DesignBuilder provides 3 types of ground heat exchanger:
The Drop down list on the DesignBuilder ground heat exchanger dialog allows you to select the ground heat exchanger type.
The Ground Heat Exchanger components do not offer an autosize option and so flow rates and other sizing information must be obtained using the method described in Step 6 of the GSHP Case Study. An inaccurately sized heat exchanger component can cause GSHP systems to generate inaccurate results.
Tip: You are advised to work through the GSHP Case Study before attempting to model these systems for the first time.
