Energy Recovery Wheels | HVAC Enthalpy & Heat

As the cost of energy rises engineers are looking for ways to improve and increase energy efficiency. Aside from HVAC equipment with higher energy efficiency rates, improving structures for less heat loss and heat gain, and building automation systems giving the equipment precision control for better efficiency of the equipment, there are other ways to increase energy efficiency inside buildings. One of the ways to increase energy efficiency inside buildings is to add energy recovery wheels to the economizer systems. A US Department of Energy study concluded energy recovery wheels can save over 15% of the energy used in commercial HVAC applications.

Boiler Piping Plant Renovation | HVAC Hydronics

Boiler Piping Plant Renovation – Hot Water Boiler Piping for a commercial boiler application. Boiler project being renovated and getting all new DDC controls for optimum hydronic control and efficiency. Boilers are an excellent way of providing good hot water heat to a large building or community. Some people refer to them as furnaces, hot water heaters, hot water heating systems, or hot water heater but the proper name is to call them hot water boilers. Hot water gas boilers provide clean draftless hot water heat through pipes and piping systems which HVAC professionals refer to as hydronic piping. Typically, hot water heating systems use pumps or circulators to move the water through the hot water piping system. Hot water heat is considered to be a good source of draftless heat by the people who have these hot water heating systems installed in their homes and businesses. Continue reading

Fan Maintenance and Energy Savings

Fan Maintenance and Energy Savings

Proper HVAC Fan Maintenance and Control can save Energy Dollars

According to the Department of Energy fans consume nearly 80 billion kilowatts of energy per year. Optimizing how fans work functionally in mechanical applications can reduce energy use and save energy dollars for end users. Assuming the design engineer selected the proper fan and proper installation in well designed system what can a facility manager do to save energy dollars and increase performance by looking at the fan systems in their building(s)? To make a good evaluation you need to look at several different factors in fan operation.

  • Fan Control
  • Fan Performance
  • Installation
  • Ductwork
  • Fan Maintenance
