The invention provides a control method and device for refrigeration equipment, and the method comprises the steps: determining a temperature monitoring result of an evaporator according to a first temperature of the evaporator in the refrigeration equipment, a second temperature of at least one air outlet of the refrigeration equipment, and a third temperature of an external environment; according to the temperature monitoring result of the evaporator, reference adjusting parameters of the refrigeration equipment are determined; the reference adjusting parameters comprise the current actual temperature of the evaporator and the current limit working parameters of a compressor in the refrigeration equipment, and the current actual temperature is within the preset normal working temperature range of the evaporator; and after a refrigeration request is received, the current control strategy of the compressor is determined according to the target temperature in the refrigeration request, the reference adjusting parameters of the refrigeration equipment and the temperature monitoring result of the evaporator, and the compressor is controlled to work according to the current control strategy. Therefore, according to the scheme, it can be guaranteed that when the temperature of the evaporator is abnormal, the compressor cannot be completely shut down, and therefore the reliability and user satisfaction of the air conditioning system are improved.

    本申请提供了一种制冷设备的控制方法及装置,该方法包括:根据制冷设备中蒸发器的第一温度、制冷设备至少一个出风口处的第二温度、以及外部环境的第三温度,确定蒸发器的温度监测结果;根据蒸发器的温度监测结果,确定制冷设备的参考调节参数;参考调节参数包括蒸发器的当前实际温度以及制冷设备中压缩机的当前极限工作参数,当前实际温度位于蒸发器的预设正常工作温度范围内;当接收到制冷请求后,根据制冷请求中的目标温度、制冷设备的参考调节参数以及蒸发器的温度监测结果,确定压缩机的当前控制策略,并按当前控制策略控制压缩机工作。这样,本方案可保证在蒸发器温度异常时,压缩机不会完全停机,从而提高空调系统的可靠性和用户满意度。
