Capacitor fittings
Inlet pipe bringing high-pressure gas from the compressor it is necessary to enter at the top of the condenser, and the adjacent pipelines should slope in the direction of the flow so that the drops of oil and any liquid refrigerant, which will continue in the right direction, and not back to the compressor.
Drainage pipe should always be from the lowest point, but can have a short internal upstand so that any dirt, such as pipe-scale or metal chips will be taken and not taken around the circuit. Capacitors for ammonia systems can be oil trap, as a rule, in the form of the tank, and the liquid at the outlet will be above this.
Water connection to a shell-and-tube condenser should always be arranged so that the end covers can be easily removed for inspection, cleaning and repair of pipes. Heavy end covers require the use of lifting appliances and supports the highest point of the lift shall be provided for the installation to facilitate this work.
Capacitors contain under the pressure of the refrigerant and where they exceed a certain amount, they will be subject to the requirements of the Pressure Vessel Directive (PED), and EN378. Manufacturers are aware of these requirements, and proprietary products will be equipped properly.....
