An optimal gas-fired heating system

An Optimal Gas-Fired Heating System* Un syst6me optimal de chauffage au gaz Ein optimales Gasheizungssystem

-Utilizing a prescribed system configuration, this paper discusses the mathematical models of the system components used and formulates a method for controlling a domestic heating system in accordance to a prescribed criterion. The optimal problem treated is one of reducing the room temperature deviation from a prescribed reference value to zero, while at the same time minimizing the value of s...

Optimal operation strategy of the hybrid heating system composed of centrifugal heat pumps and gas boilers

Centrifugal heat pump has to be coupled with gas boiler to supply high temperature water in radiator heating system. Regarding to hybrid heating system (HHS), operation strategy has significant impact on its annual energy consumption and cost. In this paper, the optimal operation strategy of the HHS composed of sewage-source centrifugal heat pumps and gas boilers was analyzed. Firstly, the perf...

Theoretical Investigation of Consumption Patterns Effect on Optimal Orientation of Collector in Solar Water Heating System

One of the subjects in solar water heater design is considering distribution of hot water consumption during the day. For example, each of the household, commercial, office, school, and industrial consumptions have a particular distribution of hot water consumption named pattern in this article. In solar computation principles, the effect of longitude, latitude, and altitude on collector angle ...
