Pumps and Fans	In order to move a mass (solids, liquids or gases) you have to apply an external force (energy). Fluids (gases and liquids) can be made to move from say point-A to point-B by creating...
Refrigeration	Cooling uses refrigeration which is accomplished using substances that have very low boiling points. For example Ammonia (NH4) at standard atmospheric temperature (say between 60oF and...
Time Value of Money	Symbols for Interest Formulas: N Number of time periods (typically years but it could be months) i Interest rate (fixed) over the time period P Present Value ( Worth / Sum /...
Lighting (NASA)	Light consists of electro-magnetic waves. It is the segment of the electro-magnetic spectrum of radiant energy that lets us see. All radiant energy consists of electro-magnetic waves...
Duct Sizing Charts & Tables	Carrier Air-Conditioning Manual(1960-?) TABLE 6 - CIRCULAR EQUIVALENT DIAMETER,* EQUIVALENT AREA AND DUCT CLASS OF RECTANGULAR DUCTS FOR EQUAL FRICTION TABLE 6 - CIRCULAR EQUIVALENT...
Pipe Sizing Charts Tables	CLOSED SYSTEMS Design Criteria: 3' Frictional Pressure Drop per 100' Pipe Length with a Maximum Velocity of 10 ft/sec Figure - 1 Friction Loss for...
BOILERS	Syllabus Boilers: Types, Combustion in boilers, Performances evaluation, Analysis of losses, Feed water treatment, Blow down, Energy conservation opportunities. 2.1 Introduction A...
Centrifugal Chiller - Fundamentals	NOTICE The information contained within this document represents the opinions and suggestions of McQuay International. Equipment and the application of the equipment and system...
Facilities Management	No matter how thorough and forward thinking your energy-model may be, it’s well known that the inhabitants of any building invariably affect its energy usage and savings. We’ve all...
HEATING AND COOLING SYSTEM UPGRADES	Overview Heating and cooling systems are the largest single consumers of energy in buildings. These systems condition the air within a building so that occupants are comfortable....
HVAC: Centrifugal Chillers	Does your building have a centrifugal chiller? If it does, you should know that chillers typically consume more electricity than any other single energy-consuming device in a...
Chiller Plant Design	Introduction Using chilled water to cool a building or process is efficient and flexible. A two-inch Schedule 40 pipe of chilled water can supply as much comfort cooling as 42"...
PV Modeling in eQUEST	I'd like to summarize all the responses and my findings about PV modeling in eQuest. Specially thank Scott Criswell for pointing me to the right directions on this simulation skill....
Introduction to Photovoltaic Systems	HIGHLIGHTS ♦ The energy needs of a typical home in Texas could be met by covering only half of its roof with solar electric panels. ♦ Photovoltaic (PV) cells convert...
How Solar Electric Technology Works	Image above shows a residential Grid-Connected Photovoltaic System. 1. solar panels 2. inverter 3. breaker box 4. home power and appliances 5. meter 6. utility power grid. (1) Solar...
Basic Photovoltaic Principles and Methods	Notice This publication was prepared under a contract to the United States Government. Neither the United States nor the United States Department of Energy, nor any of their employees...
Photovoltaic (PV) Tutorial	This presentation was designed to provide Million Solar Roof partners, and others a background on PV and inverter technology. Many of these slides were produced at the Florida Solar...
Clone of Pumps and Fans	In order to move a mass (solids, liquids or gases) you have to apply an external force (energy). Fluids (gases and liquids) can be made to move from say point-A to point-B by creating...
