Abstract In active optical-electronic systems for stream research that regulate thermal-physical parameters of diagnosed stream volume, the controlled source of the heat flow can be acquired by radiation of high-power IR laser diodes into the void. In the current work the peculiarities of measurement of this radiation are considered, specified by its strong divergence. It is shown that the measurements can involve laser wattmeters IMO-4M with planar thermoelectric primary measuring transformers of the laser radiation with a flat receiving site provided.

Abstract. As a high efficiency, low consumption and clean energy, ground source heat pump technology has been pay more and more attention, the number of installation of system is growing rapidly. However, the use of geothermal resources is still extensive at this stage. Effective methods are pure in obtaining thermal physical parameters of geothermal wells around. In-situ thermal response testing is close to the real use of heat pumps, when injecting in or extracting heat from geothermal wells, the testing equipment will collect data, and then thermal physical parameters will be accurately calculate. This paper introduce a thermal response testing equipment, the equipment will add a constant cold or heat to geothermal well, circulating heat flow and pressure data is collected as well as temperature. And then thermal physical parameters of formation and heat exchanging performance are calculated.
