  • an energy recuperation system is generally shown at 10, and will hereinafter be referred to as the ERS 10.
  • the ERS 10 is used in conjunction with a process having a cooling demand/heat availability A and a heating demand/cool availability B.

  • the storage material is chosen so as to change phase (e.g., solid to liquid, liquid to gas or vice- versa) under generally atmospheric pressure within the recuperation storage system 11, following a heat- exchange sequence with a thermo-fluid that is part of the heat recuperation circuit 13 and/or cold recuperation circuit 14. It is preferred that the storage material undergo a phase change (e.g., liquid- solid and vice versa) as a function of the temperature variation required for the first refrigerant, so as to maximize the heat-retaining capacity of the energy recuperation by using the latent heat capacity of the recuperation refrigerant.
  • phase change e.g., liquid- solid and vice versa
  • the storage material is a compound of different materials which may include alkanes, N-paraffin hydrocarbon chain, glycerin, water, tridecane, tetradecanes, pentadecane, hexadecane, heptadecane, hydrocarbon wax, glycerol, 1,2,3- Propanetriol, glyceritol, glycerol, estol, 1,2,3- trihydroxypropane, glycyl alcohol, triglycerides, fatty acids, esthers, iso-propyl palmitate, silicone gel, salt hydrates, appropriately chosen as a function of the cooling demand A and the heating demand B.
  • the recuperation storage system 11 communicates with the cooling demand A by way of the heat recuperation circuit 13 to absorb heat, and with the heating demand B by way of the cold recuperation circuit 14, to supply heat as a function of the demand.
  • the heat and the cold recuperation circuits 13 and 14 are connected to a regeneration system which is used to charge the storage material at very low energy cost or with rejected energy, such as a dry cooler system with fans in heat exchange with the outside air (Direct free cooling module) , the heat rejection of cooling tower of chilled water system or an economizer integrated to a chimney or on the exhaust air of a specific process. Examples are provided hereinafter.
  • the heat recuperation circuit 13 and the cold recuperation circuit 14 typically are piping circuits extending between respective parts of the process and the recuperation storage system 11. Both circuits 13 and 14 are in a heat-exchange relation with the process and with the energy accumulator 11, but preferably not in fluid communication therewith. To be in heat- exchange relation, the circuits 13 and 14 are provided with heat exchangers, which are chosen as a function of the process and/or recuperation refrigerant.
  • Thermo-fluids circulate in the circuits 13 and 14, such as water, ethylene-glycol, propylene glycol, thermal oil, etc. Pumps or similar conveying means (compressed air network, etc.) are provided to induce the circulation of the thermo-fluids in the circuits 13 and 14. It is contemplated to have the circuits 13 and 14 in fluid communication with one another in a global circuit with suitable valves and controls. Similarly, the circuits 13 and 14 may be a same single circuit if a single part of the process needs cooling and heating (e.g., a tank in which the product is heated and then cooled) .

  • the controller system 12 has a controller 20.
  • the controller 20 is connected to the recuperation storage system 11, so as to obtain temperature data, or like parameters, associated with the storage medium.
  • the controller 20 is also connected to the cooling demand A and to the heating demand B of the process, for instance by way of various sensors (e.g., pressure sensors, temperature sensors [dry bulb and wet bulb temperatures] and probes, and the like), so as to obtain information pertaining to the energy demand. More specifically, the process is often precisely controlled to ensure, for instance, that the product is produced according to given standards. Accordingly, the process is typically equipped with sensors and the like obtaining accurate parameter data (e.g., temperatures, pressures, etc.). It is therefore contemplated to connect the sensors of the process to the controller 20 such that the controller 20 obtains the parameter data illustrating the cooling demand A and the heating demand B.
  • various sensors e.g., pressure sensors, temperature sensors [dry bulb and wet bulb temperatures] and probes, and the like
  • the controller 20 is connected to the various powered devices (e.g., pumps, solenoids valves, etc.) of the heat recuperation circuit 13 and of the cold recuperation circuit 14, which induce the flow of thermo- fluid between the demands A and B and the recuperation storage system 11.
  • the controller 20 therefore commands actuation of the circuits 13 and 14, as a function of the decisions taken by the controller system 12, to recuperate and store energy in the recuperation storage system 11.
  • An energy level calculator 21 is associated with the controller 20.
  • the energy level calculator 21 receives the temperature data pertaining to the cooling demand A and to the heating demand B of the process, and to the storage medium in the recuperation storage system 11. With the temperature data, the energy level calculator 21 calculates the real-time storage capacity in the recuperation storage system 11.

  • An operation identifier 22 is associated with the controller 20.
  • the operation identifier 22 receives the storage capacity value of the recuperation storage
  • the operation identifier 22 will therefore determine if and when one of heat recuperation circuit 13 and the cold recuperation circuit 14 is to be actuated to store energy in the recuperation storage system 11, in order to optimize energy consumption in view of the demands/requirements of the process.
  • a process controller C is provided to control the operation of the process. More specifically, a process is a sequence of steps that are often automated, whereby a process controller C typically controls the process, for instance by actuating the powered devices, by measuring the parameters associated with the process, etc.
  • the process controller C may indicate, in the form of process info, that a given step of the process has been reached and that there is a cooling demand/availability A or a heating demand/availability B at this step of the process.
  • the operation identifier 22 determines whether and when to send actuation, commands to the controller 20 such that either the heat recuperation circuit 13 or the cold recuperation circuit 14 is actuated to initiate energy recuperation.
  • a database 23 is provided to store process data. Such information may be considered by the operation identifier 22 to determine from the process parameters (e.g., temperature, pressure) when to initiate recuperation of energy through actuation
  • the process data stored in the database 23 may be updated.
  • the operation identifier 22 determines that, as a function of the storage capacity of the recuperation storage system 11 and of an indication from the process controller C that the process has a cooling demand A, the ERS 10 is capable of absorbing energy. Actuation commands are sent to the controller 20 by the operation identifier 22, such that the thermo-fluid is circulated between the recuperation storage system 11 and the cooling demand A. Heat is absorbed by the thermo-fluid and then released to the refrigerant in the recuperation storage system 11. Throughout this heat exchange, the energy level calculator 21 calculates the storage capacity of the recuperation storage, which information is updated with the operation identifier 22.
  • the operation identifier 22 Upon receiving process information from the process controller C indicating that the step requiring the cooling demand A is finished, or determining from the storage capacity that the heat exchange must end, the operation identifier 22 commands the controller 20 to stop the actuation of the heat recuperation circuit 13. The operation identifier 22 will subsequently determine how the energy stored in the recuperation storage system 11 can be used. For instance, if the energy level in the storage system 11 is high, the operation identifier 22 may wait for a demand indication of the process controller C to have the cold recuperation circuit 14 actuated to meet the heating demand B .
  • the use of ERS 10 allows energy to be stored for later use.
  • the demands A and B do not have to be synchronized for the heat exchange to occur, as the storage removes the factor of time from the heat exchange .
  • the cooling demand/heat availability A is a chimney releasing the by-products of combustion to the atmosphere. Accordingly, when combustion occurs, the by-products are a continuous source of heat that would otherwise be lost.
  • the operation identifier 22 receiving information from the energy level calculator 21 as well as temperature data from the chimney or indications from the process controller C, commands actuation of the heat recuperation circuit 13 to store energy in the recuperation storage system 11.

  • the cooling availability B is the outside air. Accordingly, when proper conditions apply (appropriate wet bulb temperature and/or dry bulb temperature) , the cold recuperation circuit 14 benefits from a continuous source of quasi-free cold or mild temperature heat to be stored and that would otherwise be unusable.

Therefore, the operation identifier 22, receiving information from the energy level calculator 21 as well as temperature data from the outside conditions sensors or indications from the process controller C, commands actuation of the cold recuperation circuit 14 to store energy in the recuperation storage system 11.
  • This heat transfer apparatus is used to separate the two cold circuits (14 and 31) in order to allow the cold transfer circuit to distribute energy to a sensible cooling process which cannot be mixed with the cold recuperation circuit fluid (for separate temperature control, for contamination risks reduction or for other physical reasons) .
