This paper describes the design and performance analysis of a variable-capacity heat pump system developed for a small [1800ft (167 m)] prototype net ZEH with an average design cooling load of 1.25 tons (4.4 kW) in five selected US climates. The heat pump integrates space heating and cooling, water heating, ventilation, and humidity control (humidification and dehumidification) functions into a...

Humidification-dehumidification (HD or HDH) desalination, and specifically HD driven by a thermal vapor compressor (TVC), is a thermal desalination method that has the potential to produce potable water efficiently in order to address the growing demand for water. This article presents a numerical study and optimization of two HD-TVC cycle configurations in order to determine the best achievabl...

HDH seawater desalination technology has characteristics of flexible scale, small investment, and suitable for decentralized fresh water demand. This paper designs a system, based on the principles energy conservation mass conservation, theoretical calculation model is established, influence spray liquid flow temperature, airflow, cooling temperature system production Gained output ration (GOR)...

This project presents the development of an algorithm predicting ambient greenhouse air conditions to be used for energy efficiency simulation and control schemes optimization. The climatic conditions considered are temperature, relative humidity, CO2 concentration and solar radiation. The algorithm has two modes of operation, the first simulates the greenhouse while in the second the heating, ...
