Coaxial heat exchangers should preferably be operated in counter-flow operation. The inner tubes as well as the jacket tube and brazed T-fittings are made of Cu-DHP.
Condensers WKC are installed so that the liquefied refrigerant is free to drain away to the bottom. The hot gaseous refrigerant enters the jacket space at the top, whereas the cooling medium (e.g. water) enters the inner tube(s). Coaxial condensers are also installed standing on the windings (winding axis horizontal). If an application requires several condensers to be connected in parallel, then the tubing should be designed in such a way that each condenser can be supplied with even pressure on both the refrigerant side and the cooling medium side.
The routing of the hot-gas line should be installed avoiding any vibrations. This is normally achieved by installing vibration dampers (compensators). In order to avoid pulsating noises, we recommend installing a sound muffler between the compressor and the condenser. Please follow the manufacturer`s instructions when installing these components.
The installation of evaporators WKE preferably allows the refrigerant to enter through the upper connection. If several evaporators of the same size are to be connected in parallel, then it must be ensured that each evaporator is supplied with even pressure both on the refrigerant side and on the heating medium side.
For an approximation of the refrigerant capacity of the overall system following proportions of the refrigerant side volume should be used as an approximation: WKC: 30%, WKE: 40%
