Call for Members, April 2020

Call for Members: ASHRAE SSPC 41

Join ASHRAE SSPC 41 for Projects on Standard Methods of Measurements

From eSociety, April 2020

SSPC 41, Standard Methods of Measurement, is looking for members for two of its subcommittees, as follows: 

Subcommittee 41.7-2015R, Standard Methods for Gas Flow Measurement 

1. Purpose

This standard prescribes methods for gas flow measurement.

2. Scope

This standard applies to laboratory and field gas flow measurement for testing heating, ventilating, air-conditioning, and refrigerating systems and components. This standard is restricted to applications where the entire flow stream of gas enters and exits the gas flowmeter in a “gas-only” state during data recording with the following exceptions: 

a. This standard does not apply to airflow measurements at pressures within this range: -25 kPa to +25 kPa (-100 in. of water to +100 in. of water) referenced to ambient pressure. Those measurements are within the scope of ASHRAE Standard 41.2. 

b. This standard does not apply to fan performance rating airflow measurements. Those measurements are within the scope of ASHRAE Standard 51. 

c. This standard does not apply to gaseous-phase refrigerant mass flow measurements where the gas flow includes circulating lubricant. Those measurements are within the scope of ASHRAE Standard 41.10. 


Subcommittee 41.9-2018R, Standard Methods for Refrigerant Mass Flow Measurements Using Calorimeters

1. Purpose 

This standard prescribes methods for measuring mass flow rates for refrigerants and refrigerant/lubricant mixtures using calorimeters. 

2. Scope 

2.1 This standard applies to measuring mass flow rates for refrigerants and refrigerant/lubricant mixtures using calorimeters in laboratories. 

2.2 This standard applies where the entire flow stream of the refrigerant or the refrigerant/lubricant mixture enters the calorimeter as a subcooled liquid and leaves as a superheated vapor (evaporator type). 

2.3 This standard applies where the entire flow stream of the refrigerant or the refrigerant/lubricant mixture enters the calorimeter as a superheated vapor and leaves as a subcooled liquid (condenser type).
