Scope

GB/T 23684-2009 is the English-translated version of 液管制冷剂干燥器的试验方法.

GB/T 23684-2009 — This standard specifies the test method to determine the fluid flow rate control refrigerant dryer and moisture performance characteristics. This standard applies to the use of a desiccant dryer.

Since the desiccant performance with its activity and changes in the water content of the test methods specified in this standard is applicable to both test "new dryer," also Built by the manufacturer applies to require re-activation through the desiccant dryer.

This standard applies to the use of halogenated hydrocarbon system refrigerant boiling below 20 °C under normal atmospheric pressure. This standard does not apply to the following performance indicators for the dryer.

Physical characteristics a) a desiccant; b) chemical properties of the dryer; c) absorbing mechanism of the dryer; d) the ability to filter dryer; e) for acid adsorption dryer; f) are not used for the dryer performance liquid pipelines; g) drying speed; h) by the size of the system, the potential problem of the freezing and chemical activities on the water content of the dryer; i) oil on dryer performance.

This standard does not specify a temperature, equilibrium point dryness, pressure drop and other standard conditions, these values \u200b\u200brefer ARI710 standards (see Appendix A).

What this standard covers

This standard specifies test methods for determining fluid flow control refrigerant dryer and moisture performance characteristics. This standard applies to the use of desiccant dryers. As the desiccant performance varies with activity, moisture content test methods specified in this standard applies both to test "new dryer, " also applies to the contents required by the manufacturer had reactivated desiccant dryers. This standard applies to the use of the system halogenated refrigerants boiling point below 20°C under standard atmospheric pressure. This standard does not apply to the dryer following performance indicators: the physical characteristics of a) desiccant, chemical characteristics b) of the dryer, absorbing mechanism c) of the dryer, d) the ability to filter drier, e) dryer acid adsorption, f) are not used for dryer performance liquid pipelines, g) drying speed, h) by the system size, affect i) oil on dryer performance, impact of potential freezing and chemical activities of the water content of the dryer. This standard does not specify the temperature, equilibrium point dryness, drop and other standard conditions, these values ??refer to ARI 710 standard.
