Résumé

Water heating and indoor latent cooling loads are great sources of primary energy consumption in many applications. Recently, a semi-open ionic liquid absorption heat pump water heater (AHPWH) has been proposed in which the latent energy in humid air (ventilation, process air, etc.) is used to heat water. This APHWH operates at near ambient pressure, using a novel ionic liquid, enabling stable operation across a wide range of conditions using inexpensive and passive controls eliminating the complexities and costs associated with typical absorption cycles. In this work, we experimentally compare the performance of three configurations of the semi-open heat pump water heater internal heat recovery, at several conditions, including those representative of the standard rating tests as applied to commercial storage-type water heating equipment, to determine their impact on system capacity, coefficient of performance (COP), and water delivery temperature. The results suggest that the impacts varies with the inlet air dewpoint temperature and are substantial at low dewpoints. In hot and humid inlet air conditions, the combined COP reached to 2.55 with a 52 °C water delivery temperature. In these same hot and humid inlet air conditions, the combined COP decreased to 1.93 as the delivery water temperature was increased to 82 °C. These measurements demonstrated the viability of this technology in hot water-intensive applications such as commercial kitchens and food and beverage processing facilities.
