Abstract

The invention discloses a PLC-based ground source heat pump thermal response testing system, which realizes intuitive operation and real-time monitoring of the ground source heat pump response testing system through a PLC programmable controller and a WinCC man-machine interface in the system. The technical problem solved by the present invention is to carry out real-time remote monitoring of the testing and experimental process of the ground source heat pump. The PLC-based ground source heat pump thermal response testing system disclosed in the present invention can not only be applied to the actual measurement of engineering, but also can be used to measure the thermal properties of soil. The parameters are researched, and the tester introduces PLC programmable controller and WinCC module to realize the remote monitoring of the measurement and experiment status. The tester has compact structure, wide range of test depth, high degree of visualization, convenient operation, safe use and high test accuracy.

Description

[0001] technical field [0002] The invention relates to a soil thermophysical property testing system, in particular to a PLC-based ground source heat pump thermal response testing system. [0003] Background technique [0004] Ground source heat pump technology refers to the use of renewable surface heat energy existing in underground rock formations, such as low-grade heat energy in heat sources such as soil, groundwater, surface water or sewage, to achieve heating in winter, air conditioning in summer and hot water supply throughout the year. technology. Because of its advantages of greatly reducing the consumption of conventional energy, low operating costs, and no pollution, it is being widely used in our country. The soil thermal conductivity is an important parameter in the design of ground source heat pumps, which has a great impact on the performance and economy of the ground source heat pump system. If the thermal conductivity of the soil is inaccurate, the desi...
