OUTDOOR UNIT INTEGRATED TYPE PORTABLE AIR CONDITIONER HAVING AIR CIRCULATION PIPE, PARTICULARLY REGARDING TO IMPROVING THE COOLING PERFORMANCE BY UNIFORMLY CONTACTING ALL AIR SUCKED INTO CONDENSATION CHAMBER WITH SURFACE OF CONDENSER

摘要

PURPOSE: An outdoor unit integrated type portable air conditioner having an air circulation pipe is provided to improve the cooling performance by uniformly contacting all air sucked into a condensation chamber with a surface of a condenser and securing a wide area of the condenser. CONSTITUTION: A casing(1) has a condensation chamber(5) having an air suction port and an air discharge port, and an evaporation chamber(7). An air circulation pipe(13) is installed in the condensation chamber and is communicated with the air discharge port. A condensation fan(23) sucks air into the condensation chamber and discharges the sucked air to the air discharge port through the air circulation pipe. A compressor(15) is installed at a bottom of the casing, and compresses a refrigerant. Condensers(17a) are installed in the air circulation pipe and converts vapor refrigerant compressed in the compressor into liquid refrigerant of high pressure. An expansion valve drops a pressure of the liquid refrigerant. An evaporator(19) is installed in the evaporation chamber and vaporizes the liquid refrigerant of low pressure.
