Geothermal Management Remote System

Geothermal Management Remote SystemUsing soil as a heat source or sink for buried pipe heat exchangers to provide heating and cooling to buildings The thermal conductivity of soil is an important parameter in the design of buried pipe heat exchangers Long term and reliable monitoring of ground temperature is particularly important. When measuring the soil thermal conductivity on site, the testing time should be long enough. The temperature of the fluid inlet and outlet and different depths after the working conditions are stable during testing will affect the accuracy of the test results. Therefore, the design of buried temperature measurement cables is particularly important.

The ground source heat pump temperature field measurement and control system launched by Beijing Hongou Chengyun Instrument Equipment Co., Ltd. adopts advanced ARM technology in hardware; The upper computer software is designed using programming language technology, which is user-friendly, intuitive and clear; The temperature sensor is directly encapsulated inside the cable and packaged according to the distance required by the customer. At present, this system is widely used in ground source heat pump buried pipes, ground source heat pump temperature field detection, ground source heat pump buried heat exchange wells, ground source heat pump vertical shafts, and ground source heat pump temperature field systems for ground temperature monitoring. The reliability and stability of this system have been verified in many projects and have achieved good results.

Monitoring method of soil temperature in ground source heat pump diagnosis:
In order to achieve the diagnosis of ground source heat pump systems, it is necessary to first establish reasonable standards to ensure the normal operation of the system. In the design phase of the system, the initial value of underground soil temperature is an important reference parameter, and it is also a parameter that may change during the operation of the system. If after one or several air conditioning heating cycles (usually one air conditioning heating cycle is one year), the system's heat extraction and release are severely unbalanced, the initial temperature will have a significant change, which will greatly reduce the system's operating efficiency. So the design uses the soil temperature change curve as the standard for diagnosing whether the system is normal.
First pairGeothermal Management Remote SystemThe controlled building undergoes annual dynamic energy consumption analysis, which involves inputting the building's conditions, including its geographical location, orientation, external dimensions, enclosure structure materials, and room functions, to calculate the annual heating and cooling load of the area. Based on this load, we select the appropriate system configuration, including the number of buried pipes and necessary auxiliary heating and cooling sources, and dynamically simulate the changes in soil temperature during the operation of the ground source heat pump reinforcement system to obtain the initial soil temperature standard curve. Adopting an operation plan that meets the basic equilibrium requirements of soil temperature, while the system monitors the changes in soil temperature in real time, that is, relying on temperature sensors buried underground to monitor the soil temperature, and transmitting the measured temperature to the ground source heat pump system.
