A ground source heat pump (GSHP) system uses the earth as a heat source in the winter and a heat sink in the summer. In the winter, the GSHP system extracts heat from the ground and transfers it to the building. In the summer, the GSHP system reverses the process, extracting heat from the building and transferring it to the ground. The GSHP system consists of three main components: a ground loop, a heat pump, and a distribution system.
The ground loop is a network of underground pipes that circulate a water/antifreeze mixture. The ground loop is buried in the ground next to the building. The heat pump is located inside the building. The distribution system distributes the heat from the heat pump to the different rooms in the building.
In the winter, the ground loop absorbs heat from the ground and transfers it to the heat pump. The heat pump then compressed the heat, which increases the temperature of the heat. The hot air from the heat pump is then distributed to the different rooms in the building through the distribution system.
In the summer, the process is reversed. The heat pump extracts heat from the building and transfers it to the ground loop. The ground loop then dissipates the heat into the ground.
