Ground Source Heat Pump
A Ground Source Heat Pump (GSHP) is a sustainable heating and cooling system that uses the earth's natural temperature to warm or cool buildings. Think of it like an underground temperature exchange system. Unlike traditional heating systems that burn fuel, these pumps move heat that already exists between the ground and buildings. They're becoming increasingly popular in green building projects and energy-efficient construction. You might also hear them called "geothermal heat pumps" or "earth-coupled heat pumps." The technology is similar to a regular air conditioner, but instead of exchanging heat with outside air, it works with the steady temperatures found underground.

Example Interview Questions
Senior Level Questions
Q: How would you approach sizing a ground source heat pump system for a large commercial building?
Expected Answer: A strong answer should cover assessing building heat loads, ground conditions, available space for ground loops, and cost considerations. They should mention the importance of proper calculations to avoid under or oversizing the system.
Q: What strategies would you use to optimize the efficiency of a GSHP system?
Expected Answer: Look for discussion of proper loop field design, optimal flow rates, correct system balance, and integration with building management systems. Should also mention monitoring and maintenance practices.
Mid Level Questions
Q: What are the different types of ground loop systems and when would you use each?
Expected Answer: Should explain vertical vs horizontal loops, closed vs open systems, and discuss site conditions that would favor each type. Understanding of space requirements and installation costs is important.
Q: How do you troubleshoot common GSHP system problems?
Expected Answer: Should demonstrate knowledge of typical issues like incorrect flow rates, air in the system, or improper pressure, and systematic approach to identifying and resolving problems.
Junior Level Questions
Q: Can you explain how a ground source heat pump works in simple terms?
Expected Answer: Should be able to describe the basic principle of heat exchange with the ground, the role of the heat pump, and the basic components of the system in non-technical language.
Q: What safety considerations are important when working with GSHP systems?
Expected Answer: Should mention electrical safety, pressure testing, proper handling of heat transfer fluids, and importance of following installation guidelines and local codes.
