Detailed description of the invention
Below with reference to the drawings and specific embodiments, the utility model is described in further details:
Embodiment 1:
As Fig. 1-2, a kind of zoned temperature control air-conditioning system, comprises refrigeration system, cold-storage system and heat-exchange system.Described refrigeration system comprises compressor 1, condenser 2, condensation fan 3, choke valve 4.Described cold-storage system comprises evaporation coil 5, storage cold water storage cistern 6, water circulating pump 7.Described heat-exchange system comprises surface cooler 8, pressure fan 9.Described control system comprises temperature sensor and microprocessor.Temperature sensor is connected with the input of microprocessor, and compressor 1, condensation fan 3, pressure fan 9, water circulating pump 7 are controlled by microprocessor.Described heat-exchange system comprises surface cooler, pressure fan, flow control valve.Described control system comprises temperature sensor and microprocessor.Temperature sensor is connected with the input of microprocessor, and compressor, condensation fan, pressure fan, water circulating pump, flow control valve are controlled by microprocessor.The air outlet of the surface cooler in described heat-exchange system directly contacts with the air inlet of base station heat-producing device.Described heat-exchange system adopts full air return system, and full air return system is to be connected by pipeline by the air outlet of surface cooler and the air inlet of heat-producing device.
The utility model can carry out to base station zones of different the control of temperature, does not need other space of equipment to carry out cooling, has reduced air conditioning area, thereby has reduced refrigeration duty, thereby improved the precision of heat-producing device environment control.The storage cold water storage cistern that it adopts is an airtight cool-bag, and the full heat exchange coil of container inner disc, can realize the quick heat exchange of cold-producing medium and refrigerating medium, and the chilled water that refrigeration system is produced stores, use to supply with heat-exchange system, can obviously reduce the start-stop time of refrigeration system, reduce energy consumption; While can be mains failure, provide simultaneously and answer quench low-temperature receiver for subsequent use, make the stability of system higher.
Work operating mode of the present utility model is divided into 3 kinds of operating modes, is respectively cooling condition, stores up cold operating mode, heat-exchanging state.
Cooling condition: refrigeration system mainly comprises compressor, condenser, choke valve, evaporation coil composition.By wanting compressor cooling circulation that cold is passed to cold-storage system, in the time that reaching the higher limit of setting, the temperature of storage cold water storage cistern (sets according to using the local temperature value maintaining that requires, generally be equal to or slightly lower than the higher limit of minimum requirements temperature range), compressor can start, condensation fan starts, cold-producing medium is delivered to evaporation coil by choke valve by low-temperature refrigerant, and cold is passed to cold water; When storage cold water storage cistern water temperature lower than set lower limit time, compressor, condensation fan quit work.[storage cold water storage cistern is equipped with temperature sensor]
Store up cold operating mode: cold-storage system is an airtight cool-bag, the full evaporation coil of container inner disc, can realize the quick heat exchange of cold-producing medium and refrigerating medium, and cold made refrigeration system is stored with cold water form, for heat-exchange system practicality, can obviously reduce the start-stop time of refrigeration system, thereby reduce widely energy consumption, also can be while power failure and provide cooling low-temperature receiver for subsequent use, the stability of system is improved in certain degree simultaneously.
Heat-exchanging state: heat-exchange system is mainly made up of surface cooler, pressure fan, flow control valve.The return air of heat-producing device directly carries out heat exchange by surface cooler by return air duct, and then enter heat-producing device by air inlet, this refrigeration modes directly to heat-producing device lower the temperature with according to the different feature of zones of different control temperature, reduce the air conditioning area of base station, thereby reduce air conditioner load, thereby improved the precision of heat-producing device environment control.When air conditioning area end return air temperature is set up in limited time higher than setting, water circulating pump starts, and pressure fan starts, and gives equipment fast cooling; When air conditioning terminal return air temperature lower than design temperature under in limited time, pressure fan stops, when all pressure fans stop, water circulating pump is out of service.In the time having a power failure, water circulating pump and pressure fan start to equipment cooling, when giving, return air during without the temperature difference water pump out of service, but pressure fan still moves, and is the heat radiation of equipment forced ventilation.
The utility model breaks down at air-conditioning, power failure or phase shortage, system works logic are abnormal, when water logging and smog, start alarm, and prompting can not be used for maintaining indoor temperature.Longer by the life cycle of air-conditioning unit compared with traditional base station, the life-span is longer, and heat transfer effect is better, more energy-conservation.
Zoned temperature control air-conditioning system of the present utility model, is particularly suitable for being applied in base station occasion, also can be used in the occasion that other caloric values are large.
