Superheat and Subcooled Levels for Water Source Heat Pumps

This paper evaluates and analyzes the superheat and subcooled levels for water source heat pumps. As per the non-ideal refrigeration cycle, each cycle has a certain amount of superheat in the suction line and a certain amount of subcooled liquid in the liquid line. By evaluating the level of measured superheat and subcooled levels for a known correctly charged system, we can document and publish the results for internal and external use. By connecting temperature gauges to the suction and liquid lines of a system, the superheat and subcooled levels of the system can be found relatively quickly. Charge can be declared to be correct if the values of the superheat and subcooled levels match those of the lab tested values.

Flowmeter Accuracy

When specifying a flowmeter, it is important to know the accuracy. The accuracy of a flow meter can be stated one of two ways; as a percentage of full scale (FS) or as a percentage of reading (RD, also referred to as percentage of rate). It is important to understand the meaning of both so that your flow meter performs as expected and with the desired accuracy.

Understanding Test Standards for Louvers in Hurricane-Prone Regions

In defined hurricane-prone regions, it is particularly important for building design engineers and owners/operators to understand test standards for building products. This article will discuss the basis of wind-speed and load, large-missile-impact, and wind-driven-rain requirements in the latest versions of the International Building Code (IBC) (2012 and 2015) and Florida Building Code (FBC) (2014) relative to wall louvers./p>

Inside Matrix Variable Frequency Drive Technology

From the beginning, VFDs have been used to control the speed of electric motors, which consume approximately 25% of the world's electrical energy in industrial and commercial applications. By definition, VFDs enable a user to operate a motor at any commanded speed, as opposed to running across-the-line at a fixed speed. This variable speed control saves signifcant energy and also lessens the wear and tear on mechancical couplings, such as gear, belts, and pulleys.
