Patented Apr? 1949 UNITED STATES OFFICE Application January 3, 1946, Serial No. 638,876 In France January 5, 1945 3 Claims.
This invention relates to a heating or cooling plant constituted by radiating panels containing two heat exchange coils placed one above the other and in series, the beginning of the lower coil and the point common to both coils of each panel being connected through a three-way valve, or its equivalent, to the discharge Point of a water temperature regulating device such as a boiler (or the refrigerator, according to the case), the entrance of the said boiler or refrigerator being connected through a pump to an accumulator for the cooled (or heated) water which is fed by the discharge of the upper coils of all panels, provision being made for a by-pass conduit allowing to put the boiler, or the refrigerator, out of the circuit feeding the aforesaid threeway valve, the said conduit being controlled by a thermostatic control which acts also on the said valve, in such manner that, in the case of a high (or low) temperature peak, the supply of hot (or cold) water to the entrance of the first coil is closed, the point common to both coils being supplied with cooled (or warmed) water coming from the said accumulator, and inversely in case of a low (or high) temperature peak.
This heating or cooling plant comprising radiating panels has less inertia than the known systems, since the radiating panels respond rapidly to the thermostatic regulating device, so that the differences of the temperature with respect to the prescribed value are of short duration, the comfort is increased, as well as the efliciency of the plant, in such manner that the expense of fuel is not higher than in ordinary installations comprising radiators, with respect to which the advantage of greater comfort is wholly obtained.
The annexed drawing shows by way of example an embodiment of the heating plant according to this invention, this plant being also adapted for operation, inversely, as a refrigerating plant.
Fig. 1 represents schematically, in perspective, a radiating panel which is shown separately.
Fig. 2 is a schematical elevational view of the entire plant.
Fig. 3 is a vertical partial section of a radiating panel.
As shown on the drawing, the radiating panels P employed in the plant contain two tubular coils I and 2, the second being placed above the first, that is to say nearer to the emitting surface Fe. 3 is the entrance of the lower coil, 4 is the point common to both coils and constituting the entrance of the second one, and 5 is the discharge end of the latter.
The points 3 and 4 of all panels are connected to two main conduits 6 and 1 leading to two entrances of a three-way valve 8 the third entrance of which is connected by a pipe In to the boiler 9 of the plant. All discharge points 5 are connected to a pipe H which leads to a cooled water accumulator l2, which is in its turn connected to the boiler 9 by a pipe l3, a pump l4 being interposed. Between the pipe l0 and a point of the pipe 1"3 between the pump and the boiler is connected a Icy-pass conduit [5. A motor-controlled valve I6 is mounted at the junction of conduit l5 and pipe it), this valve being actuated by a device controlled by a thermostat H, which controls at the same time the valve 8.
The plant operates as follows: When the temperature in the rooms to be heated tends to increase above the prescribed temperature, the thermostat ll, which is placed in a test room, acts upon the motor-controlled valve I6 which puts out of circuit the generator 9 and opens the circulation through the by-pass I5. At the same moment, the valve 8 is put into such a position that the coil 2 is fed with cooled water, while the normal feeding of the coil 1 is arrested. The fluid flowing through the arrangement is then at a low temperature, i, e. at the temperature of the returning fluid, and exerts a refrigerating action until the balance is restored in the heated rooms.
It is to be noted that the cooling action is brought about only by the upper coil 2 which is very near to the emitting surface, so that the bulk of materials to be cooled is reduced to the upper layers of the panels and does not extend through the entire mass of the same, procuring thus a quick and efficient cooling action.
When the temperature in the rooms tends to descend below the allowed limit, the thermostat, acting inversely, reestablishes the normal heating cycle.
The device as described may of course be used, by an inverse operation, to the cooling of rooms or other spaces during the hot season, the boiler being replaced by a cold generator and the accumulator receiving the water which has been warmed by its cooling action.
