Description

Air Conditioning System

The present invention relates to a cooling system, and more particularly to a cooling system that can improve the cooling efficiency by improving the circulation structure of the cooling water to the air conditioner to perform the cooling function only by the indoor unit without the need for an outdoor unit.

In general, the air conditioner is divided into a separate type consisting of an indoor unit without a separate type separated from the indoor unit and the outdoor unit.

Here, the integrated air conditioner is composed of only an indoor unit without an outdoor unit, and is provided with an evaporator and an evaporating fan necessary for evaporation inside the indoor unit as well as a condenser, a condensing fan, and a compressor for condensation. To be performed.

However, in the conventional integrated air conditioner as described above, after installing a cooling case having a cooling water tank formed at the bottom of the indoor unit, a heat exchanger is built in the upper part of the indoor unit, and an injection plate for spraying water down the upper part of the heat exchanger. The heat exchanger is injected into the water of the cooling water tank, and the gas fed from the compressor passes through the heat exchanger, and then is supplied to the evaporator to cool the heat exchanger together with the air.

The conventional integrated air conditioner having the above configuration has the following problems.

First, the conventional integrated air conditioner has a disadvantage in that it is not neat in appearance because the supply hose is connected to the injection plate through the outside and the upper part of the cooling case when supplying the cooling water of the cooling water tank to the injection plate by the pump due to the complexity of the structure. .

Second, the conventional integrated air conditioner is not only difficult to maintain internally because the cooling case and the cooling water tank are integrally formed, but also the structure and appearance of the air conditioner and the solenoid valve installed in the cooling water tank are separately installed outside the cooling water tank. It has the disadvantage of being complicated.

Third, the conventional integrated air conditioner does not absorb the heat of the heat exchanger efficiently because air for cooling the heat exchanger is introduced into the gap between the cooling case and the cooling water tank and then discharged into the gap of the heat exchanger. There is a disadvantage that the cooling efficiency is lowered because it is discharged immediately in a poor state.

Accordingly, the present invention has been made to solve the problems described above, to eliminate the outdoor unit using the cooling portion of the water, to provide a cooling system that is easy to use integrally and exhibits excellent performance. have.

The cooling system according to the present invention for achieving the above object is connected to the gas circulation device and the second cooler in the gas circulation device installed to circulate the gas discharged by the compressor through the first cooler and the second cooler, And a gas cooling device installed to circulate water to cool the gas circulated therein, and a cooling device connected to the first cooler in the gas cooling device to circulate water to discharge cold wind to the outside. do.
