- buildings and dwellings are more often provided with air exchange devices so that the air inside the conditioned space be replaced constantly or from time to time.
- air exchange devices are connected to the ductwork of the air conditioning system or provided with an independent ductwork.
- the main purpose of these devices is to replace air while transferring heat between the exhaust air and the incoming fresh air.
- energy is saved by pre-cooling or pre ⁇ heating the incoming fresh air with the exhaust air instead of having to fully heat or cool it while the exhaust air is drawn outside in pure waste.
- Installation of an air exchange device often requires air ducts, controls, space and labour costs in addition to the conventional air conditioning device.
- the object of the present invention is to provide a very versatile and compact unit that suitably combines an air exchange device and an air conditioning device.
- the object of the present invention is to provide a combined air exchange and air conditioning unit for conditioning air in a conditioned space, the unit comprising: an exhaust air chamber having an air outlet for connection with an air exhaust location outside the conditioned space; an exhaust blower means for drawing air from inside the exhaust air chamber through the air outlet thereof; a return air chamber having an air intake for connection with at least one air return location in the conditioning space; a supply air chamber having an air outlet for connection with at least one air supply location in the conditioned space; a supply blower means for drawing air from inside the supply air chamber through the air outlet thereof; a fresh air chamber having an air intake for connection with a fresh air location outside the conditioned space and remote from the air exhaust location; a damper means for regulating air transfers between the chambers, the damper means being movable within a position range defined between a first and a second extreme position, the chambers being connected in pairs independent from one another when the damper means is in the first or second extreme position, the first extreme position allowing a connection of the return air chamber with
- FIG. 1 is a cross-sectional view of the combined unit according to the present invention, showing the unit with no air exchange between inside and outside the conditioned space.

- FIG. 3 is a view similar to FIG. 1, showing the unit with partial air exchange between inside and outside the conditioned space.
- FIG. 4 is a simplified schematic view of the heat pump assembly according to a preferred embodiment of the present invention. The following is a list of the components found in the drawings and in the description of a preferred embodiment:
- the unit (10) is used for conditioning air in a conditioned space, such as a building, a house or even a single room.
- the unit (10) can be installed at various locations outside or inside the conditioned space. It is particularly suitable for wall mounting with the use of appropriate connecting means (14). Typical outside locations are for example roofs or walls, and typical inside locations are basements, closets, laundry rooms or garages.
- the unit (10) basically comprises a housing enclosing four chambers.
- the first chamber is an exhaust air chamber (20) having an air outlet (22) for connection with an air exhaust location outside the conditioned space.
- the connection is usually made by an air duct, but depending on where the unit (10) is located, the air outlet (22) may be already outside.
- An exhaust blower (24) is used for drawing air from inside the exhaust air chamber (20) through the air outlet (22).
- the exhaust blower (24) is preferably located inside the exhaust air chamber (20). Alternatively, one can provide the exhaust blower (24) downstream the air outlet (22) and, for example, at the end of a corresponding air duct.
- the second chamber is a return air chamber (30) having an air intake (32) for connection with at least one air return location in the conditioning space.
- the number of return locations in a building or a house is mainly depending on the size of the conditioned space and the amount of air to be conditioned.
- the return air chamber (30) can be connected to the return location by means of an air duct or the air can be directly drawn from the surroundings of the unit (10) in case the unit (10) is located inside the conditioned space.
- the third chamber is a supply air chamber (40) having an air outlet (42) for connection with at least one air supply location in the conditioned space.
- the supply air chamber (40) is where the conditioned air is sent to the conditioned space by a supply blower (44) drawing air from inside the supply air chamber (40) through the air outlet (42).
- a supply blower (44) drawing air from inside the supply air chamber (40) through the air outlet (42).
- the supply air is distributed by registers (not shown) connected to the unit (10) by branch ducts (not shown). Alternatively, the supply air can be directly sent outside the surroundings of the unit (10) in case the unit (10) is located inside the conditioned space.
- the supply blower (44) is preferably located inside the supply air chamber (40), but one can provide the supply blower (44) downstream the air outlet (42) and, for example, at the end of
- the fourth chamber is a fresh air chamber (50) having an air intake (52) for connection with a fresh air location outside the conditioned space and remote from the air exhaust location.
- the purpose of the fresh air is to replace any air drawn out of the conditioned space and, in sequence or at the same time, provide or absorb heat in a first heat exchanger (70) that is part of a heat pump means described further in the text.
- the expression "remote from the air exhaust location” does not necessary mean a far location. It means that the fresh air location should not be significantly contaminated by exhaust air that would reduce the quality of the fresh air.
- fresh air it is opposed to the term “exhaust air”, not necessarily meaning cool or air from outdoors.
- the fresh air can be drawn from an indoor location outside the conditioned space.
- the connection of the fresh air chamber (50) with the fresh air location is usually made by an air duct, but depending on where the unit (10) is located, the air intake (52) may already be outside.
- the chambers of the unit (.10) are separated from one another by inner walls (12).
- a damper means is used for regulating the air transfers between the chambers so that each chamber is communicating with at least another, thereby allowing the air to flow within the unit (10).
- the damper means preferably comprises a revolving plate (60) movable around the central axis (62) by an actuating means, such as an electric motor and any other suitable actuating mechanism.
- the plate (60) has two edges (64) parallel to the central axis that are pressing against walls (12) separating the chambers at extreme positions.
- the plate (60) is movable within a position range defined between a first and a second extreme position.
- the chambers are connected in pairs independent from one another when the plate (60) is in the fir ⁇ t or second extreme position. It is of course suitable that the junction of the edges (64) with the walls (12) be substantially air tight.
- the first extreme position is defined as the position allowing a connection of the return air chamber (30) with the supply air chamber (40) and a connection of the fresh air chamber (50) with the exhaust air chamber (20). There is no air exchange between inside and outside of the conditioned space in that position.
- the second extreme position is defined as the position allowing a connection of the return air chamber (30) with the exhaust air chamber (20) and a connection of the fresh air chamber (50) with the supply air chamber (40). There is a full air exchange between the interior and the exterior of the conditioned space in that position.
- FIG. 3 shows an example of an intermediary position.
- the unit (10) features a heat pump.
- the heat pump is used for reversibly transferring heat between air to be drawn by the exhaust blower (24) and air to be drawn by the supply blower (44).
- a first heat exchanger (70) for exchanging heat with air to be drawn by the exhaust blower (24)
- a second heat exchanger (74) provided for exchanging heat with air to be drawn by the supply blower (44).
- the first heat exchanger (70) is obliquely disposed inside the exhaust air chamber (20) and the second heat exchanger (74) is obliquely disposed inside the supply air chamber (40).
- the oblique disposition is suitable for reducing the size of the combined unit (10).
- a refrigerant circuit is provided between the first and the second heat exchangers (70,74).
- the first heat exchanger (70) comprises a first refrigerant coil (72) connected to other components of the heat pump as shown in FIG. 4.
- the second heat exchanger (74) comprises a second refrigerant coil (76).
- a compressor (78), preferably located inside the fresh air chamber (50), is used for compressing a compressible refrigerant.
- the compressor (78) is set between the exchangers (70,74) and an expansion valve (82) is set on the other side, as shown in FIG. 4.
- the expansion valve (82) may be substituted for capillary tubes, for instance.
- the expansion valve (82) is used for lowering pressure of the refrigerant between the exchangers (70,74).
- the components are connected together by a refrigerant tubing (86).
- the refrigerant is compressed by the compressor (78), which then increases its pressure and temperature for subsequently releasing heat in one of the exchangers (70,74).
- the expansion valve (82) is used for lowering its pressure and the temperature for subsequently absorbing heat in the other exchangers (70,74).
- a first valve (80) is provided for selectively directing the refrigerant compressed in the compressor (78) to either the first heat exchanger (70) or the second heat exchanger.
- a second valve (84) synchronized with the first valve (80) may be provided if the expansion valve (82), or the like, is not reversible. The second valve (84) is then used for selectively directing the refrigerant from the first heat exchanger (70) through the expansion valve (82) and then to the second heat exchanger (74), or from the second heat exchanger (74) through the expansion valve (82) and then to the first heat exchanger (70).
- the second valve (84) is said to be synchronized with the first valve (80) to prevent that one of the exchangers (70,74) be isolated from the circuit.
- the first and the second valve (80,84) may be provided in a single device (not shown), such as a 4-way valve.
- Control means (90) are used for controlling the actuating means (66) and the heat pump. There are many possible embodiments for the control means (90), ranging from the manual controls to the fully automated controls using a computer.
- the combined unit (10) may work under many different modes.
- the first mode is the heating mode as used, for instance, during winter.
- the first heat exchanger (70) is the evaporator, receiving the refrigerant from the expansion valve (82), and the second heat exchanger (74) is the condenser.
- the plate (60) is positioned like in FIG. 1, the unit (10) acts as a regular heat pump that takes the heat in the outside air and transfers it to the air returning to the conditioned space.
- An additional heating element such as an electric heating coil (not shown) , may be added for heating the return air during very cold weather.
- the heat of the exhaust air coming from inside the conditioned space will be recovered and transferred back to the supply air, without reversing the cycle and thus allowing a better stability of the temperature of the return air.
- the first heat exchanger (70) is the condenser and the second heat exchanger (74) is the evaporator.
- the unit (10) acts as a regular air conditioning unit for cooling and dehumidifying the air returning to the conditioned space.
- means for collecting and evacuating water condensing on the evaporator are provided, as apparent to a person skilled in the art.
- the unit (10) may go to a mode called "free-cooling" where the compres ⁇ or (78) is stopped and where there is a full air exchange, as in FIG. 2.
- the free-cooling occurs if the fresh air is below 72°C (22°C).
- the unit (10) may be used for controlling the humidity of the conditioned space under certain conditions.
- the air is dehumidified by the second heat exchanger (74), then acting as the evaporator.
- the amount of air exchanged between inside and outside of the conditioned spaced will have an impact on the humidity level whenever the characteristics of the outside and inside air is not the same.
- One of the other possible modes is a neutral mode where there is no air exchange and where only the return air blower (44) is operated. This mode is used for instance after air exchange occurred during a given period of time.
- control means (90) compri ⁇ es an adjustable timer (not shown) for controlling the time and the frequency of the air exchange. It is also suitable to provide a manual control for overriding the signals from the timer or to select one of the operating modes, for instance: heating only; heating with air exchange; - cooling only; cooling with air exchange; air exchange only (with selection winter/summer); free-cooling; ventilation only; - fully automated control.
- the unit (10) may be provided with a first air filter (34) set downstream the air intake (32) of the return air chamber (30) for filtering dust or the like.
- a second air filter (54) may also be set downstream the air intake (52) of the fresh air chamber (50) for filtering the fresh air.
- a first air bypass assembly (100) connected to the return air chamber (30).
- the first air bypass assembly (100) may be controlled by the control means (90) or set manually.
- the first air bypass assembly (100) comprises a first air intake shutter
- the first air recovery mean ⁇ (104) is for example an actuated damper connected to an air duct for drawing bypa ⁇ air from a location in ⁇ ide the conditioned space and having distinctive characteristics. For instance, it may be suitable during summer to draw air from the basement of a house because it is much cooler than the other sections of the conditioned space. In winter, it may be suitable to draw air from warm locations such as a laundry room. The bypass air may even come from more than one source. As another example, the exhaust air from the bathroom may be used in winter when the unit (10) is in full air exchange, as in FIG. 2.
- a second air bypass assembly (110) may also be connected to the fresh air chamber (50).
- the function of the second air bypass as ⁇ embly (110) is very similar to the first air bypas ⁇ assembly (100).
- the second air bypass assembly (110) may be controlled by the control means (90) or set manually.
- the second air bypass as ⁇ embly (110) comprise ⁇ a ⁇ econd air intake shutter (112) for partially closing the air intake (52) of the fresh air chamber (50).
- a second air recovery means (114) is proportionally providing bypass air inside the fresh air chamber (50).
