Description

System for cooling and ventilating apartment house

The present invention relates to a cooling and ventilation system, in particular, can be installed in a large-scale apartment, circulating the water to perform the cooling and save energy by using the midnight power, and simultaneously perform the ventilation to the outside air The present invention relates to an air conditioning and ventilation system for apartments, which prevents heat loss due to direct ventilation and requires less installation area and thus does not need to change floor heights.

In recent years, the most important factor in choosing a house is the comfort of the room, which means that the cooling and ventilation system of the room is the most important factor.

In general, more than a certain size of office building is using the ice heat storage air conditioning system as a cooling system. Ice heat storage air conditioning is a method of making ice using low-cost late-night power, and then thawing the ice during the day to form cold air to circulate in each room of the building to cool.

The cooling method as described above has the advantage that not only the power cost is reduced by using the midnight power, but also it can prevent the overload caused by the excessive use of power during peak hours in the summer, and can be easily applied to changes due to facility expansion and change. .

However, because the system circulates air, which is gas for cooling, ducts should be used, and due to the nature of the fluid, more energy is consumed than circulating water, and above all, ducts must be installed to all rooms to supply air to each room. There is a disadvantage that the investment equipment costs initially increase, such as the height of the floor, it is not used in buildings for general residential.

In general, in a residential building such as an apartment, heating is performed by a central heating method, but in cooling, air conditioning is usually provided by individually installing individual air conditioners.

Therefore, if air conditioners are separately installed in each house for cooling in residential buildings such as apartments, as described above, there is a high possibility of power failure due to an overload caused by an increase in the use of midsummer, and the cost of power personally increases. In addition, such a cooling method has been pointed out as a big problem in terms of efficient use of energy, such as more power plants have to be produced according to the power demand.

In addition, in such a residential building, the heating or cooling system does not have a function of ventilation, and passive ventilation is performed by opening and closing of windows and doors that are not completely enclosed, which always generates a considerable amount of heat loss. It means that there is.

In addition, it is sometimes necessary to ventilate the windows to open them, which results in greater heat losses, and more energy is needed to compensate for these heat losses, resulting in the unpleasant feeling of sudden cold air from ventilation. In addition, there was a problem of wasting a lot of energy.

The present invention is to solve the above-mentioned shortcomings, can be installed throughout the large-scale apartment, can save energy, prevent heat loss by direct ventilation to the outside air, and need a large central supply duct It does not need to change the floor height because it occupies a small installation area and provides an air conditioning and ventilation system for apartments that can reduce the cost of equipment.

The present invention system ice heat storage air conditioning system, the circulation system for air conditioning and heating of each house in the apartment, each module of the ventilation system and the indoor heat exchange system into one, and circulates water, not air to perform cooling, Is achieved by using.
