Useful Energy Q


The heat pump toolbox Useful Energy Q calculates the useful energy Q created in a heat pump based on water flow, hot water outlet, and cold water inlet. The block can output either a total single number or per sample basis. It works well with a summation block afterwards to sum multiple outputs.

1xNMxNMxNMxNQFlow [l/m]Hot water outlet [C]Cold water inlet [C]


Each input must be of the same size MxN. The time unit of all inputs should be s in seconds. M should also be minimum 2.

Flow [l/m] is the water flow in liters per minute.

Hot water outlet [C] is the hot water outlet temperature in degrees celsius

Cold water inlet [C] is the cold water inlet temperature in degrees celsius


The output is the calculated useful energy Q created by the heat pump of each n column.


Output ModeSingle Number


Name specifies the name of the block.

Output Mode

Output mode is the type of output the block should send out. It can be Single Number where the entire dataset is converted and outputted as a single number per column. Per Sample is the other type where the conversion is outputted per sample.


Inputs specifies the number of inputs the block has. This cannot be changed.
