This paper, MATALAB was used to simulate series-connecting of the ground-source heat pump and the solar collector. Firstly, the simulation models of heat pump unit, ground heat-exchanger and solar collector were established. Secondly, the dynamic simulation model of combined heating system under series-connecting mode was obtained through the established sub-models and mutual coupling relations. Finally,...
Natural Gas are often found at remote locations to bring it to the world market liquefaction is required. In liquefaction natural gas is cooled to around -160°C, hence required considerable amount of energy. To maximize the profit from the existing design it is necessary that the process should operate efficiently, reliably and safely. Hence a good and Robust control is required. Due to tight control...
To accurately obtain emulation model of a heat- exchanger, segment linearization was applied to the lumped parameter model: the whole heat-exchanger was divided several segments equally and became their connection. Each small heat- exchanger applied the lumped parameter model of segment linearization. At the same time, the whole heat-exchanger embodied distribution parameter's characteristics of several...
This paper takes CFBB as simulating object, which has characters of DG1025/17.4-II1 two legs furnace and with external heat exchanger. Combined with thermal process and combustion chamber working characteristics of practical unit, a general dynamic model arithmetic library of CFBB combustion chamber was set up based on a kind of graphic modeling real time simulating support system. In the arithmetic...
