The unit is divided into two sections: the compression condensation section and the air handling section. The compression condensation section is assembled in a modular manner, while the air handling section features a modular design by function. The housing is constructed with a cold-bridge-free aluminum alloy frame and a polyurethane sandwich panel with double-sided steel plates. The unit's assembly methods are versatile and easy to install, suitable for placement on rooftops or outdoor open areas without the need for a dedicated machine room. The product is ideal for large industrial sites such as factories and workshops in areas with limited water access or water scarcity, and can also be used for full-air conditioning systems in comfort-oriented places like hospitals, malls, supermarkets, restaurants, and office buildings.
Roof-mounted Explosion-proof Air Conditioning Unit Product Features
1. Comprehensive Variety and Specifications: Roof-mounted 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 suitable for comfort air conditioning environments.
Products are available for custom production with cooling capacities ranging from 12kW to 490kW, catering to the needs of different high airflow and space air conditioning applications.
Products are categorized into series such as standard, purification, and 100% outdoor air types, with optional functional modules for easy implementation of various functions, including cooling, heating, dehumidification, humidification, air purification, noise reduction, and energy-saving fresh air.
2. No dedicated machine room required, saving investment: The frame of this series of units is treated with anti-corrosion and waterproofing, allowing the entire unit to be placed on the roof or outdoor space, eliminating the need for a machine room and saving on building space and construction investment costs: The unit is a full-air system, without a cooling water or chilled water system, thus saving on auxiliary equipment such as chilled water pumps, cooling water pumps, cooling towers, fan coils, and piping.
Investment-ready, reducing 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 modular, with customizable functional sections, simple configuration, and versatile options. The volume of each functional section
Small, lightweight, and customizable to fit on-site conditions, easy to transport and install. 4. Cold bridge-free frame, low air leakage rate: The air treatment sections use cold bridge-free aluminum alloy frames, 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.
With required corrosion and rust resistance, vibrant colors, and aesthetic appeal. 5.
