How Optimizing Variable Refrigerant Flow Cooling Systems can Save Building Managers on Energy Usage

EES is very active with several Variable Refrigerant Flow, VRF, cooling systems’ manufacturers. In this article the condenser-water optimization on Samsung equipment will be discussed.

As in years past, the employees of EES, along with their families and friends, descended upon the home of Dan & Christina Luna for an afternoon of food, fun, sunshine, and swimming. There were several families’ young children, all of whom ended up riding on the “inflate-a-bull”.

Continuing where we left off with optimizing chilled water flow, this article is taking a look at cooling tower control for the same large shopping mall in the DC area. When EES showed up for the first time on site at the chiller/tower plant, the tower control was terrible. The control was “tuned” by the client’s local HVAC tech, and it went from off, to 90%, to off, every few minutes.

As part of an overall optimization and takeback of a commercial mall in Virginia, EES engineers, step by step, enhanced systems to make a chilled-water plant more efficient. This article is about optimizing the chilled water pumping and pressure loops. In future articles, we’ll dig into condenser water loops and the overall plant optimization.

Lighting based on time clocks can sometimes feel like it’s a draining the life out of your wallet. EES tackles this problem with a simple, closed-loop control solution.

It has become common practice to build underground or under-building parking lots for facilities. Each structure requires a CO monitoring system that jumps in to action when the level of CO gas becomes too high. Every one of these systems requires periodic (semi-annual) calibration and testing to protect the patrons and the building owners.

Sunday, March 12th, we'll 'spring forward' an hour on our clocks. Soon, Congress is going to vote to put to rest the yo-yoing of clocks twice a year.  If and when it does become law, we will be staying this way "forever." But is this a good or a bad thing?

When you retrofit Rockwell SLC Hardware that has reached it’s end of life, you transform old equipment to perform like new again.

With today’s ubiquitous device connectivity, protecting your building management and transportation system operations from cybersecurity attacks is imperative. Sophisticated criminals have developed the means to shut down and disrupt operations from anywhere in the world. Vice President of Engineering Dan Luna shares tips and three tools to maintain the security of your system.
