Title:
CENTRAL HEATING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/214690
Kind Code:
A1
Abstract:
A central heating system, comprising: a steam boiler room (100), a steam compression heat pump device (200), an absorption heat pump device (300), a heat exchange zone (400) for a heat network at high temperature, a heat zone (500) for the heat network at low temperature, another heat device (600) for the heat network at low temperature and a low-temperature residual waste heat energy collection device (700). A steam output pipeline (110) and a compression recycling steam pipeline (210) are provided between the steam boiler room (100) and the steam compression heat pump device (200); a compressed steam driving source pipeline (220) and a pipeline (310) for a low-temperature heat source located behind an absorption heat pump are provided between the steam compression heat pump device (200) and the absorption heat pump device (300); and an absorption heat pump heat supply hot water pipeline (320) and an absorption heat pump heat supply water return pipeline (120) are provided between the absorption heat pump device (300) and the steam boiler room (100); By employing the described central heating system, low-temperature heat supply loads within all regions establish low-temperature heat supply regions, and therefore, the quantity of extracted heat is large, and the efficiency is higher.
