Energy Savings of Cold Brine Heat Pump Systems

This technical report evaluates the energy efficiency of a Cold Brine Heat Pump for cold room and cold storage makeup air applications. It compares the performance of the Cold Brine Heat Pump against Multiple Condensing Unit and Desiccant Wheel systems. The report details the ability of the Cold Brine Heat Pump to deliver supply air at temperatures between 38°F and 50°F with a dew point depression of at least 10°F in a single pass. It quantifies energy savings of up to 40% and discusses environmental benefits such as reduced CO₂ emissions and the elimination of defrost cycles. The system architecture includes a refrigerator unit, concentrator unit, and heat recovery economizer, which work together to enhance efficiency. The report presents experimental data supporting the Cold Brine Heat Pump's performance, demonstrating lower electrical consumption and improved indoor air quality. It concludes that this system is a scalable and reliable solution for cold storage applications.
