The invention discloses an indoor temperature controller for preventing
dew formation of a cold radiating
system, and the
temperature control method thereof. The temperature controller includes a control module, a top surface
humidity detection unit, a top surface
dew-point temperature detection unit, a
room temperature detection unit, and a room
dew-point temperature detection unit. The
temperature control method is as follows: the control module obtains the top surface
humidity, the top surface dew-point temperature, the
room temperature and the room dew-point temperature on the basis of detection, and carries out
logic control on a
temperature control actuator. The temperature controller is assembled simply, and the temperature control
actuator can more accurately and rapidly respond on the basis of the
room temperature environment state, thereby realizing more comprehensive and better dew formation preventing function. The temperature control method provided by the invention ensures that the cold radiating
system can continuously and effectively prevent the dew formation state, and effectively avoid dew formation even at the
system starting initial stage, and moreover, compared with the method that ventilation
drying is performed before the system is started, the
logic control manner has the advantages of lower cost, facilitation of control, and better dew formation preventing effect.
