Abstract :
According to the present problems of existing office buildings using air source heat pump, countermeasures were brought forward to solve the problems, such as changing part of the present air source heat pumps to water-cooled cold water units, changing present units into new air source heat pumps and pump variable frequency renovation. According to the case study in this paper, the static return period are 2years, 5-7years and 1-4years for each measure.
