چکیده

Abstract The outdoor pipe coil frosting of air source heat pump seriously affects the working efficiency equipment. Therefore, a new frost detection algorithm is proposed to optimize defrosting process. First all, image difference introduced remove interference factors in image. Then, brightness correction and denoising are carried out. Finally, combined with processing algorithms such as contour Otsu multi-threshold segmentation achieve regional detection, accuracy further improved. experimental results show that, compared existing methods, not only improves but also has better treatment effect on light changes frost. added Experimental that intelligent than current strategies.

Research on Ground Source Heat Pump Design

One of world’s largest uses of energy is the heating and cooling of buildings. Ground Source Heat Pumps (GSHP) provide a more energy efficient way to meet building energy needs than conventional alternatives. At a relatively shallow depth, the ground temperature is nearly constant year round providing a reliable heat source or sink for the operation of a heat pump. The design of such systems is...
