摘要： PURPOSE:To make a wind speed distribution of an air flow in an underfloor chamber uniform by only a simple execution in a floor diffusing air conditioning system in which an underfloor space is used as a conditioned air supply underfloor chamber and the air is supplied from diffusers provided at a floor into a room. CONSTITUTION:A diffusing chamber 1 for supplying conditioned air from an air conditioner into an underfloor chamber 2 is connected to one side surface of the chamber 2. A diffusing plate 3 disposed perpendicularly to an air supplying direction is installed on a bottom in the chamber 2. A width (w) of the chamber 1 is set to 1/3 or more of a width W of the chamber 2, a height (h) of the plate 3 is set to 1/2 of a height H of the chamber 2, and a length L of the plate 3 is set to 2/3 of the width W of the chamber 1. Thus, an air flow from the diffusing chamber is collided with the plate, then suitably divided laterally and upward, and a wind speed distribution of the air flow in the underfloor chamber is made uniform.

摘要： PURPOSE:To suppress unevenness of diffused air flow rates to low without providing dampers at respective diffusers by lowering a height of an underfloor chamber in an air conditioning system in which an underfloor space is used as a conditioned air supply underfloor chamber and the air is supplied from the diffusers provided at a floor into a room. CONSTITUTION:Filters 41, 45 are respectively installed in diffusers 20 at an underfloor chamber. Conditioned air in the chamber is supplied into a room through the filters 41, 45. The filters used for all the diffusers have the same specifications, and static pressure performances of the filters 41, 45 are suitably selected. A passing resistance is increased by adding the filters, an outlet resistance coefficient is increased, and unevenness of diffused air flow rates is reduced.

摘要： PROBLEM TO BE SOLVED: To drastically improve the dehumidifying capacity of a desiccant air conditioner in a system comprising the combination of a gas turbine for the generation of electricity used by a cogeneration and the desiccant air conditioner. SOLUTION: High temperature exhaust gas EX from a gas turbine 1 for the generation of electricity is mixed with outer air OA and introduced into the regenerative part 12b of the dehumidifying rotor 12 of a desiccant air conditioner 1. The low humidity and high temperature air, which passes, through the dehumidifying part 12b of the dehumidifying rotor 12, is cooled by a cooling coil 16 and then, used for the cooling load of a room R. Water warmed by the cooling coil 16 is heat exchanged by a water to water heat exchanger with the raw water of a hot-water supply. With this, the warmed raw water is used for the hot-water supply.

摘要： PROBLEM TO BE SOLVED: To improve accuracy at an initial stage of monitoring when detecting a malfunction of a bearing by frequency analysis of vibration acceleration. SOLUTION: In this method, a vibration acceleration from a bearing part of a rotating apparatus is measured, the power spectrum of a frequency component is obtained by fast Fourier transform, and a vibration acceleration of a pilot frequency is extracted from the power spectrum for detecting a malfunction of a bearing attached to the bearing part based upon a degree of increase from normal times. Before the fast Fourier transform, discrete wavelet transformation is performed on the vibration acceleration at a digital filter 31 for determining wavelet coefficients, those of the wavelet coefficients exceeding a threshold set from a value measured during monitoring is removed, and inverse discrete wavelet transformation is performed on the wavelet coefficients after the removal for obtaining a corrected vibration acceleration.

摘要： PROBLEM TO BE SOLVED: To eliminate the noise from a ventilation having a large sectional area by an active silencer. SOLUTION: A plurality of active silencers 1 is mounted on a support frame 14 continuously provided on a duct 11 through a rubber vibration isolator 15. The silencer 1 is connected to an opening 123 with its microphone 3 side as the partitioning wall 2 side. Although B1 or B2 directional ventilation is allowed, the noise in an arrowed direction A entering into the case 2 is collected by a microphone, converted into an interference sound, which is then released through a speaker 4 to interfere with the noise, whereby the noise is eliminated. The noise C out of the case 2 is interrupted by a partition wall 12.

摘要： PROBLEM TO BE SOLVED: To detect a hard-to-cool state during emergency operation period at an early stage by applying time being obtained by subtracting reference time from lapse time from start to specific time to a standard exit temperature operation expression as lapse time and using it as a judgment reference when detecting an operation state. SOLUTION: A pipe 1b for passing water to be cooled is installed in an evaporator 14, and an exit temperature sensor 17 for measuring exit temperature T0 of cold water is provided at the cold water exit of the pipe 1b. By comparing the actual exit temperature with a reference exit temperature, the operation state of a refrigerator can be detected. When an actual exit temperature Tw is equal to or less than a first reference exit temperature Twm, it is judged that the situation is normal. On the other hand, when the temperature is higher than the first reference exit temperature Twm, it is compared with a second reference exit temperature Twm. Then, when the temperature is equal to or less than it, it is judged that the situation requires 'caution'. Then, when the temperature is higher than the second reference exit temperature Twm, it is judged that the situation is 'abnormal'. In this case, various kinds of countermeasures need to be taken by a manager or the like.

摘要： PURPOSE: To operate a heating tower system in the most energy conserving state by so controlling the concentration drive operation that brine concentration becomes a set range by using the estimated value of the outdoor air wet bulb temperature and the estimated value of the outdoor air absolute humidity. CONSTITUTION: Brine in a lower water tank 7 is heated to the outdoor air temperature or higher by a heat exchanger 16, brought into gas-liquid contact with the outdoor air in a heating tower 1, and hence the moisture in the brine is evaporated to the outdoor air to be concentrated. In this case, the outdoor air wet bulb temperature is directly estimated, and the concentration drive operation is so controlled that the brine concentration becomes a set range by using the estimated value and the estimated value of the outdoor air absolute humidity. When the outdoor air wet bulb temperature is estimated, the highest and lowest wet bulb temperatures of the next day are estimated from the data of past several days, the outdoor air temperature and the absolute humidity at 21 o'clock of that day, and the estimated value of each time is calculated based on one day pattern. Thus, the system can be operated with the most energy conservation.
