Qads depends on the actual application. For the heat pump is Qa(h = Qdes-For long-term TES, Qsens cannot be used due to thermal losses. For a desiccant cooling system only Qcond can be used during adsorption.

Thermally activated ceilings are used to heat and cool the building. In summer the ceilings are cooled by well water. Therefore humidity control is required to prevent humid air from condensating at the ceilings. The humidity is controlled by a solar driven liquid desiccant cooling and dehumidification... 

Predicted Energy Balance and Investment Costs of the Desiccant Cooling System... 

The desiccant cooling system can provide up to 20 MWh per year of cooling and dehumidification energy. This includes the energy delivered by the cold... 

The total investment costs of the desiccant cooling system including collector array, cold recovery, storage, and controls have been planned to be about 300,000 Euro, this is 2,000 Euro per kW respectively 10 Euro per (m3/h). The final costs have not yet been evaluated. 

The collector array and the components of the desiccant cooling system, such as dehumidifier, regenerator, storage and desiccant handling system, have... 

The liquid desiccant cooling system is designed, built and installed. A series of problems occurred and caused a significant time delay. Due to that time delay the demonstration project has to be stopped and no reliable data of the component test and the system operation could have been recorded. 

Energy Applications Desiccant cooling is a means for more efficiently providing air conditioning for enclosures such as supermarkets, ice rinks, hotels, and hospitals. Adsorbers are integrated with evaporative and electric vapor compression cooling equipment into an overall... 

The work of Collier at the University of Florida [14] produced the finding that a modified Brunauer type I isotherm, with a more modest degree of curvature to the isotherm, was the theoretical optimum for deep dehydration cycles that were expected to be used in open cycle desiccant cooling cycles. The adsorbent was dubbed a type IM (M for moderate). To understand this designation zeolite type X with its incredible steep isotherm is designated a type IE (E for extreme). 

Place the crucible in a muffle furnace at a temp of 750 —800 °C and permit to remain until all carbonaceous matter has been ignited, Remove from furnace cool for several mins in the atmosphere place in a desiccator cool further for 30 mins and weigh. Calculate the loss in weight to percentage of graphite as follows ... 

Collect the liquid silicon tetrachloride in a receiver flask provided with a calcium chloride tube or a wash bottle with a desiccator. Cool the receiver with a mixture of ice and table salt. 

Dry an aluminum weighing dish (and cover, if used) >1 hr at 105°C. Cool and store dried dish in a desiccator. Cool >30 min before using.
