Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:
Fig. 1 is the schematic diagram of specific embodiment of the utility model; And
Fig. 2 is the schematic diagram according to a kind of concrete connected mode of the utility model central air conditioner system.
The specific embodiment
First embodiment
As shown in Figure 1, centrifugal water chillers 10 next doors are provided with one or more hot sound refrigerating machines 20.Hot sound refrigerating machine 20 comprises towards the horn mouth 21 of handpiece Water Chilling Units, resonatron 22, hot end heat exchanger 23, cool end heat exchanger 24 and the regenerator between hot end heat exchanger 23 and cool end heat exchanger 25.Hot end heat exchanger 23 is provided with cooling water inlet pipe 26 and cooling water outlet pipe 27, and cool end heat exchanger 24 is provided with cold water inlet 28 and cold water outlet pipe 29.Cooling water inlet pipe 26 links to each other with the cooling water system of cooling water outlet pipe 27 with centrifugal water chillers 10.Cold water inlet 28 links to each other with the chilled water system of cold water outlet pipe 29 with centrifugal water chillers 10, cold water in the chilled water system of centrifugal water chillers 10 flows out the back and enters from cold water inlet 28 earlier from unit, further flow out from cold water outlet pipe 29 the cooling back, send into user side and use, so can obtain more cold for refrigeration.Certainly, cold water also can be to shunt a part of cold water by a minute pipeline to enter cold water inlet 28 after flowing out from unit, converges with former cold water main line after cold water outlet pipe 29 flows out again, and sends into user side for using.
Hot end heat exchanger 23, cool end heat exchanger 24 usefulness red coppers are that materials processing becomes the plate stack structure, and regenerator 25 adopts stainless steel cloth, and resonatron adopts stainless steel tube.Horn mouth 21 is introduced sound wave, and according to sound refrigeration principle, hot sound refrigerating machine arrives the regenerator hot junction with the cold junction transfer of heat of regenerator 25, makes the water refrigeration in the cool end heat exchanger 24 like this, and this water is input to user side, to alleviate the cooling load of handpiece Water Chilling Units.
Second embodiment
In the present embodiment, hot sound refrigerating machine has the parts identical with first embodiment, and difference is that cooling water inlet pipe 26 links to each other with a cooling water system that is provided with separately with cooling water outlet pipe 27.This cooling water system can be arranged near the handpiece Water Chilling Units, utilizes with the temperature difference of environment and lowers the temperature naturally.In the utility model, the radiating mode in hot sound refrigerating machine hot junction can not adopt the mode of water-cooled, and is only undertaken by the heat exchange between hot end heat exchanger 23 and the atmosphere.
