The unit is divided into two sections: the compression and condensation section, and the air handling section. The compression and condensation section is assembled in a modular manner, while the air handling section features a modular design divided by function. The casing is constructed with a cold bridge-free aluminum alloy frame and a polyurethane sandwich panel made of double-sided steel plates. The unit's combination methods are versatile and flexible, allowing for easy installation on rooftops or outdoor open spaces without the need for a dedicated machine room. The product is suitable for large industrial sites such as factories and workshops in areas with不便 access to water or limited water resources, as well as for full-air conditioning systems in comfort-oriented spaces like hospitals, shopping malls, supermarkets, restaurants, and office buildings.
Roof-mounted Explosion-Proof Air Conditioning Unit Product Features
1. Comprehensive Variety & Specifications: Rooftop air conditioning units are divided into three series based on function: Cold Air Type (L), Heat Pump Type (R), and Constant Temperature and Humidity Type (H). The Constant Temperature and Humidity Type is suitable for process air conditioning environments with high requirements for temperature and humidity, while the Cold Air Type and Heat Pump Type are ideal for comfort air conditioning spaces.
Products are available for customization in cooling capacities ranging from 12kW to 490kW, catering to requirements for different high air volume and space-specific air conditioning applications.
Products are categorized into series such as standard, purification, and 100% fresh air types, which are available with a range of optional function modules for easy realization of cooling, heating, dehumidification, humidification, air purification, noise reduction, and energy-saving fresh air functions.
2. No dedicated machine room required, save on investment: The series of units are treated with anti-corrosion and waterproofing, allowing the entire unit to be placed on the roof or outdoor space without a machine room, saving on building space and construction investment costs: The units are a full-air system with no cooling water or chilled water systems, which saves on accessories such as chilled water pumps, cooling water pumps, cooling towers, fan coils, and piping.
Investment readiness has reduced the construction cost. 3. Convenient transportation and easy installation: The unit design features two structural types: Standard and Purification. Standard units with cooling capacities below 140kW are designed as an integrated structure, while those above 140kW are split structures, facilitating transportation and installation. Purification units are modularly designed, with configurable functional sections as needed, offering simple configuration and flexibility. The volume of each functional section
Compact, lightweight, and customizable according to on-site conditions; easy to transport and install. 4. Cold bridge-free frame, low air leakage rate: The air treatment sections use a cold bridge-free aluminum alloy frame, with panels made of polyurethane high-pressure foam insulated boards (outer panel: electrostatically coated steel plate, inner panel: galvanized steel plate). The frame and panels are equipped with special sealing insulating strips and a unique outdoor rainproof structure design, ensuring the unit's outdoor operation is secure and efficient.
With required corrosion and rust resistance, vibrant colors, and a stylish appearance. 5. The unit employs a renowned fully enclosed scroll compressor, ensuring smooth operation, reliable performance, and high refrigeration efficiency: Customized units with heat recovery for energy-saving and environmental protection can also be provided upon customer request.
