refrigerant line

In this paper,based on the experimental study on the influence of indoor and outdoor unit refrigerant pipe length on the performance of air-conditioning(heat pump) unit equipped with full fresh air duct,the variation rules of parameters,including cooling capacity,EER,discharge pressure,suction pressure,discharge temperature,refrigerant pipe pressure drop,etc.

本文通过进行全新风风管送风式空调(热泵)机组室内外机制冷剂配管长度对机组性能影响的实验,总结了机组制冷量、EER、排气压力、吸气压力、排气温度、制冷剂配管压降等参数随制冷剂配管长度变化的规律,分析了制冷剂配管长度对全新风风管送风式空调(热泵)机组性能影响的特点。

In order to improve the NGL recovery rate for some condensate gas fields, which had high pressure gas source and there was no differential pressure for utilization, this paper put forward a cryogen refrigeration-oil absorption combination process to recover NGL on the basis of cold oil absorption theory.

为了进一步提高天然气凝液装置的产品收率,本文针对凝析气田中气源压力高,无压差可利用的工况条件,应用冷油吸收原理,通过工艺流程模拟分析与研究,确定了冷剂制冷-油吸收复合凝液回收工艺原理流程。
