The invention provides a parking air conditioner and a refrigerant leakage detection method thereof.The refrigerant leakage detection method comprises the steps that a first temperature difference is determined, the first temperature difference is the difference value of a first sub-temperature difference and a second sub-temperature difference, the first sub-temperature difference is the temperature difference of the inner environment temperature at the first moment and the inner pipe temperature of an evaporator, and the second sub-temperature difference is the temperature difference of the inner pipe temperature of the evaporator at the second moment; the second sub-temperature difference is the temperature difference between the inner environment temperature at the second moment and the inner pipe temperature of the evaporator; determining a second temperature difference, wherein the second temperature difference is a difference value between the temperature of the electric device at the first moment and the temperature of the electric device at the second moment; and when at least one of the first temperature difference and the second temperature difference meets a first preset condition, whether a refrigerant of the parking air conditioner leaks or not is determined according to the exhaust temperature of the compressor. By means of the refrigerant leakage detection method, whether the refrigerant leaks or not is accurately detected.

    本发明提供了一种驻车空调的冷媒泄漏检测方法及驻车空调,冷媒泄漏检测方法包括:确定第一温度差,第一温度差为第一子温度差和第二子温度差的差值,第一子温度差为第一时刻的内环境温度和蒸发器的内管温度的温度差,第二子温度差为第二时刻的内环境温度和蒸发器的内管温度的温度差;确定第二温度差,第二温度差为第一时刻的电器件的温度和第二时刻的电器件的温度的差值;当第一温度差和第二温度差中的至少之一满足第一预设条件时,根据压缩机的排气温度确定驻车空调的冷媒是否发生泄漏。通过本申请的冷媒泄漏检测方法以比较准确地检测冷媒是否泄漏。
