A condensate pump is a specific type of pump used to pump the condensate produced in an HVAC (heating or cooling), refrigeration, condensing boiler furnace, or steam system. [ 1 ] Applications
To aid in the study, AMCA sponsored research by the Battelle Memorial Institute to compare the test results using the pitot tube test methods and nozzle test methods. The result of this effort was a new revision of the test code, which was published in 1960 as AMCA Standard Test Code for Air Moving Devices, Bulletin 210. Standard 210 became ...
A pedestal sump pump with a float switch. A float switch is a type of level sensor, a device used to detect the level of liquid within a tank. The switch may be used to control a pump, as an indicator, an alarm, or to control other devices. One type of float switch uses a mercury switch inside a hinged float.
These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.
National and international test codes are used to standardize the procedures and definitions used in testing large condensers. In the U.S., ASME publishes several performance test codes on condensers and heat exchangers. These include ASME PTC 12.2-2010, Steam Surface Condensers, and PTC 30.1-2007, Air cooled Steam Condensers.
An air flow meter is a device similar to an anemometer that measures air flow, i.e. how much air is flowing through a tube. It does not measure the volume of the air passing through the tube, it measures the mass of air flowing through the device per unit time, though Thus air flow meters are simply an application of mass flow meters for the ...
