Heating load calculation of hot water boilers and indoor temperature analysis in hospital buildings

 The selected capacity of hot water boilers is often oversize in the design of hospital buildings in North China. In order to reduce the capacity of hot water boilers, proposes a peak shifting operation mode at different loads. The heating capacity of air conditioning will be reduced when heating supply for domestic hot water achieves the peak value, while the heating capacity of air conditioning will be increased when heating supply for domestic hot water achieves the valley value. In order to meet the target of hourly indoor temperature, proposes a method for calculating the hourly indoor temperature with the partial load heating and provides a heat index method for estimating the capacity of hot water boilers.
