Outdoors unit of VRF-systems are core elements of structure, and include compressors, fan, evaporators, valve system, advanced electronic control system, based on latest technology and research of producers. At usually, outdoors units devide by compressor type (DC-inverter or Digital Scroll), Horizontal or vertical air-exhaust arrow, air- or water- cooled, for 2-pipe or 3-pipe refrigeration system, etc.
DX-system (direct evaporator systems)
Range of indoor units multizone systems in its diversity are not inferior to domestic and semi-industrial series and allow us to solve all complex processing tasks of air in rooms and buildings of any type conveniently fitting into their interior.
To manage VRF systems, we offer a wide range of wired controllers that diversion can be divided into three main groups: the control for indoor units - you can also divide them into individual (for one unit) and group (for multiple units), for monitoring operating parameters outdoor units, for especially focused tasks - specialized controllers. If necessary, on the basis of controllers can build a more developed and complex control system with data output on a server BMS, Internet, dedicated management server.
As accessories for the VRF systems are changed refrigerant pipes connectors (refnets) joint refnets for modular outdoor units, power meters with digital output for system consumption energy registration.
For indoor units options may also be considered drainage pumps.
The software is divided into control software and software for the calculation and design systems. Separately presented diagnostic software for specialists in service and repair.
