چکیده
The purpose of the study is a comparative analysis methods for graphic analytical determination characteristics moist air in multistage compressors. Two are compared, which differ used I-d-diagrams: unified terms pressure and atmospheric. I-d-diagrams from atmospheric ones by diagrams saturated relative humidity () only at various pressures. For compressors, curves plotted on compressed intercoolers receivers. It assumed that isobaric cooling condensation its water vapor occurs coolers receivers final compression previous compressor stages. method, uses pressure, involves diagram plotting grid curves. An example such two-stage with an intercooler receiver given. A detailed description thermodynamic state nodal points processes pressure-unified I-d-diagram according to known values moisture content temperature. temperature end calculated equations polytropic process n = 1.26. dew cooler graphically defined as intersection pressures corresponding straight lines constant technique using (barometric) absence suitable pressure. essence developed determine I-d-diagrams, coinciding numerical application advantages disadvantages both evaluated.

Power Consumption Characteristics of Industrial Air Compressors
Compressed air is typically one of the most expensive utilities in an industrial facility. As a result, potential savings opportunities are aggressively sought out and identified. Once identified, projected energy savings must be calculated in order to justify the cost of implementing the savings opportunity. It is important to calculate projected energy and cost savings as accurately as possib...
متن کاملPower Characteristics of Industrial Air Compressors
The power draw characteristics of air compressors are primarily determined by the type of compressor control and the relationship between the compressor’s output capacity and the compressed air demand in the plant. In this paper, we review the most common types of compressor control for small reciprocating and rotary air compressors, and derive relations for estimating compressed air output as ...
متن کاملMethods for Determining Aldehydes in Air
Several reviews have been written on the various methods for the measurement of aldehydes in the environment [8,11,21]. These methods may be classified into two groups namely direct and indirect methods. Direct methods analyse the aldehydes during collection and therefore show great potential as the risk of sample contamination is greatly reduced. However, the cost and complexity of the instrum...
متن کاملElement Interactions and Dynamic Behaviour of Multistage Intercooled Reciprocating Compressors - an Analytical and Experimental Study
This paper describes a model which can simulate the dynamic behaviour 'Of a multi stage, intercooled reciprocating compressor. A mathematical model was derived for each element of such a system, accounting for entropy changes due to friction or uther irreversible processes. Numerical solution of the model was effected on a digital computer using discrete time steps and a quasi -steady approach....
