The present invention relates to a system solution for energy using heat pumps with energy accumulation on both sides of the heat pump, and adsorption and desorption of energy to multiple sources. On the hot side is used as accumulators primarily treasury accumulator, secondary accumulate in the equalization tank. In addition, are pools used to the accumulation of heat so that the energy can accumulate at nights when energy price (system price) is low and is used during times of day when the system price is high.

Energy recovering is used to extract most of the energy from emissions in buildings or industrial processes. It could be from the emission of air, gas, liquid or water., Energy recovering are for example done from the exhaust air from large buildings. It also recovers some energy from waste water from buildings and industrial processes. In today's world, there is a strong focus on energy efficiency, the use of energy from non-renewable and renewable energy sources and recycling.

The energy recovered in such a way will in most cases may be immediately used for heating the incoming fresh air or water storage of energy is difficult and uncommon. For example, the recovery of energy from swimming pools at night will be greater than the consumption. Dehumidification nighttime will produce more power than is needed and this system solution enables recovery of this energy accumulator for use as needed. This is depicted in Figure 5 the molier diagram. For example, a indoor swimming poo! having 60% RH humidity that must be dehumidified to avoid damage to the building. Air from the indoor swimming pool is transported through a ventilation unit which has dehumidifier that cools the air from (a) to point (b) which is the dew point. Further cooling will abuse water from air until acceptable flow is precipitated point (c). 50% of the released energy from a - c will be used to heat the air to room temperature between step (c) and (d). Because of dehumidification, only a portion of the energy could be used to heat the air. (Dry air after dehumidification will not require more than 50% of the amount of energy in the dehumidification process.) Surplus energy that is released when dehumidification is accumulated in the accumulating tank and / or in swimming pools. Swimming pools with for example a volume of 800,000 I is heated 1 degree at night as a result of the accumulation. This is the energy which can be drawn out during the daytime when the demand is greater than the dehumidification then can deliver.

Furthermore, is so that the spot price of electricity can vary massively much of the day and year. This system solution allows magazines recovered energy so one can buy energy at night when it is cheap and use if in the day when demand is greatest and price highest, very central and good energy conservation.

The heating system is built as low-temperature 50/40°C which preheats the water consumption from 4°C to 50°C. This means that the use of low temperature is possible to meet the energy requirement of 100% after heat to the pool water, radiator heating and ventilation units and 85% pre-heating of consumption water.

The uptake of energy from multiple sources that accumulates in the buffer tanks then use of energy via heat pump buffer tank for heating that distributes to multiple

Excess heat can be distributed to neighboring buildings. The prior art in this area is known among other things from DE 102010023777 A1 where a heating system with a heat pump that uses accumulator tanks on the cold and hot side.

In JP 4084050A is a heat recovery system for use at low temperatures. This is done here using heat pumps and water with ice cubes circulating for recording low- temperature energy. Phase change between ice / water utilized by heat absorption. JP 2011027351 A, JP 4084050A and JP 6307655A has also some relevance to the prior art on the site.

It turns out when the traditional manner extracts energy from the exhaust air or water, there is more energy that can be utilized for use.

What is particularly achieved in terms of the prior art in this area is to be able to extract more energy by heat recovery of air and save it for use when the need is present and energy is expensive to buy. This happens after the air is dehumidified and that energy can be extracted.

This is achieved according to the invention in that a medium on the spot with the predetermined temperature Is circulated and recovers energy from the waste water from water in water treatment plants, dehumidificafion energy for outgoing air and from outgoing air by mechanical heat exchanger with the incoming air, after which energy is stored for a long time in the one larger volume of water and then heat is pumped to another medium on the side of higher temperature and buffered to a larger volume of liquid for subsequent use.

The invention is presented in the figures is the support for the understanding of the specification and the claims.

Figure la and b shows present complete solution. Figure 2 display unit solution for dehumidification. Figure 3 shows system solution for regular ventilation.

Figure 4 shows the basic principle of the invention. Figure 5 shows a molier diagram.

The basic principle seen most easily in Figure 4 as in the present example relates to an indoor swimming pool, but not limited thereto according to the invention. A heat pump 1 is provided with 1 st buffer tank 2 on the cold side and a 2 ^nd buffer tank 3 on the warm side. On the cold side energy obtained from multiple sources into a k- transport medium 8 that circulates energy of the 1st buffer tank 2. The air in the indoor swimming hall and other rooms are replaced and energy recovery in probably known manner via mechanical recovery. Sources where the cold side obtains energy from are the outgoing air through a 1st heat exchanger 4 which are placed after a traditional mechanical recovery unit 9 and extracts residua! energy in the air (+7 to +1 °C), from dehumidifying unit for outgoing air via a 2nd heat exchanger 5, from the water treatment plant for pool water via a 3rd heat exchanger 6 and waste water from showers and toilet facilities via a 4th heat exchanger 7. The function is based on the heat pump 1 cools down the 1 st buffer tank 2 with ice water (at least +0°C) _! which circulates through the heat exchangers 4,5,6 when doing recovery of energy.

The 2 ^nsS buffer tank 3 acts as a reservoir for energy quantities obtained from 1 st buffer tank 2 via the heat pump 1. From 2nd buffer tank 3 is retrieved energy using a v- transport medium 24 to more than 8th heat exchanger 20 heats the incoming air, water for radiators for heating rooms and heating of incoming fresh water to pools or to provide hot water.

Magazines energy is built up in the 2nd buffer 3 in the night and the day may be used, divided by the energy fluctuations in consumption.

This is one of the major differences to traditional recycling, where waste heat must be applied / used directly, or alternatively will not be the energy be utilized, and will be lost.

The present invention accumulates primarily heat recovered through the buffer tanks 2, 3, secondarily used equalization tanks and waste water tanks as buffers as needed. The pool volume is used therefore to the accumulation of energy as needed as previously mentioned.

At day mode will magazines amount of energy used to raise the temperature of ice water considerably. This results in greater cooling factor, which provides a greater amount of power output than the input power for operation of the compressor. The ice water have the temperature (from a minimum of -2°C and further upwards) which gives maximum absorption of energy from sources without freezing of ice stops the process.

The k~transport medium 8 ice water, also circulates through 1 st heat exchanger 4 which is placed after the exchanger 9 on exhaust air to ventilation units, as compared to the annual average temperature will be about +7°C. K-transport medium 8 is mixed with glycol about 30%.

In summer operation, the above 1 st heat exchanger 4 also could act as cooling coil of the system as icy water gets too high temperature

The hot side (the condenser side) of the heat pump 1 emits heat which is recovered from the above sources to a buffer tank which holds a maximum temperature of 55 ° C. Back up from after heat sources 10 such as electric boilers or far away produced heating starts first down at 45 ⁰ C. Figure 1 A and 1 B show the principle in relation to a more practical present-finding system. Figure 1 A shows a traditional indoor pool / swimming pool complex as there are many around the country. This is from Isbjornhallen in Hammerfest. Figure 1 A shows the plant at Isbjornhallen without the use of heat pump. And Figure 1 B with the use of heat pump. The lsbj0rnhal! is equipped with a small pool 1 1 which is small and has little depth and are suitable for children, and a large pool 12 which is more of the type of swim lanes, different depth of longitudinal and maybe tower on land plunge. Connected to the small and large pool 1 1 , 12, are two equalization vessels, a 1st equalization vessel 13 and a 2nd equalization vessel 14.

The pools have a k-supply 15 of colder water and v- supply 16 of warmer water mixed using a mixing valve 17. The mixing valve 17 creates a suitable temperature mixture of water to the pools 1 1 ,12 after the two water volumes are equalized via the two equalization tanks 13,14.

In Figure 1 are two buffer tanks 3' as the use of the invention in Figure 1 B at this facility may be used to 1 st buffer tank 2 on the cold side and 2nd buffer tank 3 at the hot side. The Isbjornhall is also equipped with a bleeder wafer tank 18 for water from the pools 1 1 ,12 and hot water tank 19 for heating the water, for example electric boilers 10.

Figure 1 B shows the Isbjornhall plant connected to the invention. The foregoing devices appear from this, but in addition the 1 ^st buffer tank 2 connected to the pump via a k~side heat exchanger 21 and the 2nd buffer tank 3 is connected to its side of the heat pump 1 via a v-side heat exchanger 22. The 1 st buffer tank 2 is also in connection with the bleeder water tank 18 via a bleeder water exchanger 23.

Figure 2 shows how the traditional recycling and recovery unit 9 obtains energy from the outgoing air and uses it to preheat the incoming cold air. It is also stated here that several of the 1 st heat exchanger 4 are placed in parallel with the outgoing air to extract the last bit of energy.

Figure 3 shows much the same as figure 2 only with the difference that the recovery unit 9 is a plate type heat exchanger in Figure 2 and in Figure 3 a rotary type.
