A design platform named the Smart Thermal Energy Design (STED) platform has been developed for thermal energy-intensive industrial utilities, designed to be accessible to all users, including those without expertise. Among various design modules in the platform, the design module for vapor compression heat pumps provides appropriate design results under the required design conditions. The module has been demonstrated with a lab-scale heat simulator with an error of 0.1% in terms of mean COP for 30 minutes. Moreover, database of key components such as commercial compressors and expansion valves have been established to recommend the components based on the module design results.
