Is Your Exhaust Air Heat Pump Climate-Ready™?
Exhaust air heat pumps are a cutting-edge solution for mainly new residential homes, offering energy recovery while providing ventilation. Modern, energy-efficient homes can benefit greatly from this technology.
However, these heat pumps face several critical challenges. The need to boost capacity, higher demands for efficiency, and reduced CO2 emissions are some of the key drivers. Key challenges include optimizing performance across the operating envelope, managing variable speed compressors, water pumps, and fans, and addressing the use of flammable refrigerants like R290 (Propane). Boosting the capacity is crucial for mitigating energy loss during defrost cycles as well as allowing for maximized capacity using natural refrigerants with minimal refrigerant charge. Maximizing overall system performance and Seasonal Coefficient of Performance (SCOP) by minimizing the need for electrical booster heaters.
Heat Transfer Technologies to Elevate Performance and
Sustainability
Our heat transfer solutions are designed to tackle these challenges effectively. Our CFD-optimized channel plates enhance overall performance by perfectly adapting heat transfer to the specific conditions of the full operating envelope. Additionally, our design accommodates for the use of natural refrigerants such as R290 (Propane). Our heat exchangers feature an asymmetric design, where the channels are meticulously developed to balance refrigerant charge, performance, and water pressure drop. This allows for minimal use of refrigerant in the system while maximizing the capacity and maintaining system stability. Moreover, our heat exchangers are optimized for variable speed operation, ensuring efficient refrigerant distribution and maximum utilization of the heat transfer area across the full operating envelope.
By addressing these critical challenges with our innovative solutions, we provide engineers with the tools they need to achieve superior performance and sustainability in Exhaust Air Heat Pump systems.
