Importance of Cleaning Air Cooled Condensers on All Refrigeration systems

There is an important need for regular maintenance of some refrigeration components, especially the cleaning of the air-cooled condenser. Failure to keep the condenser clean will result in abnormal operating temperatures and system pressure resulting in compressor failure and extremely high service repair costs which can be avoided with preventative maintenance checks.

For a refrigerator, it is important to keep the condenser clean, just as it is important to keep the water level up in the radiator of a car. Most manufacturers recommend at regular intervals, not exceeding six months, and more frequently in dusty areas, bakeries, fish and chip shops, commercial kitchens etc. to remove the grill that is placed in front of the condenser- the condenser being a metal finished assembly having a copper tube running through the fins, and similar in appearance to the car radiator. Ensure that there is adequate fresh air flow into the condenser and the hot exhaust air can escape freely without recirculation.

Dust usually forms a coating over the condenser, which may be removed by brushing or vacuum cleaner. Sometimes this dust collects within the fins and must be removed. If using a brush always brush parallel to the aluminum fins and never across as this will bend the thin aluminum material and reduce air flow through the condenser. If the condenser is blocked with oil you will need to switch the system off and use a suitable degreaser for cleaning. This can be a very messy procedure but must be done thoroughly in order to maximize system performance and extend the useful life of the compressor.

A vacuum cleaner will usually pull dust out provided the condenser has not become thoroughly clogged. If this occurs, it may be necessary to use a high-pressure gas to blow this dust out.

After cleaning, always check to see that the condenser is clean right through the fins, a torch usually being needed to ascertain this. Refit the grill in the front of the condenser when cleaning is completed.

Some small low temperature cabinets (chest freezers) do not have a finned condenser, but a plate, or wire type of condenser, similar to those used on household refrigerators, or alternatively; have the outer skin of the refrigerator as a condenser. This is usually evident by a slightly warmer outer cabinet temperature than that of the surrounding objects. Some new systems are fitted with "reversing" condenser fan motors that can reduce the frequency of having to clean condensers.

Note: Some new quality systems are fitted as standard with an overheat temperature sensor that will switch off the compressor to protect it from damage due to overheating.

Cold Storage Container

You have probably heard of storage containers before, they are becoming an increasingly popular method of industrial storage. They come in many different sizes and can be used for a wide range of applications. A slightly different type is the Cold Storage Container.

Cold Storage Containers are refrigerated with variable temperature controls; they are usually capable of temperatures ranging between -15 degrees to 75 degrees (Fahrenheit). They are quite versatile and can be placed outside or inside at docking height or on the ground. They provide refrigeration that is environmentally friendly (ozone safe).

The larger size containers usually have strong hard wearing floor, this floor is capable of withstanding the weight of forklift trucks which makes them great for industrial uses.

Due to their refrigerating properties Cold Store Units are most suited for applications and industries including fast food chains, pharmaceutical manufacturers, supermarkets, caterers and food processors.

Not only are the containers available as free standing units but cold stores can also be available as trailers, the trailers are extremely portable and can be placed almost anywhere. They come with a tow bar attached and due to their mobility can be towed by pretty much any vehicle with a tow bar. (You do not need a powerful van or truck to transport these units.)

These containers are available for purchase however due to the reasons for using them and the fact they are more than often on a short term basis, a lot of companies offer these out for hire and that seems to be the most popular choice.

Breakfast is Dinner?

Did you know that the word “dinner” used to mean “breakfast”.

The English word “dinner” comes from a French word “disnar”, which means “breakfast.”  Traditionally, dinner (meaning ‘breakfast’) was the first meal of the day, eaten around noon.  It also happened to be the biggest meal of the day, with a lighter meal coming later known as supper.  Eventually, more meals started being added to the day with people eating meals before large noon meal of dinner.  Rather than calling these earlier meals that broke the fast by the word that means breakfast (dinner), the name “dinner” now stuck as meaning the largest meal of the day.  As time has passed, in most cultures that use these words to describe their meals, the largest meal of the day gradually got moved later and later in the day until its meal time was around the time we used to have supper (which used to be a light meal).
