Building Automation: Slicing the pie...

It's Summer!

Building automation: Every piece of equipment works as a heart or brain. Similar to the giant Pacific octopus which has three hearts, nine brains.

• Heart-1: Chiller
• Heart-2: Boiler
• Heart-3: For now let's assume this as 'X' ;)

As we are in summer Let's talk more about Chiller.

Chiller does not like summer, But summer likes chiller.

Below are some of the problems that could occur during summer.

Airflow: Front yard grass starts to turn greener which is good. She said, "THE GRASS IS (ALWAYS) GREENER" (ON THE OTHER SIDE). This is what exactly happens with the HVAC system. A dirty filter causes low airflow which leads to ineffective cooling.

Waterflow: As weather transitions from winter to summer the cooling coil discharge air temperature may not have a significant drop in temperature. The chillers are operating efficiently. Especially if the system is open to domestic water or rain harvest systems. It is necessary to clean the strainers often.

Below are some images.
