Day (24): Heating, Ventilation and Air Conditioning Session 7

Session Title: Fans 🌬🌬🌬

Session Outline: Types of Fans and their application part 1

Exhaust fans: are used to pull excess
moisture and unwanted odors out of a particular room or area. They are commonly found in bathrooms and kitchens, where moisture can build up due to activities such as showering, washing, or cooking.

Smoke Spill fans: are used for Car Park Ventilation system in case of fire when the polluted air needs to be ventilated outside with the help of Jet Fans. These fans are placed on the ramp opening to the environment which extracts smoke and releases it in the environment.

Jet Fans: support the natural flow between the supply-air and extract-air zones. They provide motion in regions with low air speeds, thus guaranteeing the daily ventilation requirements for all areas.

Day (23): Low Current systems Session 7

Session Title: Fire Alarm control panels🚨🚨

Session Outline: Difference between addressable and conventional fire Alarm control panel

With an addressable system, Every device connected to the addressable system has its own unique address. When a fire is detected, the device’s address shows up on the main control panel, telling you exactly which device has been activated. This will enable you to find the exact location of a fire and extinguish them quickly.🔥🔥
With a conventional system, there is no way of pinpointing the exact location of the fire. However, by wiring your building into different zones, you can get a general idea of where the fire is. For instance, if you have two floors, you could wire the first as ‘zone 1’ and the second as zone 2. So if a fire occurs in zone 1, you know that the fire is somewhere on the first floor.

Day (22): Photovoltaic systems Session 🌅🌅🌅

Session Title: Solar Angles Part 2

Session Outline: Definitions of solar angles

Hour Angle, ω: This is based on the sun's angular displacement, east or west, of the local meridian (the line the local time zone is based on). The earth rotates 15º per hour so at 11am, the hour angle is -15º and at 1pm it is 15º.

Surface Azimuth Angle, γ: This is the angle between the line that points straight out of a PV panel and south. It is only measured in the horizontal plane. Again, east is negative and west is positive. If a panel pointed directly south, this angle would be 0º.

Collector Slope, β: This is the angle between the plane of the solar collector and the horizontal. If a panel is lying flat, then it is 0º. As you tip it up, this angle increases. It does not matter which direction the panel faces.

Day (21): Electrical Distribution System Basics
Session Title: Voltage Transformers Part 2

Session Outline: Connection of voltage transformer and the ratio error.

**Connection of Potential Transformer

The potential transformer is connected in parallel with the circuit. The primary windings of the potential transformer are directly connected to the power circuit whose voltage is to be measured. The secondary terminals of the potential transformer are connected to the measuring instrument like the voltmeter, wattmeter, etc.The secondary windings of the potential transformer are magnetically coupled through the magnetic circuit of the primary windings.

The primary terminal of the transformer is rated for 400V to several thousand volts, and the secondary terminal is always rated for 400V. The ratio of the primary voltage to the secondary voltage is termed as transformation ratio or turn ratio.

**Ratio and Phase Angle Errors of Potential Transformer

In an ideal potential transformer, the primary and the secondary voltage is exactly proportional to the primary voltage and exactly in phase opposition. But this cannot be achieved practically due to the primary and secondary voltage drops. Thus, both the primary and secondary voltage is introduced in the system.

Voltage Ratio Error – The voltage ratio error is expressed in regarding measured voltage.

Phase Angle Error – The phase angle error is the error between the secondary terminal voltage which is exactly in phase opposition with the primary terminal voltage.

The increases in the number of instruments in the relay connected to the secondary of the potential transformer will increase the errors in the potential transformers.

Day (21): Heating Ventilation and Air Conditioning systems Session 6

Session Title: Basic Definitions part 1

Session Outline: HVAC systems basic definitions and their differences

The furnace. The furnace takes up a majority of the space in an HVAC system. It’s usually in the basement, and it’s an important component. The furnace moves air from the heat exchanger into the air ducts. The furnace is usually confused with boilers, but they’re different HVAC appliances

The heat exchanger. The heat exchanger is not part of the furnace. It’s located inside the furnace, but the heat exchanger has its own capabilities. It adds heat to the incoming air from the combustion chamber.

The evaporator coil. This HVAC part is also in the furnace, but handles a different job. Refrigerant (a fluid that causes cooling) runs through the evaporator coil. The coil absorbs heat from air passing over it. The now-cold air blows through the air ducts throughout your home.
