Abstract: Disclosed is a method for balancing the out-of-balance of a shaft/wheel assembly. The balancing method involves a step of measuring the value of the out-of-balance of a wheel/shaft assembly with respect to a longitudinal axis of the mechanical shaft, and then measuring the position of at least two different target zones present on the surface of the wheel. The method involves removing material from the surface of the vaned wheel in order to reduce the value of the out-of-balance of the shaft/wheel assembly depending on the measurements taken in steps a) and b). In this way, the balancing method is much more precise compared with the prior art.

Abstract: The energy system includes a heat exchanger absorbing heat energy from its environment, and a heat pump transferring energy from the heat exchanger to a heat-consuming circuit. The heat pump includes a regulator arranged so as to regulate a temperature of the heat exchanger at a temperature below a liquefaction and/or freezing temperature of the water vapor of the ambient air. The regulator is also arranged so as to regulate the temperature according to weather conditions, which the heat exchanger is exposed to, such as rain, wind, and sun.
