Energy 101, Heating, DHW
A tool that measures temperature using infrared lasers
What is a temperature gun?
A steam system that has a dedicated steam and separate condensate return line
What is a 2-pipe steam system?
Equipment that removes heat through refrigeration cycle
What is a chiller?
Pressure exerted on the walls of the ductwork as air moves through
What is static pressure?
Air leakage entering the building
What is infiltration?
Efficiency % = (Output / Input) * 100
What is Building Efficiency?
Return pipes above the boiler water line
What is a dry return?
The method buildings use by shifting energy use to off peak hours to save money
What is pre-cooling?
Dilutes contaminants from lab exhaust before discharging vertically at high speeds and prevents re-entry into air intake
What are strobic fans?
Layer of metallic foil that blocks radiant heat and reflects the heat back towards the source
What are radiant barriers?
The logic of running 2 machines at a lower efficiency rather than running 1 machine at a higher efficiency
What is lead lag?
A steam trap that has an continuous modulating flow as an expected ultrasonic sound
What is a float and thermostatic steam trap?
Chemicals that kill or inhibit microorganism growth
What are biocides?
Compares measured static pressure to the setpoint and adjusts the supply fan speed to deliver enough air to maintain the static pressure
What is Duct Static Pressure Control Loop?
Automatically modifies the times for turning on or off and time updates are resolved automatically for every day of the year.
What are astronomical timers?
