Test for the automated detection of leaks between high and low pressure sides of a refrigeration system

A method for testing a refrigeration system having a high pressure side, a low pressure side, and a first and second high-to-low side valves;

• said method comprising the steps of:
• (a) closing said first and second high-to-low side valves;
• (b) decreasing a pressure of said low pressure side and increasing a pressure of said high pressure side;
• (c) opening said first high-to-low side valve, and monitoring for changes in pressure in said refrigeration system to verify opening operation of said first high-to-low side valve;
• (d) re-closing said first high-to-low side valve;
• (e) decreasing a pressure of said low pressure side and increasing a pressure of said high pressure side;
• and
• (f) opening said second high-to-low side valve, and monitoring for changes in pressure in said refrigeration system to verify opening operation of said second high-to-low side valve;
• (g) re-closing said second high-to-low side valve;
• (h) decreasing a pressure of said low pressure side and increasing a pressure of said high pressure side;
• and
• (i) determining if leaks are present between said high and low pressure sides by monitoring for changes in pressure in said refrigeration system.
