BSR/ASHRAE Standard 17-2015R, Method of Testing Capacity of Thermostatic Refrigerant Expansion Valves

PURPOSE: This standard prescribes a method of testing the capacity of thermostatic refrigerant expansion valves for use in vaporcompression refrigeration systems.

SCOPE:

• This standard is applicable to:

  • thermostatic expansion valves (also referred to in this standard as expansion valves) as defined in Section 3, “Definitions.”

  • expansion valves of the direct-acting type but not the pilot-operated type.

  • many currently used refrigerants deemed available and suitable according to ANSI/ASHRAE Standard 15, Safety Standard for Refrigeration Systems, and ANSI/ASHRAE Standard 34, Designation and Safety Classification of Refrigerants.

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

• This standard does not (a) specify tests for production, specification compliance, or field testing of expansion valves, nor (b) specify capacity rating conditions for testing expansion valves. These may be found in ARI Standard 750, Thermostatic Refrigerant Expansion Valves

BSR/ASHRAE Standard 35-2014R, Method of Testing Desiccants for Refrigerant Drying

PURPOSE: This standard establishes a method of testing desiccants for use in refrigerant drying.

SCOPE:

• This standard provides a method of testing desiccants only. For testing and rating driers, which use these desiccants, see ASHRAE Standard 63.1. (see Annex A, Informative Bibliography).

• The principle of this standard is to keep a desiccant of known water content in contact with the desired refrigerant until equilibrium has been established under known temperature conditions, after which the water content of the refrigerant is determined. This standard is applicable for all desiccants which do not react to the desired refrigerant.

BSR/ASHRAE Standard 79-2015R, Method of Testing for Fan-Coil Units

PURPOSE: The purpose of this standard is to prescribe laboratory methods of testing for fan-coil units to ensure uniform performance data for establishing ratings.

SCOPE: This standard includes procedures that:

• describe and specify test instruments and apparatus,

• describe and specify laboratory test methods and procedures,

• describe and specify test data to be recorded,

• describe and specify calculations to be made from test data,

• define terms used in testing

• specify standard thermodynamic properties.

BSR/ASHRAE Standard 130-2016R, Laboratory Methods of Test for Air Terminal Units

PUROSE: This standard specifies instrumentation, test installation methods, and procedures for measuring the capacity and related performance of constant volume, variable volume, and modulating integral diffuser air terminals.

SCOPE:

• The methods of test in this standard apply to air control devices used in air distribution systems. These devices provide control of air volume with or without temperature by one or more of the following means and may or may not include a fan:

  • Fixed or adjustable directional vanes (i.e. bypass terminal),

  • Pressure dependent volume dampers or valves (including air induction nozzles and dampers),

  • Pressure independent volume dampers or valves (including air induction nozzles and dampers),

  • Integral heat exchanger,

  • On/off fan control,

  • Variable speed fan control, and

  • Modulating integral diffuser terminals.

• This standard covers test methods for use in determining the following performance characteristics:

  • Sound power,

  • Temperature mixing and stratification,

  • Minimum operating pressure,

  • Air leakage,

  • Induced airflow,

  • Fan airflow,

  • Fan motor electrical power,

  • Condensation, and

  • Airflow sensor performance.

• This standard shall not be used for field testing.

BSR/ASHRAE Standard 133-2015R, Method of Testing Direct Evaporative Air Coolers

PURPOSE: This standard establishes a uniform method of laboratory testing for rating packaged and component direct evaporative air coolers.

SCOPE:

• The scope of this standard covers a method of testing for rating the saturation effectiveness, airflow rate, and total power of packaged and component direct-evaporative air coolers.

• Covered tests also include methods for measuring static pressure differential of the direct evaporative air cooler, density of the air, and speed of rotation of the fan.

• This standard requires that packaged and component direct evaporative air coolers are simultaneously tested for airflow, total power, and saturation effectiveness.

• The ratings resulting from application of this standard are intended for use by manufacturers, specifiers, installers, and users of evaporative air cooling apparatus for residential, commercial, agricultural and industrial ventilation; air cooling applications; and for commercial, industrial, and agricultural processing applications.

BSR/ASHRAE Standard 143-2015R, Method of Testing for Rating Indirect Evaporative Coolers

PURPOSE: This standard provides test procedures and calculations for establishing the cooling capacities and power requirements for indirect evaporative cooling equipment.

SCOPE:

• This standard covers testing under steady-state conditions
  for rating of indirect evaporative coolers that:

  • sensibly cool a primary airstream through heat exchanger(s) by the evaporation of water into a secondary airstream, and

  • are self-contained or are components of packaged systems.

• This standard does not cover:

  • devices that use mechanical refrigeration or thermal storage to cool the primary airstream, the secondary airstream or the water provided for evaporation, or

  • devices that dry the primary or secondary airstream.

BSR/ASHRAE Standard 152-2014R, Method of Test for Determining the Design and Seasonal Efficiencies of Residential Thermal Distribution Systems

PURPOSE: This standard prescribes a method of test to determine the efficiency of space heating and/or cooling thermal distribution systems under seasonal and design conditions. The objective is to facilitate annual energy calculations and heating and cooling equipment capacity calculations.

SCOPE:

• This standard applies to single-family detached and attached residences with independent thermal systems.

• This standard applies to air, hydronic, refrigerant and electric distribution systems.

BSR/ASHRAE Standard 153-2015R, Method of Test for Mass Flow Capacity of Four-Way Refrigerant Reversing Valves

PURPOSE: To provide a test method for measuring the refrigerant vapor mass flow capacity of four-way refrigerant reversing valves with sufficient accuracy to facilitate application decisions.

SCOPE: This standard describes test methods, procedures, instrumentation, computations, and suggested apparatus for this test.

BSR/ASHRAE Standard 193-2010 (RA 2014)R, Method of Test for Determining Airtightness of HVAC Equipment

PURPOSE: This standard prescribes a method of test to determine the airtightness of forced-air HVAC equipment prior to field installation.

SCOPE:

• This standard applies to the following:

  • Equipment intended for installation in ducted systems, including furnaces, heat pumps, air conditioners, coil boxes, filter boxes, and associated components.

  • Equipment that moves less than 3000 cfm (1400 L/s) of air.

• It does not apply to field installed components, such as
  plenums or ducts.
