5. Coupling heat pumps to the cold source (installation rules)
In the case of heat pumps, the cold source is the external source. There are three main cases: ground, water and air, as already mentioned.
5.1 Ground coupling
This solution may require an intermediate brine circuit between the heat pump and the ground.
The main advantage of soil as a heat source is the stability of its temperature throughout the year, as soon as you reach a depth of a few tens of centimetres, as shown in figure 30 : while at the soil surface, the amplitude of temperature oscillations follows those of the air, damping is very rapid as a function of depth, and from...
