摘要:
In an air-conditioning system controller provided with a central control unit and a local control unit, the central control unit includes a heat source machine measurement system for measuring an input/output state of a heat source machine, a setting unit for setting air-conditioning condition data on air-conditioning object spaces, an outdoor air measurement system for measuring outdoor air condition data, a total air-conditioning load operating unit, an optimal operating state estimation unit, and a heat source machine control. The total air-conditioning load operating unit calculates a total air-conditioning load or a heat exchange rate of the heat source machine based on chilled water inlet and outlet temperatures and chilled water flow rate of the heat source machine.

An air conditioning control system allows a supply air switching controller to alternately switch outside air control and return air control at a preset switching interval. The supply air switching controller is connected to an air conditioner placed to correspond to each room inside as an air conditioning control subject. The outside air control takes outside air into a temperature/humidity adjustment coil of the air conditioner by opening a first damper provided in the air conditioner in order to adjust an intake volume of the outside air into the air conditioner and by closing a second damper provided in the air conditioner in order to adjust an intake volume of return air from the room inside. The return air control takes the return air from the room inside into the temperature/humidity adjustment coil of the air conditioner by closing the first damper and opening the second damper.

A prepreg is provided capable of being a composite material having suitable high heat resistance, impact resistance, and mechanical properties under high temperature and high humidity conditions. As the matrix resin, a composition including a specific epoxy resin component (A), a specific bifunctional epoxy resin (B), a specific tetrafunctional epoxy resin (C), and a specific aromatic amine compound (D) at specific proportions are used. Particularly, as the epoxy resin component (A), one obtained by mixing and heating a bifunctional epoxy resin (a1), a trifunctional epoxy resin (a2), a phenol compound (a3), and a specific polyamide resin (a4) is used so as to be able to solve the above-described problems.
摘要:
A control for controlling an intake air into an engine is provided. A control valve for adjusting an amount of the intake air into the engine is provided. A desired opening degree of a control valve provided in an intake air passage into the engine is determined based on a clogging coefficient. The clogging coefficient indicates a degree of clogging of the intake air passage. An opening degree of the control valve is controlled to converge to the desired opening degree. The clogging coefficient is updated based on a feedback correction amount for feedback controlling a rotational speed of the engine during idling operation. If a leakage in a blow-by gas passage that is connected between the engine and the intake air passage is detected, the update of the clogging coefficient is prohibited.

An information recognition circuit comprises a plurality of recognition processing units each composed of a neural network. Teacher signals and information signals to be processed are supplied to a plurality of the units, individually so as to obtain output signals by executing individual learning. Thereafter, the plural units are connected to each other so as to construct a large scale information recognition system. Further, in the man-machine interface system, a plurality of operating instruction data are prepared. An operator's face is sensed by a TV camera to extract the factors related to the operator's facial expression. The neural network analogizes operator's feeling on the basis of the extracted factors. In accordance with the guessed results, a specific sort of the operating instruction is selected from a plurality of sorts of the operating instructions, and the selected instruction is displayed as an appropriate instruction for the operator. Further, the one- loop controller for automatizing operation comprises an input interface section for acquiring image information, an image recognition section for recognizing the image using the acquired image information, a control section for calculating control commands according to the image recognition results, and an output interface for outputting control commands to process actuators or subordinate controllers, respectively.

According to one embodiment, a PMV estimating device calculates a PMV value from an average room radiation temperature, room temperature, room humidity, room air velocity, an amount of cloth worn by a person in the room, and an amount of activity of the person in the room. The PMV estimating device includes: indoor solar radiation calculator; solar radiated article temperature estimator; and average radiation temperature estimator. The indoor solar radiation calculator calculates an amount of solar radiation entered into the room. The solar radiated article temperature estimator estimates a temperature of a solar radiated article receiving the solar radiation entered into the room, by using the amount of solar radiation entered into the room calculated by the indoor solar radiation calculator. The average radiation temperature estimator estimates the average room radiation temperature by using the temperature of the solar radiated article estimated by the solar radiated article temperature estimator.
