Air conditioning is a kind of electrical products that people can't get away with in modern people's office and home life. In the summer, air conditioners have the function of cooling, while in winter, air conditioners have the function of heating, the same composition, how air conditioning is achieved. What about the requirements? This has to start from the principle of refrigeration and heating of air conditioners, let's take a look!
Air conditioning refrigeration principle:
After the air conditioner is energized, the low-pressure steam of the refrigerant in the refrigeration system is sucked by the compressor and compressed into high-pressure steam and discharged to the condenser. At the same time, the outdoor air drawn by the axial fan flows through the condenser, taking away the heat released by the refrigerant, so that the high-pressure refrigerant vapor condenses into a high-pressure liquid. The high-pressure liquid is sprayed into the evaporator through the filter and the throttling mechanism, and is evaporated at a corresponding low pressure to absorb the surrounding heat. At the same time, the cross-flow fan allows air to continuously enter the ribs of the evaporator for heat exchange, and sends the exothermic and cooled air to the room. In this way, the indoor air continuously circulates to achieve the purpose of lowering the temperature.
Air conditioning heating principle:
Heat pump heating uses a compression condenser of the refrigeration system to heat the indoor air. When the air conditioner is in the cooling operation, the low-pressure refrigerant liquid evaporates and absorbs heat in the evaporator, and the high-temperature high-pressure refrigerant releases heat and condenses in the condenser. Heat pump heating is through electromagnetic reversal, the position of the suction and exhaust pipe of the refrigeration system is reversed. The indoor coil of the original refrigeration working evaporator becomes the condenser at the time of heating, so that the refrigeration system absorbs heat outside the room and releases heat to the room to achieve the purpose of heating.

Commonly, Hard ferrite is a type of ceramic Fe2O3,BaCO3 or SrCo3 compund material.The density of ferrite magnets about 5g/cm3, and they are divided to hard ferrite and soft ferrite.
They are both electrically nonconductive and ferrimagnetic.Of course,they also can as Construction Magnet. Hard ferrites have higher coercivity and higher remanence after magnetization. Ceramic magnets are cheap and widely used in household appliance such as refrigerator horseshoeshaped magnet, letric motors, teleconmmunication loud speaker,magnetic recording.etc.
Soft Ferrite Magnet is a sort of Fe2O4,Zinc or Nickel compund material.They have a low coercivity thus called soft ferrites. Because of their comparatively low losses at high frequencies.
They are extensively used in the cores of RF tranformers and inductor in applications of AM redios.
