The invention discloses an ultralow-temperature air energy heat pump set and a using method thereof, and solves the technical problems that in the prior art, a condenser of the existing air energy heat pump set can not normally defrost and has poor defrosting effect under ultralow temperature condition, an air energy heat pump water heater or heating air conditioner can not normally work when frosting is severe, and the like. The ultralow-temperature air energy heat pump set has the advantages that the structure is simple, the condenser can automatically defrost and has good defrosting effect, and the energy consumption is reduced. The ultralow-temperature air energy heat pump set is characterized in that: a condenser temperature sensor and multiple groups of heating fins are arranged on the condenser of the device, the heating fins are parallel to the fins of the condenser and are fixed on a copper pipe of the condenser, a water temperature sensor is arranged inside a water tank, a compressor, the heating fins, the condenser temperature sensor and water temperature sensor are connected with an external power supply through a controller, and the controller is used for automatically controlling the opening / closing of the heating fins according to the temperature measured by the condenser temperature sensor and the water temperature sensor.

The invention relates to the technical field of heat exchangers, and discloses a heat exchanger capable of automatically defrosting or deicing. The heat exchanger comprises a tube bank and fins. A refrigerating medium can be introduced into the tube bank, the fins are arranged on the outer wall of the tube bank, and the heights of the fins extend in the radial direction of the tube bank. Each fincomprises a first heat conduction part and a second heat conduction part that are sequentially connected to the tube bank, and the heat conductivity coefficient of the second heat conduction part is smaller than that of the first heat conduction part and the tube bank. The outer surface of the first heat conduction part and the outer surface of the tube bank are each coated with a micron-scale ornano-scale hydrophobic layer, and the hydrophobic layers are hydrophobic coatings or hydrophobic oil films. According to the heat exchanger capable of automatically defrosting or deicing, the heat conductivity coefficient of the second heat conduction part is relatively low, frost or ice on two sides of the tube bank can be separated under a cold release working condition, the tube bank is prevented from being annularly wrapped by the frost or ice, and meanwhile, a frost layer or an ice layer can automatically fall off under the action of gravity through the hydrophobic coatings or the hydrophobic oil films, and a heating and defrosting process can be omitted, and the cold release heat exchange efficiency of the heat exchanger is improved.

The invention discloses an automobile defrosting and defogging rod, which comprises a rod body, a cover and a rubber pad, wherein the rod body is in a cylinder shape with the smooth surface, the inside of the rod body is hollow, one end of the rod body is provided with a water filling opening, a threaded body is arranged on the inner wall at the water filling opening part of the rod body, one end of the cover is provided with a handle, the other end of the cover is provided with the rubber pad, and the cover is matched and connected with the threaded body. The automobile defrosting and defogging rod has the advantages that the use is simple, safety and effectiveness are realized, more importantly, the energy is saved, the environment is protected, heat transferred by hot water can be used for fast removing frost and fog on automobile windows, the residue temperature can also be used for heating, in addition, the size is small, the carrying is convenient, and the automobile defrosting and defogging rod can be held in the hand or be placed in a bag.

Automatic defrost technology for refrigeration equipment, in particular, defrosting refrigeration equipment by acceleration defrosting sublimation effects in refrigeration chambers in continual operation below the freezing point of water. Useful for refrigeration equipment for storage of vaccines and other products having storage temperatures ranging from −58 degrees Fahrenheit and 5 degrees Fahrenheit.
