Refrigerated module cooling condition: using outdoor low temperature cold source is cooling in machine room, during winter (outdoor environment temperature is less than or equal to-10 DEG C), for avoiding the icing at cooling tower, cut off cooling tower, Intermediate Heat Exchanger and cold water main unit, use refrigerated module, i.e. wind-water-to-water heat exchanger, the cold air directly utilizing outdoor is chilled water cooling, refrigerated module has blower fan, chilled water can directly feed in machine room, or by coolant distributor, cold is passed to intermediary, the heat in machine room is taken away by the circulation of chilled water or intermediary, chilled water after heat absorption returns to Intermediate Heat Exchanger cooling, complete a circulation.
Control logic between each operating mode is as follows:
When outdoor temperature is more than 20 DEG C, opening cold water main unit and cooling tower, now cooling water circulates between cold water main unit and cooling tower；When outdoor temperature is less than or equal to 20 DEG C more than 0 DEG C, closing cold water main unit, open cooling tower and Intermediate Heat Exchanger, now cooling water circulates between Intermediate Heat Exchanger and cooling tower；When outdoor environment temperature is less than or equal to 0 DEG C, closing cold water main unit and the blower fan of cooling tower, open spray equipment and the Intermediate Heat Exchanger of cooling tower, now cooling water circulates between Intermediate Heat Exchanger and cooling tower；When outdoor environment temperature is less than or equal to-10 DEG C, close cold water main unit and cooling tower, open refrigerated module, now no-cooling-water circulation.
It is the cooling of machine room electronic equipment that this utility model patent directly utilizes natural cold quantity abundant in nature, and this refrigeration station is free of discontinuities in 1 year 365 days provides low-temperature receiver for machine room, can substitute traditional air conditioner completely.During outdoor high temperature, using handpiece Water Chilling Units to provide chilled water for machine room, wherein handpiece Water Chilling Units uses cooling water temperature, can provide efficiency more than 30% relative to cooling by wind；When outdoor temperature is relatively low, directly utilizing natural cooling source by cooling tower or refrigerated module is that machine room is lowered the temperature, and now without opening handpiece Water Chilling Units, is substantially reduced energy consumption for cooling.This utility model patent increases Intermediate Heat Exchanger and refrigerated module on the basis of conventional refrigeration, makes full use of the outdoor low temperature cold source in transition season and winter, reduces the operation time of cold water main unit, reduces the energy consumption of refrigeration system；This system can make up the problem that winter, conventional refrigeration was shut down without defence program during high-low pressure because of compressor simultaneously, it is ensured that the refrigeration capacity requirement of machine room.
The outlet side of chilled water system is provided with bypass branch, and bypass branch is serially connected with bypass valve, and bypass branch is in parallel with refrigerated module；Bypass valve effect is notable, mainly regulates the temperature of chilled water, if the load in machine room is little, then partial freeze water backwater does not enter handpiece Water Chilling Units, directly in bypass valve (bypass branch) to chilled water water supply conduit.
Chilled water is provided to be prior art for chilled water system.Such as supplied water by coolant distributor, and coolant distributor obtains chilled water from refrigeration terminal.
Beneficial effect:
Multi-source heat pipe energy-saving system of the present utility model, Intermediate Heat Exchanger and cold water main unit share cooling water and chilled water for water return pipeline；Described cold water main unit and Intermediate Heat Exchanger are based on outdoor temperature and by multiway valve switchover operation；Described control system includes temperature sensor and controller.This utility model patent increases Intermediate Heat Exchanger and refrigerated module on the basis of conventional refrigeration, makes full use of the outdoor low temperature cold source in transition season and winter, reduces the operation time of compressor, reduces the energy consumption of refrigeration system；This system can make up the problem that winter, conventional refrigeration was shut down without defence program during high-low pressure because of compressor simultaneously, it is ensured that the refrigeration capacity requirement of machine room.
This utility model patent compared with prior art, has significant energy-saving effect.Integration multi-source refrigeration station, i.e. energy conserving system utilize natural cold quantity abundant in cold water main unit and nature to lower the temperature for machine room electronic equipment, and outdoor cold air not directly enters machine room, it is ensured that the purity requirements in machine room；This utility model patent increases Intermediate Heat Exchanger on the basis of tradition cold water main unit refrigeration system, makes full use of the outdoor low temperature cold source in transition season and winter, reduces the operation time of cold water main unit, reduces the energy consumption of refrigeration system；Cold water main unit uses cooling water system to reach the effect of condensation, improves efficiency more than 30% than traditional air cooling system；This system can make up the problem that winter, conventional refrigeration was shut down without defence program during high-low pressure because of compressor simultaneously, it is ensured that the refrigeration capacity requirement of machine room.Additionally, this integration multi-source refrigeration station is that in machine room, end refrigeration system provides low-temperature receiver, traditional refrigeration system can be replaced completely to run.
This utility model patent can realize the refrigeration cool-down in machine room in the range of the whole year, overcome the shortcoming that conventional refrigeration cannot utilize natural cooling source, it is to avoid in air conditioner energy-saving system, VMC (Ventilation Mechanical Control System) and air heat-exchange system cannot the shortcomings of whole year operation；The Shuan Leng refrigeration station system used, the wherein cooling in machine room in time meeting outdoor high temperature of cold water main unit system, and use and cooling water circulation take away condensation heat extraction, improve the work efficiency of cold water main unit；Cooling in machine room and energy-conservation when Intermediate Heat Exchanger system meets outdoor low temperature, directly using cooling tower in the winter time with excessive season is low-temperature receiver, is taken away the heat in machine room by Intermediate Heat Exchanger.
