Modular Air-Cooled Chilled (Hot) Water Units are integrated central air-conditioning equipment that use air as the cold (heat) source and water as the cooling (heating) medium. They serve as dual-purpose cold and heat sources to meet the needs of air-conditioning and heating throughout the year.
Installed on rooftops, ground levels, podium decks, and other open-air locations, these units eliminate the need for boiler rooms and dedicated machine rooms, thereby reducing investment in civil engineering projects. Moreover, modular air-cooled chilled (hot) water units do not require cooling towers, cooling water pumps, or cooling water systems, which saves on investment and operational costs for cooling water systems.
Their operation is fully controlled by microcomputers, facilitating easy installation, management, and maintenance.
These units are widely used in comfortable central air-conditioning systems for public facilities such as hotels, shopping malls, office buildings, exhibition halls, airports, and stadiums. They also meet the diverse operational requirements of process air-conditioning systems in industries such as electronics, pharmaceuticals, biotechnology, textiles, chemicals, metallurgy, electricity, and machinery.
Features of Modular Air-Cooled Units:
Versatile Forms and Broad Application Range: Available in standard units, heat recovery units, new refrigerant R410A units, and low-temperature forced-air units, they cater to the needs of various occasions.
Modular Design: Provides high flexibility in combination, facilitating energy regulation and easy capacity expansion. Transportation, installation, commissioning, and maintenance are straightforward.
Space-Saving: With compact structures, small footprints, and light weights, these units can be directly installed on rooftops or in outdoor spaces without dedicated machine rooms, saving building space.
Elegant and Beautiful Appearance: The unit casings are made of high-quality stainless steel plates or cold-rolled steel plates with coating, featuring clean colors, beautiful aesthetics, and strong corrosion and rust resistance. The unit structure is designed based on actual engineering needs, combining simplicity, practicality, and elegance.
Reliable Operation and Stable Performance: The compressors, fans, refrigeration system components, computers, and electrical control components of the units are all high-quality and reliable. The products are the first to pass national mandatory CRAA certification and quality safety certification. Each unit undergoes rigorous testing and inspection by national-level performance testing centers before leaving the factory.
Comprehensive Protection: The units are equipped with temperature protection switches, overload relays, high and low-pressure safety switches, phase reversal and under-phase protection, antifreeze switches, and delayed start-up protection devices to ensure safe and reliable operation of the main unit.
Fully Automatic Intelligent Control: Using high-quality microcomputer control with full Chinese display, the operation interface is simple and user-friendly. With high automation and comprehensive functions, it can manage unit startup and shutdown procedures, timing control, pump management, intelligent defrosting, intelligent antifreeze, full-function fault alarms, and self-diagnosis. Equipped with RS485/RS232 communication interfaces, it facilitates centralized and remote monitoring of the units by users.
Convenient User Operation and Maintenance: The refrigerant is already charged when the unit leaves the factory, and all protection parameters are set. Testing and debugging are completed according to national standards. Field installation only requires connecting the power supply and water supply pipes, and operation only requires operating the computer controller. The compressor, refrigeration components, and electrical control system of the unit are placed at the bottom of the unit and isolated from the air system, providing users with a good operating and maintenance environment.
