Embodiment Construction
[0024] Referring to the drawings, 1 shows generally and diagrammatically a heating and / or conditioning system incorporating a fluid circulation pump 2 implemented in accordance with the invention.
[0025] The pump 2 is preferably of the synchronous type, ie operated in rotation by a synchronous electric motor 12 comprising a permanent magnet rotor 14 . The internal structure of the synchronous motor 12 used to operate the pump is in figure 2 shown and will be explained below.
[0026] The heating system 1 comprises a closed hydraulic circuit 6 , which will be defined below as the main body, equipped with various heating elements 7 .
[0027] The hydraulic circuit 6 is equipped with a series of synchronous circulation pump 2, main body heat exchanger 3, namely a boiler, and heating element 7.
[0028] In connection with the part of the circuit provided with the heating element 7, a second heat exchanger 5 is provided to supply heat to a sanitary circuit 9, for example a cir...

The present invention relates to a method for measuring a parameter characteristic of a heating and / or conditioning system (1) equipped with a primary hydraulic circuit (6) and a secondary hydraulic circuit (9) and wherein at least one operative fluid circulation pump (2) is provided operated by an electric motor and driven by a control electronic device (10). The method provides: a starting measure of the flow rate of the circulating operative fluid carried out with closed delivery, immediately downstream the pump; a subsequent measure of the flow rate of the circulating operative fluid in the sole secondary hydraulic circuit (9); the first and the second measure being carried out with means associated to the control device (10) of the pump (2) so as to output an electric signal correlated with the percentage of additive of the circulating operative fluid or with a variation of the calorific power of the system. <IMAGE>
Description
technical field [0001] The invention relates more generally to a fluid circulation pump, for example of the type installed in heating and / or conditioning systems. [0002] The invention relates to a method for measuring characteristic parameters of a heating and / or regulating system. The description below is for the purpose of illustration in relation to the scope of this application. Background technique [0003] As is well known to those familiar with the field, fluid circulation pumps installed in heating and / or regulating systems, also known as circulation devices, generally employ electric motors of the asynchronous type with windings and phase chokes. [0004] The speed of these devices is regulated by the control unit based on the instantaneous value of the variable measured from the overall system. In particular, sensors are provided for measuring circulating fluid flow rate, temperature and pressure. [0005] For example, the asynchronous motors currently used in...
