Problems solved by technology
That is to say, most of the controllers of the central air-conditioning system currently used are the control of the water side and the control of the wind side separately, and the coordinated adjustment of the two cannot be achieved, and problems such as adjustment lag and inaccuracy are prone to occur.
[0005] The existing coil fan does not have the function of information transmission, so the system lacks corresponding effective information, so that the control system can only control the operation of the fan coil through a simple shutdown control method, and cannot perform effective intelligent control and management

The invention discloses a solenoid valve controlled fan coil self-adaptive energy-saving dehumidification controller. The controller is used for controlling freeze water of a fan coil and comprises aself-adaptive control circuit, an operation panel, a temperature acquisition module, a temperature acquisition module, a fan control loop and a water valve control loop. The self-adaptive control circuit makes a fan operate at low speed through a hardware circuit and a control algorithm to adjust a solenoid valve to conduct proportional connection and disconnection. The controller automatically outputs a control signal to the fan control loop and the water valve control loop by continuously acquiring return air temperature and relative humidity and conducting operation treatment through the hardware circuit and the control algorithm to cooperatively adjust the fan speed and connection and disconnection of the solenoid valve. Through self-adaptive adjustment, temperature fluctuation is small after the indoor temperature reaches to a stable value; moreover, water vapor in the air of an air conditioner room is effectively removed, so that the relative humidity is reduced to meet the requirement for comfort. In addition, compared with a traditional fan coil, the energy-saving effect of the solenoid valve controlled fan coil self-adaptive energy-saving dehumidification controller is improved remarkably.
Description
technical field [0001] The invention relates to the technology in the field of automatic control of heating and cooling air conditioners, in particular to a self-adaptive energy-saving dehumidification controller for a fan coil controlled by an electromagnetic valve. Background technique [0002] Fan coil unit is an ideal terminal product of central air-conditioning, and fan coil unit is widely used in hotels, office buildings, hospitals, commercial and residential buildings, and scientific research institutions. The working principle of the fan coil unit is to continuously recirculate the air in the room where the unit is located, so that the air is cooled and dehumidified in the surface cooler through the cold water coil, so that the temperature and humidity of the room meet the comfort requirements. In order to meet the requirements of people's work, life and craft production process, it is necessary to control the parameters such as indoor air temperature and humidity wi...
