Standard for Performance Rating of Indoor Pool Dehumidifiers

ARI 910: Standard for Performance Rating of Indoor Pool Dehumidifiers

For engineers and designers tasked with maintaining optimal environmental conditions in indoor aquatic facilities, understanding and applying a robust performance rating standard is essential. ARI 910 provides the authoritative framework for evaluating the capabilities of indoor pool dehumidifiers, ensuring consistent performance and facilitating informed equipment selection. This industry-leading standard offers a proven methodology for comparing diverse units, ultimately contributing to energy efficiency and occupant comfort.

What is ARI 910?

ARI 910, developed by the Air-Conditioning and Refrigeration Institute (ARI), is a comprehensive standard specifically designed for the performance rating of indoor pool dehumidifiers. Its primary purpose is to establish standardized definitions, test procedures, and rating criteria for these specialized HVAC units. This ensures that manufacturers and specifiers can rely on consistent, comparable performance data for electrically operated, vapor-compression refrigeration systems used in indoor pool environments.

Scope & Purpose

This standard governs the performance rating and testing of factory-made, electrically operated, vapor-compression refrigeration systems intended for use as indoor pool dehumidifiers. This includes units that provide dehumidifying, air circulation, and air reheating functions, and may optionally include cooling, air cleaning, pool water heating, and heat recovery. ARI 910 explicitly excludes the rating and testing of individual component assemblies intended for separate use, focusing solely on the performance of the complete dehumidifier system.

Who Must Comply?

• • Primary audience: HVAC Engineers, Product Engineers, Test Technicians, Building Managers, and Facility Engineers.
• • Industries affected: HVAC Manufacturing, Pool and Spa Services, Commercial Construction, Hospitality, and Recreation.
• • Compliance nature: While ARI standards are often voluntary, compliance is strongly recommended for accurate product comparison and to meet industry best practices. Manufacturers seeking to publish performance ratings in accordance with the standard must adhere to its provisions.
• • Enforcement: Compliance is typically self-certified by manufacturers based on testing performed according to the standard. Third-party verification may be sought by specifiers or building owners.

Key Requirements Overview

The standard requires manufacturers to define and adhere to specific test conditions for evaluating dehumidifier performance. Key provisions include establishing standardized methods for measuring moisture removal capacity (MRC) and moisture removal efficiency (MRE), crucial metrics for indoor pool applications. Professionals must ensure that published ratings, which include data on capacity, efficiency, and operating parameters, are presented clearly and consistently for all units of a similar type. The standard also outlines minimum data requirements for published ratings and specifies marking and nameplate data to facilitate proper identification and application.

Related Standards & References

ARI 910 often works in conjunction with other engineering standards. For example, definitions related to air conditioning and refrigeration terminology are typically harmonized with ASHRAE standards. Furthermore, testing procedures may reference or be supplemented by specific test method standards, ensuring a complete and rigorous evaluation of the equipment's performance in its intended application.
