Marine Steel Box Girder Tunnel Local Cooling Air Conditioner (Cooler)

The Marine Steel Box Girder Tunnel Local Cooling Air Conditioner (Cooler) is specifically designed for ventilation and air exchange in high-temperature work environments such as hull painting, docks, shipways, segments, and tunnel sections, improving the working conditions. It is a system that cools specific locations, areas, or workstations without requiring specialized connections. Outdoor air is cooled by the unit, delivering suitable temperatures and fresh air precisely and conveniently to the required workstations and areas.

Detailed Introduction

Features and functions of the Marine Steel Box Girder Tunnel Local Cooling Air Conditioner (Cooler):

1. The unit consists of a compressor, condenser, evaporator, cooling fan, supply fan, and coarse filter. The supply fan is a medium-pressure, high-efficiency backward-curved fan with high airflow and pressure, featuring moisture resistance, low-temperature tolerance, low noise, stable and reliable operation, and strong cooling capacity. It is widely used for rapid cooling of mechanical components, chemical materials, finished products, food, medicinal materials, and coating raw material crushing.

2. The unit system is optimized for design, ensuring a high energy efficiency ratio.

3. With advanced design, it offers low energy consumption, long air supply distance, short defrosting time, and excellent cooling performance compared to similar products.

4. The unit uses an optional micro-differential pressure controller to intelligently control defrosting frequency, ensuring "defrost only when needed," which reduces temperature fluctuations and saves energy compared to conventional timed defrosting methods.

5. The unit employs anti-oxidation gas protection welding technology, ensuring high internal cleanliness. The evaporator and copper tubes are arranged in an innovative way to reduce air-side resistance, minimize contact thermal resistance, and enhance heat transfer efficiency.

6. This unit can maintain constant low temperatures in spaces, ensuring comfort for welders and stable welding processes within specific temperature ranges. Such equipment is widely used in enclosed large welding spaces like bridges, shipyards, and tunnel boring machines.

Selection method for the Marine Steel Box Girder Tunnel Local Cooling Air Conditioner (Cooler):

1. Unlike other brands of air conditioners (coolers) on the market, this unit is equipped with a refrigeration compressor. Selection is based on airflow, air pressure, and control temperature requirements. It is a low-temperature cooling device, with conventional models controlling temperatures between 0-20°C (±3-5°C accuracy), and ultra-low-temperature models capable of reaching -20°C.

2. When selecting this unit, please determine whether it is for cooling components, finished products, raw materials, localized areas, or entire spaces.

3. If airflow cannot be provided during selection, please specify the weight and quantity of items to be cooled, the working environment, temperature difference, and cooling time required.

The Marine Air Conditioner (Cooler) is a portable cooling device designed by our company to meet the current needs of the shipbuilding industry and its working conditions. This product is primarily used in harsh, high-temperature environments such as ship segments, sandblasting, deck operations, bridge assembly welding, and tunnel boring machine operations.
