<p>The present invention relates to a distributor unit integrally having a sub-cooler and, more specifically, to a distributor unit integrally having a sub-cooler, which has a first auxiliary expansion valve, a main expansion valve, a distributor, and a second auxiliary expansion valve. To prevent a liquid refrigerant dropping from a high position vertically from flowing into the distributor at a high pressure, the first auxiliary expansion valve on the head of an inlet pipe decompresses the refrigerant primarily, and the main expansion valve decompresses the refrigerant secondarily and drops the temperature of the refrigerant to a low temperature, so the designed calorie and flow rate of the refrigerant transferred to an indoor unit can be predetermined values, thereby improving the efficiency of the indoor unit. In addition, the sub-cooler sub-cools the refrigerant at a high temperature, and the second auxiliary expansion valve supplements the insufficient sub-cooling in the refrigerant when the refrigerant passing through the sub-cooler is recovered to the sub-cooler again through a recovery pipe, thereby improving the efficiency of the indoor unit.</p> |
