Abstract: An air conditioning system includes an indoor unit, an outdoor unit, a first expansion valve, a second expansion valve and a controller. The controller is configured to: control the air conditioning system to be switched to a cooling mode, control an indoor expansion valve and the second expansion valve to be closed and control the first expansion valve to be opened when a refrigerant leakage occurring indoors is obtained; control a compressor to be stopped and the first expansion valve to be closed, if the compressor satisfies a first preset condition; control the compressor to be started and the first expansion valve and the indoor expansion valve to be opened, if the refrigerant leakage continues indoors after controlling the compressor to be stopped; and control the compressor to be stopped and the first expansion valve to be closed, if the compressor again satisfies the first preset condition.

Abstract: An instrument and method for mechanical properties in situ testing of materials under a high temperature and complex mechanical loads are provided. The instrument includes: a support frame module used to provide a stable support and an effective vibration isolation for each functional module of the instrument; a high-frequency fatigue load applying module used to apply a high-frequency fatigue load on a tested sample; a static-dynamic mechanical load applying module used to apply a combination of static-dynamic tension/compression/bending loads on the tested sample; a high/low temperature applying module used to apply a variable temperature environment from a low temperature to a high temperature on the tested sample; and an in-situ monitoring module that may integrate a surface deformation damage measurement assembly, a three-dimensional strain measurement assembly, a microstructure measurement assembly, and an internal damage detection assembly according to a practical testing requirement.
