Description

[0001] The present invention relates to a heat pump system for a fish farm,

More particularly, the present invention provides a system for supplying sea water temperature to a water tank in a hot summer and increasing sea water temperature in a cold winter season to provide a system for supplying water to a water tank, In order to conserve water, sea water (referred to as water tank water) in the water tank and sea water (sea water water) that flows from the sea through the filter are appropriately mixed and then sent to the cooling apparatus. To a water tank again.

In general, fish farms are classified into sea farms and inland farms. Inland farms are relatively expensive and energy consuming than sea farms.

Especially, in order to cultivate the cold water species living in low temperature from the inland where the temperature changes according to the season, it is necessary to cool the water inside the aquarium in the summer in which the temperature is high and on the contrary, It should be heated above a certain temperature.

In this way, in order to fish inland, the temperature of the water should be controlled according to the species. In order to control the temperature of the vast water of the fish tank, a lot of energy is needed. If it is not possible to control it properly, there will be various problems such as the fish being killed.

The present inventor intends to solve such problems by using the conventional arts described below.

The cold / hot apparatus of the present application is cited below in the prior art. Accordingly, the process of the conventional heating and cooling apparatus and the heating and cooling apparatus will be described (reference to Registration No. 20-0213996)

Generally, in a hot season such as a summer season, a cooling device is used to secure a comfortable indoor environment by lowering the indoor temperature, and a heating device is used to secure a pleasant indoor environment by raising the indoor temperature in the cold season such as in the winter season .

On the other hand, air conditioners and heating devices are provided in each home, office or factory. However, in recent years, the air conditioner and the heating can be selectively used as needed. It is becoming more and more used.

In general, the above-mentioned heating / cooling apparatus has a heater for heating refrigerant in a conventional air conditioner or a separate burner, and can be selectively used according to the season. However, There is a problem that efficiency is drastically lowered in a heating process because a separate heater or a burner must be provided.

Accordingly, a cooling / heating system has been developed and used so that the efficiency of cooling and heating can be improved by utilizing the waste heat of the refrigerant discharged to the indoor unit.

The cooling / heating system has a higher utilization rate of the waste heat as described above. The cooling / heating system improves the cooling and heating performance by exchanging heat with the waste heat discharged from the indoor unit, the indoor unit installed in the room, the outdoor unit installed outside the room, A waste heat exchanger, a heating waste heat exchanger, and a plurality of valves for controlling the flow of the refrigerant according to cooling and heating

will be.

In the conventional cooling / heating system as described above, the refrigerant cooled in the outdoor unit is compressed by the compressor during the cooling operation, and then cooled again using the waste heat of the refrigerant discharged from the indoor unit in the cooling waste heat exchanging unit to maximize the temperature of the refrigerant supplied to the indoor unit To improve the cooling efficiency. When the heating operation is performed, heat is generated from the outside to the outdoor unit

And the refrigerant supplied to the compressor is reheated by using the waste heat of the refrigerant discharged from the indoor unit in the heating waste heat exchanging part and supplied to the compressor to increase the temperature of the refrigerant supplied to the compressor, so that the temperature of the refrigerant discharged from the compressor is maximized So that the heating efficiency can be improved.

The above-described technique is based on whether the room is heated or cooled depending on whether the heating operation is switched to the cooling operation or the cooling operation is switched to the heating operation (refer to Registration No. 10-0482425)

The present invention attempts to control the sea water temperature, which is a conventional problem, by using the conventional heating and cooling apparatus.

Before describing the above-described configuration, functions of the configurations listed in the system will be described, respectively.

First, the filter 10 has a filter mesh 100 therein, and the filtering agent (including the shape of a filter) charged in the filtering mesh 100 filters foreign matter contained in the sea water.

A cover 102 is provided at the upper end of the filter medium 101. The cover 103 is attached with a loop so that the net can be taken out to the outside by hooking a rope or a chain.

Secondly, the mixed water tank 30 is for mixing an appropriate amount of sea water (A) with sea water. For example, it is mixed with sea water having high water temperature in summer and water tank having low water temperature through a cooling device, Then sent to the next refrigeration unit 50 to lower the water temperature to the desired water temperature,

On the contrary, in the cold winter season, it is a mixed water tank 30 for mixing marine sea water having a low water temperature and water tank water having a high water temperature to a desired temperature in a water tank in the cold /

In this way, it is possible to reuse the hot water of the tank water (cold water in the summer season) by separately providing an addition water tank 30 to prevent energy waste.

Thirdly, the cold / hot apparatus 50 and the heat exchanger 60 are applied to the above-described conventional heat pump capable of cooling and heating. The outdoor unit 51 of the present invention is located outside the cold / warm apparatus 50, For example, when the cooling operation unit (not shown) is operated inside the cooling / heating apparatus (not shown), the inside of the cooling / heating apparatus 50 is cooled to cool the heat exchanger 60 located inside the cooling /

As a result, the temperature of the sea water (sea water mixed with sea water and sea water) moving in the heat exchanger 60 is lowered.

Conversely, when the heating operation unit (not shown) is operated, the inside of the cold / warm apparatus 50 becomes heated to raise the temperature of the heat exchanger 60 located inside the cold / As a result, the temperature of the moving seawater (sea water mixed with sea water and sea water) in the heat exchanger (60) rises.

The heat exchanger 60 is connected to one end of a plurality of pipes 61 so as to penetrate through the distribution cylinder 62 and the other end of which is connected to an inflow cylinder 62 for collecting seawater distributed to a plurality of pipes from the distribution cylinder 62 into one cylinder 63 are connected.

A plurality of vanes 64 are formed in the longitudinal direction of the pipe 61 so that the temperature generated in the cold / hot apparatus 50 is transferred (absorbed) well. That is, heat exchange is smoothly performed.

Third, the second filter 80 is a device for filtering the foreign matter generated in the water tank A.

Finally, the discharge pipe 12 is configured to surround the outer periphery of the water supply pipe line 3 in the form of a coil, and the sea water flowing into the water tank 70 and the water tank water discharged to the outside are heat exchanged .

Next, the sea water is to be charged into the water tank 70.

When the first motor pump 20 is operated, the first motor pump 20 pumps seawater seawater and charges the mixed water tank 30 via the filter 10, and at the same time, operates the third motor pump 90 Tank water (A) is pumped and charged into the mixed water tank (30) via the second filter (80).

The mixed water tank 30 is filled with the tank water and the sea water (mixed sea water and sea water mixed together). The mixed water is pumped by the second motor pump 40, The mixed seawater is connected to the motor pump 40 and sent to the heat exchanger 60 accommodated in the cooler device 50. The mixed seawater is stagnated in the heat exchanger 60 without continuously sending the mixed seawater to the heat exchanger 60, The first, second, and third motor pumps 20, 40, and 90 are continuously operated to charge the mixed water into the water tank 70 when the preset temperature is sensed by the sensor 7 '

When the temperature is lower than the set temperature, the first, second and third motor pumps 20, 40 and 90 are stopped to wait until the set temperature is reached.

This process is repeated continuously and the mixing tank is filled with mixed sea water.

However, in the case of the tank water A which can not be used due to contamination, the second valve 13 at the end of the pipe line 8 is closed and the valve 11 provided in the discharge pipe 12 is closed When the third motor pump 90 is operated after opening, the tank water is discharged to the outside through the discharge pipe 12. At this time, the filter medium may be removed from the inside of the second filter 90.

After the water tank is discharged to the outside by the above method, the third motor pump 90 is stopped, and then the first and second motor pumps 20 and 40 are operated to charge the sea water into the water tank 90.

The marine sea water filling process is charged to the water tank via the filter 10, the mixed water tank 30, and the cooling / heating unit 50 described above.
