چکیده
The air compr8ssor 1~i th spr8.ying wfl.tP-r into cy1 inders can make its power consumption ann discharF,e temperature decrease but the effect of spraying ••ater to power consumption and discharge tempera~ ture is difficu1t to he quantitatively sho••ed 1dth rliffqrent starting condition. This paper establishs a formula to calculate the polytropic expon8nt in ideal compressing processes of spraying 1~ater becau:se the polytropic exponent Cfl.n clearly show the contribution to power con~ sumption and discharge temperature. In the formula, each parameter appears evidently its meaning and its effect to the polytropic expcn~ ent, and the result points out that the best way to decrease the poly~ tropic exponent is to increase the atomization effect in cylinders. Through analysing the formula, a spraying water parameter is found to show the spraying water result.

Experimental Study of the Heat Transfer Enhancement in Concentric Tubes With Spherical and Pyramidal Protrusions
In the current research project, the thermal performance of a series of newly designed mixers has been investigated. Each mixer has two concentric cylinders comprising two annular slot flow channels around a solid cylindrical rod at the center. In each mixer, the first cylinder around the central solid rod has either spherical or pyramidal protrusions throughout the outer surface. It has been o...
متن کاملTime Resolved Mass Flow Measurement for a Reciprocating Compressor
The instantaneous mass flow was measured during the intake and discharge processes of a reciprocating gas compressor (1)*. The purpose of these measurements was to identify the mechanism which caused a loss of adiabatic and volumetric efficiency that could not be accounted for by valve flow losses. The measurements were made wi ·th square-edged orifices and fast response differential pressure t...

In this work, an unsteady state analysis of the compression cycle of a small hermetic reciprocating compressor for domestic refrigeration was carried out. The mass and energy balances were applied to the refrigerant inside the cylinder in order to determine the mass and temperature behaviour through the compression process. A specific onedimensional model of the valves was developed to calculat...

In the present study oneand two-dimensional numerical models are proposed for calculating gas flow and valve dynamics in a reciprocating compressor. It turns out that they are capable of capturing the most important physical effects during a compression cycle, namely the interaction between pressure waves inside the cylinder and valve dynamics. In order to model the heat transfer from the gas t...
