  • Patent number: 11891309
    Abstract: A method of controlling cooling water treatment at a cooling tower may involve measuring operating data of one or more downstream heat exchangers that receive cooling water from the cooling tower. For example, the inlet and outlet temperatures of both the hot and cold streams of a downstream heat exchanger may be measured, optionally along with a flow rate of the cooling water stream passing through the heat exchanger. Data from the streams passing through the heat exchanger may be used to determine a heat transfer efficiency for the heat exchanger. The heat transfer efficiency can be trended over a period of time and changes in the trend detected to identify cooling water fouling issues. A chemical additive selected to reduce, eliminate, or otherwise control the cooling water fouling can be controlled based on the changes in heat transfer efficiency detected at the downstream heat exchanger.

  • Patent number: 11889963
    Abstract: An automated cleaning machine may include one or more short cleaning cycles in which the duration of a cleaning cycle is shortened relative to the duration of a default cleaning cycle. During a short cleaning cycle, other cleaning cycle parameters may also be adjusted to ensure that the articles subjected to the short cleaning cycle are adequately cleaned and sanitized. For example, the wash temperature, rinse temperature, and/or cleaning product amounts or concentrations, may be adjusted to account for the shortened duration of the cleaning cycle. The automated cleaning machine may further include one or more short cycle mode(s) during which short cleaning cycle parameters are used and one or more default cycle mode(s) during which default cleaning cycle parameters are used.
