Description

Technical Field

[0001] The invention relates to the technical field of air conditioning control, and in particular to a central air conditioning control method suitable for shopping malls. Background Art

[0002] A shopping mall refers to a market consisting of various stores gathered together. It is a large store with a large area and a relatively complete range of goods. The establishment of a shopping mall can realize centralized shopping, facilitate consumers, and provide consumers with a one-stop shopping environment. Generally, existing shopping malls will install central air-conditioning, which can ensure that the mall can provide a comfortable environment in different seasons. Even in summer, central air-conditioning can ensure that the indoor temperature is suitable to avoid the discomfort of direct cold wind. In addition, central air-conditioning can evenly adjust the indoor temperature through air supply, avoid local overheating or overcooling, and improve overall comfort.

[0003] However, the existing central air conditioning control in shopping malls only determines the temperature difference value for adjustment, and it is impossible to realize the zoning management of the central air conditioning inside the shopping mall, resulting in each air conditioner being under the same temperature and humidity conditions, which will increase energy consumption and affect the shopping experience of customers. Therefore, those skilled in the art provide a central air conditioning control method suitable for shopping malls to solve the problems raised in the above background technology. Summary of the invention

[0004] The purpose of the present invention is to provide a central air-conditioning control method suitable for shopping malls to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A central air conditioning control method applicable to a shopping mall comprises the following steps:

[0007] S1. System startup and initialization: Turn on the main power of the central air conditioner to put the air conditioner in standby mode, and perform initialization settings through the control panel or remote management system;

[0008] S2. Parameter setting and adjustment: Set the parameters of the central air conditioner according to the actual situation of the mall, and adjust the parameters of different central air conditioners according to different areas of the mall;

[0009] S3, Monitoring and Feedback: Sensors are installed in various areas of the mall to monitor the environmental parameters in the mall, and the monitored data is fed back to the system. The system compares and analyzes the current environmental parameters based on the preset algorithm and realizes its automatic regulation;

[0010] S4. Maintenance and care: Regularly perform maintenance and care on the central air conditioner to ensure that the central air conditioner is in good condition and extend its service life.

[0013] As a further solution of the present invention: the central air conditioner in S3 also has a fault diagnosis alarm function, which can automatically identify and report potential fault problems and immediately send out an alarm signal to facilitate timely maintenance.

[0014] As a further solution of the present invention: the steps of the automatic adjustment mode are:

[0015] A1: Sensors are used to detect parameters such as temperature, humidity, and air quality inside and outside the mall. These sensors transmit data to the central air conditioning controller;

[0016] A2: The controller receives the data from the sensor, compares it with the preset parameters, calculates the temperature difference that needs to be increased or decreased, and generates corresponding control signals to control the central air conditioner for automatic regulation.

[0017] As a further solution of the present invention: the parameters of the central air conditioner adjusted in S2 according to different areas of the shopping mall include crowd density, commodity type and time factor, wherein the crowd density can be divided into areas with dense crowds and areas with less crowds, commodity types such as temperature and humidity sensitive commodities need to control the temperature and humidity in the area, and the time factor is mainly to adjust the temperature and humidity in the morning, evening or night to adapt to the changes in the flow of people.

[0018] As a further solution of the present invention: the algorithm in S3 may include a temperature control algorithm and a humidity control algorithm, wherein the temperature control algorithm: △T=Tactual-Tsetting;

[0019] Where △T represents the difference between the actual temperature and the set temperature, Tactual is the current indoor temperature, and Tset is the target temperature set by the user;

[0020] The system adjusts the output of the cooling or heating system according to the value of △T. For example, when △T>0, the system may increase the cooling capacity; when △T<0, the system may reduce the cooling capacity or increase the heating capacity;

[0021] Humidity control algorithm: △RH = RH actual - RH setting;

[0022] Among them, △RH represents the difference between the actual humidity and the set humidity, RHactual is the current indoor humidity, and RHset is the target humidity set by the user;
