Heat pumps are also suitable for cooling the temperature of buildings in summer. In this process, the process process in the device is reversed and the heat is "pumped" out of the building into the surrounding area. The type of collector is decisive here. While an air-source heat pump is unsuitable due to the high ambient temperature at the same time, the groundwater heat pump can fall back on the always cool groundwater and cause a significant cooling effect for the interiors.
The limiting factor is usually the type of transmission surfaces. If the "cold" is to be emitted via the floor heating, for example, a sensor must be used to ensure that condensation does not occur in the floor structure due to the low flow temperature. In this respect, heat pumps can never replace air conditioning systems or provide comparable performance. A distinction is made between active and passive cooling with heat pumps, see encyclopedia articles on heat pumps, active cooling and heat pumps, passive cooling.
