以网络、图论为基础,建立了基于气液两相流体网络的制冷剂自然循环系统的数学模型,采用关联矩阵来描述各个部件之间的关联关系,通过对模型的求解,得出了冷凝器进口水温、冷却水流量、室内空气温度等参数对系统制冷量的影响规律。研究表明,当蒸发温度和冷却水流量不变时,随着冷凝器进口水温的降低,蒸发器的制冷量不断增大;当室内换热器风量和室内温度不变时,蒸发器的制冷量随蒸发温度的升高而减小。
Based on the network and graph theory, the mathematical model of natural circulation system of refrigerant based on gas-liquid two-phase fluid network was established. The correlation matrix was used to describe the relationship between the components. By solving the model, The inlet water temperature, cooling water flow, indoor air temperature and other parameters of the system cooling capacity of the law. The results show that when the evaporating temperature and the cooling water flow are constant, the cooling capacity of the evaporator increases with the decrease of the inlet water temperature of the condenser. When the indoor heat exchanger air volume and the indoor temperature are unchanged, the cooling capacity of the evaporator Decreases with increasing evaporation temperature.
