Proposed Session Description
Case study for the design of VRF HVAC for a 40 story building in Brooklyn. Challenges included reaching maximum piping lengths, dealing with acoustical restrictions and overcoming airflow problems with closely spaced condensers using CFD analysis. An additional challenge is the design of access to piping and wiring in large condenser farms.
Learning Objectives
Plan for design of VRF using long distances between condensers and fan coils.
Plan for acoustical design and become aware of these limitations with regard to the location of the condenser farms.
Use CFD analysis to use minimum space for airflow around condensers in order to maximize the number of condensers in a specified area.
Design raised dunnage or supports to manage and access large quantities of refrigeration piping and electric wiring needed for dense condenser farms.

Full Description
Design of VRF systems is a key component in the electrification and decarbonization of buildings. One building type that has struggled to make use of VRF is high rise residential. In geographical areas in the Far East, buildings are designed with balconies or setbacks specifically designed to accommodate VRF condensing units. However, in dense markets like NYC, architects and owners do not like the aesthetics and space constraints of mechanical balconies and thus long lengths of piping are required. Additional problems to be overcome include reaching maximum piping lengths, dealing with acoustical restrictions and overcoming airflow problems with closely spaced condensers using CFD analysis.
