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 outer shell is constructed with an aluminum alloy frame that prevents cold bridging 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 comfort applications such as hospitals, shopping malls, supermarkets, restaurants, and office buildings with full air conditioning systems.

Roof-type Explosion-proof Air Conditioning Unit Product Features

1. Comprehensive variety and specifications: Roof-mounted air conditioning units are categorized into three series by 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 applications.

Products are available for customization with cooling capacities ranging from 12kW to 490kW, catering to various high airflow and different space air conditioning requirements.

Products are categorized into series such as standard, purification, and 100% outside air types, with various functional sections available for selection, facilitating a range of features including 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 civil engineering 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 readiness 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, which facilitates transportation and installation. The Purification unit is modularly designed, with configurable functional sections as needed, offering simple and versatile configurations. 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 insulation 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 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 conservation and environmental protection.
