If the determined preset temperature range is the first temperature range and the preset time range is the first time range 30 < t less than or equal to 60, the unit control parameter is that the compressor stops running and the inner fan runs at the highest rotating speed. In addition, if the determined predetermined temperature range is the first temperature range, the unit control parameter is maintained in the last state in a different predetermined time range (that is, other predetermined time range greater than 60) higher than the first time range 30 < t.ltoreq.60, wherein the unit control parameter of the refrigerating equipment is maintained in the last state to perform refrigeration control on the system component.

In this embodiment, for example, as shown in the following table, in one example, the predetermined temperature range includes a second temperature range of-2 < T.ltoreq.1, and the first temperature range is the smallest predetermined temperature range. The predetermined time ranges include a first time range 30 < t.ltoreq.60, a second time range 60 < t.ltoreq.90, a third time range 90 < t.ltoreq.120, a fourth time range 120 < t.ltoreq.ti, and a fifth time range.
If the determined preset temperature range is a second temperature range and the preset time range is a first time range 30 < t less than or equal to 60, the unit control parameter is the lowest frequency of the compressor frequency operation drive, and the second temperature range is higher than the first temperature range.
If the determined preset temperature range is a second temperature range and the preset time range is a second time range 60 < t less than or equal to 90, the unit control parameter is the minimum rotation speed of the outer fan, the throttle expansion valve is adjusted to be an oil return valve step, and the second time range is higher than the first time range.
