ASHRAE 63.1
Method of Testing Liquid Line Refrigerant Driers
Year: 2001
Abstract: This standard applies only to those driers that employ a desiccant.
A desiccant's performance varies with respect to its activation. The water capacity test method prescribed in this standard can be used to test a drier either "as received" or after being reactivated in accordance with the manufacturer's recommendations.
This standard applies only to liquid line driers for use in systems employing halocarbon refrigerants that have an atmospheric boiling point below 20°C (68°F).
This standard does not attempt to reflect the complete performance of a drier. Specifically, the following topics are not considered:
a. the physical characteristics of the desiccants,
b. the chemical characteristics of the desiccants,
c. the mechanism of water adsorption,
d. the filtration ability of a drier,
e. the acid adsorption of a drier,
f. the performance of a drier in other than a liquid line,
g. the speed of drying, h. the drier water capacity needed in relation to the size of a system, potential freeze-up problems, or potential chemical activity problems, or
i. the effect of oil on a drier's performance.
This standard defines methods of testing but does not specify the standard rating conditions for temperature, equilibrium point dryness, pressure drop, etc. ARI Standard 7107 is suggested as a reference for these values.
PURPOSE
The purpose of this standard is to prescribe test methods for determining flow capacity and water capacity performance characteristics of liquid line refrigerant driers.
