Abstract

The invention aims at providing a carbon dioxide ground source type geothermal system which saves energy and is environment-friendly, simple in structure and suitable for frost weather in north part. The carbon dioxide ground source type geothermal system comprises a carbon dioxide transcritical compressor, an oil separator, a coiler, a heat regenerator, an expansion valve, a U-shaped pipe and a gas-liquid separator; an outlet of the carbon dioxide transcritical compressor is connected with the oil separator, the oil separator is connected with the coiler, and the coiler is connected with the heat regenerator; one side of the heat regenerator is connected with the expansion valve and an inlet of the U-shaped pipe embedded in the ground, and the other side of the heat regenerator is connected with an output opening of the U-shaped pipe embedded in the ground and the gas-liquid separator; and the outlet of the gas-liquid separator is connected with the carbon dioxide transcritical compressor.

Description

technical field [0001] The invention belongs to the technical field of heating and cooling systems, in particular to a carbon dioxide ground source geothermal system. Background technique [0002] The soil source heat pump utilizes the characteristics of soil temperature stability throughout the year. In winter, the soil energy is used as a heat source for heat pump heating, that is, the heat energy in the ground energy that is higher than the ambient temperature is taken out for indoor heating. In summer, the soil energy is used as a cold source for air conditioning. , that is to take out the indoor heat energy and release it to the soil below the ambient temperature. Usually, the system needs to use water as the refrigerant to provide cooling and heat for users, which consumes a lot of water resources and consumes a lot of energy. Contents of the invention [0003] In order to overcome the defects of the prior art, the purpose of the present invention is to provide an e...
