Humidification dehumidification desalination (HDH) is a promising technology for small-scale water production applications. There are several embodiments of this technology which have been investigated by researchers around the world. However, from a previous literature review [1], we have found no study which carried out a detailed thermodynamic analysis in order to improve and/or optimize the...

Solid dehumidification is one of the important components air-conditioning system. As an method solid dehumidification, performance and regeneration fixed-bed have impact on operation energy saving In view high air temperature humidity in South China, our design organically combines fixed beds, semiconductor refrigeration devices, foam ceramic insulation panels double-glazed windows. We designe...

Abstract For its efficient application of low-grade energy, the circulating wheel dehumidification air conditioning system has received a lot attention and research in response to shared challenges environmental protection, energy conservation, low carbon. Desiccant systems can recycle waste heat as desiccant regeneration source improve quality, which is expected achieve consumption high-effici...

Thermoeconomic diagnosis of refrigeration systems is a pioneering approach to the diagnosis of malfunctions, which has been recently proven to achieve good performances for the detection of specific faults. Being an exergy-based diagnostic technique, its performance is influenced by the trends of exergy functions in the “design” and “abnormal” conditions. In this paper the sensitivity of perfor...

This article describes the mechanisms affecting the thermal behavior of buildings. This behavior depends upon the temperature and humidity balance in premises. First the physical mechanisms of heat transfer are explained, followed by a description of the heat and humidity sources and sinks in premises. The next three sections deal with the physics of psychrometry, necessary for understanding th...

In recent years, the sensible heat load of buildings has been decreasing due to promotion energy conservation, and factor is expected decrease. response, conventional dehumidification method using overcooled condensation likely insufficient handle latent heat, an advanced required. The authors have focused these issues development on a membranes. Membrane systems (MDS) are relatively simple, th...

Exergy analysis emboldens in cases that all the inefficiencies and bottlenecks to improve energy systems are to be addressed. In this study, a novel vapor compression air dehumidifier integrated with an auxiliary heat exchanger in series arrangement with the main condenser in order to mitigate the reheat coil, and an extra mixing box to recover the ventilated air heat has been introduced. A com...

Nature uses air as a carrier gas to desalinate seawater through evaporation and rain. Several investigators have previously studied desalination cycles based on carrier gas processes. However, single pressure carrier gas cycles suffer from low energy recovery and hence low performance. Here we discuss a novel carrier gas cycle which operates under varied pressure. This cycle operates the evapor...
