Description
Technical field
The utility model relates to art of refrigeration units, specifically relates to a kind of device for handpiece Water Chilling Units chilled water forced circulation.
Background technology
Handpiece Water Chilling Units, is a kind of with electric energy drive compression machine, and circulating of driving cold-producing medium, is cooled to the chilled water of normal temperature state to meet the equipment that technological temperature requires endlessly.
The requirement of watering equipment for water at low temperature refrigerating capacity, flow depended in selecting of handpiece Water Chilling Units.And the compressor load adjusting range of handpiece Water Chilling Units has determined load adjustment scope and the refrigeration temperature drop scope of handpiece Water Chilling Units.In existing handpiece Water Chilling Units, in the situation that load increases, can only increase the quantity of handpiece Water Chilling Units, and can not in the situation that existing handpiece Water Chilling Units quantity is constant, adjust refrigerating capacity and the temperature drop scope of existing handpiece Water Chilling Units, the cost that makes to freeze significantly improves.
Utility model content
The purpose of this utility model is just to provide a kind of device for handpiece Water Chilling Units chilled water forced circulation, and this device is realized chilled water and in handpiece Water Chilling Units process of refrigerastion, obtained larger load adjustment scope and refrigeration temperature drop scope on the basis that does not increase existing handpiece Water Chilling Units quantity.
The utility model adopts following technical proposals:
A kind of device for handpiece Water Chilling Units chilled water forced circulation, comprise handpiece Water Chilling Units and the chilled water water pump and the industrial equipment that are connected with handpiece Water Chilling Units by pipeline respectively, also comprise forced circulation imported valve, forced circulation imported valve is connected by three-way pipeline with the outlet valve of handpiece Water Chilling Units, forced circulation imported valve is also connected with forced circulation water pump, forced circulation water pump is connected with forced circulation outlet valve, and forced circulation outlet valve is connected by three-way pipeline with the imported valve of handpiece Water Chilling Units; Described forced circulation water pump is also connected with pump variable frequency device.
Preferably, described forced circulation imported valve is connected by pipeline with forced circulation water pump, is also provided with thermometer on pipeline.
Preferably, on described pipeline, be also provided with Pressure gauge.
Preferably, described forced circulation water pump is connected with forced circulation outlet valve by pipeline, is also provided with flowmeter on pipeline.
Operation principle of the present utility model is: chilled water water pump is sent chilled water into handpiece Water Chilling Units, chilled water is flowed through cooling after handpiece Water Chilling Units, cooled chilled water part flows into industrial equipment, part is extracted out by forced circulation water pump, then mix with the chilled water of normal temperature through forced circulation outlet valve, again repeat coolingly by handpiece Water Chilling Units, obtain larger load adjustment scope and refrigeration temperature drop scope.
The beneficial effects of the utility model are: in the case of not increasing the quantity of handpiece Water Chilling Units, by install the device of forced circulation additional in existing handpiece Water Chilling Units, obtain larger load adjustment scope and refrigeration temperature drop scope, significantly reduced refrigeration cost.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Wherein: 1, forced circulation water pump, 2, flowmeter, 3, forced circulation imported valve, 4, forced circulation outlet valve, 5, Pressure gauge, 6, pump variable frequency device, 7, thermometer, 8, industrial equipment, 9, handpiece Water Chilling Units, 10, outlet valve, 11, imported valve, 12, chilled water water pump.
Detailed description of the invention:
Embodiment 1: a kind of device for handpiece Water Chilling Units chilled water forced circulation, its structure is as shown in Figure 1: the chilled water water pump 12 and industrial equipment 8 that comprise handpiece Water Chilling Units 9 and be connected with handpiece Water Chilling Units 9 by pipeline respectively, also comprise forced circulation imported valve 3, forced circulation imported valve 3 is connected by three-way pipeline with the outlet valve 10 of handpiece Water Chilling Units 9, the other end of three-way pipe is connected with handpiece Water Chilling Units 9, forced circulation imported valve 3 is also connected with forced circulation water pump 1, forced circulation water pump 1 is connected with forced circulation outlet valve 4, forced circulation outlet valve 4 is connected by three-way pipeline with the imported valve 11 of handpiece Water Chilling Units, the other end of three-way pipeline is connected with handpiece Water Chilling Units 9, described forced circulation water pump 1 is also connected with pump variable frequency device 6.
Described forced circulation imported valve 3 is connected by pipeline with forced circulation water pump 1, is also provided with thermometer 7 on pipeline, is also provided with Pressure gauge 5 on this pipeline.
Described forced circulation water pump 1 is connected with forced circulation outlet valve 4 by pipeline, is also provided with flowmeter 2 on this pipeline.
After handpiece Water Chilling Units 9 runs well, open forced circulation imported valve 3 and forced circulation outlet valve 4, start forced circulation water pump 1; After forced circulation water pump 1 is pneumatic, the chilled water forced circulation of part low temperature is arrived to the import to handpiece Water Chilling Units 9; After the chilled water being extruded with refrigerant water pump 12 by the low temperature chilled water of forced circulation mixes, again enter the cooling chilled water of producing lower temperature of handpiece Water Chilling Units 9.
Observe the demonstration data of flowmeter 2 and thermometer 7, adjust according to demand pump variable frequency device 6, and then adjust the extrusion water yield of forced circulation water pump 1, change the temperature of chilled water.
By adopting said structure, this programme, in the case of not increasing the quantity of handpiece Water Chilling Units 9, by install the device of forced circulation additional in existing handpiece Water Chilling Units 9, obtains larger load adjustment scope and refrigeration temperature drop scope, has significantly reduced refrigeration cost.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendments that creative work can make or distortion still in protection domain of the present utility model.
