The present invention relates to a frost sensing and defrosting system for a refrigerating cycle by using a laser and, more specifically, to a frost sensing and defrosting system for a refrigerating cycle including an evaporator with a refrigerant pipe circulating a refrigerant and a heat absorption fin exchanging heat with the outside by being cooled by the refrigerant. The system includes: a fixing part fixed to and combined with a case of the evaporator; an adjusting part adjusting a position of a moving member by combining a support rod with the fixing part and installing the moving member on the support rod to be movable; a support part fixed and combined with the adjusting part to be extended to a part, in which the refrigerant pipe and the heat absorption fin are installed, and supporting a laser sensor part; the laser sensor part combined with the support part, sensing frost on the refrigerant pipe or the heat absorption fin by using a laser, and connected with a signal wire; a control part receiving a sensing signal of the frost, generated on the refrigerant pipe or the heat absorption fin, through the laser sensor part and then transmitting a defrosting signal to a defrosting device; and the defrosting device receiving the defrosting signal from the control part to remove the frost on the evaporator. |
