HVAC

ASHRAE tool allows the user to find the nearest weather station of interest and related climatic design conditions.

ASHRAE Dayton Chapter developed this online tool to calculate typical psychrometric state point properties.

This database by ASHRAE contains the service life data for all major pieces of HVAC equipment.

This online tool is a comprehensive glossary of terms related to the built environment with a focus on HVAC&R.

Calculates friction loss for flexible and sheet metal duct. Also, it calculates equivalent rectangular duct and more.

Calculates the steam distribution main pipe size based on pressure drop and velocity methods.

Calculates the steam trap discharge line size based on condensate and flash steam flow.

Sizes the pump discharge line from a condensate pump to the downstream condensate system.

This tool calculates flowrate, valve flow coefficient and pressure drop for saturated steam applications.

This tool calculates flowrate, valve flow coefficient and pressure drop for sub-saturated water applications.

Calculates steam humidification load based on a fixed quantity of outside air intake.

Converts the steam flowrate to any heat exchanger to the corresponding heat transfer rate.

This tool calculates the percentage flow and actual flow of cold and hot water streams.

Converts any heat exchanger's heat rating to the corresponding steam flowrate.

This is a conversion tool that allows unit values of different properties to be compared.
