The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "electrically connected" with another part in between . Also, when an element is referred to as "comprising ", it means that it can include other elements as well, without departing from the other elements unless specifically stated otherwise.

1 is a configuration diagram of a temperature holding system according to an embodiment of the present invention. 1, the temperature holding system includes a temperature holding device 10, a window 20 of a building connected to one end of the temperature holding device 10, and a server room to be subjected to temperature maintenance, Includes indoor space. However, since the temperature holding device 10, the window 20 and the indoor space shown in FIG. 1 are merely illustrated for convenience of explanation, the configuration of the temperature holding system of the present invention is limited to those shown in FIG. It is not interpreted.

The indoor space is a space that is subject to temperature maintenance. For example, it is a room where box-like structures are installed intensively, or a server room is concentrated in a narrow space, A server room that can not go outside and can be rolled up inside. However, the indoor space to be subjected to the temperature maintenance is not limited to those exemplified above.

The window (20) is a door to the wall or roof of the building, which can be viewed through the window (20) and can receive air and light.

The temperature holding device 10 can measure the outdoor temperature. For example, the temperature holding device 10 can be provided with a temperature sensor inside at least one of the windows 20, and can measure the outdoor temperature through each of the temperature sensors. In other words, the temperature holding device 10 can measure the outdoor temperature of 1.3 占 폚 through any one of the plurality of temperature sensors.

The temperature holding device 10 can control the operation of the at least one fan motor based on the measured temperature. For example, the temperature holding device 10 can receive the operating temperature at which the fan motor is to be operated in advance, and operate the fan motor when the measured temperature is lower than the pre-input operating temperature. More specifically, the temperature holding apparatus 10 can operate at least one fan motor when the input operating temperature is 21 占 폚 and the measured outdoor temperature is 1.3 占 폚.

The temperature holding device 10 can draw air from the outside through the fan motor and let the air that is drawn in from the outside through the duct into the room. At this time, one end of the duct is connected to the window 20 which is in contact with the outside, and the fan motor can introduce outdoor air into the duct through the window.

The temperature holding device 10 can be provided with a fan motor and a temperature sensor in the window 20 so that cooling can be performed in an indoor space such as a room using external cold air due to temperature variation, , It can be more effective in high-rise buildings such as buildings where cool winds and cold temperatures occur throughout the year, or in geographical locations where wind power can be used.

For example, the fan motor 101 may serve as an air intake fan for introducing outdoor air into the room, and the fan motor 101 may introduce cold outdoor air through the window 20 into the room.

The duct 102 can introduce the air that is drawn in from the outside into the indoor space. At this time, one end of the duct 102 may be connected to the window 20 which is in contact with the outside of the room. For example, the duct 102 may be directly connected to the window 20 by covering the interior of the building outer wall window 20 with a lid.

The duct 102 may further include an air filter that removes impurities from air that is sucked from the outside. For example, the air filter may further include an air filter for removing impurities in the air introduced through the duct 102 to introduce clean air into the room. Such an air filter can be detached and detached, so that it can be separated and cleaned from time to time.

The duct 102 may further include a heat insulating material inside the duct 102 to prevent dew condensation inside the duct 102 or the fan motor 101. [ In addition, an auxiliary door which can be opened is provided on the duct 102, and the auxiliary door provided is closed to prevent the duct 102 from being used in the summer or the like.

The temperature sensor 103 measures the outdoor temperature. For example, the temperature sensor 103 is installed in the duct 102 surrounding the outer-wall window 20, and it can be measured that the outdoor temperature is 1.3 ° C. The temperature sensor 103 can prevent the temperature from being erroneously measured for reasons such as malaise or freezing even when the outdoor temperature falls below 0 占 폚 by using the temperature sensor of the alloy material.

The control unit 104 controls the operation of the at least one fan motor 101 based on the measured temperature. In this case, the control unit 104 receives the operating temperature at which the fan motor 101 operates, and can operate at least one fan motor 101 when the measured temperature is lower than the input operating temperature. For example, when the fan motor 101 is operated at a temperature of 21 DEG C and the temperature measured through the temperature sensor 103 is 1.3 DEG C lower than the operating temperature, (101) can be operated.

Also, the maximum temperature of the room is 29.5 ℃, the lowest temperature is 25.8 ℃, and the temperature difference is 2.8 ℃. Table 1 shows the monthly temperature of Seoul in 2012, and Table 2 shows the monthly temperature measured through the temperature sensor 103 of any room.

The control unit 104 can set the temperature at which the external air can be introduced to be set to 24.7 ° C based on the average holding temperature of one of the equipment rooms and the temperature difference of the equipment room and the control unit 104 controls the minimum temperature of the equipment room, The appropriate temperature at which the fan motor 101 operates can be set to 21 DEG C by using the temperature difference at night. The control unit 104 can operate the fan motor 101 when the temperature measured through the temperature sensor 103 is equal to or lower than the set temperature.

The auxiliary door installed in the duct 102 may be closed to prevent outdoor air from flowing in April to September when the maximum temperature of Seoul is 24.7 ° C. or higher.

The controller 104 can operate the fan motor 101 automatically or manually to reduce the risk.

The controller 104 senses the danger of overheating or burning of the fan motor 101 and can operate the protective relay in response to the sensed danger. For example, the control unit 104 may prevent overheating and burnout of the plurality of fan motors 101 by using a protection relay.

Although not shown in the drawings, the temperature holding device 10 may further include an exhaust fan motor.

The exhaust fan motor can exhaust the indoor air to the outside. At this time, the temperature sensor 103 can be installed in the indoor space to measure the indoor temperature. When the indoor temperature measured based on the operating temperature of the exhaust fan motor is higher than the operating temperature of the exhaust fan motor , At least one exhaust fan motor can be operated. For example, the exhaust fan motor may be installed in the equipment room or the server room to exhaust the air in the equipment room or the server room outside the equipment room. More specifically, the control unit 104 can set the operating temperature of the exhaust fan motor to 31.5 ° C in consideration of the average holding temperature of the equipment room and the temperature difference between the upper and lower parts of the equipment room. The control unit 104 can operate the exhaust fan motor to exhaust the air inside the equipment room to the outside of the equipment room when the measured room temperature through the temperature sensor 103 installed in the equipment room is higher than the set operating temperature.
