Refrigeration has been accomplished in a variety of ways over the course of history, but vapor-compression refrigeration systems (VCRS) have become the preferred option thanks to their efficiency and reliability. If you've ever driven a car or used an HVAC system, you have probably used a VCRS without even realizing it. So what is a vapor-compression refrigeration system?
Compressor floodback is a common cause of HVAC/R system failure. Floodback occurs when uncontrolled liquid refrigerant enters the compressor during system operation. In an HVAC/R system, the refrigerant exits the evaporator and enters the compressor in a vapor state. But when the refrigerant is not vaporized entirely in the evaporator, a part of it gets sucked into the compressor in its liquid form. Compressor floodback may be misdiagnosed as compressor failure, even though the compressor doesn’t cause this phenomenon.
Labs are common in different industry sectors, including scientific research and manufacturing. However, strict temperature and humidity control is required particularly in medical and pharmaceutical laboratories. A lab’s environment together with storage and testing areas need to be maintained at certain temperature and humidity levels in order to ensure the safety and quality of different samples and lab products.
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.
When it comes to commercial compressors, an undercharge or overcharge of refrigerant may have many undesirable consequences. That’s because both conditions prevent the compressor from operating at peak performance, eventually leaving you with a malfunctioning system that can negatively affect your business.
Troubleshooting undercharge and overcharge conditions for commercial compressors requires a thorough knowledge of HVAC/R systems and their functions. However, the ability to correctly identify the symptoms of an undercharged or overcharged system is key to determining and fixing the exact cause of system malfunction before it escalates into a more serious problem.
Copeland's 3D series of compressors has been one of the most successful commercial refrigeration products ever released. These powerful compressors delivered a ton of flexibility and utility to the user, while also coming with an industry leading warranty program that kept them in play for many years. Today, we still see exceptional levels of demand for Copeland 3D series compressors on the remanufactured side of things. Here's why our remanufactured Copeland 3D compressors continue to set the pace for the entire commercial refrigeration industry.
York Compressors are among the top selling compressor brands available today. While they are not as well known as some of their competitors, they have built a solid brand reputation over the years, and they continue to expand their product line in new ways. Here are a few of the reasons that York compressors are selling better than ever before.
Bad compressor valves have plagued HVAC systems for ages. As with any moving part, valves wear down over time, allowing refrigerant to push past the seals and throw the system off balance. Often this leads to flooding and other conditions that cause the compressor to function less efficiently than it should. However, it can be very difficult to diagnose this issue from the outside because there are no visible indications that the compressor is suffering. That's why you need to call in an experienced technician who can solve the problem, right down to the compressor core.
Many buyers want to know where remanufactured compressors come from. There is obvious concern that some remanufactured compressors have suffered more abuse than others or that companies could be pulling old compressors out of the junk pile and trying to pass them off as almost new. To put your mind at ease, here is a quick breakdown of where we source our compressors before we begin the remanufacturing process.
When it comes to commercial HVAC and refrigeration system, the compressors play a critical role. Commercial compressors come in a wide variety of styles and sizes to fit any budget, design, and application. If you're new to shopping for compressors, you will want to have a firm understanding of how compressors are categorized before you buy. Here are five types of compressors that you will see online:
