SET25 EVI multi-function heat pump heats the heat accumulator and at the same time load the cold accumulator. An excellent heat pump when heat and cold are needed in the same building: e.g.: restaurant, hotel, farm, production plant, villa, off-greed site.
Applications:
1. Energy saving project – electric heating 3000L with electric storage tank 8 – 12kw
2. Solar power project
3. Exchange electricity, night electricity project
4. Change of heating method
5. Geothermal heat renovation
6. Cooling and heating system
7. Exchange electricity, night electricity project
8. Hybrid heating
Operation presentation:
1. Energy saving project – heating system – electric heating 3000L.
Why a 25kW heat pump? A 25kW heat pump charges in a few hours using inexpensive night electricity. For example: 4 hours of night electricity produces 100kW of heat output using 17kw of night electricity or exchange electricity. If the building has cooling equipment and/or a cold or freezer room, a separate heat source is not even needed.
2. Solar PV target – solar PV 5 – 10kw Why a 25kW heat pump? A 25kW heat pump charges the energy storage in a few hours using solar power. For example: 4 hours of solar power produces 100kW of thermal power (100kw / 24 hours = 4kw of constant thermal power per hour during the day) using 17kw of solar power. If the building has cooling equipment and/or a cold room, a separate heat source is not even needed.
3. Geothermal renovation – target – geothermal 8kw
Geothermal renovation - SET25 EVI Nordic - heat pump for the renovation of a geothermal system with freezing problems. The geothermal well cools down over the years, especially if the energy well is too small. SET25 EVI Nordic - the geothermal heat pump does not turn off even if the collector fluid is strongly below zero. Short-term heat pump operation enables the recovery of the heat recovery circuit during a long break and for heating the active heat recovery circuit in the summer. Further savings are created by using inexpensive night electricity, e.g.: 4 hours of night electricity produces 100kW of heating power.
Operating principle:
1. Using the heat accumulator: the multi-function heat pump heats the heat accumulator and uses it to distribute the heat used, such as: underfloor heating, radiators, domestic water, etc.
2. Using the cold accumulator: the multi-function heat pump charges the cold accumulator with cold and uses it to distribute the cold, such as: house cooling, cold room, freezer, refrigeration, etc.
3. Heat sources. If the use of the accumulators is in balance, an external heat source is not needed. When the cold accumulator is at its maximum, a warm heat source. Heat sources, e.g.: geothermal heat, exhaust air, outdoor air, sewer, fireplace, LTO - separately or all together. The battery's power sources are used at different times than the heat pump itself. The most efficient solar-air water heating panel. The way a solar and air water heating panel works: A. the sun heats the liquid in the panel B. air is blown through the casing and the air heats the liquid in the panel The solar-air water heating panel works as a heat pump circuit for a heat pump, if solar energy is available it heats the heat battery directly without using a heat pump. We offer an external heat source option depending on the project.
