The heat pump air unit WP SAT 15 from ratiotherm

Air heat pump as a supplement

In order to operate a heat pump as effectively as possible, a reliable source of environmental energy is essential to ensure the heat supply for the building. With our WP SAT brine-air outdoor unit, a brine heat pump, which is actually supplied by geothermal energy, can tap into air as an additional source. The additional module allows the energy source air to be used as a backup or to optimize efficiency. Especially in the summer months, the temperature of the air is higher than that of the brine, thus enabling a significant increase in COP. This is particularly interesting for use in combination with PVT collectors, as there are weather conditions in which PVT collectors can harvest very little environmental heat. To avoid heating element operation in this case, the heat pump can continue to use environmental heat efficiently by switching to the WP SAT air unit. Of course, the WP SAT can also be used as the sole energy source and cascaded for more power if necessary.

The WP SAT can also be used wherever probe fields or ground collectors cannot be made larger or where a larger collector area is not feasible for cost reasons. Even if geothermal energy is not available or only available to a limited extent in existing systems for any reason, a WP SAT can be retrofitted. The WP SAT is 100% compatible with all ratiotherm geothermal heat pumps. If necessary, the device can also be combined with third-party products using an external control unit.
