two. SCOPE: This typical relates to electronic and/or pneumatic Management programs employed for tension unbiased airflow control in terminal units for VAV and CV air relocating methods.
two.1 This conventional applies to heat-operated unitary air conditioners and heat pumps consisting of one or more assemblies, together with engine-driven devices. Wherever this kind of machines is delivered in multiple assembly, the independent assemblies are intended to be employed jointly.
1 This normal is meant to foster a commonality in deciding and reporting the Electricity efficiency of properties to aid a comparison of design and style techniques and/or Procedure advancements in buildings in addition to the event of making Power performance standards and reporting of eco-friendly household gas emissions linked to building Procedure.
two.2 This protocol types each constructing automation and Handle Laptop as a group of data constructions identified as 'objects,' the properties of which stand for different components of the hardware, application, and Procedure with the unit.
Function: The goal of this guideline is always to advocate uniform take a look at techniques and methods for experimentally analyzing the fractionated (vapor and liquid) compositions of refrigerant blends underneath simulated leakage from containers and tools in storage, transportation, operation and service. A fractionation Assessment is carried out to determine the worst scenario fractionated formulation (WCFF) of a refrigerant Mix for assigning flammability and toxicity protection classifications below requirements established in ANSI/ASHRAE Typical 34.
