Definitions
- This invention relates to a plant for production of hot water to one or more recipients , the plant comprising means for evaporating a refrigerant, a compressor for compressing the refrigerant whereupon the temperature thereof is in creased, a condenser for emitting the stored heat in said refrigerant to a water supply network connectable to the plant , as well as means for operating the compressor.
- heat pumps For the production of hot water in, for instance , households/industrial plants , for heating of locals and/or tap water, heat pumps of different types are used in an increasing extent , which achieve to transfer heat from a cold area to an already warmer area .
- each household has an own heat pump and these may vary a lot regarding seize and type depending on application, more precisely the seize of the local and the amount of tapped off hot water .
- common for heat pumps is that a refrigerant is circulated in a closed circuit in order to transfer heat from a cold source in the geosphere, suitable for the application, to the hot water system of the household.
- the refrigerant is evaporated in a low pressure side of said circuit , either by being exposed directly for geothermal heat , water heat, etc .
- the electric energy is created by means of, for instance , a wind power plant or a water power plant , in which so-called flowing energy (wind energy, water energy) is converted into a mechanical movement that operates a generator .
- the electricity created by the generator is transformed in order to be given a suitable form for distribution of the same .
- a transformation takes place in different steps such that the households shall receive a suitable voltage and current in order to operate, for instance , abovementioned electric motor.
- the present invention aims at obviating the above men- tioned disadvantage of previously known plants for production of hot water and at providing an improved plant .
- a primary obj ect of the invention is to provide a plant that makes use of a bigger share of the energy from the energy source that is used.
- Another object of the present invention is to provide a plant that converts natural energy to hot water, at a lower total cost than previously known plants . It is also an obj ect to ensure the supply of hot water to households/industries even when the individual household has a power failure .
- At least the primary object is achieved by means of the initially defined plant , which is characterized by the features that are set out in the characterizing clause of claim 1.
- Fig . 1 is a schematic illustration of an embodiment of a plant according to the present invention operated by a wind power plant ,
- Fig . 2 is a schematic illustration of an alternative embodiment of a plant according to the present invention operated by a water power plant
- Fig . 3 is a schematic illustration of another alternative embodiment of a plant according to the present invention operated by a wave power plant
- the thing that separates these plants 1 according to the present invention from conventional plants is that the hot water is created directly at the energy source, whereupon hot water of preferably 65-70 0 C is distributed to the end consumer, in contrast to previous solutions in which the kinetic energy of , for instance, water is converted into mechanical kinetic energy that is converted to elec- tricity that is distributed and which in its turn once again is converted to kinetic energy in order to operated a heat pump in order to heat the water of each end consumer.
- the unnecessary energy intensive intermediate stages between the energy source and the heat pump are removed.
- hot water may be created and distributed to the recipient/user to a cost that solely amounts to approximately 1/6 of the cost that is present in the energy supply/ heating solutions of today.
- the inventive plant 1 comprises, according to traditional heat pump manner, a refrigerant circuit 2 in which a refrigerant is circulated .
- a compressor 3 in order to compress the refrigerant whereupon the temperature of the same is increased substantially
- a condenser 4 in order to emit the heat stored in the refrigerant to a water supply network 5 connectable to the plant 1, for instance, a district heating system that supply a great number of recipients with hot water for tap water and local heating
- a expansion valve 6 in order to once again trans- port the refrigerant to the low pressure side or heat absorption side of the circuit 2 after the heat emission.
- the heat absorption/evaporation of the refrigerant takes place , either by the refrigerant circuit 2 itself , at least partly, is arranged at a suitable location in the geosphere , for instance, in a rock in such a way that the same has the function of an evaporator (see fig. 1) or that the refrigerant circuit 2 passes a separate evaporator 7 (see fig. 2) , to which also a collector 8 is connected.
- the collector 8 is in its turn arranged at a suitable location in the geosphere .
- the plant 1 comprises means for operating the compressor 3.
- the operating means of the compressor is constituted by a mechanism 9 that is exposed to natural energy.
- natural energy is here intended so called flowing energy in the shape of, for instance , water energy, wind energy and solar energy.
- the mechanism 9 is preferably constituted by a turbine , located, for instance, in a water power plant (according to fig. 2 ) , a wind power plant (according to fig. 1) or, for instance , a buoy in a wave power plant (according to fig. 3 ) , etc .
- the mechanism/turbine 9 is given a movement when the wind/water/ wave flows passed the same .
- a fiord mouth may be descry- bed in which the water always is in motion, as a consequence of, for instance , tidal phenomenon.
- a wave power plant according to the present invention which by means of the flowing water produces hot water that easily may be distributed to the settlement/town that eventually is located by the shore of the fiord.
- the water is used in this case , which is either directed to an evaporator 7 or in which the refrigerant circuit 2 may be arranged directly.
- the wave power plant according to fig. 3 consists of a buoy 9 that causes a movement of a mechanism arranged at the sea bed when the waves move the buoy up and down .
- a primary advantage of the inventive plant 1 is that, as a consequence of that the compressor 3 is mechanically operated directly by the mechanism 9 , a considerably bigger share of the energy that is received from the water/wind may be used to operate the compressor 3 than which was the case of previously known household heat pumps .
- the plant 1 according to the invention admits that the households/industrial plants may receive hot water to a lower cost per energy unit .
- this system is less susceptible to weather disturban- ces , since the hot water is always produced as long that there is water movement and wind, and consequently the heat in the individual household may easily by maintained despite a breakdown of the electricity supply.
- the household furthermore have solar cells for the household electricity as well as bottled gas for cooking and refrigerators , both the light and the cooking is ensured at a power failure .
- traditional electricity supply networks are not necessary at all at the establishment of a new infrastructure to areas without previously operating/existing infrastructure .
- Another advantage of the inventive plant 1 is that one furthermore may allow the mechanism/turbine 9 to operate a generator in order to produce electricity in a conventional way, in the areas where an operating and established electricity supply network already exists .
- the mechanical transmission is merely shown schematically in the drawings , and it should be pointed out that the same may present any suitable shape that is capable of performing the task of mechanically transmitting a power .
- the relationship that the mechanism is connected directly to a compressor via a mechanical transmission, shall be interpreted in its widest meaning, and thus conside- red to comprise any shape of mechanics , without intermediate electricity generating and/or electricity distributing steps , that is capable of performing the task of transmition power from the mechanism to the compressor.
- plants accor- ding to the present invention may j ointly provide hot water to a national water supply network. With the consequence that , if the production of hot water is interrupted in one plant , the supply of hot water to all connected recipients is ensured anyway.
