2.5 This normal is not relevant to All those collectors where the thermal storage device can be an integral Component of the collector to these an extent that the collection procedure and also the storage course of action can't be divided for the objective of making measurements of these two processes.
gas-fired drinking water heaters that has a remote temperature-activated Key working Handle and requiring circulation with the heater for heating (Variety III),
two.1 This conventional relates to heat-operated unitary air conditioners and warmth pumps consisting of one or more assemblies, including engine-pushed units. Exactly where these types of machines is provided in multiple assembly, the separate assemblies are intended to be employed alongside one another.
1. Goal: The objective of this standard is to ascertain a way of test to price the performance of a combination Room-heating and h2o-heating equipment.
2.one This regular applies to approaches for effectiveness tests single-phase and multi-stage optimistic displacement refrigerant compressors and condensing models that run at discharge pressures a lot less than the crucial pressure of your refrigerant. 2.2 This conventional applies to compressors and condensing models which possibly (a) do not need intermediate cooling or refrigerant injection, or (b) do have intermediate cooling or refrigerant injection and the power expected for intermediate cooling or refrigerant injection, if any, is A part of the calculated total input electricity towards the compressor or condensing unit.
The objective of this typical is to deliver procedures for analyzing the annual fuel utilization efficiency of household central furnaces and boilers.
This common won't apply to liquid-phase refrigerant mass flow measurements exactly where the liquid stream includes circulating lubricant. These measurements are within the scope of ASHRAE Normal 41.ten.
Objective: This regular prescribes strategies for refrigerant mass movement charge measurement in laboratory and subject apps utilizing flowmeters. Refrigerant mass stream rate measurements are demanded for air factory e-liquid compressor functionality tests and for tests other heating, ventilating, air-conditioning and refrigerating devices and factors.
2.three Ancillary gadgets are Commonly used to maneuver air to be dehumidified in the device and supply air flow for regeneration, but they are not an element of this typical.
one. Goal: To supply a normal laboratory take a look at process for assessing the general performance of free granular media Utilized in gas-period air cleansing devices.
two.four A check is considered to be in the scope of the regular if both a pre-examination uncertainty Examination plus a article-check uncertainty Examination generate satisfactory uncertainty limitations.
1. Objective: The goal of this normal will be to determine a check system to determine the development of insoluble resources in artificial lubricants and HFC systems.
prescribing computational suggests to empower reputable prediction of refrigerant vapor and liquid mass flow capability determined by the calculated circulation and gradient traits.
two. SCOPE: This typical applies to the following types of open up and closed business fridges and freezers used for exhibiting or holding foods for which refrigeration is possibly necessary or desired:
