The second control valve and the 4th control valve are opened, and starts refrigeration host computer system, now, the water in pond is buffered by low capacity and followed
Ring supplements cooling.
To reach purpose described in utility model content, the technical solution adopted in the utility model is as follows：
1. be incubated water storage pool according to air-conditioning end institute compass of competency area, ensure or consider cold-storage ability and reach to put
Cold period main frame is tried one's best idle purpose, determines water cistern size, and can be used more ponds or be separated into the method for more lattice, and
And also do not change water quality because water is not lost, it can be shared completely with fire-fighting water storage pool volume, as long as ensureing that the water in pond is abundant
Circulative convection, design capacity parameter calculation refer to following table：
Reach how many degree conversion valves and startup refrigeration host computer 2. specifically letting cool period water temperature and rising, will be according to air-conditioning end
Design capacity and the adjustment of site environment temperature requirements.
3. because QInhale=QPutCm △ t, so according to the specific heat principle of water, in a word regardless of air-conditioning or equipment end backwater
Mixed with the chilled water in pond, as long as having the water of enough capacity, storing the specified cold of foot, ensure that the water of water storage pool can be uniformly
In the case of convection current, how many cold have been stored, how many cold (no meter insulation pond loss certainly) can have just been released, as long as premise meets
Unit safety operation and condition needed for end switched environment；And work as end switching equipment environmental factor and exchange capacity and parameter phase
Meanwhile no matter the big temperature difference of low discharge that other both expensive costs configure a large amount of water-locator modes, might as well install complicated labyrinth
Formula, in the case of the water temperature difference identical of water storage pool, effective cold-storage and the cold released are equal.
4. the first control valve and the 3rd control valve outlet pipeline in as shown in Figure 1 are by the way of pond is arrived in scattered watering
It more can ensure that the formation convection current in pond and reach even water temperature；Outlet pipeline is because of buffering at second control valve and the 4th control valve
Pond capacity is small and can flow directly into buffering pond, is not required to scattered mouth.
5. by letting cool pump 9 in Fig. 1, end is supplied to or chilled water that plate changes, can not be changed by plate and directly be supplied to end
Equipment, and insulation open type header tank is installed additional (if pond is in the case of roof certainly at air-conditioning end or equipment highest order
More plate is not needed to change and open type header tank), it can so reduce because plate changes the temperature difference of loss to improve more Discharging times and effect
Benefit, but the caliber for doing the high lift for letting cool water pump and increasing return pipe can be carried, so if having ready conditions, it can also pass through confession
The temperature difference of return pipe adjusts the open degree of the 3rd control valve or the 4th control valve, without the side by the secondary exchange of plate swap-in row
Formula reaches peak efficiency.
6. switching is opened, close the condition of the first control valve and the 3rd control valve and be：Letting cool the period, (one simple
Timing controlled can be completed), when the water temperature in pond rises, the condition of letting cool can not meet needed for air-conditioning end or devices exchange
When, after temperature sensor detection reaches setting value in intermediate pool, refrigeration host computer+refrigeration pump+supporting cooling system will be started
System, pond cooling is buffered by low capacity, and refrigeration host computer refrigeration design temperature now can be controlled in conventional 7 DEG C (main frame has
Menu is predeterminable, or can manually set), to avoid causing unnecessary waste at peak or usually section；Remaining time first
Control valve and the 3rd control valve open (normally opened), and the second control valve and the 4th control valve close (normally closed), no matter refrigeration host computer is opened
Machine does not affect with standby.
7. power network peak value or usually section are discharging, it need to only run and let cool pump；Other refrigeration host computer system, refrigerating water pumps
Group, cooling pump group, cooling tower etc. can all stop completely, be not required to start；The cold middle cooling water pump of conventional direct-furnish, cooling tower can be saved
Run Deng the free time, and more water pump operations in other cold-storage modes, so as to save operating cost, when temperature sensor is in electricity
Net peak value or when usually detecting close to preset temperature, can pass through automatic or manual (after alarm, manually opened) switch valve
Control starts cooling tower, cooling water pump, refrigerating water pump, refrigeration host computer afterwards.
The utility model is equally applicable to accumulation of heat operating mode and industry freezing, cooling system scheme.Letter is counted and operates with throwing
List, cost of investment are few, the low advantage of technology.
As shown in figure 1, being the schematic diagram that the utility model simplifies chilled water storage system, the first control valve and the 3rd control valve are
Normally opened valve, the second control valve and the 4th control valve are normal closed gate, no matter day and night or refrigeration host computer are opened or stopped all is
Place is in this state；Uniquely only when power network peak or usually, and temperature rising in pond reaches the upper limit (10~14 DEG C adjustable)
Switch the first control valve and the 3rd control valve to close, the second control valve and the 4th control valve are opened, start refrigeration host computer system and
Matching pump system system realizes supplement (can also claim maintain cooling, the buffering cooling and direct-furnish cold) function of cooling, and limits chilled water
Only in the circulation in the buffering pond of low capacity, and refrigeration host computer can carry function according to unit and be set as 7 DEG C, in order to avoid in peak value
Or usually unnecessary charging occurs for section.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modification, equivalent substitution or improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
