1. A method for pretreating an evaporator surface comprising:
a step of preparing an inoculation of malodorous microorganisms;
a step of preparing and pretreating an evaporator; and
a step of immobilizing the malodorous microorganisms on the evaporator surface,
wherein the step of preparing and pretreating the evaporator includes:
a step of closing and sealing a refrigerant pipe of the evaporator;
a step of treating a flowing stream of the evaporator of which the refrigerant pipe is closed and sealed; and
a step of drying the evaporator of which the flowing stream is treated, and
wherein the step of treating the flowing stream of the evaporator includes a step of installing the evaporator in a flowing stream treatment device and flowing tap water to accelerate odor reproduction by removing a surfactant component of the evaporator surface and aging a hydrophilic coating layer to facilitate attachment of microorganisms and gas adsorption.
