ASHRAE Standards Every HVAC Professional Should Know!

Whether you're designing HVAC systems, analyzing indoor air quality, or working on building energy efficiency, ASHRAE standards are the backbone of our industry. Here are the key ones to keep in mind:

Ventilation & IAQ

ASHRAE 62.1 - Ventilation for commercial buildings

ASHRAE 62.2 - Ventilation for residential buildings

ASHRAE 55 - Thermal comfort for human occupancy

ASHRAE 52.2 - Air filter performance (MERV ratings)

Energy & Efficiency

ASHRAE 90.1 - Energy standard for commercial buildings

ASHRAE 90.2 - Energy-efficient design for residential

ASHRAE 100 - Energy efficiency in existing buildings

* Refrigeration & Safety

ASHRAE 15 - Safety standard for refrigeration systems

ASHRAE 34 - Refrigerant classification & safety Water Systems & Health

ASHRAE 160 - Moisture control in buildings

ASHRAE 188 - Legionella risk management

ASHRAE 170 - Ventilation for healthcare facilities Labs, Controls & Commissioning

ASHRAE 110- Laboratory fume hood testing

ASHRAE 135 (BACnet) - Building automation & communication

ASHRAE 202 - Commissioning of building systems

* Mastering these standards helps you design safer, smarter, and more energy-efficient buildings.

Let's keep learning and building a better HVAC community!

Reciprocating Compressor‼️⚙️✅👇🏼

An overview of compressors, particularly focusing on reciprocating compressors which operate by drawing gas into a cylinder, compressing it, and discharging it.

It describes the types of reciprocating compressors (single and double acting), their components, and the principles of their operation. Additionally, it highlights the applications of these compressors in industries such as PET bottling and gas filling stations.

Types of spark plugs: ⚙️‼️✅👇🏼

1. *Copper* – standard, good conductivity, cheaper, needs frequent replacement.
2. *Platinum* – has a platinum tip for longer life and better performance than copper.
3. *Iridium* – uses iridium for a finer electrode, giving the longest life and best efficiency.
4. *Double* (Double Platinum) – features two platinum electrodes for extended durability.
5. *Triple* (Triple Platinum) – has three platinum electrodes for even longer life and smoother firing.
6. *4 Electrodes* – four ground electrodes provide multiple spark paths for stable ignition.
