This standard applies to the measurement of the mass of a specific organic acid removed from a refrigerant-lubrican
This standard applies to FDD systems that are intended to detect or diagnose faults that affect the performance of air economizers of air-conditioning equipment. This standard defines laboratory tests for faults in four categories of economizer function: sensor communication, actuator...
This standard applies to a. absorption packages used to chill and/or heat water, as defined in Section 3, and b. testing that will occur where proper instrumentation and load stability can be provided. It is not the intent of this standard to provide for testing in typical field installations,...
This standard provides a comprehensive set of procedures for micro combined heat and power devices whose maximum net electrical power output is less than 50 kW and whose maximum useful thermal power output is less than 300 kW. The maximum allowable ratio of thermal power output (exclusive of any...
This standard applies to indoor pool dehumidifiers using electrically driven, mechanical vapor-compression refrigeration systems consisting of one or more factory-made assemblies that dehumidify and circulate air and may include pool water heating, air reheating, cooling, filtering, and heat...
This standard a. defines performance scoring methods for cooling and heating system delivered capacity and cooling system efficiency; b. establishes uniform methods of measurements and testing procedures for airflow, temperature, enthalpy, and power; c. specifies test instruments, specifications,...
This standard shall be used to determine the structural strength, dimensional stability, durability, and leakage characteristics of HVAC air ducts. This standard does not address the following: a. Fittings b. Effects of aerosols, solid particulates, corrosive environments, or combustibility...
FOREWORD As the tall building industry moves into a new decade, it is appropriate to stand back and take stock of what we've accomplished, but also to be honest about where we have fallen short. The foreword to the first edition of this book, published in 2015, highlighted the critical issues of...
The environmental factors addressed in this standard are temperature, thermal radiation, humidity, and air speed; the personal factors are those of activity and clothing. It is intended that all of the criteria in this standard be applied together, as comfort in the indoor environment is complex...
This standard includes the following types of liquid-chilling systems. These system types are further described in Section 5, "Equipment Types." Vapor compression cycle. Absorption cycle. This standard does not include systems with a net refrigeration capacity less than 10 tonR (35 kW). This...
This standard applies to enclosed transportation facilities consisting of road tunnels, railway tunnels, mass transit tunnels, and mass transit stations. This standard provides criteria for non-emergency ventilation. This standard addresses the design, construction, testing, commissioning,...
This standard applies to power measurements under laboratory and field conditions when testing heating, ventilating, air-conditioning, and refrigerating systems and components. PURPOSE This standard prescribes methods for power measurements.
Preface The ASHRAE Historical Committee proposed compiling biographical information on men and women who had made substantive contributions to the art and science of the industry ASHRAE serves. The project, part of the celebration of ASHRAE's 125th anniversary, received many...
This standard provides methods of testing for heating capacity and energy efficiency. This standard applies to forced circulation heaters operated by gas, oil, and/or electricity- including heat pumps using ambient air, earth, water, or a brine solution as a heat source-and hybrid heaters. PURPOSE...
