This paper investigates the performances of ventilation systems with desiccant wheel cooling from the perspective of exergy destructions. Based on the inherent influencing factors for exergy destructions of heat and mass transfer and heat sources, provide guidelines for efficient system design. First, performances of a basic ventilation system are simulated, which is operated at high regeneration...
Based on the database of typical weather condition in northern cold region of China, this paper compares different function buildings' cooling and heating load's imbalance rate. The effect of different building functions on cooling and heating load is analyzed. On the above basis, underground heat exchanger pipe group model of ground source heat pump (GSHP) is established. As a monthly time step to...
This paper considers the centralized energy supply system model which include the winter heating and summer cooling, The author carries on the analysis and the computation through the compressor, condenser and evaporator's power, the heat transfer and the flow quality, then establishes a steady-state mathematical model of water Source Heat Pump, which applied thermodynamics theory, the parameter distribution...
The project team apply the design software on virtual instrument terrace to develop the testing equipment and host computer software possessing general function. In the application instance, making the water resource heat pump machine set as the testing object .The testing equipment and host computer software cover the physical quantity and parameter required to be tested during the testing procedure...
This paper describes an application of artificial neural networks (ANNs) to predict the performance of a ground-water heat pump system (GWHP). In order to gather data for training and testing the proposed ANN model, an experimental GWHP system was operated at steady state conditions. Utilizing some experimental data for training, an ANN model based on a multi-layered perception/back propagation was...
