When the unit is restarted, the oil temperature in the compressor 1 and the water temperature in the evaporator 5 are both in a proper temperature range, so that the unit can reach a better working state at the highest speed, and the quick starting of the unit is realized.

If a water tank is not provided in the unit, the water tank may be separately provided and communicated with both the heat conductive pipe 82 and the evaporator 5. Of course, if the unit is self-contained, the lines between the cold water outlet 52 or inlet 51 and the tank 10 will typically be routed through the indoor circuit.
Still referring to fig. 1, the solar device 8 further includes a solar photovoltaic cell (not shown), a solar controller 84 and an electricity storage unit 85, the solar photovoltaic cell is connected with the electricity storage unit 85 through the solar controller 84, and the electricity storage unit 85 is connected with the general controller 7 of the cold water air conditioning unit.
