HVAC compressors are designed to operate at maximum efficiency. Although some are organically more efficient than others simply due to how they are constructed, it's up to you to make sure they remain in good operating order at all times. Compressors draw a large amount of power because of the work they do. To maximize their efficiency, it's essential that they are serviced regularly and that qualified HVAC technicians be called in to handle any problems that may arise.
There are some things that we all take for granted, and at work, one of those is the HVAC system. When it’s cold we expect the heating to work, and when it’s warm, we turn up the air conditioner. When something stops working, it is usually when we need it most, and then it becomes a company crisis as the search for someone who can fix things at this very moment is in dire need.
Nobody likes to find insects or rodents, especially cockroaches in or around their commercial refrigerant system. Let alone these insects and other pests that enter the food storage spaces like pantries and refrigerators or your commercial establishment. Getting rid of them can become a serious issue if the place is fully infested by insects or rodents. They can find a million nooks and crannies to hide comfortably and start raving havoc on your commercial refrigerant system.
CPR valves play an important role in protecting your refrigeration equipment. If you are not familiar with CPR valves and how they work with your commercial compressor, this guide will help you understand more about this component. It is important to note that not all systems use a CPR valve, so you may have to inspect your system to determine whether or not this component is in place.
One question that you will often hear with regard to commercial compressors is how much oil pressure they need to operate. The oil pressure required will depend on the size, type and intended use of the system. The age of your compressor may also affect oil pressure, because older compressors have more worn parts, which creates gaps that allow for extra oil to flow, thereby reducing pressure in the system. As you compare different compressor types and oil pressure requirements, it is important to understand the difference between useful or net oil pressure and discharge oil pressure. These two measurements apply to different parts of your system, and you must understand which is which to ensure that your compressor is properly lubricated and operating normally.
Bearings are designed to help the internal components of your compressor glide smoothly around one another without binding. Unfortunately, bearings are a wearable part, and as they get worn down there are gaps in their path which can cause vibration. Knowing the common signs of vibration and bearing wear is a good way to plan for replacements before something goes wrong.
Commercial compressor electronics are, in many cases, the key to a properly managed HVAC system in any building. These special electronics serve as the brain of your system, allowing you to control how and when your system operates and giving you feedback about performance so you can make more informed decisions about your business.
When assessing the efficiency of an HVAC/R system, all operating expenses should be considered, including the cost of energy consumption, maintenance, repairs, and eventually equipment replacement. Although a variety of factors can affect the efficiency of HVAC and refrigeration systems, the compressor plays a major role in the overall performance of these systems. The consequences of using an underperforming compressor can be multi-faceted and damaging to your company’s bottom line. By reading the rest of this post, you’ll find out how an inefficient compressor can decrease your profit margin.
A conventional compressor operates more efficiently if the pressure trapped inside the cylinder head assembly and/or discharge line is released after each cycle. As pressure adds load to the compressor start-up process, finding a way to release it will result in smoother compressor start-ups and a lower starting torque of the motor. These translate into maximum operational reliability, increased system efficiency, and less wear and tear on components.
Heat is a normal consequence of the compression process. However, a compressor that runs too hot is cause for concern mainly because it will need to work harder, for longer periods. Besides consuming more energy, a compressor that operates under intermittent or continuous overheating conditions may fail before its time and, more importantly, when least expected. Currently, compressor overheating is one of the most common causes of commercial refrigeration problems.
