US Patent:

48443352, Jul 4, 1989

Filed:

Mar 10, 1982

Appl. No.:

6/356627

Inventors:

Milton A. McKinley - Palisades Park NJ
Charles C. Castelli - Palisades Park NJ

Assignee:

Surgeonics Limited - Hudson Falls NY

International Classification:

F24D 300

US Classification:

237 8R

Abstract:

A control system for a hydronic heating system for an enclosed structure which includes a boiler and at least one heating zone controlled by a thermostat and having a circulator or zone valve for controlling delivery of heat from the boiler to the heating zone(s). The control system senses the ambient temperature external to the enclosed structure, and also the water temperature of the boiler. Responsive to those two sensed values, it determines an upper temperature for the boiler at which the boiler is shut off. The control system further periodically redetermines the upper temperature for the boiler in accordance with the heating demands of the enclosed structure, and accordingly is heuristic in nature. In the preferred embodiment, a central processing unit forms the heart of the control system, and digitally stores in memory words representative of the sensed temperatures and other pertinent parameters relating to timing. The central processor is programmed to perform the function of periodically redetermining the upper temperature for the boiler in accordance with the immediate past heating demands of the heated structure, and also controls the circulators, in first and second heat dumping modes, to dump heat from the boiler after a thermostat is satisfied.

Abstract:

Apparatus for use in a heating system wherein an enclosed region is heated by hot water flowing through a heat exchanger disposed in the region, the hot water being supplied from a boiler heated by a furnace which is electrically actuated and deactuated, the water being circulated between the boiler and the heat exchanger by a circulator pump which is electrically actuated and deactuated, a thermostat being disposed in the space to control the temperature therein and including an electrical switch which is closed when additional heat must be supplied to the region and which is otherwise open. The apparatus employs a first arrangement for actuating said furnace and said pump when said switch is closed and for deactuating the furnace and the pump when the switch is open, a timer which is automatically reset, said timer when electrically actuated operating for a preselected time period and then is automatically deactuated, a second arrangement for actuating said pump and said timer when said first arrangement deactuates said furnace and pump, whereby said pump continues to circulate said water when said switch is open and said furnace is deactuated while said timer remains actuated, and a third arrangement for deactuating said pump when said timer is deactuated and said switch is open.
