Description

Title of the invention: Thermodynamic system with distributed functional continuity

[0001] The system includes an evaporator subdivided into thermodynamically independent zones, an intelligent control module ensuring dynamic redistribution of thermodynamic conditions, self-calibration, self-diagnosis, automatic correction, self-cleaning of the outdoor unit functions, as well as an indicator and automatic adjustment of the fluid charge.

[0002] The present invention relates to an all-electric thermodynamic heating and / or cooling system, in particular a heat pump, designed to operate continuously under real climatic conditions. The invention is based on distributed thermodynamic continuity, enabling the local handling of limiting phenomena without a global system shutdown. Thermodynamic principles and associated formulas

[0003] The instantaneous performance of the system is characterized by the coefficient of performance (COP), defined by the relation: COP = Useful Quotient / Electrical E

[0004] where Qutile represents the useful thermal power delivered to the heating or cooling system, and Pelectric the electrical power absorbed by the compressor and auxiliaries.

[0005] Distributed thermodynamic continuity aims to maximize the real and seasonal COP by keeping the system as close as possible to its optimal operating point, even in the presence of disturbing phenomena.

[0006] The stability of the vacuum is evaluated from the time derivative of the absolute pressure measured in the circuit, according to the relation: AP / At < Stability_threshold

[0007] where AP represents the absolute pressure variation measured by a dedicated sensor during a time interval At. The vacuum is considered to be validated when this condition is satisfied for a predefined duration.

[0008] The automatic adjustment of the effective fluid charge is controlled in order to maintain target superheat (SH) and subcooling (SR) values, defined respectively by: SH = T_evaporator_outlet - T_saturation SR = T_saturation - T_condenser_outlet

[0009] The control module dynamically adjusts the effective fluid charge so as to maintain SH and SR within predefined ranges, ensuring stability, efficiency and protection of the compressor.
