Buildings adopt heating, ventilation, and air conditioning (HVAC) systems to increase the comfort, efficiency, and safety of occupants. As the HVAC system accounts for 50-60 % of a building’s energy use which is quite significant, the use of an HAVC drive is recommended for energy saving.

Our Hx2000 HVAC Drives are specifically designed to meet the demands of today’s HVAC systems. The Hx2000 HVAC Drives control the speed of pump, fan, and compressor motors used in air handling units, cooling towers, chillers, and other HVAC applications.

How to conserve energy in buildings using VFDs for HVAC applications?

HVAC (Heating, Ventilation, and Air Conditioning) systems are typically designed for peak load conditions, which vary dynamically.

Variable Frequency Drives (VFDs) are implemented for process control in HVAC applications like Fan, Pump and compressor.

VFD adjusts the motor’s operating speed based on dynamic load conditions

A 20% speed reduction results in upto 50% saving in power.

Thus VFD helps to Conserve energy, improve equipment life and reduce maintenance costs when used in HVAC applications.

Multi-Motor Control (MMC): Booster Pump

MMC is used when a single Drive is required to control multiple motors in pump systems.

It can control 1 main motor through PID and 8 auxiliary motors through Drive & Relays, an Ideal cost-effective solution for constant pressure / constant flow pumping application.

Pump Clean Operation

Scraps, which get built up in the impellers of pumps, decrease the efficiency of motor performance. Through consecutive FWD/REV or ACC/DEC operations, the scraps get eliminated.

This results in an extension of pump lifespan and energy saving. The pump clean mode is initiated by a remote signal, current profile or power profile.

Dry Pump (Under Load Protection)

Prevents pump damage when there is insufficient water in the tank. If Actual load is under the Under Load (UL) Detect curve, Inverter will trigger warning or trip signal to protect the pump.

Flow Compensation

In a system for longer pipes & higher flow rate, causing great pressure drop, this feature helps to compensate for pressure drop by increasing the PID reference.
