What are the differences between split and VRF systems?

For heating and cooling your home and office, you ought to choose an ideal HVAC solution. Presently, the VRF (variant refrigerant flow) and split HVAC system are the two most popular choices. These units are quite efficient and do not depend on the ductwork to maintain the temperatures. To decide which one between them is a better choice, you should consider factors like budget, the structure’s age, technology, and the size of the room. Considering these aspects before deciding will help you make the right choice. 

Which is better: VRF or split AC

Whether you should opt for the split or VRF system depends on your application. While the prior device is ductless and used more frequently in residential settings, the latter is more suitable for a commercial building with square footage. 

How does a VRF system work?

The VRF systems work to adjust the refrigerant flow according to each indoor evaporator. In the VRF units, every evaporator has its own set of controls that allows for air conditioning in the gym room, for example, and heating in the kid’s room to occur simultaneously. The indoor units are connected to the outdoor unit through control wires. And the outdoor units respond to the heating or cooling requirements of the system by controlling the compressor speed to match the needs.

Where should you use VRF systems?

Since the VRF systems can simultaneously heat and cool different rooms, they are ideal for facilities where different temperatures need to be maintained in different potions of the building. Or at places where individuals should be able to set their own comfort zone. A few commercial spaces where you should install VRF systems include apartment buildings, hospitals, data centres, dormitories, labs, restaurants, offices, hotels, large retail stores, or universities.

How much do the VRF units cost?

When installing the AC, you will find that the initial costs incurred would be more in the case of VRF systems than split units. It is so because of the technology and work involved. 

How does a split AC works?

A split AC is a conventional ductless HVAC system featuring two components, including a heat pump or air conditioner compressor. In these systems, the compressor is put up outdoors and is connected to the indoor components like the furnace or blower coil. The units are linked through copper tubing and cables. The system gets rid of the hot air or humidity by eliminating it via a compressor. To heat the space, it works in reverse and pulls out cold air while providing warm air.

How much do they cost?

One of the most efficient HVAC units, the split systems are affordable. They cost three times more than ducted AC units and are simpler to operate and easier to maintain.

Where should you install split systems?

Split systems are mounted on the walls and are suitable for a larger room because of their high cooling capacity. You can install them in small commercial business spaces, mid-sized commercial applications, newer construction, multi-family housing, and small apartments.

So, both the split and VRF systems are energy efficient and work great. However, before making a choice, you should consider factors like budget, application, and space to make the right decision.
