Pipeline and valve connected system that said water-cooled handpiece Water Chilling Units and plate type heat exchanger are imported and exported.
It is single that the utility model has solved available data machine room refrigeration form, big and the high a series of problems of initial cost of energy consumption for cooling, the utility model provides a kind of refrigerating method and mentality of designing, this method adopts conventional equipment, initial cost changes less, adopts multiple refrigeration mode, according to outdoor temperature and chilled water return water temperature, at any time switch refrigeration mode, effectively reduce energy consumption for cooling.
The utility model is achieved with following method, promptly when summer during outdoor high temperature, adopts conventional refrigerating method, i.e. handpiece Water Chilling Units refrigeration, and cooling tower is as the condenser side heat transmission; When winter, outdoor temperature was low, adopt the cooling tower refrigeration, after the heat exchanger heat exchange, secondary cold water is conducted to air conditioning terminal; Transition season adopts joint refrigeration, promptly at first adopts the cooling tower refrigeration, does not set when requiring when heat exchanger outlet temperature reaches, and cold water enters handpiece Water Chilling Units and carries out the secondary cooling, sends into end after reaching setting value, reaches purpose of energy saving.
Description of drawings
Accompanying drawing is the utility model refrigeration system switching principle figure.
Be description of reference numerals in the utility model Figure of description below:
1, water-cooled handpiece Water Chilling Units 2, plate type heat exchanger
3-1,3-2,3-3,3-4,3-5,3-6, valve
4, water return pipeline 5, water supply line
The specific embodiment
Shown in accompanying drawing, water return pipeline 4 is divided into two-way, one the tunnel connects import, the outlet of water-cooled handpiece Water Chilling Units 1, valve 3-3, the water supply line 5 of valve 3-1,3-2, water-cooled handpiece Water Chilling Units 1 successively, and another road connects import, the outlet of plate type heat exchanger 2, valve 3-6, the water supply line 5 of valve 3-4, plate type heat exchanger 2 successively; In addition, adopt pipeline through valve 3-5,3-2 plate type heat exchanger 2 outlets to be connected with 1 import of water-cooled handpiece Water Chilling Units successively.The pipeline that water-cooled handpiece Water Chilling Units 1 and plate type heat exchanger 2 are imported and exported and valve 3-1,3-2,3-3,3-4,3-5,3-6 connected system.
Operation principle of the present utility model is: freezed by 1 work of water-cooled handpiece Water Chilling Units when outdoor high temperature; During outdoor low temperature by plate type heat exchanger 2 work refrigeration; When outdoor temperature is lower, and only can't meet the demands the time, adopt plate type heat exchanger 2 and 1 associated working of water-cooled handpiece Water Chilling Units refrigeration by plate type heat exchanger 2 work, plate type heat exchanger 2 is preferential.Chilled water infeeds end by water supply line 5 the most at last, and after terminal heat exchange, chilled water is back to refrigeration plant through water return pipeline 4 and continues cooling.
As above scheme described, the utility model data air conditioner in machine room nature cooling system:
Being 7/12 ℃ with the chilled water supply and return water temperature is the example explanation, and this temperature can freely be set as required
Equipment and valve switching controls pattern: during summer temp higher (wet-bulb temperature＞8 ℃), adopt conventional handpiece Water Chilling Units refrigeration, promptly close 3-4,3-5,3-6 valve, chilled water enters water-cooled handpiece Water Chilling Units 1 by chilled water return pipe 4 through valve 3-1,3-2, after 1 heat exchange of water-cooled handpiece Water Chilling Units, by valve 3-3, send into end by chilled water feed pipe 5 again; When outdoor temperature in winter lower (wet-bulb temperature≤3 ℃), utilize nature to cool off refrigeration fully, promptly close 3-1,3-2,3-3,3-5 valve, chilled water enters plate type heat exchanger 2 by chilled water return pipe 4 through valve 3-4, after plate type heat exchanger 2 heat exchange, by valve 3-6, send into end by chilled water feed pipe 5 again; In the time can't utilizing nature when cooling (3 ℃＜wet-bulb temperature≤8 ℃) fully, adopt plate type heat exchanger and handpiece Water Chilling Units joint refrigeration, promptly close 3-1,3-6 valve, chilled water enters plate type heat exchanger 2 by chilled water return pipe 4 through valve 3-4, after plate type heat exchanger 2 heat exchange, enter water-cooled handpiece Water Chilling Units 1 by valve 3-5,3-3 and carry out secondary cooling, reach design temperature after, by valve 3-3, send into end by chilled water feed pipe 5 again.Because this refrigeration system has made full use of outdoor natural cooling source, is example with the Xi'an meteorologic parameter, one 850 standard ton, the water-cooled handpiece Water Chilling Units of nominal power consumption 500kW, year about 1,500,000 kW.h of saving electricity consumption.This refrigeration system can fully be applied to severe cold area, cold district and Xia Redong cryogenic region.
