Embodiment Construction
[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0019] Such as figure 1 As shown, this application proposes a defrosting control method for a refrigerating unit, which needs to detect the return air temperature, supply air temperature, low-pressure pressure, and air pressure difference between the inlet and outlet of the refrigerating unit, and comprehensively determine the difference between the return air temperature and the supply air temperature. Whether the temperature difference between the return air temperature and the supply air temperature, the low pressure pressure and the air pressure difference betw...
