Kind Code:
A1
Abstract:
A controller(1) for an HVAC unit(2) for an indoor space(3) separated from an outdoor space(4) by a building envelope(5). The controller(1) comprises a power measurement device(6) for measuring an input power being delivered to the HVAC unit(2). The input power corresponds to a nominal heat transfer provided by the HVAC unit(2). An estimation module(7) calculates a target heat transfer between the HVAC unit(2) and the indoor space(3). The target heat transfer is calculated based on a heat transfer load comprising an external heat transfer between the indoor space(3) and outdoor space(4) calculated in accordance with an ambient indoor temperature of the indoor space(3)， an ambient outdoor temperature of the outdoor space(4), and a thermal model(8) of the building envelope(5). A control unit(9) monitors or controls the HVAC unit(2) based on one or both of the input power and the target heat transfer.
