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： PROBLEM TO BE SOLVED: To provide an apparatus for preventing dew drops which has enough strength to prevent the falling of a case main body even when a blow molding method is used for manufacture, and has a small number of assembling parts. SOLUTION: Reinforcing ribs 15 are molded integrally in the inside wall close to the opening part of the case main body 10. Zigzag passage partition walls 11, 12, and 13 formed in the case main body 10 are formed by making the tip parts of partition wall constituent pieces 111, 121, and 131 of a pair which are molded integrally on both opposite side walls 10a of the case main body 10 butt each other. The partition wall 11, below which dew drops passes, is formed so that each of its partition wall constituent pieces 111 of a pair is lowered from the protruding base end part 111b toward the protruding tip part 111a. Therefore, a ventilation space is formed above the partition wall 11, and the protruding base end part 111b is formed integrally in sequence to the reinforcing ribs 15.

摘要： PURPOSE:To alleviate a load to be applied to a bearing, to enhance a pumping efficiency and to reduce noise by suppressing a shaft fluctuation and vibration of a sprinkling funnel. CONSTITUTION:An evaporation type condenser comprises a condensing heat exchanger 1, a blower 2, a sprinkling funnel 3, a drain pan 4, and a shaft joint 9 as a universal joint provided at a lower end of a rotary shaft 8 of a motor 5 of the blower 2, wherein an upper end of a funnel shaft 10 protruding from an upper end of the funnel is connected to the shaft joint. The shaft joint is formed substantially in a recess shape having a pair of legs 91, at which grooves opened at lower ends are formed, both ends of a pin passed through the upper end of the funnel shaft are engaged with the grooves to form the universal joint. An inner race 121 on the way of the funnel shaft is fixed at its lower surface in a spherical state, engaged with a bearing surface of a spherical shape formed on an outer race 122 supported to an upper center by a support frame 14 to form a bearing 12 or the inner and outer races, thereby supporting a weight of the funnel 3 and inclining an axis of the funnel shaft.

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： PROBLEM TO BE SOLVED: To maintain good CO detection sensitivity for a long period of time, by determining the timing of a heat cleaning based on a prescribed measuring time, in the case where a CO detection element for catalytic reaction to CO gas in exhaust gas is suitably raised of the temperature thereof for heat cleaning of the CO detection element. SOLUTION: A controller 14 of a water heater which is a combustor controls the operation of the water heater by a water heater control part 19 via various driving circuits 20 to 22 based on the CO concentration in exhaust gas detected by a CO sensor 16. A CO sensor control part 25 of the CO sensor 16 increases the electric power to a CO detection element 17 by means of a CO detection element driving circuit 24 based on a command signal from the water heater control part 19 for heat cleaning thereof. In this case, the water heater control part 19 is equipped with a fixed time timer 26, in the case where one combustion or more occurred within the fixed time measured by the fixed time timer, heat cleaning of the CO sensor 16 is accomplished by outputting the command signal from the water heater control part 19.
