Splines are external and internal teeth, cut into the shaft and the installed part. The shaft and the installed part turn together. In many devices,the splines fit loosely. This allows the installed part to slide freely along the shaft while they turn. Splines may be straight or curved.

Lithium Bromide in absorption refrigeration system

Lithium Bromide ( LiBr) absorption refrigeration system water is used as refrigerant and Lithium Bromide is used as Absorbent. Lithium Bromide (LiBr) is a hygroscopic salt (Hygroscopic is the ability to attract and hold water from the surrounding). Water is absorbed by Lithium Bromide/water solution and drive off by using heat (Steam). As water is used in the absorption refrigeration system as refrigerant, so as the freezing point of water zero degree Celsius, so always keep the refrigeration temperature above zero degree. Application:  In industries where lower temperature is needed.
