Abstract (en)
[origin: EP0117425A1] 1. A signal transmitter arrangement for controlling the defrosing of the air side of an evaporator means of a heat pump or the like comprising a sensing assembly consisting of a temperature sensing device for measuring the temperature on the surface of said evaporator means and a sensing device responding to the formation of frost or ice, said two sensing devices being coupled to a receiver for the transmission of signals, wherein said signal transmittal arrangement comprises a thermally conductive console (1) attachable to said evaporator means to which said sensing assembly (2) is connected, said temperature sensing device (3) being connected with said sensing assembly in a thermally conductive fashing, and wherein said sensing assembly comprises a photosensitive sensing device (4) constituting the second sensing device the optic axis of said photosensitive sensing device being aligned to an auxiliary matte black reflective surface (12) arranged vertically on said console, said reflective surface having a circular area of reflection (14) convex relative to said sensing assembly (2).
