Reducing Water Costs in Building HVAC Systems

The HVAC system is the largest user of energy and water in typical commercial buildings. In the past, energy costs overshadowed water costs. Recent droughts and the need to expand municipal water supplies to support growth have led to increased water costs nationwide. Combined with the focus on water conservation in green buildings, the payback associated with reducing building water usage is greater than ever. Most commercial buildings use water cooled chillers to provide air conditioning because they are much more energy efficient than air-cooled chillers. Achieving these efficiencies, however, requires large quantities of water to operate a cooling tower. Most buildings also use re-circulating hot and chilled water loops to distribute heating and cooling throughout the building. Although not designed to routinely use water, these systems can use large amounts of water if undetected leaks occur. As the major consumer of water, the building HVAC system is an obvious target for water conservation efforts and often provides significant saving.

How Do Adiabatic Cooling Systems Work?

In terms of raw energy efficiency and the ability to provide precise cooling under fluctuating load conditions, recirculating evaporative cooling water systems with chillers or heat pumps are the most efficient way to remove heat from a process or building air. However, adiabatic cooling systems can be a good fit with an overall lower cost for heat removal in some climates and applications.

What is Scale and How Does it Impact Water Treatment?

Hard water has been causing issues for humanity for ages, whether it is making it difficult to wash our clothes and cars, or depositing on our hot water heaters and kettles. Hardness scale is typically the combination of calcium and magnesium compounds that have precipitated out of water (e.g., calcium carbonate, magnesium silicate). This tough deposit forms in HVAC cooling systems and process water systems and can wreak havoc by decreasing system life and increasing energy usage, maintenance, and operational costs.

How To Prepare Your Cooling Towers for Winter

With the cooler months upon us, it is important to prepare your cooling towers for freezing temperatures. Even in extremely icy conditions, cooling towers can be operated successfully if proper precautions and protocols are followed. A frozen cooling tower is a major issue for business operations as well as from a cost standpoint.  Now is the time to prepare for winter weather.
