Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection. They can refer to a direct connection or an indirect connection through an intermediate medium, and they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.
[0018] For a dehumidifying fresh air system, it includes the necessary outdoor unit, dehumidifier, humidifier, PTC heating element, EC exhaust fan, EC intake fan, air valve, water valve, and all connecting pipes. The outdoor unit may include a primary unit, a deep dehumidification unit, or a multi-unit linkage structure.
[0019] like Figure 1 As shown, a terminal control device for a dehumidified fresh air system with variable control includes a main controller. The main controller houses an outdoor unit linkage module, a dehumidification module, a humidification module, an EC exhaust module, an EC fan module, an air valve module, a water valve module, a water temperature detector, and a PTC temperature controller. The outdoor unit linkage module is connected to the outdoor unit; the dehumidification module is connected to the dehumidifier; the humidification module is connected to the humidifier; the EC exhaust module is connected to the EC exhaust fan; the EC fan module is connected to the EC intake fan; the air valve module is connected to the air valve; the water valve module is connected to the water valve; the water temperature detector is installed in the water circuit to detect the water temperature; the PTC temperature controller is connected to the PTC heating element; and the main controller is connected to a control panel, which can be multi-functional. The EC exhaust fan and EC intake fan can be adjusted independently, and in conjunction with the opening of the air valve, the exhaust and intake air can be controlled.
[0020] The main controller is equipped with a wireless communication module, which enables remote communication and viewing, such as communicating with a mobile phone to achieve remote viewing.
[0021] The water valve is equipped with a temperature sensor, which can detect the water temperature at the valve.

[0025] Specific controls:
[0026] Dual dehumidification control: The primary unit provides chilled water for dehumidification, while the outdoor unit operates independently for deep dehumidification. The fan is linearly controlled, with humidity and temperature controls calculated first and then averaged. Based on the results, the dehumidification module determines whether to activate the dehumidifier.
[0027] Dual temperature control, automatically identifying summer and winter, and then determining the operating mode based on the current environment; variable frequency two-stage generator control; water valve control; air operation based on linear average temperature.
[0028] Flow control is determined by the number of valves opened, allowing for variable frequency operation of the water supply. Different flow rates are controlled by adjusting the opening degree of the water valves.
[0029] The humidifier operates independently with electrode wet curtains to humidify when the temperature is below the set temperature in winter under the floor heating mode.
[0030] The damper automatically switches its angle, adjusting its opening degree according to indoor environmental conditions and external humidity throughout the year. When indoor pollution is high, the opening is larger to achieve high-volume air exchange. Once indoor temperature and humidity are balanced and environmental conditions are good, the damper closes to 80%.
[0031] Dual temperature control / radiant cooling and heating, dual control, dew point tracking control, making it more stable and energy-efficient.
[0032] The main controller is equipped with a data processing chip, the MCU chip, which can monitor and process data, identify the current application environment, and provide users with precise control and a comfortable environment.
