A fundamental truth that applies to improving employee job performance is that the degree of success improving any outcome, including the functioning of an HVAC system and employee job performance, is determined by whether all relevant interventions are used to achieve the desired improvement.
Bob receives a call from the dispatcher telling him about a restaurant that is having difficulties. When he gets on the roof at the restaurant he notices that the unit's fan motor is turning, but seems to be very slow. As he approaches the condensing unit, the fan stops. With Btu Buddy's help, Bob diagnoses the problem.
It may sound like the plot from a science fiction movie - through genetic testing, someone finds out she may develop a serious disease, her company finds out and fires her, and she can’t get health insurance because of this future health risk. Congress, though, took steps to ensure this scenario does not become reality.
Imagine a lightweight, flexible material that effectively insulates pipes in steam distribution systems. You don’t have to imagine anymore. With DOE assistance, Aspen Aerogels developed insulation that provides the same insulating capabilities as conventional products, but with up to five times less material.
TKDA, an employee-owned engineering, architecture, and planning firm, has received a national award for its design of an innovative, environmentally friendly steam generating facility for Andersen Corp. The award was given by the American Council of Engineering Companies (ACEC) at an event held in Washington, D.C.
Space heating and lighting consume most of the energy in non-refrigerated warehouses. Installing more efficient lighting to save energy has been well documented by computer modeling. But what about space heating? This article summarizes an energy modeling analysis showing energy performance for six types of gas-fired heating systems commonly used in warehouses.
In this issue’s troubleshooting situation, the problem unit we’re facing is a reach-in refrigerator in a restaurant and the customer’s description of the problem is that they discovered spoiled food in the cabinet when they arrived early in the morning prior to opening.
The memory of consumers is short. Your customers and prospects will not remember an advertising message that they see or hear just once or twice. The message has to be repeated. For advertising to be successful, your message has to have sufficient frequency and continuity.
Voltage unbalance degrades performance and shortens the life of a three-phase motor. It causes phase current unbalance far out of proportion to the voltage unbalance. Unbalanced currents lead to torque pulsations, increased vibrations and mechanical stresses, increased losses, and motor overheating, which results in a shorter winding insulation life.
Bob gets a call to go to an office building where its water-cooled chiller is not cooling the building. Bob finds that the suction pressure is a little low and the head pressure is about right but the unit is not cooling the water down to the 45°F design setting. Btu Buddy helps him in going step by step to solve the problem.
