Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 shows a flowchart of a method for controlling an air conditioning system according to an embodiment of the present invention. This air conditioning system includes: the air conditioning system comprises a central controller, a hydraulic module, a heat pump unit, a water purifier, an electric heating valve, an air inlet and outlet valve and a fresh air dehumidification module, wherein a dew point temperature controller, a pair of air inlet and outlet valves and a plurality of water pipelines are arranged in a target room, and the specific method for controlling the air conditioning system comprises the following steps:
step 101: the central controller receives the operation instruction.
In the embodiment of the invention, the air conditioning system is a temperature and humidity independent control air conditioning system, is applied to the indoor of a building, the general building comprises a plurality of rooms, the temperature and the humidity are controlled by a large-scale air conditioning system, each room is provided with a radiation type tail end, the radiation type tail end refers to a pipeline which is laid in each room and used for heating or cooling by using the radiation and heat transfer principle, and water is generally adopted in the pipeline as a cooling and heating medium, for example, floor heating installed in a household at present, or a fan coil and the like belong to the radiation type tail end. The air conditioning system in the embodiment of the invention comprises: the air conditioning system comprises a central controller, a hydraulic module, a heat pump unit, a water purifier, an electric heating valve, an air inlet and outlet valve and a fresh air dehumidification module, wherein the central controller is a control core of the whole air conditioning system, and all control logics, control data, state detection, fault alarm, equipment starting and equipment closing and the like are completed by the central controller when the air conditioning system is in normal operation. Because water is used as a cooling and heating medium, the air conditioning system needs a hydraulic module, generally uses tap water, but the tap water contains a lot of impurities and minerals, the pipeline can be rusted for a long time, and the pipeline is likely to crack and run when the pipeline is serious, so that the building can be immersed in water indoors and the loss is serious, therefore, a water purifier is generally arranged in the air conditioning system to purify the tap water, and the quality of the water is ensured not to influence the pipeline basically. The heat pump set in the air conditioning system is a device which can refrigerate and heat the air conditioner, the electric heating valve is a valve which is arranged on the pipeline and is used for opening or closing the pipeline, the central controller can control the opening degree of the electric heating valve and adjust the water quantity in the pipeline, the electric heating valves can be arranged in a plurality of numbers, the electric heating valves with different numbers can be arranged on the pipeline in each room according to the actual requirement, the air inlet and outlet valves are valves used for controlling the air inlet and the air outlet of the whole air conditioning system, if the air inlet and the air outlet valves are closed, the air inlet and the air outlet can not be carried out, the fresh air dehumidifying module is used for ensuring the fresh indoor air, because the doors and windows are in the closed state in the process of using the air conditioning system, the indoor air quality is reduced after a long time, the oxygen content can be lower, the waste gas content is higher, the discomfort of people can be easily caused, therefore, outdoor fresh air needs to be introduced, and the fresh air dehumidification module in the embodiment of the invention has the dehumidification function and the filtering and purifying function, so that the introduced fresh air is dry and high-quality air. When water is used as a cooling and heating medium, a water pipeline is easy to have a problem of condensation, the condensation refers to a phenomenon that when water vapor in air reaches a saturated state, supersaturated water vapor condensate in air begins to be separated out when the ambient temperature continues to drop, the humidity of the air gradually rises along with the drop of the ambient temperature when the water vapor content in the air is unchanged, when the temperature drops to a certain degree, the water vapor in the air can reach the saturated state, namely the air humidity is 100%, and when the ambient temperature continues to drop, the supersaturated water vapor condensate in the air begins to be separated out, and the temperature at which the condensation occurs is called condensation temperature and is called dew point for short. Dew condensation prevention is an important problem for pipes, because dew condensation may corrode or mildew. On the other hand, the condensation phenomenon causes the breeding of microorganisms such as indoor bacteria, fungi and the like, affects the indoor sanitary condition, and can form 'office rain' when the condensation is serious, thereby seriously interfering the normal work and life of indoor personnel. Therefore, dew point temperature controllers with different numbers can be installed on pipelines according to actual requirements in each room, the temperature and the humidity of the surrounding environment are detected in real time, and data are fed back to the central controller. The basic principle of the air conditioning system adopting water as a cooling and heating medium is that in summer, cold water with the temperature of A ℃ is introduced into a coil pipe buried in concrete, the return water temperature is B ℃, indoor heat is absorbed through the temperature difference (B-A) DEG C, in winter, hot water with the temperature of D ℃ is introduced into the coil pipe buried in the concrete, the return water temperature is E ℃, heat is radiated indoors through the temperature difference (D-E) DEG C, and when the whole system is refrigerated, the return water temperature is higher than the outlet water temperature; when heating, the water outlet temperature is higher than the return water temperature, indoor heat is absorbed or radiated to the indoor by using low temperature difference (generally 2 ℃), and the return water temperature and the water outlet temperature are not uniformly specified in China at present. When needing to use air conditioning system, must at first artificially carry out the instruction input, this instruction needs to set for air conditioning system's mode of operation is refrigeration or heats, and this instruction can be accomplished through air conditioning system's main control screen, engineer's screen or third party control screen, if have supporting APP, can also realize the instruction input through APP. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
Step 102: the central controller sets the indoor temperature and starts the dew point temperature controller, the electric heating valve and the hydraulic module.
In the implementation of the invention, after the air conditioning system receives the operation instruction, the number of the dew point temperature controllers in each room is detected, whether the dew point controller works normally is judged, and because various control targets which can be set in the central controller have upper limits, the general air conditioning system sets 1 dew point temperature controller participating in operation logic in a single room, a user can set the dew point temperature controllers in the central controller according to specific conditions, for example, if the control requirement of a certain room on the dew point problem is high, all the dew point temperature controllers in the room can be set into the central controller to participate in operation, the temperature is set on the central controller according to the temperature required by refrigeration or heating, and the dew point temperature controllers are opened at the same time, so that the dew point temperature controllers set in the central controller start to work, after the dew point temperature controllers are opened, the central controller opens the electric heating valves according to the conditions, and meanwhile, the hydraulic module is controlled to start working, and tap water heated or cooled by the heat pump unit is prepared to be conveyed into each pipeline and a fresh air unit pipeline carried by the fresh air module. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
Alternatively, referring to fig. 2, step 102 comprises:
step 102 a: if the air conditioning system is started for refrigeration for the first time, the central controller sets the indoor temperature to a factory default value, and opens dew point temperature controllers of other target rooms except a toilet and a kitchen.
In the implementation of the invention, if the air conditioning system is newly installed, the air conditioning system is refrigerated for the first time, the indoor temperature is automatically set to the factory default value of 23 ℃ by a general air conditioning system, certainly, after the air conditioning system is started, the user can reset the required indoor temperature according to the self requirement, meanwhile, the central controller can start all the dew point temperature controllers except the toilet and the kitchen, and does not start the dew point temperature controllers of the toilet and the kitchen because the environments of the kitchen and the toilet are wet, and the temperature is lower, and it is more easy to reach the condition that forms the dewing compared with other rooms, and also probably the air conditioning system just starts under the extreme condition, and the data that dew point temperature controller fed back just directly produces the warning, probably causes air conditioning system unable normal open, so when starting up for the first time, does not open dew point temperature controller. If heating is performed, in general, in winter, air is dry, and the condition for forming dew condensation is higher than that in summer, so that all the dew point temperature controllers can be turned on during heating, a user can manually turn off the dew point temperature controllers according to the requirement of the user, and the dew point temperature controllers of single rooms are manually controlled in the central controller to be not involved in operation. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
Step 102 b: otherwise, the central controller starts the dew-point temperature controller according to the previous set indoor temperature and the operation parameters of the previous dew-point temperature controller.
In the implementation of the invention, if refrigeration is not started for the first time, the central controller starts the dew point temperature controller according to the temperature set for the last time and the parameters of the dew point temperature controller started for the last time, and since the data of the previous normal operation is reserved, the normal operation of the air conditioning system can be ensured by starting according to the same parameters and settings as the previous time, and a user can modify the system according to own will. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
Step 102 c: if the operation instruction comprises a refrigeration instruction, the central controller closes the electric heating valves corresponding to the dew point temperature controllers in the toilet and the kitchen and opens the electric heating valves corresponding to the dew point temperature controllers in other target rooms except the toilet and the kitchen.
In the implementation of the invention, if the air conditioning system is used for refrigerating, the air is relatively humid in summer, and the humidity of the kitchen and the toilet is higher, so that the dew point temperature controllers of the kitchen and the toilet are closed when the air conditioning system is used for refrigerating, and the electric heating valves of the pipelines where the dew point temperature controllers are located are also closed, so that the reason for closing the dew point temperature controllers by the central controller is that the actual dew point temperature controllers are not closed but are running, and a user is likely to carelessly open the dew point temperature controllers when the user is in the kitchen and the toilet, and then the data fed back to the central controller by the dew point temperature controllers which are not opened can cause the central controller to generate wrong operation, so that the corresponding electric heating valves are also closed, so that no wrong data can be generated even if the dew point temperature controllers are opened, and the electric heating valves of the pipelines where the dew point temperature controllers are not located in the kitchen and the toilet are opened, the temperature of the kitchen and the toilet can still be ensured to reach the preset value. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
Step 102 d: if the operation instruction comprises a heating instruction, the central controller controls the electric heating valve according to the indoor temperature.
In the implementation of the invention, if the heating instruction is used in winter, the dew condensation condition is not easy to be satisfied, so the central controller can control the opening of the electrothermal valve according to the indoor temperature. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
Alternatively, referring to fig. 3, if the operation command includes a heating command, the central controller controls the electric heating valve according to the indoor temperature, and step 102d includes the following steps:
In the embodiment of the invention, the central controller detects the temperature of each room in real time, if the detected target room temperature is lower than the set indoor temperature, namely the operation instruction is a heating instruction, the indoor temperature set by the air conditioning system is set to 30 ℃ for example, and if the target room temperature is lower than 30 ℃, the opening degree of an electric heating valve of the target room is controlled to be increased, so that the target room temperature is increased to 30 ℃ which is preset; if the target room temperature is equal to 30 ℃, maintaining the opening degree of the electric heating valve; if the temperature of the target room is higher than 30 ℃, controlling the opening degree of an electric heating valve of the target room to be smaller; it should be noted that, when the air conditioning system does not have a fan coil and a coil electromagnetic valve, the air conditioning system can only adjust the indoor temperature by controlling the opening degree of the electric heating valve, and the larger the opening degree of the electric heating valve is, more hot water flows in the water pipe, and more heat is radiated indoors. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
In the embodiment of the present invention, if it is detected that the target room temperature is greater than or equal to the first temperature threshold, for example, the target room temperature is set to be 30 ℃ and the target room temperature is greater than or equal to 33 ℃, all the electrothermal valves in the target room are closed, and when the temperature drops to 30 ℃, the electrothermal valves are opened. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
The air conditioning system further includes: fan coil and coil solenoid valve, after central controller opened the electrothermal valve, step 102 still includes:
step 102 e: the central controller detects the number of fan coils and coil solenoid valves in the target room.
In the implementation of the invention, if the air conditioning system comprises the fan coil and the coil electromagnetic valves, the central controller detects the number of the fan coils and the coil electromagnetic valves in a target room, and the number of the fan coils and the coil electromagnetic valves is the same as that of the dew point temperature controller, and because various control targets which can be set in the central controller have upper limits, the number of the fan coils and the coil electromagnetic valves which participate in operation logic in a single room is set to be 1 in the common air conditioning system, a user can set the fan coils and the coil electromagnetic valves in the central controller according to specific conditions, for example, the temperature and humidity control requirement of a certain room is high, and all the fan coils and the coil electromagnetic valves in the room can be set. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
Step 102 f: and if the operation instruction comprises a refrigeration instruction and the indoor temperature set by the central controller, the central controller determines the target opening number of the coil electromagnetic valves of the target room according to the indoor temperature and the set indoor temperature and controls the fan coil to refrigerate.
In the implementation of the invention, if the operation instruction is a refrigeration instruction and the central controller sets the indoor temperature, for example, the refrigeration temperature is 23 ℃ (namely the central controller sets the indoor temperature), the central controller determines the target opening number of the coil electromagnetic valves of the target room according to the indoor temperature and the 23 ℃ and controls the fan coil to refrigerate, and finally the temperature of the target room reaches 23 ℃, so that the temperature of the target room can be independently adjusted. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
Step 102 g: and if the operation instruction comprises a heating instruction and the indoor temperature set by the central controller, the central controller determines the target opening number of the coil electromagnetic valves of the target room according to the indoor temperature and the set indoor temperature and controls the fan coil to heat.
In the embodiment of the invention, if the operation instruction is a heating instruction and the central controller sets the indoor temperature, for example, the heating temperature is 30 ℃ (namely the central controller sets the indoor temperature), the central controller determines the target opening number of the coil electromagnetic valves of the target room according to the indoor temperature and the 30 ℃ and controls the fan coil to heat, so that the temperature of the target room can reach 30 ℃ finally, and the temperature of the target room can be independently adjusted. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
It should be noted that if the fan coil and the coil electromagnetic valve are provided, the fan coil and the coil electromagnetic valve are controlled to adjust the temperature first, and if the temperature requirement is not met, the electrothermal valve is controlled to adjust the temperature.
Alternatively, referring to fig. 4, if the operation command includes a heating command and a set indoor temperature, the central controller determines a target opening number of the coil solenoid valves of the target room according to the indoor temperature and the set indoor temperature, and controls the fan coil to heat, and step 102g may include the following steps:
102g 1: and when the central controller detects that the indoor temperature of the target room is lower than the set indoor temperature, the central controller controls the coil electromagnetic valve and the fan coil of the target room to be opened.
In the embodiment of the invention, if the operation instruction comprises a heating instruction and a set indoor temperature, for example, the set target room temperature is 30 ℃, the central controller determines the opening number of the coil electromagnetic valves of the target room and controls the fan coil to heat under the condition that the detected target room temperature is lower than the set indoor temperature (for example, 28 ℃), and finally the target room temperature reaches 30 ℃, the coil electromagnetic valves are opened and the fan coil is controlled to heat, so that the indoor temperature can be quickly increased, if the coil electromagnetic valves and the fan coil are not arranged, the indoor temperature is increased only by the opening degree of the electrothermal valve, so that the indoor temperature is slowly increased, and the fan coil and the coil electromagnetic valves are more flexible and convenient to control compared with the electrothermal valve and are matched with the electrothermal valve to be used together, so that the indoor temperature can be better controlled. Under extreme circumstances, if the electrothermal valve is all opened to the maximum state, because various factors lead to indoor temperature can't reach second target temperature all the time, then open fan coil and coil solenoid valve and carry out the auxiliary heating, can adjust indoor temperature and rise to second target temperature. The embodiment of the present invention is not limited in detail, and may be set according to actual situations.
102g 2: and when the central controller detects that the indoor temperature of the target room is greater than or equal to the set indoor temperature and less than the first temperature threshold value, the central controller controls the coil electromagnetic valve and the fan coil of the target room to be closed.
In the embodiment of the invention, if the indoor temperature of the target room is set to be 30 ℃, the central controller detects that the indoor temperature of the target room is greater than or equal to 30 ℃ and is less than a first temperature threshold (for example, 33 ℃), for example, the indoor temperature of the target room is 31 ℃, the central controller controls the coil electromagnetic valve and the fan coil of the target room to be closed, and keeps the opening of the electrothermal valve, so that the indoor temperature of the target room is reduced and finally reaches the set indoor temperature of 30 ℃, and if the indoor temperature of the coil electromagnetic valve and the fan coil of the target room is not reduced to 30 ℃ after the coil electromagnetic valve and the fan coil of the target room are closed, the opening degree of the electrothermal valve of the target room is required to be controlled by. In addition, if the coil solenoid valve and the fan coil of the target room are already in the closed state, but the indoor temperature of the target room is higher than the set indoor temperature and lower than the first temperature threshold, the central controller needs to control the opening degree of the electric heating valve to be smaller to reduce the indoor temperature, and finally the indoor temperature reaches the set temperature (for example, 30 ℃).
