A technical handbook for Refrigerant Application
A technical handbook for Refrigerant Application Shows Cooling food in supermarkets or cooling buildings with air-conditioners, reusing waste heat in desuper heaters and heating houses with heat pumps – all examples of the largest application field for SWEP BPHEs, i.e. Refrigerant applications.
The theory behind refrigeration phenomena may seem deep and complicated. The purpose of the refrigerant applications handbook is to make this theory accessible and easier to understand. The handbook is a powerful tool for learning more about the background to heat transfer. You can read the handbook from start to finish, or go directly to chapters of interest.

The most basic rule of heat transfer is that heat always flows from a warmer medium to a colder medium. Heat exchangers are devices to facilitate this heat transfer with the highest possible efficiency.A good heat exchanger is able to transfer energy (heat) from the hot side to the cold side with small thermal losses and high efficiency. Good heat exchangers are typically small vessels with a small pressure drop, and are able to handle small temperature differences between two media.

The heat transfer from one medium to another is controlled by a few simple but fundamental rules:
- There must be a temperature difference in order for energy transfer to take place.
- Energy (heat) will always flow from the warmer medium towards the colder medium.
- The energy (heat) rejected from the warm medium is equal to the heat absorbed by the cold medium plus losses to the surroundings
- In a one-phase heat transfer process, there is no phase change in the media. An example of such a process is a water-to-water application where the water flow on side 1 changes temperature from 30 to 50°C and the flow on side 2 changes temperature from 65 to 45°C, i.e. without a phase change.
