The type of microscope depends upon the type of sample created.
For observing a sample just to check out its presence of any substance, you can use a simple microscope, and to observe a sample by its morphological features with varying objective lens, you can use compound microscope. To study deep details of the sample, a microscope of high magnifying power like electron microscope can be used.
A ground source heat pump takes advantage of the naturally occurring difference between the above-ground air temperature and the subsurface soil temperature to move heat in support of end uses such as space heating, space cooling (air conditioning), and even water heating. A ground source or geo exchange system consists of a heat pump connected to a series of buried pipes. One can install the pipes either in horizontal trenches just below the ground surface or in vertical boreholes that go several hundred feet below ground. The heat pump circulates a heat-conveying fluid, sometimes water, through the pipes to move heat from point to point.
this system works during the winter due to it being a sub-ground energy source.
