HVAC Ratio

When choosing a HVAC college program, the first thing that you must ascertain is that your preferred choice of college you have selected is an accredited one. This is ultra important, since it means that the training program provided will be at least as good as specified by approved HVAC organizations.

The most prominent accrediting agencies for HVAC training programs are the National Center for Construction Education and Research, which is 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. Select a college that has at least one accreditation.

Smaller class sizes are also important, which means you will receive one on one tuition from the instructors. A good HVAC college will also have an on college science lab with modern equipment. Before enrolling make sure you visit and explore the campus and get a feel for the place, the instruction rooms, the facilities and talk to the teachers, if they are available. Also find out if they provide any flexibility in time-managing classes for working students, and also how you should go about requesting 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
