Roof-mounted explosion-proof air conditioning units are all-air systems designed for indoor air treatment, integrating cooling, heating, dehumidification, humidification, ventilation, and air purification functions into medium to large-sized air conditioning equipment. This product combines modular air handling units with direct expansion air conditioning technology, enabling centralized comprehensive control of cooling and air conditioning. It features high efficiency and energy saving, simple system, stable performance, compact structure, high control accuracy, safety and reliability, low noise, high static pressure, minimal vibration, high corrosion resistance, good sealing, excellent rain and dust protection, easy installation, and attractive appearance. The microcomputer control ensures the product's performance and quality are fully demonstrated and utilized.

The unit is divided into two parts: the compression and condensation section, and the air treatment section. The compression and condensation section is assembled in a modular manner, while the air treatment section features a modular design divided by function. The housing 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 sites like factories and workshops with limited water access or in water-scarce areas, as well as for full air conditioning systems in comfort-oriented places such as hospitals, shopping 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 ideal for comfort air conditioning spaces.

Products are available for custom production with cooling capacities ranging from 12kW to 490kW, catering to different high airflow and space-specific air conditioning needs.

Products are categorized into standard, purification, and all-new air series according to applicable usage locations, and various functional sections can be optionally added for convenient implementation of multiple functions such as cooling, heating, dehumidification, humidification, air purification, noise reduction, and energy-efficient 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, saving building space, and reducing construction investment costs: The unit is a full-air system, without a cooling water or chilled water system, thereby saving on chilled water pumps, cooling water pumps, cooling towers, fan coils, and piping accessories.

Investment readiness, reduced construction costs. 3. Convenient transportation and easy installation: The unit design features two structural types: Standard and Purification: Standard units with cooling capacities under 140kW are designed as an integrated structure, while those above 140kW are split structures for easier transportation and installation. Purification units are modularly designed, with configurable functional sections for simple and versatile setup. The volume of each functional section

Small, 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 cold bridge-free aluminum alloy frames, with panels made of polyurethane high-pressure foam insulated boards (the outer panel is electrostatically coated steel plate, and the inner panel is galvanized steel plate). The frame and panels are equipped with special sealing insulation strips and a unique outdoor-type waterproof structure design, ensuring the unit operates reliably outdoors.

With required corrosion and rust prevention, vibrant colors, and elegant appearance. 5. Equipped with a renowned fully enclosed screw compressor, the unit operates smoothly, offers reliable performance, and has high refrigeration efficiency: Customized heat recovery units can also be provided upon customer request, ensuring energy saving and environmental protection.

6. Equipped with a direct-drive low-noise axial fan and a rear-tilt centrifugal blowing fan, effective vibration isolation measures are implemented to ensure smooth and reliable operation of the unit with low noise and minimal vibration.

7. Various refrigeration components and control devices are of international brands, with high system reliability and stable performance.

8. Both evaporators and condensers are copper-tube-aluminum-finned heat exchangers, designed and optimized by computer and manufactured on a dedicated heat exchanger production line, ensuring high efficiency and energy savings.

9. Standard units are equipped with intelligent instrument control, allowing for the optional addition of industrial-grade programmable logic controllers (PLCs) according to customer requirements. Standard purification units come with industrial-grade PLC control, operating on optimized programs. They also feature self-diagnosis and fault alarm functions. The controllers are equipped with standard RS485 communication interfaces, enabling convenient remote control from a distance or connection to intelligent control systems, ensuring optimal equipment operation and reduced operating costs.

10. The return air of the unit can be in various forms such as horizontal air supply, side air supply on both sides of the unit, upward air supply, and downward air supply, making it particularly suitable for the transformation of air conditioning systems in old buildings (simply reroute the existing return air ducts to connect with the main unit on the roof): Additionally, replacing the main unit that has reached its service life is also very convenient, eliminating any concerns for the user.

11. The unit can be treated for explosion-proof and corrosion resistance according to specific requirements of the application. It is widely used in industries such as oil, chemical, and metallurgy. The explosion-proof marking for the unit is ExdbebibmbllBT4Gb, and there are also products with the explosion-proof marking ExdbebibmbllcT4Gb.
