Abstract
The invention relates to a ventilating and air-conditioning cooling method of underground engineering for cooling an air-conditioning reservoir of an air-conditioning refrigeration system in underground engineering, wherein heat of condensation is dispersed into the air-conditioning reservoir. A heat pump cooling system is adopted to cool the air-conditioning reservoir, wherein an evaporator of the heat pump cooling system is directly used for cooling the air-conditioning reservoir. Two sets of condensers of the heat pump cooling system are connected in series, wherein the first set of the condensers are air-cooled condensers, and air outlets of the air-cooled condensers are led to the outside of the underground engineering; and the second set of the condensers are arranged at an air inlet of the underground engineering to heat fresh air entering from the outside of the underground engineering so as to ensure that the relative humidity in the underground engineering is not more than 70 percent. The invention provides a method and a device, which are used for the ventilation of the traditional underground engineering and adopt a cooling medium of an active central air-conditioning to cool. A cooling device is arranged underground, and under the condition of small air inlet and outlet amount of the device, the relative humidity in the underground engineering does not more than 70 percent.
Description
Technical field
The present invention relates to underground engineering heating ventilation and air-conditioning cooling means and device, especially the cooling means and the cooling device of underground engineering air-conditioning reservoir under the ventilation confined condition.
Background technology
Traditional underground protective engineering the time is thought in design and is not generally given the special project design of air-conditioning by the underground constant temperature that has; Expansion along with underground engineering area development and use scale; Owing to make the increase of electrical appliance and communication apparatus, cause the interior air-conditioning thermic load of engineering sharply to increase, caloric value increases; The temperature and humidity of underground engineering more can increase in summer; The interior air conditioner water warehouse temperature of engineering rises very fast, causes the rate of water make-up of original reservoir can't satisfy reservoir cooling requirement, makes that the air-conditioning system in the engineering can't normally be moved because of coolant water temperature is too high.Because engineering underground, can't adopt conventional ground cooling tower that the condensation heat of air-conditioning reservoir is discharged, and must condensation heat be discharged through underground ventilating system.But very little by the advancing of underground engineering air draft machine room, exhaust air rate, be about the 3000m3/100kw heat, one class air conditioner cooling tower (comprising existing wet cooling tower) has no idea the condensation heat in the engineering is discharged outside the engineering; In addition, the air draft machine room in the engineering also has other electric equipment, and the air that gets in summer does not allow directly to get into new wind in engineering internal face dewfall.
Summary of the invention
The present invention seeks to: propose a kind of underground engineering heating ventilation and air-conditioning cooling means and device; Especially the method and apparatus that the cooling medium of the active central air-conditioning of the ventilation of underground engineering and employing is cooled off.Underground, make the relative humidity in the underground engineering be no more than 70% at cooling device under the condition of the advancing of device, exhaust air rate very little (being about the 3000m3/100kw heat).
The present invention seeks to realize like this: underground engineering heating ventilation and air-conditioning cooling means; The air-conditioning reservoir that the condensation heat of air-conditioning refrigeration system in the underground engineering is dissipated to cools off; Adopt the heat pump cooling system that the air-conditioning reservoir is cooled off, wherein the evaporimeter of heat pump cooling system directly cools off the air-conditioning reservoir, and the condenser of heat pump cooling system is in series with two groups; First group is air-cooled condenser, and the air outlet of air-cooled condenser leads to outside the underground engineering; Second group of condenser is located at the air inlet of underground engineering, and the outer new wind that gets into of heating engineering makes the interior relative humidity of engineering be no more than 70%.
Air-cooled condenser adopts water spray mode can take away a large amount of heats through the evaporation of water mode; Air-cooled condenser adopts water spray mode can take away a large amount of heats through the evaporation of water mode; Cooler is can volume very little; Even cooler still is built in undergroundly, provides an outlet and takes away big calorimetric humid air and get final product.When air-conditioning refrigeration system in the engineering was worked, the condensation heat of air-conditioning system rose in order not make the air conditioner water warehouse temperature as for the air-conditioning reservoir; Adopt the present invention with the compressor in the engineering, chilled water pump, water circulating pump, advance, exhaust blower starts; Compressor is at first sent high-temperature high-pressure refrigerant steam into air-cooled condenser, and the outer new wind that gets into of heating engineering makes the interior relative humidity of engineering be no more than 70%; This air is sucked evaporative condenser by exhaust blower and carries out the wet exchange of heat; Heat is discharged outside the engineering, and the cold-producing medium of cooling refrigeration system makes it accomplish kind of refrigeration cycle simultaneously.
Underground engineering heating ventilation and air-conditioning cooling device of the present invention is provided with compressor, water-cooled evaporimeter, the heat pump cooling system that first condenser and second condenser constitute; First condenser and the series connection of second condenser; First condenser is an air-cooled condenser, and the air outlet of air-cooled condenser leads to outside the underground engineering, and second condenser is located at the air inlet of underground engineering; Be provided with chilled water pump and connect water-cooled evaporimeter and air-conditioning reservoir through pipeline, water circulating pump connects shower water to the first condenser.Condenser makes the interior relative humidity of engineering be no more than 70% to the outer new wind that gets into of air intake machine heating engineering.Compressor, startup, compressor is at first sent high-temperature high-pressure refrigerant steam into air-cooled condenser, the outer new wind that gets into of heating engineering.
Beneficial effect of the present invention is: propose the method and apparatus that a kind of cooling medium of active central air-conditioning of ventilation and the employing to existing underground engineering cools off.Cooling device is underground, under the condition of the advancing of device, exhaust air rate very little (being about the 3000m3/100kw heat), makes the relative humidity in the underground engineering be no more than 70%.The temperature that effectively solves the ubiquitous use of present underground engineering is too high, and the insurmountable difficult problem of cooling problem is for the control level that improves the protection works internal environment.
