Abstract:
An air conditioner includes a heat exchanger including a refrigerant tube, a fin assembly, and a fan assembly located at an upper portion of the heat exchanger. The heat exchanger includes a first heat exchanger adjacent to the fan assembly and a second heat exchanger under the first heat exchanger. A density of a fin assembly at the first heat exchanger is larger than that of a fin assembly at the second heat exchanger. The heat exchanger may include a plurality of layers with a refrigerant introduced into each of inlet pipes of the heat exchanger flowing evenly at each of the layers. The refrigerant to be discharged to each of outlet pipes is discharged at the same temperature.
Abstract:
A cooling and heating control method of a multi type air conditioner in which a target pressure of a compressor is adjusted based on conditions of respective indoor units so as to reduce power consumption is provided. The cooling control method includes determining the indoor unit desired to execute power saving control, judging whether or not a difference between a temperature of a space in which the indoor unit desired to execute power saving control is located and a set temperature of the indoor unit is less than a reference value, raising a target evaporation temperature of the indoor unit upon judging that the difference is less than the reference value, comparing an evaporation temperature of the indoor unit with the raised target evaporation temperature, and raising an evaporation pressure of a compressor, when the evaporation temperature of the indoor unit is lower than the raised target evaporation temperature.

The air conditioner includes a compressor; a sensor for measuring the compressors state configured to detect compressor state information that includes at least one of a pressure value and a saturation temperature of the compressor; and a controller configured to control air flow on the side of an indoor unit by comparing the compressor state information measured from the sensor and a threshold.
Abstract:
In an air-conditioning system, a gaseous refrigerant remaining in a reservoir can be discharged from the reservoir even when a cooling operation has started and the reservoir is being filled with a liquid refrigerant. Therefore, the reservoir can be filled with the liquid refrigerant at a faster speed.
