Method for determining shutoff valve and refrigerant leakage sensor interlinking for an air-conditioning system

Abstract

The current invention relates to a Method for determining shutoff valve and refrigerant leakage sensor interlinking for an air-conditioning system. The method comprises the steps of preparing a floorplan of a building with multiple rooms, mapping indoor units of the air-conditioning system and shutoff valves on the floorplan, mapping pipes between the shutoff valves and the indoor units on the floorplan, identifying each room having at least one indoor unit and/or refrigerant carrying piping, identifying each refrigerant leakage sensor installed in each room having at least one indoor unit and/or refrigerant carrying piping. This information is then used to determine correspondence relationships between each refrigerant leakage sensor and each room, between each valve and each pipe and between each pipe and each room through which said pipe passes and/or enters. These three types of correspondence relationships are used to determine a fourth correspondence relationship each between shutoff valve and each refrigerant leakage sensor.
