STATE OF THE ART

In hot climates air conditioners (coolers) are most often electric powered machines. They consume significant amounts of electricity. At the hottest moments in summer power grids can get overloaded. There are several technologies in the market for peak load shaving. Amongst them ice energy. They produce on site ice during the night and during the day they use the sored cold to cool the building. Whatever cooling technology that is used, they remain large electricity consumers. There are no common technologies in the market today that harvest the almost infinite natural source of cold: deep ocean or deep sea cold. Further in this filing ocean also means sea.

SUMMARY OF THE INVENTION

The invention relates to methods and systems to provide cooling, more in particular (cold) liquid, suitable for cooling appliances; and related controllers, measurement systems suitable therefore, whereby large (artificial or natural) reservoirs of cold liquid (like the sea, preferably deep sea) is exploited.

The invention therefore provides arrangements (and uses thereof), including such large reservoirs and related (where suitable thermal isolated) pipes to connect to these systems are also provided.

The invention takes into account the entire ecosystem, including the electricity grid (which may include renewable energy), by describing various operating methods, resulting in a smarter peak load shaving.

In a particular embodiment these methods by branching off from said heat exchanger ensure that the temperature of the liquid released on a first (cold) side by said heat exchanger does not exceed a predetermined maximum temperature(to protect life in the reservoir wherein it is disposed).

DETAILED DESCRIPTION OF THE INVENTION

In a first embodiment of this invention a pipe system with at least two canals installed in the ocean and at least one pump. The deepest canals go so low that they stretch out as deep as possible and, if feasible, below the so called thermocline. Thermocline is that region in the ocean or the sea where the temperature of the water decreases until it becomes stable at a cold temperature. The thermocline region is very much depending on the local geography and climate. A most common figure is that at 1000 meters below sea level the temperature stabilizes around 4°C. The cold water is pumped up towards the surface. At least one heat exchange circuit exchanges cold with the hot side of a cold network. As a result, the pumped up cold water is heated. Now it is returned back to the ocean or the sea through the second canal. As surface bound canals and depth bound canals are communicating vessels there is not much energy needed for the pumping. As the pumps for the pipe system and the pumps for the cold network only consume a fraction of the electricity consumed by traditional electric driven air conditioners the energy savings are tremendous.

In a second embodiment of this invention the surface bound canal is partially or totally thermal isolated so that as much cold as possible is preserved until it reaches the surface.

Therefore in accordance with this embodiment the system (10) (Figure 1) to provide (cold) liquid (suitable for cooling appliances (100)), comprises at least partially thermal isolated first pipe (20) connectable to said (huge) (cold) liquid reservoir.

In a third embodiment of this invention, the deepest canal through which water is pumped up towards the surface is equipped with at least one appropriate filter at the canal entry points to avoid as much as possible that deep ocean life is pumped up towards the surface. The filters can be equipped with fixed cleaning devices and or can be unmounted and mounted so that is possible to surface them for cleaning and or maintenance. In order to avoid unfiltered water to be pumped up when a filter is unmounted, one or more vanes can be installed that shut off the canal entry points or one or more lids can be temporary mounted when a filter is unmounted.

In a fourth embodiment of this invention, the exits of the depth bound canals are equipped with one or more temperature sensors and or separate temperature sensors are installed at the depth of the exits. At least one electronic controller circuit measures the water temperature at the depth of the exits. It can also measure the temperature of the pumped water at the exit. The flow in the heat exchanger circuits, as mentioned above, is regulated so that the pumped down water in the depth bound canals at the exits has the same temperature than the surrounding ocean water. This to avoid thermal chock for deep ocean life around the exit.

In a fifth embodiment of this invention one or more vanes are installed at different depths of the depth bound canals and they are equipped with sensors as described above. This allows the depth bound water to be dumped at different depths. In a sixth embodiment of this invention the canals are equipped with a flexible hinge near the surface and or can be disconnected near the surface. The pipe system further is equipped with appropriate devices so that it can be lifted towards the surface for maintenance and or repair.

In a seventh embodiment of this invention the pipe system is equipped with at least one thermal buffer so that is possible to pump up and store cold water during the night and thus reduce peak load and or use renewable energy when available.

In accordance with this embodiment the system (Figure 2), further comprising a liquid (temporally) storage capacity (70), arranged for receiving said (pumped) (cold) liquid and for further providing its storage liquid to said heat exchanger (for instance by use of a further pump (not shown)).

In an eight embodiment of this invention the pumped up cold water is run through a heat exchanger at the hot side of at least one chiller. The cold side of the chiller thus can produce cooling liquid below the temperature of the pumped up ocean water. This can be used for applications that require temperatures below the temperature of the pumped up ocean water and/or it allows to reduce the dimensions of the cold network. It further can be equipped with at least one thermal buffer as said in embodiment seven so that it is possible to reduce peak load and or use renewable energy when available.

In accordance with this embodiment of the invention the system (Figure 3), further comprising means (80) (e.g. a chiller) for cooling liquid, arranged for receiving said (pumped) (cold) liquid and for further providing its further cooled (same or other) liquid to said heat exchanger directly or indirectly via said liquid (temporally) storage capacity (for instance by use of a further pump (not shown) and/or bypasses (not shown)).

Generally speaking the invention provides one or more of the following:

1. A pipe system with at least two canals and at least one heat exchange circuit of which the surface bound canals reach as deep as possible and if feasible stretch beneath the thermocline region. 2. A pipe system as described of which the surface bound canals are partially or totally thermal isolated.

At least one deep ocean life filter at the suction end of the surface bound canals as described. The filters can be equipped with a cleaning mechanism and or can be mounted unmounted. One or more vanes and or temporary lids can be installed.

4. A pipe system as described above that are equipped with at least one temperature sensor and at least one electronic controller circuit to regulate the flow in the heat exchange circuits as mentioned above.

5. A pipe system described above of which the depth bound canals are equipped with one or more vanes at different depths.

6. A pipe system that is equipped with one or more hinges near the surface and or can be disconnected near the surface and devices to surface.

7. A pipe system with at least one thermal buffer.

8. A pipe system that is equipped with at least one chiller and optional one or more dedicated thermal buffers.

In the invention as described above, liquid storage capacity as provided by containers are useful in certain embodiments, especially those with thermal isolation characteristics. Below such thermal containers are described, including a way of construction those.

METHOD AND EQUIPMENT FOR THE CONSTRUCTION OF THERMAL CONTAINERS

STATE OF THE ART

As more renewable energy sources, mainly electric, are connected to the grid the need to match offer & demand grows increasingly. This is in general referred to as grid balancing. Most solutions available today are on or another form of electric batteries. However electric batteries are rather expensive and have limited lifetime. Another approach to store renewable electricity is to convert it first into another kind of energy like for example heat or cold or hydrogen. There are already heat batteries that are capable of storing heat over_the_seasons so that it can be used during winter capable to store heat for around 1000 homes. Such a company is Ecovat. Ecovat builds concrete thermal containers using mainly traditional construction methods. Also cold buffers exist that produce and store cold during the night to be used during the day. Such a company is Ice Energy. It puts modular water buckets on buildings and freezes the water during the night, during the days it blows the hot air of hvac installations over the ice to cool the air.

This invention differs from any existing thermal storage solution today: in storage capacity, in used materials, in construction method, in speed of construction, in functionality and in production cost.

The thermal storage capacity is that big that, for example, it can store all the waste steam condensation heat that is harvested of a nuclear reactor over two seasons. It can entirely replace the cooling tower in any power plant. In principle there is no practical limit to the size as long as geographical conditions are suitable.

The thermal container is essentially a tremendous cylindrical steel vessel with a slightly smaller cylindrical steel vessel inside and between the two vessels thermal insulation materials. The dimensions for such over_the_seasons thermal container for a nuclear reactor are a cylinder with a diameter and height of order 175 meters.

The used materials are mainly steel and thermal insulation materials. Steel is chosen as it is very cheap considering tension strength what is required to withstand hydrostatical pressure, segments can be very precise preformed upfront, segments can be easily transported, segments can be easily welded onsite and it can be very well treated against corrosion for very long time.

The underground surrounding the construction site is frozen before the actual construction. The construction method is that the vessels are constructed above ground ring by ring from preformed segments that are welded together on site. A robot can be used for welding. During the construction the already finished rings are suspended all the time. In the lowest rings rotating digging equipment digs the pit out and the debris is evacuated via a vertical central shaft. As the pit gets deeper the suspended construction is lowered until it reaches the required depth. As this method requires no long curing time and as digging equipment and debris evacuation equipment can have significant capacity the construction time can be very short.

All above combined make that it is a very cheap method of construction.

Another feature is that this construction method requires very few people working inside the pit.

This invention is a novel method and equipment for the construction of thermal containers.

In a first embodiment of this invention a geographic underground map is drawn of the site and the surroundings of the thermal container. Then, considering further embodiments and depending on the geographic underground map, multiple bore holes and bore depths are selected and created. Heat exchanger tubes are inserted and connected to a chiller or alike. The direct function is to freeze parts or the entire the underground of the construction site. The targeted function is to avoid underground water penetrating the construction pit during construction and to avoid muddy underground while digging the pit out and or to avoid lifting of the thermal container once one or two rings are totally sealed with a bottom. Some or all heat exchanger tubes might be temporarily or permanent disconnected and or shut off during the construction of the thermal tank.

In another embodiment his invention in the center of the construction site a deep hole might be bored to a depth surpassing the depth of the bottom of foundation of the thermal container. Next step is to insert a solid axle, rod or tube, in the whole. It is important to use a drilling method that bores extremely vertical as later in this invention we will use gravity to construct position the thermal container. Another way to obtain good verticality is to drill a large hole up to the depth of the foundation of the thermal container and then use gravity to align the bore, optional some guising equipment, that matches the dimension of the axle. Another way to obtain good verticality is to drill a large hole up to the requited depth and then use gravity to position the axle and then fill up the remaining space in the whole with filling material like for example concrete up to the bottom of the foundation of the container.

In a next embodiment, above ground a crane_scaffolding_construction fixes the position of the axle at the top. This crane_scaffolding construction has the form of a downwards turned U to allow above ground construction of the rings of the vessels or any other form that is suitable. The vertical axle fixed on top and bottom now will be used in combination with gravity and optional one or more axle_to_inner_skin_positioners anc| or one or more central_shaft_to_inner skin_positioners to position the rings of thermal container centric around the axle.

In a next embodiment of this invention a base_plate_construction is mounted around the axle. This base_plate_construction can be permanent and or can be removed after construction of the thermal container. This base_plate_construction can have multiple functions as described below but is not limited to described functions.

• mounting of one or more vertical debris removing chains

• mounting of one or more temporary lift shafts

• mounting of one or more liquids intrusion suction pipes

• mounting of one or more utilities supply channels

• fixation of one or more base_plate_to_inner skin_positioners to position the rings of thermal container centric around the base_plate_construction and thus in second order centric around the axle. These base_plate_to_inner skin_positioners can be permanent and or can be removed after construction of the thermal container.

• fixation and thus positioning a central_shaft_construction. This central_shaft_construction can be permanent and or can be removed after construction of the thermal container.

• mounting an inner guide rail for rotating_digging_beam_equipment

• mounting of an umbrella The crane_scaffolding construction might during construction, especially during lowering down, permanently or periodically lift the central shaft construction and the base plate. If this method is used there is no real need for a central axle. In the further text we will suppose a central axle present. If no central axle is used it is to be understood that the suspended base_plate_construction acts also as a central axle.

In a next embodiment around the outer vessel multiple hinge_crane_constructions are positioned and hankered. These hinge_crane constructions have the form of a downwards turned L to allow above ground construction of the thermal container rings or any other form that is suitable. The end of the lifting cables of the hinge_constructions are fixed to the first lower rings of the outer vessel and or to the first lower rings of the inner vessel and or to both first rings. As construction advances they can be also fixed to higher rings.

In a next embodiment of this invention two or more segments of the first ring of the vessels of the thermal container are positioned on the ground surface centric around the center axle and welded together. For welding a welding scaffolding_welding_robot can be used that hangs over the upper horizontal edge of one or more ring segments and or has platforms for workers. Welds and all other surfaces receive durable anti-corrosive treatment. Once two or more sections are welded they can be suspended and welded together. Finally, the first lower rings of both vessels are all welded together and are in suspension. Now, an outer guide rail is mounted horizontal at the inside of the first rings of the inner vessel. Now, various sensor shafts can be mounted on the surfaces of the rings.

In a next embodiment of this invention at least one type of insulation material is inserted in the space between the first rings of both vessels. When is use, as the inner vessel will dilate more than the outer vessel it is possible to use partly or totally compressible insulation material.

In a next embodiment of this invention, cables are mounted from the inner shell towards the base_plate_construction. These cables are mounted with hinges so that they can rotate along the center axle of the cable. This allows to roll triangular shaped sails around the cables. By rolling or unrolling all sails a kind of retractable umbrella is created. In a next embodiment of this invention one or more beams are mounted between the outer guide rail and the inner guide rail. On these beams one or more excavation tools are mounted and one or more debris removal chains. These beams are equipped with one or more drive installations so that they can rotate around the central base_plate and thus can dig out the pit.

In a next embodiment of this invention one or more movable heat exchanger circuits are mounted inside the inner vessel. This allows to exchange heat at various level inside the thermal container.

In a next embodiment of this invention one or more movable heat suction heads are mounted inside the inner vessel. This allows to extract and or inject water at various level inside the thermal container.

In a next embodiment of this invention the thermal container remains partially above ground.

In a next embodiment of this invention one or more above embodiments can realize their function by combining two or more subassemblies.

In a next embodiment of this invention two or more of above embodiments can be totally and or partially combined.

In a next embodiment of this invention some or all parts of above embodiments can be mounted and dismounted so they can be easily transported with standardize transport devices such as for example 40 and or 20 foot containers.

In a next embodiment of this invention, one or more waste heat exchanger circuits of industrial processes are integrated with one or more thermal networks and or one or more thermal containers. By monitoring the amount of recycled heat that is harvested, stored and distributed as useful thermal energy it is possible to claim C02 emission rights.

Generally speaking the invention, which can be used in the pipe system described above provides one or more of the following: 1. An over_the_seasons thermal container constructed suspended from ground surface level towards underground comprising two metal shells with thermal insulation in between.

2. A base_plate_construction for a thermal container.

3. A rotating_digging_beam with one or more rotating excavation wheels and one or more debris removal bands for the construction of a thermal container.

4. A movable heat exchanger circuit for a thermal container.

5. A movable suction head for a thermal container.

6. A scaffolding_welding_robot for the construction of a thermal container.

7. A sectional retractable umbrella of the construction of a thermal container.

8. Waste heat harvesting equipment integrated into thermal network and or thermal containers.

In summary this part of the invention is a method and equipment for the construction of thermal containers. An over_the_seasons thermal container constructed suspended from ground surface level towards underground comprising two metal shells with thermal insulation in between.
