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...
According to the application of radiant floor heating, system design, and laying status, this paper advances a design idea of using natural cooling source such as ground water or evaporation cooling water for `free cooling'. Based on the above, a mathematic model of low-temperature radiant floor heating/cooling is constructed. This paper studies the matching of radiant floor's cooling capacity and...
This paper describes an application of adaptive neuro-fuzzy inference (ANFI) to predict the performance of a cooling tower. In order to gather data for training and testing the proposed ANFI model, an experimental cooling tower was operated at steady state conditions. Utilizing some experimental data for training, an ANFI model based on a standard back propagation algorithm was developed. The performance...
