Fig. 1 is that this utility model embodiment is based on prediction central air conditioner system optimal downtime and the energy conserving system of analysis
Theory diagram, as it is shown in figure 1, this utility model embodiment provides a kind of central air-conditioning energy-saving system, including: chilled water circulates
System 1, cooling water recirculation system 2 and controller 3, described cooling water circulation 2 systems include cooling tower 21, cold 22, cooling
Water pump 23, described chilled water blood circulation 1 includes the cold 22 in cooling water recirculation system 2 and chilled water pump 10.
The return pipe of the cold 22 in described chilled water blood circulation 1 is provided with and is respectively used to measure return water temperature value, stream
The return water temperature sensor 12 of value and effusion meter 11, the feed pipe of cold 22 is provided with the confession for measuring supply water temperature value
Water temperature sensor 13, controller 3 connects back to water temperature sensor 12, effusion meter 11 and supply water temperature sensor 13 respectively；
Controller 3 closes in advance according to return water temperature value, flow value, supply water temperature value setting cold 22, cooling tower 21, cooling water pump 23
Machine.
That is, it is only necessary to setting the final downtime of an air conditioning system in controller 3, controller 3 is at this
Gather return water temperature value, flow value and supply water temperature value before downtime, then calculate system institute chilling requirement load, system
Pipeline residue cold also controls central air-conditioning and shifts to an earlier date the unused time, and the most remaining chilled water pump 10 works on, and is remained by system pipeline
After waste cold amount makes to be finished, chilled water pump 10 shuts down again, is so made full use of by central air conditioner system pipeline residue cold and reaches joint
The purpose of energy, is generally the quitting time of the staff of civilian mansion such as office building final downtime of air conditioning system.
Cold 22 is the ingredient having of cooling water recirculation system 2 and chilled water blood circulation 1, and cold 22 carries out two
Plant the heat transmission of blood circulation.When being embodied as, it is preferable that as it is shown in figure 1, cold 22 has multiple stage, return pipe is divided into back
Supply mains 220 and backwater are in charge of 221, and backwater is in charge of 220 one end and is connected the other end with cold 22 and connect with return main 5220,
Described return water temperature sensor 11, effusion meter 12 are installed on return main 220.The water supply of cold 22 in chilled water blood circulation 1
Pipe is divided into water main 100 and water supply to be in charge of 101, and the water supply of every cold 22 is in charge of one end of 101 and is connected with water main 100
Connecing, water supply is in charge of 101 other ends and is connected with cold 22, and described chilled water pump 10 is connected in series with between cold 22 and water main 100,
Described supply water temperature sensor 13 is installed on water main 100.
In Fig. 1, cold 22 has three, and the backwater of every cold 22 is in charge of 221 and is connected with return main 220, needs explanation
, the quantity of cold 22 can specifically adjust according to practical matter, and particular number does not limits, such as: arranges 6,8,12 etc.,
Accordingly, the quantity of the corresponding chilled water pump 10 connected of cold 22 also can adjust.
Further, the cooling tower 21 of described cooling water recirculation system 2 has multiple stage, and cooling water is total by cooling tower water inlet
The branched pipe managing and being connected to water inlet manifold flows into cooling tower.Connected one by branch pipe(tube) after cooling tower outfall sewer branch
Cold 22, every pipeline branch road has a cooling water pump 23 providing power for cooling water recirculation system.
When indoor institute chilling requirement is less, cold 22 is temporarily in holding state, and the temperature of cooling water is too low, cold
Will there is startup abnormal phenomena in 22 follow-up needs startups, meanwhile, if cooling water temperature is relatively low, cooling tower 21 then need not simultaneously
Opening multiple stage, now cooling tower 21 was opened and cooling water temperature can be made further to reduce at most, had both been unfavorable for that energy-conservation being also beneficial to sets
Standby maintenance.Making following improvement for this problem, the cooling tower water inlet manifold of described cooling tower 21 is provided with for detecting water temperature
The first temperature sensor 211, the outfall sewer of described but tower be provided with for detect supply mains's water temperature second temperature pass
Sensor 212, every described cooling tower 21 is provided with converter 210 and is positioned at the valve 213 of every cooling tower water inlet pipe, and described
One temperature sensor the 211, second temperature sensor 212, converter 210 are connected to controller 3.
Thus, it is possible to the temperature of the cooling tower water inlet manifold gathered by controller 3, if this temperature and the temperature controlling setting
Spending low, controller then cuts out certain cooling tower valve 213 at interval of a period of time, simultaneously closes off the motor of this cooling tower 21, control
Device 3 processed interval is closed the time period of cooling tower 21 and cooling tower valve 213 and be can be adjusted to 5 minutes, whole control process until
The temperature close or identical that the coolant-temperature gage of the first temperature sensor 211 detection is preset with controller 3, when being embodied as, generally sets
A fixed temperature range, say, that the temperature that the coolant-temperature gage of the first temperature sensor detection and controller are preset is in the temperature allowed
Degree difference scope, controls not turn off cooling tower 21 and cooling tower valve 213, and now the operation quantity of cooling tower 21 keeps not
Become.
But, the temperature drift that the coolant-temperature gage of the first temperature sensor 211 detection is preset with controller 3, permitting in other words
In the temperature range permitted, controller 3 will be opened the valve 213 on cooling tower and control the first converter on cooling tower simultaneously
210 accelerate cooling tower work, in order to reduce water temperature.
During it should be noted that cooling tower 21 leaving water temperature is too low, the cold 22 being in holding state opens again follow-up
Dynamic meeting is impacted, and therefore in this utility model, the outfall sewer of described cooling tower 21 is provided with for detecting supply mains's water temperature
The second temperature sensor 212.Preferably, connected a cold 22 by branch pipe(tube) after cooling tower outfall sewer branch, every
Pipeline branch road has a cooling water pump 23 providing power for cooling water recirculation system, and told cooling water pump is provided with the second change
Frequently device 230, the second temperature sensor 212 detects from cooling tower cooling water temperature out less than the water temperature set, then control
Device 3 processed will control the second converter 230 on cooling water pump, and the second converter 230 turns the power of water pump down to reduce cooling
The flowing velocity of water, improves the water temperature of the outfall sewer of cooling tower 21.
Second temperature sensor 212 detects from cooling tower 21 cooling water temperature out higher than the water temperature set, then
Controller 3 will control the second converter 230 on cooling water pump 23, and the second converter 230 tunes up the power of water pump to improve
The flowing velocity of cooling water, reduces the water temperature of the outfall sewer of cooling tower 21.
Further, after controller 3 collects the holding state of cold 22, and the second temperature sensor 212 detect cold
But the water temperature of tower 21 outfall sewer is less than preset temperature, and all for stopping cooling water pumps 23 are run by controller 3.
After controller 3 collects the holding state disappearance of cold 22, then original for startup cooling water pump 23 is run, and
Running frequency is compared to be adjusted controlling with preset temperature according to the water temperature of cooling tower outfall sewer.
