VRH modular heat pipe multi-unit composite air conditioning system
The VRH modular heat pipe multi-connected composite air conditioning system is one of the main products in Canatal fluoropump energy-saving technology roadmap, belonging to a new generation of high-efficiency and energy-saving multi-connected heat pipe host air conditioning products. The system adopts full inverter technology, fluoropump multi-connected technology, heat pipe technology, and AI intelligent control technology, which can achieve full inverter control, full utilization of outdoor natural cold sources, and efficient cooling of waterless data centers. The outdoor host of the system is modular, and the indoor terminals are diversified. The indoor side can use various forms of heat pipe terminals, such as heat pipe backplates, in-row heat pipes, in-room heat pipes, heat pipe fan walls, ceiling-mounted, and top-mounted air conditioners. The outdoor side can be combined with atomized spray evaporative condensation technology, which has advantages such as higher applicability, more reliable heat dissipation performance, lower water consumption, and extended utilization time of natural cold sources.

Technically advanced and reliable
The fully variable frequency compressor parallel design freely adjusts the compressor frequency according to the actual thermal load, supplying on demand to achieve energy saving; combined with fluoropump heat pipe technology, energy saving is achieved by fully utilizing natural cold sources when the temperature meets the preset value; the oil-free system has excellent low-load regulation performance, ultra-long pipeline operation, and small cooling capacity attenuation.
Adaptive multi-link, modular design
Independent mechanical refrigeration system and fluoropump natural cold system, stable and precise refrigeration; using plate heat exchanger, efficient heat transfer. The system host is modular in design, easy to assemble, expand and maintain. Using multi-link adaptive technology, both indoor and outdoor units can achieve multi-link application.
High efficiency and energy saving, low PUE
The system has three operating modes (compressor refrigeration mode, mixed refrigeration mode, natural cold source refrigeration mode). When the outdoor temperature is low, the natural cold source is used to replace or reduce the compressor operation, reducing the unit power consumption. The parallel compressor scheme can fully utilize the evaporator and condenser heat transfer area under partial load, improving the unit energy efficiency. Typical urban unit pPUE = 1.08~1.22.
Diversified terminal
Indoor terminal types are flexible and diverse, and can adopt backplane type, inter-row type, room-level type, ceiling type, top-mounted type, near-end wind wall type, etc., and can be flexibly selected according to the on-site needs. Diversified terminals are close to the heat source refrigeration, and the heat exchange effect is higher. The terminal supports single-pipe and double-pipe forms, and can be used alternately with the outdoor host.
