Description
Technical field
The present invention relates to a kind of cooling-fan installation, particularly a kind of natural cooling ventilating system。
Background technology
In communications equipment room, communication equipment generates heat throughout the year, and heat dissipation capacity is big, even if remaining a need in the winter time adopting air conditioner refrigerating to reduce indoor temperature, it is ensured that communication equipment properly functioning, and the air conditioning energy consumption brought therefrom is very big。In severe cold area, the air conditioning system of communications equipment room in the winter time time must avoid in cooling water pipeline and cooling tower freezes, and electric tracing can only be increased under normal circumstances and solve。
Outdoor in winter, severe cold area possesses substantial amounts of free low-temperature receiver cold air, if outdoor natural cooling source being introduced the heat eliminating room in machine room, reducing temperature in machine room, thus reducing the Energy in use of winter air-conditioning system, can reach to save electric energy, reduce the purpose of communications equipment room operation cost。
Severe cold area utilizes outdoor cold source mainly to have three kinds of modes:
1) direct new air cooling: directly new for outdoor wind is sent in machine room, when outside air temperature is relatively low, it is possible to directly outdoor Cryogenic air is delivered to indoor, for room temperature lowering；
2) outdoor air cools down indirectly: be not introduced directly into new wind, adopts the equipment such as heat exchanger that outdoor cold is introduced indoor, thus reaching purpose indoor temperature reduced。
3) outdoor cooling tower is air conditioning unit offer low-temperature receiver。
If being introduced directly into outdoor new wind directly cool down room air and equipment, High-cfficiency Filtration equipment need to be increased to ensure the communications equipment room requirement to air purity, and sand and dust area outdoor air dustiness is higher, particularly in the winter time and the Spring Festival, drainage screen very easily blocks, and not only causes maintenance cost to raise, and sand and dust blocking filtration system, equipment may be affected properly functioning, reduce the operational reliability of refrigeration system。Under normal circumstances, the method cannot use。
Cooling tower cooling need to increase electric tracer heating system and ensure to run, and energy consumption increases accordingly。
Summary of the invention
The invention aims to solve the deficiency of above-mentioned technology and the natural cooling ventilating system suitable in severe cold sand and dust area communication machine room is provided, heat convection is carried out by exposed at outdoor airduct and outdoor cold air by room air, being cooled down by air in airduct, indoor are delivered in circulation。
In order to achieve the above object, natural cooling ventilating system designed by the present invention, it mainly includes airduct and is respectively arranged with air inlet and air outlet at the two ends of airduct, described air inlet all connects with indoor machine room with air outlet, described airduct is disposed in the outdoor, and in described airduct, it is provided with the blower fan that circulation of air flow power is provided, and the mid portion of described airduct is enhanced heat exchange section, described enhanced heat exchange section is the axially uniform many minor diameter heat exchanger tubes at airduct。Being characterized in that of this structure, utilizes hot blast in outdoor relatively low temperature cooling duct, then the cold wind cooled down is looped back indoor, improves heat exchange efficiency in particular with aluminum veneer airduct and minor diameter heat exchanger tube。
Preferably, described airduct is internal to be supported by steel structure framework, has special rubber sheet gasket in airduct and steel structure framework construction, to improve the intensity of airduct, and reduces vibration, reduces noise。
Preferably, it is connected by glass hose coupling between described blower fan and airduct, it is to avoid the vibration of machine is directly passed to airduct。
Preferably, described BOD is provided with condensate collector, and condensate collector is connected with the floor drain in machine room by condensate pipe, and BOD and condensate pipe are equipped with electric tracing thermal insulation device。To prevent the phenomenon such as frosting, frost。
Preferably, described airduct is of a size of 2400～2000 × 1500mm, and airduct adopts thickness to be the aluminum veneer of 3mm, is combined with wall of communication equipment room facade, can promote building overall appearance degree。
As priority scheme, described minor diameter heat exchanger tube diameter is 200mm, and length is 8000mm arrangement mode is 7 × 7, arranges interval 100mm, between-line spacing 200mm, has reached the ratio optimization of heat exchange efficiency and cost of investment。
Natural cooling ventilating system designed by the present invention, utilizes outdoor relatively low temperature, freely lowers the temperature and reaches to save the effect of the energy。Use the natural cooling ventilating system designed by the present invention, the temperature difference between air inlet and air outlet can be made to differ about 10 DEG C, be fully achieved the cooling-down effect required by communications equipment room。Also having structural strength height, airduct vibration is little, and noise is low simultaneously, the investment feature that gain quick return。
