5. 4. Heat recovery units in ventilation : Investigation of the heat recovery system for LB20 and LB21 in Building 99, University of Gävle

   University essay from Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

   Author : Marta Duarte; [2016]
   Keywords : Heating ventilation and air conditioning systems; heat recovery ventilation; run-around heat recovery; temperature ratio; sensible effectiveness;

   Abstract : Heating, ventilation and air-conditioning (HVAC) systems are widely distributed over the world due to their capacity to adjust some local climate parameters, like temperature, relative humidity, cleanliness and distribution of the air until the desired levels verified in a hypothetical ideal climate. A review of buildings’ energy usage in developed countries shows that in the present this energy service is responsible for a portion of about 20% of the final energy usage on them, increasing up to 50% in hot-humid countries.
