Application Examples

Your typical air conditioning system and control sequence… Air conditioning systems are primarily on/off devices of a fixed capacity, controlled by the limits of the thermostat. A standard thermostat, when set at 72°F (with +/- 1°F range), will turn the air conditioning on at 73°F and cool the space, at… Read More

Air Conditioning isn’t about temperature control, it’s about removing humidity from the air. Dehumidification is arguably much more important in order to maintain a comfortable space! Without a properly sized air conditioning system, it’s going to be impossible to control the relative humidity in the space. Read More

A system that has the ability to modulate capacity also can provide better reliability and fewer operating problems. These often are related to stresses placed upon the system’s compressor. Short cycling, low airflow, and other system problems can easily be corrected with the APR control. As a result, the Rawal device can reduce call backs and warranty issues, even on new sys Read More

Many applications, including surgery suites, clean rooms, high-precision manufacturing, etc., have tight temperature and humidity requirements that can benefit from the addition of the APR Control. Read More

The APR Control provides (air conditioning circuit) modulation for humidity control, the benefit of extended runtimes, and the ability to maintain a system in a dehumidifying mode all serving Comfort and Indoor Air Quality. These factors allow simple single-stage/multi-stage DX systems to respond to a wide variety of operating conditions that all benefit space comfort. Read More

The introduction of outside air with highly variable load creates the need for variable-capacity systems. APR Control enables the system to match capacity with changing load conditions. Read More
