Abstract

The invention discloses a device and a method for monitoring property and biological activity of ground source heat pump surrounding soil. The device comprises cable conductors and an outer sleeve, wherein a soil water content monitoring module, a soil temperature monitoring module and a soil biological activity detection module are arranged in the outer sleeve; and the soil water content monitoring module, the soil temperature monitoring module and the soil biological activity detection module are connected with an outside control system through the cable conductors. According to the device disclosed by the invention, the soil water content is collected by the soil water content monitoring module, the soil temperature is collected by the soil temperature monitoring module, and the soil biological activity is collected by the soil biological activity detection module. The device disclosed by the invention is capable of respectively monitoring the temperature, soil water content and biological activity of the ground source heat pump surrounding soil in real time, evaluating the performance of the ground source heat pump surrounding soil according to the three indexes and further researching a solution for improving the operating performance of the ground source heat pump.

Description

technical field [0001] The invention belongs to the technical field of environmental protection energy, and relates to a soil performance detection device and method, in particular to a device and method for real-time monitoring of soil performance around a ground source heat pump. Background technique [0002] In today's energy shortage and increasingly serious environmental pollution, ground source heat pumps have been vigorously promoted as an efficient and pollution-free new energy utilization technology. However, the current ground source heat pump has the problems of short life cycle, poor cooling or heating effect, and cannot fully exert its efficacy. [0003] The current researches attribute the decline of ground source heat pump operation performance to the problem of soil heat imbalance, which is mainly reflected in the change of the original soil temperature. It is necessary to monitor the soil temperature around the ground source heat pump in real time. [0004...

AI Technical Summary

Problems solved by technology

[0005] There are a large number of microorganisms in the soil. When the ground source heat pump is running, the temperature of the soil around the ground source heat pump will drop or rise sharply, resulting in the death of a large number of microorganisms, which not only affects the physical and mechanical properties of the soil, but also greatly reduces Heat exchange efficiency of source heat pump

Many scholars attribute the failure of ground source heat pumps to the imbalance of soil thermal power, without considering the damage caused by soil temperature changes to microorganisms.

[0006] In summary, there is no real-time monitoring device for the soil around the ground source heat pump (effective monitoring of the physical properties and biological activity of the soil around the ground source heat pump)
