Description

Detailed Description of the Invention [Industrial Field of Application] The present invention mainly relates to a cold/hot air mixing unit for air conditioning for ships, in which air jet ports are provided at different positions and directions, and air jets are provided at different positions and directions to generate cold air, hot air, or cold air. Related to cold and hot air mixing and jet flow methods and devices for air conditioning in which mixed air is simultaneously jetted from different positions and directions from each air jetting port, and the jetting amount, temperature, etc. of each jetting port is changed according to the load. It is.

[Conventional technology]

Traditionally, double-duct type floor-mounted cold/hot air mixing units used for ship air conditioning simply blow out a mixture of cold and warm air to maintain an appropriate temperature, but the direction and temperature of the air flow are limited. In terms of cooling, air is blown in one direction, and in heating, it is blown in either - or two directions. Air at different temperatures is not blown at the same time, and the amount of air emitted from each outlet, temperature, etc. cannot be changed according to the load. It was something like that.

[Problem to be solved by the invention]

Conventional double-duct type floor-mounted cold/hot air mixing units emit a mixture of cold and warm air in a fixed direction from three air outlets, so the air can be adjusted according to the load. Since it is not possible to change the ejection volume, temperature, etc. of each ejection port, there is no function to deal with each heat load, resulting in uneven temperature distribution, and the airflow distance reaching the room is short, especially during cooling. This has the drawback that a cold air flow is generated on the floor surface, causing stagnation of cold air and stagnation of warm air in the upper part of the room during heating, resulting in the thermal environment of indoor occupants being hot and cold.

The present invention has a function to deal with each heat load, making it possible to equalize the indoor temperature distribution, extend the airflow distance into the room, and improve the stagnation of cold air on the floor during cooling and the stagnation in the upper part of the room during heating. The purpose of the present invention is to provide a cold/hot air mixing and jet flow method and its device for air conditioning that forms an effective airflow that disperses and mixes warm air, improves the thermal environment of indoor occupants, and maintains a constant state of cold head and feet. .

[Means to solve the problem]

In order to achieve the above object, in the present invention, in a double duct type floor-mounted cold/hot mixing unit in a marine air conditioner, the upper end of the unit is arranged diagonally upward in opposite directions at the front and rear ends, respectively. In addition, each air outlet is opened at the lower front of the unit, and a flow path diversion mechanism consisting of a fan-shaped damper with a guide plate for flow path conversion that works with a cold air control damper for room temperature control attached to the inside of the unit cools the air. At times, hot air is ejected from the air outlet at the lower front of the cold/hot mixing unit, and during heating, cold air is ejected from the air outlet near the front of the unit. The ejection amount and temperature are varied accordingly.

[Effect]

The flow path switching mechanism inside the double-duct type floor-standing cold/hot air mixing unit allows hot air to be emitted only from the air outlet at the bottom of the front of the unit during cooling, and cold air only from the air outlet near the front of the unit during heating. In this way, the jet volume and temperature are changed for each jet nozzle in response to the cold/hot air control damper for room temperature control, so it is possible to deal with each heat load and equalize the temperature distribution in the room. Then,
The airflow ejected in the opposite direction from the front and rear air outlets at the upper end extends the reach of the airflow inside the room, scattering and mixing the cold airflow and stagnant cold air on the floor during cooling, and the stagnant warm air at the top of the room during heating. However, the thermal environment for indoor occupants must be able to maintain a state of cold head and warm feet.

Usage example I.

This usage example is for air conditioning, and is shown in Figures 3 and 4.
This is shown in the figure.

First, the fan-shaped valve damper inner shaft 14 and the same outer shaft 14a are set using a set bin (not shown) so that the fan-shaped valve damper 13 is in the position shown in FIG. 3, and the operating knob 22 is set to the maximum cooling capacity. The cold/hot air mixture control damper 18 operates the movable sulins 22a and 22b, and fully opens the cold air population 19a.
While the hot air intake 19b is fully closed, the fan-shaped valve damper 13 with a guide plate has its fan-shaped section 13b facing down, as shown in FIG. 3A.
As shown in , the fan-shaped valve damper 13 comes into contact with the contact piece 11b at the lower end of the front opening 11 of the flow path conversion box 10 and the contact pieces 12a and 12b at the upper and lower ends of the rear opening 12, and the cold air from the flow path conversion box 10 is The cold air from the inlet 15a flows through the front opening 1.
Air is ejected into the room from the air jet lower near the front lb at the upper end of the mixing unit 1 through the upper flow path 27 near the front side, and at the same time, through the flow path opening 26a of the partition plate 26 at the upper end of the flow path conversion box 10. After that, the air is ejected toward the outer wall from the air outlet 8 near the rear of the upper end of the mixing unit 1, and 100% of the cold air is
, the cooling capacity of warm air θ% is maximized.

In this case, the jet flow toward the room from the air jet lower mainly absorbs the internal load. - The jet flow in the direction of the Manbou wall rises while absorbing the heat transfer load including the window surface to the extent possible, and diffuses down to the indoor side along the ceiling surface, so the temperature rise of the cold air from the air jet lower is suppressed. As a result, this can be prevented as much as possible, and the distance that airflow can reach indoors can be extended.

Next, when decreasing the cooling capacity, when the operating knob 22 is rotated in the direction of decreasing the cooling capacity to, for example, 30%, the cold/hot air mixture control damper 18 will control the cold air to 70% and the warm air to 30%.
0%, the movable slits 22a and 22b are operated to close a part of the cold air population 19a and open a part of the warm air population 19b, and as shown in FIG. The valve damper 13 rotates clockwise, and the fan-shaped valve damper 1
3 is the upper and lower end contact piece 11b of the front opening II of the flow path conversion box lo.
And since it is separated from the contact piece 12b at the lower end of the rear opening 12,
A hot air flow path is formed from the warm air flow path 15b, a portion of the warm air flows in, mixes with the cold air from the cold air flow path 15a at the front opening 11, passes through the front-side upper flow path 27, and reaches the upper end of the mixing unit l. Cold and hot mixed air is ejected from the air ejection lower 8 near the front surface 1b and rear surface lc toward the interior of the room and toward the outer wall. On the other hand, warm air from the lower end of the rear opening 12
It passes through the flow passage opening 24a of the partition plate 24 at the upper end, passes through the rear side upper flow passage 28, mixes with the cold air from the flow passage opening 26a of the partition plate 26, and is ejected from the rear side air outlet 8 at the upper end, and at the same time, The air is ejected from the air outlet 9 at the lower front side through the lower flow path 29 near the rear side. That is, when the operation knob 22 is turned to reduce the cooling capacity to some extent, the cold/hot air mixing control damper 18 is activated, and at the same time the supply of warm air starts, the fan-shaped valve damper 13 with a guide plate controls each air jet lower, 8.
．． The amount and properties of the air blown out from 9 change. In particular, the hot air ejected from the air outlet 9 at the lower front surface scatters and mixes the cold air stagnant on the floor, creating a thermal environment with a cold head and warm feet.

At this time, the temporary guide 16 of the fan-shaped valve damper 13 allows the jet of cold air to flow into the upper flow path 27 near the front side without any hindrance, and also allows the jet flow of the cold air to flow into the upper flow path 27 near the front side without any hindrance, and also allows the flow to flow into the front opening 1 from the warm air port 15b of the flow path conversion box 10.
This facilitates the flow of warm air to the person.

In addition, in order to further reduce the cooling capacity, when the operating knob 22 is rotated in the direction of decreasing the cooling capacity to, for example, 75%, the cold/hot air mixture control damper 18 will be configured to produce 25% cold air and 75% hot air. Movable Surin l-2 so that
2a and 22b to close most of the cold air population 19a, open most of the warm air population 19b, and close the third
As shown in FIG. C, the guide temporarily attached fan-shaped valve damper 13 further rotates clockwise, and the space between the lower ends of the front opening 11 and the rear opening 12 and the fan-shaped valve damper 136 becomes wider to cope with the increase in hot air. Therefore, the temperature of the cold air from the upper front air jet lower and the rear air jet nozzle 8 of the mixing unit 1 is higher than that in the state shown in FIG. 3B.

Furthermore, the third diagram shows the case where there is no load as the cooling condition, and the operating knob 22 is rotated 100% in the cooling capacity decreasing direction, and the cold/hot air mixing control damper 18 operates the movable suction rings 22a and 22b. , completely closed the cold air population 19a,
The hot air volume 19b is fully opened to make the cold air 0% and the hot air 100%, and the guide temporarily attached fan-shaped valve damper 13 further rotates clockwise, so that the flat plate part 13a of the fan-shaped valve damper 13 is in the front and rear openings 11.12. The hot air outlet 30 between the lower ends is divided equally, and the hot air from these public openings is distributed to the lower air outlet near the front at the upper end of the mixing unit l, the air outlet 8 near the rear, and the air outlet 9 at the lower front of the mixing unit l. It is divided and squirted.

As described above, the temperature is controlled by operating the operation knob 22 in response to changes in load. −
Operate as shown in D to maintain an appropriate temperature.

FIG. 4 shows the cold/hot air mixing ratio for the operation of the cold/hot air mixture control damper 18 and the operation of the fan-shaped valve damper 13 with a guide plate that is linked to the operation, and the air jet lowers near the front, near the rear, and at the lower front, 8. Figure 4 shows the cold air mixture ratio (%) according to the direction of ejection from Figure 4.
The solid line in the figure is cold air, the broken line is warm air, and A to D are third
For each control state shown in Figures A-D, Figure 4Y shows the air mixing ratio (%) for each blowout direction with respect to the opening degree (%) of the fan-shaped valve damper.

It shows the quantitative ratio from the front and rear air jet lowers at the upper end.

Note that the opening degrees of the dampers 24b, 25b, and 26b are adjusted depending on the installation location of the mixing unit 1, the load condition, etc., and the amount of ejection distributed in the three directions is adjusted as appropriate.

Usage example 2゜This usage example is for heating, and is shown in Figures 5 and 6.
This is shown in the figure.

During heating, the fan-shaped valve damper inner shaft 14 and the same outer shaft 14a are released from the setting pin (not shown), and the outer shaft 14a, on which the fan-shaped valve damper 13 is fixed, is set to the third position with respect to the fan-shaped valve damper inner shaft 14. 180° from the cooling position (not shown)
Turn clockwise to reset, adjust the damper 26b of the upper partition plate 26 of the flow path conversion box 10 to close or slightly open the flow path opening 26a, and set the operation knob 22 to the maximum heating capacity. The air mixing control damper 18 operates the movable slits 22a and 22b, fully closes the cold air intake 19a and fully opens the warm air intake 19b, and also closes the cold air intake 19a and fully opens the warm air intake 19b.
is the front opening 11 of the flow path diversion box 10 as shown in FIG. 5A.
It comes into contact with the contact pieces 11a and llb at the upper and lower ends and the contact piece 12a at the upper end of the rear opening 12, and the flow path conversion box lO
The warm air from the hot air outlet 15b of the rear opening 12 flows through the flow passage openings 24a of the partition plates 24, 25 at the upper and lower ends of the rear opening 12,
25a, a part passes through the rear-side upper flow passage 28 and is ejected from the rear-side air outlet 8 at the upper end toward the outer wall, and the remaining part passes through the rear-side lower flow passage 29 and reaches the front-lower air outlet 9.
The heating loss load reaches its maximum with 100% hot air and 0% cold air.

In this case, the warm air from the rear air outlet 8 has the effect of absorbing cold air from the window surface, and the opening degree of the dampers 24b and 25b at the upper and lower ends of the rear opening 12 is adjusted depending on the installation location of the mixing unit 1. The flow rate from the air outlet 8 can be determined by adjusting the flow rate passing through the passage openings 24a, 25a.

In order to reduce the heating capacity, when the operation knob 22 is rotated in the direction of decreasing the heating capacity, for example, to 30%, the cold/hot air mixing control damper 18 opens the movable slit 22a so that the cold air is 30% and the hot air is 70%. , 22b to open a part of the cold air intake 19a and close a part of the warm air intake 19b, and at the same time, the fan-shaped valve damper 13 with a guide plate rotates clockwise as shown in FIG. , leaving the contact pieces 11a, 12a at the upper end of the rear opening 11.12, the cold air population 1
5a is formed, a part of the cold air flows in, and a part of the cold air passes through the front opening 11 and the front-side upper flow path 27, and is directed indoors from the upper end front-side air jet lower of the mixing unit l. On the other hand, the remainder of the cold air mixes with the warm air from the warm air outlet 15b at the rear opening 12, and
Flow openings 24a, 25a of partition plates 24.25 at the upper and lower ends of
The cool/hot mixed air is ejected from the upper rear air outlet 8 and the lower front air outlet 9 through the rear upper and lower flow passages 28 and 29. That is, when the operating knob 22 is turned to reduce the heating capacity to some extent, the cold/hot air mixing control damper 18 is activated, and at the same time the cold air starts being supplied, the fan-shaped valve damper 13 with a guide plate controls each air jetting lower 8.
The amount and properties of the air blown out from 9 change. In particular, the cold air flow ejected from the air ejection lower air outlet near the upper front of the mixing unit 1 mixes with the warm air stagnant in the upper part of the room, and as the amount of cold air increases, the warm air scatters and mixes, creating a thermal environment that keeps your head cold and your feet warm. It is something that makes it appear.

At this time, the guide plate 16 of the fan-shaped valve damper 13 allows the jet flow of hot air to flow into the lower flow Ia29 near the rear side without any hindrance, and also facilitates the flow of cold air from the cold air outlet 15a of the flow path conversion box IO to the rear opening 12. It is something to do.

In addition, in order to further reduce the heating capacity, the operation knob 2
2 is rotated in the heating capacity decreasing direction, for example, to 75%, the cold/hot air mixing control damper 18 causes the cold air to decrease by 75% in the same manner as described above.
5%, and the movable slit 22a so that the hot air is 25%.
22b to open most of the cold air inlet 19a,
While most of the warm air population 19b is closed, the fan-shaped valve damper 13 with a guide plate further rotates clockwise as shown in FIG. 13 is widened to cope with the increase in cold air, the amount of cold air from the air jet lower air jet at the upper end of the mixing unit l and the temperature of the cold air from the air jet nozzle 8 near the rear surface are the same as in the state shown in FIG. 5B. They are both higher and lower than the average.

Furthermore, the fifth diagram shows the case where there is no load as the heating condition, and the operating knob 22 is rotated 100% in the heating capacity decreasing direction, and the cold/hot air mixing control damper 18 operates the movable slits 22a and 22b. Fully open the cold air population 19a,
The hot air intake 19b is completely closed to make the cold air 100% and the hot air 0%, and the guide plate-equipped valve damper 13 further rotates clockwise, so that the flat plate portion 13a of the fan-shaped valve damper 13 closes the front and rear openings 11. The cold air outlet 31 between the upper ends of the mixing unit 12 is equally divided, and the cold air is ejected from these public openings into three air ejection lowers near the front, near the rear, and at the bottom of the front of the upper end of the mixing unit l. Ru.

As described above, the temperature is controlled by operating the operation knob 22 in response to changes in the load, but by changing the air properties of the three types of cold air, cold/hot mixed air, and hot air and the amount of air ejected, the temperature is controlled as shown in FIG. −
Operate as shown in D to maintain an appropriate temperature.

Note that the opening degrees of the dampers 24b and 25b are adjusted depending on the installation location of the mixing unit 1, the load condition, etc., and the amount of ejection distributed in the three directions is adjusted as appropriate.

〔Effect of the invention〕

The present invention has the above-described configuration, and the air ejection lowers are provided at three locations near the upper end of the mixing unit l, near the front, near the rear, and at the bottom of the front. Therefore, each heat load can be dealt with separately, and the indoor temperature distribution can be made uniform.

In addition, during cooling, the lower air jets near the front and rear of the upper end, 8
The ejected airflow in the opposite direction of the twist prevents as much as possible the rise in the temperature of the cold air from the air ejection lower near the upper front surface, so it is possible to extend the reaching airflow.

Furthermore, the present invention blows out hot air toward the cold airflow and stagnant cold air on the floor during cooling, and blows cold air toward the warm airflow and stagnant warm air in the upper part of the room during heating, and scatters and mixes the cold air and warm air.
