Patent number: 7543631Abstract: An exhaust gas heat exchanger for a cogeneration system is disclosed. In the exhaust gas heat exchanger, a heat exchanger cover is arranged around a heat exchanger body such that a primary heat medium passage, through which a heat medium passes, is defined between the heat exchanger cover and the heat exchanger body. In the heat exchanger body, a heat medium tube forming a secondary heat medium passage, through which the heat medium emerging from the primary heat medium passage passes, is arranged. Accordingly, the heat medium primarily absorbs heat from the exhaust gas while passing through the primary heat medium passage, and then secondarily absorbs heat from the exhaust gas while passing through the secondary heat medium passage. As a result, an enhancement in heat exchanging efficiency is achieved.Type: GrantFiled: October 17, 2005Date of Patent: June 9, 2009Assignee: LG Electronics Inc.Inventors: Cheol Min Kim, Cheol Soo Ko, Sim Bok Ha, Baik Young Chung

Patent number: 7350365Abstract: A method for controlling a cogeneration system is disclosed. The control method determines whether or not the operation load or power load of an air conditioner corresponds to a load requiring driving of a generator, controls the generator to operate when it is determined that the operation load of the air conditioner corresponds to the generator driving load, controls the air conditioner to operate using electric power generated from the generator when the generator operates normally, and controls the air conditioner to operate using commercial electric power when the operation load of the air conditioner is not the generator driving load or when the generator operates abnormally. Accordingly, there are advantages in terms of economy and safety.Type: GrantFiled: October 17, 2005Date of Patent: April 1, 2008Assignee: LG Electronics Inc.Inventors: Cheol Min Kim, Cheol Soo Ko, Sim Bok Ha, Baik Young Chung
