Abstract

The invention discloses a data heat transfer model-based testing device and a testing method thereof. The device consists of a water tank, a thermostatic heating pipe, a water pump, a valve, a thermometer, a temperature sensor, a pressure gauge, a flow meter, an electric power sensor, a U-shaped embedded pipe, a data processor and a control switch. The thermal physical parameters of tested rock soil can be obtained according to the water temperature change values of an inlet and an outlet of the U-shaped embedded pipe, flow and pressure values of water and original soil temperature value acquired by the temperature sensor through a one-dimensional unsteady state value model by adopting a comprehensive calculation method.

Description

technical field [0001] The invention patent belongs to the field of construction survey and construction, and particularly relates to a testing device and testing method for geotechnical thermophysical parameter testing for ground source heat pump applications. Background technique [0002] The ground source heat pump system is a new form of air conditioning and heating using renewable shallow geothermal energy. The ground source heat pump system utilizes the characteristics of absorbing and discharging heat to the soil and using the relatively stable ground temperature throughout the year to ensure the efficient operation of the unit, thereby reducing the use of non-renewable energy and greenhouse gas emissions to achieve the purpose of energy saving and emission reduction. Ground source heat pump air conditioners are growing at a rate of 20%-25% every year in my country, and the scale has shifted from small and medium-sized buildings to large buildings, building complexes,...
