Embodiment Construction

[0029] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0030] refer to figure 1 The above-mentioned cogeneration system comprises: a casing 1 forming an appearance; a generator 2 arranged inside the above-mentioned casing 1; a driving source arranged inside the above-mentioned casing 1 and driving the above-mentioned generator 2; Where heat is required; a heat dissipation part that dissipates heat generated by the above-mentioned driving source.

[0031] In the generator 2, the rotor is connected to the output shaft of the drive source, and electric power is generated when the output shaft rotates. The electric power generated by the above-mentioned generator 2 is directly supplied to electric power consuming equipment such as lighting or household appliances in the building through the power line, or is stored in the electric storage battery 3 provided in the above-mentioned cabinet 1 and then supplied from t...

Abstract

In a combined heat and power generation system and a control method thereof of the present invention, hot water flow is determined according to the temperature in a water storage tank and water flow cycled in a hot water supplying portion, and any one of hot water supplying or heat radiating is selected. At present, the time of no hot water flow determinied by a no-flow signal is set less than the time of hot water flow determined by a flow signal. Therefore, no hot water flow is determined within shorter time, and the convertion from hot water supplying to the water heat radiating can be rapidly realized. In addition, under the conditon that the convertion from hot water supplying to the water heat radiating can be rapidly realized, the temperature excessive rising of the hot fluid cycled in the inner part of the system can be prevented. Thereby the temperature of the storage tank, that is water supplying target temperature, can be set as higher temperature.

Description

technical field [0001] The invention relates to a co-generation system and a control method thereof, in particular to a co-generation system and a control method thereof which can realize switching from hot water supply to heat dissipation more quickly and accurately. Background technique [0002] In general, a cogeneration system is a system that produces both electricity and heat from one energy source. The above-mentioned cogeneration system includes a generator and a drive source for driving the generator. An engine or the like can be used as the above-mentioned driving source. The power generated by the above-mentioned generator is supplied to the place where the power is needed. [0003] The heat generated by the above-mentioned driving source includes a water storage tank that stores warm water. The heat generated by the above-mentioned driving source is supplied to the above-mentioned water storage tank, so that the temperature of the warm water stored in the abov...
