    • A control system is provided for a modulated heating system including at least one modulating water heater and a controller. A deadband control scheme provides for reduced cycling of the modulating heater when total system heat demand falls between the maximum output of one heater and the sum of the maximum output of that one point and the minimum firing point of the next subsequent heater. Condensation of flue gas products is prevented by monitoring flue exhaust temperature for each heater and controlling the modulation of each heater to maintain a minimum heater output sufficiently high to prevent condensation of flue gas products from that heater. Rapid reaction to changes in system heat demand is provided by sensing changes in flow rate in a primary loop of the system and anticipating resulting changes in temperature thus allowing for change in heater output prior to the time the change in flow rate has fully impacted system temperature.
    • 为包括至少一个调制热水器和控制器的调制加热系统提供控制系统。 死区控制方案提供了当总系统热量需求落在一个加热器的最大输出和该一点的最大输出和下一个后续加热器的最小点火之和之间时调节加热器的循环减少。 通过监测每个加热器的烟道排气温度并控制每个加热器的调节以防止烟道气产品的冷凝,以保持足够高的最小加热器输出,以防止来自加热器的烟道气产品的冷凝。 通过检测系统初级回路中流速的变化并预测温度的变化,从而提高对系统热量需求变化的快速反应,从而允许在流量变化完全影响系统温度的时间之前改变加热器输出 。

    • As discussed herein, a first aspect of the present invention provides a round energy transfer component. The ground energy transfer component can include an outer tube having an upper end and a lower end. The outer tube can be constructed out of generally thermally conductive material. The ground energy transfer component can include an inner tube. The inner tube can be constructed out of generally thermally insulative material. The inner tube can be coupled to the outer tube and positioned generally coaxially with the outer tube to define a generally thermally insulated interior of the inner tube and a channel between the inner tube and the outer tube. The inner tube can have an upper end and a lower end, with the inner tube's lower end defining one or more openings to permit fluid communication between the channel and the interior of the inner tube. The ground energy transfer component can include a base connected to the lower end of the outer tube to substantially seal the lower end of the outer tube. The ground energy transfer component can include first and second connectors coupled to the inner and outer tubes. The first and second connectors can be configured to connect the ground energy transfer component to HVAC pipes of an HVAC system so that HVAC fluid from the HVAC system can flow through the ground energy transfer component. The channel can be configured to create more turbulence in the flowing HVAC fluid than is the interior of the inner tube.

    • In a cogeneration system having three generation units each equipped with a generator and an internal combustion engine, a single hot water tank is prepared for the three generation units to contain hot water heated by exhaust heat of the engine. The temperature of the hot water contained in the tank and a power demand of an electrical load are detected. Then, the number of the generation unit or units to be operated is determined based on the detected power demand when the detected hot water temperature is equal to or less than a first predetermined value, and operation of the generation unit or units determined to be operated is controlled, thereby reducing a space for the installment of the tank and heat loss from the tank.
