When, the shut-off valve being arranged on the condensate water discharging channel is closed, second valve 600 is opened and condensed water is added into cooling
In tower 200.After condensed water supplements, second valve 600 is closed.The aperture of second valve 600 and the cold water
The cooling capacity of unit 300 is related, and the cooling capacity of water cooler 300 changes with the refrigeration duty of indoor needs and changed, and when actual motion should
Cooling capacity constantly changes, cooling capacity=(1.1-1.2) × building cooling load of water cooler 300.Building cooling load is set in engineering
Timing is calculated frequently with estimation algorithm：Building cooling load=construction area × unit area refrigeration duty.When the water cooler 300 is transported
For row at bad working environments (i.e. cooling capacity increase), 600 aperture of the second valve increases △ F2；When unit operates in non-bad working environments
When (i.e. cooling capacity is reduced, such as conditioning in Transition Season), the aperture of second valve 600 reduces △ F2.Increase △ F2I.e. cooling tower needs
Rate of water make-up increases (remarks：△F2More than to indicate numerical values recited, also comprising positive and negative, increase is positive, and reduction is negative).By adjusting
The aperture of two valves 600 changes the rate of water make-up of cooling tower 200, maintains the water flow of cooling tower 200 constant.

Second recovery approach 132 is connected between 600 and the heat exchanger 400.First valve 700 is arranged in the tap water
On moisturizing channel 510.Change tap water increment by adjusting the aperture of the first valve 700, reduces tap water using condensed water
Consumption.Specifically, the refill flow of cooling tower is：G=0.015 × 3.6Q/c (t1-t2), wherein：Q is the cooling of cooling tower
Heat, unit kW, generally the 1.3 of water cooler cooling capacity times；C is the specific heat of water, and unit is kJ/ (kg ﹒ DEG C)；t1For cooling
Water inflow temperature, unit are DEG C；t2For cooling water leaving water temperature, unit is DEG C；For determining cooling tower (t1-t2) it is fixed
Amount, this fixed amount and water cooler have relationship, its specified cooling heat is definite value for determining cooling tower.But it is right
For entire air-conditioning system, the cooling heat of cooling tower is to change with the cooling capacity of water cooler and change.So cooling tower
Rate of water make-up it is not only related with cooling range, it is also related with water cooler cooling capacity.The aperture of first valve 700 is according to cooling tower
Rate of water make-up G and condensation water quantity G1Difference control, if the initial opening of the first valve 700 be △ F：△ G=G-G1=△ F* α,
Middle α is fixed numbers, and the numerical value is related with attribute of valve itself.As cooling tower rate of water make-up G and condensation water quantity G1Difference △ G1
It is greater than the set value △ G, illustrates that the tap water increment needed is bigger than setting value, then increases the aperture △ F of the first valve 7001；When
Cooling tower rate of water make-up G and condensation water quantity G1Difference △ G1Equal to setting value △ G, illustrate the tap water increment needed than setting
Be worth it is close, then the first valve 700 aperture maintain initial opening it is constant；As cooling tower rate of water make-up G and condensation water quantity G1Difference
△G1Less than setting value △ G, illustrates that the tap water increment needed is smaller than setting value, then reduce the aperture △ F of the first valve 7001
(remarks：△F1It is more than to indicate numerical values recited, also comprising positive and negative：Increase is positive, and reduction is negative).By controlling first valve
700 aperture controls the make-up flow size of tap water and the supply total amount of tap water.
