5 1. PURPOSE
2. SCOPE
2.1 This standard covers cool storage systems composed of chillers, storage medium, storage device or vessel, heat sink equipment or heat sink systems, and other auxiliary equipment required to provide a complete and working system.
2.2 This standard includes
2.3 This standard does not cover testing of the air-side distribution.
3. DEFINITIONS
6 4. CLASSIFICATIONS
4.1 Discharge test measures the amount of cooling energy that can be delivered from the thermal storage device to meet the specified load profile.
4.2 Charge test measures the amount of cooling that can be stored in the thermal storage device within the time period available for charging.
4.3 Cool-storage system capacity test measures the amount of cooling energy that can be delivered by the system to meet the specified load profile. This test is identical to the discharge test if the thermal storage device is designed to provide full…
4.4 Cool-storage system efficiency test measures the cycle specific energy use of the system.

A1. Introduction
A2. Obstruction Sampling-Type Flowmeters
A2.1 Axial Turbine Meters. Axial turbine meters measure fluid flow by counting the rotations of the rotor that is placed in a flow stream. Axial turbine meters can be full-bore type or insertion type. Full-bore turbine meters have an axial rotor and …
A2.2 Vortex Meters. Vortex meters utilize the same physical effect that makes telephone wires oscillate in the wind between telephone poles. This effect is due to oscillating instabilities in fluid flow after it splits into two streams around a blunt…
A2.3 Insertion Magnetic Meters. Insertion magnetic meters use Faraday’s law of electromagnetic induction to facilitate the measurement of sampled flow. Insertion magnetic meters are available with single or multiple sensors per probe. Greater accur…
A3. Noninterfering Flowmeters
22 A3.1 Ultrasonic Flowmeters. Two basic types of ultrasonic flowmeters available for general use are transit time and Doppler. Transit-time ultrasonic flowmeters measure fluid velocities by detecting small differences in the transit time of sound waves…
A3.2 Full-Bore Magnetic Flowmeters. Magnetic flowmeters use Faraday’s law of electromagnetic induction to measure the average flow velocity in a pipe. Magnetic coils surround the flow, using a pulsed DC or AC generated field to produce a signal. Th…
