Containing differential thermal calculation module, that is, it is the temperature that temperature sensor 6 measures to calculate Δ t=t2-t1, t2, and t1=10 DEG C is setting value,
Supply water water temperature.Again because of equipment quantity of heat production Q and being proportionate property of Δ t, therefore when Q increases, Δ t increases, when Q reduces, Δ t also with
Reduction.When Δ t >=7 DEG C are calculated in computing module, illustrate that the cold provided is inadequate, control unit 8, which is adjusted, at this time increases
Solenoid valve valve opening increases cold input.When Δ t≤3 DEG C are calculated in computing module, illustrate that the cold provided is superfluous,
The adjusting of control unit 8 at this time turns down solenoid valve valve opening, reduces cold input to save cold consumption.When Δ t is between 4~6
DEG C when (5 DEG C ± 1 DEG C) solenoid valve valve opening remain unchanged.Therefore either in summer or transition season, as long as cold accumulation air-conditioner
System works, and control mechanism is also run therewith.
