Roof-mounted explosion-proof air conditioning units are complete air systems designed for indoor air treatment. They integrate functions such as cooling, heating, dehumidification, humidification, ventilation, and air purification into medium to large-scale 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 resistance, easy installation, and attractive appearance. The microcomputer control ensures that the product's performance and quality are fully realized and showcased.

The unit is divided into two parts: 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 by function. The outer shell is constructed with an aluminum alloy frame that prevents cold bridging and a polyurethane sandwich panel with double-sided steel plates. The combination methods of the unit are versatile and easy to install, allowing placement on rooftops or outdoor open spaces without the need for a dedicated machine room. The product is suitable for large industrial facilities such as factories and workshops in areas with不便 access to water or water scarcity, as well as for full air conditioning systems in comfort-oriented locations like hospitals, shopping malls, supermarkets, restaurants, and office buildings.

Roof Type 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Type (H). The恒温恒湿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 with cooling capacities ranging from 12kW to 490kW, catering to different high airflow and space cooling needs.

Products are categorized into standard, purification, and all-new air series based on applicable usage locations, and various functional sections are available for selection, facilitating a range of functions including cooling, heating, dehumidification, humidification, air purification, noise reduction, and energy-saving fresh air.

2. No dedicated machine room required, cost-saving: The series of units have been treated for corrosion and rain resistance, 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 units are all-air systems, without cooling water or chilled water systems, thereby saving on auxiliary equipment such as chilled water pumps, cooling water pumps, cooling towers, fan coils, and piping.

Investment preparation has reduced the construction cost. 3. Convenient transportation and easy installation: The unit design features two structural forms: standard and purification types. The standard type units with cooling capacity below 140kW are designed as an integral structure, while those above 140kW are designed as split structures for easier transportation and installation. The purification type units are modularly designed, with configurable functional sections as needed, offering simple configuration and flexibility. 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 sprayed steel plate, inner panel: galvanized steel plate). The frame and panels are equipped with special sealing and insulating strips, as well as a unique outdoor rainproof structure design, ensuring the unit operates outdoors effectively.

With required corrosion and rust resistance, vibrant colors, and elegant appearance. 5. The unit employs a renowned fully enclosed scroll compressor, ensuring smooth operation, reliable performance, and high refrigeration efficiency: Upon customer request, non-standard heat recovery units can also be provided for energy-saving and environmental protection.

6. Equipped with a direct-drive low-noise axial fan and a rear-tilted centrifugal blower, along with effective vibration isolation measures, ensuring the unit operates smoothly and reliably with low noise and minimal vibration.

7. A variety of refrigeration accessories and control components are for international brands, featuring high system reliability and stable performance.

8. Both the evaporator and condenser are copper tube-aluminum fin heat exchangers, optimized by computer design and manufactured on a dedicated heat exchanger production line, offering high efficiency and energy saving.

9. Standard units feature intelligent instrument control and can be optionally equipped with industrial-grade programmable logic controllers (PLC) according to customer requirements. Standard configurations of purification units come with industrial-grade PLC control, operating on optimized programs. They also include fault self-diagnosis and alarm functions. The controller is equipped with a standard RS485 communication interface, allowing for convenient remote control from a different location or connection to an intelligent control system, ensuring optimal equipment operation efficiency and reduced operation costs.

10. The unit's return air can be in various types, such as horizontal air distribution, side air distribution on both sides of the unit, upward air distribution, and downward air distribution, making it particularly suitable for改造old building's air conditioning systems (simply lead the original return air pipes to the roof for connection to the main unit): Additionally, replacing the main unit that has reached its service life is also very convenient, eliminating any concerns for the users.

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