Fig. 1 is a flowchart of a method for air conditioning control provided by an embodiment of the present disclosure. Referring to fig. 1, an embodiment of the disclosure provides a method for controlling an air conditioner to control a central air conditioner of the water system, where the method may include:
s11, the controller obtains the set running temperature of the air conditioner and the space requirement information for adjusting the air conditioner capacity.
Here, the set operation temperature may be obtained according to an operation instruction of the user. Specifically, the user can send out an operation instruction for setting the running temperature of the air conditioner through the control terminal associated with the air conditioner. The control terminal may be an air conditioner remote controller, or may be a user intelligent terminal that establishes wireless communication with an air conditioner. Optionally, the wireless communication may include at least one or more of Wi-Fi communication, zigbee protocol communication, and bluetooth communication. The user intelligent terminal is, for example, a mobile device, a computer, or an in-vehicle device built in a floating car, or any combination thereof. In some embodiments, the mobile device may include, for example, a cell phone, smart home device, wearable device, smart mobile device, virtual reality device, etc., or any combination thereof.
Alternatively, the set operating temperature may be obtained based on an indoor environmental parameter of the space in which the air conditioner is located. Specifically, if the air conditioner maintains the correspondence between the indoor relative humidity and the set operation temperature and/or the correspondence between the indoor temperature and the set operation temperature, the set operation temperature of the air conditioner is adjusted under the condition that the indoor relative humidity and/or the indoor temperature meet respective preset conditions, so that the intelligent degree of the air conditioner is improved, and the operation flow of a user is reduced. Wherein, the preset condition of indoor relative humidity can be configured that the indoor relative humidity is more than or equal to 60% or less than or equal to 40%. The preset condition of the indoor temperature can be configured that the indoor temperature is more than or equal to 26 ℃ or less than or equal to 16 ℃ in winter; in summer, the indoor temperature is more than or equal to 27 ℃ or less than or equal to 22 ℃. Thus, the air conditioner is beneficial to ensuring the physical health of most users, and can avoid overload work of the air conditioner.
Optionally, the space requirement information for adjusting the air conditioning capability may include at least a space area of a space where the air conditioner is located and a current space temperature. Correspondingly, the space requirement information can be quickly and conveniently obtained through an infrared ranging sensor and a temperature sensor which are arranged in the space.
S12, the controller determines the current air conditioning capacity according to the set operating temperature and the space demand information.
Optionally, the controller determines the current air conditioning capacity according to the set operating temperature and the space requirement information, and may include: obtaining the space area of the space where the air conditioner is located and the current space temperature; and determining the current air conditioning capacity according to the set running temperature, the space area and the current space temperature. Therefore, the influence of the space demand information and the set running temperature of the air conditioner is integrated, and the current air conditioner capacity is more accurately determined, so that the energy consumption of the air conditioner is reduced while the use effect of the air conditioner is ensured, and resources are saved. Moreover, the double adjustment of space temperature and water inflow can be realized, and the use experience of a user is improved.
Alternatively, embodiments of the present disclosure may provide for a variety of implementations to obtain the current space temperature. The following is an example.
In one mode, under the condition that the air conditioner is determined to be started, the current space temperature can be continuously obtained, so that dynamic change of the current space temperature in the control process is obtained.
Alternatively, in the case where it is determined that the air conditioner is turned on, the current space temperature may be periodically obtained, for example, every 5 minutes, so as to reduce the data processing amount while maintaining the dynamic control.
In another mode, under the condition that the air conditioner is determined to be started, continuously obtaining the current space temperature, and when the current space temperature is equal to the set running temperature or a small error exists between the current space temperature and the set running temperature, periodically obtaining the current space temperature, and dynamically controlling the current air conditioning capacity.
Specifically, the current air conditioning capacity may be determined by:
Q＝S×K×(T s -T ao ) (1)
wherein Q is the current air conditioning capacity, S is the space area, K is the heat conductivity coefficient of air, T s To set the operating temperature, T ao Is the current space temperature.
Here, the thermal conductivity K of air is 0.024 w/m·degree.
S13, the controller determines the target water inlet temperature of the tail end of the air conditioner according to the current air conditioning capacity and the current water inlet temperature of the tail end of the air conditioner.
Optionally, the controller determines the target inlet water temperature of the air conditioner terminal according to the current air conditioning capacity and the current inlet water temperature of the air conditioner terminal, and may include:
wherein T is s For the target water inlet temperature T j For the current water inlet temperature, Q is the current air conditioning capacity, C is the specific heat capacity coefficient of water, and M is the flow coefficient.
Here, the specific heat capacity coefficient C of water has a value of 4200 joules/kg·celsius.
The flow coefficient M may refer to the number of flows of water through the valve under the conditions of prescribed test and with the pipe maintained at a constant pressure. Different valve products have different flow coefficients. In this embodiment, the flow coefficient M may have a value of 10 to 40.
Specifically, as can be seen from the combination of formulas (1) and (2), the current air conditioning capacity Q is related to the space area S, the thermal conductivity K of air, the set operating temperature of the air conditioner, and the current space temperature. Thus, the target intake water temperature may be determined as follows:
wherein T is s For the target water inlet temperature T j S is the space area, K is the heat conductivity coefficient of air, T is the current water inlet temperature s To set the operating temperature, T ao For the current space temperature, C is the specific heat capacity coefficient of water, and M is the flow coefficient.
S14, under the condition that the set running temperature is greater than or equal to the target water inlet temperature, the controller adjusts the water inlet flow at the tail end of the air conditioner according to the current water inlet temperature and the target water inlet temperature.
Optionally, the controller adjusts the water inflow of the air conditioner terminal according to the current water inflow temperature and the target water inflow temperature, and may include: determining a temperature difference between the current water inlet temperature and the target water inlet temperature; and (5) carrying out proportional integral adjustment on the inflow water flow according to the temperature difference value. Therefore, the water inlet flow can be quickly and accurately regulated according to the temperature difference, and the steady-state performance of the air conditioner control system is improved, so that the energy consumption of the air conditioner is reduced, and the resource waste is avoided.
Optionally, after the controller adjusts the inflow rate of the air conditioner end, the method may further include: determining that the running time length of the tail end of the air conditioner running under the adjusted water inflow is longer than or equal to the preset time length, and obtaining a new space temperature and a new water inflow temperature; and under the condition that the new space temperature is not matched with the set running temperature, carrying out flow regulation according to the new space temperature and the new water inlet temperature. Therefore, the water inflow at the tail end of the air conditioner can be adjusted according to the continuously-changed space temperature and the water inflow temperature, so that the double adjustment of the space temperature and the water inflow is realized, and the intelligent control logic of the air conditioner and the use experience of a user are improved.
Here, mismatch may mean that the new space temperature and the set operating temperature have a large error. In response thereto, the maximum allowable error may be ±1 ℃.
Alternatively, the preset duration may be 15 minutes to 60 minutes, preferably 30 minutes.
In summary, by adopting the method for controlling the air conditioner provided by the embodiment of the disclosure, the current air conditioning capacity is determined by obtaining the set running temperature of the air conditioner and the space requirement information for adjusting the air conditioning capacity, and the target water inlet temperature of the air conditioner terminal is determined according to the current air conditioning capacity and the current water inlet temperature of the air conditioner terminal; therefore, under the condition that the set running temperature is greater than or equal to the target water inlet temperature, the water inlet flow at the tail end of the air conditioner can be adjusted according to the current water inlet temperature and the target water inlet temperature, so that the accurate adjustment of the water flow is realized, the energy consumption of an air conditioning system is reduced, the resource waste is avoided, and the use experience of a user is ensured.
Optionally, the method for controlling an air conditioner may further include: and under the condition that the set running temperature is smaller than the target water inlet temperature, the controller controls a water valve for adjusting the water inlet flow to be closed. Thus, the energy-saving effect can be better realized, and the resource waste is avoided.
