The air channel of the evaporator fan 9 is perpendicular to the side surface of the evaporator 8, the evaporator fan 9 sucks the air, and the air flow passes through the evaporator 8 for convection heat exchange and then transmits the cold energy generated by the evaporator 8 to the air outlet 2.
The compressor 5, the condenser 6 and the evaporator 8 are sequentially connected into a closed refrigerating system through pipes, a certain amount of refrigerant is filled in the refrigerating system, when the refrigerating system works, the refrigerant is compressed into high-temperature and high-pressure gas through the compressor 5 and enters the condenser 6, the refrigerant gives off heat to the environment in the condenser 6, the temperature is reduced and is condensed into medium-temperature and high-pressure liquid under the action of the condenser air inlet machine 7, the pressure of the refrigerant is instantaneously released and the temperature is suddenly reduced through an expansion valve arranged on the pipes, the refrigerant is changed into an aerosol state from the liquid state, the refrigerant with reduced pressure and temperature enters the evaporator 8, the refrigerant releases cold air in the evaporator 8 and absorbs heat from the environment to be vaporized, and therefore a refrigerating effect is generated, and the refrigerant with increased temperature enters the compressor 5 to complete circulation.
