This analysis provides a comparison of the testing of Radioisotope Thermoelectric Generators (RTGs) and RTG components with the testing requirements of ANSI N (R) ``Sealed Radioactive Sources, Categorization``. The purpose of this comparison is to demonstrate that the RTGs meet or exceed the requirements of the ANSI standard, and thus can be excluded from the Author: C.O. Grigsby.

Neither of these standards attempt to account for seasonal variations. Standard ARI ratings are intended for direct exchange ground-source heat pumps. ASHRAE transitioned to ISO in , which replaces ARI , and The new ISO standard produces slightly higher ratings because it no longer budgets any electricity for water. Yes Rahul the potency of your API can be given above % compared to the standard. We can take the potency of the standard = % and then compare your API's potency against the standard.

Abstract This investigation compares the ARI () and the ISO () heating and cooling standards for water-source heat pumps to determine the difference in capacity and efficiency for a given heat pump tested with these standards.
Multiple tests were run using two heat pumps of different capacities from different : W Vance Payne, Piotr A Domanski.
This investigation compares performance ratings obtained when testing water-source heat pumps using the Air-conditioning and Refrigeration Institute (ARI) Standard and the International Standards Organization (ISO) Standard 1. Multiple tests were run using two heat pumps of different capacities from different manufacturers.
These tests included a. the rating obtained for water-source heat pumps tested using two standards: the standard developed by the Air-Conditioning and Refrigeration Institute (ARI), ARI Standard (), and the standard developed by the International Organization for Standardization (ISO), ISO Standard ().
On January 1,the ARI adopted the. A comparison of rating water-source heat pumps using ARI standard and ISO standard [microform] / W. Vance Payne, Piotr A. Domanski U.S. Dept. of Commerce, Technology Administration, National Institute of Standards and Technology Gaithersburg, MD.

However, ISO pumps can’t be used as direct substitutes for ANSI B machines without some adaptations to the mounting plates and motor couplings.

Water-Source Heat Pump. A water-source heat pump is typically one of multiple units using fluid circulated in a common piping loop as a heat source/heat sink. The temperature of the loop fluid is usually mechanically controlled within a moderate temperature range of 60 F to 90 F [ C to C].
The heat pump consists of one orFile Size: 84KB.

The performance standard AHRI/ASHRAE/ISO became effective January 1, and replaces AHRI Standards, and This new standard has three major categories: Water Loop (comparable to ARI ), Ground Water (ARI ), and Ground Loop (ARI ).
Although these standards are similar there are some differences. This standard does not apply to testing and rating of heat pumps or water heaters covered in ANSI/AHRI/ASHRAE ISO Standard & 2, AHRI Standard or ANSI/AHRI Standard This standard does not apply to testing and rating of Air-Cooled or Water Cooled Heat Reclaim Condensers covered in AHRI Standard /File Size: KB.
AHRI Standard is the only standard that reports sound pressure levels. This standard was originally written to define a method of measuring the sound pressure level in equipment rooms, where the risk of hearing loss was the primary concern.
Over time, this standard became the de facto standard for rating water-cooled chiller sound. This part of ISO establishes performance testing and rating criteria for factory-made residential, commercial and industrial, electrically driven, mechanical-compression type, water-to-water and brine-to-water heat pumps.
The requirements for testing and rating contained in this part of ISO are based on the use of matched assemblies. ISOWater-source heat pumps -- Testing and rating for performance -- Part 1: Water-to-air and brine-to-air heat pumps by ISO TC 86/SC 6 (Author) ISBN.
