Paper No 130 – 1 Energy Performance Estimation and Verification of an Industrial Waste Heat Recovery Heat Pump – 13th IEA Heat Pump Conference, Jeju, Korea
Aiming to save primary energy, reduce greenhouse gas, and save running cost, it is important to construct systems in industrial factories more efficient by utilizing heat from warm wastewater. To realize more efficient water heating system, it is essential to develop and evaluate affordable direct heat-recoverable heat pump which has direct recoverable evaporator. An experimental performance evaluation and an estimation based on the results have been conducted. According to the evaluation, developed heat pump achieved a COP of 4 or more, with an warm wastewater temperature of 35°C. Verification of the estimation was conducted by the field measurement. A problem, performance degradation according to fouling of the evaporator. A solution was developed, and availability was validated through the field measurement.
