With the ever-growing industrialization and globalization, the need for accelerated cooling and heating devices across industrial, commercial, and residential applications is rising. As a result, more and more HVAC pumps are being installed in manufacturing facilities, office buildings, sports complexes, and others. Read on to learn more about HVAC pumps.
HVAC Pump System: Heating, Ventilation, and Air Conditioning
HVAC pumps control the thermal aspects of a room or building. These aspects refer to moisture, heating, cooling, and temperature improving air quality. The main components of the pump include an indoor air handler and an outdoor unit. The outdoor unit comes with a compressor that circulates refrigerant and absorbs and releases heat as it travels between the indoor and outdoor units.
There are several types of HVAC pumps, but the centrifugal pump is the most common. Centrifugal pumps can be categorized into two groups: volute and axial flow pumps. While the volute pump takes water from the impeller to discharge it to the shaft, an axial flow pump discharges the water parallel to the pump shaft.
Working of the HVAC Pump System
Often known as heat pumps, HVAC pumps use the outside air to heat or cool a home. They can be reversed to either heat or cool an area. These pumps use technology similar to what is found in a refrigerator or air conditioner. It extracts heat from one source and transfers it to where needed. Since most of the heat is transferred, not generated, the HVAC pump system is more efficient than conventional heating solutions like electric heaters.
Think of the HVAC pump as a heat transporter constantly moving air from one place to another, depending on the season. When it's cold outside, HVAC pumps can extract the outside heat and transfer it inside. And when it’s warm outside, it reverses the process and acts like an AC. These pumps are best for moderate climates and require a supplemental heating source for lower temperatures.
Using Variable Speed Pumping in HVAC
It is reported that HVAC pumps equipped with variable speed drives (VSDs) can save significant energy. VSDs play a critical role in energy conservation and allow the pump speed to be decreased or increased, depending on the requirement of the system. Reducing the pump speed will reduce the pump’s pressure and flow, lowering power consumption.
While VSDs can provide an efficient and reliable control to meet the system demand, they will require a higher investment cost. This makes them less suitable for high static or flat system curves. To justify the use of VSDs and ensure a reliable installation, analyze the pump’s suitability for the speed and the benefits of controlling the speed.
