Mesurement of Isobaric Heat Capacity for R 134a and Carbon Dioxide by Using a Flow Calorimeter(Thermal Engineering)

Heat Stroke and Carbon Dioxide

Experimental Study On R-134A Condensation Heat Transfer Characteristics In Plate And Shell Heat Exchangers

In this study, condensation heat transfer experiments were conducted with two types of plate and shell heat exchangers (P&SHE) using R-134A. An experimental refrigerant loop has been established to measure the condensation heat transfer coefficient of R-134A in a vertical P&SHE. Two vertical counter flow channels were formed in the P&SHE by stacking three plates of geometry with a corrugated tr...

Ventilation Flow in Pig Houses measured and calculated by Carbon Dioxide, Moisture and Heat Balance Equations

Ventilation flow in commercial livestock buildings can be estimated by means of relatively simple indirect methods based on carbon dioxide (CO2), moisture or heat balances. However, ventilation flow on an hourly basis for these balances needs adjustment for diurnal variation in animal CO2 and heat production. This work examines the agreement between ventilation flow measured in a pig house over...
