摘要： PURPOSE:To prevent a refrigerating cycle from being undesirably stopped in the process of starting cooling operation and to detect abnormalities in a chilled water generating circuit. CONSTITUTION:When operation is started, a compressor 20 is turned on and chilled water is checked if its temperature difference DELTAT is not higher than temperature difference upper limit T5, a chilled water circulation pump 7 for cooling is turned on so as to circulate chilled water to a chilled water circulation circuit, and forced operation is effected for a period of a specified forced operation time t1 regardless of the condition of turning off according to chilled water supply temperature T1, chilled water return temperature T2 or the temperature difference DELTAT. If the temperature difference DELTAT has reached the temperature difference upper limit T5 or higher before the elapse of the time the operation is shifted to a state of ordinary chilled water temperature control. If the temperature difference DELTAT is less than T5, the operation is shifted to the state of the chilled water temperature control when the time t1 has elapsed. Then, the elapse of operation start set time t2 from the time of operation start (t1

摘要： PURPOSE:To extend the on-off period of a compressor, and thereby reduce starting power and improve performance coefficient by increasing a difference between upper and lower limit set temperatures as on-time is shortened upon a low load where the on-off period is decreased compared with the case of an ordinary load. CONSTITUTION:A refrigerant which has attained a high temperature by being compressed by a compressor 1 is cooled and condensed through a condenser 2. The refrigerant, after being expanded through an expansion valve 3, cools cold water in an evaporator 4 and returns to the compressor 1. The cold water cooled thereupon is fed to a room machine to cool air in a room. A controller 5 monitors at all times temperature of the cold water based upon a signal from a temperature sensor 6, and on-off controls the compressor 1 such that the temperature of the cold water falls within a range between the upper and lower values. In this case, the control device 5 measures an interval of the on-time of the compressor 1. When a measured time interval is shortened more than the set values, the interval between the upper and lower values is extended.

摘要： PURPOSE:To prevent a funnel from becoming large in size and to attain improvement in a pumping capacity and suppression of noise by a construction wherein a sharply tapered part is provided at the lower end part of a funnel and a water surface is positioned at the sharply tapered part, while a straight tube part is provided in a continuity to the lower end of the sharply tapered part. CONSTITUTION:A funnel 4 is constructed of a gently tapered tubular body 4a shaped like an inverse truncated cone, a sharply tapered tubular body 4b shaped like an inverse truncated cone and provided in a continuity to the lower end part of the tubular body 4a and further a straight tube part 4c provided in continuity to the lower end of the tubular body 4b. A sirocco fan 5 is disposed above the funnel 4 and the funnel 4 is connected to the lower end of a shaft l of the fan so that it rotates horizontally with the fan 5. The lower part of the funnel 4 is immersed in water so that the surface of the water is positioned at the sharply tapered part 4b. According to this constitution, the water in contact with the inner and outer surfaces of the funnel 4 rotates with the rotation of the funnel 4 so that it follows this rotation, rises along the inner surface of the funnel 4 by a centrifugal force and then scatters around from the upper edge of the funnel.

摘要： PURPOSE:To prevent discharged gas from changing into white smoke or prevent the cooling capacity from being lowered by a method wherein the temperature of discharged gas within a discharging cylinder, a refrigerant within a condensing coil or cooling water within a water receptor pan are detected and the number of rotations of a fan motor is controlled in such a way that the temperatures may become constant valUes. CONSTITUTION:In a compression type cooling machine, refrigerant gas got from a compressor B is cooled and condensed at a condensor A and refrigerant liquid is sent to an evaporator D through a capillary tube C. The condensor A is so constructed that a condensing coil 3 of a refrigerant pipe is enclosed with a cylindrical skirt 2, held on a water receptor pan 1 and a discharging cylinder 5 having a fan 4 at its upper part is provided. An inverted-conical water dispersion funnel 6 arranged at a central part of the coil 3 is rotated by a fan motor 8, thereby water within the pan 1 is scraped up with a water scraping vane 10 and dispersed into the coil 3. In this case, the discharged air temperature within the discharging cylinder 5 is detected by a temperature sensor 7, the number of rotations of the fan motor 8 is controlled in response to the detected temperature and the discharging temperature is kept constant to prevent the cooling capacity from being lowered.
