The way for your home to be reliably warm

The way for your home to be reliably warm

Thermal heat pumps are amongst the most effective heating and warm water preparation systems, as they make use of the warmth from the sun collected in the air, in the ground or in groundwater. Buildings may be heated all year round with thermal heat pumps in an environmentally friendly manner. Oil burners and boilers are thus made redundant. In times of constantly rising oil and gas prices it is the perfect alternative - money saving and resource-friendly heating.


A thermal heat pump functions like a refrigerator, only the other way around. The operating principle of a heat pump may simply be described as follows: heat pumps take warmth from the air, water or the ground, and run it to the heating system. A heat pump may even produce enough warmth for heating even during outside temperatures below zero. It transforms environmental warmth at low temperatures into warmth of a higher temperature, meaning - from air with a temperature of 10 °C it is able to produce, for example, warm water with a temperature of 35 °C.


In order for this process to be possible, the thermal heat pump is made up of several important components:

  • Evaporator: This unit takes an amount of the warmth from the environment (air, ground or ground water) and transfers it to the heat transfer medium (refrigerant or brine).
  • Compressor: It compresses the heat transfer medium and 'pumps' it up to a higher compression or temperature level, in order to make the collected environmental warmth usable for heating or cooling needs.
  • Condenser: This is where the energy collected in the heat transfer medium is transferred to the heating system. The heat transfer medium cools.
  • Expansion valve: The expansion valve enables reduces the pressure of the heat transfer medium. The pressure drops considerably.

The NDA® air thermal heat pump in action

The air thermal heat pump converts the energy stored in the surrounding air into usable heating energy. The warmth taken from the air is conveyed to the heating system.

 

The evaporator (heat exchanger) is fed outside air from the underside to the top side through the use of a ventilator. Thus the air cools. The heat transfer medium (cooling medium) circulates in the evaporator and takes up the warmth collected from the air. Thus the cooling medium evaporates.

After the evaporator, the cooling medium, now in the gaseous phase, enters the compressor, where the working pressure is raised, and thanks to which the taken warmth may be used for heating purposes.

This usable warmth is transferred to the heating system water in the condenser - here the cooling medium cools and turns into liquid again.

 

Before the process starts again, the pressure is reduced using the expansion valve.
