Hvac Vrf Air Conditioning System Diagram
The term variable refrigerant flow refers to the ability of the system to control the amount of refrigerant flowing to the.
Hvac vrf air conditioning system diagram. Performance rating of variable refrigerant flow multi split air conditioning and heat pump equipment ieer has been established as a measure of the cooling produced for the amount of energy required to produce it in btu per watt per hour. Vrf is a technology that can reduce energy losses and thus improve air conditioner efficiency in certain installations. It is a ductless air conditioning system configuration where one outdoor unit condenses refrigerant and supplies the refrigerant to multiple indoor units. Learn about the most common hvac systems and.
Complexity is the name of the game when describing the technical nature of how variable refrigerant flow technology works. Like ductless minisplits vrfs use refrigerant as the cooling and heating medium. It s a very sophisticated technological air conditioning system based on several principles. The term variable refrigerant flow refers to the ability of the system to control the amount of refrigerant flowing to each of the evaporators enabling the use of many evaporators of differing capacities and configurations individualized comfort control simultaneous heating and.
An air handler is usually a large metal box containing a blower heating or cooling elements filter racks or chambers sound attenuators and dampers. Air handling unit ahu. Integrated energy efficiency ratio ieer per air conditioning heating and refrigeration institute s ahri standard ahri 1230. Variable refrigerant flow vrf system efficiency is not covered in 2015 iecc but is in ashrae standard 90 1 2013 building energy codes program 14.
Variable refrigerant flow vrf systems consist of outdoor units connected to multiple indoor units via refrigerant piping to provide cooling and heating to individual zones. Refrigerant only where refrigerant is the only coolant material in the system in contrary to the chilled water systems where refrigerant is used for cooling heating the water that is circulated throughout the whole system. Variable refrigerant flow vrf systems variable refrigerant flow vrf is an air condition system configuration where there is one outdoor condensing unit and multiple indoor units. Here s the definition according to ashrae.
A device used to condition and circulate air as part of a heating ventilating and air conditioning hvac system. What is a variable refrigerant flow vrf air conditioning system. This refrigerant is conditioned by a single or multiple condensing units which may be outdoors or indoors water or air cooled and is circulated within the. Air conditioning hvac systems as they relate to energy code requirements.
This arrangement allows for customizable comfort control while simultaneously heating and cooling for each area in the.
