Modern hybrid variable refrigerant flow heating and air conditioning systems are advanced two-pipe units that replace refrigerant and use water in the piping between indoor units and the hybrid branch circuit control. This cutting-edge design eliminates all need for costly continual leak detection efforts, servicing, and maintenance by removing refrigerant from the portion of the system.
This design offers numerous advantages and capabilities other, more traditional HVAC systems simply cannot match. These units are quick to install, easy to set up, and they are completely decentralized which allows for installation in phases. The presence of water, not refrigerant in its indoor units, these systems are capable of providing completely stable control of indoor temperature.
This integrated heating and air conditioning solution is an excellent choice for various applications, including mixed-use buildings, office areas, hotels, medical centers, hospitals, and education facilities. However, your customers will probably want to know more about the key features of these hybrid VRF systems.
What Are The Key Features Of VRF Systems?
Hybrid VRF systems are a revolution in commercial heating and cooling. The water-based technology between the branch box and indoor units provides a safer, more comfortable alternative to commercial HVAC. It’s excellent for buildings with many small occupied spaces because of its key features:
Simultaneous Cooling & Heating
Hybrid VRF systems are capable of providing simultaneous cooling and heating within different zones of the building. This allows for greater flexibility, comfort, and convenience in both residential and commercial applications. What’s more, these systems also have exceptional heat recovery capabilities that further enhance operational efficiency.
Speaking of efficiency, these units offer unparalleled energy efficiency, especially when simultaneous heating and cooling is required. This is possible due to their advanced heat recovery operations. In fact, the more simultaneous cooling and heating there is, the system will save more energy.
Water, Not Refrigerant In Indoor Units
The two-pipe recovery system incorporates water as the medium for heat exchange, not refrigerant. This combines the efficiency of advanced VRF systems with the comfort of the more traditional hydronic solutions. This combines the best of the two very different worlds into a single efficient solution.
Modularity & Flexibility
Hybrid VRF systems are extremely versatile, flexible, and modular due to their size and design. These systems have an extremely small footprint, which means they can fit into small spaces without problems. Additionally, their modular design allows you to install these systems in phases, which grants greater installation efficiency.
Lower Maintenance Costs And Better Safety
A hybrid VRF system features an architecture and design that minimizes the need for continual leak detection in confined spaces because it uses water, and not refrigerant, within the piping between the indoor units and branch boxes. What’s more, there’s no possibility of refrigerant escaping, which both minimizes maintenance costs and maximizes safety.
Less Equipment And Materials
These hybrid systems require far less materials and equipment for proper installation. First of all, they need far less piping when compared to standard chiller systems with 4 pipes. Also, they do not need actuators, sensors, valves, or external pumps for adequate operation.
Speaking of operation, hybrid VRF systems are extremely quiet. This stems from the fact that they implement water, not refrigerants. This, in turn, means that as water circulates through terminal fans, the system ensures extremely quiet operations, as well as completely silent operation off-cycle.
These types of HVAC systems delivered very mild off-coil temperatures. They are designed in such a way that they offer gradual temperature changes within the area that is air conditioned. This ensures a stable and comfortable environment.
