Description

    TECHNICAL FIELD
  • The present invention relates to a multi-service pedestal, in particular for ports and marinas, that is able to provide a variety of utilities such as electricity, tap water, television and telephone services to moored vessels, cabin cruisers and ships, generally called cruisers in the following. However, the pedestal according to the invention can be used also in camping areas for recreational vehicles and temporary shelters.
  • BACKGROUND ART
  • Small cruisers have commonly no air conditioning system within their cabin because of encumbrance and cost of maintenance thereof. The problem of air conditioning is particularly serious when the cruiser is in an area sheltered from the wind, e.g. a port or marina, especially when the weather is hot. Sometimes, as in lake areas, it is not possible to keep open portholes, hatches and windows during summer for ventilation, which allows mosquitoes and other annoying insects to come in.
  • Stoves and portable air conditioners are often used for the air conditioning within small cruisers. However, they consume a lot of electrical power and, furthermore, can cause fire as a result of their possible overheating.
  • U.S. Pat. No. 5,848,536 discloses a marine air conditioner, which could also be used as a heat pump. There is stated that “while the marine air conditioner according to the invention is particularly effective for boats in the twenty five foot range, the basic design according to the invention is highly advantageous for almost any size boat . . . the air conditioner according to the invention has a very low volume to cooling capacity ratio, and high efficiency”. The conditioner is associated with a cooling water pump whose inlet conduit passes through the hull of the boat for sucking the cooling water for the heat exchange with the condenser of the air conditioner.
  • Even if the air conditioner described in U.S. Pat. No. 5,848,536 is particularly developed for the purpose, however, the encumbrance and maintenance drawbacks above mentioned as well as cost and noise of the cooling water suction pump remain the same. Furthermore, the installation of the air conditioner involves, as mentioned above, the drilling of the hull below the waterline that cause various problems, including psychological ones, related to this need.
  • A marine system of this kind, which is called hydronic as it uses the circulation of water for the transfer of thermal power, is produced by Thermowell, Lecce, Italy. A central conditioning apparatus, such as a heat pump or a refrigerator, is placed in a room of a vessel, and its heat exchanger is cooled with sea water by a suction pump. The central conditioning apparatus is connected through a delivery pipe and a return pipe to a fan coil remotely situated on the same vessel for air conditioning.
  • U.S. Pat. No. 4,967,569 discloses a portable air-conditioning unit to be placed on a boat deck. The portable air-conditioning unit is enclosed in a shell divided into two compartments internally. A first compartment, containing a cooling coil and a fan, communicates only with a boat cabin to be conditioned through a hatch; the first compartment sucks internal air by a suction duct, cools said air and feeds back it into the boat cabin by a delivery duct. The second compartment is in contact with external air that cools a condenser of the air-conditioning unit.
  • It is understood that this air-conditioning unit needs to be transported onto the deck of the boat to be refrigerated and positioned so as to be adapted to its hatch. Besides the drawback arising from the transport of the air-conditioning unit and the adjustment of its position in situations that are different from boat to boat, there is the problem of a poor performance due to the fact that the heat exchange takes place in the air conditioner only with the air.
  • SUMMARY OF THE INVENTION
  • The present invention aims to overcome the above mentioned drawbacks associated with the installation of a fixed air-conditioning system on board of a vessel, but also with the transport of an air conditioner and the adjustment thereof to the hatch or other opening of a cabin to be conditioned.
  • A main purpose of the present invention is to provide an air conditioning within a moored cruiser without the need to install a central conditioning apparatus on board, i.e. the main part of a conditioning system for heating and cooling the air.
  • To achieve the above mentioned purpose, the present invention, as defined in claim 1 attached to this description, provides a multi-service pedestal, in particular for a quay of a port or marina, pedestal that has a support structure and is adapted to provide various utilities, such as electricity, tap water, telephone and television connections, to a cruiser moored at the quay, further comprising a central conditioning apparatus which is situated in the multi-service pedestal and is able to be connected to a terminal unit located on board the moored cruiser for conditioning indoor air.
  • Advantageously, the invention provides users with a simple, safe and cheap air conditioning and heating system. A user shall only have to accommodate on board a small fan powered terminal unit connected to the central conditioning apparatus for cooling or heating that is on a quay or pier, through a hose that functions as a sheath containing two pipes, namely a delivery pipe and a return pipe, which connect the central conditioning apparatus to the terminal unit; the pipes allow the circulation of chilled or heated liquid. An electric cable for the thermostatic control of the system is also contained in the aforesaid hose.
  • Various embodiments of the multi-service pedestal according to the present invention are defined in the claims dependent on claim 1.
  • According to a first embodiment of the invention, the pedestal has a hollow load bearing structure that is mounted on the quay or pier and is electrically powered with a cable that enters the support structure and is connected to industrial sockets with interlock, in addition to an electrical socket for supplying the central conditioning apparatus.
  • Passing through the hollow structure, which can be made of steel, is a tube from the water mains for water outlets controlled by taps.
  • The central conditioning apparatus is connected by hoses and quick couplings to two tubes that run within the load bearing structure, exit the base thereof and continue through the quay or pier or along them until they reach the water surface. One of the two tubes is a suction tube, which, suitably protected by a filter, sucks water. The other one, after having served a heat exchanger, discharges the water. A pump located in the pedestal is provided in the suction tube.
  • Housed in the upper part of the pedestal, is a LCD or LED screen, duly inclined to allow a best vision. The LCD or LED screen, via a cable connection or wi-fi, allows the user to take advantage of interactive promotions for dedicated user services that a manager decides to offer, as well as an advertising schedule.
  • In a second embodiment of the invention, the support structure of the pedestal has profile, preferably of stainless steel, in a form of an omega rotated upwards, having a lower part connected by a support plate to the ground, an upper part in which a computer screen is placed frontally, and a central recess intended to removably receive said central conditioning apparatus.
  • The omega-shaped profile of the support structure according to the second embodiment of the invention is somewhat narrow and is coated with slats protruding from both sides of the support structure. The slats are made of wood or composite material similar to those of the decking of the pier or quay to which it is attached.
  • The central conditioning apparatus is encased in a housing made of material resistant to corrosion and is coated with the same slats of composite material or wood that cover the support structure that hosts it. So doing, an aesthetic continuity is obtained when both the central conditioning apparatus is inserted in the central recess of the support structure, and it is not.
  • Even in the second embodiment the central conditioning apparatus is connected to the fan powered terminal unit, which is enclosed in a durable, small, possibly isolated acoustically container. It includes a finned heat exchanger, a centrifugal fan and inlet grille.
  • In a third embodiment of the invention, the support structure has a squared S-shaped profile, extending upward in a rearward inclined portion to receive a computer screen, the squared S-shaped profile comprising a C-shaped recess intended to removably receive said central conditioning apparatus and a lower part in the form of an inverted L that is adapted to receive a permanent housing for utilities.
  • In a fourth embodiment of the invention, the support structure has a squared S-shaped profile, extending upward in a rearward inclined portion to receive the screen of a computer, the squared S-shaped profile comprising a C-shaped recess intended to removably receive said central conditioning apparatus and a lower part in the form of an inverted L. The C-shaped recess is pivoted by means of cylindrical hinges on the lower part in the form of an inverted L that is intended to removably receive a housing for utilities. Such housing is likely to be removed from the multi-service pedestal by turning upwards the C-shaped recess, after said central conditioning apparatus has been removed from it.
  • Advantages of the invention are evident for both the manager of the pedestals on the quay and the users. A main advantage lies in its function of offering a comfortable temperature within a cruiser; other advantages include reduced size of the fan powered terminal unit, low noise due to the only presence of a fan in the room to be conditioned, easy maintenance, prevention of vandalism, theft or tampering, especially in the embodiments in which the housing of both the central conditioning apparatus and the utilities is removable from the support structure of the pedestal. Other advantages derive from the modularity of the multi-service pedestal according to the invention, which allows the manager to purchase the pedestal from the manufacturer thereof as desired, and to maintain it easily thanks to the removable housing of central conditioning apparatus and utilities. A decisive factor is the reliability in use: there is no need of heaters, portable air conditioners, or stationary air conditioning systems on board, with a result of greatly reducing the risk of fire due to overheating of electrical equipment, and of cruiser sinking due to a malfunction of the sea cocks. In general the advantage of the pedestal according to the invention is to provide a service to those who can not or do not want to bear the cost of purchasing a stationary air conditioning system on board or just do not have the sufficient space on their cruiser. Finally, the pedestal allows a reduced power consume with respect to heaters and portable air conditioners.

  • DESCRIPTION OF INVENTION EMBODIMENTS
  • First, reference is made to FIGS. 1 to 3, which show the only multi-service pedestal in a front perspective view, and the multi-service pedestal connected to a fan coil unit in front and rear perspective view respectively, according to a first embodiment of the present invention. The multi-service pedestal generally indicated as 1 has a hollow load bearing structure 10 extending upwards. The hollow load bearing structure 10 has a front side 11 from which a computer screen 5 protrudes upward. The hollow load bearing structure 10 is closed by panels both in front and rear. By removing the lower panels of the front side 11, as shown in FIG. 2, a central conditioning apparatus generally indicated as 6 becomes accessible. FIG. 3 shows the rear side 12 of the hollow load bearing structure where a door 13 openable to obtain access inside is provided. Associated to the central conditioning apparatus 6 is a suction pump 7. Indicated as 8 and 9 are a suction tube of cooling water, which could be taken from the same water basin where a cruiser is moored, and a discharge tube respectively for discharging the cooling water to the basin after a heat exchange in an open loop heat exchanger as described later.
  • Provided on one or both side walls of the hollow load bearing structure 10 are an electric power socket 14 with a device of mechanical interlock and a faucet 15 for tap water.
  • As shown in FIG. 3, a delivery pipe 16 for delivering a conditioning liquid to a terminal unit 18 and a return pipe 17 thereof protrude from the rear side 12 of the hollow load bearing structure, in which there is a closed loop heat exchanger of a working fluid of the central conditioning apparatus, described in detail below. The terminal unit 18 is a conventional fan coil having a conditioning liquid coil (not shown in the figure) that is connected with the delivery and return pipes 16, 17 of the closed loop heat exchanger.
  • The delivery and return pipes 16, 17 are lined with an insulating material adapted to reduce the heat exchange with the outside, and joined together with a sheath in a single hose 19.
  • Reference is made now to FIGS. 4, 5 and 6 which are a front view, a rear view, and a side view respectively, of a second embodiment of a multi-service pedestal 20 according to the present invention. In these figures the same reference numerals are used for parts identical or similar to those in the first embodiment, which is described in FIGS. 1 to 3.
  • The multi-service pedestal 20 has a support structure 21 with a shaped profile in the form of omega rotated upward, having a lower part 22, a central part 23, and an upper part 24. The lower part 22 is connected to a support plate 25 that is shown as mounted on a pier P in FIG. 6. The support structure 21 is provided in front with a panel coating 26. The frontal width of the support structure 21 is less than that of the panel coating 26, as shown in FIG. 5.
  • The upper part 24 of the support structure 21 has frontally a computer screen 5. Thanks to the particular profile of the support structure 21, the central part 23 has a recess 27 intended to removably receive a central conditioning apparatus located within a housing 28, which is also frontally coated with a panel coating 29.
  • The support structure 21, which can be made with a stainless steel section with a rectangular cross-section, is internally hollow to allow the passage of utilities. In particular, electrical cables 30 for power supply to a socket 14 with mechanical interlock, and a tap water tube 31 to a faucet 15 are shown. The tap water tube 31 is connected to the water mains. The electrical cables 30 also supply the central conditioning apparatus, as shown by the tract 35 between the support structure 21 and the housing 28 of the central conditioning apparatus, and further the computer screen and other utilities not described in detail. Passing inside the support structure 21 are a suction tube 8 of cooling water, which is sucked from a water basin A, and a discharge tube 9 for discharging the cooling water to the basin after the heat exchange in an open loop heat exchanger contained within the housing 28, which will be described later. Indicated with the same reference numerals 8 and 9 are tracts of the suction tube of cooling water and of the discharge tube respectively, in the passage between the support structure 21 and the housing 28 of the central conditioning apparatus. In particular, partially shown in FIGS. 5 and 6 are also delivery and return pipes 16, 17 of the closed loop heat exchanger of the central conditioning apparatus. The delivery and return pipes 16, 17 are lined with an insulating material, and joined together with a sheath in a single hose 19. Provided inside the sheath is also a low voltage power cable 33 for a thermostat mounted, as it will be shown below, inside the cruiser where the fan coil unit is placed.
  • As shown in FIG. 7, which is a side view in an enlarged scale of the multi-service pedestal in FIG. 4, the central conditioning apparatus is removable from the support structure 21 because its housing 28 can be extracted and re-introduced into the recess 27 of the support structure 21, after detachment of the connecting pipes and tubes and the power cable, as it will be explained in the following with reference to other embodiments. The arrow F indicates the direction of re-introduction.
  • Reference is made now to FIG. 8, which is a schematic side view of the second embodiment of a multi-service pedestal 20 according to the present invention installed on a pier P and rear connected to a terminal unit 18 mounted onboard a cruiser C moored at the same pier P. The central conditioning apparatus placed inside its housing 28, which is inserted in the multi-service pedestal 21, sucks the cooling water from the basin A through a filter 32 and the suction tube 8 and discharges the cooling water exiting the open loop heat exchanger in the basin through the discharge tube 9.
  • Furthermore, the central conditioning apparatus is connected as described above, through the single hose 19 to the terminal unit 18, i.e. a fan coil, onboard the moored cruiser C. The hose 19 is inserted into the cruiser C through a window 34 of the same. It should be clear that a quick connect fitting to allow connection of the hose 19 can be provided in the cruiser C in order to prevent the opening of the porthole, hatch, windows and skylights and the consequent dispersion of heating or cooling. Alternatively, a passage hole of the hose 19 may be closed with a safety cap, removable only for the operation of air conditioning.
  • A user U is shown operating the computer screen 5. The computer screen 5, which may be a touch screen, can be used to receive weather and sea communications, and any other service information or advertising.
  • The computer screen positioned on the inclined surface to allow the best vision, via a cable connection or wi-fi, allows the user to take advantage of an interactive service for the promotion of dedicated services, as well as an advertising schedule.
  • The multi-service pedestal 21, although not shown, may also have telephone and television cables, and any other desired utility.
  • The power cable 30 from the floor of the pier P having variable voltage 220/380 V supplies sockets 14, 14 placed at a sufficient distance from the floor and attached to the support structure 21. The sockets with interlock have a protection guaranteed by a differential circuit breaker.
  • The tap water comes from the water mains through the tube 31 and branches into the two quick coupling faucets 15, 15, placed to the sides of the support structure 21.
  • Housed inside the support structure 21 is the suction tube 8 that sucks the water from the basin A below the pier P or quay for the cooling of the heat exchanger of the central conditioning apparatus. The filter 32 protects the tube from obstruction. The discharge tube 9 ensures the discharge of the same water after cooling. Both tubes are connected with a quick connection on the support structure in the vicinity of the housing 28 of the central conditioning apparatus. Applied to the support structure 21 of stainless steel is the panel coating 26 of slats that are made of composite material or wood and fastened by means of screws. On top of the support structure 21 the computer screen 5 is resistant to water, UV rays, and accidental bumps. The base of the frame structure 21 can be rotated by 45° clockwise and counterclockwise, thereby facilitating the wiring of power and water utilities.
  • The central conditioning apparatus is within the housing 28, which is resistant to water and dust, and covered in the front by the panel coating 29 of slats made of composite material or wood identical to the panel coating 26 that covers the front part of the multi-service pedestal 20.
  • In order to illustrate in more detail the above described, reference is made to FIG. 9, which is a diagram of the conditioning system of the multi-service pedestal according to the present invention. Also in FIG. 9 the same reference numerals of the previous figures are used. Located in the housing 28 that is placed on the multi-service pedestal 20, is the central conditioning apparatus that will be described in greater detail in FIG. 10, which is a schematic representation of its components. The cooling water is sucked through the filter 32 from the basin A by the suction tube 8 by means of a motor pump 7 powered with a power supply 36 from the multi-service pedestal 20. The cooling water enters the housing 28 through the suction tube 8 and, after passing through the open loop heat exchanger, returns to the basin A with the discharge tube 9.
  • The central conditioning unit in the housing 28 is connected to the fan coil terminal unit 18 through the hose 19 (shown in FIG. 8) which contains inside the delivery and return pipes 16, 17 of the closed loop heat exchanger of the central conditioning apparatus and the low voltage power cable 33 for a thermostat 37 mounted inside the cruiser C. The fan coil terminal unit 18 is powered via a cable and a plug 38 from the power supply of the cruiser C.
  • With reference to FIG. 10, the main components of the central conditioning apparatus of the traditional type that is generally marked as 6 are described.
  • The central conditioning apparatus 6 comprises a compressor 39 of a working fluid, a four-way valve 40, a four-way coil 41, a suction separator 42 with receiver for the working fluid in liquid phase, a filter 43 and a thermostatic valve 44, as well as a low pressure switch 45 and a high pressure switch 46.
  • Present in the central conditioning apparatus 6 are an open loop heat exchanger 47 for the exchange of heat between the working fluid and the cooling water sucked by the cooling water suction pump 7 (FIG. 9), and a closed loop heat exchanger 48 of the working fluid of the central conditioning apparatus 6. In both the heat exchangers the working fluid flows in tubing coaxial to a cooling water serpentine and to a conditioning liquid serpentine that exchanges heat with the fan coil terminal unit respectively.
  • In particular, in the open loop heat exchanger 47 the pipe of the working fluid, indicated in the drawing with a line, is shown as entering the coaxial coupling 49, where the sucked cooling water comes, and as exiting in the coaxial coupling 50 from which the cooling water flows returning to the basin A. Accordingly, the pipe of the working fluid is inner in the open loop heat exchanger 47, i.e. is jacketed in the larger diameter tube of the cooling water.
  • In the closed loop heat exchanger 48 the inner pipe of the working fluid, which is also indicated in the drawing with a line, is shown as entering the inlet coaxial coupling 51, in which the conditioning liquid from the fan coil terminal unit 18 arrives in the return pipe 17 (FIG. 9). Shown as 52 is a reservoir of the conditioning liquid that may be water mixed with antifreeze, and as 53 a pump for its movement. Indicated as 54 is the coaxial coupling of the outlet working fluid pipe to the delivery pipe 17 toward the fan coil terminal unit 18.
  • The closed loop heat exchanger 48 has opposite ends, and the open loop heat exchanger has an inlet end where probes for the detection of the temperature are located. More in detail, indicated as S1 in FIG. 10 is a probe for the detection of the working fluid temperature at the entrance of the coaxial coupling 51 of the conditioning liquid returning from the fan coil terminal unit 18 to the closed loop heat exchanger 48; indicated as S2 is a probe for the detection of the working fluid temperature at the exit of the coaxial coupling 54 of the conditioning liquid delivered to the fan coil terminal unit 18 from the closed loop heat exchanger 48; and indicated as S3 is a probe for the detection of the working fluid temperature at the entrance of the coaxial coupling 49 with the cooling water coming through the tube 8 from the suction pump 7 in the open loop heat exchanger 47.
  • Although not shown in FIGS. 6 and 8, into the central conditioning apparatus 6 the connections with the input and output tubes 8, 9 and with the cooling water supply and return pipes 16, 17 of the conditioning water are made via quick couplings (not shown in detail) inserted into the support structure 21 of the multi-service pedestal 20.
  • The hose 19 which joins the delivery and return pipes 16, 17 to the fan coil terminal unit 18 is boarded and housed below deck through the window 34, or a porthole, a skylight or a manhole. The fan coil terminal unit 18 is placed in the room to be cooled or heated. The fan coil terminal unit 18 can be of the traditional type, comprising a solid stainless metal casing possibly insulated with sound absorbing materials inside which are a finned heat exchange battery, a centrifugal fan, an inlet grille and a thermostat.

  • In fact, after removing the housing 28 of the central conditioning apparatus and rotating upward the C-shaped recess 78, the utility housing 81, no longer restrained by the cover element 82, can be removed.
  • As it is evident, the representation in FIGS. 15 to 17 is schematic, and any configuration of support structure that allows the installation and removal of the housing of the central conditioning apparatus and the utility housing can be provided.
  • This is particularly useful, not only when the relevant apparatuses have to be saved because not in use but also when they have to be inspected. Their mobility reduces the number of operations on site, with a result of reducing operating cost.
  • Evident are the advantages of the present invention that consists of a combination of a multi-service pedestal for ports and marinas and an air conditioning system. The invention allows to offer fresh and warm air inside cruisers that have no stationary air conditioning system on board due to the encumbrance or cost thereof.
  • The multi-service pedestal uses an air conditioning system comprising a central conditioning apparatus removably inserted in the multi-service pedestal, and a small, silent fan coil terminal unit onboard the cruiser when it is moored. The central apparatus and the terminal unit are connected through hoses that carry and circulate heated or chilled liquid. The temperature in the room to be conditioned is controlled by a thermostat inserted into the terminal unit, which also adjusts the speed of the air flow.
  • The multi-service pedestal with air conditioning system takes advantage of its natural place near seas, lakes and rivers in order to use the water in the conditioning process as in most air conditioners installed on board vessels.
  • The advantage lies in the fact that the water cooling pump and central conditioning apparatus remain on the quay or pier and only the small terminal unit is placed on board. Small boats can thus benefit from an air conditioning system that replaces dangerous heaters and bulk portable air conditioners.
  • The multi-service pedestal with air conditioning system allows marinas and ports to offer a rental service of air conditioning system, with the result of increasing the safety of people and cruisers, the usability of the cruiser throughout the year and, consequently economic benefits for operators of marinas and ports that would increase their volume of business.
  • The multi-service pedestal according to the present invention may be marketed with or without the air conditioning system, the central conditioning apparatus being a removable element and the pedestal being ready to host it via easy connection with pipes and cables.
  • As an alternative to cooling with water taken from the surrounding environment, the central conditioning apparatus located on the multi-service pedestal can be fitted with an air cooling, possibly with forced ventilation.
  • In its various embodiments, the multi-service pedestal has a simple design that allows rapid and economical maintenance of the various components that constitute it. The use of fully recyclable coating materials such as extruded wpc (wood plastic composite) made of wood dust and polyethylene, and the main steel structure, make the multi-service pedestal an environmental friendly product.
  • Without departing from the invention, the multi-service pedestal can still be made with any design and material. Electrical and electronic components for controlling utilities and for metering energy and water, and further motion detectors, cameras, webcams, phone service or internet can be added.
  • The central conditioning apparatus is enclosed in a housing made of a corrosion-resistant material that is coated with the same slats of composite material or wood covering the support structure that houses it. By doing so, an aesthetic continuity is obtained when the central conditioning apparatus is inserted into the pedestal.
  • It should be appreciated that the multi-service pedestal according to the present invention may be placed, besides in ports and marinas, even on campsites or other picnic areas, where so-called recreational vehicles such as caravans, campers, motor homes park, or temporary and permanent shelters such as tents and bungalows for the outdoors are planned. Without making substantial changes, except that providing the open loop heat exchanger more convenient for the surrounding environment, the central conditioning apparatus can be removably placed in a support structure of a multi-service pedestal according to the invention and be connected to a terminal unit placed on the recreational vehicle or in the temporary or permanent shelter for conditioning the air within them by heat exchange with a conditioning liquid.
