two.5 This normal will not prescribe certain ventilation charge prerequisites for spaces that incorporate cigarette smoking or that don't meet up with the necessities inside the common for separation from Areas that contain smoking cigarettes.
one. Intent: This standard specifies instrumentation and facilities, check set up approaches, and processes for deciding the accuracy and stability of airflow Command units for terminal units at various airflow established points.
Specifies check instruments, specs and calibration prerequisites for executing these measurements and assessments;
one. Function: The objective of this guideline is to offer tips for creating specs for making automation devices in heating, ventilating, and air-conditioning (HVAC) Manage purposes, and recommendations for specifying The mixing of other creating systems right into a making automation program.
one. Intent: The goal of this typical is to deliver exam methods for determining the cooling ability of unitary air-conditioning gear along with the cooling or heating capacities, or both equally, of unitary warmth pump tools.
one. PURPOSE: This standard prescribes methods of tests the thermal overall performance and liquid-side tension fall of liquid cooled refrigerant condensers.
two.1 This regular prescribes a little-scale laboratory exam approach for measuring the contaminant removing efficiency of free granular sorptive media used in gasoline-section air cleaning products as mounted (in a very check equipment) in an airstream and challenged with examination gases under continual-point out problems.
The use of steel vessels will permit for your tests of a number of resources, regulating the pressure of your check, utilization of a realistic sample measurement to oil/refrigerant ratio along with other analytical tests, such as extraction.
Outlines strategies for Net-based mostly management of Use Cases to aid progress of official info definitions and implementation in HVAC&R field software package.
2.two Usually, tools within this typical would consist of one or more desiccant Speak to stations through which the air for being dehumidified is moved, a method to show the dampness-laden desiccant to some source of heat Vitality for regeneration, and also a heating unit.
two. SCOPE: This guideline covers the processes, formats, and strategies essential for analysis and documentation from the general performance of equipment and programs that control HVAC&R methods.
