Unified energy monitoring system for an apartment house using geothermal heating / cooling}

The present invention relates to an integrated energy monitoring system for geothermal air-conditioning / heating apartments, and more particularly, to an operation state of a geothermal air-conditioning / heating system including a cooling / heating temperature of a room using a geothermal air-conditioning / heating system, and a common house. Energy monitoring system for geothermal heating / cooling apartments that provides users with real-time control of metering data on electricity, gas, water and hot water usage It is about.

Most energy sources that have been used in the past have been fossil fuels such as coal, oil, and natural gas, and nuclear fuel.

However, fossil fuels generate various air pollutants during the combustion process, and nuclear fuels not only generate harmful substances such as water pollution and radioactivity, but also have limitations in reserves and thus cannot be continuously used as energy sources.

Therefore, in recent years, the development of energy to replace this has been actively conducted. Wind, solar, and geothermal energy have the advantage of reducing environmental pollution and infinite energy source, but the form of low energy density makes it possible to increase its density. Making it a key is the key.

One of such techniques is known a heat pump system that uses geothermal heat as a heat source to perform cooling / heating.

The heat pump is named for absorbing low temperature heat and bringing it to high temperature heat.The heat pump operates to use the high temperature heat emitted from the condenser for heating and hot water supply, and the cold heat from the evaporator to the heating of the building. This equipment is used for cooling and heating (hot water) at the same time. Compressor, condenser, expansion valve, evaporator and four-way valve (4-way valve).

1 is a view schematically showing a heating cycle of a heat pump using a geothermal source.

At the time of heating, the refrigerant compressed to high temperature and high pressure in the compressor is in the form of super gas, which generates hot water from the hot water generator, and then is transferred to the condenser through a switching valve, and heat with indoor air or heating exchange water in the heat exchanger attached to the condenser Exchanged. The refrigerant deprived of heat by heat exchange reaches the evaporator and is evaporated by heat from the ground in the heat exchanger attached to the evaporator, and is then sent to the compressor to repeat the cycle of high temperature and high pressure gas.

2 is a view schematically showing a cooling cycle of a heat pump using a geothermal source.

Cooling operates in opposition to the heating cycle, where the high-temperature, high-pressure supergas from the compressor is first deprived of heat to the hot water generator and then transferred to the condenser via a switching valve, which is the ground heat from the heat exchanger attached to the condenser. The heat is secondarily taken through the expansion valve, cooled to low temperature (within 7 ℃), low pressure, and then exchanged heat with hot indoor air or cooling circulating water in the evaporator. Refrigerant, which loses heat to the indoor air or cooling circulating water in the evaporator and changes to semi-gas state, is repeated in a cycle of being compressed into a high-temperature, high-pressure gas through a compressor.

The advantage of the heat pump system using the geothermal source as described above is the highest thermal efficiency among all the cooling / heating technology, can store the cooling heat or heating heat in the ground with low thermal conductivity, higher energy efficiency when cooling / heating at the same time This is a necessary technology in the current situation where energy resources are short and energy production costs are high.
