Abstract

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.

Description

technical field [0001] The invention relates to the field of phase-change materials, in particular to an energy-saving system based on phase-change material energy storage central air-conditioning for off-peak operation. Background technique [0002] Phase change energy storage materials refer to materials that can exchange energy with the external environment (absorb heat from the external environment or release heat to the external environment) during the phase change process, so as to achieve the purpose of controlling the environmental temperature and utilizing energy. Compared with sensible heat energy storage, phase change energy storage has the advantages of high energy storage density, small size, constant temperature control, remarkable energy saving effect, wide selection range of phase change temperature, easy control, etc., and has important application value and Broad prospects. [0003] Peak staggered power consumption reduces the peak power load and ensures t...
