Abstract
The escalation of energy costs and conservation concerns demand improvements in the applications of energy consumption. Therefore, development of improved methods to increase the efficiency of greenhouse dehumidification is necessary. In this experiment, a controlled environment dehumidification unit was designed based upon doublepolyethylene greenhouses. The inside dry-bulb temperature and relative humidity were maintained near 65°F and 85%, respectively. The efficacy of the proposed design is limited to outside dry-bulb temperatures that are less than the dew-point temperature within the greenhouse. Testing of this dehumidification unit prototype will determine the accuracy of the theoretical design model and the feasibility of using a full-scale system. Accurately measuring humidity in structures is difficult, and the needed accuracy of measurements could not be obtained from this experiment to validate the theoretical model.
