Through the second regulating valve DV2, the 16th regulating valve DV16, the 12nd regulating valve DV12, the tenth regulating valve DV10, lower water distribution after cooling
Device 52 enters cold-storage water pot 5.
Further, the secondary water at low temperature in cold-storage water pot 5 is through upper water distributor 51, the 9th regulating valve DV9, the 11st regulating valve
DV11, the 17th regulating valve DV17 enter subcooler 3a by the way that pump 7, third regulating valve DV 3, subcooler water inlet pipe 3a1 is subcooled,
Temperature increases after obtaining heat, by the 4th regulating valve DV4, the 14th regulating valve DV14, time with the cold-storage water pot 5 outflow
Water at low temperature mixes in cold-storage water pot return duct 511, and a mixing water part carries out next round charge cycle through cold-storage water pump 6, mixes
Heshui another part carries out next round by water supply pump 7 and crosses SAPMAC method.
Further, the water at low temperature in cold-storage water pot 5 is adjusted through lower water-dispensing device 52, the tenth regulating valve DV10, the 23rd
Valve DV23, by letting cool water pump 14, from 131 inflow heat exchanger 13 of heat exchanger water at low temperature water inlet end, water at low temperature is handed over through overheat
The secondary water at low temperature become after changing is flowed out from secondary water at low temperature water outlet 132, and after the 22nd regulating valve DV22, a part is through the
18 regulating valve DV18, charge cycle is entered by cold-storage water pump 6；A part passes through subcooled water through the 17th regulating valve DV17
Pump 7 entered SAPMAC method；Remainder enters cold-storage water through the 11st regulating valve DV11, the 9th regulating valve DV9, upper water distributor 51
In tank 5.
Cold accumulation system simultaneously cold-storage and discharging cold course, because cold storage capacity, let cool with cross cold variation, can cold-storage water pot,
Cold-storage water pump, let cool water pump, supercooling water pump and relevant regulating valve between generate many operating conditions, the utility model can root
It is controlled and is adjusted according to actual demand.
Further, the flow of cold-storage water pump 6 is computed determining with lift according to cold storage capacity and the cold-storage temperature difference.
Further, the flow of supercooling water pump 7 is computed determining according to supercooling temperature with lift with crossing cold flow.
Further, the flow for letting cool water pump 14 is computed determining according to the amount of letting cool with lift with letting cool temperature difference.
The present embodiment can improve the cold storage capacity of cold-storage sink, improve the refrigerating capacity of handpiece Water Chilling Units and reduce handpiece Water Chilling Units
Power consumption.
Cold accumulation system cold-storage and is let cool typically in electricity consumption ebb simultaneously, it is still necessary to be carried out in the case of using cold
's.Cold-storage water pot one side cold-storage at this time, lets cool on one side.When the unit of user terminal is more, need cold larger, at this time cooling-water machine
The acceptable cooling simultaneously of group.
The utility model realizes the peak load shifting of handpiece Water Chilling Units electricity consumption；Increase the cold storage capacity and cooling-water machine of cold-storage water pot
The refrigerating capacity of group reduces the electricity consumption of handpiece Water Chilling Units；Save the operating cost of cooling process.
Above-described is only the principle and preferred embodiment of the utility model.It should be pointed out that for the general of this field
For logical technical staff, on the basis of the utility model principle, several other modifications can also be made, also should be regarded as this practicality
Novel protection domain.
