Title:
TEMPERATURE CONTROL ELEMENT FOR ANTI-ICING THAT MATCHES HEAT LOSS CHARACTERISTICS OF ITEM BEING CONTROLLED
Document Type and Number:
WIPO Patent Application WO/2019/016601
Kind Code:
A3
Abstract:
A deicing system may include one or more walkway cassettes, a temperature control element, and a control unit. Each walkway cassette may include a casing and a heat tracing cable in good thermal contact with the casing. The temperature control element may include a comparatively smaller casing and a heat tracing cable in good thermal contact with the casing, and may exhibit similar heat loss characteristics to the walkway cassettes. The temperature control element may include a temperature sensor on a top surface of its casing, which may generate temperature data and send the temperature data to the control unit. The control unit may provide power to the temperature control element and the walkway cassette(s) in parallel based on the temperature data. The temperature control element may be placed in proximity to the walkway cassette(s), and may be exposed to substantially the same environmental conditions as the walkway cassettes.
