AN AIR HANDLING APPARATUS

Description

[0001] The present invention relates to an air handling apparatus and in particular to an air handling apparatus used in a ventilating, heating and cooling system according to the preamble of claim 1. Such a system is known from US-A-6 223 545.

[0002] EP 0808441 discloses an air heating and heat recovery ventilation system with one or more solar panels of the type which transmit incident solar radiation into the housing, a solar radiation absorber in the housing and air inlet and outlet ports to enable air to be circulated through the panel to collect heat from the panel. The system includes an air handling apparatus which comprises an air-to-water heat exchanger and means for forcing the heated air from the solar panels through the heat exchanger, thereby transferring heat to water in the domestic hot water supply system and forcing warm air emerging from the heat exchanger to flow around the house. As clearly seen in Figure 7 of EP 0808441 the air handling apparatus comprises four distinct and separate chambers. The air handling apparatus described therein does not respond quickly or easily to changes in temperature or indeed in response to alterations of the control system governing the air heating and heat recovery ventilation system.

[0003] The present invention seeks to alleviate the problems associated with known air handling apparatuses.

[0004] Accordingly the present invention provides an air handling apparatus as claimed in claim 1.

[0005] The features of the invention will be apparent from a consideration of the attached claims 1 to 15.

[0006] Preferably the inlet port attached to the first heat exchanger is connected to the outlet port connected to the second fan. Likewise it is preferable that the inlet port attached to the second heat exchanger is connected to the outlet port connected to the first fan.

[0007] Conveniently the separation means comprises a damper rotatable around a central axis point between the first and second position.

[0008] In the first position, a single loop is formed in which fluid flows through the first fan and fluid outlet port. Fluid re-enters the air handling apparatus through fluid inlet port and passes through the first heat exchanger through the second fan and fluid outlet port. Fluid subsequently re-enters the air handling apparatus 1 again through the fluid inlet port attached to the second heat exchanger.

[0009] The second position forms two distinct closed loops. In the first loop fluid flows through the second fan and fluid outlet re-entering the air handling apparatus through fluid inlet port attached to the second heat exchanger. The second loop comprises fluid exiting the air handling apparatus though the first fan and fluid outlet port subsequently re-entering through the fluid inlet port attached to the first heat exchanger.

[0010] Ideally the damper is operated by a single motor.

[0011] Preferably the air handling apparatus further comprises one or more filters. Conveniently the air handling apparatus uses a plurality of different sized filters. In practice it is preferable to use larger filters as this increases the length of time a filter can operate effectively between filter changes.

[0012] The components of the air handling apparatus are placed in a plurality of separate interconnecting compartments for ease of handling and flexibility. The compartments comprise a first and second fan compartment and a central compartment. The sizes of each compartment being restricted to ensure that each will fit through a standard attic trap door. It will of course be appreciated that the compartments of the invention are not limited to this size and indeed any size can be used.

[0013] Each fan compartment attaches to either side of the central compartment. Ideally the central compartment contains the separation means and at least two heat exchangers.

[0014] Conveniently the fan compartments are sufficiently large to minimise pressure across each of the fans thus allowing the fans to run more efficiently.

[0015] Ideally each compartment contains all further necessary control means and connections required for interfacing the air handling apparatus with external devices.

[0016] Optionally the air handling apparatus can be connected to one or more of solar panels, domestic hot water cylinders, heat recovery ventilation units and/or a further energy source such as a heat pump or boiler.

[0017] Optionally the first fan compartment is large enough to accommodate a selection of different sized connections which act as a manifold for the distribution of air to the house.

[0018] Optionally the second fan box is large enough to accommodate a selection of different sized connections which act as a manifold for the distribution of air to the solar panels. Typically up to three pairs of air solar panels are connected to the manifold. It is of course appreciated that the number of solar panels connected to the system can be increased further by increasing the size of the fan motors.

[0019] Conveniently the air handling apparatus when connected to external devices such as solar panels, domestic hot water cylinder and a heat recovery ventilation unit forms an integrated ventilation heating and cooling system.

[0020] Preferably the integrated ventilation heating and cooling system further comprises a control system which enables the air handling apparatus to respond to external commands. Optionally the control system could further enable the air handling apparatus to automatically respond to pre-set commands such as temperature inputs.

[0021] Optionally the heat exchangers are air to water heat exchangers.

[0022] Conveniently the heat exchanger of the air handling apparatus supplies heat to the ventilation air and/or to the domestic hot water cylinder. Optionally the second heat exchanger is connected to an external heat source for example a boiler or a heat pump, which acts as the main heat source to heat the building.

[0023] Ideally the air handling apparatus can operate with either liquid based solar panels or air based solar panels. Conveniently the heat exchanger operates in opposite directions depending on whether the solar panel is liquid or air based.

[0024] Ideally the first and second fans in the air handling apparatus are used to circulate the air in the solar panel loop or as the main fan for ventilating or heating the house respectively. Conveniently the two fans can run independently as described above or in series. Preferably when the fans are operating in series the ventilation air passes through the solar panel loop and then on to the house. Ideally in this mode the solar panels can be used to heat both the domestic hot water and the house or alternatively just the house in accordance with a defined control strategy. Conveniently the fans are interchangeable such that either fan can to circulate the air in the solar panel loop or operate as the main fan for ventilating or heating the house.

[0025] Conveniently the fans in the air handling apparatus can operate on either DC or AC.

[0026] Optionally the air handling apparatus can also be connected to a heat recovery unit, which will preheat the incoming air and therefore add to the overall efficiency of the system.

[0027] Ideally the most appropriate location for an air handling apparatus in a dwelling house is in the attic space. This is particularly efficient if some of the energy is being generated by solar panels as the air handling apparatus would then be adjacent to the solar panels on the roof.

[0028] The invention is particularly illustrated in the accompanying drawings which show, by way of example only, embodiments of the air handling apparatus according to the invention together with embodiments of a ventilating, heating and cooling system according to the invention.

Figure 12 is a perspective drawing illustrating the position of a ventilating, heating and cooling system of the invention within a house

[0030] Referring now to Figure 1 there is shown a schematic drawing illustrating a first embodiment of the heating and ventilating system of the invention in which the air handling apparatus 1 is connected to two energy supply sources, namely solar panels 10 and a conventional boiler 12. Energy generated by the solar panels 10 is transferred by the air handling apparatus 1 to the domestic hot water cylinder 11 in a first closed loop. Whilst energy generated by the boiler 12 is used to heat the ventilation air 4 of the house thereby heating the house. The air circulated around the house is recovered at 5 and passed through a heat recovery unit 3. There are a number of operational options at the heat recovery unit 3. In a first option circulated air is expelled and fresh air is absorbed 2 which is then heated using both the heat recovered through the heat recovery unit 3 and the boiler 12 and then circulated through the air handling apparatus 1 around the house. Alternatively some or all of the circulated air re-enters the air handling apparatus 1 via the heat recovery unit 3, this air is then re-circulated. If necessary some fresh air 2 is also circulated into the air handling apparatus 1 to ensure oxygen levels remain static.

[0031] Figure 2 illustrates a second embodiment of the heating and ventilating system of the invention however in this embodiment a heat pump 13 is used to change the temperature of the air circulated to the air handling apparatus 1 which is subsequently circulated around the house. In this scenario either an adsorption or absorption heat pump can be used which either could heat or cool the air via the air handling apparatus 1.

[0032] Turning now to Figure 3 there is shown a first embodiment of the air handling apparatus 1 of the invention. The air handling apparatus 1 comprises two heat exchangers 23 and 24 and two fans 20 and 21. The first heat exchanger 23 is connected to a fluid inlet port 102, whilst the second heat exchanger 24 is connected to a fluid inlet port z The first fan 20 is connected to a fluid outlet port 101 and the second fan 21 is connected to a second fluid outlet port 4. The fluid paths are determined by the orientation of the separation means 26. The separation means 26 comprises a damper rotatable about a central axis point. It has two positions, A or B.

[0033] Position 'A' forms a single loop in which the fluid flows through fan 21 and subsequently through fluid outlet port 4. The fluid re-enters the air handling apparatus 1 through fluid inlet port 103. The connections between fluid outlet port 4 and fluid inlet port 103 are not shown. Fluid then passes through the heat exchanger 24, fan 20 and fluid outlet port 101. Fluid re-enters the air handling apparatus 1 again through fluid inlet port 102 and heat exchanger 23 to start another cycle. As before the connections between fluid outlet port 101 and fluid inlet port 102 are not shown.

[0034] In contrast position 'B' forms two distinct closed loops. In the first loop fluid flows through fan 21 and fluid outlet port 4 re-entering the air handling apparatus 1 through fluid inlet port 103. Fluid then passes through heat exchanger 24 and into fan 21 starting the cycle again. The second loop comprises fluid exiting the air handling apparatus 1 though fan 20 and fluid outlet port 101 subsequently re-entering through fluid inlet port 102 and heat exchanger 23.

[0035] In a first example the fluid inlet and outlet ports 102 and 101 could be connected to solar panels thus forming a closed solar loop. Further inlet and outlet ports can be connected to the domestic hot water cylinder enabling heating of domestic hot water using solar energy. Fluid inlet and outlet ports 4 and 103 could be connected to a house ventilation system which is further connected to another energy source. Thus in position 'B' the house can be simultaneously ventilated and/or heated using a first energy source whilst domestic hot water can be heated using solar energy.

[0036] It is clearly seen in Figure 3 that the air handling apparatus 1 comprises a single unit. However it is appreciated.that the size of the components within air handling apparatus 1 could be quite large depending on the actual requirements of the device. In practice the actual size of the air handling apparatus 1 is restricted so that it will fit through a standard attic trap door as the most appropriate location for the air handling apparatus 1 is in the attic space adjacent to solar panels 10 on the roof, as seen in Figure 12. Consequently the air handling apparatus 1 according to the invention comprises three interconnecting compartments for ease of handling and flexibility. The first and second compartment comprising each of the fans 21 and 20, and a third compartment comprising the heat exchangers 23 and 24 and the damper mechanism 26 whereby the first and second compartments attach to either side of the third compartment. Using interconnecting compartments enables the use of larger fan sections which has the advantage of minimising pressure across the fans 21 and 22 thus allowing the fans 21 and 22 to run more efficiently.

[0037] The external surfaces of the air handling apparatus 1 and the first and second compartments further contain the controllers and connections for interfacing the air handling apparatus 1 with external devices.

[0038] Referring now to Figures 4 to 11 there is shown a number of different embodiments of an integrated ventilation heating and cooling system using the air handling apparatus 1 of the invention.

[0039] In Figure 4 there is shown a damper of the air handling apparatus 1 in a first orientation, position 'B' as described above. Fluid flows through the system as outlined above. The first loop corresponds to the ventilation/heating system of the house 6. Thus fluid flows through fan 21 and fluid outlet port 4 around the house 6. The air circulated around the house 6 is collected and passes through a heat recovery unit 3, fluid from the heat recovery unit and some air 2 enter the air to water heat exchanger 24 through fluid inlet port 103. Air is reheated at the heat exchanger 24 before being circulated around the house 6 again.

[0040] The second loop corresponds to the solar panel loop wherein fluid exiting the air handling apparatus 1 through fan 20 and fluid outlet port 101 passes through solar panels 10 before re-entering the air handling apparatus 1 through fluid inlet port 102 and heat exchanger 23. The domestic hot water cylinder 11 is connected to heat exchanger 23 and fluid is pumped between the heat exchanger 23 and the domestic hot water cylinder 11 using pump 110. Solar energy is transferred from the solar panels 10 to the system for heating the domestic hot water via heat exchanger 23. Figure 4 shows how the air handling apparatus 1 and system of the invention allows simultaneous heating of the domestic hot water using solar power and ventilation or heating of the house 6.

[0041] Figure 5 shows a second orientation of the damper of the air handling apparatus 1 in position 'A' showing how the house can be heated using solar panels 10 as the sole source of heat. Heat is collected by the heat exchanger 23 from solar panels 10 which is then transferred to the fluid and pumped around the house 6 through fan 21. Optionally fluid can be recirculated directly to heat exchanger 24 as indicated by the dotted line, or can re-enter the heat exchanger 24 after passing through a heat recovery unit 3, the fluid then passes through fan 20 and re-enters the solar panels 10.

[0042] In Figure 6 the damper 26 is in the 'B' position however fluid is being circulated through one chamber only. A mix of re-circulated and fresh air is heated using boiler 12. Heated air is then being circulated around the house 6 as outlined previously. This embodiment does not fall under the scope of the claims.

[0043] Figure 7 shows the damper 26 of the air handling apparatus 1 in the 'B' position and fluid is circulating through both chambers. In the first chamber solar power is being used to heat domestic hot water whilst in the second chamber of the air handling apparatus heat is being extracted from the air using the heat exchanger 24 and the heat pump 13. The cooled air is being circulated through the house 6.

[0044] In Figure 8 the damper is in the 'B' position and fluid is being circulated through one chamber only. Air is being heated using the heat exchanger 24 and either a heat pump 13 or boiler 12. Heated air is then being circulated around the house 6. This embodiment does not fall under the scope of the claims.

[0045] Figure 9 is similar to Figure 4 however the solar panel 10 is a dry solar panel thus operation of the heat exchanger 23 is reversed, i.e. hot air from the solar panel heats the water in heat exchanger 23 which in turn heats the water in the domestic hot water cylinder 11.

[0046] Figure 10 is a schematic drawing illustrating how the performance of a wet solar panel is improved as the operating range of the solar panel is increased whilst simultaneously ventilating the house 6. The solar panel 10 is directly connected to the domestic hot water cylinder 11. Fluid flow is maintained around this loop using a pump 110 and two port motorised valve 111. The solar panel 10 is also connected to the heat exchanger 23 via a mixing valve 113. The water is returned from the heat exchanger 23 to the solar panel 10 via a two port valve 111.

[0047] Figure 11 shows is similar to figure 10 illustrating a wet solar panel having improved operating range however the damper 26 of the air handling apparatus 1 is in the 'A' position thus indicating how the energy generated by a solar panel can be used to heat domestic hot water in addition to ventilating or heating a house 6.

[0048] Figure 12 is a perspective drawing illustrating the position of a ventilating, heating and cooling system of the invention within a house.

[0049] It is to be understood that the invention is not limited to the specific details described herein which are given by way of example only and that various modifications and alterations are possible without departing from the scope of the invention as identified in the appended claims.
