Description
AIR DEHUMIDIFYING APPARATUS
TECHNICAL FIELD OF THE INVENTION
This invention relates to air dehumidifying apparatus which can be installed in any room provided with a cold water supply such as a bathroom, shower room, swimming pool, laundry etc.
BACKGROUND
In bathrooms condensation and steam caused by showers is a common problem. When running a hot shower water readily evaporates into the heated air in the vicinity of the shower. When this warm moist air meets colder air elsewhere in the room droplets of water condense out forming a fog or mist. In addition the dewpoint of the warm air is often above the temperature of other surfaces in the room such as mirrors, pipes, walls, and windows, which causes water to condense out on these cold surfaces.
One solution to this problem is to suck the air out of the room taking the moisture with it and replace it with cooler dryer air from another part of the building, or simply open a window and allow air in from outside. This is wasteful of energy because heat is lost from the building and extractor fans have to run for some time after the shower to clear the moisture from the room. Moreover, this is somewhat ineffective because all that happens is that moist air is diluted with less moist air. Another consideration is that if moist air is allowed to escape into the rest of the building this can lead to long-term damp problems and possible health consequences.
Conventional dehumidifiers are very effective at removing moisture, and there is no heat loss from the building, but the initial cost is considerable, and the ongoing running cost of a vapour compression cooling system is not insignificant.
CA 2 266 268 A attempts to tackle this problem by circulating the moist air through a heat exchanger. A cold surface of the heat exchanger condenses the moisture and a hot surface warms the air after the moisture is removed. The cold surface is achieved by passing cold water through the heat exchanger before passing through a water heater. The hot surface is provided by passing the hot water back through the heat exchanger. This arrangement is quite complex, and is not easy to install since it is necessary to plumb the heat exchanger into both the hot and the cold water supplies.
The present invention seeks to provide a new and inventive form of air dehumidifying apparatus for use in a room provided with a cold water supply, which is easy to install, has a low running cost, and is relatively efficient having a low heat loss.
SUMMARY OF THE INVENTION
The present invention proposes air dehumidifying apparatus for use in a room provided with a cold water supply, which includes: -an air inlet A for receiving air from the room; -an air outlet B from which air is returned to the room; -an air-to-air heat exchanger having a first flow path with an inlet C and an outlet D, and a second flow path with an inlet E and an outlet F, inlet C being connected to inlet A and outlet F being connected to outlet B; and -an air-to-water heat exchanger having an air flow path with an inlet G and an outlet H, and a water flow path, inlet G being connected to outlet D and outlet H being connected to inlet E, and the air flow path having drainage means for collecting condensate; the arrangement being such that, in use, the water flow path is connected to the cold water supply, and incoming moist air passes through the first flow path in which it is pre-cooled before passing through the air-to-water heat exchanger wherein the air is cooled by water flowing through the water flow path, and the cooled air then passes through the second flow path to be warmed by air flowing through the first flow path before being returned to the room.
BRIEF DESCRIPTION OF THE DRAWINGS
The following description and the accompanying drawings referred to therein are included by way of non-limiting example in order to illustrate how the invention may be put into practice. In the drawings: FiQure 1 is a schematic diagram of dehumidifying apparatus in accordance with the invention; Figures 2 to 4 show various enhancements of the dehumidifying apparatus shown in Fig. 1; Fiçure 5 is general view of a shower room showing one practical application of the apparatus; and Fiq,jre 6 is a similar view to Fig. 5 showing a different method of installation.
DETAILED DESCRIPTION OF THE DRAWINGS
The basic principle of the air dehumidifying apparatus of the present invention can be understood by referring to Fig. 1. Practical applications of the apparatus will be described below. The apparatus includes an air-to-air heat exchanger 10 and an air-to-water heat exchanger 20. The two heat exchangers are shown as separate items for clarity of explanation, although it will be appreciated that in practice they may be combined into a single unit.
Moist air enters the apparatus through an air inlet A which receives air from a room such as a bathroom, shower room or laundry. After passing through the apparatus dry air leaves the apparatus through an air outlet B and is returned to the room.
The air-to-air heat exchanger 10 has a first flow path 12 with an inlet C and an outlet D, and a second flow path 14 with an inlet E and an outlet F, the two flow paths being in mutual heat-exchange relationship. Inlet C is connected to inlet A to receive the warm moist air, and outlet F is connected to outlet B. The air-to-water heat exchanger 20 has an air flow path 22 and a water flow path 24 in mutual heat-exchange relationship. By way of example, a conventional finned coil heat exchanger may be used in which the water flows through a heat-conductive tube while the air passes across heat-conductive fins attached to the tube. The air flow path 22 has an inlet G and an outlet H, and a water flow path 24 similarly has a water inlet I and a water outlet J. Air inlet G is connected to outlet D of the heat exchanger and air outlet H is connected to inlet E of the air-to-air heat exchanger.
The water inlet and outlets I and J are plumbed into an adjacent cold water supply so that cold water flows through the flow path 24 when the apparatus is in use, e.g. to supply a shower.
In use of the apparatus the removal of moisture from air passing through the dehumidifier takes place in three phases, as follows: I) Incoming warm moist air passes through the first flow path 12 in which the air is pre-cooled.
II) The pre-cooled air then travels through path 22 of the air-to-water heat exchanger 20 in which the air is cooled by water flowing through the water flow path 24. As the air cools below its dewpoint the moisture condenses on the fins of the heat exchanger.
Ill) The cooled dehumidified air then passes through the second flow path 14 wherein the air is warmed by air flowing through the first flow path 12 before being returned to the room.
The air-to-air heat exchanger 10 thus provides a dual function of pre-cooling the incoming moist air and re-heating the outgoing dry air. Such pre-cooling preconditions the air to increase moisture removal.
In practice the air is moved through the device by a fan 30, which could be positioned at the air inlet A as in Fig.s 2 and 4. In some situations it might be preferable to position an electric fan at the air outlet B as in Fig. 3, e.g. to keep the fan away from the moist environment around the inlet A. The fan may be controlled by a flow switch or other sensor which can detect flow of cold water through the flow path 24. In order to optimise the energy efficiency of the apparatus it might be advantageous to delay startup of the fan and/or keep the fan running for a period after the flow of water stops.
The air flow path through the air-water heat exchanger 20 will also be provided with drainage means for collecting condensate such as a drip tray 26, which is shown in Fig.s 2 to 4. The collected water may be disposed of via a shower drain, or piped to a waste outlet etc. In some situations it might be desirable to remove some of the air rather than returning it to the room, in which case an extraction duct K can be connected between the outlet H of the heat exchanger 20 and the inlet E of the heat exchanger 10, as shown in Fig. 4. Cold air is thus expelled from the room thus minimising heat loss. A proportion of the air preferably still passes through the air-air heat exchanger 10 to ensure that the incoming air is pre-cooled, as described above.
The performance of the apparatus is improved by separating the inlet A from the outlet B. When used in the vicinity of a shower 50 as shown in Fig. 5, the air is preferably drawn from the shower area and returned to another part of the room. This creates an airflow 57 moving towards the shower, which helps to retain moist steamy air within the shower area.
Fig. 5 shows an embodiment of the apparatus which is mounted on a ceiling 58. However, a version of the dehumidifer could also be mounted above ceiling 58 in a roof void or other space, as shown in Fig. 6.
Whilst the above description places emphasis on the areas which are believed to be new and addresses specific problems which have been identified, it is intended that the features disclosed herein may be used in any combination which is capable of providing a new and useful advance in the art.
