Application of off-peak electricity auxiliary heat source based on air-source heat pump system

For areas of large gap between peak and valley loads of electric power, increasing use of off-peak electricity can reduce the peak-valley difference, which is not only conducive to the rational allocation of electric power, but also an important energy saving measure. Elaborates the application of off-peak electricity as auxiliary heat source to electrically driven air-source heat pump system in Urumqi and the method for determining the capacity of the auxiliary heat source equipment.
