HVAC Variable Refrigerant Flow Systems

HVAC Variable Refrigerant Flow Systems Course No: M03-014 Credit: 3 PDH A. Bhatia Continuing Education and Development, Inc. 9 Greyridge Farm Court Stony Point, NY 10980 P: (877) 322-5800 F: (877) 322-4774 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. The term Variable Refrigerant flow refers to the ability of the system to control the amount of Refrigerant flowing to the multiple evaporators (indoor units), enabling the use of many evaporators of differing capacities and configurations connected to a single condensing unit. The arrangement provides an individualized comfort control, and simultaneous heating and cooling in different zones.

"variable refrigerant flow". In essence both are same. With a higher efficiency and increased controllability, the VRF system can help achieve a sustainable design. Unfortunately, the design of VRF systems is more complicated and requires additional work compared to designing a conventional direct expansion (DX) system.

Methods of Calculating Minimum Fresh Air Requirements

www.seedengr.com

If the occupancy of the building is known to be higher than the number calculated per floor area, then this number must be used to determine the minimum rate. Example: If five people were known to be using the computer room on a regular basis, the ventilation rate would be: Quantity of air (L/s) = Known occupancy rate x Rate/person (L/s) Solution:

Multiple Variable Speed Secondary Pumps. 2-way valves at all chilled water coils and secondary bypass loop with 2-way valve. • Each primary pump pumps water through a chiller. These can be piped so either pump can work with either chiller if isolation valves are used at each chiller or with dedicated primary pumps for each chiller.
