A further object of the present invention is to provide a heated satellite unit or interface unit that can be remotely controlled by a specific command required by the user to have surrounding heating characteristics.

These and other objects may be realized by means of a heated satellite unit or interface unit according to the following claims.

For a better understanding of the present design, the accompanying drawings are provided in a non-limiting sense:
1 shows a piping shape of a first embodiment of a satellite unit according to the present invention;
2 shows a piping shape of a second embodiment of a satellite unit according to the present invention;
3 is a piping configuration of a third embodiment of a satellite unit according to the present invention;

Referring particularly to Figure 1 of the drawings, Figure 1 shows a heated satellite unit or interface unit 1, which is schematically illustrated for internal piping components. The satellite unit 1 is connected to the space heater 2 and the tap 3 for domestic hot water in the environment through the delivery pipes 4 and 5 and the recovery pipes 6 and 7 . A transfer pipe 8 for remotely generated hot water (in a manner already known) is connected to the satellite unit 1 and a pipe (not shown) for withdrawing water at a temperature lower than the inlet temperature for the remote location 9, and the fluid will be heated again and exhausted from the satellite unit 1. These pipes 8 and 9 are connected to the inlet pipe 10 and the outlet pipe 11 of the satellite unit 1.

The satellite unit 1 is connected to the delivery pipe 8 and the recovery pipe 9 in a manner known per se.

More specifically, the satellite unit 1 includes a heat exchanger 12 and a sensor 13 for the temperature of the hot water flow arranged in the pipe 4 inside. Optionally, a safety thermostat 14 may be provided which is directed towards the space heater 2 and within which the temperature of the hot water can be detected. The pipe 6 in which the pump 18 is located comes out of the space heater 2 and the pipe passes through the heat exchanger 12 before exiting from the satellite unit 1, A valve 19 is provided for regulating the flow downstream of the heat exchanger, together with a temperature sensor 27 (located within the heat exchanger 11).

The safety thermostat 14 is connected to the valve 19 and the temperature sensor 27. Thus, after the thermostat has been used to heat the above-mentioned surroundings, it can interrupt the recovery of the fluid at any time whenever it is necessary to shut off the recovery of the fluid for any safety reasons. All this fact is already known.

At the same time the pipe 5 diverges from the pipe or pipe 4 before the pipe 4 is introduced into the heat exchanger 12 and the pipe 5 passes through the heat exchanger 12 before reaching the tap 3. [ (20). A temperature sensor (21) for hot water is connected to the pipe (5).

As mentioned above, the pipe 7 from which the flow controller or flow meter 22 is provided leads from the tab 3. The pipe 7 passes through the heat exchanger 20 and downstream there is provided a valve 25 for regulating the flow of water and is located in the pipe 11 downstream of the heat exchanger towards the pipe 9.

The satellite unit or interface unit 1 comprises an electronic controller or control unit using an electronic controller or control unit, preferably a microprocessor, which is connected to the various electrical components of the satellite unit or interface unit 1 do. In particular, the control unit 30 includes a temperature sensor 13, a pressure sensor 15 in the pipe 4 downstream of the sensor 13, a temperature sensor 21 for hot water circulated in the pipe 5, Is connected to a valve (19) located in the tube (11) and a valve (25) for regulating fluid flow downstream from the heat exchanger (20).

The control unit 30 controls both the space heating function for the surroundings and the function for generating the domestic hot water immediately. This is implemented through input signals received from components connected to the control unit.

In addition to the above-mentioned components, the microprocessor unit 30 is connected to a universal thermostat 37 which can control the temperature of the surroundings where it is to be heated, and the thermostat is connected to a satellite unit or a device Or may be arranged outside the device.

The control unit 30 is operated on the control valves 19 and 25 to regulate the main flow supplied to the interface unit or the satellite unit. The flow control may be provided separately via the valve 25 and the valve 19. As an alternative, the flow fed to the interface unit or satellite unit 1 may be controlled by controlling a single valve located at the inlet side of such a unit, (20) to regulate the flow to the entire interface unit. Although the valves are not shown in the drawings, the features and methods of use of the two valves in the interface unit are well known in the art.

When the indoor thermostat 37 has to be heated, the control unit 30 arranged in the interface unit 1 switches on the pump 18 and requests from the thermostat 37 Partially open the control valve 19 to achieve the desired temperature for the fluid, as measured by the sensor 13, so as to meet the desired temperature. After operating the above-mentioned components 18 and 19, the control unit 30 adjusts the pressure detected by the pressure sensor 15 and the temperature status detected by the thermostat 37 . When a problem is detected in one of these components, the pump 18 is switched off and the control valve 19 is closed.

Similarly, when there is a demand for hot water from the user in the vicinity of where the satellite unit 1 is located, i.e. when the flow meter or flow switch 22 detects the flow of water (by opening the hot water tap) The control unit 30 of the control valve 25 partially opens the control valve 25 to realize the desired water temperature measured by the temperature sensor 21. [

Now, consider FIG. In Fig. 2, parts corresponding to the parts described in claim 1 are denoted using the same reference numerals.

In the configuration schematically shown in Fig. 2, the space heating to the periphery can be carried out arbitrarily between the piping 4 of the satellite unit or interface unit 1 and the heating circuit or hot water inlet piping 8, Of heat exchanger. There is therefore a direct fluid connection between the heating system and the distribution network for hot water generated remotely from the surroundings via the satellite unit or interface unit 1.

2, when the thermostat 37 switches on the space heater 2, the control unit 30 arranged in the satellite unit or interface unit 1 switches the pump 18 on . It is then actuated on the mixing valve 40 provided in the recovery piping 6 downstream from the pump 18 (see fluid flow direction in the pipe or pipe 6). This is carried out to realize the desired temperature for the flow measured by the temperature sensor 13.

When these components are activated, the control unit 30 monitors the status of the safety thermostat 14. When the thermostat detects a problem, the pump 18 is switched off and the mixing valve 40 is closed. When the safety thermostat 14 detects the problem (typically the water temperature is above a predetermined reference point), an additional safety valve is provided to stop the flow of water from the remote source to the space heater It is possible.

Similarly, when there is a demand for hot water from the user in the vicinity of the satellite unit 1, that is, when the flow meter or flow switch 22 detects the flow of water (by opening the hot water tap) The control unit 30 partly opens the regulating valve 25 to implement the desired temperature of the flow measured by the temperature sensor 21. [

Fig. 3 shows a third modification of the present invention. In Fig. 3, parts corresponding to the parts already described above are indicated using the same reference numerals.

In this configuration, the space heating is provided without any heat exchanger between the heating circuit or the space heater 2 and the hot water pipe 8 entering the interface unit 1, starting from the surroundings, starting from the heating system and the remote source, There is a direct fluid connection between the systems.

In this case, if the surrounding thermostat 37 requires heat, it may be possible to open the valve to a given point determined by the algorithm provided to the control unit 30, The controller or control unit 30 is operated on the control valve 19. [ This algorithm corresponds to the amount of hot water that has to be provided to the heating plant in order to be able to implement a particular set temperature. The correlation between the temperature and the flow of water is tabulated in the memory (not shown) of the control unit 30.

Similarly, when there is a demand for hot water from the user in the vicinity of where the satellite unit 1 is located, i.e. when the flow meter or flow switch 22 detects the flow of water (by opening the hot water tap 3) The unit 30 partially opens the regulating valve 25 to implement the desired temperature of the flow measured by the temperature sensor 21.

1 and 2, when a specific control function is implemented, the control unit 30 determines, based on the temperature detected by the temperature sensor 27 located in the recovery pipe 6, Calculate the temperature that the circulating flow within the domestic hot water circuit and heating circuit must reach.

In the configuration shown in Figure 3 the control unit 30 is controlled by the temperature detected by the temperature sensor 27 located in the tube 6 when the heated interface unit is provided for ambient space heating, The position of the valve 19 is calculated. When the interface unit is operated to provide domestic hot water, the control unit 30 calculates the final temperature for domestic hot water according to the temperature detected by the temperature sensor 27 located in the recovery pipe 6 .

In all of these configurations, maximum opening can be set for each valve. In addition, for all configurations, if the regulating function is activated, the heated interface unit or satellite unit 1 will be able to react quickly after a certain waiting period or stand-by time, Temperature maintenance is provided to maintain heat exchanger 20 to generate domestic hot water at a temperature compatible with the response time. The cycle for maintaining the temperature is started when the control unit 30 partially opens the control valve 25 and when the temperature sensed by the temperature sensor 21 falls below a given threshold do. The temperature maintenance cycle is stopped when the temperature detected by the temperature sensor 27 reaches or exceeds a given predetermined value.

The temperature maintenance function may operate 24 hours a day, may be shut down, or may only operate for a predetermined time during a day.

The control unit (30) of the satellite unit may be provided with an auxiliary contact so that the control unit can be programmed.

The heated interface unit or satellite unit 1 may be provided with a control unit which can be attached to an external device via a cable or a radio connection. Through this connection, the interface unit or the satellite unit can be set and adjusted at a distance so that at least all of these settings, which can be performed by operating directly using the interface, can be performed remotely.

Finally, by a specific command transmitted from the user to the control unit of the interface unit or the satellite unit 1, the behavior of the interface unit can be changed, and one of the components connected to the interface unit The input signal received from the element to the interface unit can be canceled.

The present invention therefore relates to an interface unit or satellite unit provided with a pre-programmed and adjustable control unit which can be operated to change the temperature of the water flow in the surrounding domestic hot water circuit and in the normal space heating circuit. This is to limit the temperature of the fluid or water entering the interface unit or satellite unit and to limit the temperature of the water coming out of the satellite unit to recover the water to the remote station where it is heated again.

This design allows the control unit to identify the over-limit temperature at which the control unit is operated for safety. Throughout this design, it is possible to provide a temperature maintenance function for water for use in households that allows the temperature to be maintained at a predetermined value.
