GEOTHERMAL SEMINARS - WINTER CONFERENCE 

 

 

Seminar 8: Earth, Heat and Ice: Expanding the Effectiveness of Geothermal Systems Using Ice Storage

 at  – 

Hilton Orlando, LL, Orange B

 

Session Type: Seminar Program Track: Energy Storage and Grid Resiliency Program Level: Intermediate

Summary:
Ground source heat pumps (geothermal) are the most efficient form of electrified heating but are also the most expensive and require the most space. Through the application of ice storage, the capacity of geothermal systems to provide cooling and heating can be extended and the required size reduced. This seminar highlights systems that are both in use and in design that use ice storage in novel ways to expand system capacity, increase installed cost effectiveness and provide a wider operating envelope than they would otherwise have.

Seminar 37: Myth Buster: The Ground Heat Exchanger Needs to be Balanced?

  – 

Hilton Orlando, LL, Orange C

 

Session Type: Seminar Program Track: HVAC&R Systems and Equipment Program Level: Basic

Summary:
Busting the myth about ground heat exchange imbalance, starts with a grounded understanding of GHEX design fundamentals. Applying proven design methods to calculations and exploring risks that may arise in the future are key to designing a system intended to provide efficient operations over the full life of the building. This session starts with a review of proven design methods, identifies tradeoffs to be considered during design, and presents solutions applicable to hot or cold climates. Reviewing case studies and lessons learned based upon long-term operations confirms that with the right design these systems are an effective long-term strategy.

Committee Scope

TC 6.8 is concerned with all equipment and systems which collect, store and utilize geothermal energy or fluids for the purpose of heating and cooling, and with the development and application of heat pump systems and heat recovery by refrigeration cycles including system design, operation, and performance (product design of unitary heat pumps and equipment components is excluded).

Kirk T Mescher Innovation Award

 

Kirk T Mescher Award

This award is in memory of Kirk T Mescher, PE, an engineer who specialized in HVAC but whose real forte was innovation. Kirk’s design ideas are clever in and of themselves but the courage to implement them in projects and freely share the results underscores his exemplary service to our industry.  The award will be given in recognition of those who demonstrate or foster innovation, simplicity, and energy efficient designs for HVAC and GSHP systems.

This award is transitioning to the ASHRAE foundation for its administration.
