in this paper, exergy of conditioned air, exergy efficiency, irreversibility, and entropy generation of common models of evaporative cooling have been investigated in five cities of iran. direct evaporative cooling (dec), indirect evaporative cooling (iec), and two-stage iec/dec as the most popular methods of cooling have been modeled. atmospheric conditions are considered as the dead state of ...

This study reports the findings of two classes of corneal afferents excited by drying of the cornea (dry responses) in isoflurane-anesthetized rats: cold-sensitive (CS; 87%) and cold-insensitive (CI; 13%) neurons. Compared with CI neurons, CS neurons showed significantly higher firing rates over warmer corneal temperatures (~31-15°C) and greater responses to menthol, drying, and wetting of the ...

This paper presents results of a parametric study performed on an automotive air-conditioning (AAC) system of a passenger car. The goals are to assess the effects of varying the volumetric flow rate of supply air, number of occupants, vehicle speed, and the fractional ventilation air intake (XOA), on the dry-bulb temperature and specific humidity of the air inside the passenger’s cabin, and on ...

this paper investigates the function of windcatchers in dry regions in middle east and compares them in different fields in two areas including yazd-iran, and egypt. the study examines windcatchers in these areas in terms of cooling system and forms, with different plans, forms, constituent components and decorations.reassessment of windcatchers in these areas can shed light on these difference...

This study investigates the effects of cutting parameters on surface roughness (Raμm ), cutting temperature (T0C) at the chip tool interface and the material removal rate (MRR mm3/min) during hard machining of AISI 1015 (43 HRC) steel using carbide insert under dry and spray impingement cooling environment. A combined technique using orthogonal array and analysis of variance (ANOVA) was employe...

Objectives Digital cryotherapy is commonly used for laminitis prophylaxis and treatment. Currently validated methods for distal limb cryotherapy involve wet application or compression technology. There is a need for a practical, affordable, dry cryotherapy method that effectively cools the digit. The objective of this study was to evaluate the hoof wall surface temperatures (HWSTs) achieved wit...

An experimental study has been conducted to evaluate the performance of a compact round-tube louver-fin condenser, each with frontal areas of 0.25 m in both dry and wet conditions. Deluge water cooling is achieved by incorporating a perforated bottom plate-type water distributor on top of the round tube heat exchanger. Water is used as a refrigerant, and enters the heat exchanger tubes at 35°C ...

A numerical model has been used to characterize the development of a region of 6 enhanced cooling, in an alpine valley with a width of order 10 km, under decoupled stable 7 conditions. The region of enhanced cooling develops largely as a region of relatively dry 8 air that partitions the valley atmosphere dynamics into two volumes, with air flows partially 9 trapped within the valley by a devel...
