The invention discloses a central air conditioner off-peak operation energy-saving
system based on
phase change material
energy storage, and relates to the field of
phase change materials. The central air conditioner off-peak operation energy-saving
system based on
phase change material
energy storage comprises a power supply module used for supplying 220V
alternating current, an off-peak control module, a
delay control module and a switch
voltage reduction module; the off-peak control module is used for conducting a circuit during the
electricity utilization trough period and controlling a switch of the switch
voltage reduction module connected with a live wire to be conducted; the
delay control module is used for conducting the circuit after
delay after the off-peak control module is conducted, and controlling the switch of the switch
voltage reduction module connected with a null line to be closed; and the switch
voltage reduction module is used for converting 220V
alternating current into
alternating current lower than 220V after being switched on. Compared with the prior art, the central air conditioner off-peak operation energy-saving
system has the beneficial effects that
energy storage is conducted on a phase change energy
storage material in the
electricity utilization trough period,
electric energy is converted into
heat energy, heat release is conducted through the phase change energy
storage material according to the indoor temperature in the
electricity utilization peak period, the
heating effect of a central air conditioner is achieved, indoor temperature adjustment is guaranteed, and meanwhile,
electric power resources can be effectively saved.
