SharePerformance and optimum for a ground-coupled liquid loop heat recovery ventilation system.
Author(s) : ZHOU Y., FAHLÉN P., LINDHOLM T.
Summary
Ground-source heat pump systems can be designed to include liquid-loop heat recovery ventilation (HRV), free cooling and recharging of the borehole collector. The HRV-system uses an exhaust-air coil to warm brine that has been preheated by a borehole heat exchanger. The warm brine then heats a supply-air coil and returns to the borehole. The performance of the exhaust-air and supply-air coils has an influence on the HRV system efficiency. This paper presents a mathematical model to investigate how the brine flow rate and the allocation ratio between the exhaust and supply-air coils affect the heat recovery efficiency.
