Abstract (en)
An energy monitoring system for a heat pump (100), having a compressor (101), an evaporator (102), an expansion valve (103), and a condenser (104), which form a refrigerant cycle through which the working fluid circulates, comprises: a sensing system, for detecting a first temperature parameter and a second temperature parameter; a memory containing reference data representative of mathematical relations which link the input power and/or the output cooling power to the first and second temperature parameter; a processing unit, for deriving, in real time, an estimated value of the input power and/or of the cooling power from the heat pump (100), based on the first and the second temperature parameter and based on the reference data. The evaporator (102) receives a heat flux in an adjoining space from a fluid (A). The first temperature parameter is representative of a temperature of the working fluid at the evaporator (102) or of the temperature of the fluid (A) which releases the heat flux to the evaporator; the second temperature parameter is representative of the temperature of the exchanging fluid or of the temperature of the working fluid at the condenser.
