Electrical Chiller
An electrical chiller is a simple variant of a heat pump and is modelled as such: electricity as input and cooling and waste heat as output. For the energy balance to hold, a waste heat export must be modelled.
Note that the waste heat can also be reused as the input of another technology.

Figure 16 Set up and implementation of an electrical chiller to generate cooling and waste heat.
When defining a heat pump in Sympheny, the following steps must be done:
Defining the energy carriers necessary (as displayed in the table under the ‘set-up summary’ section).
Defining the inputs (in this case, electricity) and the outputs (in this case waste heat) of the chiller within the imports & exports tab.
