Variable Refrigerant Flow Systems for Your HVAC
The Variable Refrigerant Flow (VRF) system for heating, ventilation, and air conditioning (HVAC) is the latest in innovative and technologically-intelligent systems, utilizing an on-board communication system to self-regulate. A VRF system can be used for both air conditioning and heating, depending on the needs of your home or office. Its multi-zone technology allows for specified cooling of different areas of your space, for efficient power and energy utilization. There are three main options for VRF systems that you can choose from: cooling only, heating and cooling (not simultaneously), and the most complex— heating and cooling that can run at the same time in different zones.
As advancements are made in HVAC systems, our Wake Forest HVAC professionals at Mechanical HVAC Services stay up to date on installation training, system analytics, and available upgrades, so that we can provide the best in HVAC service and product options. We know that automated systems and remote operation is just the beginning in HVAC technology.
What Makes a VRF System Different from Traditional Systems?
There are several equipment differences that set VRF apart, but the biggest difference is that there is no chilled water apparatus. The VRF system runs solely on refrigerant as the coolant material for the entire system.
The typical components for a VRF system include:
- a singular outdoor unit, that contains the compressor or several compressors
- multiple indoor units(zones) that communicate with the outdoor component to determine power load and energy required
- communication wiring
- refrigerant piping
- a centralized controller
- control panels as needed for different zones
- wireless remote control
The system works by maintaining an “off” mode until an indoor control is activated, at which time the outdoor unit analyzes the outdoor temperature as compared to the desired indoor temperature indicated by the zone, to asses and apply the exact compressor energy level required to achieve the indoor requirements. If another zone is activated, the compressor unit recalculates and adjusts. This all works automatically and can be set according to the desired modes (set temperature, constant cool/heat, fan speed.)
How Can VRF Benefit Your Home or Office?
The benefits of a VRF system consist of savings—both in energy and money. The technology within the system and its ability to communicate allow is to reduce or increase power consumption as you manipulate the system from indoors. It utilizes the outdoor ambient temperature to self-regulate, making it much more efficient than traditional water-cooled systems. The efficiency of the VRF system, when compared to traditional HVAC systems, can equate to up to a 50% energy savings. Not only will you notice the savings on your energy bill, but you will also notice the quiet operation, consistent comfort, and reduction in repairs and service calls.
For a new building installation, or to replace your old system, the VRF option is perfect for tight spaces because of the reduced size of piping and ducts required. These systems are ideal for historical renovations as well, because the installation of refrigerant piping is much less invasive than hot and chilled water piping and subsequent duct work. The multi-zone technology of VRF HVAC systems is the ultimate cost-effective choice for areas that have variable operating modes, such as high-rise buildings or ones where different occupants will require different settings. It also has the ability for expansion, so you can adjust and add to the system components for larger or smaller spaces.
