Description

[0001] VENTILATION SYSTEM WITH HEAT EXCHANGING [0002]

The present invention is characterized in that outdoor air is heat-exchanged and collected through indoor air and mist sprayed water so that clean air having a temperature similar to indoor air is inputted into a room so that the temperature and humidity of the room are kept constant. And a ventilation system using the ventilation system.

Generally, air in an enclosed space increases the content of carbon dioxide and various harmful substances over time due to the breath of life, which hinders the breathing of life.

Therefore, when many people, such as offices and vehicles, stay in a narrow space, the contaminated air in the room must be replaced with fresh air from outside.

FIG. 1 shows a conventional waste heat recovery ventilator. In the waste heat recovery ventilator, an air supply duct 10 for introducing outdoor air into a room is provided in a box-shaped duct 1, The outdoor air being supplied to the room at the intersection of the air supply duct 10 and the exhaust duct 20 and the indoor air being exhausted to the outside, And a heat exchanger (30) for exchanging heat.

Such a conventional waste heat recovery ventilator is separately installed on the side of the air supply inlet 13 of the air supply duct 10 in order to prevent pollutants such as dust and dust contained in the outdoor air from being supplied to the room, However, such a filtering filter has a problem that it must be managed by replacing the filter periodically. Mostly, since the disposable consumable product causes a large maintenance cost, the filter having a short life span is used as industrial waste Thereby causing environmental pollution.

Such a waste heat recovery ventilator (or system) is required for a plastic house.

The vinyl house is a hiding place outside with vinyl. It is used to cultivate various kinds of vegetables, fruit trees, or flowering plants. It has high airtightness and high illuminance, , And water growth is comparable to that of glass greenhouse. In addition, since the covering material is light, the skeleton material is greatly reduced as compared with the glass greenhouse, and the installation cost is very low. However, , The thermal insulation can not be expected to be great, and the internal temperature of the greenhouse can not be properly maintained.

Therefore, in order to maintain the internal temperature of the greenhouse properly in winter so that crops can grow in the winter, a heating device such as a hot air heater and a boiler is installed to raise the internal temperature of the greenhouse.

However, in order to heat the inside of the plastic house, not only the economic burden of the farmer due to an increase in the installation cost for installing an expensive heating device for continuously supplying hot air and hot water, The fuel cost due to consumption of fuel (such as oil, light oil or heavy oil) is raised, and environmental pollution occurs due to excessive use of fuel.

Such waste heat recovery ventilator (or system) is also installed in a housing for high density breeding of chickens and pigs.

In general, harmful substances such as moisture, carbon dioxide, heat, dust and ammonia are generated in the housing by respiration of livestock, manure caused by feed and water ingestion, activity of livestock and heating of hot air fan. If the above mentioned harmful substances and occurrences are left inside the housing, it causes many diseases according to the climatic conditions, which causes problems of productivity and quality of the domestic animals. For example, colicosis in chickens is caused by the generation of ammonia gas, causing mortality, lowering feed efficiency and causing discoloration. In addition, bottles that cause quality deterioration such as chick embargo and umbilical inflammation are mostly caused by moisture and noxious gas.

Therefore, ventilation can be considered as a practical means to solve the above problems, and ventilation is indispensable for raising livestock.

The existing barn ventilation system has a fan to vent the air of the barn, so that the fan is operated at a fixed time or the fan is fixedly operated to replace the polluted air in the barn with the fresh air outdoors.

Such conventional ventilation system is operated by ventilating the fan, so when the temperature of outdoor air is very low such as winter, the temperature of the ventilating room may be drastically lowered during ventilation, which may cause air shock to the domestic animal. In addition, the summer climate is high temperature and high humidity, and in the winter, it is low temperature and low humidity, and it takes a great deal of time to maintain the temperature and environmental conditions inside the house properly.

That is, if the ventilation is performed by opening the windows, a considerable energy loss occurs due to the outflow of indoor air that has been cooled or heated during the summer or winter, and a cooling or heating cost for cooling or heating the inflow air is added In addition, there is a problem that the risk of an intruder entering the room through the open window for ventilation is increased.
