Capacity controls are valves set to modulate how often a system cools based on pressure. These controls work off the Guy-Lussac’s gas law that pressure and temperature are directly related to each other (i.e., if the temperature rises, the pressure rises; and if the temperature drops, the pressure drops). These capacity control valves can be set to introduce hotter gas from the line exiting the structure (discharge line) into the line entering the structure (the suction line) to increase pressure when the valve senses the pressure dropped too low. Because the valve exchanges between the two lines, the compressor is to varying degrees “bypassed” so that the system’s capacity is lowered to match the load (i.e., it doesn’t cool as much when it isn’t necessary). This capacity control is often termed “hot gas bypass” because of the exchange between the two lines. Rawal valves are yet another type of valve for controlling capacity and, when properly installed, is one of the better capacity controls available. is one of the only Rawal certified installers in the DFW area. Rawal valves extend the compressor’s run time, thereby yielding potential energy savings (up to 12%), less wear-and-tear, and less humidity in the building.
