Numerical Investigation of a Novel Plate-Fin Indirect Evaporative Cooling System Considering Condensation

نویسندگان

چکیده

An indirect evaporative cooling system combining with thermoelectric technology (i.e., TIEC system) is proposed, in which a counter-flow plate-fin cooler inserted TEC) modules. In hot and humid climate, condensation may occur on the dry channel surface of cooler. For system, aid TEC technology, temperature can be much lower than that traditional cooler, thus, from primary air more likely to take place. A numerical model this novel developed specifically taking into account. Detailed performance analysis carried out. Analytical results found reduces dew point effectiveness by up 45.0% weakening sensible heat transfer but increases coefficient 62.2% increasing latent transfer, under given conditions. The effects main operating conditions, such as electrical current I number n modules, inlet Tp,i, humidity ratio RHp velocity Vp air, mass flow rate x secondary are investigated non-condensation states. It shown condensate easily produced higher I, n, RHp, Vp.

Numerical Optimization of Pin-Fin Heat Sink with Forced Cooling

This study presents the numerical simulation of optimum pin-fin heat sink with air impinging cooling by using Taguchi method. 9 L ( 4 3 ) orthogonal array is selected as a plan for the four design-parameters with three levels. The governing equations are discretized by using the control-volume-based-finite-difference method with a power-law scheme on the non-uniform staggered grid. We solved th...

Optimization of Solar Absorption Cooling System Considering Hourly Analysis

Thermal modelling and optimal design of a solar absorption cooling system are presented, and hourly analysis is performed over the period of a year. Three design parameters are considered, then the Real Parameter Genetic Algorithm (RPGA) is applied to obtain the minimum total annual cost. The optimization results show that the solar cooling optimum configuration needs 1630 square meter collecto...
