By operating at varying speeds, VRF units work only at the needed rate allowing for substantial energy savings at load conditions. Heat recovery VRF technology allows individual indoor units to heat or cool as required, while the compressor load benefits from the internal heat recovery. Energy savings of up to 55% are predicted over comparable unitary equipment. This also results in greater control of the building’s interior temperature by the building’s occupants.
VRFs come in two system formats, two pipe and three pipe systems. In a heat pump two pipe system all of the zones must either be all in cooling or all in heating. Heat Recovery (HR) systems have the ability to simultaneously heat certain zones while cooling others; this is usually done through a three pipe design, with the exception of Mitsubishi and Carrier, whose systems are able to do this with a two pipe system using a branch circuit (BC) controller to the individual indoor evaporator zones. In this case the heat extracted from zones requiring cooling is put to use in the zones requiring heating. This is made possible because the heating unit is functioning as a condenser, providing sub-cooled liquid back into the line that is being used for cooling. While the heat recovery system has a greater initial cost, it allows for better zoned thermal control of a building and overall greater efficiencies. In heat recovery VRF systems, some of the indoor units may be in cooling mode while others are in heating mode, reducing energy consumption. If the coefficient of performance in cooling mode of a system is 3, and the coefficient of performance in heating mode is 4, then heat recovery performance can reach more than 7. While it is unlikely that this balance of cooling and heating demand will happen often throughout the year, energy efficiency can be greatly improved when the scenario occurs.
7 Reasons to Choose VRF HVAC Technology for Your New Air Conditioning
If you’re considering replacing the HVAC system in your Egypt commercial space or high-end residence, there’s a new type of HVAC technology on the market that you need to know about. It’s called Variable Refrigerant Flow (VRF) and it’s the latest and greatest in heating and cooling comfort.
These are the advantages of a VRF system:
Consistent comfort
Quiet operation
Energy efficiency
Installation flexibility, great for tight spaces
Heat & cool simultaneously
Zoned heating & cooling
State-of-the-art controls
Fewer breakdowns/less downtime
What is a Variable Refrigerant Flow or VRF HVAC system?
Here in the Egypt, many people are hearing about them and wondering what is a VRF system. But VRF systems have actually been around for decades.
Variable Refrigerant Flow, or VRF HVAC systems, has been the HVAC system of choice in Europe, Japan, China and other parts of the world for quite some time. Over the past 5 to 10 years, VRF HVAC technology has become increasingly popular in Egypt .
