Airport air conditioning Unitary AC

floor-mountedair condenser

Overview
Shenling Unitary Air Conditioners provide targeted, efficient climate control for airport facilities. Designed for localized cooling and environmental control in areas such as lounges, server rooms and operational zones, these floor-standing air-cooled units complement larger central systems by offering cost-effective conditioning where precise control is required.

Key features of the Shenling Unitary Air Conditioners

• 1. Wide Application Range
• Broad capacity options to meet varied airport zone requirements.
• Air-cooled floor-standing type: 4HP to 100HP
• Water-cooled floor-standing type: 12HP to 88HP
• Air-cooled duct type: 4HP to 40HP
• Two condensing options:
• Water-cooled units: use a cooling tower for heat exchange.
• Air-cooled units: paired with a direct expansion outdoor unit.
• Wide operating temperature range:
• Standard units — Cooling: 18°C ~ 43°C (cooling only & heat pump)
• Standard units — Heating: -7°C ~ 21°C (heat pump)
• Thermostatic & humidistatic: -20°C ~ 43°C
• Customized units — Cooling only / Thermostatic & humidistatic: -30°C ~ 52°C
• 2. High Reliability
• High-quality components from established suppliers to ensure efficient, reliable operation.
• PLC control (optional): built-in PCB with optional customizable PLC for industry-specific integration.
• Backup function: compressor backup mode for emergency standby.
• Automatic compressor rotation to balance runtime and extend component life.
• Standby function supports up to 16 units for automatic rotation or switchover on failure.
• Low air leakage and excellent thermal insulation: streamlined steel frame, sound-absorbing and heat-insulating materials, double-skin cabinet with color-coated outer shell and galvanized inner lining, high-pressure polyurethane insulation.
• Auto restart: unit restores previous state after power return.
• Unit protection: phase sequence, high/low pressure, compressor overload, overheating, start/stop delay, fan thermal and motor overload protections.
• Intelligent defrost: heat pump units include intelligent defrost to improve efficiency.
• Thermostatic and humidistatic control: electrode or wet-film humidifier with temperature control 18–28°C (±0.8°C) and humidity control 50%–70% (±5%–8%).
