Abstract

The invention relates to a well-pump-less geothermal water heating method and system. The well-pumpless geothermal water heating method comprises the following steps: sufficiently mixing geothermal water and backwater of a heating system, and then transporting the mixture of the geothermal water and the backwater into the heating system for heating. The system comprises a jet pump and a heating system, wherein the jet pump is arranged in a deep geothermal water well, and is used for pumping the geothermal water; the backwater of the heating system is used as a jet flow medium of the jet pump and is connected with a jet flow medium inlet of the jet pump via a jet flow medium water inlet pipeline; the jet flow medium water inlet pipeline is provided with a circulating pump used for pressurizing the backwater of the heating system; and a mixed medium outlet of the jet pump is connected with a water inlet pipeline of the heating system. According to the well-pump-less geothermal water heating method and system, the backwater of the heating system can be efficiently utilized; the water resource consumption caused by directly discharging the backwater of the heating system is reduced, and heat energy in the backwater of the heating system can be efficiently utilized; and the aim of saving electricity and water to the maximum extent under the condition of meeting the technological parameters of the heat energy and the circulating water quantity required by the heating system can be realized.

Description

technical field

[0001] The invention relates to a method and system for utilizing geothermal water, in particular to a method for utilizing geothermal water for heating and a system suitable for the method. Background technique

[0002] Geothermal water has dual attributes of water resources and mineral resources, and is listed as one of the renewable energy sources encouraged and supported in the Renewable Energy Law. Due to its clean, cheap and renewable characteristics, it is widely used in building heating and air conditioning.

[0003] The existing geothermal water heating technology is that the geothermal water is pumped out by a hot water well pump and directly enters the user's heating system (geothermal coil system, radiator system or fan coil system of central air conditioning), and passes through the heating system. The dissipated water is discharged directly into the sewer.

[0004] The existing geothermal water heating technology mainly has the following defic...
