HoT WATER HEATING sYsTEM WITH PLURAL RIsER CONTROL J.E. ERcNBRAK Er AL Patented Oct. 24, 1933 PATENT oFllcE 1,932,069 nor WATER HEATING SYSTEM WITH "Mm PLURAL RISERCONTROL John Edward Erca'nbrack and Forrest A. Johnson, Chicago, Ill.; said Johnson assignor to Bell & Gossett Company, Chicago, I ll., a corporation o! Illinois Application April 28, 1930. Serial No. 447,996 Claims. (Cl. 237-56) Our present invention relates to the provision of ahot Water heating system with plural riser control for heating and distributing hot Water for house heating purposes and also for service 5 supply purposes.
TheV eiiiciency of oil, gas, and other mechanically operated and controlled burners in connection with house heating systems has now become pretty broadly recognized. Several plans have also been developed and disclosed for combining with a hbt Water house heating system provided with a mechanical burner means for heating Water for a domestic or service supply for the same premises. These plans, pretty generally, involve the provision of an auxiliary casirg through which the boiler Water freely circulates and in which is disposed acoil included in the hot water domestic or service supply system.
In such combined systems it is generally proposed to connect the auxiliary casing with a return from the house heating system and to control the admission of hot water from the Aboiler to the house heatingsystem by a thermostatically operated valve. A house heating system generally involves a plurality of risers from the boiler to the radiators and a like plurality of returns from the radiators to theboiler. The thermostatically operated valve is disposed n the circulating system between the' boiler and the place where the risers separate, so that when the valve opens the hot water flows from the boiler to as many risers as may be present in the house heating system. It is a characteristic of such combined syste to maintain the boiler water at ya relatively high temperature requisite for heating the domestic or service water supply, and the presence of this relatively high temperature boiler water renders the house heating system considerably quicker and more effective in action when the thermostatically operated valve opens for permitting the boiler water to flow into the house heating system andthe radiators.
However, in such systems, when the weather 45 is mild, the temperature of the water inthe r'dators falls below the temperature 'of the water returning from the auxiliary casing toy the boiler, in whichV event a. reverse circulation not infrequently develops in the house heating system commencing with the return to which the auxiliarycasing is connected ilowing up through the radiator or radiators to ,which that return Y is connected through the branched risers to the f several radiators and back through another re- 66 turn or returns, which are generally present in the system, to the boiler. This reverse circulation heats the house unduly in mild weather and when once established blocks and delays a ncrmal circulation when the thermostat calls for hot water in the house heating system. 30
systems employing mechanically red heaters for supplying heated water for service and domestic uses. 70
We have attained the foregoing objects and results by means of the structure illustrated in the accompanying drawing,v in which- Fig. l isa schematic illustration of such combined hot vwater house heating and service supply heating systems embodying our invention;
Fig. 2 is a fragmental, central, vertical section through our improved valve construction; and
Fig. 3 is a section on line 3-3 of Fig. 2.
Similar reference charactersrefer to similar parts throughout the respective views.
The hot water house heating systems to which our invention is applicable comprise a boiler 5 heated by an oil burner 6, or some other form of mechanically operated burner, which is elec trically controlled by an aquastat 'I for maintaining the boiler water at a predetermined temperatu-re. From such a boiler comes a riser 8, which is usually branched to lead to different portions of the premises to be heated.
We provide the riser 8 with a T 9 which connects by means of a pipe 10 with the top of an auxiliary casing 11, the bottom of which connects through a pipe 12,'elbow 13 and reducing T 95 14 with one of the usual returns 15 to the boiler.
Within the casing 11 is a coil a having independent connections exterior of the casing with piping b owing to, and piping creturning from, a hot water storage tank d. The tank d is provided with an outlet e connected with the piping l d A for supplying thel premises with hot waterI and with an inlet f connected with the water service supply of the premises.
At or above the level of the connection of the pipe 10 with the auxiliary casing 11 thecasing 11 is provided with a plurality of inwardly extending. radially disposed stub tubes 18, the inner e'xids whereoi constitute faces of a common conical development adapted to be closed and 110 opened simultaneously by a single conical valve 17. The outer ends of the respective stub tubes 16 are connected with risers 18 and 19 leading respectively to radiators 20 and 21. The radiator 20 connects with return 22 connecting with the reducing T 14 and, radiator 21 connects with return 23 reaching the boiler independently.
The valve 1'7 is provided with a stem 24 which extends upwardly from the valve through suitable packing appliances 25 in the cover 26 of the auxiliary casing 11. Upon the cover 26 is mounted a motor 27 and associated equipment for opening and closing the Valve 17 through the stem, 24, the operation of which motor is controlled through a thermostat 28 located in the premises to be heated.
It will now be seen that with our combined systems of hot water house heating and service water heating it will be impossible, no matter how cold the water in the radiators may get, for a counter-circulation to arise through return 22, radiator 20, riser 18, riser 19, radiator 21 and back to the boiler through return 23, as risers 18 and 19 are simultaneously and positively closed when they are not supplying radiators 20 and 21 with hot water.
AHaving described our invention what We claim as new and desire to secure by Letters Patent is:
1. In a hot water heating system, a boiler, a plurality of risers and a plurality of returns having connection with said boiler, heat transfer elements included and establishing communication between said risers and returns, and means for simultaneously opening and closing said respective risers with respect to said boiler and with respect to each other.
2. A hot water heating system including a boiler, a feed from said boiler, a plurality of returns to said boiler, an auxiliary casing connected with the feed from said boiler and one of the returns thereto, a plurality of radially disposed inwardly extending stub tubes associated with said auxiliary casing, and a single valve co-operating with the inner ends of said respective tubes whereby they may be closed from communication with said casing and with each other, risers connected with said stub tubes and heat transfer elements connecting and establishing communication between said risers and returns.
3. A hot water heating system comprising a5 boiler, a plurality of risers from and Yreturns to said boiler, heat transfer elements' cnnectingf and establishing a circulation between said risers and returns, and means for simultaneously closing said respective risers with respect to said boiler and with respect to each other.
4. In combination a boiler, an auxiliary casing connected to the top and to the bottom of said boiler, said casing having a plurality of discharge ports therein, risers connected with said discharge ports, radiators connected with said risers, returns from said radiators to said boiler, and means for simultaneously opening or closing said discharge ports with respect to said boiler and with respect to each other.
5. in a hot water heating system, a boiler, a plurality of risers from and returns to said boiler, heat transfer elements connected and establishing a circulation between said risers and returns, said risers and returns constituting a plurality of complete circulating circuits, and a 4single means for controlling said respectivev circulating circuit with respect to each other and with respect to said boiler.
