JPH061125B2 - Individual air conditioner - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to an individual air conditioner configured to ensure a comfortable vertical temperature distribution even when one room having an existing air conditioner is finely divided by partition or the like. .

<< Conventional Technology >> Conventional cooling and heating air conditioners generally supply either warm air or cold air to the air-conditioned room space, and the direct control target for adjusting the thermal environment is the room. The whole is directly controlled.

Therefore, when the room is cooled or heated, the room temperature tends to be higher in the upper part and lower in the lower part due to the difference in air density. On the other hand, it is said that people living in the room have a low temperature on the ceiling side and a high temperature on the floor side, which is a comfortable environment, as it is called so-called head cold foot fever. The convection of air is kept constant to make the room temperature as uniform as possible. However, it has also been reported that the higher the supply air flow velocity, the more people will feel the discomfort, and the convection flow velocity of the indoor air is limited and generally low.

<< Problems to be Solved by the Invention >> The air-conditioned room space of the conventional cooling and heating air conditioner is divided into partitions and partitions, which is remarkable in a recent office room. Therefore, the convection in the room is obstructed, and the heat generated from the office equipment and the body temperature are also exerted, which is contrary to the ideal of the vertical temperature distribution in which the lower part is relatively warm.

The present invention has been made in view of the above described circumstances, and an object thereof is to provide an individual air conditioner suitable for easily realizing at least partially a vertical temperature distribution that causes head cold foot heat.

<Means for Solving the Problem> In order to achieve the above object, the individual air conditioner of the present invention is provided with a partitioning panel such as a partition having an air passage through which cool and warm air passes, and an evaporator of an air heat source heat pump. Is installed in the air passage of the panel, and the condenser is installed below the outside of the panel.

<Operation> Conditioned air from the main air conditioner passes through the air passage for partitioning. Since the evaporator absorbs heat from this conditioned air, the temperature of the conditioned air in the main air conditioner will drop somewhat during either heating or cooling. On the contrary, heat is generated from the condenser installed at a lower position outside the partition or the like, and the air near the floor is warmed.

«Examples» Hereinafter, preferred examples of the present invention will be described in detail with reference to the drawings.

Each of the figures shows a room to which the individual air conditioner of the present invention is applied.

In FIG. 1, a double floor type air conditioning duct 3 provided on a floor slab 1a of a room R surrounded by a slab 1 and a wall 2
There is a partition 5 having an air passage 4 communicating therewith.

For cooling and heating of the room R, cold air or warm air that has undergone heat exchange with a main air conditioner (not shown) passes through the air conditioning duct 3 under the floor, and further passes through the air passage 4 in the partition 5 and from the outlet 6 at the top of the partition 5 to the room R. It is carried out by blowing in.

Further, a small air heat source heat pump is installed near the base of the partition 5, only the evaporator 8 of the heat pump is housed in the air passage 4, and the compressor 9 and the condenser 10 are outside the partition 5.

That is, the heat in the air passage 4 is forcibly transferred to the outside of the partition 5 and the heat in the condenser 10 is transferred to the fan 1.
At 1, the conditioned air is blown onto the floor surface, and conditioned air having a temperature higher than the conditioned temperature from the blowout opening 6 above the partition 5 is supplied from near the floor.

A case where the heat of the condenser 10 is taken out by the heat radiation panel 12 is shown in FIG. This is partition 5 and desk surface 1
When the three are integrated, forced ventilation by a fan or the like is not sensationally preferable, so the heat radiation panel 12 is attached below the desk surface 13.

As a result, the bottom of the desk surface 13 becomes warmer than the top of the desk surface 13 and the point that the lower limbs are too cold during cooling is eliminated. During heating, the floor surface is kept warmer than above the room R.

<Effect> As described in detail above, according to the configuration of the present invention, the partition panel for partition or the like is provided with the air passage through which the cool and warm air passes, so even if the room is finely divided, the cold and warm air can be separated from the partition. Can be taken out. Therefore, it is possible to eliminate the stay of the conditioned air.

Also, put the heat pump evaporator in the air passage,
Since the condenser is placed outside the partition or the like, the upper part is cooled not only during cooling but also during heating, and the vicinity of the floor is warmed, and an ideal vertical temperature distribution can be obtained.

Since the temperature near the floor is raised by the heat pump,
It consumes less power and has the effect of providing a comfortable sensible temperature for each partition.
