EIGHT WAYS TO CONSERVE ENERGY WITH HVAC MAINTENANCE

Ways to Save Energy with HVAC System

1. MAINTAIN PROPER SYSTEM BOUNDARIES

Overseeing system borders by managing cooling and heating to designated spaces can improve HVAC energy effectiveness by as much as 20%. Limits can be adjusted according to the operating environment and season. A garage or filling area might not be warmed or cooled at all, depending upon the time of year. An open storage facility might have open entryways and doors at times between seasons, but be sealed and warmed or cooled at other times. An energy audit or commission for energy conservation in new structures needs that system limits be specified to know what those settings must be and when, where the borders lie and how airflow from HVAC ducting ought to be directed.

2. MAINTAIN DAILY; SEASONAL THERMOSTAT SET POINTS

A programmable thermostat positioned to manage air existing and temperature level to provide affordable comfort levels at various times of the day and year produces an economical cooling and heating operation. A pre-set schedule includes shows heat or a/c to maintain temperature levels for particular time blocks within a day. Adjusting the temperature settings for spaces that are not inhabited through the day or night can save as much as 10% in energy usage.

3. USE AUTOMATIC CONTROLS WHERE POSSIBLE

Automatically controlling the speed, output, and run-time of HVAC devices such as fans, chillers, and compressor motors allows the whole system to be managed to offer proper amounts of heating and air conditioning. For example, the installation of a variable air valve into the air system of an Indiana school was utilized to manage airflow. This and other programmable energy features saved about 25% on the school’s electrical bills while keeping student comfort at suitable times of every day throughout the academic year.

4. MAINTAIN EQUIPMENT SET POINTS.

Make sure that devices set points are reasonable to accomplish desired comfort levels, which they aren’t working more than required. Devices such as fans and blowers ought to be set to run at speeds that deliver the required air required by the area borders they serve. Systems often provide more than what is needed and are not set correctly. They consume more power to produce a higher heating or cooling result than is required, reducing energy performance. Carrying out determined set points will avoid this and lead to energy cost savings.

5. ADJUST AND SET HVAC OPERATION FOR SEASONAL CHANGE.

Raising the temperature level of the system’s chiller water supply to a level that can accomplish needed temperature settings and levels will assist save energy. Depending on the setup of the system, managing the temperature of cooling water to your chiller, within maker’s standards, can attain the desired comfort level and consume less power. In fact, this can be a big energy saver as the compressor does not have to work as hard while keeping the preferred convenience level. Be conscious that a modest modification in temperature setting may be all that is required when the season changes. This alone might result in noteworthy energy savings.

6. CONSIDER VARIABLE SPEED EQUIPMENT.

Heating & cooling with variable speed options for fans, blowers, motors, and other components have enhanced energy effectiveness for many business centers. Over the last decade, a/c unit and thermal equipment have included variable speed functions to develop more cost-effective and efficient os. Performance depends on the ability to set up settings appropriately and in preventing motors, fans and operational elements from performing at their optimum created speed at all times. Variable speed control permits the devices to be set for what is essential, less than 100%, and still fulfill the heating and cooling demands.

7. APPROPRIATELY SPECIFY AND SIZE YOUR SYSTEM.

Accomplishing facility climate conditions while conserving energy depends on an appropriate HVAC compressor and chiller size. Purchase enough tonnage and capability for your systems based on the temperatures demanded throughout the year. Significant apparatus in little locations will run at optimal speeds and take in big volumes of power, while a small system is put under pressure for larger areas, reducing comfort– if the wrong size devices are used. The Air Conditioning Contractors Association of America (ACCA) Manual J ² provides standardized guidelines on the proper cooling sizing requirements. The manual deals with correct analyses of insulation, wall, ceiling and floor locations, consisting of possible leakage of ducts. 

Make sure that HVAC systems and parts are on a disciplined, time-based maintenance schedule and that information is recorded quickly. Establish a basic HVAC maintenance checklist that Includes, at a minimum, the following actions:.

– Audit your HVAC size for the size and capacity of any equipment additions. Statistics have revealed that lots of specialists typically improperly install oversize units. The inning by the ACCA, it is much better to set up a smaller sized unit that can preserve the load. Bigger equipment decreases energy conservation, walkings energy costs and compromises a/c durability.

– Clean and change air filters and check thermostat set points routinely. Optimum HVAC effectiveness is attained with scheduled maintenance. Filters blocked by carbon particles and dirt need to be replaced, coils cleaned to decrease overheating, and wear on parts determined. Thermostat assessments can discover bad set points or faulty operation triggering continuous energy intake. Faulty thermostats need immediate repairing or complete replacement to bring back a comfortable, efficient space.

– Check for refrigerant leakages frequently. A leakage will lower the system’s active operation and reduce its efficiency. If not repaired, the capacity of the system can be jeopardized, and irreversible damage might result. When systems are unable to provide a useful and productive output, compressors may be overworked because of leakages in the system. A careful assessment of leakage within the system and the system offers HVAC durability along with efficient operation.

– Check all drain and pan drip lines regularly. Must system condensate connections become blocked, the excess moisture can migrate and spill out of drip pans, triggering a multitude of problems. An accumulation of water likewise increases the danger of fungal development and mold.

This eight-step approach to handling and keeping your HVAC system will guarantee ideal efficiency, lower energy consumption and appropriately meet the needs of your center and its residents.
