Numerical study of a hybrid absorption-compression high temperature heat pump for industrial waste heat recovery (2017)
Journal Article
Ma, Z., Bao, H., & Roskilly, A. P. (2017). Numerical study of a hybrid absorption-compression high temperature heat pump for industrial waste heat recovery. Frontiers in Energy, 11(4), 503-509. https://doi.org/10.1007/s11708-017-0515-1

The present paper aims at exploring a hybrid absorption-compression heat pump (HAC-HP) to upgrade and recover the industrial waste heat in the temperature range of 60°C–120°C. The new HAC-HP system proposed has a condenser, an evaporator, and one mor...

Study on solidification process of sodium acetate trihydrate for seasonal solar thermal energy storage (2017)
Journal Article
Ma, Z., Bao, H., & Roskilly, A. P. (2017). Study on solidification process of sodium acetate trihydrate for seasonal solar thermal energy storage. Solar Energy Materials and Solar Cells, 172, 99-107. https://doi.org/10.1016/j.solmat.2017.07.024

The phase change of sodium acetate (SA) aqueous solution to sodium acetate trihydrate (SAT) requires large supercooling degree, then the aqueous solution can be at liquid state at fairly low temperature without releasing the stored latent heat. Such... Read More about Study on solidification process of sodium acetate trihydrate for seasonal solar thermal energy storage.

A chemisorption power generation cycle with multi-stage expansion driven by low grade heat (2017)
Journal Article
Bao, H., Ma, Z., & Roskilly, A. P. (2017). A chemisorption power generation cycle with multi-stage expansion driven by low grade heat. Energy Conversion and Management, 150, 956-965. https://doi.org/10.1016/j.enconman.2017.07.032

Ammonia-based chemisorption cycle driven by low grade heat exhibits vast potential for power generation because there exists huge pressure difference between the two salt-adsorbent-filled reactors. However, the intrinsic feature of ammonia as a wet f... Read More about A chemisorption power generation cycle with multi-stage expansion driven by low grade heat.
