Description

Cooling device of cooling water for an air conditioning unit

The present invention relates to a cooling water chiller for a water-cooled air conditioner, and more particularly, after cooling the refrigerant (freon gas) passing through the condenser by introducing condensate generated from the evaporator and external supply water connected to the tap water (that is, the refrigerant). By cooling it, it means heated water.) It can be recycled to maximize water saving effect, stabilize cooling, and achieve high efficiency.

As is well known, a water-cooled air conditioner composed of only an indoor unit refers to a structure for cooling a refrigerant (freon gas) as water, and the water used as the cooling water generally uses water supplied from the outside and condensate generated in the evaporator during cooling. .

However, in the conventional water-cooled air conditioner, the configuration of cooling the refrigerant is a condenser that condenses the refrigerant in a predetermined case, and the condensate generated from the evaporator and the cooling water mixed with the external supply water are sprayed or sprayed on the condenser where the refrigerant circulates. It is composed of a main form, and once the sprinkled water is collected in a collecting tank while cooling the Freon gas passing through the inside of the condenser, it adopts a configuration in which it is re-pumped with cooling water for cooling the condenser.

However, the above cooling method of the refrigerant will inevitably follow the following problems.

That is, since the refrigerant passing through the condenser is very high temperature, the sprayed or sprayed cooling water is heated in an instant compared to the cooling rate of the refrigerant, and as it is heated, the cooling water is easily evaporated, so that the consumption of water increases and the cooling water collected in the collection tank is increased. Since the refrigerant must be re-supplied before being cooled, the cooling efficiency of the refrigerant was greatly reduced.

In addition, the water cooling + air cooling method which sucks external air and cools the condenser by air together with water by using a slightly different method from the above is adopted, but in this case, the cooling efficiency of the refrigerant is slightly increased while the evaporation amount of the cooling water is quite large. The problem is that the volume does not meet the expectations, but the efficiency increases.

In addition, the condenser is built in a predetermined case in addition to the above configuration, and the cooling water is filled in the case so that a certain amount of water is circulated at all times, but this configuration also increases the cooling water temperature rapidly, but the refrigerant cooling efficiency is not much higher than expected. There was a problem.

Of course, if the continuous supply of external feed water is used to cool the condenser and discharge the heated cooling water from the condenser to the outside, the cooling efficiency of the refrigerant can be greatly increased. The installation line is not neat because the discharge line must be present together with the supply line.

In other words, a conventional water-cooled air conditioner using only an indoor unit can maintain the efficiency of the air conditioner only when the coolant cools down the coolant and then lowers the temperature of the coolant itself. In the conventional configuration, the condenser cooling structure for cooling the coolant is very high. Inefficient construction, and there is no device that lowers the temperature of the heated cold water, the function of the air conditioner could not be properly exercised.

Therefore, the present invention was invented in view of the above-mentioned conventional problems.

In particular, in cooling the refrigerant with the cooling water, it is to provide a cooling water cooling device that enables the continuous reuse of the cooling water to achieve a maximum water saving effect, stabilization of cooling and high efficiency.
