Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a geothermal heat pump for cooling a geothermal heat pump,

The present invention relates to a geothermal heat pump hot water supply and heating system for directly cooling a geothermal heat pump using geothermal heat. More specifically, it is possible to simultaneously perform cooling, heating, and hot water operation using a single device, To a geothermal heat pump heating / cooling hot water system in which cooling is directly performed by an underground heat that can reduce cooling operation power.

In recent years, the importance and importance of renewable energy has been increasing due to depletion of fossil fuels and global warming caused by the use of fossil fuels.

Renewable energy refers to energy created in nature, such as solar energy, wind energy, hydro energy, geothermal energy, biomass energy, tidal energy, and wave energy.

On the other hand, most of the renewable energy is deformation of solar energy, so its amount is limited and it is highly affected by solar energy, but geothermal energy is not highly affected by solar energy.

Therefore, the research and development on the construction of the heating and cooling system using the geothermal heat pump in the near future is also being continuously carried out.

However, in the case of the conventional technology known up to now, power is required to drive the compressor and the circulation pump due to the structural limitations thereof, so there is a problem in that power is consumed during cooling, heating, and hot water operation.

Also, in a facility requiring air conditioning, hot water supply or heating and cooling, the conventional technology can not selectively apply cooling, heating, or hot water supply.

For example, in a facility where a heat source and a heat pump are commonly used, cooling and heating are separately requested for each load zone, the conventional technology can not reflect this.

In addition, in the case of the prior art, due to the structural limitations, the compressor driving power is used even in the cooling operation, and thus the energy cost is inevitably increased. In addition, in order to apply the hot water supply, the hot water supply equipment is separately installed, .

As a result, the conventional technology has become a complicated system, and the increase of the construction cost has been a factor to delay the recovery of the investment cost, which has hindered the diffusion of the geothermal heating / cooling system, which is a new / renewable energy with high efficiency.

On the other hand, in order to reduce the cooling operation cost, there has been attempted to supply the geothermal heat directly to the load device in order to perform the cooling, but it is insufficient to utilize the enormous heat source in the ground effectively and there is no means to assist the heat source. And it is known that the actual effect is insufficient. Therefore, a new and advanced system that can solve these problems is needed.

The form of the heat source replenishment shown in Figs. 3 and 4 is in the form of a low-layer heat source replenishment. However, it is also possible that the heat source heat exchanger E-1 replenishes the heat source side or the heat source heat exchanger E-2 replenishes the load side as shown in FIG. 5 as shown in FIG. 5. In FIGS. 5 and 6, May be in the form of a heat source supplement.

The reason why the separate heat exchanger, that is, the heat source heat exchanger (E-1, E-2) is applied as shown in FIGS. 5 and 6 is to prevent damage to the heat source pipe and reduce the construction cost in the case of a high-rise building.

3, the present invention shares a common heat source, that is, the geothermal heat exchanger 110. However, in the case of a load zone or a complex residential facility, the geothermal heat pump 120 for each household is applied Cooling and / or heating.

In addition, the supply of hot water is performed by applying a hot water storage tank 130 as a tank for storing a hot water without applying a separate hot water supply heat pump (not shown) to the hot water heat storage tank 120, The hot water is stored, and the supply of heat is performed by indirect heat exchange with hot water.

The hot water storage tank 130 can be used for the hot water supply and the heating water A similar effect can be achieved if applied in reverse. That is, the heating heat can be stored and the hot water can be supplied to the heat exchange water.

On the other hand, the supply of cooling can be achieved by circulating the geothermal heat directly to the load side. The cold heat required for the cooling and cooling is obtained by performing the heating and the hot water supply to the geothermal heat pump 120 on the side of the geothermal heat pump 120 and the cold heat stored in the ground through the evaporator, The cooling can be achieved only by operating the heat source / cold water circulation pump 161, for example.

However, in contrast to the prior art, the prior art has a problem that the season conversion mode (4WAY V / V) is essential for solving the cooling and heating hot water supply, while the present invention can be solved by constructing a simple system without a separate season conversion mode . This is expected to make a significant contribution to the improvement in the durability and efficiency of the geothermal heat pump 120.

Hereinafter, a system flow chart in various modes will be briefly described with reference to Figs. 7 and 11. Fig.

For reference, in the case of Figs. 7 and 11, the system flow is shown by a dark arrow, and the portions covered by the arrows are forcibly omitted for the sake of convenience.

7 is a system flow chart in the heating and hot-water supply mode.

The system controller 200 regards the system controller 200 as a case where the heating or the hot water supply load is generated when the value sensed by the hot water temperature sensor 132 is equal to or lower than a predetermined setting value and the system controller 200 controls the cooling / 211 to control the heat source / cold water pressurizing pump 162, the hot water heat storage pump 170, and the geothermal heat pump 120 to operate.

When heating is required, the system controller 200 can control the heating circulation pump 180 to operate, and hot water for heating can be hot water in the hot water storage tank 130.

The cold water generated by heating circulates in the ground and is supplied to the cooling operation zone if necessary. At this time, since there is no operation of the geothermal heat pump 120 for cooling, no power is required.
