摘要： A method and/or system is provided that compensates for the flow of air through fiberglass insulation. In certain example embodiments, a dynamic heat flow meter or the like is provided for measuring and/or determining any detrimental effects of air flow through insulation such as fiberglass insulation. Once the possible detrimental effects are recognized, an insulation system is adapted (e.g., by providing a foam based insulation in a wall cavity in addition to the fiberglass insulation) to compensate, or substantially compensate, for the effects of air flow through the fiberglass. For instance, a sufficient amount of foam insulation may be provided in a cavity adjacent fiberglass, where the foam blocks or substantially blocks air from flowing through the cavity, thereby compensating for the effects of air flow through fiberglass and permitting the intended R-value to be maintained or substantially maintained.

摘要： A device is provided for measuring heat flux from a test material exposed to a flame. The device is comprised of an elongate element defining a passageway for a fluid, a fluid flowing through the passageway, means for measuring the rate of water flow through the passageway, and a plurality of temperature-sensing elements positioned along the passageway and within the elongate element. The temperature-sensing elements are spaced from one another longitudinally with respect to the passageway. A method of evaluating fire hazards of materials in standard tests is provided which comprises measuring heat flux distribution in test fires at the moment when sprinklers would have sensed the fire and be activated, and determining the rate of sprinkler water delivery rate that will absorb the heat flux, thus controlling spread of the fire.

摘要： The invention relates to a method and to an apparatus for monitoring the heat transfer and therefore the efficiency of a condenser. A water column is formed by shutting off a condenser pipe which assumes the steam temperature T.sub.s and whose outflow time after the resumption of the flow can be utilized for measuring the flow velocity. With the knowledge of the water inlet temperature T.sub.1 and the water outlet temperature T.sub.2 measured on the same condenser pipe, it is possible to very accurately establish the heat transfer through the measured condenser pipe, so that on the basis thereof it is e.g. possible to operate a cleaning system with foam rubber balls. Thus, each fraction of the possible efficiency of the condenser is exploited.

摘要： A device for measuring the relative efficiency of a heat pump whose design efficiency increases in proportion to the outdoor temperature. Temperature sensitive diodes connected to a differential amplifier are inserted in the return air stream and supply air stream of a heat pump in order to measure the air temperature increase across the indoor coil. A third temperature sensitive diode connected to a second differential amplifier is placed outdoors in order to measure the outdoor temperature. The outputs of the first two differential amplifiers are combined and then subtracted from a fixed value signal by a third amplifier in order to produce an output which is proportional to the relative efficiency of the heat pump at the outdoor temperature.
