Methods of Testing Capacity of Refrigerant Solenoid Valves

Abstract

This standard is applicable to refrigerant solenoid valves in the following circumstances:

a.

As defined in Section 3, "Definitions"

b.

For either liquid or vapor refrigerant applications

c.

For use with refrigerants deemed available and suitable according to ANSI/ASHRAE Standard 15, Safety Standard for Refrigeration Systems1, and ANSI/ASHRAE Standard 342, Designation and Safety Classification of Refrigerants.

This standard specifies procedures, apparatus, and instrumentation that will produce accurate capacity data.

This standard does not do the following:

a.

Specify rating conditions or electrical or mechanical design requirements (Rating conditions may be found in ANSI/AHRI Standard 760, Performance Rating of Solenoid Valves for Use with Volatile Refrigerants3, for I-P units, or ANSI/AHRI Standards 761, Performance Rating of Solenoid Valves for Use with Volatile Refrigeratants4, for SI units.)

b.

Make recommendations for safety

c.

Specify tests for production, specification compliance, or field testing of solenoid valves

PURPOSE

This standard prescribes a method of testing the capacity of refrigerant solenoid valves for use in refrigerating systems.
