A DEHUMIDIFYING HEAT PUMP FOR GREENHOUSES
Acta Horticulturae, 2012In heated greenhouses, attempts have been made to produce potted plants while reducing the amount of energy used. In fact, improvements in greenhouse structure and equipment (double walls, etc.) have led to better insulation and tightness. However, this tightness induces microclimatic changes, especially on night time humidity levels.

Continuous-flow thermoacoustic dehumidifier
The Journal of the Acoustical Society of America, 1998For applications in gas cooling a thermoacoustic refrigerator may be simplified by using the gas stream itself as the acoustic medium and eliminating the cold heat exchanger by directing the input gas stream through the stack (R. S. Reid et al., ‘‘Cyclic Thermodynamics with Open Flow,’’ Phys. Rev. Lett. to appear May 25, 1998).

Microcomputer Controlled Desiccant Dehumidifier
Transactions of the ASAE, 1987ABSTRACT Aprototype desiccant dehumidifier was built utilizing a horizontal, rotating drum containing solid desiccant. Outlet relative humidity was controlled by a microcomputer responding to various dehumidifier settings and environmental conditions. The system was tested using constant temperature and humidity inlet air.

Thermoelectric Dehumidifier for Sensor Cleaning
2021In this study, a dry and oil-free air system is developed using easily accessible commercial off-the-shelf components, streamlining the manufacturing process. The significance of this system lies in its ability to prevent contaminants in the air from leaving volatile residues that could potentially harm circuits and disrupt sensor accuracy.

Journal of Applied Electrochemistry, 2010
A two-layer model for a solid polymer electrolytic (SPE) dehumidifier is applied to a system in which the chamber to be dehumidified has some leakage area. By introducing this area, the attainable humidity in the chamber, which is the steady-state humidity to be attained after a long-time dehumidification, can be defined.

In the unit dehumidifier process, all or part of the condenser heat is used to re-heat the air leaving the evaporator. Since the moisture in the air has given up its latent heat in condensing, this heat is reclaimed and put back into the outlet air. The efficiency of a unit dehumidifier can be improved by a heat exchanger that pre-cools the incoming ...

Performance Optimization of Rotary Dehumidifiers
Journal of Solar Energy Engineering, 1995A rotary dehumidifier consists of a rotating porous matrix made of a desiccant with mechanically supporting materials. The dehumidification performance of a rotary dehumidifier wheel depends on its rotational speed, the sorption properties of the desiccant, the heat and mass transfer characteristics of the matrix, and the size of the dehumidifier.

Rotating ring desiccant dehumidifier
Journal of Agricultural Engineering Research, 1985Abstract Confinement animal housing on cold winter nights can consume large amounts of energy if sufficient airflow is used to control humidity. Reducing the airflow reduces energy consumption but causes excessive moisture to accumulate in the building.

Gas-powered liquid desiccant dehumidifier
Applied Energy, 1993Abstract A novel concept for the operation of a liquid desiccant domestic-dehumidifier has been proposed: the resulting developed system dehumidifies air by passing it directly over a liquid desiccant. The system is novel in two respects: first, a bubble pump is used to both reconcentrate the desiccant as well as pump it around the system; secondly ...

Corrosion Monitoring in Dehumidified Storage
CORROSION 2010, 2010Abstract Dehumidified storage areas are designed to eliminate moisture and thereby corrosion damage. The goal of a dehumidified storage system is to keep the relative humidity (RH) below a certain level (75%) whereby the adverse effects of humidity (rust, condensation, mold and mildew) are greatly reduced or eliminated.
