A comparative study of CO2 heat pump performance for combined space and hot water heating
(Journal article; Peer reviewed, 2019-08-20)
Heat pumps used for combined space and hot water heating are often used in modern energy-efficient buildings. Performance depends on both system design (exchanger sizes, compressor efficiency, etc.) and operating conditions (inlet water temperature, ratio between space and water heating, etc.). Designs using both CO2 and HFCs, such as R410A, are available, but the relative performance of these is ...
Droplet distribution spectrum effects on dry ice growth on cylinders
(Journal article; Peer reviewed, 2019-01-06)
A detailed parametric analytical study along with a series of viscid multiphase numerical simulations of ice accretion were performed in comparison with experimental data of ice accretion on a 30 mm diameter cylinder. The study was performed for droplet distribution spectra, Langmuir (A-J), in addition to an experimental droplet distribution obtained in an icing tunnel.<br>Analysis shows that droplet ...
