Title:
Heat loss measurement system for steam piping, its arithmetic unit
Document Type and Number:
Japanese Patent JP6357954
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To allow a heat loss of a steam pipe to be determined without a steam flowmeter, etc.SOLUTION: A heat loss measurement system of a steam pipe comprises: a first measurement unit 10 for measuring a flow rate and a temperature of cold water for a refrigerator; a second measurement unit 20 for measuring a temperature of steam related to the steam pipe; and a calculation device 30. A refrigeration capacity calculation unit 31 of the calculation device 30 determines a refrigeration capacity of the refrigerator from a measurement result obtained by the first measurement unit 10. A steam flow rate estimation unit 32 estimates a flow rate of the steam related to the steam pipe on the basis of the determined refrigeration capacity and characteristic data of the refrigerator. Thereby, a heat loss calculation unit 33 can calculate a heat loss related to the steam pipe.SELECTED DRAWING: Figure 1
