Two Compressors in One

In high-ambient environments, whether ongoing or during peak demand seasons, Carlyle Compound Cooling compressors offer serious performance advantages over single-stage compressors. Unlike single-stage compressors, Carlyle Compound Cooling uses an economizer cycle to deliver higher capacities and efficiencies for the same displacement. The first stage utilizes four cylinders and always operates at a low compression ratio. Two additional cylinders act as the high stage, completing the compression cycle at discharge temperatures much lower than a single-stage compressor. Lower discharge temperatures result in increased reliability.

The result is two complete cycles operating at low compression ratios. That means lower internal losses and higher efficiencies than single-stage units of the same size. And since each unit operates at such a steady capacity, your systems will cycle on and off reliably, not repeatedly.

Easy to Install, Easier to Keep Up and Running

With 7 models to choose from, Carlyle Compound Cooling was designed to fit with virtually any low temperature application. Unit dimensions are similar to other Carlyle compressors, so it'll fit easily into an existing system specification. Installation is as easy as bolting the unit into place, attaching the economizer, and making the usual suction and discharge connections. Issues that were seen early on in the compressor's life have been resolved through adherence to recommended application specs, and today more than 10,000 R-22, R-404A and R-507 Compound Cooling compressors are operating in the field.

Preventing Refrigeration Line Vibration Problems

Refrigerant leaks have always been a major concern in any air-conditioning or refrigeration system. Costs associated with refrigerant replacement and the reliability of the unit gives system designers and manufacturers the incentive to keep refrigerant losses to a minimum.

Causes of vibration in discharge lines can be separated into the following three primary categories: 1) structural resonances; 2) forced vibration; and 3) acoustical resonances. Of the causes of vibration, structural resonances are the most common, followed by forced vibration and acoustical resonances. Multiple combinations of the three also can cause vibration.
