Temperature stratification using an air-cooled heat pump system with a mixing valve

Autor: Wang Kook Han, Jin Man Kim, Tae Hun Lim, Hae Eun Song, Young Chull Ahn

Publikováno v: Advances in Mechanical Engineering, Vol 12 (2020)

The main factor determining the performance of a thermal storage method is the temperature stratification in the storage tank. At the ideal stratification, the energy efficiency of the storage tank is extremely high. However, when the heat pump is ap

Numerical and Experimental Study of Air-to-Air Plate Heat Exchangers with Plain and Offset Strip Fin Shapes

Autor: Kyung Rae Kim, Jae Keun Lee, Hae Do Jeong, Yul Ho Kang, Young Chull Ahn

Publikováno v: Energies, Vol 13, Iss 21, p 5710 (2020)

This study evaluates the performance of a plate heat exchanger numerically and experimentally. The predictive model for estimating the heat transfer and frictional pressure drop across the plain and offset strip fins is compared with the experimental

Optimal Design of a Plenum Fan with Three-Dimensional Blades

Autor: Kyung Jung Lee, Il Wung Park, Ki Suk Bang, Yeong Min Kim, Young Chull Ahn

Publikováno v: Applied Sciences, Vol 10, Iss 10, p 3460 (2020)

We successfully designed an optimized plenum fan with a three-dimensional, smooth, curved blade. The optimized model revealed that the static pressure in the channel had been increased uniformly and stably, and the flow separation at the leading edge

Achieving Energy Self-Sufficiency in a Dormitory Building: An Experimental Analysis of a PV–AWHP-ERV Integrated System

Autor: Su-Kwang Yang, Yul-Ho Kang, Young-Chull Ahn

Publikováno v: Buildings, Vol 14, Iss 4, p 882 (2024)

In this study, we investigated the performance of air-to-water heat pump (AWHP) and energy recovery ventilator (ERV) systems combined with photovoltaics (PV) to achieve the energy independence of a dormitory building and conducted an analysis of the
