Description

Technical Field

[0001] The present invention relates to the technical field of combined air-conditioning control, and more specifically, to a combined air-conditioning anti-condensation control method and device, and the combined air-conditioning. Background Art

[0002] A modular air conditioner is an air conditioning system that integrates multiple functional modules, usually including cooling, heating, ventilation, dehumidification and other functions. These modules can work together to meet the air conditioning needs under different environmental conditions. The modular air conditioning system is flexible in design and can adapt to a variety of climates and usage scenarios. In the air conditioning system, when warm air with high humidity meets the cooling surface, water vapor condenses into water droplets to form condensation, which is the process of water vapor turning into liquid water due to the decrease in temperature when it contacts the cooling surface. Condensation in modular air conditioners will cause humidity to rise, which can easily cause indoor air to become humid, thus affecting indoor air quality. A humid environment is an ideal condition for the reproduction of mold and bacteria. The presence of condensation may promote the growth of mold and bacteria indoors, posing a threat to human health. Long-term condensation may cause damage to the building structure, such as walls, ceilings and floors may become damp, soft or moldy. Generally, the parameters of traditional combined air conditioners are relatively fixed. With fixed operation modes and parameters, it is difficult to flexibly respond to different environmental conditions, resulting in low efficiency. It lacks real-time monitoring and intelligent adjustment functions, and cannot make adaptive adjustments according to environmental changes, which easily leads to energy waste. It also lacks effective humidity and temperature control methods. Traditional combined air conditioners are prone to condensation under humid conditions, which increases the maintenance and health risks of the air conditioning system. Therefore, how to control condensation in combined air conditioners is of great significance. Summary of the invention

[0035] In order to enable persons skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and implementation modes.

[0036] In view of the problem that the existing combined air conditioners are prone to condensation and cannot be adjusted adaptively, resulting in increased humidity and further affecting the air quality, the present invention provides an anti-condensation control method and device for a combined air conditioner and a combined air conditioner, which solves the problem that the existing combined air conditioners are prone to condensation and cannot be adjusted adaptively, resulting in increased humidity and further affecting the air quality. The air conditioning function can be automatically adjusted in real time according to environmental conditions, thereby improving the intelligence and work efficiency of the air conditioning system.

[0037] like Figure 1 As shown, a method for controlling condensation prevention of a combined air conditioner comprises the following steps:

[0038] (1) Install temperature sensors at the combined air conditioner outlet and multiple locations indoors to monitor the air outlet temperature and indoor temperature in real time, and continuously compare the difference between the air outlet temperature and indoor temperature. If the temperature difference is greater than the preset threshold, start the adjustment program to reduce the temperature difference to prevent cold air from directly contacting warm and humid air and causing condensation;

[0039] (2) Install a wind speed sensor at the air outlet of the air conditioner to monitor the air outlet speed. According to the temperature difference identification results, adjust the fan speed and control the air volume. When the temperature difference is large, reduce the air volume to avoid condensation caused by rapid sinking of cold air.

[0040] (3) Install a temperature sensor at the outlet of the combined air conditioner, and use the data from the outlet temperature sensor to automatically adjust the temperature. The system automatically adjusts the refrigerant flow rate or the opening of the electronic expansion valve to finely adjust the outlet temperature and keep the difference between the indoor temperature and the outlet temperature within a safe range;

[0041] (4) Install a differential pressure sensor before and after the air inlet and outlet of the air conditioner to monitor the differential pressure before and after the filter, so as to determine the size of the wind resistance. When the wind resistance is detected to exceed the preset value, the system will issue a prompt to clean or replace the filter to ensure smooth air circulation and avoid inaccurate temperature control caused by reduced air volume;

[0042] (5) Install humidity sensors indoors to monitor indoor air humidity in real time. Based on the humidity sensor data, when the indoor humidity exceeds the set threshold, the intensity of the dehumidification mode is automatically increased to reduce indoor humidity and reduce the risk of condensation.

[0043] (6) Through precise control of the variable frequency compressor and electronic expansion valve and multi-point indoor temperature monitoring, the air volume and temperature of each air outlet are adjusted to ensure uniform indoor temperature distribution and avoid condensation caused by excessive cold air in some areas;

[0044] (7) Based on temperature and humidity control, the ventilation function is activated regularly or according to the data from the air quality sensor to introduce outside air and exhaust the hot and humid air in the room;

[0045] (8) Integrate all sensor data, analyze through the central control system, and predict the risk of condensation.

[0046] Specifically, the anti-condensation control of the combined air conditioner is carried out through the following steps: (1) temperature difference identification; (2) air volume control; (3) air outlet temperature adjustment; (4) filter wind resistance monitoring; (5) humidity control; (6) precise control of the variable frequency compressor and electronic expansion valve to ensure uniform indoor temperature distribution; (7) start the ventilation function according to the air quality sensor data, introduce external air, and exhaust the indoor hot and humid air; (8) predict the risk of condensation through analysis by the central control system.

[0047] It can be seen that the present invention provides a method for controlling condensation of a combined air conditioner, which compares the air outlet temperature of the air conditioner with the indoor temperature to identify the temperature difference and adjust the temperature to prevent cold air from directly contacting warm and humid air to cause condensation. The method solves the problem that the existing combined air conditioner is prone to condensation and cannot be adjusted adaptively, resulting in increased humidity and thus affecting air quality. The method can automatically adjust the air conditioning function according to environmental conditions in real time, thereby improving the intelligence and work efficiency of the air conditioning system.

[0048] like Figure 2 As shown, the present invention also provides an anti-condensation control device for a combined air conditioner, using the above anti-condensation control method, comprising:

[0049] The integrated analysis module is used to predict the risk of condensation. It uses the central processor to integrate all sensor data and uses intelligent algorithms for data analysis and processing. The algorithm is based on historical and real-time data of key parameters such as temperature, humidity, and air volume.

[0050] The interactive module is used to provide a user-friendly interactive interface to display the indoor environmental status in real time, including temperature, humidity, and air volume information. When a high condensation risk is detected, the interface prompts the user to take measures, including adjusting the indoor temperature and turning on ventilation.

[0051] Remote monitoring module, used to implement remote monitoring and control functions, through Wi-Fi or other wireless communication technologies, remotely view the air conditioner status, adjust settings through a smartphone app, and receive push notifications when the system predicts high risks.

[0052] The self-check and maintenance module is used to regularly perform self-check procedures to detect sensor functions, fan status, and filter status. When problems are found, it prompts maintenance or component replacement through the user interface to ensure system operating efficiency and anti-condensation performance.

[0053] The air valve adjustment unit is used to adjust the opening of the air valve to increase or decrease the air output of the combined air conditioner;

[0054] The water valve regulating unit is used to adjust the opening of the water valve to increase or decrease the cooling capacity of the combined air conditioner.

[0055] It can be seen that the anti-condensation control device for a combined air-conditioning system provided by the present invention can more effectively prevent the occurrence of condensation in the combined air-conditioning system through modular design, intelligent adjustment and real-time monitoring. Compared with the traditional combined air-conditioning system, it has higher flexibility, energy efficiency and healthy environment maintenance capabilities. It has modular design for different scenarios, uses sensor technology to monitor environmental conditions in real time, and automatically adjusts the system to improve the intelligence and efficiency of the air-conditioning system.

[0056] Accordingly, the present invention further provides a combined air conditioner, including the above-mentioned anti-condensation control method of the combined air conditioner and the anti-condensation control device of the combined air conditioner. In practical application, the anti-condensation control specifically includes the following steps:

[0057] Temperature sensor execution process: When the outdoor temperature drops significantly, cold air flows out of the air conditioner, forming a high temperature difference with the warm indoor air;

[0058] When the temperature sensor detects that the temperature difference exceeds the preset threshold, the system starts the temperature adjustment program to reduce the temperature difference by adjusting the airflow or modifying the cooling process to prevent the cold air from directly contacting the warm and humid indoor air and minimize the risk of condensation.

[0059] Wind speed sensor execution process: When the air conditioning system is running at full power, cold air is ejected from the air outlet at high speed; the wind speed sensor detects the high-speed airflow, and in response to the significant temperature difference, the system adjusts the fan speed to reduce the airflow rate, prevent the cold air from sinking quickly, and thus prevent the formation of surface condensation.

[0060] Temperature adjustment execution process: The air conditioner needs to maintain a comfortable indoor temperature without causing over-cooling. Temperature adjustment uses the outlet temperature sensor data to automatically adjust the refrigerant flow or electronic expansion valve to adjust the outlet temperature to ensure that the indoor temperature remains within a safe range and avoid condensation caused by over-cooling.

[0061] Pressure differential sensor execution process: As the usage time increases, the air filters in the air conditioning system accumulate dust, resulting in increased airflow resistance; the pressure differential sensor detects that the pressure difference on both sides of the filter exceeds the preset limit, and the system triggers an alarm, prompting the user to clean or replace the filter to ensure smooth airflow and avoid inaccurate temperature control due to reduced airflow.

[0062] Humidity sensor execution process: When the indoor air is humid, increasing the risk of condensation;

[0063] The humidity sensor detects that the indoor humidity has increased, and the system increases the dehumidification mode, reduces the indoor humidity, prevents the formation of surface condensation, adjusts the airflow or modifies the cooling process.

[0064] Central control system execution process: In different areas of the building, the indoor temperature distribution is uneven, resulting in overcooling in some areas; the central control system analyzes the temperature data of multiple sensors and adjusts the airflow and temperature of each air outlet to ensure uniform indoor temperature distribution and prevent local cold air accumulation and condensation.

[0065] Ventilation execution process: Without sufficient ventilation, indoor air quality deteriorates; the system activates ventilation mode based on air quality sensor data, introduces fresh outdoor air, exhausts humid indoor air, maintains a healthy indoor environment, and reduces the risk of condensation.

[0066] It can be seen that the combined air conditioner provided by the present invention can more effectively prevent the occurrence of condensation in the combined air-conditioning system through modular design, intelligent adjustment and real-time monitoring. Compared with the traditional combined air-conditioning system, it has higher flexibility, energy efficiency and healthy environment maintenance capabilities. It has modular design for different scenarios, uses sensor technology to monitor environmental conditions in real time, and automatically adjusts the system to improve the intelligence and efficiency of the air-conditioning system.

The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings.
