| 摘 要： | 根据气液两相流动的均相流假设,建立了绝热毛细管的分布参数模型.在冷热工况下空调系统制冷剂充注量差值的基础上,采用该模型模拟计算了应用毛细管节流的热泵型空调系统中主副毛细管的长度.将储液器法和采用主副毛细管控制制冷剂流量这两种方法进行了对比分析,结果表明,在控制系统高低压差和制冷剂流量时,两种方法各有利弊.因此,提出了采用主副毛细管和增加储液器相结合的方法控制热泵型空调系统冷热工况下的制冷剂流量.

| Abstract: | Based on the homogeneous assumption of gas and liquid two-phase flow,a distributed parameter model of adiabatic capillary tube was established.Based on the refrigerant charge inventory differences of air-conditioning system between refrigeration and heating conditions,the lengths of the major and associate capillary tubes in the capillary tube adjusting air-conditioning and heat pump system were simulated by using this model.The liquid reservoir method and the associate capillary method were analyzed.The re... |
