At the completion of the outage, before resuming operation of the boiler, the ventilation system (11) is secured (64) by stopping (80) the ventilation fan (12), closing (81) the ventilation isolation damper (18), opening (82) the internal isolation damper (19), and starting (83) the induced draft fan (32).

Abstract: The present invention is directed at methods and apparatus for controlling multi-source heating systems. The multi-source heating systems of the present invention may include two or more heat sources such as a heat pump, a furnace, an electric heating strip, or any other suitable heat source. An illustrative system includes a multi-zone, multi-source heating system. The illustrative system may determine which of the multiple sources to use depending on a number of factors. Some illustrative factors include information about zones calling for heat, external environment information, and information about the heat sources. One of the heat sources may be, for example, a heat pump, and a determination of whether to activate the heat pump may include determining the current heating capacity of the heat pump and comparing the heating capacity to the amount of heat needed to satisfy the current heat calls. Methods for determining which of at least two heat sources to use are also provided.

Abstract: A hot-water supply system heats water through heat exchange between high-temperature refrigerant of a heat pump circuit and water of a water circulating circuit. The system is an instantaneous water heater unit for instantaneously heating, at a water heat exchanger, water supplied through a water supply pipe and supplying hot water to a using end unit. Therefore, a large-capacity hot-water storage tank is not needed. Sufficient heat of condensation to heat water can not be produced, because pressure conditions of the heat pump circuit is not stabilized just after the start of operation. Therefore, during a short period of rising time, hot water stored in a hot-water supply tank and water from the water heat exchanger are mixed and the mixture is supplied to keep the hot water at a preset temperature. Therefore, it is possible to use a smaller hot-water supply tank.

Abstract: There are situations in which an operator remains in an operator station of a work machine when an engine of the work machine is inactive. The present invention includes a control system for, and a method of, heating the operator station when the engine is inactive. A heating system of the work machine includes an electrically-powered coolant pump, a power source, and at least one piece of warmed machinery. An operator heat controller is moveable between a first and a second position, and is operable to connect the electrically-powered coolant pump to the power source when the engine is inactive and the operator heat controller is in the first position. Thus, by deactivating the engine and then moving the operator heat controller to the first position, the operator may supply electrical energy to the electrically-powered coolant pump, which is operably coupled to heat the operator station.

Abstract: A heating and/or air-conditioning system for vehicles, preferably passenger vehicles, has a central air-conditioning and/or air-conveying device for conditioning and/or conveying air. In order to achieve optimum air conditioning of the vehicle interior and sufficient freedom of the windows from misting with the most effective energy use possible, the air within the vehicle interior is fed so that, for example, outside air and circulating air are fed into the vehicle interior through dedicated air inlet openings and removed from the vehicle interior through dedicated air outlet openings. The air is guided on closed flow paths in order to achieve separation of circulating air and outside air.
