    摘要： A refrigeration systems diagnoses its pressure sensors by turning the system off, determining whether the pressure sensors on the high-pressure-side and on the low-pressure-side of a refrigeration circuit detect unvarying pressures, and comparing the pressure values detected by a high pressure sensor and a low pressure sensor with each other. The high pressure sensor or the low pressure sensor is regarded as defective when the difference between the two pressures detected falls outside a tolerance range. In one embodiment an analyzer compares the pressures to produce a signal indicating failure when the pressure difference falls outside the tolerance range.
