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 assembly methods are versatile and convenient, allowing for installation on rooftops or outdoor open spaces without the need for a dedicated machine room. The product is suitable for large industrial spaces 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 places like hospitals, shopping malls, supermarkets, restaurants, and office buildings.
Roof-mounted Explosion-proof Air Conditioning Unit Product Features
1. Comprehensive Variety and Specifications: Rooftop air conditioning units are categorized into three series based on function: Cold Air Type (L), Heat Pump Type (R), and恒温恒湿型(H). The恒温恒湿型(H) is suitable for process air conditioning environments with high requirements for temperature and humidity, while the Cold Air Type (L) and Heat Pump Type (R) are ideal for comfort air conditioning spaces.
Products are available for customization with cooling capacities ranging from 12kW to 490kW, catering to requirements for different high airflow and various space air conditioning applications.
Products are categorized into standard, purification, and fresh air types, among others, based on applicable usage locations. Various functional sections are available for selection, facilitating multiple functions such as cooling, heating, dehumidification, humidification, air purification, noise reduction, and energy-efficient fresh air.
2. No dedicated machine room required, cost-saving: The series of units have been treated with anti-corrosion and rainproof measures, allowing the entire unit to be placed on the roof or outdoor space, eliminating the need for a machine room, saving building space, and reducing civil engineering investment costs: The units are all-air systems, without cooling water or chilled water systems, thereby saving on chilled water pumps, cooling water pumps, cooling towers, fan coils, and pipeline accessories.
Investment preparation has reduced the construction cost. 3. Convenient transportation and easy installation: The unit design features two structural types: Standard and Purification. The Standard unit, with a cooling capacity below 140kW, is designed as an integrated structure, while above 140kW, it is a split structure, facilitating transportation and installation. The Purification unit is modularly designed, allowing for the configuration of various functional sections as needed, with simple and flexible options. 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 handling sections use cold bridge-free aluminum alloy frames, with panels made of polyurethane high-pressure foam insulated sandwich panels (outer panel: electrostatically sprayed steel plate, inner panel: galvanized steel plate). The frame and panels are equipped with special sealing and insulation strips, as well as a unique outdoor rainproof structure design, ensuring the unit operates reliably outdoors.
With required corrosion and rust resistance, vibrant colors, and attractive appearance. 5. The unit is equipped with a brand-name fully enclosed scroll compressor, offering smooth operation, reliable performance, and high refrigeration efficiency. According to customer requirements, non-standard heat recovery units can also be provided for energy saving and environmental protection.
