Indoor temperature controller for preventing dew formation of cold radiating system, and temperature control method thereof

Abstract

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.

Description

technical field [0001] The invention relates to cold radiation air conditioning technology, in particular to a non-condensing indoor temperature controller and a temperature control method for a cold radiation system. Background technique [0002] In cold radiant systems, when the water supply temperature is low or the indoor humidity is high, condensation is prone to condensation on the surface of the capillary radiant plate. Condensation can lead to mildew on the building envelope and reduce the useful life of the building. The mold produced by mildew can cause respiratory tract infections in humans, causing symptoms such as influenza and allergic reactions. Due to concerns about the above problems, the market application of cold radiant systems is greatly limited. How to effectively solve the problem of condensation on the surface of radiant panels in cold radiant systems is one of the key issues in the promotion of radiant cooling. [0003] In order to avoid condensati...

Problems solved by technology

However, this method is difficult to carry out precise control, and it is difficult to determine the ventilation and dehumidification time. When the supply of fresh air is insufficient, the effect of the above method of preventing condensation is unstable

[0005]Therefore, there is currently no suitable solution to the problem of condensation in cold radiant systems
