摘要
本文提出了一种新的非共沸混合工质连续容量调节制冷系统。它可根据室外温度的升降,很方便地增减循环中混合工质的浓度,经济地实现制冷量与用户动态冷负荷的匹配。该系统结构简单、操作方便、调节范围大,是一种较好的容量调节系统。
This papcr presents a new refrigeration system of continuous capacity control with non-azcotropic refrigerant mixtures(NARMs).The composition of the NARMS in the system can be changed automatically according to the alterations of the outdoor ambient temperature to match the refrigerating capacity to the consumcr's cool load curve without encrgy losses.Owing to this regulating characteristic,the intrinsic problem of the performance of the cycle with NARMs easily affected by the leaking of the working mixtures,one of the biggest problems blocking the application of NARMS,can be readily solved in this new system.The new system,which is simple in structure,convenient to operate,and economical in running,is indeed an ideal one of the capacity control systems.
