  In geothermal heat pumps, the heat exchange with ground is performed by the ground heat exchanger. In fact, the ground heat exchanger is installed to extract or inject the thermal energy from/to the earth. The borehole depth of this heat exchanger has a major effect on the system investment cost and operation; thus, this parameter must be computed with a high accuracy. There are various methods to compute the borehole depth of ground heat exchanger. The geothermal heat pump capacity and the regional soil characteristics are the main parameters which affect the borehole depth and size of the ground heat exchanger. In this paper, the important soil characteristics are first introduced. Then, the main five methods for computing the borehole depth of ground heat exchanger are investigated with their effective parameters. Finally, these methods are compared and their application priority is determined. Manuscript profile

  The pumping station is a collection of pumps, driving forces and auxiliary equipment e.g., collector system, power supply system, and control and protection systems. Small pumping stations are usually designed in the simplest possible way for the ease of operation of auxiliary equipment. However, as the capacity of the pumping station increases, the technical complexity and design of peripheral equipment increases, which requires its own design according to the conditions, type of work, and location of the project. The choice of the type of station building, the type and capacity of the main and reserve pumps, in accordance with the special conditions of each project are contingent upon the nature of the plan. This study evaluates the basics of designing pumping stations, taking into account the above-mentioned issues, focusing on the system of pumping and transferring water from Dasht Zozen to the central site of the water supply facilities of Sangan Industries.
