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.

COVID-19:  A Partnership Approach to Water Treatment Is More Important than Ever

With the impact of COVID-19, the ongoing partnership between plant personnel and your water treatment provider is more important than ever. Water systems, such as cooling towers and boilers, are dynamic systems by design. In today’s environment, they may not be operating as consistently as before with entire processes or facilities being shut down with little warning and, just as quickly, started back up.

How Chillers Work

Factories, warehouses, healthcare facilities, commercial buildings, and office spaces generate unwanted heat that must be removed from the process, equipment, or occupants inside. Chillers may be used to remove this heat by transferring it to the atmosphere either by air or water cooled chillers. At the heart of the chilling process is the evaporation of a liquid refrigerant into a gas. Two basic types of chillers include vapor compression and absorption. In this blog, we will focus on the vapor compression chiller.

Water-Cooled vs. Air-Cooled Equipment

When seeking to cool a large scale commercial or industrial facility, insufficient information often leads to an unsatisfactory solution. While some stakeholders choose water-cooled chillers because they believe the cooling tower in these systems offers more efficiency, others prefer air-based cooling systems because of the less prohibitive upfront price. And with recent technological advances made in both air and water-based chilling systems, determining which option is the right fit has become even more challenging. To decide which system best suits a specific project’s needs, it’s important to understand the pros and cons associated with each option.

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.
