TIPS AND TUTORIALS FOR ENERGY SAVING IN AIR CONDITIONING SYSTEMS

Heating/Ventilation/Air Conditioning Systems Energy Saving Tips
 
Majority of our electricity consumption are alloted to our conditioning units. Continuous maintenance of this device is necessary to ensure its effectivity and efficiency. This is a guide to follow for you to keep your airconditiong system function reliably. An unmaintained airconditiong system usually consumes more electrical energy compared to that of a well-maintained one.

 
Regularly...
  • Keep vents closed in unoccupied areas to preventheating or cooling of storage areas and closets.
  • Reduce fresh air intake to the minimum necessary forthe type of business.
  • Treat water in evaporative condensers regularly.
  • Replace resistance electric heating systems with heatpumps.
  • Replace old HVAC systems with new energy-efficientsystems.
  • Install paddle fans, stratotherm fans, or other recirculatingsystems to create air movement. Ceiling temperatures can often be 30° to 40° higher than floortemperatures, and air movement from fans can enhance thecooling ability of air conditioning systems.
  • Install air conditioner economizers to use outside air tocool buildings when outdoor air is lower than indoor temperatures.
  • Install time clocks, set-back thermostats, andmicroprocessor thermostats to monitor HVAC systems whenbuildings are unoccupied.
  • Install intermittent ignition devices on natural gasfurnaces to save natural gas.
  • Modify flue dampers on natural gas furnaces toincrease burner efficiency.
 
Monthly ...
  • Check air filters monthly, and clean or change asneeded.
  • Check air intake screens monthly, and clean asrequired.
  • Inspect air dampers monthly, and keep them as airtightas possible.
  • Check V-belts (fan belts) monthly for frays, cracks, andnicks, and replace as necessary.
  • Check heat recovery devices monthly for properoperation.
  • Brush off air conditioner condenser coils monthly.Quarterly ...
  • Check motors, bearings, and blower fans every threemonths, and lubricate as required.
  • Check heating and cooling coils every three months,and clean as needed.
  • Check vacuum blower compartments every threemonths.
  • Check ducts, vents, and pipes every three months, andrepair any damaged insulation.
 
Seasonally ...
  • Check cooling systems in the spring before the coolingseason begins.
  • Check pulleys and sheaves in the spring and fall foralignment and proper belt tension.
  • Set thermostats at 78°F or higher for cooling during thesummer.
  • During the summer, open windows and use only thefan portion of cooling systems when outdoor air is coolerthan indoor temperatures.
  • Keep doors and windows closed when air conditioningsystems are operating.
  • Check heating systems in the fall before the heatingseason begins.
  • During the winter, open shades and blinds on sunnydays to warm buildings naturally, and close them at night toprevent heat loss.
  • Set thermostats at 68°F degrees or lower for heating inthe winter, and 55°F when buildings are unoccupied. Ifheating is required in warehouses, set thermostats to 50°F .
Annually ...
  • Check cabinets and brackets once a year, and tightenall bolts and screws as necessary.
  • Check housings yearly, and remove rust and repaint asrequired.

PARTS OF A POWER TRANSFORMER

What are the name of the basic parts of a Power Transformer? We can not deny the fact that only a handful of electrical engineering students are presently familiar with power transformers especially on what it looks like. Unlike a transformer we found in our homes, a power transformer’s appearance and construction is somewhat more complicated. It is not just a simple winding with a primary and secondary terminal although basically any transformer has one. The function that a power transformer plays in an electrical system is very important that an electric utility can not afford to loss it during its operation. Our discussion here will focus more on the basic parts and functions of a power transformer that are usually tangible whenever you go to a substation . Although not all power transformers are identical, nonetheless they all have the following listed parts in which the way of construction may differ.

ELECTRIC MOTOR FRAME SIZE STANDARD SPECIFICATIONS

ELECTRIC MOTOR FRAME SIZE STANDARD SPECIFICATIONS How is electric motor frame size being specified? Motor frame dimensions have been standardized with a uniform frame size numbering system. This system was developed by NEMA and specific frame sizes have been assigned to standard motor ratings based on enclosure, horsepower and speed. The current standardized frames for integral horsepower induction motors ranges from 143T to 445T. These standards cover most motors in the range of one through two hundred horsepower. Typical example of where you can locate the frame is shown in Fig 1.2.D – Frame No. The numbers used to designate frame sizes have specific meanings based on the physical size of the motor. Some digits are related to the motor shaft height and the remaining digit or digits relate to the length of the motor. The rerate, or frame size reduction programs were brought about by advancements in motor technology relating mainly to higher temperature ratings of insulating mate...

ELECTRIC MOTOR NAMEPLATE SPECIFICATIONS

How do we interpret an electric motor nameplate? Motor standards are established on a country by country basis.Fortunately though, the standards can be grouped into two major categories: NEMA and IEC (and its derivatives). In North America, the National Electric Manufacturers Association (NEMA) sets motor standards, including what should go on the nameplate (NEMA Standard MG 1-10.40 "Nameplate Marking for Medium Single-Phase and Polyphase Induction Motors").
