Abstract
A heat interface unit comprises a primary heat input 11 servicing a domestic hot water (DHW) side 13 and a central heating (CH) side 12 from the primary heat input based on a position of a three-way mixing valve 14 with a V-configuration valve member 15, e.g. a Belimo valve. The mixing valve is ideally a changeover ball valve having a ball valve member whose position is controlled by a stepper motor.
Description
A HEAT INTERFACE UNIT
Technical Field of the Invention
The present invention relates generally to the field of domestic boilers/heaters and particularly to a Heat Interface Unit utilising a standard 3-way mixing valve with a "v" outlet to linearise the flow control.
Background to the Invention
A Heat Interface Unit 011(J) is a domestic boiler without the primary heat exchanger and burner, this is replaced by heat delivered from a central source via its primary circuit. The unit manages the extraction of the heat energy from the primary circuit and its subsequent delivered to the relevant hot water or central heat systems.
Conventional Hill's use multiple linear actuated electronic control valve systems and electronic sensors to control individual circuit flows.
It would therefore be an advance in the art to provide a Hill allowing the right (DHW) and Left (CH) ports to be controlled accurately and independently to the other outlet valve port Existing design solutions currently on the market do not satisfy the above requirements and the new design below solves all of the current issues.
Summary of the Invention
According to one aspect of the invention, there is provided a heat interface unit comprising a primary heat input servicing a domestic hot water (DHW) side and a central heating (CH) side from the primary heat input based on a position of a main control valve wherein the main control valve is a 3-way mixing valve with a V-configuration valve member.
Providing a heat interface unit with this configuration will allow the flow to the right (DHW) and Left (CH) ports to be control accurately and independently to the other outlet valve ports. In the off position, the main control valve will isolate the CH and DHW ports from the primary heat input. This method allows one control valve to offer fluid control to both CH and DHW circuits which in turn, offers increased circuit.
connectivity and therefore an increased operational capability over the current flow management system available in this type of appliance in the current market.
The main control valve is preferably a standard 3 way mixing valve with a valve member having "v" outlets to linearise the flow control. Such a valve is manufactured by Belimo This particular valve is a 3-way, changeover ball valve. The Belimo valve is operable through rotation 90" clockwise and 90' anticlockwise.
According to the present invention, the position of the ball valve member in the valve body is driven by a rotary actuator so it can be driven to the desired positions. The desired positions are 90' clockwise, 90' anticlockwise and 180' anticlockwise.
A stepper motor is preferably used to adjust the position of the ball valve member in the valve body between these three positions. The motor may drive the ball valve in a single direction only or in both the clockwise and anticlockwise directions.
In the off position, the main valve will preferably isolate the Left (CH) and Right (DHW) pork from the primary flow.
It is intended to operate the valve using a rotary actuator rotating 270°, controlled by circuit sensors.
Detailed Description of the Invention
In order that the invention may be more clearly understood one or more embodiments thereof will now be described, by way of example only, with reference to 20 the accompanying drawings, of which: Figure 1 is a schematic view of a heat interface unit servicing a domestic hot water (DHW) side and a central heating (CH) side from a central heat source based on the position of the main control valve.
Figure 2A is a schematic view of a main control valve in a closed condition.
Figure 2B is a schematic view of a main control valve in a90° clockwise condition.
Figure 2C is a schematic view of a main control valve in a 900 anticlockwise condition.
Figure 2D is a schematic view of a main control valve in a 1800 anticlockwise condition.
A schematic view of a heat interface unit 10 servicing a domestic hot water (DHW) side 13 and a central heating (CH) side I 2 from a central heat source I I based on the position of the main control valve 14, is illustrated in Figure 1.
The main control valve 14 is a standard 3-way mixing valve manufactured by Bell mo, with a valve member having -v" outlets or conduits. Both are designated as 'outlets' even though in practice, depending on the position of the valve member, one of the conduits will be an inlet to allow the central heat source 11 to feed either the domestic hot water (DHW) side 13 and a central heating (CH) side 12.
The Belimo valve is operable through rotation 90' clockwise and 90' anticlockwise. According to the present invention, the position of the ball valve member 15 in the valve body is driven by a rotary actuator (not shown) so the valve member 15 can be driven to the desired positions illustrated in Figures 2A to 2C. The desired positions are 'off' shown in Figure 2A, 90° clockwise shown in Figure 2B which allows the central heat source 11 to feed the domestic hot water (DHW) side 13, 90° anticlockwise which s second 'off' position and 180' anticlockwise which allows the central heat source 11 to feed the central heating (CH) side 12.
A stepper motor is preferably used to adjust the position of the ball valve member 15 in the valve body between these three positions. The motor may drive the ball valve member 15 in a single direction only or in both the clockwise and anticlockwise directions.
In the off position, the main valve will preferably isolate the Left (CH) and Right 25 (DHW) ports from the primary flow.
It is intended to operate the valve using a rotary actuator rotating 270°, controlled by circuit sensors.
The one or more embodiments are described above by way of example only. Many variations are possible without departing from the scope of protection afforded by the appended claims.
