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： PURPOSE:To manufacture overcooled water stably by a method wherein water is conducted continuously into a header vessel, provided with a multitude of heat transfer tubes arranged vertically and positioned above a cooler, to keep the amount of water in the vessel so sufficient that the inside of the header vessel will never become a negative pressure. CONSTITUTION:Water in a heat accumulating tank 1 is supplied to an overcooler 2 by a pump 3 through a water passage 4 and is discharged into atmosphere from the overcooler 2 as overcooled water 5 having a temperature lower than 0 deg.C, then, is collided against a dispersing plate 6 and overcooled condition is released by the shock of dropping from the dispersing plate 6 whereby the overcooled water becomes fine ices and sherbet type ice 7 is reserved in the heat accumulating tank 1. When a vacuum pressure is produced in the header vessel 11 due to suction effect by dropping water or the inducing of air from the opening end 15 of a heat transfer tube upon the downflow of water, supplied into the header vessel 11 of the overcooler 2, through the heat transfer tube 9, variety is generated in the degree of overcooling of the overcooled water. Accordingly, the amount of water, which is sufficient to maintain the inside of the header vessel 11 at a positive pressure, is poured forcibly and continuously by the pump 3 by pressure whereby freezing can be avoided.

摘要： PURPOSE:To continuously make supercooled water by mounting a pump at a conduit from a reservoir to an evaporator, and feeding a larger amount of liquid refrigerant than evaporating amount of the refrigerant in the evaporator from the reservoir into the evaporator by the pump. CONSTITUTION:Return refrigerant from an evaporator 10 is received by a reservoir 13, and returned to a compressor 14. Liquid refrigerant at an output side of a condenser 15 is introduced through an expansion valve 16, liquid refrigerant separated from gas refrigerant in the reservoir 13 is forcibly sent to the evaporator 10 by a pump 17. Thus, since several times of evaporated amount of the liquid refrigerant can be sent into the evaporator 10, its heat transfer efficiency is improved, and uniform heat transfer can be performed. In this manner, supercooled water can be continuously made irrespective of the quantity and temperature of the water to be supplied into a heat transfer tube 9 of the evaporator 10.
