Commercial refrigeration compressors – all you need to know
It is critical to have knowledge of the function of all the different components when the commercial refrigeration system is an integral part of your kitchen. One element stands out as the most crucial among all the other refrigeration components: the commercial compressor. This vital organ of the fridge has often been referred to as the "heart" of a commercial refrigeration system, as it performs some of the most essential technical and mechanical tasks that take place within the machine. This component works the hardest to compensate for a part's or component's loss if it starts to deteriorate or gets damaged. Similarly, the whole system will grind to a halt if the titular part of the system stops working. So, why exactly is the titular element crucial for cooling operations? We will look at the device's importance and several other facts to reveal its working process for everyone.
Apart from the titular item, one appliance that needs continuous maintenance is the Square Glass Cake Display, a crucial component of every café and food establishment. Go to the Simco website for more information on the product.
Importance of a Commercial Refrigeration Compressor
The primary task of the industrial fridge compressor is to compress the gas present in the refrigerator. No matter what kind of refrigerant you use, it must be flattened to reach an appropriate pressure. Pressurisation makes the gas available to the rest of the system, facilitating the cooling process.
- The compressor features one of the most significant considerations in any commercial refrigeration system. It is also essential for industrial HVAC setups. This appliance is responsible for performing both the cooling and the heating function in a commercial HVAC– both surprisingly similar from an engineering perspective.
- Although the same companies usually make them, the hardware in commercial refrigerators varies significantly from those used in the HVAC procedure. Each compressor is created for specific tolerances that work under a particular demand and environment within a given system.
- Once the suitable commercial compressor has been selected, care and maintenance are ongoing concerns for the system's life. Providing an ideal upkeep routine helps ensure you can get years of reliable work from your commercial machine.
- Today's models last longer and provide more efficient service throughout their working life. However, it doesn't mean that the maintenance is dispensable. Similarly, an operations manager in any segment should have a strategy to replace the item when age leads to reduced performance.
Types of Compressors
Piston Compressors
One of the most common options in the market is piston refrigeration compressors. You can find these items in all configurations, whether open, hermetic or semi-hermetic. In addition, these products are also available for all power levels, starting from the lowest to the highest capacity. You have to lubricate the piston commercial fridges’ offerings constantly. In addition, ensure proper care as it is susceptible to the presence of liquid at the inlet, which can cause damage to the valves. Piston refrigeration variations are more effective and cost-efficient than other alternatives, but their technology is also considered the least strong.
Spiral Refrigeration Compressor
Spiral compressors, also known by the name scroll devices, are designed with the help of twin rollers of spiral dimensions. One of the spirals is permanent, while the other traces an eccentric orbital movement without rotation that moves the refrigerant to the centre of the spiral while reducing its volume. The primary benefit of these variations is the lower number of parts than piston cooling models, resulting in significantly more output. This type of product imposes more minor torque variations on its engine, enhancing its trustworthiness. Additionally, it is also less sensitive to the presence of liquid in the inlet.
It is limited in power (40-50kW), but you can combine several appliances in parallel to obtain a higher power level, reaching up to 300-400kW. Spiral fridge hardware makes less sound compared to the piston variants, and they are utilised in multiple air conditioning systems and the latest models. You can check out our latest models on Simco – the leading commercial refrigeration supplier, manufacturer and distributor in Sydney & Melbourne.
Screw Variant
In a screw refrigeration compressor, the refrigerant is flattened by a helical screw rotating at high speed. You can find a couple of configurations here - single-screw and twin-screw variants. These cooling options provide excellent output, and you can get around 20 to 1,200kW power range from them. These products also have fantastic product life and are highly trustworthy. Still, you must lubricate them correctly to ensure the sealing between the moving components, reduce noise, and cool down the refrigerant. You can also note some disadvantages that screw refrigeration offerings cost significantly more and acquire additional space compared to piston cooling variants.
One product where you will find the best quality product is Solid Door Cooling/Freezer Tables, which boasts a fan-forced cooling procedure and easily accessible defrost functionality. Visit the website of Simco for more clarity.
Points to Know about the Fridge Compressor
Don’t Blame your Compressor for Every Issue Plaguing your Refrigerator
In the old times, the traditional reciprocating items used to suffer a lot of deterioration and damage due to their pistons constantly working all day. Therefore, the mindset of double-checking the said component when in doubt about the performance of commercial freezers exists now. However, today’s modern offerings are much more trustworthy, and it is wrong to assume that most issues generate in this component. The first thing to evaluate while checking a refrigeration system issue is usually the most straightforward and easiest to ignore - the presence of adequate refrigerant. Start from this point and thoroughly review any complicated electronic components, which may become imprecise as internal elements suffer from deterioration.
Investing in a Larger Product Doesn’t Necessarily Guarantee Better Results.
One of the most efficient methods to prolong your refrigerator’s life and save significant capital on its electricity expenses is to size your equipment precisely for your system. If you buy a bigger fridge unit than you require in your kitchen, it will result in a waste of resources. Partial load management can assist you in capturing considerable ongoing savings for more significant variants. If you are changing the equipment, it is always recommended to get a similar variant from the same manufacturer you dealt with previously. You should consider replacing your product only if there has been an enhancement in demand on your system.
It is Not Mandatory to Spend Big on Changing the Compressor
One of the inevitable facts of life for any organisation that depends on its refrigeration systems is item replacement. You need to evaluate the duration up to which your product is going to serve you effectively. Once the item reaches the end of its working life, you must have a contingency plan in place. This practice will help save significant money, time and additional hard work. Many people start searching for a replacement at OEM-affiliated sellers. Unfortunately, this step mostly means paying a considerable sum for a redesigned offering carrying a brand tag that offers no real benefit regarding quality. A remanufactured industrial appliance will perform equally well and comes to you at a significant discount. You can get a good deal on Simco – the renowned commercial refrigeration supplier and manufacturer in Melbourne & Sydney.
One such piece of equipment with low expenses is the Top-Mounted Solid Door Freezers, in which the food items can be kept at precise temperatures due to the premium unit on top. Visit Simco's official webpage to purchase the product.
