Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an energy integrated control system using a gas heat pump system having a power generating function,

The present invention relates to an energy integrated control system including a gas engine driven heat pump system (GHP), and more particularly to a gas heat pump system, a solar generator system, and an external power system The integrated management of the power supplied by the system, the integrated management of information on each of the gas heat pump system, the solar generator system and the energy storage system (ESS), the individual control of each system, To an energy integration control system and method using a gas heat pump system having a power generation function capable of monitoring information on each system and integrated information of the systems.

Generally, a gas heat pump system is a system that can perform a cooling or heating operation by providing a cooling cycle and a heating cycle with gas as fuel.

Typically, a gas heat pump system is a number of pumps that exist to circulate refrigerant, cooling water, and the like within a system. A plurality of electric valves, electronic devices, and the like. Such a power supply is supplied from an external power facility at a separate power cost.

In addition, the gas heat pump system can be interlocked with the hot water supply to provide warm hot water.

A common hot water supply apparatus produces hot water by using a heat source obtained by heat exchange between a refrigerant and a predetermined heat storage medium when the gas heat pump system operates according to a cooling cycle and a heating cycle.

Therefore, the conventional gas heat pump system generates hot water by using the heat source generated in the heating / cooling cycle, and thus there is a problem that the thermal efficiency is lowered.

To solve these problems, Korean Patent Registration No. 10-1714900 [Gas Heat Pump System] (hereinafter referred to as "Prior Art") discloses a gas heat pump system that generates hot water using waste heat of an engine.

However, this prior art requires additional external power for driving pumps, valves, electronic devices, and the like, so that there is a problem of paying an additional electric power fee.

In addition, the prior art has a problem in that the efficiency is inferior because the waste heat of the gas engine can not be utilized by distinguishing the cooling mode and the heating mode.

To solve these problems, studies have been made to generate electric power by using a gas engine of a gas heat pump system.

However, such a study has not suggested a method for managing the electric power generated from the gas heat pump system, and thus it has been difficult to efficiently use the generated electric power.

In addition, the conventional gas heat pump system uses the power of the gas engine only for compressor driving, which is inefficient.
