Gas Heat Pump System Using Geothermal Source

摘要

The present invention relates to a gas heat pump system using a geothermal source, to realize a small size and high efficiency gas heat pump system using a geothermal source. The present invention provides a gas engine, a compressor driven by the gas engine to circulate a refrigerant, a first four-way valve through which the refrigerant passes, an exhaust gas heat exchanger for allowing coolant to flow into the gas engine, and the exhaust gas. The outdoor unit heat exchanger for allowing the cooling water passing through the heat exchanger to pass through the gas engine and then exchanging heat with the circulating refrigerant, and in the cooling mode, the gas discharged from the gas engine to prevent the refrigerant from passing through. The heat exchanger allows the coolant passing through the engine to exchange heat with the refrigerant flowing into the compressor through the first and second three-way valves of different positions, and the outdoor unit by the circulation pump through the third three-way valve. Geothermal source that is formed in the ground during the flow into the heat exchanger to perform heat exchange An outdoor unit comprising a loop; An indoor unit consisting of an expansion valve for converting the refrigerant heat exchanged by the outdoor unit heat exchanger into a low temperature and low pressure state, and an indoor unit heat exchanger for allowing the refrigerant passing through the expansion valve to pass through the first four-way valve of the outdoor unit to be introduced into the compressor. It is configured to include. The present invention having such a configuration can realize a highly efficient system by securing a stable heat source by using a geothermal source, and by configuring the outdoor unit heat exchanger with a plate heat exchanger can perform a heat exchange function and a heat dissipation function at the same time to make the device more compact will be.
