sprawność temperaturowa - Opis:
- In order to reduce ventilation heat loss and improve energy efficiency of low-energy buildings air-handling units (AHUs) with heat recovery are used. The article presents results of surveys performed in a passive building located in Katowice concerning the temperature efficiency of heat and cold recovery of two selected AHUs, with different heat exchangers. For this purpose the measurement data from the Building Management System (BMS) for the period 1.08.2015-31.07.2016 were used. The first unit was equipped with a rotary heat exchanger. Its average annual temperature efficiency of heat recovery was 47.2% annually. The efficiency of cold recovery amounted 52.9% on average for the warm half year. The second unit had a cross-flow exchanger. The average annual temperature efficiency of heat recovery in this device was 80.1%. The efficiency of cold recovery amounted 57.2% on average for the warm half year. Additional remarks concerning the temperature measurement in analysed units were also given.
