摘要： An air-conditioner having multiple compressors includes: an indoor heat-exchanger disposed indoors and heat-exchanging indoor air; an outdoor heat-exchanger disposed outdoors and heat-exchanging a refrigerant with external air; four compressors for compressing the refrigerant to change the refrigerant to have a high temperature and high pressure; and three accumulators disposed at a suction side of the four compressors and separating the refrigerant into a gas and a liquid to supply a gaseous refrigerant to the compressors. Oil can be uniformly supplied to each compressor, thereby enhancing reliability of compressors, and since the three accumulators are small with low capacities, their installation space can be easily secured.

摘要： A method for controlling multiple compressors for use in an airconditioner is disclosed. In the airconditioner having N compressors, the method sequentially and equally operates the N compressors using a two-dimensional matrix which prevents only a specific compressor from among the N compressors from being repeatedly operated, arranges rows and columns of the two-dimensional matrix to allow all compressors to be alternately operated according to the number of operating compressors from among all compressors, and stochastically operates and stops the N compressors using the two-dimensional matrix. As a result, the method controls the N compressors to be equally operated without overlapping operation times of the N compressors, and alleviates fatigue of the compressors, resulting in equally longer lifetimes of the N compressors.

摘要： A cooling/heating apparatus using a cogeneration system is disclosed. The cooling/heating apparatus includes a discharge-side refrigerant heating unit which supplies heat of exhaust gas generated from an engine to a discharge-side refrigerant line connected to a compressor included in a cooling/heating unit, a suction-side refrigerant heating unit which supplies heat of cooling water used to cool the engine and the heat of the exhaust gas to a suction-side refrigerant line connected to the compressor, a discharge-side refrigerant temperature sensor which senses a temperature of a refrigerant passing through the discharge-side refrigerant line, and a bypass unit which bypasses the exhaust gas heat supplied to the discharge-side refrigerant line via the discharge-side refrigerant heating unit when the refrigerant temperature sensed by the discharge-side refrigerant temperature sensor is not lower than a predetermined temperature, to cut off the supply of the exhaust gas heat or to adjust an amount of the supplied exhaust gas heat. The exhaust gas heat and cooling water heat are appropriately distributed to both the suction and discharge sides of the compressor, so that it is possible to achieve an enhancement in heating performance and an enhancement in system efficiency.
