Abstract

The invention discloses a heating and refrigerating system applied to a supergravity model test. A driving acquisition system is arranged outside a supergravity centrifuge, a multistage centrifugal pump is connected with a cooling circulating water machine, the cooling circulating water machine is connected to a rotary joint through a flow meter, and the multistage centrifugal pump is connected with the rotary joint; a temperature sensor is arranged in the cooling circulating water machine and is connected with a temperature data collector; the rotary joint is arranged on a main shaft base ofthe supergravity centrifuge, the rotary joint is connected with the temperature control system, and the temperature control system is arranged on a hanging basket of the supergravity centrifuge; and two flow dividers serve as an inlet side and an outlet side respectively, flow dividing ports of the flow dividers are connected to the two ends of an energy pile silicone tube, and the energy pile silicone tube is pre-buried in the energy pile to form an underground energy structure. According to the heating and refrigerating system, the multistage centrifugal pump is adopted, the driving acquisition system is arranged outside the supergravity centrifuge, the influence of supergravity on an experimental device is reduced, and a technical problem that only the same temperature load can be applied to a single model is solved by adopting the flow divider and a temperature control valve; and the stability and the accuracy of temperature measurement can be improved.

Description

technical field [0001] The invention relates to a heating and cooling system in a supergravity environment in civil engineering and ground source heat pump technology, in particular to a heating and cooling system used in a supergravity model test in a supergravity simulation experiment device. Background technique [0002] The energy underground structure combines civil engineering and ground source heat pump technology. It can not only use the bearing capacity of the underground structure, but also collect shallow geothermal energy for heating and cooling of buildings, infrastructure and various environments. It can save energy and reduce energy consumption. The advantages of carbon emissions have therefore attracted extensive attention from industry and academia. [0003] Affected by climate and seasonal changes, the temperature of shallow soil on the surface is constantly changing. Studies have shown that temperature changes may lead to a reduction in the bearing capacit...
