Can high -efficient compound heat pump device who defrosts

The utility model belongs to the technical field of heat pump defrosting technique and specifically relates to a can high -efficient compound heat pump device who defrosts, including the installation box, the inside of installation box is equipped with the fin, and the fin installs on the surface of heat exchanger, the PLC controller is installed to the inside bottom surface of installation box, two electric telescopic handle and installation frame are installed to the inside top surface of installation box, the electric telescopic handle electric connection PLC controller. Through inserting electric telescopic handle and annular slab, temperature sensor is when the temperature of sensing the fin surface is less than the minimum of settlement like this for brush hair in the annular slab can remove the frost brush of fin surface knot, thereby makes the work that the fin still can be normal under the chilly condition of weather, makes the heat exchange efficiency of heat exchanger not receive the hindrance, has
