Abstract
The heating unit 10 is adapted for connection to an externally heated fluid supply, such as hot water, received via a thermostatic control valve 22. The heating unit comprises: a heat exchanger 12 arranged to be supplied with heated fluid from the supply; a powered convection means, such as an electric fan 11; and a low temperature cut-out (LTC) device 13 arranged to control the supply of power to the convection means. The LTC device operates at a cut-out temperature that is below the temperature of the heat exchanger when being supplied with heated fluid. The LTC device may detect the temperature of fluid in the heat exchanger using a temperature sensor 14 and be arranged to disconnect power to the fan when the temperature of heated fluid in the heat exchanger falls below 40°C. The heating unit may include a housing having an air inlet 17 and outlet 18, the fan drawing air downwards against natural convection. A fluid inlet 15 and outlet 16 of the heat exchanger may be on opposing sides of the heating unit so that the heating unit may be substituted in place of a conventional panel radiator in a central heating system. A method of controlling the heating unit is also claimed.
Description
Fan Convector Heating Unit This invention relates to a fan convector heating unit. In particular, the invention relates to an improved fan convector heating unit and method for controlling a fan convector unit.
Fan convector heating units generally comprise a heat exchanger and an electric fan, both housed within the heating unit. Typically, the central heating system of a building is utilised to feed the heat exchanger with heated water, and ambient air from the room is drawn through the heating unit by the electric fan and across the heat exchanger, thereby heating the air before it is expelled back out into the room. Essentially, the fan provides forced convection.
An advantage of fan convector heating units over conventional panel radiators is that they offer a faster and more efficient means of heating the ambient air in a room. In particular, they do not require their water supply to be heated to the high temperatures required by conventional panel radiators, and are therefore suitable for use with systems where the hot water is generated from renewable sources, which tend to be low energy systems.
Conventional panel radiators are often used in combination with a thermostatic control valve (TCV), which is sometimes called a thermostatic radiator valve (TRy). A thermostatic control valve is configured to open and close, to control the flow of hot water into heating units, panel radiators, or similar, depending on the ambient air temperature detected by the thermostatic control valve relative to a desired temperature setting of the thermostatic control valve.
A thermostatic control valve generally has several selectable settings, each of which corresponds to a temperature at which the thermostatic control valve will close, thereby stopping the supply of hot water to the radiator.
Typically, the lowest setting of a thermostatic control valve is a "frost protection" setting, at which the thermostatic control valve will typically close when it detects an ambient temperature of around 6-8°C, whereas at the highest setting the thermostatic control valve may not close until it detects an ambient air temperature of 26-29°C.
In existing tan convector heating units, the electric fan is usually provided with a thermostat to control it. The electric fan thus only operates to draw ambient air through the heating unit, and across the heat exchanger housed within it, when the thermostat detects that the ambient air temperature is below a temperature at which the electric fan thermostat is set.
A problem with such fan convector heating units is that heated fluid is continuously passing through the heat exchanger. Therefore, ambient air continues to be heated by natural convection after the fan thermostat has stopped the fan from actively drawing it through the heating unit. This makes it difficult to maintain a constant temperature in a room.
EP-A-0837288 has attempted to address this problem by providing a fan convector with adjustable deflector elements, which are controlled by a thermostat to open and close to stop hot-air currents generated by natural convection.
It is a principal aim of the present invention to provide an improved apparatus and method for controlling ambient room temperatures.
According to this invention, there is provided a method for controlling a heating unit having a powered convection means arranged to draw ambient air across a heat exchanger housed within the heating unit and supplied with externally heated fluid, the method comprising the steps of: -controlling the supply of externally heated fluid to the heat exchanger with a thermostatic control valve (TCV); -controlling the supply of power to the convection means with a low temperature cut-out (LTC) device; and -setting the cut-out temperature of the LTC device to be below the temperature of the heat exchanger when the TCV is open, such that, when the TCV closes, the convection means continues to draw ambient air across the heat exchanger until the temperature of the heat exchanger reaches the cut-out temperature set for the LTC device.
The present invention therefore provides a simple yet effective method for preventing natural convection of ambient air, thereby allowing improved control of the ambient room temperature.
Power is supplied to the convection means via a low temperature cut-out device configured to cut the supply of power to the convection means at a "cut-out temperature", which is a temperature below the temperature of the heat exchanger when the thermostatic control valve is open and externally heated fluid, such as water, is being supplied to the heat exchanger. A thermostatic control valve, used in conjunction with the present invention, when set to the determined comfort level (temperature) for the roam that is to be heated, will stop the flow of externally heated fluid through the heat exchanger when the required room temperature is reached. The powered convection means will continue to run until it has cooled the now static fluid retained in the heat exchanger to below the cut-out temperature, at which point the low temperature cut-out device stops the supply of power to the powered convection means. As the heat exchanger, and fluid remaining therein, has been blown cold, little or no natural convection occurs.
The heat exchanger will remain in this state until the thermostatic control valve opens again when it detects that the room in which the heating unit is situated, according to its setting, requires more heat. The externally heated fluid is then allowed to flow through the heat exchanger again, heating it to a temperature that switches on the low temperature cut-out device once more so that the convection means can supply heated air to the room.
In other words, after a thermostatic control valve, which connects the heating unit of the present invention to a central heating system, or similar, closes to stop the supply of externally heated fluid to the heat exchanger, the convection means continues to operate, thereby cooling the heat exchanger and fluid retained therein, until the cut-out temperature is reached and the convection means is stopped. At this point, the temperature of the heat exchanger is sufficiently cool that natural convection will not occur, or at least not to a degree that the ambient air could be heated sufficiently to affect the temperature of the room. Thus, it is not necessary to prevent ambient air from moving across the heat exchanger to avoid natural convection, as the heat exchanger will be sufficiently cooled that it will not significantly heat any ambient air.
Preferably, the cut-out temperature is below about 40°C, which is considered to be sufficiently cool that little or no natural convection will occur.
Furthermore, any temperature below 40°C is below the temperature of the heat exchanger when externally heated fluid is passing through it, wherein externally heated water being supplied to the heat exchanger is typically at a temperature in the range of 45°C to 75°C.
The cut-out temperature setting will depend on the temperature of the externally heated water of the central heating system that the heating unit is to be used with, since the externally heated water heats the heat exchanger when the thermostatic control valve is open. A temperature of about 30°C is a preferred setting as this is significantly lower than the temperature of the externally heated water being supplied to the heat exchanger. However, a temperature anywhere between about 30°C and about 40°C may also be suitable, although a lower setting is also possible.
The cut-out temperature should be set to a temperature that is below the temperature of the heat exchanger when the thermostatic control valve is open and externally heated fluid is heating it. This will enable the convection means to continue to draw ambient air across the heat exchanger after the thermostatic control valve has closed, thereby cooling the heat exchanger and fluid retained therein.
Preferably, the convection means and heat exchanger are arranged within the heating unit such that ambient air is drawn across the heat exchanger and expelled towards the base of the heating unit. Advantageously, this arrangement helps to eliminate drafts in a room when the heating unit is positioned not far above the floor of the room, as the heated air exits the heating unit near to the floor and slowly rises as it drifts away from the heating unit, thereby creating a thermal curtain.
According to a second but closely related aspect of this invention there is provided a heating unit adapted for connection to an externally heated water supply via a thermostatic control valve (TCV), comprising: -a heat exchanger housed within the heating unit and arranged to be supplied with externally heated fluid; -a powered convection means arranged to draw ambient air across the heat exchanger; and -a low temperature cut-out (LTC) device arranged to control the supply of power to the convection means, wherein the LTC device is configured to operate at a cut-out temperature that is below the temperature of the heat exchanger when being supplied with externally heated water.
Using a low temperature cut-out device to control the supply of power to the convection means allows the present invention to take advantage of the functionality provided by an external thermostatic control valve of the central heating system. In doing so, the requirement for a thermostat to be provided on the heating unit itself to control the fan is eliminated.
Furthermore, the low temperature cut-out device can be set to a temperature which allows the convection means to cool the heat exchanger after the supply of heated water to the heat exchanger has been stopped by the thermostatic control valve. This prevents natural convection occurring without requiring the complex, and hence more expensive, arrangements of existing fan convector heating units.
Preferably, the heating unit further comprises a housing having an air inlet for ambient air, and an air outlet for heated air that has been passed across the heat exchanger by the convection means. The air inlet and air outlet are preferably arranged such that an air passageway is provided through a housing of the heating unit, wherein the heat exchanger is situated within the air passageway. Preferably, the air outlet is provided towards the base of the heating unit.
As mentioned above, the cut-out temperature of the LTC device is, preferably, below about 40°C, which is considered to be sufficiently cool that little or no natural convection will occur.
Preferably, the heat exchanger has a fluid inlet provided on a first side of the heating unit for and a fluid outlet provided on a second side of the heating unit. Advantageously, this arrangement allows the heating unit of the present invention to be easily substituted for a conventional panel radiator in a domestic setting, or similar.
Preferably, a power cable for the convection means enters the housing of the heating unit towards the first side of the housing, which keeps the power cable away from the fluid outlet, which may be provided with a bleed valve, or similar.
Preferably, the powered convection means is an electric fan.
By way of example only, a specific embodiment of the apparatus of the invention and method of operation will now be described in detail. Reference is made to the accompanying drawing in Figure 1, which shows a heating unit according to the present invention, installed as part of a typical central heating system, which system uses a thermostatic control valve to control the supply of externally heated water to the heating unit.
In Figure 1, a heating unit according to the present invention is generally indicated 10. A powered convection means 11 and a heat exchanger 12 are housed within the heating unit 10. In this example, the convection means is an electric fan 11.
The electric fan 11 is powered via a low temperature cut-out (LTC) device 13, which is arranged to detect the temperature of the heat exchanger 12 using a sensor 14, and to only allow power to be supplied to the electric fan 11 when the temperature of the heat exchanger 12, detected by the sensor 14, is above a predetermined value, referred to herein as the cut-out temperature.
The heat exchanger 12 is adapted to be supplied with externally heated water from a central heating system in a domestic or commercial setting. The heat exchanger has a fluid inlet 15, positioned on a first side of the heating unit 10, to receive hot water from the central heating system, and a fluid outlet 16, positioned on a second side of the heating unit 10, as shown in Figure 1, to return the hot water to the central heating system.
The heating unit 10 comprises a housing 25, which contains the various components of the heating unit 10. The housing 25 has an air inlet 17, positioned towards the top of the heating unit 10, and an air outlet 18, preferably positioned towards the bottom of the heating unit 10, as shown. The air inlet 17 and air outlet 18 are, ideally, positioned in the housing 25 to provide a passageway 19 for ambient air to be passed through the heating unit 10, as indicated by the airflow direction arrows in Figure 1.
A power cable 24 which supplies electricity to the electric fan 11, preferably, enters the heating unit 10 on a side of the housing 25 towards the fluid inlet 15 to keep the visible cabling to a minimum and away from any risk of water contact at the fluid outlet, where any bleeding of the heat exchanger 12 to remove air bubbles, for example, would occur.
In use, the heating unit 10 is connected between a hot water inlet pipe 20 and a hot water return pipe 21 of a central heating system, or similar. The hot water inlet pipe 20 should be provided with a thermostatic control valve (TCV) 22, or similar means, to control the supply of externally heated water to the heat exchanger 12, and the hot water return pipe 21 may be provided with a bleed valve 23, to allow air bubbles to be removed from the central heating system.
The cut-out temperature of the LTC device 13 in the heating unit 10 is set to a temperature that is below the temperature of the heat exchanger 12 while externally heated water is being supplied to it when the TCV 22 is open. In other words, the LTC device 13 is configured to supply power to the electric fan 11 only when the temperature of the heat exchanger 12 is detected to be above the cut-out temperature. Thus, while the temperature of the heat exchanger 12 is above the cut-out temperature of the LTC device 13, the electric fan 11 draws ambient air across the heat exchanger 12, thereby forcing convection. The cut-out temperature is, preferably, below 40°C.
When the TCV 22 detects that the ambient air in the room, or enclosed space, in which the heating unit 10 is installed, is at, or above, a temperature corresponding to a selected setting of the TCV 22, it closes to restrict any further supply of externally heated water into the heat exchanger 12.
However, as the LIC device 13 is set to operate at a temperature that is lower than the temperature of the heat exchanger 12 while externally heated water is being supplied to it, the electric fan 11 continues to operate, passing ambient air over the heat exchanger 12, and thereby cooling it, until the temperature of the heat exchanger 12 reaches the cut-out temperature of the [IC device 13. At this point, the heat exchanger 12 will be sufficiently cool that it will not be able to heat ambient air by natural convection significantly to make a difference to the ambient air temperature in the room.
When the TCV 22 detects that the ambient air temperature in the room has fallen below a desired setting, it opens to allow externally heated water to be supplied to the heat exchanger 12. The heated water raises the temperature of the heat exchanger 12 to above the cut-out temperature of the LIC device 13 such that power is supplied to the electric fan 11, which draws ambient air across the heat exchanger 12 to heat the room.
It will of course be appreciated that the fluid inlet 15 and fluid outlet 16 may be positioned on the same side of the heating unit 10, and that the air inlet 17 and air outlet 18 may be arranged such that ambient air is drawn through the heating unit 10 and expelled from any side, whilst still providing a heating unit according to the present invention.
