Heating control device and heating control method for condensation resistance of refrigerating vertical beam of side-by-side combination refrigerator

Abstract

The invention relates to a heating control device and a heating control method for condensation resistance of a refrigerating vertical beam of a side-by-side combination refrigerator. The heating control device comprises a heater positioned on the vertical beam, an environmental temperature sensor and a control unit, wherein the environmental temperature sensor can output signals to the control unit according to collected environmental temperature values, and the control unit can output signals to control the heater to work. The control method can set the relative humidity as a constant value according to related condensation resistance applicable standards, and the control unit can control working modes of the heater with power as the constant value according to the environmental temperature values collected by the environmental temperature sensor. The heating control device and the heating control method adopt the low-cost environmental temperature sensor and a single environmental temperature parameter variable to control the condensation-resistant heater, thereby reducing cost, simplifying procedures and simultaneously guaranteeing stability and reliability of a system. By means of the heating control device and the heating control method, humidity corresponding to standard dew-point temperature can be set as a safety constant, thereby reducing the parameter viable and simplifying the control method.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to a heating control device and a control method for anti-condensation of refrigerating vertical beams of side-by-side refrigerators. Background technique [0002] Generally common French side-by-side computer refrigerator usually can design a vertical beam between its two refrigeration doors, the existence of this vertical beam can be convenient to the overlap joint and sealing of the door seal between two refrigeration doors. However, due to the thickness of the vertical beam itself and the thermal conductivity of the filling material in the middle, the surface temperature of the refrigerator is relatively low during normal cooling, and condensation is prone to occur. To prevent condensation on the surface, a heater is usually attached to the inner surface of the vertical beam. Its surface temperature rises. [0003] At present, general manufacturers adopt a con...

Problems solved by technology

[0007] Since the conditions of the product in actual use are changeable, such as the ambient temperature, humidity and the temperature of the room set by the user will have an important impact on the final result, and the control method of the humidity sensor has a great influence on the actual use. The effect also has a greater impact, so it is difficult to ensure that users are foolproof in actual use

Therefore, this method is not advisable in actual product anti-condensation design
