It is possible to connect several ChillHeat heat pumps connected in series for an even
higher capacity heating or cooling solution. Automation is an important feature in all
ChillHeat products. A versatile automation system enables energy-efficient and easy
ChillHeat operation.

There are three closed circuits running within or through the heat pump:
● cooling circuit
● refrigerant circuit
● heating circuit.
The ChillHeat pump's operation is based on the vaporisation and condensation of the
refrigerant circulating within the pump.
The cooling circuit is used for collecting heat energy. As the fluid travels along the
circuit, it collects heat energy, which causes the fluid temperature to rise. The fluid
completes its circuit by returning to the evaporator and releasing the heat energy into
the refrigerant, which circulates between the evaporator and the condenser.
When the refrigerant is in the evaporator, it is colder than the secondary refrigerant,
so the heat energy transfer from fluid into refrigerant can take place. The heat transfer
raises the temperature of the refrigerant up to the point where it becomes gaseous.
The gaseous refrigerant is then led into a compressors, which compresses it into
a high pressure. As the pressure of the gaseous refrigerant increases, so does its
temperature.
