An air/water heat pump can use the outdoor air to heat up a home. The conversion of the outdoor air’s energy to residential heating occurs in three different circuits. In the brine circuit (1), free heat energy is retrieved from the surroundings and transported to the heat pump. The heat pump increases the retrieved heat’s low temperature to a high temperature in the refrigerant circuit, (2).
Control of JÄSPI Inverter Nordic The heat pump is controlled in various ways depending on your system. You control the heat pump via your indoor module JÄSPI Theowatti Air or control module JÄSPI_MCU40. See the relevant manual for more inform- ation.
Maintenance of JÄSPI Inverter Nordic Regular checks When your heat pump is located outdoors some external maintenance is required. NOTE Insufficient maintenance can cause serious damage to JÄSPI Inverter Nordic, which is not covered by the guarantee. Checking grilles and bottom panel on JÄSPI Inverter Nordic Regularly check throughout the year that the grille is not clogged by leaves, snow or anything else.

5 Glossary Additional heat The additional heat is the heat produced in addition to the heat supplied by the compressor in your heat pump. Additional heaters can be for ex- ample, immersion heater, electric heater, solar power system, gas/oil/pellet/wood burner or district heating. Ambient temperature sensor A sensor that is located outdoors on or close to the heat pump.
Condenser Heat exchanger where the hot gas state refrigerant condenses (cooled and becomes a liquid) and releases heat energy to the house heating and hot water systems. If a heat pump has COP of 5, this means that you only pay for a fifth of your heating demand.
Expansion valve Valve that reduces the pressure of the refrigerant, whereupon the temper- ature of the refrigerant drops. Expansion vessel Vessel with heating medium fluid with the task of equalising the pressure in the heating medium system. During heating operation, the fan transports energy from the ambient air to the heat pump.
Refrigerant Substance that circulates around a closed circuit in the heat pump and that, through pressure changes, evaporates and condenses. During evap- oration, the refrigerant absorbs heating energy and when condensing gives off heating energy. Return pipe The line in which the water is transported back to the heat pump from the house heating system (radiators/heating coils).
