Definitions

  • the present invention relates to a heat exchanger apparatus and more particularly, but not exclusively, to an apparatus of the type used as part of an industrial or domestic central heating arrangement.
  • the components of the system i.e. the heat source, pumps, heat exchangers and the like, are fluidly connected together by means of pipes or conduits.
  • the pipes are generally arranged to communicate hot or cold water between the components of the system such as from a heat source, via pumps, to one or a series of radiators.
  • these components are connected by a series of pipes which have been pre-formed, or bent, into the required geometry.
  • the pipes are generally formed using specialist equipment so as to fluidly connect the various components together and to provide the required flow path(s) between components.
  • Typical CHP systems generally comprise a motor/generator set, a heat storage unit, a boiler and a heat pump which are required to consume as small a space as possible.
  • the heat (and electrical) source, together with the heat exchangers, pumps, valves and associated interconnections are often all contained within a single casing and it is desirable to minimise the size of the casing and thereby the overall space which the unit consumes.
  • a manifold or distributor arrangement can be used as a common conduit to which a number of components can be connected, thereby allowing fluid to flow between inlet and outlet ports along the manifold and between respective components. This does not however provide for specific flow paths between components.
  • WO2007/066135 An example of a distributor for providing a space saving arrangement can be seen in WO2007/066135 .
  • This distributor allows for a space saving in the components used to create the required flow paths from various inputs and outputs in the installation.
  • this distributor is arranged to receive fluid after heat exchange has occurred and it does not provide any improvement in the arrangement of the heat exchanger and related parts, such as pumps and the associated pipework.
  • the heat exchanger apparatus will include a heat exchanger with primary and secondary circuits, a pump for each of the primary and secondary circuits, and associated valves for control of the flow. It is important in many situations to use a heat exchanger since it is necessary to separate systems with different pressures.
  • the coolant circuit may have a maximum pressure that is not much higher than 1 bar.
  • a heating system for a building can have a design pressure of 3 bar or even up to 6 bar in tall buildings. There is hence a need for an efficient installation design that can include a heat exchanger.
  • FIG. 2005/036060 An example of a heat exchanger system used in the context of CHP devices is found in WO 2005/036060 .
  • Figure 1 of that document which is identical to Figure 1 herein, shows a known heat exchanger arrangement, which is commonplace.
  • a heat exchanger 11 has a primary side and secondary side.
  • the primary side has an input 20 and an output 19.
  • the secondary side has an input 18 and an output 21.
  • Fluid such as water flows from a heat source 13, for example a boiler or engine, through the heat exchanger primary side and back to the heat source 13 again. This forms a primary circuit 23.
  • a heat load 14 for example a space heating system such as a radiator system, through the secondary side of the heat exchanger and back to the load 14.
  • Heat is thereby transferred to the secondary circuit 22 from the primary circuit 23. Movement of fluid through the heat exchanger circuits is controlled by a primary side pump 10 and secondary side pump 7.
  • the actual temperature of the water in the secondary circuit 22 is a function of the temperature differential between the two circuits, the thermal efficiency of the design of the heat exchanger 11, and the mass flow rate of the circuits and of the degradation of the heat exchanger.
  • U1 discloses a domestic water heater comprising a plate heat exchanger, oriented at an angle to the vertical to avoid cold water flowing to a hot water tap.
  • EP 2 413 046 A1 discloses a domestic water heater comprising a heat exchanger showing all features of the preamble of independent claim 1.
  • the invention provides a heat exchanger apparatus comprising: a heat exchanger, the heat exchanger having a primary side and a secondary side, the secondary side having connections for a secondary side inlet and a secondary side outlet, and the primary side having a connection for a primary side inlet, wherein a first end of the heat exchanger has the connection for the primary side and one connection for the secondary side, and wherein a second end of the heat exchanger has the other connection for the secondary side; a primary circuit pump for propelling fluid through a primary circuit from the primary side inlet to a primary side outlet; a secondary circuit pump for propelling fluid through the secondary side of the heat exchanger and a through a secondary circuit connected thereto from the secondary side inlet to the secondary side outlet; and a secondary side manifold arrangement for connecting the secondary pump to the heat exchanger and to the secondary circuit; wherein both the primary pump and the secondary pump are arranged in parallel with the line between the first end and the second end of the heat exchanger and each of the pumps have
  • the layout is as follows: the primary side outlet of the heat exchanger is at the top of the heat exchanger, which is in use vertically oriented, and this is connected by a first part of the primary side manifold arrangement to the primary circuit pump; the outlet of the primary circuit pump connects via the second part of the primary side manifold to the return for the primary circuit; the second part of the primary side manifold also connects the primary circuit flow to the heat exchanger primary side inlet; the secondary side inlet of the heat exchanger is at the top of the heat exchanger and this is connected by the first part of the secondary side manifold arrangement to the outlet of the secondary circuit pump; the second part of the secondary side manifold arrangement includes a feedback conduit connecting the secondary side outlet of the heat exchanger to the inlet of the secondary circuit pump; and the second part of the secondary side manifold arrangement also connects the secondary side outlet of the heat exchanger to the return for the secondary circuit, and connects the secondary circuit flow to the inlet of the secondary circuit pump; wherein a three-way valve controls the
  • the manifold arrangement for one circuit may be split into two parts, one part forming a coupling between the pump and the heat exchanger, and a second part forming couplings between the pump and the circuit and between the circuit and the heat exchanger.
  • this second part of the manifold comprises connectors for coupling to the circuit, with the connectors being aligned and facing in the same direction.
  • the connectors face away from the pump and are parallel with the line between the two ends of the heat exchanger. In the common situation where the line between the two ends of the heat exchanger is vertical then the connectors will be aligned with the vertical, and may for example be facing downwards.
  • the heat exchanger connections will exit the heat exchanger in a direction perpendicular to the direction between the two ends of the heat exchanger.
  • the manifold arrangement preferably acts to redirect the flow direction so that it is parallel with the direction between the two ends of the heat exchanger and aligned with the flow direction for the relevant on-going connection point at the pump or at the circuit.
  • the flow direction from an outlet of the primary side for the heat exchanger may be turned by the manifold so that it is aligned with the inlet of the primary side pump.
  • the manifold arrangement is a cast and/or machined manifold.
  • the manifold is preferably not formed by conventional plumbing. Instead it may be a custom part specifically designed to form the required connections between the heat exchanger, the pump and the circuit. This allows for the design of the parts to be set prior to final assembly, which makes installation and final assembly of the heat exchanger apparatus far simpler. Since final assembly often occurs on site, where connections are made with existing heat sources and heat loads, then this can be a big advantage in terms of reduced time and reduced complexity, and hence reduced costs for the end user.
  • the flow paths may have a circular geometry. This allows for the advantages of the circular shape of the flow paths to be maintained despite the fact that conventional plumbing is not used.
  • the heat exchanger may be an opposed (counter) flow heat exchanger, wherein the primary side and secondary side have flow directions that are in parallel but in opposite directions. That is to say, the first end of the heat exchanger will have an inlet for one side of the heat exchanger and an outlet for the other side, whereas the second end of the heat exchanger will have an outlet for the one side and an inlet for the other side.
  • the direction between the two ends of the heat exchanger is also the direction of fluid flow within the heat exchanger, with fluid flowing on one side from the first end to the second end and on the other side in from the second end to the first end.
  • one end of the heat exchanger will be a hot end, with maximum temperature on both sides, and the other end of the heat exchanger will be a cold end, with the minimum temperature on both sides.
  • the primary side is designated as the side connected to the heat source, and hence the heat exchanger in this arrangement may have a primary side inlet connected to the heat source at the hot end, a primary side outlet returning cooled flow to the primary circuit at the cold end, a secondary side inlet receiving flow from the secondary circuit at the cold and, and a secondary side outlet returning heated flow to the heat load on the secondary circuit at the cold end.
  • the heat exchanger may be a cross flow heat exchanger.
  • Some heat exchangers such as brazed plate heat exchangers, do not provide a perfect counter flow but instead have a cross flow, although they can have a similar effectiveness to counter flow heat exchangers.
  • the heat exchanger of the first aspect hence may be a brazed plate heat exchanger.
  • This type of heat exchanger also has first and second ends with connections grouped in pairs at each end.
  • the heat exchanger may be oriented, in use, so that the direction between the first and second end is generally vertical and the hot end is at the top of the heat exchanger.
  • This arrangement is often used in prior art systems since the flow through the heat exchanger is not disturbed by natural convection.
  • the heat exchanger apparatus is arranged, in use, so that the cold end is at the top of the heat exchanger. This allows for the pump to be at the cold part of the circuit that it drives. This is a particular advantage for higher temperature systems, as well as for high flow systems. It has been found that in such systems the effects of natural convection can be ignored.
  • the pump may be at the cold part of the circuit, and hence in some embodiments the heat exchanger apparatus may be arranged so that the pump is at the cold part of the circuit.
  • the pump when there are similar pump and manifold arrangements on both sides, then since the cold water from primary and secondary sides will generally be connected to the same end of the heat exchanger (for counter flow) then the pumps will also be connected to the same (cold) end. Then, when the pumps are mounted parallel to the heat exchanger, the other end of the pumps will get close to the other connections of the heat exchanger. Thus all four connections are now close together and can be oriented in the same direction. This provides an effective and compact arrangement.
  • the apparatus may include a feedback conduit connecting the inlet and outlet of the heat exchanger and a three-way valve for controlling the flow through and within the manifold arrangement.
  • the first aspect preferably references a pump and manifold on the secondary side, with the three-way valve being coupled to the manifold arrangement on the secondary side to control the flow through a feedback conduit on the secondary circuit.
  • the feedback conduit may be formed as a part of the manifold arrangement.
  • the feedback conduit may allow for the inlet and outlet of the pump to recycle all or a part of the secondary flow through the heat exchanger without the flow passing through the secondary circuit.
  • this three-way valve is particularly preferred for this three-way valve to be controlled based on indications of the temperature on the primary side of the heat exchanger, for example in accordance with the control arrangement described in WO 2005/036060 .
  • the feedback conduit on the secondary circuit can advantageously be used to control the temperature of the primary circuit.
  • the three-way valve may advantageously be mounted in line with the secondary circuit pump, i.e. with an inlet or an outlet of the valve connecting to the inlet or outlet of the pump as well as to the circuit and the feedback conduit. This location for the valve allows for the most compact arrangement for the heat exchanger apparatus.
  • the heat exchanger apparatus is used with a combined heat and power device, with the heat exchanger transferring heat from a primary circuit which is the cooling circuit of the combined heat and power device to a secondary circuit connected to a heat load.
  • the heat load may be a hot water storage system and/or a space heating system.
  • Figure 2 shows an embodiment incorporating the proposed new heat exchanger apparatus. It will be understood that there is a significant difference in the orientation and location of the pumps for the two circuits 22, 23 for the arrangement of Figure 2 compared to that of Figure 1 . There are also significant changes in the manifold arrangement that forms the connections for the primary and secondary circuits.
  • the primary circuit pump 10 and the secondary circuit pump 7 are in parallel with the heat exchanger 11.
  • the flow direction between the inlet and outlet for the pumps 7, 10 is in parallel with the flow direction between the inlets 18, 20 and outlets 19, 21 of the heat exchanger.
  • the flow direction is vertical in each case.
  • the system of Figure 2 communicates heat between a primary circuit 23 and a secondary circuit 22 through the heat exchanger 11. It consists of two pumps 7, 10, one heat exchanger 11, two lower manifold arrangements 6, 12 with internal and external connections 1, 2, 3, 4, joining the pumps 7, 10, heat exchanger 11 and return/flow for the two circuits 22, 23, and also two upper manifold arrangements, 8, 9 with internal connections between the pumps 7, 10 and the heat exchanger.
  • the heat exchanger 11 is of a type where the connections 18, 19, 20, 21 are grouped in pairs, and where each group of connections has one connection of the primary circuit and one of the secondary circuit.
  • the primary side outlet 19 and secondary side inlet 18 are at one end of the heat exchanger 11 and at the other end we find the primary side inlet 20 and secondary side outlet 21.
  • This type of configuration is common for plate heat exchangers, and thus the heat exchangers described herein may be plate heat exchangers.
  • the lower primary side manifold 12 is mounted to primary side inlet 20 of the heat exchanger 11 and provides a connector 2 to join to the primary circuit flow and a connector 1 to join to the primary circuit return.
  • the primary circuit return is joined to the outlet of the pump 10 and the inlet of the pump 10 is connected by the upper primary side manifold part 9 to the primary side outlet 19 from the heat exchanger 11.
  • the manifold 12 is elongate and mounted basically perpendicular to the heat exchanger 11. In the preferred arrangement the heat exchanger 11 is positioned vertically and the manifold 12 horizontally on the lower set of connections from the heat exchanger.
  • a similar arrangement is used for the secondary side lower manifold 6, which has a connector 3 to join to the secondary circuit return and a connector 4 to join to the secondary circuit flow.
  • the secondary circuit flow is joined via the connector 4 to the inlet of the secondary circuit pump 7 and the secondary circuit return is joined via the connector 3 to the secondary side outlet 21 of the heat exchanger 11.
  • the upper secondary side manifold part 8 couples the secondary circuit pump 7 to the inlet 18 for the secondary side of the heat exchanger 11.
  • the lower manifolds 6, 12 together hold all of the external connections 1-4 to the heat source 13 (primary circuit 23) and heat load 14 (secondary circuit 22).
  • One pump 10 is mounted on the manifold to the left of the heat exchanger 11; the other pump 7 is mounted to the right. Both pumps 7, 10 are mounted in parallel with the heat exchanger 11. This results in a compact arrangement for the heat exchanger apparatus. With a vertical arrangement for the heat exchanger 11, one pump will pump upwards, the other downwards. This provides the counter flow in the heat exchanger 11.
  • connection 1, 2, 3, 4 on the manifolds 6, 12 are close together and aligned facing in the same direction. They are hence easily accessible for coupling the heat exchanger apparatus to the heat source and heat load circuits.
  • the installer can provide suitable pipework in advance for the required connections, and final assembly/installation of the heat exchanger apparatus is made simple since it is just necessary to join the connectors 1, 2, 3, 4 to the respective circuits, and possibly also to join the manifolds to the pumps and heat exchanger. Later maintenance is also made more straightforward, since the manifold arrangement allows for easy disconnection and removal of the heat exchanger apparatus, to permit replacement of one of the pumps 7, 10 or the heat exchanger 11.
  • the invention is not limited to this and in fact the primary loop and the secondary loop could be switched.
  • the heat exchanger 11 might be hot at the top and cold at the bottom.
  • the heat exchanger 11 is normally used such that the hot water from the heat source 13 enters at the top of the heat exchanger 11 and leaves as cooled water at a lower connection of the heat exchanger 11. Then the cold return water of the heat load 14 enters at a lower connection and after being heated it leaves at the top of the heat exchanger 11.
  • this is important since the flow through the heat exchanger 11 is then not disturbed by natural convection.
  • a feedback conduit is provided in the lower secondary side manifold part 6 and a three-way valve 5 is used on the secondary circuit 22 to control feedback of fluid from the secondary circuit pump outlet through the secondary side inlet 18 of the secondary side of the heat exchanger 11. This can be used to control the temperature on the primary circuit 23.
  • Figures 3 to 6 illustrate four different possible ways to build the three-way valve 5 into the manifold 6.
  • the three-way valve 5 is a mixing valve that mixes the heated water from the heat exchanger 11 with the cold return water from the heat load 14.
  • the outlet from the three--way valve 5 is into the pump 7.
  • the valve 5 can divert flow from the heat exchanger outlet 21 back into the pump 7 in order to recirculate water on the secondary side of the heat exchanger 11 and control primary side temperature.
  • the three-way valve 5 is a diverter valve fed with heated water from the pump 7.
  • the water can be diverted between the hot flow to the heat load 14 and the hot water to be mixed with the cold return before entering the heat exchanger 11.
  • the valve 5 can hence couple the outlet from the pump 7 to the inlet 18 for the secondary side of the heat exchanger. Again this allows for recirculation on the secondary side.
  • the arrangement of Figure 5 again uses a diverter valve as the three-way valve 5. In this case it is fed by heated water from the heat exchanger 11. The water can be diverted between the hot flow to the heat load 14 and the hot water to be mixed with the cold return before entering the pump 7. When flow is diverted via the feedback conduit in the manifold 6 then it can recirculate on the secondary side to control the primary side temperature.
  • the final alternative shown in Figure 6 has a three-way valve 5 as a mixing valve that mixes the heated water from the pump 7 with the cold return water from the heat load 14.
  • the outlet from the valve 5 is into the heat exchanger 11.
  • valve 5 is positioned far from the heat exchanger 11. This allows more space for the valve 5, and maintains the advantage of a compact arrangement- especially when a valve actuator is placed on top of the manifold as in the preferred arrangement of Figures 8 and 9 , which is discussed below.
  • valve actuator may take up the same horizontal space as the heat exchanger 11, and hence the manifold arrangement has to be extended compared to that of Figures 3 and 4 .
  • the heat exchanger apparatus is also connected to an expansion vessel 15.
  • the expansion vessel 15 may be of the type that also is the point where water is added to the system (in the same way as the water container in the car).
  • Figures 8 and 9 show a non-schematic drawing of a heat exchanger apparatus as described herein.
  • the various parts have the same reference numbers and are in the same arrangement as shown in Figure 3 , with the addition of an expansion vessel as shown in Figure 7 .
  • the pumps 7, 10 and the heat exchanger 11 occupy the same vertical space, which allows for a compact arrangement.
  • the three-way valve 5 is aligned with the pump 7 in the secondary circuit, which means that there is no need to lengthen the manifold 6 on that side.
  • the pumps 7, 10 have inlets and outlets with a vertical flow direction, and this is in parallel with the flow direction from inlet to outlet on the heat exchanger 11.
