Achieving low return temperature for domestic hot water preparation by ultra-low-temperature district heating

Ultra-low Power Temperature Sensor

We propose an architecture and circuit for temperature sensors integrated within systems on a chip. The circuit is based on special properties of devices when biased by a current with a particular dependence with temperature. We present results from a test circuit fabricated on a standard 0.8 μm CMOS technology which draws under 40 nA from a 1.6 V to 3.0 V supply at room temperature. Measuremen...

Performances of Low Temperature Radiant Heating Systems

The low temperature radiant systems are very complex because they involve different mechanisms of heat transfer: heat conduction through the walls, heat convection between the heating panel and the indoor air, heat radiation between the heating panel and the surrounding areas, and the heat conduction between the floor and the ground. The main essence of the low-temperature air systems is to pro...

Inorganic Complex Precursor: Preparation of Cu-Mn/SiO2 Mixed Oxide Nanocatalyst for Low-Temperature Water-Gas Shift Reaction

The present study examined the effect of three methods of preparation on the properties and catalytic performance of Cu-Mn/SiO2 catalysts for the water gas shift reaction (WGSR). Impregnation and coprecipitation and the new approach of thermal decomposition of [Cu(H2O)6][Mn(dipic)2].2H2O/SiO2 inorganic precursor complex were used for the synthesis of the silica-supported copper-manganese mixed ...
