Patent number: 11371734Abstract: For monitoring an HVAC system (1), HVAC data reporting messages are received and stored in a cloud-based computer system (4). Each HVAC data reporting message includes one or more operation data values included by an HVAC controller (22) of the HVAC system (1). The cloud-based computer system (4) generates (S73) remote diagnoses for a particular HVAC device, using a plurality of HVAC reporting messages received from a plurality of the HVAC controllers (22) from one or more HVAC systems (1). Each remote diagnosis is generated (S73) by using more than one operational data value, included in HVAC reporting messages received (S71) received from HVAC controllers (22) of more than one HVAC systems (1) and/or from at least two different types of operational data values. A diagnosis message which includes a remote diagnosis is transmitted to a diagnosis processing system for the particular HVAC device.Type: GrantFiled: May 31, 2017Date of Patent: June 28, 2022Assignee: BELIMO HOLDING AGInventors: Ronald Aeberhard, Reto Anliker, Stefan Mischler, Frauke Oldewurtel, Forest Reider, Peter Schmidlin, Marc Steiner, Marc Thuillard

Patent number: 10635120Abstract: A method for operating and/or monitoring an HVAC system (10), in which a medium circulating in a primary circuit (26) flows through at least one energy consumer (11, 12, 13), the medium entering with a volume flow (?) through a supply line (14) into the energy consumer (11, 12, 13) at a supply temperature (Tv) and leaving the energy consumer (11, 12, 13) at a return temperature (TR) via a return line (15), and transferring heat or cooling energy to the energy consumer (11, 12, 13) in an energy flow (E). A control unit (21) adaptively operates the system by empirically determining the dependence of the energy flow (F) and/or the temperature difference ?T between supply temperature (Tv) and return temperature (TR) on the volume flow (?) for the energy consumers (11, 12, 13) in a first step, and by operating and/or monitoring the HVAC system (10) according to the determined dependency or dependencies in a second step.Type: GrantFiled: March 19, 2018Date of Patent: April 28, 2020Assignee: BELIMO HOLDING AGInventors: Vinod D'Silva, Mark Nightlinger, Marc Thuillard, Ronald Aeberhard

Patent number: 10627129Abstract: For operating a thermal energy exchanger (1) for exchanging thermal energy between a thermal transfer fluid and air, a plurality of measurement data sets are recorded in a control system (40). The measurement data sets include for a different point in time data values which define a normalized energy transfer that represents the thermal energy transferred in the thermal energy exchanger (1) normalized by one or more normalization variables. The control system (40) calculates for each of the measurement data sets a normalized data point defined by the normalized energy transfer. The control system (40) further determines for the thermal energy exchanger (1) a characteristic energy transfer curve which fits the normalized data points. Normalizing the energy transfer makes it possible to operate the thermal energy exchanger (1) more efficiently over a wider range of changing conditions, as saturation can be prevented using more appropriate fixed or variable thresholds.Type: GrantFiled: July 25, 2016Date of Patent: April 21, 2020Assignee: BELIMO HOLDING AGInventors: Forest Reider, Marc Thuillard, Stefan Mischler, Ronald Aeberhard
