Abstract:

This paper presents the calculation and estimation the ambient temperature bin data, the main parameters used in the bin temperature method, and the energy analysis of air conditioning systems. Based on the average monthly environmental temperature data and the average monthly total radiation data in QCVN 02:2022/BXD, the ambient temperature bin data for 03 cities representing different climate zones of Vietnam were established. The calculation results show that a calculation method is completely feasible to establish environmental temperature bin data in other regions of Vietnam. The paper contributes to the proposal to upgrade TCVN standards and regulations to make the calculation of energy efficiency for air conditioners in Vietnamese climate conditions more accurate.
