How Cooling Towers Work - Cooling towers use evaporation cooling to cool condenser water from a chiller. Water is pumped to the top of the cooling tower, where the water flows down some flow plates to the cooling tower basin. As the water is flowing down the flow plates air is pulled through the plates and over the water where it releases heat through evaporation. (more…)
Boiler Systems Installation - It is very important to get it right the first time!
Boiler Systems Installation - Purchasing a boiler can be daunting for most people. Many people do not understand boilers and do not know certain components of boiler systems. Typically they trust the installing contractor to outfit and install the boiler with all the proper boiler components.
That includes making recommendations for optional boiler components that increase efficiency and performance. There are resources you can use to try to understand boiler components such as High Performance HVAC. However, overall, this research or study will not make one an expert in boiler installation. We have to trust the boiler installer and the skills of the contractor.
Watts Backflow Preventers | Water Safety - Backflow preventers are necessary on water loops where the water is used in a hydronic loop that heats or cools the water through a boiler or chiller system. This Watts backflow preventer is installed on a large boiler system that heats thousands of gallons of water. The hydronic loops are designed to be hermetic. However, there is always some loss of water somewhere in the system.
For safety purposes to prevent the boiler from losing all of its water, a make-up water loop is connected to the loop. The make-up water feed needs backflow preventers installed in the pipe to prevent any of the boiler or chilled water from getting back to a domestic water feed for the make-up water. (more…)
