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...

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....

In this study, a small scale hybrid solar heating, chilling and power generation system, including parabolic trough solar collector with cavity receiver, a helical screw expander and silica gel-water adsorption chiller, etc., was proposed and extensively investigated. The system has the merits...

A solar-powered adsorption air-conditioning system was designed and installed in the green building of Shanghai Research Institute of Building Science. The system contained 150 m2 solar collectors and two adsorption chillers with nominal refrigeration capacity of 8.5 kW. Based on...

As a kind of distributed energy system, internal-combustion-engine-based cogeneration system is attracting increasing attentions for its environmental friendly and economic qualities. Some problems are encountered in the application, such as jacket water temperature control and the...

A novel operation strategy based on minimum distance was proposed. Also, an integrated evaluation criterion which can reflect the matching performance between the CCHP (combined cooling, heating and power) system and the building was presented. A hospital in Shanghai was used to evaluate the...

A novel micro CCHP system, which is based on a two bed silica gel-water adsorption chiller, is constructed in this work. To reveal the chiller characteristic in this system, a transient model of the adsorption chiller is developed. According to the comparison of the simulated results and...

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...
