The Copper Development Association (CDA) released research summaries on next-generation heat exchangers. The new three-part white paper gives industry professionals the most current insights on enhancing efficiency of HVAC&R systems using smaller diameter copper tubes. New systems based on these designs may give owners and engineers the opportunity to reduce operational costs and energy consumption.
Researchers from Optimized Thermal Systems, Inc. OTS used Multi-Objective Genetic Algorithm (MOGA) simulations to identify optimal heat exchanger designs in PTAC systems and Sub-Zero refrigeration systems. The PTAC studies particularly identified new condenser designs with smaller diameter copper tubes that can reduce both energy consumption and operational cost for PTAC systems, which are widely used in hospitality and some commercial applications. The Sub-Zero refrigeration study also used MOGA to find condenser designs that could reduce internal volume and total system charge while also maintaining or exceeding current performance levels.
These design identifications improve the progression and development of modern HVAC&R systems. “The exciting conclusions drawn will help minimize the volumes of energy exerted by HVAC&R systems,” said Kireta Jr., “they reflect copper’s inherent material advantages across a wide range of applications from plumbing, to energy and architecture.”
