TL;DR: In this paper, 20 nm silica particles were dispersed into nitrates by ultrasonic stirring method to study the effects of different mass concentrations of nanoparticles on the thermal properties of nitrates.

TL;DR: In this article, the authors investigated the mechanism of heat and moisture transfer in soil heat charging for solar-soil source heat pump system, a testing rig of one-dimension soil heatcharging is constructed.

TL;DR: In this article, the thermal and electrical performance of PV panels with active cooling by attaching heat pipes beneath the PV panel, building up a PV-heat pipe (HP) combined system was studied.

TL;DR: In this paper, a simulation and experimental investigation on the early aspirated smoke detection system is carried out to analyze the response performance of fire detectors located at the smoke sampling pipes, and numerical calculation can forecast the response time of the system very well and it can be employed to guide the design and installation of ASD system in large space buildings.

TL;DR: In this paper, a centralized solar hot water system of residential area in Tianjin is studied, the mathematical model of the heat-collecting unit, heat-supply unit and heat-using unit were established, and the whole system was formed.
