How VRF HVAC integrates with Home Automation

There are so many different types of HVAC (Heating, Ventilation, and Air Conditioning) systems, understanding how each one connects and interacts with Home Automation systems can be a real challenge.

The goal of this article is to simplify and clarify how home automation interacts with VRF HVAC systems.

What is a VRF HVAC system?

A VRF, or Variable Refrigerant Flow system, is an advanced type of HVAC used for larger residential and commercial, homes and offices. The unique aspect of a VRF system’s design is that it has a single outdoor unit connected to multiple indoor units through coolant piping and communication wiring in place of conventional ducting. This design enables complete flexibility and customizability regarding climate control for each individual indoor unit.

This design, in theory, should be ideal for both local and remote climate control, management, and automation, but naturally, it isn’t that simple.

Can VRF systems be integrated into Home Automation?

The problem encountered when attempting to automate a VRF system is that when they are first purchased, they come out-of-the-box 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 Home Automation system. Presently, the most common means of overcoming this challenge is through a BACnet interface , which makes the automation process incredibly clunky and complicated with multiple points of potential failure.

To make matters worse, Home Automation and VRF systems use completely different languages to communicate, and therefore have no native means of understanding requests, commands, or information that need to be sent between the two systems.

The VRF and Home Automation systems, therefore, require a device that can act as an intermediary in order to translate commands and requests between the two in a simple and seamless way.

How VRF HVAC Integrates with Home Automation Systems

This is where CoolMasterNet comes in. Since CoolAutomation works directly with both Home Automation and VRF manufacturers, CoolMasterNet is able to provide nativelike integration for any VRF system with almost any Home Automation main console. Additionally, since CoolMasterNet’s function is to provide external access to the VRF system, it is also an essential tool in order to provide access for the Home Automator’s cloud-based remote control application.

 

Functionally, CoolMasterNet’s advanced technologies are able to read the specific internal address assigned by the VRF system for each indoor unit. CoolMasterNet will then automatically identify those units though 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 put, CoolMasterNet is an all-in-one solution for VRF and Home Automation integration. It is simple to install, easy to configure, and operates flawlessly within the system, while remaining unseen in the background.
