    Abstract: PURPOSE:To raise the temperature of the room quickly to a set point, when the heating operation is started, by forming an opening at an end of a double floor as a passage to the room and by dividing the ejected air into two flows, one being sent through an outlet open to the room and the other being sent through a lower outlet open to an underlying space. CONSTITUTION:When the heating operatio is started, a damper 32 is actuated to divided warmed air into a flow to be sent through a lower outlet 31 and another flow to be sent through an air duct 33 at the start of heating; the warmed air is sent through the lower outlet 31 and through an outlet-at-the-start-of-heating 34. The warmed air ejected through lower outlet 31 flows through an underlying space 36 and is ejected through a vent 37 so that the warmed air warms the living space 24 from under. Simultaneously the warmed air ejected through the outlet-at-the-start-of- heating 34 warms the living space 24 from above so that the temperature can be raised to a set point quickly. In cooling, a blower 28 is designed to rotate oppositely to the rotation for heating; the air flows upward; it is cooled as it passes a heat exchanger 27 and the ejected upward from an upper outlet 30. The cooled air, which has been discharged upward, flows through the underlying space 36 in the double floor 35 and sucked in through the lower outlet 31.

    Abstract: PURPOSE:To improve the reliability and EER of a compressor by regulating the lift of an electric expansion valve according to the degree of superheat of refrigerant in case of no large fluctuation in load, and according to the operational frequency of the compressor in case of large fluctuation in load. CONSTITUTION:The suction temperature is measured by a thermo-sensor 11 and the suction pressure by a pressure sensor 12 to calculate the degree of superheat of the influent coolant. When there is no change in the number of indoor units in operation, the lift of an electric expansion valve 4 is calculated and regulated so as to attain to a specified degree of superheat of the influent coolant in order to operate an air conditioning system at a high efficiency. When the number of the indoor units in operation changes causing a large fluctuation in load, the operational frequency of a compressor 1 is measured to calculate and determine the lift of the electric expansion valve corresponding to the operational frequency, and the electric expansion valve is regulated according to the operational frequency of the compressor 1 for a specified period of time. Thereby, hunting and back flow of the liquid caused by the response characteristics of the electric expansion valve 4 are prevented, so that the reliability of the compressor and EER can be improved.

    Abstract: PURPOSE:To improve the evaporative capability of refrigerant by connecting a refrigerant tube leading out of a gas-liquid separator and an evaporator outlet port to a refrigerant tube with a flow amount regulating valve whose opening degree varies in accordance with dryness detected by a dryness detecting means. CONSTITUTION:A refrigerant gas having a high temperature and a high pressure, which has been compressed by a compressor 1, passes through a refrigerant tube 8 and is condensed and liquefied by a condenser 2. Further, the refrigerant thus treated passes through a refrigerant tube 9 and is adiabatically expanded by a decompressor 3 to be converted into the gas-liquid two-phase refrigerant having a low temperature and a low pressure, and the resultant refrigerant passes through a refrigerant tube 10 to enter a gas-liquid separator 6. The inlet pressure of the decompressor is detected by a pressure sensor 14, the inlet temperature of the decompressor by a temperature sensor 16 and the outlet pressure of the decompressor by a pressure sensor 15, respectively. On the basis of these values thus obtained by the sensors, the outlet dryness of the decompressor is calculated by a dryness detecting means 17, and an opening control for a flow amount regulating valve is carried out by a flow amount regulating valve controlling means 18 based on the dryness, whereby only the saturated gas refrigerant is is led out to a refrigerant tube 12. By this method, the evaporative capability of the refrigerant can be improved.

    Abstract: PROBLEM TO BE SOLVED: To improve a fluid behavior analyzing efficiency of a fluid simulator which simulates a fluid flowing around an object by shortening the grid generating time of the simulator by improving the functions of the simulator for recognizing shape of object and for discriminating fluid and nonfluid area in a calculated area. SOLUTION: An analytical data generating section 3 is provided with a function which projects a hierarchical grid generated by adjusting roughness and fineness in a three-dimensional space upon a plane in the direction of each coordinate axis and defines the intersections of shape surface elements and a Descartes grid by sweeping grid points on the projected plane in the direction of a coordinate axis perpendicular to the projected plane, and based on the generated grid points, scans the intersection of the object surface most adjacent to the grid point in the directions of all coordinate axes and discriminates a fluid area when the inner product values of the normal vectors of the surface elements to which each intersection belongs and the distance vectors toward the grid points from the intersections are not negative and a nonfluid area in the other case. Thus, the grid forming time can be shortened and the fluid behavior analyzing efficiency of the simulator can be improved.
