An innovative refrigeration system incorporating phase change material (PCM) is proposed to maintain refrigerated trucks at the desired thermal conditions. The advantage of using PCM to maintain low temperatures is that a conventional refrigeration system does not have to be located on-board the...

This paper presents an experimental study of the effects of tar on the performance of SOFCs with Ni/GDC anodes. Various operating temperature levels (700, 800 and 900°C) under both dry and wet conditions were employed in this study. Polarization behavior, electrochemical impedance spectroscopy,...

In this paper, we report on an underground water-source water-loop heat-pump (UWSWLHP) air-conditioning system for a tall apartment building in Beijing. Water at 14 °C was used as an external low-temperature heat-source. By analyzing field-test data for two years, the authors assessed the...
