Description

Industrial mobile air conditioner The present invention relates to an industrial portable air conditioner, and more specifically, to an industrial portable air conditioner that seeks to increase the cooling effect by separating the space between the cold air generating section and the hot air generating section, improves cooling performance by increasing the cold air discharge volume and cold air discharge flow velocity, and enables continuous supply of cold air without discharge resistance even during defrosting. Generally, industrial portable air conditioners consist of a compressor, condenser, expansion valve, evaporator, motor, and fan. Therefore, industrial portable air conditioners generate cold air by lowering the surrounding temperature. This is achieved by changing the pressure using a compressor to condense the gaseous refrigerant into a liquid in the condenser, and then lowering the pressure through an expansion valve to allow the liquid coolant to vaporize back into steam inside the evaporator, thereby absorbing heat. In this way, heat is absorbed when the liquid liquefies into a gas in the evaporator, and released when the gas condenses into a liquid in the condenser. Thus, industrial portable air conditioners achieve a cooling effect through the heat of vaporization. Meanwhile, in household air conditioners, the heat-generating condenser process is located outdoors, so only cold air remains indoors. However, in industrial portable air conditioners, the outdoor unit (condenser) is placed inside the same air conditioner body along with the evaporator, allowing for the simultaneous generation of cold and hot air within the same space. Consequently, the separation of the cold and hot sections and the smooth discharge of cold air become critical. However, conventional technology suffers from reduced cooling efficiency because the separation of the cold and hot sections is not achieved. Additionally, there is a disadvantage in that cold air cannot be continuously supplied because the power is cut off during defrosting. The technology forming the background of the present invention is Korean Published Patent No. 10-2024-0053296 (Patent Document 1), which proposes a 'high-efficiency condensate discharge device for industrial air conditioners.' This device is designed so that when condensate generated in an evaporator is transferred to a collection tank equipped with a heat dissipation means in which the heat dissipation pipe of the condenser is extended, the condensate absorbed by the absorbent material is evaporated using the high heat of the condenser by an evaporation means installed in the collection tank, positioned behind the heat dissipation means, and equipped with an absorbent material having a height greater at the rear than at the front. Another technology that forms the background of the present invention is Korean Registered Patent No. 10-2605116 (Patent Document 2), which proposes an 'industrial integrated air conditioner.' This design lowers the temperature of the air by vaporizing it into water before it passes through the evaporator of the air conditioner to increase cooling efficiency, and lowers the high temperature by having the hot air from the condenser pass through an evaporative cooling pad. However, in the aforementioned background technologies, there are no technical means to increase the cooling effect by separating the space between the cold air generation section and the hot air generation section, to improve cooling performance by increasing the cold air discharge volume and cold air discharge flow velocity, and to enable continuous supply of cold air without discharge resistance even during defrosting.
