Abstract

234,318. Woude, D. van der. June 3, 1924, [Convention date]. Heating buildings.-Relates to hot water heating-systems for buildings &c. of the kind such as is described in Specification 156,829, in which the admision of water to the radiators is controlled by adjustable valves or throttling devices, and the water is discharged by a return pipe 6 into an open tank 7, from which it is delivered by a pump 8 to the boiler or heater. In order to avoid constant manipulation or adjustment of the throttling devices as the supply pressure varies, the water, before entering the radiators 4, is conducted into one or more intermediate chambers 9 at a high level in which an approximately constant pressure is maintained. In the arrangement shown in Fig. 1, which is suitable for a system including a large number of radiators, several intermediate chambers 9 are provided, each of which is open to the atmosphere and the level of water therein controlled bv a float valve 10, while the supply of water to the radiators is controlled by valves 12 arranged in the outlet pipes from the radiators. Additional valves 13, 14, 15, 16 are provided for placing out of operation or draining individual radiators or the entire system. In a modification, Fig. 2, which is suitable for a single dwelling, the boiler 1 is replaced bv a heating coil 18 arranged in the single intermediate chamber 3. The heater may also be arranged between the chamber 9 and the radiators, and the chamber 9 may be in the form of a closed tanh in which a constant pressure above that of the atmosphere is maintained.
