Abstract
A forced air hot water furnace including means for initially heating water and delivering the heated water to a radiator, the radiator having a fluid conduit as a part thereof, the fluid conduit having an upstream section with an orifice or passage of predetermined cross-sectional flow area, and a downstream section with an orifice or passage of reduced or smaller cross-sectional flow area whereby the water, as it passes through the conduit of the radiator, is increased in its velocity whereby to provide increased energy transfer within the radiator means, the conduit of the radiator being provided with heat transfer fins in surrounding relationship thereto.
Claims1
A forced air hot water furnace comprising:
- a reservoir provided with a supply of fluid, said reservoir having an inlet port for ingress of said fluid and an outlet port for egress of said fluid;
- pump means provided with inlet and outlet ports, the inlet port of the pump being in communication with the outlet port of the reservoir;
- coiled tubing having a series of interconnected, U-shaped stretches, said stretches lying in multiple, nonparallel planes, the coiled tubing having a fluid inlet and a fluid outlet, the outlet port of the pump being in communication with the fluid inlet of the coiled tubing;
- means for heating the fluid in the coiled tubing;
- at least one radiator provided for transfer of heat in a fluid conduit to surrounding air, said said fluid conduit having an upstream section with an orifice of predetermined cross-sectional area and a downstream section with an orifice of smaller cross-sectional flow area;
- fluid coupling means between the outlet of the coiled tubing and the upstream section of the fluid conduit of the radiator;
- and
- a blower for forcing air toward said radiator means so as to pass the upstream radiator section first.
