    • 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.
    • 公开了一种使用热电联产系统的冷却/加热装置。 冷却/加热装置包括:排出侧制冷剂加热单元,其将从发动机产生的排气的热量提供给与包括在冷却/加热单元中的压缩机连接的排出侧制冷剂管线;吸入侧制冷剂加热单元, 将用于将发动机冷却的冷却水和排气的热量供给到与压缩机连接的吸入侧制冷剂管路的排出侧制冷剂温度传感器,其检测通过排出侧制冷剂的制冷剂的温度 并且当由排出侧制冷剂温度传感器感测到的制冷剂温度不低于预定温度时,绕过通过排出侧制冷剂加热单元供应到排出侧制冷剂管线的废气热量的旁路单元, 切断废气供给的热量,或者调节供给废气的热量。 排气热和冷却水的热量适当地分配到压缩机的吸入侧和排出侧,从而可以实现加热性能的提高和系统效率的提高。
