VLT HVAC Basic Drive Design Guide 2.5.13 The VLT Solution While dampers and IGVs work to maintain a constant pressure in the ductwork, a frequency converter solution saves much more energy and reduces the complexity of the installation. Instead of creating an artificial pressure drop or causing a decrease in fan efficiency, the frequency converter decreases the speed of the fan to provide the flow and pressure required by the system.
Introduction to VLT HVAC Ba... VLT HVAC Basic Drive Design Guide 2.5.14 Constant Air Volume CAV, or Constant Air Volume systems are central ventilation systems usually used to supply large common zones with the minimum amounts of fresh tempered air. They preceded VAV systems and therefore are found in older multi-zoned commercial buildings as well.
VLT HVAC Basic Drive Design Guide 2.5.16 Cooling Tower Fan Cooling Tower Fans cool condenser water in water cooled chiller systems. Water cooled chillers provide the most efficient means of creating chilled water. They are as much as 20% more efficient than air cooled chillers. Depending on climate, cooling towers are often the most energy efficient method of cooling the condenser water from chillers. They cool the condenser water by evaporation.
Introduction to VLT HVAC Ba... VLT HVAC Basic Drive Design Guide 2.5.18 Condenser Pumps 2 2 Condenser Water pumps are primarily used to circulate water through the condenser section of water cooled chillers and their associated cooling tower. The condenser water absorbs the heat from the chiller's condenser section and releases it into the atmosphere in the cooling tower.
2 2 Introduction to VLT HVAC Ba... VLT HVAC Basic Drive Design Guide 2.5.20 Primary Pumps Primary pumps in a primary/secondary pumping system can be used to maintain a constant flow through devices that encounter operation or control difficulties when exposed to variable flow. The primary/secondary pumping technique decouples the “primary” production loop from the “secondary” distribution loop.
Introduction to VLT HVAC Ba... VLT HVAC Basic Drive Design Guide 2.5.21 The VLT Solution Depending on the size of the system and the size of the primary loop, the energy consumption of the primary loop can become substantial. A frequency converter can be added to the primary system, to replace the throttling valve and/or trimming of the impellers, leading to reduced operating expenses. Two control methods are common: The first method uses a flow meter.
VLT HVAC Basic Drive Design Guide 2.5.22 Secondary Pumps Secondary pumps in a primary/secondary chilled water pumping system distribute the chilled water to the loads from the primary production loop. The primary/secondary pumping system is used to hydronically de-couple one piping loop from another. In this case. The primary pump is used to maintain a constant flow through the chillers while allowing the secondary pumps to vary in flow, increase control and save energy.

VLT HVAC Basic Drive Design Guide 2.6.3 Control Structure Closed Loop The internal controller allows the frequency converter to become an integral part of the controlled system. The frequency converter receives a feedback signal from a sensor in the system. It then compares this feedback to a set-point reference value and determines the error, if any, between these two signals. It then adjusts the speed of the motor to correct this error. 130BB894.

For example: The coil known as ‘coil 1’ in a programmable controller is addressed as coil 0000 in the data address field of a Modbus message. Coil 127 decimal is addressed as coil 007EHEX (126 decimal). Holding register 40001 is addressed as register 0000 in the data address field of the message. The function code field already specifies a ‘holding register’ operation. Therefore, the ‘4XXXX’ reference is implicit.
