The invention provides a refrigerant leakage detection method and device, and relates to the field of household appliances, and the method comprises the steps: obtaining an exhaust port temperature and a condenser outlet temperature, and determining an actual temperature difference according to the exhaust port temperature and the condenser outlet temperature; judging whether the consumed time when the actual temperature difference reaches the preset temperature difference threshold value exceeds a preset time threshold value or not, and judging whether the rising value of the temperature of the exhaust port in the consumed time exceeds a preset temperature rising limit value or not; if the consumption time exceeds the preset time threshold value and the rising value of the temperature of the exhaust port in the consumption time exceeds the preset temperature rising limit value, it is determined that the refrigerant of the heat pump clothes dryer leaks. The refrigerant leakage detection method provided by the
