Title:
FILTH BLOCKAGE STATE DETERMINATION APPARATUS AND DETERMINATION METHOD FOR CONDENSER
Document Type and Number:
WIPO Patent Application WO/2022/088317
Kind Code:
A1
Abstract:
A filth blockage state determination apparatus for a condenser (1), and a method for determining a filth blockage state of the condenser (1). The filth blockage state determination apparatus comprises: a first detection portion (410), wherein the first detection portion (410) is arranged at a first discharge pipeline (20) to acquire a temperature value T1 of a liquid cooling medium; a second detection portion (420, 420a), wherein the second detection portion (420, 420a) is arranged at a second discharge pipeline (30) to measure parameters of working fluid; and a control portion (430), wherein the control portion (430) is connected to the first detection portion (410) and the second detection portion (420, 420a); the control portion (430) acquires, according to the measured parameters of the working fluid, a temperature value T2 associated with the working fluid; and the control portion (430) calculates the temperature difference between the temperature value T2 and the temperature value T1, and compares the temperature difference with a pre-set temperature difference threshold value, and if the temperature difference is greater than the temperature difference threshold value, it is determined that filth blockage occurs in the condenser (1).
