Abstract
Description
- The present invention relates to an indoor air conditioner disposed inside of a room, and more specifically relates to an indoor air conditioner having upward and side outlets.
- In cooling or heating indoor air by an indoor air conditioner, various attempts have been made to provide the entire indoor air with uniform temperature distribution. However, they have not yet reached to the level of sufficient satisfaction.
- One conventional example of the above-stated attempts is described in Japanese Patent Laid-Open Publication No.
2000-346392 - In
EP-A-1 014 011 there is disclosed an airflow control method and airflow controller for an air conditioner indoor unit capable of executing air conditioning so that indoor temperature distribution becomes uniform without any sense of airflow during heating operation. A turbofan is provided that has an axis extending in an anteroposterior direction and blows air taken in from a front surface side radially outwardly with respect to an axis inside a casing and a heat exchanger disposed on the front surface side of the turbofan inside the casing. The casing is provided with outlet ports for blowing air from the turbofan in the vertical direction and the horizontal direction. During the heating operation, a control signal is output by a flap control section to an upper flap stepping motor and a left-hand flap stepping motor so as to narrow the openings of the upper, right-hand and left-hand flaps and make the opening of the lower flap wider than the openings of the upper, right-hand and left-hand flaps. - According to one aspect of the present invention there is provided an indoor air conditioner having an upward outlet formed on a top face of a main unit and a side outlet formed on at least one side face of the main unit, the indoor air conditioner comprising: air volume control means for controlling blow of air so that a blown-off air volume from the upward outlet is larger than a blown-off air volume from the side outlet in a cooling operation, characterized in that: a ratio of the blown-off air volume from the upward outlet to the blown-off air volume from the side outlet is set to 2:1 to 4:1 in a case where a side blown-off air is blown-off from the side outlet on one of side faces of the main unit.
- According to another aspect of the present invention there is provided an indoor air conditioner having an upward outlet formed on a top face of a main unit and a side outlet formed on a side face of the main unit, the indoor air conditioner comprising: air volume control means for controlling blow of air so that a blown-off air volume from the side outlet is equal to or larger than a blown-off air volume from an upward outlet in a heating operation, characterized in that: a ratio of the blown-off air volume from the upward outlet to the blown-off air volume from the side outlet is set to 1:2 to 1:1 in a case where a side blown-off air is blown-off from the side outlet on one of side faces of the main unit.
- The present invention takes a new standpoint of controlling the volume of air blown off from the indoor air conditioner into upward and side directions so as to solve a problem of temperature nonuniformity during indoor cooling and heating operations, and thus to provide an air-conditioned environment as cozy as possible.
- As shown in
Fig. 1 , the indoor air conditioner of the present invention is composed ofair outlets upper face 12 and one or bothside faces upward outlet 22 and from theside outlets -
Swing flaps 32 and shutters 33 for increasing or decreasing air passage areas at the air outlets are used as means for controlling the air volume. - The present invention is directed to improve nonuniformity of temperature distribution in indoor cooling and heating operations controlling the volume of air blown off from the upward and side outlets of the indoor air conditioner so as to provide an air-conditioned environment as cozy as possible. For indicating a degree of conformability of air conditioning environment, there are used two indexes: PMV (Predicted Mean Vote) index and PPD (Predicted Percentage of Dissatisfied) index, both of which are designated in the ISO standards.
- The PMV index has four elements regarding environment: temperature, humidity, airflow and radiation, and two elements regarding human: metabolic quantity and clothing quantity. Values of the PMV index corresponds to thermal senses. The PMV value +3 is "hot", +2 is "warm", +1 is "warmish", ±0 is "neither hot nor cold", -1 is "coolish", -2 is "cool", and -3 is "cold". In the ISO standards, it is recommended that the PMV index falls within "the range of -0.5 to +0.5." Therefore, in the present invention, "the range of -0.5 to +0.5" has been adopted as a preferable PMV index range.
- The PPD index is defined as "an index for quantitatively predicting the percentage of people who feel thermally dissatisfied during staying in a given environment." The ISO standards state that the PPD index is desirably 10% or less for coziness in a residential environment of human beings.
- In the present invention, a later-described "PMV cozy zone occupancy" is used in a cooling operation when setting a ratio of an upward blown-off air volume to a side blown-off air volume. Also, a "vertical temperature difference" is used in a cooling operation when setting a blown-off angle of side air.
- In a heating operation, a "PPD index" is used when setting a ratio of an upward blown-off air volume to a side blown-off air volume and setting a blown-off angle of side air.
- It is noted that the "PMV cozy zone occupancy" is defined as "a ratio of the zone (cozy zone) where the PMV index is in the range of -0.5 to +0.5 to an other residual zone in an air-conditioned space (indoor space)".
- Under the above-stated condition, description will be given of control of upward and side blown-off air quantities in the indoor air conditioner of the present invention.

Fig. 2 is a graph for setting the ratio of an upward blown-off air volume to a side blown-off air volume in cooling operation, and shows the relation between the upward blown-off air volume and the PMV cozy zone occupancy when the side blown-off air volume is set to 1. - The graph indicates that the PMV cozy zone occupancy rises while the ratio of the upward blown-off air volume to the side blown-off air volume shifts from 1:1 to 4:1, and that thereafter the PMV cozy zone occupancy decreases.
- In the present invention, the range from 2:1 to 4:1 of the blown-off air volume ratio has been adopted as a preferable range, as a result of comparison between the above-stated and the PMV cozy zone occupancy of 90% or more in radiator air conditioning operation.
- This is explained with reference to examples shown in the drawings. As shown in
Figs. 3 and4 , in the cooling operation, air volume control means is operated such that the blown-off air volume UC from an upward outlet is larger than blown-off air volume SC1, SC2 from one or both of side outlets. - In the case where side blown-off air is blown-off only from a side outlet in a side face (
Fig. 3 ), the ratio (air volume ratio) of a blown-off air volume UC from the upward outlet to a blown-off air volume SC1 or SC2 from a side outlet is preferably in the range of UC:SC1 (or SC2) = 2:1 to 4:1. It is noted thatreference numeral 5 inFig. 3 denotes a side wall face. - In the case where side blown-off air S1, S2 are blown-off from
side outlets Fig. 4 ), the preferable ratio range is SC1:UC:SC2 = 1:2:1 to 1:4:1. -
Fig. 5 is a graph for setting a blown-off angle of side blown-off air in the cooling operation, and shows the relation between change of a side blown-off angle and difference of vertical temperature in air-conditioned space. - In the present invention, the range within 1.5 °C (the range where the side blown-off angle is not smaller than -20 degree) has been adopted as a preferable range of the vertical temperature difference in air-conditioned space during cooling operation.
- In the cooling operation, in order to prevent excessive fall of air temperature in the vicinity of the floor face, it is preferable for the air volume control means to have a function of controlling blown-off air so that air blown-off from the

- In the present invention, the range in the ratio of the upward blown-off air volume to the side blown-off air volume from 1:1 to 1:2 (PPD index value of approximately 6.7 or lower) has been adopted as a preferable range, from a viewpoint of making the PPD index value better than the PPD index value (total mean value of 7.11) in radiator heating operation.
- This is explained with reference to examples shown in the drawings. As shown in
Figs. 7 and8 , in the heating operation, the air volume control means is operated such that blown-off air volume SW1, SW2 from side outlet(s) is equal to or larger than the blown-off air volume UW from the upward outlet. - The ratio (air volume ratio) of the blown-off air volume UW from the upward outlet to the blown-off air volume SW1, SW2 from the side outlet (s), UW:SW1 (or SW2), is preferably in the range of 1:2 to 1:1 in the case where side blown-off air is blown-off from a side outlet on one side face (
Fig. 7 ). In the case where the side outlets are disposed on the left and right sides (Fig. 8 ), the ratio (air volume ratio) of a blown-off air volume SW1 from a left-side outlet to a blown-off air volume UW from an upward outlet and to a blown-off air volume SW2 from a right-side outlet is preferably ranged from 2:1:2 to 1:1:1. -
Fig. 9 is a graph for setting a blown-off angle of side blown-off air in the heating operation, and shows the relation between the blown-off angle of side blown-off air S1, S2 and the PPD index. - According to the graph, the PPD index value becomes larger as the blown-off angle of the side blown-off air S1, S2 increases, and the PPD index value exceeds approximately 6.7 when the blown-off angle is larger than the horizontal (0°).
- In the present invention, in view of this PPD index value, the horizontal (0°) is set to the upper limit of the blown-off angle of the side blown-off air S1, S2, so that the blown-off angle does not become larger than the horizontal.
