Technology in and around the heat pump
The heat pump consists of four main parts:
1. Evaporator
The evaporator evaporates the refrigerant to gas and transfers heat
from the heat transfer fluid to the refrigerant circuit.
2. Condenser
The condenser condenses the vapour to fluid again and transfers the
heat to the heating system.
3. Expansion valve
Lowers the pressure of the refrigerant.
4. Compressor
The compressor increases the pressure of the refrigerant.
These four main parts are linked in three circuits. A refrigerant
circulates in the heat pump, which in some parts of the circuit is in a
liquid state and in other parts in a gas state. Read more about the
properties of the refrigerant in the text box to the right.
See the detailed description of the technologies used in the heat pump
on the next page.
Technical information
Boiling point in relation to the
pressure:
The boiling point of different liquids
varies with pressure, the higher the
pressure, the higher the boiling point.
For example, water boils at +100ºC at
normal pressure. Double the pressure
and water boils at +120ºC. Half the
pressure and water then boils at +80ºC.
The refrigerant in the heat pump acts
in the same way. The boiling point
changes when the pressure changes.
However, the boiling point of the
refrigerant is as low as -40ºC at
atmospheric pressure. Consequently,
it is also suitable for low heat source
temperatures.
This is how your heat pump works
The heat pump collects stored Solar energy
The heat pump has been manufactured for easy and reliable use as well as to provide your house with inexpensive and
environment friendly heating. The easiest way to describe how a heat pump works is to say it works like a refrigerator, but in
reverse. In a refrigerator, heat is moved from the inside to the outside. In a heat pump, heat stored in the ground, rock or
water, is moved into the house. The heat pump collects a few degrees of the stored Solar energy. The heat is transferred into
the house via a collector system. The temperature is then increased in the heat pump and the heat is distributed to the
house heating system.
