Compressor types and what they are designed for
In this episode of "Taking the Temperature on HVAC," Jamie, John, and Jorg explore the different types of compressors offered by Danfoss, including reciprocating, scroll, screw, and Turbocor compressors. They discuss the operational differences between these compressors, such as the pulsation in reciprocating compressors versus the smooth operation of scroll compressors, and the factors influencing compressor selection, like efficiency, temperature range, and application needs. The hosts emphasize that choosing the right compressor depends on the specific system requirements, from low-temperature refrigeration to high-capacity heat pumps, providing valuable insights for HVAC professionals looking to optimize their systems.

Beyond the Setpoint: What do we control in a refrigeration system?
While the space temperature in a refrigerated space may be used to control the refrigeration system, there is a lot more going on that we must also take control of. The thermostat initiates a pump down cycle to control/limit refrigerant migration to protect the compressor and enable defrost to occur more rapidly. Control over the temperature, humidity, velocity and direction of air leaving the unit cooler must be maintained to ensure that product is not dried out or frozen even when stored in temperatures above freezing. How product is placed within the cooler or freezer must be controlled so that sufficient airflow through the space and around the product occurs for quick and efficient heat removal.
