The invention discloses an air supply anti-explosion marine air conditioning system and a control method thereof. The air conditioner ventilation system comprises an independent air conditioner outdoor unit arranged outside a cabin of an explosion-proof place, an explosion-proof air conditioner indoor unit, an air inlet electric air door and an air exhaust mechanism, wherein the explosion-proof air conditioner indoor unit, the air inlet electric air door and the air exhaust mechanism are arranged in the cabin; the independent air conditioner outdoor unit comprises a refrigeration assembly andan electrical control box. The anti-explosion air conditioner indoor unit comprises an evaporator, a thermostatic expansion valve, an anti-explosion fan, an electric heater and a temperature sensor used for detecting the temperature of return air in the cabin of the anti-explosion position, the refrigeration assembly is communicated with the evaporator through a refrigerant pipeline penetrating through the cabin wall, and the thermostatic expansion valve is fixed to an inlet of the evaporator. The control method comprises a manual control mode and an automatic control mode, through the combined control of air conditioning and ventilation, the requirement for the storage temperature of the anti-explosion objects is met, long-time accumulation of flammable and explosive gas is avoided, the safety of the anti-explosion cabin is guaranteed, and the control method is high in automation degree, simple in logic setting, easy to operate and reliable in control.
