Description
Technical field
The present invention relates to the cooling apparatus that utilizes the indirect evaporation cooling that a kind of field of heating ventilation air conditioning is used, belong to energy technology field.
Background technology
China's building energy consumption accounts for 30% of social total energy consumption, and the heating and air-conditioning system energy consumption is occupied important ratio in whole building energy consumption.The energy crisis that produce the seventies in 20th century under the pressure that oil price rises suddenly and sharply, started the climax of building energy conservation rapidly, so evaporative cooling (Evaporative Cooling) technology is arisen at the historic moment.This air-conditioning unit is provided cold by evaporation of water, evaporation again behind the aqueous water is got back in the compressed again condensation of steam after it will not evaporate, direct supplementing water the carrying out of assigning to keep evaporation process, thereby can save operation energy consumption greatly.And reduction of greenhouse gas discharge and ozonosphere protection in recent years become the two overall situation problems that the whole world is paid close attention to: evaporative cooling is cold-producing medium with water, does not use CFC, and is pollution-free thereby be subjected to more paying attention to widely to atmospheric environment.Therefore, evaporation cooling technique receives the close concern of people day by day.
Evaporation cooling technique utilizes the evaporation heat-absorbing action of moisture, makes air or water for cooling, reaches the purpose of refrigeration.Its core content is to utilize the undersaturated condition of surrounding air to freeze, and promptly the cooling potentiality that have of surrounding air itself are especially more obvious in dry regional cooling effect.Picture is in areas such as Xinjiang of China, and summer, outdoor temperature height but humidity is very low utilized the evaporative cooling effect of surrounding air, can directly prepare cold water or cold air, supplies with air-conditioning system and uses.
Evaporation-cooled device mainly is divided into the combination of direct evaporation-cooled device, apparatus for cooling by indirect evaporation and two kinds of forms.Air is in direct evaporation-cooled device, and temperature reduces, humidity (water capacity) increases, and ideally can obtain the low-temperature receiver of air ' s wet bulb temperature.Apparatus for cooling by indirect evaporation can obtain the low-temperature receiver of air dew point temperature in the ideal case.After air cooled off through indirect evaporation, temperature reduced, water capacity does not change.For example: when the temperature of outdoor air be 35 ℃, when relative humidity is 30%, the wet-bulb temperature of outdoor air and dew-point temperature are respectively 21.3 ℃ and 14.8 ℃.Because apparatus for cooling by indirect evaporation can be prepared the lower low-temperature receiver of temperature, thereby important application prospects is arranged in air-conditioning system.
Summary of the invention
The object of the present invention is to provide a kind of good energy-conserving effect, the environmentally friendly cooling apparatus that utilizes indirect evaporative cooling technology.
A kind of cooling apparatus that utilizes the indirect evaporation cooling that the present invention proposes, it is characterized in that: described device contains the direct contact modules 1 of gas-liquid, air-water-to-water heat exchanger 2, air-to-air heat exchanger 3, blower fan 4, water pump 5;
The lower end of the direct contact modules 1 of described gas-liquid links to each other with air-water-to-water heat exchanger 2 by water pump 5, further cools off processed air for self, and the other end directly links to each other with the user by pipeline.
One end of described air-to-air heat exchanger 3 links to each other with the blower fan 4 that outdoor new wind is provided by pipeline, the other end and air-water-to-water heat exchanger 2 link to each other by pipeline, new wind enters air-water-to-water heat exchanger 2 and is further cooled, cooled cold air directly contacts the exchange of carrying out heat and quality with the water spray adverse current of the direct contact modules 1 of gas-liquid, air is heated humidification in this process, water is lowered the temperature, the air behind the warming and humidifying be admitted to air-to-air heat exchanger 3 further reclaim enter behind its energy outdoor.
Apparatus for cooling by indirect evaporation of the present invention, low-temperature receiver that can preparation room outer air dew-point temperature; Except required blower fan and water pump power, need not to import energy in the device, have good energy-saving effect; Adopt outdoor air and water as working media, pollution-free to atmospheric environment.
Description of drawings
Fig. 1 is an indirect-evaporation cooling device structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Referring to Fig. 1, this indirect-evaporation cooling device is made up of the direct contact modules 1 of gas-liquid, air-water-to-water heat exchanger 2, air-to-air heat exchanger 3 and energy delivery means.Energy delivery means comprises: blower fan 4, water pump 5.This device utilizes the evaporative cooling effect of moisture, and the cold water, the supply user that obtain low temperature use.The cold water that the direct contact modules 1 of gas-liquid flows out is divided into two strands, and one uses for apparatus for cooling by indirect evaporation self, and another strand supplied with the user and used.
The course of work of this indirect-evaporation cooling device is as follows:
Outdoor new wind is under the driving of blower fan 4, after at first passing through air-to-air heat exchanger 3 (heat regenerator) precooling, recovery energy of exhaust air, entering air-water-to-water heat exchanger 2 is further cooled, cooled cold air directly contacts the exchange of carrying out heat and quality with the water spray adverse current of the direct contact modules 1 of gas-liquid, and air is heated humidification in this process, water is lowered the temperature.Air behind the warming and humidifying be admitted to air-to-air heat exchanger 3 further reclaim enter behind its energy outdoor.The cold water that flows out from the direct contact modules 1 of gas-liquid is divided into two strands, and under the driving of water pump 5, one cold water flows to the further processed air of cooling of air-water-to-water heat exchanger 2, and another strand cold water is directly supplied with the user and used.Behind the water and the cold water mix after user's use through air-water-to-water heat exchanger 2, enter the direct contact modules 1 of gas-liquid.Ideally, in this indirect-evaporation cooling device, the temperature of output cold water is the dew-point temperature of outdoor new wind.
