Rooftop Air Conditiong Units for US Warehouses

Rooftop unit is a large-scale equipment integrating cooling, heating, ventilation and air treatment functions. It is directly installed on the roof of the warehouse and is characterized by modular design, high efficiency and energy saving.

Warehouse Application Advantages and Scenario Adaptation

Installation and Space Utilization Advantages:

Independent installation on the roof: no need to take up warehouse floor space, saving about 3-5% of indoor area, suitable for high shelf warehouses (shelf height ≥ 10m);

Rapid Deployment: modular unit on-site splicing time of ≤ 2 days (traditional central air-conditioning requires 7-10 days), suitable for warehouse renovation projects;

Waterproof Integration: the base of the unit is equipped with its own water-stopping weir + flexible waterproof layer, integrated construction with the roof waterproofing system, eliminating water leakage. Waterproof integration: the base of the unit comes with a water-stop cofferdam + flexible waterproof layer, which is integrated with the roof waterproofing system to eliminate the risk of water leakage.

Installation specifications:

Load-bearing requirements: roof load-bearing ≥500kg/㎡, the base of the unit needs to be reinforced with 10# channel steel, and the spacing between the fixing bolts and the roof is ≤500mm;

Drainage design: the slope of the condensate tray is ≥3%, and the diameter of the drainage pipe is ≥DN32, and the U-type water seals are installed to prevent back-flooding;

Inspection channel: the roof needs to be reserved for the width of the inspection channel ≥1.2m, and the periphery of the unit is set up with guardrails (height ≥1.1m). The perimeter of the unit is equipped with guardrails (height ≥1.1m).

Case: an e-commerce logistics warehouse (10,000 square meters) using 4 sets of 120kW inverter rooftop machine, with CO₂ concentration sensor (threshold 1000ppm), on-demand adjustment of the fresh air volume, the average daily power consumption in summer compared with the traditional air conditioning is reduced by 12,000 kWh, with a payback period of 2.5 years.
