Explosion Proof UV Lights for Commercial and Industrial HVAC systems
In the past decade, more and more people have been installing UV lights in their HVAC systems to eradicate harmful bacteria. A timely study from Duke University Medical Center has proven the effectiveness of using UVC bands to disinfect a myriad of dangerous microbes, including drug-resistant bacteria, such as Acinetobacter, Clostridium difficile and vancomycin-resistant enterococci (VRE). During the research, scientists concluded that UV light (specifically, UVC), if properly applied, can remove up to 97 percent...
Advice from HVAC experts!
HVAC systems (cooling and heating) can use 60-70% of the overall energy in your facility. Proper maintenance is one of the key recommendations for maintaining your system’s performance. To really help extend the life of your system, itcould be something as simple as changing and cleaning the filters regularly. If you have a large organization, make sure your maintenance staff has a consistent schedule for looking over each aspect of the HVAC system. These include filters, wiring, heat exchange, supply and...
Rating criteria for vehicle in-cabin noise with emphasis on HVAC system operation
Noise and vibration have an important influence on a customer's perception of vehicle quality. It is the purpose of this study to introduce a standard test procedure for measuring vehicle in-cabin noise levels. A combined vehicle base noise with all possible sources, including HVAC system, tyres, aerodynamics, under various driving conditions, is considered for developing the total vehicle cabin noise rating criteria. Results from 21 different vehicles were analysed and used to determine a star rating for the...
Refrigerant Gas Tracking: The importance of AC/HVAC system maintenance
Refrigerant gases are used in commercial facilities such as office buildings, hospitals and warehouses to maintain the climate and air quality. Refrigerant management includes maintaining the air conditioning (AC) or heating, ventilating and air conditioning (HVAC) units often used to maintain the environment in these buildings.Refrigerant gases have been around for many years. These gases are basically condensed under pressure to obtain chilled air. Through the repetitive evaporating and condensing actions of...
Minimizing Refrigerant Emissions in HVAC Systems
Managing the operation and maintenance of a facility's air conditioning equipment has always been a major responsibility, as chillers often represent the single largest electrical load in a facility. Since the annual cost of operating chillers is a major component in both the electrical and maintenance budgets, engineering and maintenance managers should take the necessary steps to ensure systems operate efficiently, effectively and safely. The phaseout of ozone-depleting refrigerants has made management of...
