The invention relates to a method for detecting deficiencies in a cooling tower (2) of a thermal facility (1) in operation in a given environment, comprising the implementation of the steps of: (a) measurement, by a plurality of sensors (13), of a set of values of physical parameters relating to the cooling tower (2), at least one of which being an endogenous parameter specific to the operation of the cooling tower (2) and at least one exogenous parameter specific to said environment; (b) calculation, by data processing means (11), of at least one expected optimum value of said endogenous parameter as a function of said values of the physical parameters and a model; (c) determination, by the data processing means (11), of at least one potentially deficient function of the cooling tower (2) as a function of the disparity between the measured value and the expected optimum value of said endogenous parameter and/or the variation of said disparity; (d) testing, by the data processing means (11), of each function of the cooling tower (2) determined as being potentially deficient; and (e) triggering of an alarm, by the data processing means (11), if at least one function of the cooling tower (2) is evaluated as being deficient in the test.

The invention relates to a method for regulating a condenser in a thermal cycle apparatus, in particular in an ORC apparatus, wherein the thermal cycle apparatus comprises a feed pump for conveying liquid working medium with an increase in pressure to an evaporator, the evaporator for evaporating and optionally additionally superheating the working medium with a supply of heat, an expansion machine for generating mechanical energy by expansion of the evaporated working medium, a generator for at least partially converting the mechanical energy into electrical energy, and the condenser for condensing the expanded working medium, and wherein the method comprises the following steps: determining a rotational speed of the generator or of the expansion machine; determining, without the use of a temperature sensor, a temperature of cooling air supplied from the condenser; determining from the determined generator or expansion machine rotational speed and the determined cooling air temperature, a condensation setpoint pressure at which the net electrical power of the thermal cycle apparatus is at a maximum; and controlling or regulating the condensation pressure, with the condensation setpoint pressure as target value, in particular by adjusting a condenser fan rotational speed.

Provided is an apparatus for extracting water from a condenser to the outside for water quality analysis. The apparatus includes an insertion pipe inserted into a condenser, a screw thrust portion including a rotating shaft inserted into the insertion pipe, a screw coupled to one end of the rotating shaft, and a screw thrust portion comprising a power providing portion configured to transmit power to the rotating shaft, and an exhaust pipe provided in the insertion pipe to introduce the water to flow to the outside of the condenser when the water contained in the condenser flows toward a rear side of the screw according to a rotation of the screw.

In one embodiment, a cooling system includes a thermosyphon cooler that cools a cooling fluid through dry cooling and a cooling tower that cools a cooling fluid through evaporative cooling. The thermosyphon cooler uses natural convection to circulate a refrigerant between a shell and tube evaporator and an air cooled condenser. The thermosyphon cooler is located in the cooling system upstream of, and in series with, the cooling tower, and is operated when the thermosyphon cooler is more economically and/or resource efficient to operate than the cooling tower. According to certain embodiments, factors, such as the ambient temperature, the cost of electricity, and the cost of water, among others, are used to determine whether to operate the thermosyphon cooler, the cooling tower, or both.
