HEATING SYSTEM

Temperature Delta Control for a Hydronic Heating/Cooling System.

A controller assembly controls water flow through individual emitters of a heating/cooling system based on a temperature setpoint and room temperature indicator obtained from an associated thermostat. The controller assembly provides delta temperature room control using a high precision movement actuator fitted with two pipe temperature sensors to power modulate individual radiators, underfloor heating circuits or fan-coils to provide energy efficiency for individual room heating/cooling control. Based on the temperature difference between the room temperature and the setpoint the controller assembly controls water flow through the emitter by adjusting a valve to attain a target temperature delta between the inlet and outlet of the emitter. As the room temperature approaches the setpoint so that the temperature difference decreases, the power output of the emitter is modulated to achieve desirable performance characteristics.

8556. Krell, O. April 8. Heating buildings.-To heat the water in a lowpressure hot-water heating-system to a temperature higher than 100‹ C. without the formation of steam, the water in the system is subjected to an additional external pressure of such an amount that the pressure at the highest water-level in the system is greater than the steam pressure corresponding to the highest temperature arising in the system. The Figure shows the usual boiler a, flow and return pipes b, c respectively, and radiators d. Between a water-supply cock f and the boiler a, is provided a pressure cylinder h, which also acts as an expansion vessel. The cylinder h is provided with a loaded piston i, k, to give the necessary increase of pressure to the water in the system. Instead of the cylinder and piston, the additional pressure may be provided for by means of a pump or column of water connected to any suitable place in the system, or the system may be connected to a hydraulic main. By throwing out of action the apparatus for producing the additional pressure, the system may be used as an ordinary open lowpressure hot-water circulating-system.

The expansion vessel (1) of a heating or cooling installation, divided by means of a flexible diaphragm (2) into two separate chambers (1a,1b) for a working fluid and a pressure fluid, is supported on a frame structure (B1) in which a compressor unit (3,6,7) is fitted. This serves for the preparation of a pressure fluid supply within a pressure fluid container (3), which is fed by a manostat-controlled (6) compressor (7) and is kept under a given operating pressure. The maintenance of a given pressure in the working fluid of the expansion vessel (1) is carried out by a differential pressure control of the pressure fluid, the associated chamber (1b) for which in the expansion vessel (1) is connected to the pressure fluid container (3) through a pressure fluid feed and drain duct (12) via an inlet or feed valve (8). A branch duct (12') connected to this pressure fluid duct (12) contains an outlet valve (9). Both valves (8,9) are controlled by a differential pressure manostat (5) which senses the pressure in the pressure fluid chamber (1b) via a separate measurement duct (11) and brings about the supply of pressure fluid into, or the discharge of pressure fluid from, the pressure fluid chamber (1b) when the values fall below, or exceed, a pressure fluctuation bandwidth.

Pressure management system

A pressure management device (10) for use with a heating system is disclosed which obviates the need for manual topping up of the heating system, protects against flooding and avoids danger of backflow of heating system fluid and consequent contamination of a mains water supply. The pressure management device has an inlet (12) for connection to a mains water supply; an outlet (14) for connection to a heating system; and a fluid flow path between the inlet and the outlet. A one-way valve (16) is disposed in the fluid flow path and arranged to permit flow in the direction from the inlet toward the outlet and to resist flow in the opposite direction. A pressure reducing valve (18) is also disposed in the fluid flow path and is configured to respond to an outlet pressure of the pressure management device, being normally maintained in a closed state by the outlet pressure but adapted to open when the outlet pressure falls below a threshold. In this way the pressure reducing valve causes the heating system to be topped up when necessary. Additionally a flood prevention device (20) is disposed in the fluid flow path and is configured to close in response to excessive flow through the pressure management device, so that any risk that the pressure reducing valve might permit uncontrolled release of water in the event of a leakage in the heating system is obviated.

Fill valve for a water heating system

A fill valve for a water heating system. An expansion tank is provided with a flexible diaphragm which divides the tank into a water chamber and a closed gas chamber. A fill valve assembly is mounted within an opening in the tank and includes a valve body having an axial passage and a radial passage connects the axial passage to a water inlet. One end of the axial passage communicates with the water chamber of the expansion tank, while the opposite end of the axial passage communicates with the water heating system. The central portion of the axial passage defines a valve seat and a hollow valve member is mounted for sliding movement in the axial passage, and the inner end of the valve member extends into the tank in position to be contacted by the diaphragm. Mounted on the valve member is an annular valve which is biased to engage the valve seat. A plurality of ports extends laterally of the valve member and provides communication between the inlet and the interior of the valve member. When the liquid in the water heating system expands, the diaphragm will be flexed inwardly causing the valve to be biased to a closed position to prevent water from entering through the inlet. When the volume of water in the heating system contracts, the diaphragm will flex outwardly moving the valve member within the valve body to open the valve and permit water to flow from the inlet to the heating system.

[Class 64 (ii).] In a hot-water heating system, an auxiliary introduction of heat is effected in the outflow conduit beyond the pump without steam formation occurring. The auxiliary heating may be effected directly or indirectly, and it may operate on the entire flow or on branched parts thereof. Cool water from the return flow may be introduced on the inlet side of the pump to reduce the risk of steam formation If a heating circuit of particularly high temperature be desired, the pressure in the circuit is increased beyond the pressure requisite for conveying the liquid.

Liquid heating system

ABSTRACT OF THE DISCLOSURE The power supply to a liquid heating system is ob-tained, according to the invention, substantially from a high pressure feed pump followed by a pressure reducing element, conversion of the mechanically supplied energy into heat taking place with no loss of pressure. The temperature in the heating system is controlled by varying the output from the high pressure feed pump, whereas the cross-section of the choke is the pressure reducing element is constant. According to the invention, additional heat sources of another kind may be used in the heating system.

MEANS FOR HYDRAULIC CONNECTION OF AN EXPANSION VESSEL AND EXPANSION VESSEL PROVIDED WITH SAID MEANS

Improved circulation system

A heating system (10) has an expansion tank (11) which provides water to a low pressure boiler (12) for heating. Heated water is distributed around a fluid conduit (13, 16) to one or more radiators (14) then returned to the boiler. A pump (17) is connected to the outlet conduit to assist fluid flow through the system when the system is active to provide heating. Pressure control means (18, 19, 21, 21A, 26) maintains the fluid in the distribution conduit at a positive pressure during periods when the system is quiescent and includes a non-return valve means (18) in the outlet conduit (13) and a further valve means (19; 26) to prevent fluid flowing through the return conduit (16) to the expansion tank when the system is quiescent and/or when the pressure of the fluid in the distribution conduit falls below a first predetermined threshold. A pressure responsive means (21; 21A) activates the pump (17) if the pressure in the distribution conduit falls below the first or a second predetermined threshold. The arrangement ensures that the system will operate even if one or more of the radiators (14) are disposed above the level of the fluid in the tank (11) without the need to pressurise the system and may be adapted for use with air conditioning or cooling systems.

Bei einer Druckausgleichsvorrichtung für Heizanlagen ist ein Ausgleichsbehälter vorgesehen, in dessen Innerem sich eine Blase (11) befindet. Überschußwasser kann aus der Anlage über Leitungen (15,16) in die Blase geführt werden. Bei Unterdruck kommt Wasser aus dem Ausgleichs­ behälter über Leitungen (15,17,18) in die Anlage. Es sind ein Überströmventil (2) und eine Pumpe (4) vorgesehen. Bei Überdruck in der Anlage öffnet sich das Überström­ ventil (2) und läßt Wasser in den Ausgleichsbehälter (14). Kommt es zu Unterdruck in der Anlage, schaltet ein Druck­ schalter (3) die Pumpe (4) ein, die Wasser aus dem Aus­ gleichsbehälter in die Anlage pumpt. Gleichzeitig wird in der Elektronik-Steuereinrichtung (5) ein Zeitimpuls ausgelöst und bewirkt, daß die Pumpe (4) nicht mehr druckabhängig, sondern zeitabhängig abgeschaltet wird. With a pressure compensation device for heating systems an expansion tank is provided, inside it there is a bubble (11). Excess water can come out the system via lines (15, 16) into the bladder will. At negative pressure, water comes out of the compensation container into the system via lines (15, 17, 18). There are an overflow valve (2) and a pump (4) are provided. If there is overpressure in the system, the overflow opens valve (2) and lets water into the expansion tank (14). If there is negative pressure in the system, a pressure switches switch (3) on the pump (4), the water from the off pumps the surge tank into the system. At the same time in the electronics control device (5) a time pulse triggered and causes the pump (4) no longer depending on pressure, but is switched off depending on time.

Elastic membrane lining for water heater - reduces atmospheric corrosion of metal outer cylinder

In a heating installation fired by solid fuel, the metal outer cylinder of the heater is lined with a flexible, elastic material to keep the heated water and its vapour inside the lining and separate it from the region between the lining and the outer cylinder-which is open to the air. Without the lining, air in the upper part of the cylinder-which may, at times, be only part full of water - being air saturated with water vapour, would soon corrode the metal. With the lining, the metal encounters air of no more than ordinary humidity.
