1 is a configuration diagram of a conventional automatic water temperature control system, including a pump 5 for introducing and discharging sea water; A boiler (1) for heating and discharging the introduced seawater to a predetermined temperature while passing the hot water heat exchanger (2) according to whether the seawater open / close valve (6) provided at one side of the discharge pipe of the pump (5) is opened; A chiller (3) cooling the seawater introduced by the pump (5) to a predetermined temperature while passing through the cold water heat exchanger (4), and discharging it according to whether the cold water open / close valve (7) provided on one side is opened; A tank (8) for temporarily storing hot water and cold water discharged from the boiler (1) and the freezer (3), respectively; It comprises a control unit (9) for controlling the opening and closing of the opening and closing valves (6, 7) by sensing the temperature of the hot or cold water introduced into the tank (8).

Since the conventional automatic water temperature control system configured as described above uses a method of directly heating or cooling the room temperature seawater flowing in accordance with the user's required temperature, the user's required temperature may be changed from hot water to cold water, or cold water to hot water. At the time, the cold water heat exchanger 4 cools the seawater introduced in the heated state, or the hot water heat exchanger 2 heats the seawater introduced in the cooled state. Therefore, excessive heat load is applied to the boiler 1 and / or the freezer 2 to increase the work to be performed.

In addition, the greater the change in the required temperature, the longer it takes to be able to obtain the hot water or cold water of the required temperature, the higher the fuel costs, as well as a large amount of water to be introduced in a short time There was a problem that can not be heated or cooled to the desired temperature due to room temperature seawater.

Therefore, in order to solve the above problems, a water temperature automatic control system as shown in FIG. 2 has been proposed.

A boiler 20 which is heated and discharged at a temperature; A chiller 22 which cools and discharges the seawater introduced by the cold water pump 26 to a predetermined temperature while passing the cold water heat exchanger 23; A valve unit (30) for controlling a mixing ratio of hot water discharged from the boiler (20) or cold water discharged from the freezer (22) and room temperature seawater introduced and discharged by a room temperature seawater pump (25); And sensing the temperature of the mixed hot water or the mixed cold water properly mixed by the valve unit 30, and controlling the valve unit 30 according to a result of comparing the detected temperature with a user-specified temperature. Or the controller 50 which adjusts the mixing ratio between cold water and room temperature seawater to match the temperature of the mixed water with the user's desired temperature.

In the conventional automatic water temperature control system of FIG. 2, the hot water or cold water heated and cooled to a predetermined temperature and room temperature seawater are mixed, but the mixing ratio can be adjusted so that the boiler or the cooler is continuously operated in accordance with the change of the user's required temperature. The present invention relates to an automatic water temperature control system using a room temperature seawater mixing method so that a desired temperature of seawater can be obtained, and can extend the life of a boiler or a freezer, and more precisely control the temperature of hot or cold water. Using only a boiler and a freezer, there is an advantage in that it is possible to obtain hot or cold water at various temperatures simultaneously.

However, such a conventional automatic water temperature control system generates a lot of heat of condensation during operation of the refrigerator 22, which accelerates the corrosion of peripheral devices due to the heat of condensation, harmful environment composition due to propagation of harmful microorganisms, and energy. There was a problem such as waste.

The present invention has been made to solve the conventional problems as described above, the object is to provide a bioenvironmental control system having a water temperature control function to be able to recycle the waste heat treated condensation heat as an energy source for hot water production. .

The cooler 110 allows the refrigerant which is easy to evaporate to be circulated, and the refrigerant is circulated alternately by changing from liquid to gas and gas to liquid by the evaporator and condenser, and from the surroundings at the time of vaporization of the refrigerant. By cooling the room temperature seawater in the first heat exchanger 120 by using an endothermic phenomenon, the room temperature seawater is heated in the second heat exchanger 130 by the heat of condensation generated during the condensation of the refrigerant. .

The second heat exchanger 130 is to circulate the circulating water made of general water, the circulating water is heated by the condensation heat generated when condensation of the refrigerant, by the heat exchange between the heated circulating water and the room temperature seawater The seawater is heated so that it is converted to hot water.

In addition, as shown in FIG. 4, in the second heat exchanger 130, a temperature sensor 190 and the temperature sensor 190 are included in a circulation path of the circulation water flowing into the condenser side of the cooler 110. A bypass valve 192 for opening and closing the circulation path and a circulation pump 194 for smoothly circulating the circulation water according to the temperature sensed by the first and second circulation valves; The cooling tower 196 is connected to the bypass valve 192 in parallel. The circulating water is selectively introduced into the cooling tower 196 according to whether the bypass valve 192 is opened or closed and is cooled and discharged.

Next, the operation of the present invention will be described.

First, the room temperature seawater introduced by the seawater pump 100 passes through the first heat exchanger 120, the second heat exchanger 130, and a separate transfer pipe under the control of a valve (not shown). , The room temperature seawater introduced into the first heat exchanger 120 is taken out by the evaporator of the cooler 110 and converted into cold water, and the water is extracted. The room temperature seawater introduced into the second heat exchanger 130 is Warmed by the condenser of the cooler 110 is converted into hot water and then discharged.

Heat of condensation generated from the condenser of the cooler 110 is generally about 30 ° C. to 35 ° C., and the circulating water circulating through the second heat exchanger 130 is heated by the condensation heat, and the warmed circulating water is the 2 Heat-exchanged with the room temperature seawater introduced into the heat exchanger 130 to make the room temperature seawater into hot water, which is then converted back to the room temperature circulating water and fed back to the condenser side. As described above, the circulating water of the second heat exchanger 130 is circulated while being heated by heat exchange with the condenser and circulated while being cooled by room temperature seawater and heat exchange, thereby allowing the condensation heat of the condenser to be recycled as an energy source for producing hot water. .

However, since the amount of room temperature seawater flowing into the second heat exchanger 130 is controlled in accordance with the required amount of hot water, circulation when circulating the second heat exchanger 130 is required when hot water is not required or when a small amount is required. The temperature of the water is only warmed by the heat of condensation, so that the temperature reduction effect due to heat exchange with the room temperature seawater is hardly generated, and thus, the heat of condensation cannot be transferred to the circulating water. Therefore, the condenser that does not exchange heat may cause a condensation overload and a problem that the cooler 110 is stopped.

Therefore, in order to prevent the above problem, the temperature sensor 190 senses the temperature of the circulating water, and when the detected temperature of the circulating water is higher than the preset temperature by controlling the bypass valve 192 Close the circuit. When the bypass valve 192 is closed, the circulating water flows into the cooling tower 196, and the circulating water introduced into the cooling tower 196 is sufficiently cooled to a condensation proper temperature, and then, of the cooler 110. By being discharged to the condenser side, sufficient heat exchange between the condenser and the circulating water is achieved.

Meanwhile, the hot water introduced from the second heat exchanger 130 to the third heat exchanger 140 is additionally heated by the heater 150 and the boiler 160 as needed, and then is discharged. And the operation of the boiler 160 to selectively operate the hot water primarily heated in the second heat exchanger 130, if necessary additional heating if necessary.

Finally, cold water introduced through the first heat exchanger 120, hot water introduced through the second heat exchanger 130 and the third heat exchanger 140, and room temperature seawater introduced separately. After controlling the mixing ratio of the through the controller 170, the controller 180 through the controller 180 based on the temperature of the mixed water mixed by the controller 170 and the user's designated temperature based on the discharge water Adjust the temperature of the mixed water.

As described in detail above, according to the biological environment control system having a water temperature control function according to the present invention, it is possible to save energy by recycling the condensation heat as an energy source for producing hot water, and to accelerate corrosion and harmfulness of peripheral devices due to the condensation heat. There is an effect of preventing the harmful environment due to the breeding of microorganisms and the like.
