New water-saving and energy-saving cooling tower designs come with concerns about change. From the owner to the engineer to the contractor, the question becomes, “Why …
Cooling Tower Design to Save the Planet: Part 2 of 4 – Cycles of Concentration
The combination of water usage and energy usage in open loop cooling towers are a significant cost to owners. Owners are faced with tremendous water …
Cooling Tower Design to Save the Planet: Part 1 of 4 – Drift Eliminators
The combination of water usage and energy usage in open-loop cooling towers is a significant cost to owners. There are ways to reduce the waste …
Cooling Tower Spring Startup Tips
The weather is warming, and our attention turns away from heating and toward system air conditioning. To protect the cooling tower pumps, we offer a …
Tis’ the Season to Start Your Air-Cooled Chillers
Many air-cooled chillers do not have glycol and are drained for the winter season. Most cooling towers are also drained for our cold winter months. …
Strategies for Water Use Efficiency – Cooling Tower Selection – Part V
Today’s building owner’s have many opportunities to improve water use efficiency. ASHRAE Standard 189.1 identifies a few areas to focus on reducing water use specific to cooling towers. The last four issues of Deppmann’s Monday Morning Minutes has discussed specific strategies to improve water use efficiency using current Cooling Tower and Advanced Water Treatment technology advancements in design. [Read more…]
Strategies for Water Use Efficiency – Cooling Tower Selection – Part IV
Most new chillers can now handle variable flow through the condenser providing many opportunities for operational savings. As the cooling tower is an integral part of this system, it is important to understand the effect of flow rate changes and how to insure your cooling tower can provide optimal savings while operating [Read more…]
Strategies for Water Use Efficiency – Cooling Tower Selection – Part III
In this issue, we will discuss the changing requirements specific to “cycles of concentration” in cooling tower applications. In addition, we will review the effect of increasing cycles of concentration and provide solutions to improving these results. ASHRAE Standard 90.1-2010 code change effective 10.18.2013 states [Read more…]
Strategies for Water Use Efficiency – Cooling Towers – Part II
In this issue, we will discuss blow down and cycles of concentration. In addition to water emissions caused by evaporation and drift, cooling towers require blow-down to control the levels of dissolved minerals re-circulated in the cooling tower. These losses are offset or balanced by make up water to both maintain the level of water in the tower and more importantly, [Read more…]
Strategies for Water Use Efficiency – Cooling Tower Selection – Part 1
Open loop evaporative type Cooling Towers by design create emissions of evaporation and drift. Drift emissions from open-loop evaporative type cooling towers are unavoidable. Stand next to a conventional cooling tower and it feels like you might be taking a shower. The amount of drift can vary depending on tower design and will include any water treatment added (chemicals). [Read more…]
