A new composite thermochemical heat storage (TcHS) material was proposed herein with
good heat storage performance and desirable stability, which was prepared by using solid-…

Herein, we proposed a cascade refrigerant system with R1270 and carbon dioxide refrigerants.
The natural refrigerant R1270 was adopted in the high-temperature circuit to replace NH …

Compressor in air supply circuit influences flow rate of oxygen in cathode of polymer
electrolyte membrane (PEM) fuel cell systems. In this paper, an air-cooled dry oil-free twin-screw …

Auto-cascade refrigeration (ACR) systems are widely used at low temperatures. The selection
and ratio optimization of zeotropic refrigerants in ACR systems have an important impact …

Removing gaseous formaldehyde (HCHO) using photocatalyst oxidation is of great interest.
