摘要： A refrigeration cycle apparatus includes an air conditioner, sensors, and processing circuitry. The processing circuitry determines a predicted opening of the electronic expansion valve of the air conditioner based on outputs of the sensors and an operation frequency of the compressor, assuming normal operation of the air conditioner. The processing circuitry calculates a prediction error by subtracting a measured opening of the electronic expansion valve from the predicted opening. The processing circuitry calculates multiple prediction errors in advance, calculates an offset value as an average of the multiple prediction error, and outputs a corrected prediction error by subtracting the offset value from the current prediction error. The processing circuitry detects a refrigerant leak of the air conditioner based on the corrected prediction error.

摘要： According to one embodiment, a refrigeration cycle apparatus, a fusible plug is attached to a low-pressure-side pipe between an evaporator and a compressor. The refrigeration cycle apparatus includes a heat quantity reduction member. The fusible plug fuses when a temperature of heat transmitted from the low-pressure-side pipe to the fusible plug reaches a predetermined value or more, and then opens the inside of the low-pressure-side pipe to atmosphere. The heat quantity reduction member reduces the quantity of heat to be transmitted to the fusible plug.
