high and low pressure compressor

How to Locate the High and Low Sides on a Home AC ,

The compressor accomplishes this task by creating high and low pressure areas with the use of a moving piston in a sealed chamber The high and low sides on a home A/C compressor are also known as its discharge and suction lin These are the pipes in which cold and hot coolant is constantly flowing into and out of the compressor
