This experimental dataset for Integrated Solid Desiccant Packed Bed-Oscillating Heat Pipe System contains raw temperature data obtained from Fully Packed Bed (FPB), Small Annulus Packed Bed (SAPB), Medium Annulus Packed Bed (MAPB) and Large Annulus Packed Bed (LAPB) all respectively integrated with Helically Coiled Oscillating Heat Pipes (HCOHPs) charged respectively with Ethanol (EOHP), Methanol (MOHP), and Deionized Water (WOHP). The packed beds were filled with silica gel (Silicon Dioxide/SiO2) of particle size between 3.35mm-4.75mm. The annulus packed beds were in Heggs et al (1994) Z configurations described by their annular dimensions as small (SAPB), medium (MAPB) and large (LAPB) corresponding to diametrical ratios (Do/Di) of 2, 2.35 and 3.08, respectively. The data are mainly raw temperature data from Omega K-type thermocouples inserted in three designated Mass Transfer Zones (MTZ 1, MTZ 2 and MTZ 3), corresponding Walls (Wall 1, Wall 2, and Wall 3), Evaporators (Evap), Condensers (Cond), and Adiabatic Sections (Adiab) of each HCOHP integrated with a packed bed. Each packed bed was integrated with three (3) HCOHPs containing the same working fluid. Each HCOHP had two (2) thermocouples on their adiabatic sections and three (3) thermocouples installed on their evaporators and condensers respectively. The HCOHPs were numbered 1, 2 and 3 and the position of thermocouples on each component were labelled a, b, and c. For instance, the first evaporator would be labelled Evap_1 and where the thermocouple is located can be identified by say Evap_1a indicating the thermocouple is on the first position on the 1st evaporator. The ambient temperature data are also presented for each integrated system. The inlet and outlet pressures of each packed bed obtained as electrical pulses in Voltage and converted into Pascal (Pa) are captioned as Derived Pressure in Pa. Inlet and outlet air temperature, velocity and relative humidity obtained from Sentry ST732 Hotwire Anemometers and AZ 8829 Temperature and RH% data loggers are on the Inlet and Outlet Data Tabs. The dataset has seven (7) spreadsheets each for a packed bed configuration type integrated with the EOHP, MOHP or WOHP. For instance, for SAPB integrated with the HCOHPs i.e., EOHP, MOHP, and WOHP respectively, the combinations are SAPB-EOHP, SAPB-MOHP and SAPB-WOHP respectively. Each combination is presented on separate Tabs on the spreadsheet with its test run number such as SAPB-EOHP 1, SAPB-MOHP 1 and SAPB-WOHP 1 for test run 1 and SAPB-EOHP 2, SAPB-MOHP 2 and SAPB-WOHP 2 respectively for test run 2. The annulus packed bed configurations integrated with the HCOHPs have data for two test runs presented. Only one test run data is presented for the fully packed bed (FPB) namely FPB-EOHP, FPB-MOHP and FPB-WOHP respectively with respective inlet and outlet conditions data.
