Refrigerant systems should be carefully installed so that they are efficient and do not suffer from any kind of adverse and dangerous issues. Refrigeration systems are widely popular and are used in residential, commercial and industrial settings for various purposes.
The reputed HVAC equipment and PPR pipes fittings suppliers in UAE can provide you high-quality refrigeration units that are reliable and efficient. The refrigeration system installer should follow the below-given tips, so that the system is installed in a secure, easy to maintain and reliable way.
Location of The Main Components
The main components of the refrigeration unit, including the condenser, compressor and evaporator should be mounted in the most secure manner. The installation should be in accordance with the instructions provided by the manufacturer, and the accompanying brackets should be used precisely and perfectly.
Refrigeration System Installation
The refrigeration system components should be installed in a very quick manner so that least of time is taken. If there is more than the usual time taken during the installation process, then air, moisture, and impurities can collect with the different components of the system.
When the system if fully evacuated and charged, then you can install the filter driers and the compressors. The refrigeration system may have different kinds of openings. They should be sealed so that no water vapor or air can penetrate inside them. The installation process may have different kinds of pauses, and the air and moisture may infiltrate the refrigeration system during the time lags.
Installation of The Pipes Fittings
All pipe fittings that are used should be installed in a vertical or horizontal way. Discharge lines and suction lines are the 2 exceptions, and these can have slight falls away from or towards the compressor, respectively. The clips, brackets and other fixings related to the pipes should be pitched in a way so that they can well-suit the diameter of the pipe. If the compressor has been fitted with the vibration dampers, then the vibration eliminators should also be fitted for the discharge and the suction piping.
Oil Locks
Vertical-suction lines should be mounted with the oil locks, and the pitch here can vary from 4 to a greater of 5 meters. Some systems that have the larger load variations should have the double-risers.
Location of The Other Components of The Refrigeration Unit
All refrigeration unit components should be precisely installed so that this quality equipment can be easily accessed for the repair and maintenance services. The locations of the safety and control equipment should also be figured in a way so that they can provide for prompt adjustment and testing, by the use of the ordinary kind of tools.
Compressors
If the system has the parallel compressors, then they should have the oil equalization features. Otherwise, the compressor which runs more will get oil from the other less running compressor. Equalizing tube, which has been installed between the oil sumps, can provide for oil equalization. Oil-level regulators can also be sued for oil equalization.
Storage Conditions of The Components
All the components of the system should have a temperature equal to, or greater than the surroundings when they are opened. Condensation may adversely affect the components if the temperature is low. For instance, components and equipment that are brought directly from the cold-service van may have a low temperature. The components should only be opened after some time, in these conditions.
Cutting OF Pipes
Pipes should only be cut by using a saw or a cutter. Refrigerants and lubricants should not be used for the purpose. A deburring tool can be used for removing the external and internal burrs.
Cleaning of Pipes
Dry nitrogen or dry and compressed air can be used for cleaning the pipes. The air has to be blown at the high blast. Ordinary and room air should not be compressed and used for cleaning the pipes, as it has lots of moisture.
Soldering
Different kinds of soldering processes can be sued. While phosphor solders can join copper-to-copper joints, the silver solders can join the non-oxidized and clean metal surfaces. Solders should be used economically. Use of more-than-require solder may cause blocking of the system pipes in a partial or a complete way.
Temperature
The temperature should always be within limits. When the melting temperature is attained, then the flame should be drawn backward in a slow manner. Hot-water brushing will remove the external residue of flux. Lead or tin based alloys should not be used for the soldering of refrigerant systems.
