Ground Heat Recovery for Radiant Floor Heating
Application ID: 18529
Geothermal heating is an environmentally friendly and energy-efficient method to supply modern and well insulated houses with heat. Heat exchangers placed at a sufficient depth in the ground below the house utilize subsurface heat, where temperatures are almost constant throughout the year.
The Heat Recovery System for a Geothermal Heat Pump app studies different pipe configurations of a ground heat exchanger. It provides information on the performance of ground-coupled heat exchangers for different specifications (depth, pattern, pipes configuration, and heating conditions); temperature conditions; soil thermal conductivity; and temperature gradient.
The heater can also be turned off if the daily heat demand is achieved, and then turned on again after 24 hours. The temperature at the pipe's outlet can be controlled and compared to the minimum temperature required in the heat exchanger specifications.
This application example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
