Abstract

A cogeneration system is disclosed which includes a generator, a drive source for driving the generator, a waste heat supplying heat exchanger for enhancing the heating performance of a heat pump type air conditioner, an auxiliary heating heat exchanger using the waste heat of the drive source as a heat source for heating indoor air, and a regeneration heat supplying heat exchanger using the waste heat of the drive source as a heat source for regenerating a dehumidifier. The cogeneration system can use the waste heat of the drive source for diverse purposes in accordance with the indoor environment, and can have a maximal efficiency.

Description

technical field [0001] The present invention relates to a combined heat and power system, and more particularly to a combined heat and power system in which waste heat from a driving source for driving a generator can be used to enhance heating performance of a heat pump type air conditioner, and It can be used as a heat source for regenerating a dehumidifier, and can also be used to assist the heating operation of a heat pump type air conditioner. Background technique [0002] figure 1 A schematic diagram of a conventional combined heat and power system is shown. [0003] like figure 1 As shown, the traditional cogeneration system includes: a generator 2, which generates electricity; a driving source 10, which works to drive the generator 2, and the driving source 10 generates waste heat during operation, and the driving source 10 is, for example, an engine (The driving source 10 is hereinafter referred to as an "engine"); an exhaust heat recovery device 20 which recover...
