HVAC Ratio

When choosing a HVAC college program, the most important point that you must find out is that your preferred destination college you have selected is an accredited one. We cannot stress this point highly enough, as it means that the training provided will be at least as good as specified by approved HVAC organizations.

The premier accrediting agency for HVAC training programs are the NCCEA, the Partnership for Air-Conditioning, Heating, and Refrigeration, HVAC Excellence, North American Technician Excellence and Research, Environmental Protection Agency, and the Occupational Safety and Health Administration. You MUST select a college that has at least one accreditation.

It is also important to try and find small class numbers, because then you will get one to one attention from the program teachers. A good HVAC college will also have an on-campus science laboratory with professional-grade tools. Before enrolling make sure you visit and explore the campus and get a feel for the place, the classroom, the overall facilities offered and talk to the faculty, if possible. Also find out whether there is any flexibility in scheduling classes for employed students, and also how you should go about researching financial aid, if you might need it.

Chapter 4.9: HVAC System Short type questions 1. Define ‘tons of refrigeration’? Ans Energy Efficiency Ratio mainly used in air condition systems. Performance of smaller units and roof top units are frequently measured in EER rather than kW/ton.

9. Energy Performance Assessment of HVAC Systems QUESTIONS 1) What is meant by a ton of refrigeration? 2) Define the terms net refrigeration capacity, COP, energy efficiency ratio.

Heating or Cooling of Air – without moisture gain or loss – straight line on psychrometric chart since humidity ratio is constant Chapter 3 – Basic HVAC Calculations Cooling and Dehumidifying Air Moist air brought down below its dew point temperature

The damper position and therefore the mixed air temperature and humidity ratio are not linearly related to damper position. After the mixing box has been commissioned, the results of the functional test can be used to calibrate a model of the actual behavior. Te Tr
