A real case study of an energy system based on a Solar Assisted Heat Pump (SAHP) fed by hybrid photovoltaic-thermal solar panels (PVT) and seasonal storage (SS) is presented in this paper. Exergy exergy cost analyses are proposed as complementary methods for the assessment better understanding efficiency cogeneration configuration. The performance takes advantage heat summer, when resource high...

This work presents the materials selection process, design and dimensioning process of a latent heat storage tank that works between high temperature pump an Organic Rankine Cycle unit. The selected material is S117 Phase Change Material has melting point at 117°C matches operational system approximately 120°C. configuration for optimised transfer resulted from practical experience project part...

In the energy transition, multi-energy systems are crucial to reduce temporal, spatial and functional mismatch between sustainable supply demand. Technologies as power-to-heat (PtH) allow flexible effective utilisation of available surplus green electricity when integrated with seasonal heat storage options. However, insights methods for integration PtH in lacking. Therefore, this study, we dev...

Frequency-swept pulses have recently been introduced as pump pulses into double electron-electron resonance (DEER) experiments. A limitation of this approach is that the pump pulses need to be short in comparison to dipolar evolution periods. The "chirp-induced dipolar modulation enhancement" (CIDME) pulse sequence introduced in this work circumvents this limitation by means of longitudinal sto...

Abstract In general two basic methods are used for controlling the velocity of a hydraulic cylinder. First by an axial variable-displacement pump for controls flow to the cylinder. This configuration is commonly known as a hydrostatic transmission. Second by proportional valve powered by a constant-pressure source, such as a pressure compensated pump, drives the hydraulic cylinder. In this stud...
