ASHRAE 164.1-2008 PDF

This standard provides rules for the testing of central system humidifiers for residential applications. Its purpose is to provide a uniform method for testing in a laboratory environment. Although the method of test originated in ARI Standard 610, Performance Rating of Central System Humidifiers, the project committee has developed this separate method of test to be used independently of the Air Conditioning & Refrigeration Institute (ARI) rating standard so that manufacturers, specifiers, installers, and users of central system residential humidifiers can test a humidifier''s capacity under a variety of conditions with uniform results. This method of test was prepared in cooperation with ARI to utilize with ARI Standard 610.

The scope of this standard covers a method of test for the humidification rate of central-system residential humidifiers intended for use with forced warm air heating and/or cooling systems. This method of test describes the test apparatus, conduct of the test, and information to be recorded. Tests covered include methods for measuring electrical power input, water flow rate, water temperature, and water pressure to the test humidifier. Also included are airflow rate, static pressure, temperature, and relative humidity entering and maintained by the test apparatus. Information resulting from the application of this method of test is intended for use by manufacturers, specifiers, installers, and users of central-system residential humidifiers. This method of test does not apply to self-contained humidifiers, portable humidifiers, or humidifiers for commercial and industrial applications.
