Description
Technical field
The present invention relates generally to field of heating ventilation air conditioning, particularly relates to a kind of air conditioner cooling tower system based on half-closed space.
Background technology
Cooling tower is the important component part of heating ventilation air-conditioning system, its effect is that the recirculated water carrying waste heat is carried out heat exchange at Ta Nei and air, the delivered heat of water is spilt into air to air, lowers the temperature to recirculated water.The quality of cooling tower runnability directly affects the effect of air-conditioning system cooling and warming.
The factor affecting cooling tower runnability comprises the layout etc. of air ' s wet bulb temperature, air mass flow, the water yield, cooling tower, and wherein the position of cooling tower and mode affect one of very crucial factor of cooling tower runnability quality.Cooling tower, once arrange unreasonable, will cause damp-heat air back-mixing, thus drastically influence cooling tower runnability.So in order to reduce cooling tower damp-heat air back-mixing, draughty outdoor placed usually by cooling tower, as roof or ground, and require that exhaust outlet, air inlet are unobstructed.
But cooling tower is positioned over roof or ground, very large for generation noise is affected whole building simultaneously attractive in appearance.In recent years, people are to urban environment growing interest, and cooling tower is placed in the space that the refrigerating plant room of special outer wall or building conversion layer etc. relatively close more and more; In addition along with the increase of single building construction area, the quantity of required cooling tower gets more and more.When a large amount of cooling towers is disposed in a half-closed space, following problem will be caused: the damp-heat air that 1, air and recirculated water carry out exchange heat generation can not discharge half-closed space well, and damp-heat air back-mixing rate is higher; 2, it is not smooth that Cooling Towers runs interference mutually, cooling tower enters air draft short circuit, air draft; 3, the cooling tower intake near half-closed space air inlet is excessive, and the cooling tower intake occupy in the middle part of half-closed space is too small, and blower fan of cooling tower type selecting is difficult to determine, cooling tower operational efficiency is low.These problems cause cooling tower at Effec-tive Function under declared working condition, thus can not directly affect the effect of whole air-conditioning system cooling and warming.
At present, outdoor cooling tower arranges that the simple engineering experience that relies on is carried out, and obtains good cooling effect.If but rely on merely engineering experience to carry out arranging and adopt outdoor Cooling Towers layout design method for the layout of Cooling Towers in half-closed space, part cooling tower runnability will be made to worsen, thus affect whole heat pump performance operational effect, therefore must find the prioritization scheme of Cooling Towers arrangement and raising Cooling Towers runnability in another half-closed space.
