FREQUENCY EFFECT ON TRANSFORMER OUTPUT (50/60 Hz)

A Transformer  Which one will give more Output? (operates on 50 or 60 Hz frequency?)

Which is mostly asked in an interview for Electrical Power Engineering Jobs.

For Example:

we will solve this using suppose values :

Let

When Transformer operates on 50 Hz Frequency Transformer =100kVA, R=7000, L=1.2 H, f= 60 Hz

We know = XL = √(2πfL)

A thermal wheel consists of a circular 
honeycomb matrix of heat-absorbing material, which is slowly rotated within the supply and exhaust air streams of an air-handling system.
Heat recovery systems are a great way to save energy, and money for building owners. It reduces energy bills by using the expelled air to heat (or cool) the incoming air, depending on the season (weather or climate). Most designs use a great invention known as the thermal wheel or the heat wheel to operate.

FAN COIL UNIT OR VERTICAL FAN COIL UNIT

A fan coil unit (FCU), OR a Vertical Fan Coil-Unit (VFC), is a device consisting of (1) heating and/or cooling heat exchange or 'coils' and (2) fan. It is part of an HVAC system found in residential, commercial, and industrial buildings. A fan coil unit using ductwork, and is used to control the temperature in the space where it is installed, or serve more then one spaces. It is controlled either by a manual on/off switch or by a thermostat or BMS, which controls the throughput of water to the heat exchanger using a control valve (actuator) and the fan speed.

AC Smells Bad

Does your air conditioning unit smell bad every time it turns on? If you are wondering what causes these bad odors

Their is following reasons .....
Dirty Evaporator CoilsIs you know that mold and mildew build up in the evaporator coil and can trigger that bad smell in your air conditioning unit?🤔 When dust or dirt combined with condensation (cold air) it breeds mold and bacteria into play. Signs of dirty evaporator coils include ice formation, weak air flow, evident buildup of mildew and more. You will need the help of the professionals to clean the evaporator coil because it sometimes requires disassembly.

FILTER TYPES PART 2

Heating or Cooling Elements

          Heating or Cooling Elements

AHU may need to provide heating, cooling, or both to change the supply air temperature, and humidity level depends on the location and the application. Such condition is provided by heat exchanger coils within the air handling unit air stream, such coils may be direct or indirect in relation to the medium providing the heating or cooling effect

FILTER TYPES

MERV measures a filter's arrestance ,a filter's ability to remove large airborne particles from the air , and dust-spot efficiency, its ability to remove small airborne particles , and assigns a number based on the filter's ability to remove the particles. Several types of air filters are common in commercial HVAC systems:

FIBERGLASS FILTER=This throwaway air filter is the most common type. Layered fiberglass fibers are laid over each other to form the filter media and typically are reinforced with a metal grating that supports the fiberglass to prevent failure and collapse.

POLYESTER AND PLEATED FILTERS= These filters are similar to fiberglass filters but typically have a higher resistance to airflow and a superior dust-stopping ability.

HIGH EFFICIENCY PARTICULATE ARRESTANCE (HEPA) FILTERS= These units filter the air passing through them at a very fine scale.

WASHABLE AIR FILTERS. These products are not as common and rely on the build-up of dust along the cloth to improve the efficiency of the filter. Industrial processes involving high volumes of coarse dust are typical applications.

AHU

An air handler or air handling unit (AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. An air handler is usually a large metal box containing a blower, heating, or cooling elements, filter or chambers, sound attenuators, and dampers. Air handlers usually connect to a ductwork ventilation system that distributes the conditioned air through the building and returns it to the AHU. Sometimes AHUs discharge (supply) and admit (return) air directly to and from the space served without ductwork.
