Title: Method for detecting amount of ice in ice heat storage tank
Inventor: YOSHIDA NAOTAKA
IPC: G01N9/12
Filed: 1989-11-22
Abstract: PURPOSE:To measure the amount of ice in an ice heat storage tank accurately by providing a float having the specific gravity smaller than the specific gravity of water in the ice storage tank, and measuring the floating height of the float. CONSTITUTION:When water is injected into an ice heat storage tank 1, a float 22 floats on the water surface. With the floatation of the float 22, a piece of wire 21 is made to extend from a reel-type potentiometer 20 through fixed pulleys 23 and 23. The length of the wire 21 between the meter 20 and the float 22 is obtained based on the extending length of the wire 21. The relationship between the length of the wire 21 and the height of the water layer is obtained. Then, the water is the ice heat storage tank 1 is sent into an ice making machine 2 with a pump. The manufacturing of crushed ice pieces is started. The crushed ice pieces 3 are inputted into the ice heat storage tank 1 together with the unfrozen water. When the ice making steps advance and the stored amount of the crushed ice pieces 3 is increased, the floating position of the float is lowered. At this time, the wire 21 connected to the float 22 is wound into the meter 20 through the pulleys 23 and 23. The length of the wire 21 between the meter 20 and the float 22 is obtained based on the wound amount. The height of the water layer is obtained from the length.

Abstract: PROBLEM TO BE SOLVED: To enable an operation for a long period of time without replacing a filter by a method wherein foreign matters in a coolant are captured by a filter of a cooling system loop, and when the filter is clogged, the coolant is reversely passed through the filter to push out the matters to capture the matters by means of a filter in a bypass line and a part of the coolant is caused to flow reversely thereby to store the matters in a return tank. SOLUTION: In a cooling system loop for a spaceship, a filter 3 is fitted in a coolant line 2 to capture foreign matters in the coolant. And when the filter 13 is clogged, the coolant is caused to reversely flow to push out foreign matters to send them into a cooling system bypass loop 8, where the matters are captured by a cleaning filter 9. Further, a part of coolant, during a normal operation, is caused to reversely flow to the filter 9 and the foreign matters pushed out of the filter 9 are stored in a return tank 11 from an auxiliary coolant bypass line 13. Consequently the operation of the loop can be continued for a long period of time and a cooling system loop for thermal, control of a spaceship of the long residence type can be obtained.
