Intelligent-control medium-deep-depth geothermal non-interfering heating system capable of achieving whole-process energy saving

Abstract

The invention discloses an intelligent-control medium-deep-depth geothermal non-interfering heating system capable of achieving whole-process energy saving. A buried tube heat exchanger is arranged ina geothermal well, a ground source side water pump communicates with the buried tube heat exchanger and communicates with a user side water pump through a heat pump host for heat exchanging, the userside water pump communicates with an indoor space of a user side, an energy-saving intelligent control system is connected with the ground source side water pump, the user side water pump and the heat pump host through a first variable frequency cabinet, a second variable frequency cabinet and a heat pump unit control system correspondingly, a temperature sensor is arranged in the indoor space ofthe user side, a pressure sensor is arranged at the most unfavorable tail end of the user side, and the energy-saving intelligent control system integrally adjusts the power of a unit water pump. Through the technical scheme, medium-deep-depth geothermal non-interfering clean utilization is achieved, the minimum total energy consumption of all main power consumption equipment is achieved, and meanwhile the stability, reliability and user comfort of the geothermal heating system are ensured.

Description

technical field [0001] The invention relates to the technical field of geothermal development and utilization, in particular to a mid-deep geothermal non-interference heating system with energy-saving intelligent control in the whole process. Background technique [0002] The medium-deep geothermal heating system uses medium-deep heat sources to provide heating heat to end users. Compared with conventional boiler heating, air source heat pump heating, and electric heating, its energy consumption cost is extremely low during operation, and it is green, economical and sustainable features. However, the mid-to-deep geothermal heating system involves the heat transfer performance of underground pipe heat exchangers, geothermal heat exchange, groundwater circulation, hot water grade improvement, heat supplement, hot water transportation, air conditioning and other technical links. The main equipment and facilities include geothermal wells , ground source side circulation pump, h...

Problems solved by technology

[0007] The current status quo is: people often only focus on the energy saving of local energy-consuming equipment, which will cause the situation of "blind men feeling the elephant".

That is, it is possible to save energy on some local energy-consuming equipment (such as: heat pump unit compressor), but at the same time cause the energy consumption of other energy-consuming equipment (such as: water pump or fan) to increase, so that the total energy consumption of the system not only does not decrease , but increased
