HVAC Ratio

When it comes down to selecting a HVAC college program, the first thing that you must ascertain is that the destination college you have chosen has the necessary accreditations. We cannot stress this point highly enough, since it means that the training program imparted will be at par with the standards specified by professional 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 need to select that has at least one accreditation.

It is also important to try and find small class numbers, because then you will get one on one attention from the instructors. A good HVAC college will also have an onsite science lab with modern equipment. Visit the campus and get a feel for the place, the instruction rooms, the facilities available and talk to the senior lecturers, if possible. Also find out whether there is any flexibility in scheduling classes for employed students, and also how you might go about requesting financial aid, if required.

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
