Large-scale Hotel Heating And Cooling Dual-purpose Commercial Heating Cycle Purification Direct Expansion Air Conditioning Unit

This commercial direct expansion (DX) air conditioning unit is a large-scale dual-purpose cooling and heating HVAC solution built for factories, large hotels and commercial buildings. Integrating refrigeration, heating, air circulation and multi-stage air purification functions, it adopts high-efficiency direct expansion heat exchange technology to deliver stable and uniform temperature control while filtering dust, particulate matter and odors from circulating air. With a modular structure that supports full customization of capacity, air volume, configuration and functions, it meets the diversified HVAC demands of different large-space scenarios. Featuring high energy efficiency, reliable operation and intelligent control, it serves as a cost-effective comprehensive air conditioning solution widely used in hotels, factories, shopping malls and public buildings.

Large Hotels & Commercial Complexes: Suitable for guest rooms, lobbies, banquet halls and conference centers of large hotels, providing constant temperature control and air purification to ensure a comfortable and healthy indoor environment for guests.

Industrial Factories & Production Workshops: Ideal for large production workshops, assembly plants and industrial facilities, delivering large-air-volume cooling and heating circulation to improve the working environment and meet the temperature requirements of production processes.

Large Supermarkets & Shopping Malls: Perfect for shopping malls, hypermarkets and commercial pedestrian streets, with uniform air supply and strong load capacity to maintain a comfortable temperature in crowded and high-traffic commercial spaces.

Office Buildings & Business Parks: Effective for high-rise office buildings and industrial parks, supporting zoned control and flexible operation to meet the different temperature needs of different office areas while reducing comprehensive energy consumption.

Hospitals & Public Buildings: Applicable to hospitals, schools, libraries and other public buildings, with multi-stage air purification function to improve indoor air quality and meet the health and comfort needs of public places.

Exhibition Halls & Transportation Hubs: Suitable for large exhibition halls, railway stations, airport terminals and other tall and spacious places, with long air throw distance and wide coverage to achieve uniform temperature control in large spaces.

High Efficiency: Adopts high-efficiency scroll compressor and direct expansion heat exchange system with excellent heat exchange efficiency. The cooling and heating dual-purpose design meets year-round temperature regulation demands, and the large-air-volume circulating air supply system achieves uniform temperature control in large spaces with fast cooling and heating response.

Automatic Restart Function: Built-in power-off memory module and automatic recovery program. When power supply is restored after an outage, the unit automatically restarts and operates according to the previously set temperature, air volume and operation mode, perfectly adapting to unattended commercial and industrial scenarios.

Electronic Control System: Equipped with industrial-grade PLC electronic control system and high-definition touch operation panel, supporting multi-zone independent temperature control, timed start-stop, fault self-diagnosis and operation data recording. Optional IoT module realizes remote monitoring, centralized group control and energy consumption management.

Modular Design: The unit adopts a standardized modular structure. The compression module, heat exchange module, air supply module and purification module can be freely combined and customized. It is convenient for segmented transportation, on-site assembly and later component replacement and maintenance.

Advanced Cooling & Heating Technology: Adopts direct expansion cycle heat exchange technology with accurate temperature control and low cold/heat loss. The built-in multi-stage air purification system synchronously filters dust, odor and particulate matter during air circulation, realizing the integration of temperature regulation and air quality improvement.

High Airflow Efficiency: Large-air-volume centrifugal fan with optimized air duct design delivers long air throw distance and wide coverage, achieving uniform temperature distribution in large spaces without dead corners. The circulating air supply mode ensures full convection of indoor air and fast temperature rise and fall speed.

Energy Efficiency: High-efficiency compressor matched with direct expansion heat exchange technology achieves a high energy efficiency ratio, and the zoned control function avoids invalid energy consumption. Compared with traditional central air conditioning systems, it effectively reduces comprehensive operating energy consumption and saves long-term operation costs.

Durable Design: The unit shell is made of anti-corrosion galvanized steel sheet, and core components such as compressor and fan are selected from industrial-grade brands. It has stable performance, strong load capacity and long service life, suitable for long-term continuous operation in commercial and industrial environments.

Rapid Installation: Modular prefabricated design, the unit is pre-assembled and tested before delivery. On-site only requires duct connection and power commissioning, which greatly shortens the installation and construction period and reduces the impact on normal operation of the project.

Low Maintenance Requirements: Reasonable structural design with convenient access for overhaul, and modular components are easy to replace. The intelligent fault self-diagnosis system can quickly locate abnormal points, and daily maintenance only requires regular filter replacement and routine inspection, with low later operation and maintenance costs.

Versatile Compatibility: Supports full customization of cooling capacity, air volume, purification grade and installation method to adapt to different building structures and usage scenarios. It is widely compatible with various duct systems and building intelligence systems, suitable for both new construction and HVAC renovation projects in hotels, factories, commerce and other fields.
