A human being spends approximately one-third of his/her life in sleep. Sleep can help people overcome tiredness, and is very important to one's memory. With the gradual understanding of the influence of thermal parameters in a sleeping environment on the quality of sleep, different thermal...

Being environmental friendly and with the potential of energy-efficiency, more and more ground-source heat pump (GSHP) systems are being widely used. However, the influence of groundwater advection on the performance of the geothermal heat exchanger (GHE) in a GSHP is not still clearly known. In...

A bed-based TAC system applied to sleeping environments has been developed and its performances experimentally and numerically studied, and the study results are reported in this paper. Firstly, a detailed description of an experimental rig for the bed-based TAC system at two settings is...

The performance of a novel dry-expansion evaporator developed for a wastewater source heat pump (WWSHP) was experimentally tested and the test results are reported. The evaporator is a retrofitted shell and tube heat exchanger where bio-fouling build-up on tube surface can be easily removed from...

An artificial neural network (ANN)-based dynamic model for an experimental variable speed direct expansion (DX) air conditioning (A/C) system has been developed, linking the indoor air temperature and humidity controlled by the DX A/C system with the variations of compressor and supply fan...

A complete set of calculation method for steady-state equipment sensible heat ratio (SHR) for a direct expansion (DX) cooling coil has been developed and reported. The method was based on the fundamentals of energy conservation and heat and mass transfer taking place in the DX cooling coil, and...
