantity parameter according to the air pressure of the machine room and the temperature difference dynamic feedback to control the indoor fan to operate flexibly, the operation of the refrigerant pump and the compressor is adjusted dynamically through the air supply temperature, and the continuous temperature control effect is achieved.

And step 206, when the target refrigerating capacity is detected to be larger than the second refrigerating capacity range, starting the compressor mode.

When the target refrigerating capacity is detected to be larger than the second refrigerating capacity range, the natural cooling mode and the mixed mode cannot meet the refrigerating requirement, and the compressor mode is started for refrigerating.
