摘要： PURPOSE:To prevent generation of discomfort sound and a variation in a pumping amount by a simple structure by standing a cylindrical metal gauze concentrically with a funnel from a bottom of a water pan at inside or/and outside of an end of the funnel. CONSTITUTION:A condenser body 1 having a top late 1a and a cylindrical skirt 1b is arranged above a water pan 2. a cylindrical stainless steel gauze 7 is so stood to protrude at its upper end from a horizontal surface as to surround a lower part of a funnel 4 at a center of the pan 2. The funnel 4 is mounted at a shaft of a fan motor 11 and rotatably driven together with a fan 5. Accordingly, water in the pan 2 tends to form a vortex flow due to recessing at a center by a centrifugal force, but the gauze 7 becomes a resistance for the vortex flow to suppress generation of the vortex flow, thereby preventing generation of noise due to the vortex flow and further suppressing a variation in a water level near the center of the pan 2 by the vortex flow, and hence a variation in a pumping amount can be prevented.

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： PROBLEM TO BE SOLVED: To provide a liquid leak detector for a liquid treating device capable of detecting a small amount of leaking liquid and capable of ensuring long-term detection reliability. SOLUTION: A preliminary chamber YB is formed in a communication conduit RT connecting a closed conduit JR to a liquid supply part 21 which supplies the conduit JR with liquid for replenishment. Normally, the chamber YB is filled with the liquid and the air is not introduced thereinto. The amount of liquid that can flow from the supply part 21 to the chamber YB per unit time is limited to a value smaller than the amount of liquid that can flow from the chamber YB to the conduit JR per unit time. When a liquid leakage occurs in the conduit JR, the liquid in the chamber YB flows into the conduit JR and the amount of the liquid in the chamber YB correspondingly decreases, thereby introducing the air into the chamber YB. A detection means 24 for liquid leak detection detects that the air is being introduced into the chamber YB, thereby detecting the liquid leakage.
