As the world becomes increasingly fast-paced, technology continues to advance rapidly, making it easier to accomplish numerous tasks quickly. One area that has not been left behind is the HVAC (heating, ventilation, and air conditioning) system, where the VRV (variable refrigerant flow) system is taking the lead.
Developed by Daikin in 1982, this large-scale HVAC system is ductless and performs at a high capacity, standing out for its unique approach to handling air.
Unlike conventional HVAC units that blend outside air and return air, cool it in a handler, and force the cooled air through a duct system for distribution throughout a structure, the VRV system works differently. It allows multiple indoor units to run on the same system, making better use of variable refrigerant temperature (VRT) and return air. It sends refrigerant throughout the building to indoor coil systems, and returns it to a compressor to be repressurized and releases heat through the condenser.
Some of the most notable benefits of the VRV system are:
Energy Efficiency: VRV systems are highly energy efficient as they use inverter technology to adjust the compressor speed to match the actual cooling or heating requirements of the building.
Easy to Install: VRV systems require less ductwork and wiring, which results in reduced installation costs, especially when compared to traditional HVAC systems.
Quiet Operation: The VRV system operates quietly due to its low sound level, making it ideal for residential and commercial buildings.
Sleek and compact: Compared to traditional equipment, VRV units are much less bulky, making them an excellent solution for retrofitting, renovating or outfitting areas with limited space.
Customizable temperature settings: If the right VRV system for the building is selected, occupants can heat and cool different zones at the same time, allowing workers and sensitive equipment to stay safe.
Low Maintenance: VRV systems require minimal maintenance as they have fewer mechanical components compared to traditional HVAC systems.
High Control: The VRV system allows for greater control over the indoor environment and can be easily integrated with building automation systems.
Eco-friendly: VRV systems use eco-friendly refrigerants, which have a low Global Warming Potential (GWP) and Ozone Depleting Potential (ODP), making them environmentally friendly.
At Etiwa Tech, we are at the forefront of technological advancements, and in partnership with Daikin, we have established the Daikin Development Centre, the first of its kind in Africa. It offers discounted HVAC training courses designed to provide the knowledge and skills needed to confidently and accurately operate a VRV system.
Overall, the VRV system is a highly efficient and cost-effective option for buildings that require individual temperature control and high performance regeneration response.
