本发明的冷藏冷冻装置将加热单元的发热器件设置在压机室内，并在压缩机和加热单元均处于工作状态的情况下，使第一风扇根据压缩机的表面温度启动或停止，不仅无需在箱体的其他位置开设容置槽，降低了箱体的生产成本，利用压机室的大空间提高了发热器件的散热效率，而且有利于防止压机室过热，保证发热器件的使用寿命，降低压缩机的工作负荷。
进一步地，本发明在压缩机处于工作状态且加热单元处于非工作状态的情况下使第一风扇保持开启、第二风扇根据压缩机的表面温度启动或停止，在加热单元处于工作状态且压缩机处于非工作状态的情况下使第二风扇保持开启、第一风扇根据加热单元的发热器件的温升速率启动或停止，在保证散热效率的同时，避免了第一风扇或第二风扇频繁启动，延长了风扇的使用寿命并降低了风扇噪音。
进一步地，本发明将第一风扇设置于压缩机远离发热器件的一侧，第二风扇设置于发热器件远离压缩机的一侧，并使空气由压缩机流向发热器件，克服了现有技术中将加热单元的发热器件尽可能地远离其他器件、或使低温空气首先流过加热单元的发热器件再流向其他器件的技术偏见，降低了对压机室原有器件的影响，基本不需要改变压机室原有器件的布局，降低了生产成本。
