Simulation of industrial refrigeration plants under variable load conditions

摘要: Abstract A method to simulate industrial refrigeration systems with several independent, time-variable heat loads is described. The uses a combination of ordinary differential and algebraic equations describe both the plant, its interaction product in each application. Numerical integration respect time allows various processes be simulated. Models for freezers, chillers, cold stores controlled atmosphere work areas are discussed. Assumptions made these models realistic from practical viewpoint, so provided accurate data available close correlation between predictions measurements would expected. simulation could have applications system control design as it will predict interactions different parts plant when operating under conditions. When considering changes or specifications suitability particular alternatives can assessed by simulating turn.
