A method of inspecting a leak detection system in a short time is disclosed. The leak detection system includes a leak detection line, an on-off valve, a flow mater, an operation controller configured to detect a fluid leak from a fluid line based on a first flow rate measured by the flow mater, a drain line, and a drain valve attached to the drain line. The inspection method includes: opening the on-off valve and the drain valve, with a supply valve and a return valve closed; measuring a second flow rate of fluid in the leak detection line by the flow mater; and determining that the leak detection system has a defect when the second flow rate is lower than a predetermined reference value.

A system configured to detect failure of a hose includes a sensor assembly having a body with a first arm and a second arm pivotally coupled to one another at respective first ends, and the body is configured to move between a closed position and an open position. The sensor assembly also includes a first electrical contact positioned at a respective second end of the first arm and a second electrical contact position at a respective second end of the second arm. The first electrical contact and the second electrical contact are configured to contact one another to form a complete electrical circuit when the body is in the closed position and are configured to be separated from one another to form an open electrical circuit when the body is in the open position to facilitate detection of the failure of the hose.

A refrigerant leak sensor includes: a first refrigerant sensor element configured to, when powered: measure a first amount of the refrigerant present in air; and generate a first output based on the first amount; a second refrigerant sensor element configured to, when powered: measure a second amount of the refrigerant present in air; and generate a second output based on the second amount; a first selection module configured to: during a first period, apply power the first refrigerant sensor element and not apply power to the second refrigerant sensor element; and during a second period after the first period, apply power to the second refrigerant sensor element and not apply power to the first refrigerant sensor element.
