Abstract
A device for monitoring the thermal energy consumed by a single unit of a multi-unit building having a central heating and/or cooling space conditioning system. Said device comprising a monitoring system responsive to the temperature levels contained in said single unit and of the space conditioning heat exchanger within said unit and a monitoring circuit which comprises a temperature measuring circuit for monitoring temperature levels. A recording and display circuit being electrically coupled to the temperature measuring circuit to provide a totalization and reading of accumulated temperature levels within a unit during a monitoring interval.
Claims7
A device for monitoring the thermal energy used by a single unit of a multi-unit building having a central space conditioning system said device comprising an energy monitoring circuit having a sensor unit comprising two temperature sensors separated by a solid sensor element, a differencing means to determine the temperature difference between said two temperature sensors, and a recording and display means for the totalization and reading of the energy consumption monitored wherein said sensor unit is thermally coupled to a space conditioning heat exchanger.
