CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims priority to Korean Patent Application No. 10-2023-0050277 filed in the Korean Intellectual Property Office on Apr. 17, 2023, the disclosure of which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

The present disclosure relates to a constant temperature and humidity system, and more particularly a constant temperature and humidity system including a main body with a blower fan that draws indoor air installed on the rear side and four spaces for air movement up, down, left and right on the front side in which an outlet and damper is installed in each space to control the opening and closing of the damper, not only the constant temperature and humidity of the indoor air is achieved, but also the opening and closing or the opening rate of the air-supplying damper and the air-exhausting damper are adjusted, so that smoke can be quickly removed in case of fire to promote safety.

DISCUSSION OF RELATED ART

As many In general, a thermo-hygrostat is a device capable of maintaining an air conditioning target space at a constant temperature and humidity, which is installed in places sensitive to temperature and humidity, such as computer rooms, precision measurement rooms, engine laboratories, clean rooms in semiconductor factories, and electronic board production rooms to maintain the temperature and humidity within a certain range, thereby eliminating equipment malfunctions and variables that occur during experiments.

Meanwhile, the thermo-hygrostat includes an indoor unit having an evaporator that absorbs heat through the evaporation of a refrigerant as a main component, an outdoor unit having a compressor for compressing the refrigerant and a condenser for discharging the heat of the refrigerant as the main components, a humidifier, and a heater. An integrated thermo-hygrostat is being developed which is easy to secure installation space and can be easily installed since the indoor unit, the outdoor unit, the humidifier, and the heater are configured in one case.

A conventional integrated thermo-hygrostat includes an outdoor part and an indoor part separated by a vertical partition, a compressor and a condenser are installed in the outdoor part, and a filter, an expansion valve, an evaporator, a heater, a humidifier, an air intake damper, and a blower fan is installed in the indoor part.

Since the basic conditions of the room where the thermo-hygrostat is installed, that is, conditions such as the optimal temperature and humidity values required for the facility to be installed, do not change over time, even if a certain level of temperature and humidity is maintained continuously, purpose can be achieved.

However, since pollution sources such as fine dust may cause problems due to the introduction of outdoor air into the room, a thermo-hygrostat that allows outdoor air to flow into the room is required to automatically control whether or not to operate to allow outdoor air to flow into the room according to external environmental factors.

Meanwhile, when a fire breaks out in an indoor space where the thermo-hygrostat is installed, there is a risk of suffocation in the indoor space because the thermo-hygrostat does not have a function to remove smoke.

All-in-one thermo-hygrostat has various advantages as the indoor and outdoor units are integrated. However, there is a problem in that a separate exhaust device for discharging indoor air to the outside must be added in order to implement a smoke exhaust function that discharges indoor smoke to the outside.

Further, the damper of the present disclosure is opened and closed by a motor or the degree of flow, blocking or flow of air is controlled by adjusting the opening rate (opening degree).

In the present disclosure, heat exchange is used as a comprehensive concept including temperature change through a cooler (compressor, condenser, or evaporator) and heater for constant temperature and humidity and humidity change through a humidifier.

No outlet and damper are installed in the first partition 103a and the second partition 103b, so that air movement is not made immediately between the first upper space 110 and the second upper space 120 and between the first lower space 130 and the second lower space 140, The first upper space 110 and the second upper space 120 are connected to indoor through the upper chamber 150 from their front sides, and the first lower space 130 and the second lower space 140 are connected to indoor through the lower chamber 160 from their front sides,

As shown in FIG. 1, the present disclosure relates to a constant temperature and humidity system with the main body 100 installed on both sides of the air conditioning target space 1 from the outside to allow constant temperature and humidity of the inside and indoor air of the air conditioning target space 1 using the upper chamber 150 and the lower chamber 160 connected to the indoor, in which each main body 100 is installed with one blower fan 102, so that indoor air in the air conditioning target space 1 is introduced in the upper part and discharged in the lower part on one side, and the indoor air is introduced in the lower part and discharged in the upper part on the other side.

The upper chamber 150 and the lower chamber 160, respectively, have a wide rear side and a narrow front side toward the air conditioning target space 1.

In the present disclosure, as shown in FIG. 2, the main body 100 is divided into the front part 100a and a rear part 100b by the partition 101, and the operation of the conventional constant temperature and humidity device is performed at the rear part 100b. When indoor air in the air conditioning target space 1 is introduced through the upper chamber 150 or the lower chamber 160 by rotation of the blower fan 102 disposed below the rear part 100b, heat exchange is performed. The indoor air treated with constant temperature and humidity is discharged back to the air conditioning target space 1 through the upper chamber 150 or the lower chamber 160.

In the present disclosure, the front part 100a is a surface close to the air conditioning target space 1 in the main body 100, and faces the air conditioning target space 1 to be a combined surface of the upper chamber 150 and the lower chamber 160 through which air is directly introduced and discharged, and the rear part 100b is the opposite side of the front part 100a and is composed of a constant temperature and humidity device equipped with the blower fan 102 that draws indoor air into the body part 100.

In the front part 100a, the upper chamber 150 into which indoor air is introduced or discharged connects the first upper space part 110 and the second upper space part 120 to each other from the front side, and the lower chamber 160 connects the first lower space 130 and the second lower space 140 to each other from the front side. Further, the upper chamber 150 and the lower chamber 160, respectively, may be connected to the air conditioning target space 1 using a duct.

Meanwhile, as shown in FIG. 3, in the present disclosure, indoor air may be directly introduced, or air may be supplied indoors by the first upper space 110 and the second upper space 120, the first lower space 130 and the second lower space without the upper chamber 150 and the lower chamber 160. In this case, the dampers and outlets of the first upper space 110, the second upper space 120, the first lower space 130, and the second lower space 140, respectively, are installed as they are.

In the present disclosure, the third partition 103c disposed between the first upper space 110 and the first lower space 130, the fourth partition 103d disposed between the second upper space 120 and the second lower space 140, the first partition 103a disposed between the first upper space 110 and the second upper space 120, and the second partition 103b disposed between the first lower space 130 and the second lower space 140 are configured to divide the upper and lower or left and right spaces, and they should be able to completely separate the spaces and prevent air introduction into the rear part 100b where heat exchange for constant temperature and humidity is performed and air discharge from the rear part 100b from being mixed in the upper and lower spaces.

Spaces such as the first upper space 110, the first lower space 130, the second upper space 120, and the second lower space 140 may have a rectangular structure or a bending structure like a circle, may be changed according to the installation environment and may be communicated with each other only by the opening and closing operation of the damper installed in the respective partitions partitioning the spaces. If it is installed as a partition without a damper, there is no mutual communication. The respective spaces and the rear part 100b have the second outlet 123 through which air is introduced and the third outlet 131 into which heat-exchanged air is transported, and the remaining portions are blocked.

The respective spaces such as the first upper space 110, the first lower space 130, the second upper space 120, and the second lower space 140, are spaces separated up and down, left and right, and do not occupy the upper and lower sides at the same time and do not occupy the left and right sides at the same time. That is, the front sides of the respective spaces become the air conditioning target space 1, the upper chamber 150, or the lower chamber 160, and the rear sides directly contact the rear part 100b. The front sides of the respective spaces are in contact with the air conditioning target space 1, and the rear sides of the respective spaces are in contact with the rear part 100b where the heat exchange of the rear side is performed to control air flow between the air conditioning target space 1 and the rear part 100b that exchanges heat.

Since the upper chamber 150 and the lower chamber 160 form passages for introduction of indoor air and supply of air to the indoor space, they have the advantage of increasing the efficiency of air movement but have the disadvantage of requiring space. When there is sufficient space outside the air conditioning target space 1 or when high efficiency is required, the upper chamber 150 and the lower chamber 160 are installed and used, but when space is insufficient or when the system of the present disclosure is built inside the air conditioning target space 1, it can be used without the upper chamber 150 and the lower chamber 160.

The upper chamber 150 and the lower chamber 160 are described, but it should be noted that when the upper chamber 150 and the lower chamber 160 are excluded, the indoor and the respective spaces are directly communicated to transfer air and perform heat exchange.

Meanwhile, the second upper space 120 is provided with the first damper 121 that may open and close on the front side thereof to regulate air with the upper chamber 150, the second damper 122, which is an air-supplying damper, on the side surface thereof through which external air is introduced, and, the second outlet 123 on the rear side thereof through which the air flows with the rear part 100b. Further, with the first damper 121 of the second upper space 120 and the fourth damper 133 of the first lower space 130 opened, by the rotation of the blower pan 102, the indoor air of the air conditioning target space 1 is introduced into the second upper space 120 via the first damper 121 through the upper chamber 150, passes through the second outlet 123 on the rear side, moves to the rear part 100b of the main body 100 to undergo heat exchange, passes through the third out 131 of the first lower space 130 in which the blowing pan 102 is combined, is discharged to the lower chamber 160 through the open fourth damper 133 on the front side of the first lower space 130, and is supplied to the air conditioning target space 1.

In the first lower space 130, the fourth damper 133, which can be opened and closed is formed on the front side, the third damper 132, which is an air-exhausting damper through which external air is discharged, is formed on the side, and the third outlet 131 coupled to the blower fan 102 is formed on the rear side, which may communicate with the first upper space 110 when the fifth damper 134 installed in the third partition 103c disposed between the first upper space 110 is opened.

As described above, in the present disclosure, modes 1, 2, and 3 are performed in a top-down manner in which indoor air is introduced from the upper chamber 150 and discharged from the lower chamber 160, mode 4 is performed in a bottom-up manner in which indoor air is introduced from the lower chamber 160 and discharged from the upper chamber 150, and modes 5 and 6 are also made in a bottom-up manner.

As shown in FIG. 8, according to mode 5 of the present disclosure, with the first damper 121 and the second damper 122 of the second upper space 120, and the fourth damper 133 of the first lower space 130 closed, when the third damper 132 of the first lower space 130, the fifth damper 134 between the first upper space 110 and the first lower space 130, and the sixth damper 142 between the second upper space 120 and the second lower space 140 are opened, indoor air introduced through the lower chamber 160 is introduced into the second lower space 140, moves to the second upper space 120 through the opened sixth damper 142 in the second lower space 140, moves to the rear side 100b of the main body 100 through the second outlet 123 of the second upper space 120, undergoes heat exchange, and moves to the first lower space 130 through the blower fan 102. Further, some or all of the air discharged from the third outlet 131 of the first lower space 130 is discharged to the outside through the third damper 132. When some of the air is discharged, the rest passes through the fifth damper 134 and is supplied to the air conditioning target space 1 via the upper chamber 150 through the first outlet 111 in the first upper space 110. At this time, the amount of air discharged to the outside through the opening rate of the third damper 132 may be varied according to the fire state, and as the amount of smoke increases, it is preferable to increase the opening rate of the third damper 132 to quickly discharge the smoke.

As such, according to mode 5, the first damper 121 of the second upper space 120 is closed, so indoor air cannot be introduced into the upper chamber 150, and indoor air is introduced into the lower chamber 160 as in mode 4, undergoes heat exchange. and is discharged to the upper chamber 150. However, the third damper 132, which is an air-exhausting damper, is additionally opened so that some or all of the air is discharged to the outside through the third damper 132.

When some of the air is discharged, the rest is discharged to the air conditioning target space 1 through the upper chamber 150. Accordingly, when smoke is generated indoors in the event of a fire, the smoke can be rapidly discharged to the outside. In this way, when one main body 100 operates in mode 5, the other main body 100 operates in mode 3, so that outdoor air introduced through the main body 100 operating in mode 3 is introduced into the indoor through the lower chamber 160, and air introduced through the lower chamber 160 of the main body 100 operating in mode 5 is heat-exchanged and is discharged to the outdoor together with smoke through the third damper 132, which is an air-exhausting damper.

As shown in FIG. 9, according to mode 6 of the present disclosure, with the first damper 121 of the second upper space 120, the third damper 132 and the fourth damper 133 of the first lower space 130 closed, when the second damper 122 of the second upper space 120, the fifth damper 134 between the first upper space 110 and the first lower space 130, the sixth damper 142 between the second upper space 120 and the second lower space 140 are opened, indoor air is introduced into the second lower space 140 and moves to the second upper space 120 through the sixth damper 142, in which outdoor air is introduced through the second damper 122 of the second upper space 120, and indoor air and outdoor air are combined, move to the rear side 100b through the second outlet 123, undergo heat exchange, is discharged from the third outlet 131 through the blower fan 102, pass through the fifth damper 134 in the first lower space 130, and is discharged from the first upper space 110 to the upper chamber 150 through the first outlet 111. In this way, in mode 6, the main body 100 operates in mode 2 to introduce outdoor air and quickly discharge indoor air containing smoke in case of fire. Outdoor air is combined with indoor air in the main body 100 operating in mode 6, and smoke is discharged to the outdoor through the third damper 132 in the other main body 100 operating in mode 2.

In mode 6 of the present disclosure, in addition to mode 4, the second damper 122 of the second upper space 120 is additionally opened to introduce and supply outdoor air into the air conditioning target space 1 through the second damper 122.

Oxygen may be introduced while outdoor air is introduced in the event of a fire. However, since the present disclosure is aimed at facilitating lifesaving activities by rapidly removing smoke, outdoor air is introduced.

As described above, the constant temperature and humidity system of the present disclosure can set the mode, including an internal circulation mode for forcibly circulating indoor air, an outdoor air supply mode in which outdoor air is introduced by opening the second damper 122, which is an air-supplying damper, an air exhaust mode in which indoor air is discharged by opening the third damper 132, which is an air-exhausting damper, a ventilation mode in which the air-supplying damper and the air-exhausting damper are opened respectively, and a bottom-up mode in which the heat-exchanged air is discharged to the upper chamber 150 and a top-down mode in which heat-exchanged air is discharged to the lower chamber 160, so that it can be switched according to the situation.

As described above, as shown in FIGS. 4 to 6, according to modes 1, 2, and 3 of the present disclosure, the air that has undergone heat exchange in a top-down manner is discharged to the lower chamber 160 to warm indoor air in winter, thereby providing heating. Further, as shown in FIGS. 7 to 9, according to modes 4, 5 and 6 of the present disclosure, air with a lower temperature is discharged in a bottom-up manner to the upper side through the upper chamber 150 in indoor where the upper temperature is increased, so that it is made in a mode suitable for lowering the indoor temperature in summer.

Accordingly, the constant temperature and humidity system of the present disclosure has an effect by including the main body 100 with a blower fan 102 that draws indoor air installed on the rear side 100b and four spaces such as first and second upper spaces 110 and 120 and first and second lower spaces 130 and 140 for air movement up, down, left and right on the front side 100a in which an outlet and damper is installed in each space to control the opening and closing of the damper, not only the constant temperature and humidity of the indoor air is achieved, but also smoke can be quickly removed in case of fire to promote safety.

The present disclosure has an effect by being provided with the second damper 122, which is an air-supplying damper, for introduction of outdoor air and the third damper 132, which is an air-exhausting damper, for discharge of indoor air to switch from an air supply mode to an air exhaust mode that removes turbid indoor air and adjust the opening rate of the second damper 122 and the third damper 132 according to indoor and outdoor temperatures and air quality to control the introduction and discharge of outdoor air.

The present disclosure has a cooling effect by setting the mode in which the intake into the upper chamber 150 and the discharge from the lower chamber 160 and the mode in which the intake into the lower chamber 160 and the discharge from the upper chamber 150, respectively, so that indoor air and outdoor air are introduced or discharged appropriately according to the season to air-conditioning target space.
