If you are unboxing your new fridge or freezer you will be keen to get all packaging removed and everything installed correctly. However, when setting up, you may find that some pipes at the back have foam wrapped around them. In most cases, this is not packaging, but is insulation. Unless the user manual advises to remove, then the insulation should be left on the pipes.
Please note, the insulated pipes referred to in this article are pipes which were insulated during production. Do not attempt to insulate pipes yourself unless stated in the user manual or by the support team.
What is insulation?
Insulation is usually foam, or another similar material, that is securely wrapped around the pipe with fastening tags to keep in place. It may be around the pipe which transports refrigerant gases, but may also be located on other pipes at the back.
The role of insulated pipes
Fridges and freezers operate in a way which keeps cool air circulating inside to maintain a low temperature. There are different types of refrigeration, such as wet wall, which have different behaviours but ultimately they rely on all parts of the appliance working together. For example the refrigerant gases will need to be transported through the appliance, whilst the compressor works to regulate the temperature. So how do insulated pipes tie into this?
Insulated pipes play a background part in the operation. Having insulation around the pipes helps to maintain the temperature inside, as the insulation prevents the heat from transferring outwards. This means that it reduces the risk of the temperature dropping during any transfers in the pipes. This is also important for the pipe itself, as it means the pipe isn’t getting too warm or cold, which could negatively impact the performance of this component.
Reasons and Benefits of insulated pipes
With pipes being insulated, they can provide better energy efficiency as essentially it prevents potential heat loss. This means the appliance can be more energy and cost effective for a user as the appliance is able to maintain and regulate the correct temperature.
Insulated pipes also work to minimise the wear and tear of parts. This is because if water sits on the pipe over time, it can begin to corrode. This means that the pipes can theoretically last longer than they would without insulation.
The insulation may also be in place to ensure user comfort, by covering pipes which may get warmer and cause discomfort if touched. This means that if you do need to visit the back of the appliance, the insulation can protect you and the pipes.
Insulated pipes are an important part to some fridge and freezers and help to maintain normal operation. Remember to only remove the packaging if stated, and if you are unsure to contact the relevant support team for confirmation.
