Cogeneration system and method for controlling the same

Abstract

The invention discloses a heat and power cogeneration system and its control method, wherein the heat and power cogeneration system includes: a heat and power cogeneration device for providing at least one of electricity and heat to an air conditioner; and a heat and power cogeneration device controller for It is used to control the operation of the combined heat and power device according to the operation signal from the air conditioner. The combined heat and power system and its control method have the advantage of being easy to operate the combined heat and power device because the operation of the combined heat and power device can be controlled according to the operation signal of the air conditioner, and the combined heat and power system and its control method have the advantages of using the air conditioner and The interconnection between cogeneration units enables optimal use of the electricity produced by the cogeneration units.

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 and a control method thereof. Electricity and waste heat recovered from the engine are used in the air conditioner, thereby increasing the efficiency of the system. Background technique [0002] A combined heat and power system is generally a system capable of producing both electricity and heat from a single energy source. Electricity generated by the combined heat and power system is used in home appliances such as various household lighting devices, heat pump type air conditioners, and the heat source generated by the combined heat and power system is used for hot water supply, warm water, and the like. [0003] figure 1 is a block diagram schematically showing a combined heat and power system according to the prior art. [0004] Such as figure 1 As shown, the combined heat and power system according to the prior art inclu...

AI Technical Summary

Problems solved by technology

[0010] However, the cogeneration system according to the prior art has such a problem that only the electricity generated by the generator 2 is supplied to the air conditioner 6, and the waste heat recovered by the engine 4 is only used for hot water supply, warm water, etc. in the heat demand point, so that the efficiency of the system cannot be maximized
