Pumps and Commercial HVAC Installation

Pumps and Commercial HVAC Installation




Among all the elements of any commercial HVAC installation, centrifugal pumps are one of the most vital. They sustain cooling towers, boilers, water systems, hydronic systems, and chillers. The centrifugal pump efficiency of a commercial HVAC system depends on how well the pump is controlled, how well the pump and motor work, and how well maintained the pump and the other heating and air conditioning elements are. Though pumps have made minor changes over the years, they are nevertheless essentially the same as they originally were. Nearly every major part of any commercial HVAC installation has been greatly alternation to be energy efficient and more effective. Centrifugal pumps, however, have only made small changes in design, structure, and material.

It is only recently that the issue of centrifugal pump efficiency has been raised. Now that changes are being made by way of high efficiency pumps and excursion motors, less energy is required to use them. In addition to these recent upgrades, more progressive and precise pump controls are being introduced into the marketplace which are giving newer commercial HVAC systems an advantage over the old systems. Though the energy consumption for the pump is low, it is used regularly, meaning that already minor improvements in design and efficiency can have meaningful impacts on energy costs.

The newer controls on centrifugal pump designs can help dictate the flow of water in air conditioning and heating appliances. Variable frequency drives are now able to control pumps for a variety of situations arising from the use of a commercial HVAC. For an average commercial HVAC installation, an upgraded centrifugal pump with variable frequency drives saves anywhere from twenty to fifty percent on energy consumption over the time of a year. Intelligent pump controllers are a new upgraded version of pumps for commercial HVAC applications. Intelligent controllers can be hooked up to monitors the function of the pump and can alert to malfunctioning parts or a damaged centrifugal pump. They can be programmed in improvement to conquer shared problems and self control themselves without halting heating or air conditioning roles.

Although pumps are being improved, regular maintenance is nevertheless necessary. If maintenance is put off, the operation of the pump may fail and cause damage to the system. Maintenance experts must be trained to work with variable frequency drives and intelligent pump controllers in order to keep them working efficiently. If an HVAC contractor is unfamiliar with the software used for the newer models they will not be able to check for problems with calibration and function. The centrifugal pump should be regularly inspected for abnormal function or failure. If it is making uncommon noises or vibrations it may indicate that it needs to be repaired. Once a pump reaches the end of its life, maintenance experts should determine why the pump wore out. If they simply replace the pump without calculating the reason behind why it failed, the new pump may very well fail, too. Reasons for a pump failing are poor design, a defect in the pump itself, poor care and maintenance, and improper operation.
