Variable-Geometry Supply Diffusers
Variable-geometry supply diffusers can be used to ensure adequate air movement when the supply volume is low.
Duct Calculator
This duct calculator allows three different calculations to be carried out quickly and with ease. These calculations are divided in four areas
Variable Air Volume System
Variable air volume (commonly known as VAV) cooling is an all-air system which can satisfy the individual cooling requirements of multiple zones, typically within office buildings. This is achieved by supplying air at a constant temperature from a central plant to one or more VAV terminal units in each zone.
Constant Volume Systems
Constant volume cooling is a simple system often used to provide tempered fresh air in multi-zone buildings containing partially centralised air/water systems (such as a fan coil installation).
Making Air-Duct Calculators
Air-duct calculators are very useful tools to use when sizing duct

These clinics are comprehensive and detailed courses used to educate on the fundamentals heating, ventilating, and air conditioning (HVAC). Each clinic includes a student workbook, with corresponding quiz questions/problems.
Types Of Cooling Systems
The most common types of cooling system can been classified as centralized or partially centralized air/water systems, or local systems.
Carrier Technical Development Programs (Tdp) Books
Technical Development Programs (TDP) are modules of technical training on HVAC theory, system design, equipment selection and application topics. They are targeted at engineers and designers who wish to develop their knowledge in this field to effectively design, specify, sell or apply HVAC equipment in commercial applications.

Hvacr Equipment Life Expectancy
Below you can see ASHRAE chart of HVAC Equipment Life Expectancy. The chart includes a list of median life expectancy for the following types of equipment:
Air Filters Efficiency Classification
ASHRAE 52.2: Filter testing was originated from America in 1930 (ASHVE and AFI code). It was then reviewed and modified in 1967 and 1968. ASRHAE collaborated with American National Standard Institude (ANSI) in 1992 to create ASHRAE-ANSI 52.1. Finally updated to ASHRAE 52.2 in 2007.

Constant Volume Air Handling
Shows the general arrangement for the four-channel control of an air handling system serving one zone in which the four channels control, in sequence, heating → heat recovery → fresh air (‘free’ cooling) → chilled water-based cooling.
Solar Rotation
Solar rotation is able to vary with latitude because the Sun is composed of a gaseous plasma. The rate of rotation is observed to be fastest at the equator (latitude φ=0 deg), and to decrease as latitude increases. The differential rotation rate is usually described by the equation shown.

Infiltration Rules Of Thumb
The infiltration rate is the volumetric flow rate of outside air into a building, typically in cubic feet per minute (CFM) or liters per second (LPS). The air exchange rate, (I), is the number of interior volume air changes that occur per hour, and has units of 1/h.
