Title:
MID-DEPTH UNDERGROUND PETROTHERMAL HEAT SUPPLY SYSTEM, AND HEAT SUPPLYING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/078306
Kind Code:
A1
Abstract:
A mid-depth underground petrothermal heat supply system, comprising: at least one underground mid-depth rock and soil heat exchange system (1), an aboveground auxiliary thermal system (2), a heat supply terminus thermal circulation system (3), and a control system (4). When the temperature of a heat exchange medium that performs heat exchange in the underground mid-depth rock and soil heat exchange system (1) reaches a preset temperature, the heat exchange medium is transmitted to the heat supply terminus thermal circulation system (3) by means of a direct supply apparatus of the aboveground auxiliary thermal system (2). When the heat exchange medium does not reach the preset temperature, the heat exchange medium is heated by means of a heat exchange heat pump apparatus (21) of the aboveground auxiliary thermal system (2), and transmitted to the heat supply terminus thermal circulation system (3). The present invention solves the problem in existing water source heat pumps of environmental water pollution and insufficient heat source stability, and effectively prevents pollution of water resources and is able to provide a continuously stable heat source.
