Eutectic molten salt can be used as the latent thermal energy storage (LTES) medium in solar energy applications. In the present study, eutectic salt (50wt% NaNO3, 50wt% KNO3) with a melting temperature of about 220°C was employed as the PCM for the middle-temperature solar energy application,...

The utilization of paraffin in the latent thermal energy storage (LTES) system for solar energy storage is hampered by its low thermal conductivity. Paraffin/nickel foam and paraffin/copper foam composite phase change materials (PCMs) were prepared using a vacuum impregnation method in the...

A cold storage air-conditioning system using tetra-n-butyl ammonium bromide (TBAB) clathrate hydrate slurry (CHS) as cold storage medium was built to investigate the high-efficiency method of TBAB CHS generation. In the present study, four kinds of different TBAB CHS generation methods were...

To solve the overheating problem caused by the solar radiation and to keep the indoor temperature and humidity at a proper level for plants or crops, cooling technologies play vital role in greenhouse industry, and among which evaporative cooling is one of the most commonly-used methods....

A thermochemical resorption refrigeration system was designed and two types of application were investigated: (1) cold storage and (2) long-distance refrigeration. Manganese chloride and ammonium chloride were used as high-temperature salt (HTS) and low-temperature salt (LTS), respectively, and...

A novel chiller with open-cycle rotary desiccant cooling has been investigated experimentally. The technologies of two-stage dehumidification and regenerative evaporative cooling have been integrated together in this chiller. The objective of this study is to extend the ability for handling...

In order to optimize design and operation strategy of air-source heat pump water heater, an experimental set-up and simulation model were constructed. Also, a methodology of optimizing operation, which takes into account thermostatic and timing control patterns, was presented and applied....

A chemisorption air conditioner with NaBr/expanded graphite composite sorbent and NH3 as refrigerant was designed and constructed to be powered by low temperature heat. The effect of independent variables (chilled water inlet temperature, heat source temperature and cycle time) on the...

Solar powered solid desiccant cooling system is a good alternative to conventional vapor compression system. In this paper, a novel solar driven desiccant coated heat exchanger cooling (SDCC) system is proposed. In order to validate the feasibility of such system and to predict system...

A consolidated composite sorbent made from manganese chloride and expanded graphite was produced for sorption deep-freezing processes and used for cold production at a temperature as low as -35 °C. Experimental results showed that the addition of a porous graphite matrix can prevent the...
