High-Efficiency Heat Pump System Design and Optimization
Project Overview
The project focused on the development and optimization of a high-efficiency air-to-water heat pump system for industrial HVAC applications.
The initiative aimed to reduce energy consumption and carbon footprint while maintaining heating and cooling performance across variable climate conditions.
The design involved refrigerant circuit optimization, compressor selection, heat exchanger redesign, and full 3D CAD integration to ensure system reliability, manufacturability, and regulatory compliance.
Design Requirements
