ASHRAE 190-2020 covers the Method of Testing for Rating Indoor Pool Dehumidifiers, giving buyers a clear technical reference for evaluating equipment used to control humidity in indoor aquatic spaces. As an ASHRAE standard, ASHRAE 190-2020 supports consistent test methods and rating comparisons for dehumidifiers serving natatoriums and similar facilities where moisture control is critical. It is useful for professionals who need a recognized basis for specification review, product comparison, or compliance-focused documentation in HVAC and building systems work.

Purpose of ASHRAE 190-2020

The purpose of ASHRAE 190-2020 is to provide a standardized method for testing and rating indoor pool dehumidifiers. In practical terms, it serves as a recognized technical benchmark that helps align manufacturers, specifiers, and reviewers around a common performance evaluation approach. For buyers, this matters because rating consistency makes it easier to compare equipment, support procurement decisions, and document expected performance for indoor pool environments. The standard is especially relevant where humidity control, corrosion risk, and occupant comfort must be considered together.

How ASHRAE 190-2020 is used

ASHRAE 190-2020 is typically used by HVAC engineers, commissioning teams, consultants, and facility managers involved with indoor pools, aquatic centers, recreation facilities, and other humid spaces that rely on dehumidification. It may support equipment submittal review, product selection, testing oversight, and technical documentation during design or retrofit work. Procurement and QA/QC teams may also use it when comparing manufacturer claims or verifying that rated performance is based on a recognized method. In these workflows, the standard helps keep evaluation criteria consistent across projects and suppliers.

Why ASHRAE 190-2020 matters in practice

ASHRAE 190-2020 matters because indoor pool dehumidifiers play a direct role in protecting building materials, supporting occupant comfort, and maintaining stable operating conditions. A defined test method helps reduce ambiguity when comparing products or reviewing performance data, which is valuable for engineering reference, commissioning support, and facility planning. For teams responsible for aquatic facilities, it can improve documentation quality and reduce the risk of selecting equipment based on inconsistent or non-comparable ratings. ASHRAE 190-2020 also helps create a clearer basis for technical decisions during new design or replacement projects.
