DEVICE INSTALLABLE IN AN AIR CONDITIONING AND / OR HEATING SYSTEM, AIR CONDITIONING AND / OR HEATING SYSTEM INCLUDING THE DEVICE AND METHOD OF CONTROLLING THE DEVICE

摘要

The present invention relates to an assembly installable in an air conditioning and/or heating system of a room. The assembly comprises a body (7) having an inlet opening (7a), an outlet opening (7z) and at least one channel (70) which places the inlet opening (7a) in fluid communication with the outlet opening (7z). An orifice is arranged in the body (7) and is shaped in such a way that when a flow runs through the channel (70) between the inlet opening (7a) and the outlet opening (7z), a pressure difference is generated between the first region (7p) and the second region (7s) within the body (7), the first region (7p) being located upstream of the orifice, the second region (7s) being located downstream of the orifice. The assembly further comprises a meter (1) for detecting said pressure difference and a variator of at least one geometric feature of the orifice, the variator being able to arrange the orifice in a plurality of different configurations, each corresponding to a respective geometric feature of the orifice. The present invention further relates to a control method of the assembly and to an air conditioning and/or heating system of a room comprising the assembly.
