A thermal liquid desiccant air handling machine was procured, installed, and field
tested. The goal of the present investigation is to evaluate the field performance of the
machine and characterize its operation for the temperature range of a solar thermal
array. The system studied includes a natural gas boiler supplying the heat, and a
cooling tower for heat rejection. System performance was evaluated for the 50 to 90 C
temperature range, the operating range of solar thermal collectors. Cooling power
varied between 4.3 kW and 22.8 kW for this range of temperature, with a latent heat
ratio between 1.1 and 1.9, confirming that the unit is significantly dehumidifying the
process air stream. Electrical COP varied between 0.58 and 4.48. Performance data
indicates higher temperature solar collectors such as evacuated tube or double glazed
flat plat collectors would be optimum in a solar cooling application with this system.
Empirical correlations for the regenerator and conditioner components were obtained
using a multivariate linear regression model. 5 empirical relations were derived and
can be used to characterize the thermal dehumidification concept. These relations
and methods will be used in future work to simulate and optimize a solar thermal
driven dehumidification system for dedicated outdoor air systems. / Thesis (Master, Mechanical and Materials Engineering) -- Queen's University, 2008-09-28 04:36:36.26
