- ESP-Design and Application for the HVAC Industry
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...
Pulse-Power Water Treatment as a Green Scale Inhibitor for HVAC and Once-Through Industrial Systems
Untitled Document Introduction The search for a nonchemical way to reduce scale formation has been the Holy Grail of those seeking a green solution to this problem. Chemical water treatment can be successful at controlling scale; however, the problems associated with adding chemicals with various degrees of toxicity are factual. Chemicals in the concentrated form are often acute toxins, and their chronic toxicity in the diluted form is often uncertain....
