Abstract:
A water heating system uses a heated fluid storage tank to deliver a continuous supply of water heated to a desired temperature, such as between 100°-130°F. The system also includes a furnace with altitude-sensitive control circuitry to provide multiple sources of heat for the heating system in the most effective way given the altitude at which the system is located. The system also includes a micro-controller that adjusts certain system components in response to changes in atmospheric pressure conditions that are measured by an atmospheric-pressure sensor component. There is also an automatic-air-bleeder subsystem with an optical or ultrasonic sensor mounted adjacent a suitable air accumulator. Also included is an air-release solenoid and a fuel return line.
Abstract:
The invention relates to a process and device for monitoring the operation of flueless heaters and rendering it safe, with special regard to indoor paraffin heaters within and beyond the normal range of operation. If the heater goes beyond the normal range the danger arises of incomplete combustion with a concomitant reduction in the oxygen content and rise in the carbon dioxide content in the room. It is the purpose of the invention to facilitate extremely accurate and rapid monitoring of the CO2 content of the air in the room and especially to ensure, regardless of the burner flame height, that the operation of the paraffin heater can be monitored and kept safe independently of any radiation-sensitive detection of the flame height. This is achieved by the invention in that the proportion of O2 in the burner exhaust gas within the paraffin heater is sensitively detected and used as a measure for monitoring the CO2 content of the air in the room and converted into a voltage signal used as a control signal, whereby, when the burner is operated beyond a predetermined flame height range, the sensitive O2 detection is used both to restore the normal heating conditions and to monitor running on the lowest flame, while a warning signal is generated and the burner is automatically turned off after a delay at a predetermined first or second, lower, O2 content of the burner exhaust gas, corresponding to predetermined CO2 contents of the air in the room. It is also possible sensitively to detect the CO content of the burner exhaust gas within the paraffin heater and use it as a measure of the CO2 content of the air in the room and convert it into a corresponding control signal.

Dispositif de combustion a combustible liquide servant a vaporiser et a bruler un combustible liquide, et plus particulierement dispositif de securite pour le dispositif de combustion a combustible liquide du type dechargeant les gaz d'echappement de la combustion dans une chambre. Le dispositif de combustion a combustible liquide de ce type diminue la temperature du gaz d'echappement lorsque la concentration en oxygene de l'air de combustion diminue, ou le degre de combustion diminue a cause du goudron se deposant sur la meche particulierement dans le dispositif de combustion du type a meche, tout en augmentant la temperature du gaz d'echappement lorsque se produit une combustion inverse provoquee par un courant inverse. Ce dispositif de combustion de securite utilise les changements de la temperature du gaz d'echappement produit par l'un des etats anormaux decrits pour detecter le point ou la difference entre les temperatures detectees par un detecteur de temperature (35) de gaz d'echappement et un detecteur de temperature de la chambre (34) depasse ou devient inferieure a une valeur predeterminee, ce qui permet d'arreter la combustion ou de produire une alarme. Lorsque la temperature du gaz d'echappement est diminuee, le dispositif de combustion de securite assure une securite elevee en augmentant la quantite de chaleur produite par un radiateur electrique (41) pour accelerer la vaporisation et la combustion du combustible necessaires pour empecher une interruption prematuree de la combustion a cause d'un ralentissement excessif de la combustion.

Abstract:
A heat management system (10) is capable of managing unlimited hydronic heat sources (16) and unlimited heating zones (18), each located within a desired area and each controlled by temperature sensors (32). The system (10) uses plural system heating sources (16) to heat a heating solution (preferable glycol-based) that is either heated directly or through a liquid-to-liquid heat exchanger. The heating solution is passed through various plumbing configurations to heat domestic water for users and to heat zones or areas in which user will live. The heat management system (10) of the invention may be used for several applications including RV, marine and home hot water and heating applications.
