Description

Humidity controller for fan coil unit

The present invention relates to a humidification control device of a fan coil unit. More specifically, the heating value of the heating heater and the driving fan of the humidifying device used to control the humidity in the indoor air can be determined by the user's humidity setting value and the current indoor humidity. Comparing the detection values with each other and automatically variable in response to the results it was invented to maintain the indoor air at the desired humidity at all times.

Most fan coil unit humidifiers include: a water tank in which humidifying water is stored in a housing having a discharge part; A filter for filtering dust contained in the air when the indoor air is sucked by the blowing fan; A blowing fan for sucking indoor air and forcibly discharging it back into the room together with the water molecules; A heat exchanger configured to perform heat exchange with air when air and water molecules are discharged to the outside by the blower fan to maintain the temperature of the indoor air; A drain pan for discharging condensate generated due to heat exchange in the heat exchanger to the outside; An operation unit including a power switch for determining whether to drive the humidifier itself, a strong and weak selection switch for allowing a user to arbitrarily select the driving amount of the blower fan; And a control unit for controlling the driving speed of the blower fan and the like in response to the key signal input from the operation unit.

However, since the fan coil unit humidifier having such a configuration is supplied with moisture by natural convection, it takes a long time to increase the humidity of the indoor air.

Therefore, recently, in the fan coil unit humidifier, a heat transfer heater is installed in the fan coil unit humidifier to increase the amount of vaporization so that the humidification operation can be performed in a faster time by heating the water of the water tank to the heat exchanger through the tube.

Therefore, the fan coil unit humidifier having such a configuration can increase the amount of humidification compared to the fan coil unit humidifier as described above, thereby reducing the humidification time, but the heat generation amount of the electric heater and the driving speed of the blower fan. Regardless of the current humidity is always driven in response to the amount and speed selected by the user through the operation unit has a disadvantage in that the indoor indoor humidity does not maintain the desired humidity can not maintain a comfortable indoor environment.

The present invention was devised to solve such problems in the related art, and the humidity value set by the user and the current humidity of the electric heating heater heating amount and the driving fan of the humidifier used to control the humidity in the room By comparing the detected values with each other, if the current humidity is less than the set humidity, the electric heater and blower fan will be driven weaker than the current one, and if it is vice versa, the user can always keep the indoor air at the desired humidity. It is an object of the present invention to provide a humidification control device of a fan coil unit that can be maintained.

A humidity sensor for detecting a change in humidity in the room with an electrical signal; An A / D converter for converting an analog humidity detection signal input in real time from the humidity sensor into digital data and transmitting the same to a controller; A humidity setting unit is installed to allow a user to set an indoor humidity to a desired humidity, and the control unit is configured to drive a blower fan and an electric heater in response to a key signal of an operation unit, and the current room inputted through the A / D converter. If the current humidity is lower than the set humidity, the control signal for increasing the driving speed and the heating value of the blower fan and the heating heater to a predetermined value is compared with the output data of the humidity setting part installed by the user. If it is generated and the current room humidity is higher than the set humidity, it can be achieved by generating a control signal for lowering the driving speed and the heat generation amount of the blower fan and the heating heater to a certain value.

Therefore, the indoor humidity can be always maintained at the humidity set by the user, thereby maintaining a pleasant indoor environment at all times, as well as greatly improving the merchandise and reliability of the product.

If the current room humidity is lower than the set humidity compared with the output data of the humidity setting unit 11 installed by the user, the blower fan 5 and the heat heater 6 are given priority over the key signal of the operation unit 1. Control signal to raise driving speed and heating value to a certain value, and control to lower driving speed and heating value of blower fan (5) and thermal heater (6) to a certain value when the current indoor humidity is higher than the set humidity. It is characterized by generating a signal.

Referring to the operation and effect of the device of the present invention configured as described above are as follows.

First, the user 'turns on' the power switch installed on the operation unit 1 outside the humidifier main body 14 (not shown), and operates the airflow and humidification amount strong, medium, and weak selection switches appropriately. When the air blowing amount and the humidification amount are selected, the control unit 2 recognizes this and generates a predetermined control signal to the blowing fan drive unit 3 and the heat transfer heater drive unit 4 so that the blower fan 5 and the heat transfer heater 6 are used. Will be driven in response to the selected level.
