There are so many different types of HVAC systems, understanding how each one connects and interacts with Home BMS can be a real challenge. This topic is to simplify and clarify how home BMS interacts with the VRF system.
VRF HVAC System:
VRF, or Variable Refrigerant Flow system, is an advanced HVAC system used for larger residential, commercial, homes and offices. VRF system design is that it has a single outdoor unit connected to multiple indoor units through refrigerant pipes. This design enables complete flexibility and customizability control for each individual indoor unit.
VRF System Integrated With Building Management System “BMS”:
While connecting BMS with the VRF system they come out as closed systems. This means that they are only able to communicate internally, and commands can only be sent and received through the VRF manufacturer’s native control functionality. As a result, these systems are unable to communicate externally without the use of an additional device. This challenge creates a significant hurdle for integrating VRF HVAC systems into a building management system. Presently, the most common way to overcome this challenge is through a BAC-net interface.
VRF and building management systems, require a device that can act as an intermediary to translate commands and requests between the two simply and seamlessly.
This is where Cool-Master Net comes in. Since Cool Automation works directly with both BMS and VRF manufacturers, Cool Master Net is able to provide native-like integration for any VRF system with almost any BMS main controller. Additionally, since Cool-Master Net’s function is to provide external access to the VRF system, it is also an essential tool in order to provide access to the BMS cloud-based remote control application. Cool-Master Net’s advanced technologies are able to read the specific internal address assigned by the VRF system for each indoor unit. Cool Master Net will then automatically identify those units through the Home Automation System, and provide the integrator with quick and easy access to each individual unit through the main controller. This functionality provides simple and intuitive management for the entire system both locally as well as remotely. Simply, Cool Master Net is an all-in-one solution for VRF and BMS integration. It is simple to install, easy to configure, and operates within the system, while remaining unseen in the background.
