A Guide To Heating Ventilation And Air Conditioning
Heating ventilation and air conditioning is also known as climate control or HVAC. It is quite important in design of medium to large office and industrial buildings. Heating ventilation and air conditioning is based on the principles of heat transfer, thermodynamics and fluid mechanics. The three functions of ventilating, air-conditioning and heating are closely interrelated as they all seek to give good indoor air quality, provide thermal comfort and reasonable costs of installation, operation and maintenance.
Heating ventilation and air conditioning systems reduce air infiltration and provide ventilation. For larger buildings, HVAC systems are analysed, designed and specified by the engineers.
Heating Ventilation And Air Conditioning Purchasing Tips
Getting a ENERGY STAR heating ventilation and air conditioning is the best way to qualified high efficiency unit. To determine the size, you need to calculate the cooling load of the building. Flexible- flow positions, economizers and programmable controls can drastically improve the performance of your unit. To maximize the installed efficiency, do comprehensive testing, adjusting and balancing of installed unit. Regular maintenance and proper operation is the key to preserve the long-term efficiency of your heating ventilation and air conditioning unit.
Saving Costs Using Heating Ventilation And Air Conditioning
You can adjust the schedule at workplace to reduce usage of energy at peak hours. Close doors to maintain the desired temperature inside the room. Adding controls to the exhaust fan enables to shut it off when not in use. Regular maintenance of heating ventilation and air conditioning can save up to 30% of fan energy and 10% of space conditioning energy. This maintenance includes cleaning condenser coils, chaning filters and belts, fixing duct leaks, inspecting leaky heating ducts, fixing steam leaks, cleaning heat exchanger surfaces and blower coils and adjusting dampers, drives, linkages and valves. Install a time clock to turn off the system when the building is not in use, as it will reduce the air conditioning and heating hours.
When repairs are required for fan and pump, it is better to replace them with premium efficiency models that will annually save 35-45% on your investment. Heating ventilation and air conditioning is a specialized field just like central heating and air conditioning and if you are facing any problems, call certified professional. If you want to try your hands on the unit, you must grab the HVAC handbook that describes some basic terms, servicing and guide to troubleshooting.
HVAC industry offers career opportunities including maintenance and operation, equipment manufacturing and sales, system design and construction and in education and research.
