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...
This standard applies to refrigerant pressure regulators that meet the definition found in Section 3 and that are intended for refrigerant service in applications where only single-phase flow occurs within the regulator. This standard is applicable to refrigerant pressure...
This standard applies to the measurement of the mass of a specific organic acid removed from a refrigerant-lubricant mixture by a liquid line filter drier containing an adsorbent desiccant material or through a specific adsorbent material that can remove acid by adsorption and/or chemical...
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...
Section 2 of Standard 62.2-2019 defines the scope of the standard. The section first describes the dwellings to which Standard 62.2 applies. The section then provides an overview of the content of Standard 62.2, which consists of the issues in dwelling units that affect IAQ. The section also...
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...
PURPOSE OF THIS MANUAL This manual was prepared to assist entry-level engineers in the design of heating, ventilating, and air-conditioning (HVAC) systems. It is also intended as a design guideline reference manual for the more experienced HVAC design engineer as well as a reference design manual...
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 guideline defines a standardized test apparatus and procedure for experimentally conducting fractionation analyses of refrigerant blends to determine the worst case of fractionation for flammability (WCFF) composition of refrigerant blends or to validate computer simulation...
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 c....
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...
