Definitions
- This invention relates to a condition controlling system and more particularly to a system for controlling the temperature or humidity of air in a room or rooms .
- Room temperature is usually controlled by a thermostat mounted in a fixed position and wired to a stationary heating appliance. In this arrangement, the position of the thermostat cannot be changed readily if it is found that the thermostat does not exercise satisfactory control over the .temperature of the room, apartment or home concerned.
- Portable electric heaters are controlled by a thermostat switch provided on the heater itself, but this has the limitation that the heat output of the appliance is not determined by the air temperature of the room itself.
- condition controlling system which overcomes these problems, and which may comprise a temperature control system for portable or fixed heating appliances, or a humidity control system for a humidifier.
- an atmospheric condition controlling system comprising an atmospheric condition monitoring device provided with a transmitter arranged to radiate a signal representing the condition being monitored, and a receiver arranged to pick up the signals radiated " by the transmitter and provide an electrical output representing the monitored condition, for controlling an appliance which serves to determine said condition.
- the signal is preferably radiated by the transmitter only when the condition being monitored departs from a preset.level by more than a predetermined amount (above or below the preset level); the signal is preferably radiated at spaced intervals, which continue until the condition being monitored differs from the preset level by less than a predetermined amount.
- the system according to the invention may be such that the transmitter is arranged to control a plurality of the appliances for determining the monitored atmospheric condition; in a large space there may be a plurality of such transmitters at spaced locations .
- the transmitter may be a transmitter of any convenient electromagnetic radiation e.g. infra-red or radio waves, or of ultra-sound.
- the transmitted or radiated signal is coded and the receiver arranged to respond to signals bearing a predetermined coding.
- the condition controlling system may comprise a temperature controlling system, including a thermostat unit which incorporates the transmitter, in which case the electrical output of the receiver is used to control a heating appliance.
- the receiver output may be connected to a power switch for supplying or interrupting power to an electrical element of the heating appliance, according to whether the thermostat signals that the room temperature is below or above a preset level (which preset level may be permanently fixed, or, alternatively, selectively adjustable by an occupant) .
- the receiver and power switch may be incorporated in the heating appliance itself, or instead may be incorporated in an adaptor unit arranged to be plugged into a mains power socket so as to control any appliance plugged into itself.
- the system according to the invention may be provided with proportional power control, so that the power input to the appliance is greater the further the temperature, for example, is from the preset level.
- the system according to the invention may be arranged to control various types of heating appliance.
- the electrical output of the receiver may be used to control a valve in the supply pipe to a hot water radiator, or to control a motorised drive for air outlet vents of storage heaters or of air conditioning systems, or to control heating and cooling units of air conditioning systems.
- a condition controlling system may comprise a humidity controlling system, including a humidity monitoring unit incorporating the transmitter, in which case the electrical output of the receiver is used to control a humidifier.
- the air humidity can be kept substantially at a level preset on the humidity monitoring unit.
- Figure 1 is a diagrammatic elevation showing an electric heater, a thermostat unit and an adaptor unit in a room;
- FIGS. 2a and 2b are front and side views of the thermostat unit
- FIG 3 is a front elevation of a hot water radiator in a central heating system, having a water valve controlled by a thermostat system according to the invention
- Figure 4 is a side elevation of an electrical storage heater having displaceable air outlet vents controlled by a thermostat system in accordance with this invention
- FIG. 5 is a diagrammatic view of an air conditioning system controlled by a thermostat system in accordance with the invention.
- Figure 6 is a diagrammatic view of a humidifier controlled by a humidity controlling system in accordance with the present invention.
- a portable electric room heater 10 of convector type having an electrical heating element 10a.
- a lead 12 is fitted with a plug 14 to be engaged with an adaptor unit 20 which in turn is to be engaged with a power socket 30 of the room.
- the adaptor unit 20 houses a power switch which Is controlled by the electrical output of a receiver: a thermostat unit 40 responds to the room temperature to transmit coded infra-red signals, which are decoded by the receiver of the adaptor unit.
- the transmitter of the thermostat unit 40 is a multi-pulse infra-red transmitter (although other forms of electromagnetic radiation and ultrasonics may be envisaged), coded so as not to interfere with TV controllers and similar equipment.
- the receiver of the adaptor unit 20 includes a multi-pulse decoder circuit, controlling the power switch only in response to the signals having the unique coding of the transmitter.
- the thermostat unit which is shown comprises a thin rectangular housing with a leg 42 hinged to its back so that the unit may be stood on any convenient surface. Alternatively, or additionally, the unit may have a bracket or adhesive pads, or other means for wall mounting.
- a transmitter bubble 44 is positioned on the top of the unit, and a temperature control dial 46 is provided on its front together with a reset button 48.
- the usual temperature control 11 on the heater 10 is set to a maximum, so that the thermostat units 40 will exercise full control over the electrical power supplied to the heating element 10a.
- the reset button 48 on the thermostat unit is actuated to cause an initial signal to be transmitted, serving to close the power switch in the adaptor unit 20 and thus connect power to the heater 10.
- the transmitter sends a signal to open the power switch, whilst subsequently when the thermostat senses a slightly lower room temperature, then the transmitter sends a signal for closing the power switch again.
- the receiver and power switch may be incorporated in the heater 10, as indicated at 20a in Figure 1.
- the heater 10 may be arranged for fixed installation in the room concerned.
- the thermostat system may be used for controlling various types of heating appliances.
- a solenoid valve 50 in a feed pipe to a hot water radiator 52 in a central heating system is provided with a control unit 54 comprising the receiver, the electrical output of which is used to energise/de-energise the solenoid for opening/closing the valve.
- air outlet louvres 60 of a storage heater 62 may be opened or closed by a motorised drive unit 64 provided with a control unit 66 incorporating the receiver, the output of which controls the motorised drive unit 64.
- the thermostat system may be used for controlling an air conditioning system 70 as shown in Figure 5.
- the air conditioning system includes an air inlet 72, air outlet 74, air heating unit 76 and air cooling unit 78.
- the heating and cooling units 76, 78 are provided with respective control units 77, 79 responsive to electrical outputs from the receiver R of the thermostat system. Under cold ambient conditions, the heating unit 76 will be controlled so as to keep the room warmed substantially to the temperature set on the thermostat 40. Under warm ambient conditions, the cooling unit 78 will be controlled so as to keep the room cooled substantially to the temperature set on the thermostat 40.
- the condition controlling system may serve to control air humidity rather than air temperature.
- Figure 6 shows a humidity monitoring unit 80 preferably having a control dial 82 for setting the desired level of air humidity, and incorporating the transmitter.
- a humidifier 84 includes a control unit 86 and the receiver R.
- the transmitter sends a signal which is received and de-coded by the receiver R to provide its electrical output to control the humidifier for providing an increased level of humidity in the air which it delivers through its outlet 87.
- the transmitter sends a signal which is decoded by the receiver R for controlling the humidifier for providing a lower level of humidity in the air which it delivers.
- the humidifier may form the humidifier of an air conditioning system.
- the control system may include both thermostat and humidity controlling arrangements as described above.
- the systems which have been described provide portable thermostat or humidity controllers which may be moved about the room until it is found these exercise satisfactory control over the air temperature and humidity level in the room.
