Description

[Detailed Description of the Invention] << Industrial Application Field >> The present invention relates to a desk with an air conditioning unit capable of maintaining an ideal temperature condition around the desk affected by the temperature distribution of guides and the flow of air.

<< Conventional Technology >> Conventional cooling and heating air conditioners generally supply either hot 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 there is a limit to the convection flow velocity of indoor air, which is generally gentle.

In recent years, air-conditioning equipment using an underfloor space generally tends to overcool the vicinity of the floor during cooling.

<< Problems to be solved by the invention >> The air-conditioned room space by the conventional cooling and heating air-conditioning system is divided into partitions and partitions, as is typical of office rooms. Therefore, the convection in the room is blocked,
The fever from the office equipment and the body temperature, etc., also acted, and the result was significantly contrary to the ideal of the vertical temperature distribution in which the lower part was relatively warm.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a desk with an air conditioning unit suitable for easily realizing at least partially a vertical temperature distribution which causes head cold foot heat.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the desk with an air conditioning unit of the present invention surrounds the desk surface of the desk, and a panel having a ventilation passage that goes upward from below the desk surface, and the desk. A heat pump unit in which an evaporator, a condenser, a compressor, and a blower are integrally housed in a size that can be stored below the surface, the blower introduces external air into the heat pump unit, and the heat pump unit is installed in the heat pump unit. To form a ventilation path for sending to the ventilation path of the panel,
The condenser comprises a heat dissipation panel facing the front open surface of the heat pump unit. Further, when the desk and the heat pump unit are separately manufactured, the air passage can be freely attached to and detached from the air passage of the panel so as not to be affected by the size change of the desk, and the heat pump unit includes the panel. It was possible to mount and dismount it on the desk.

<Operation> The air sent from the blower of the heat pump unit to the ventilation passage of the panel absorbs heat by the evaporator in the unit, and the temperature is somewhat lower. On the contrary, the heat radiation panel of the condenser under the desk heats the air near the floor.

<< Embodiment >> Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

The desk 1 of the present invention comprises a panel 2 having a ventilation passage and a heat pump unit 4 which can be stored under the desk surface 3,
FIG. 1 shows these arrangements. That is, it is a side view of the desk 1 with both panels removed, in which the front panel is the panel 2 and the heat pump unit 4 is installed under the desk surface 3. The heat pump unit 4 is thin so as not to interfere with the feet of the person using the desk 1, and the heat radiation surface for the heat radiation panel 6 of the condenser 5 is exposed on the front surface thereof. Since only the temperature distribution around the person who uses the desk 1 is adjusted, the heat capacity can be small, and the desk can be easily made thin.

FIG. 2 shows a vertical cross section of FIG. A through hole 7 that crosses the panel 2 is provided in the lower portion of the panel 2, and the diameter thereof may be such that the heat pump unit 4 can exchange heat and supply the amount of air to be blown out. In addition, it is the middle of the panel 2 and the desk surface 3
An air passage 8 is provided from the lower position through the inside of the panel 2 to the front surface of the top. The opening through the front surface of the top of the ventilation passage 8 is used as an air outlet 9, and a louver for turning is appropriately installed inside.

The heat pump unit 4 has a ventilation path 10 having openings that can be connected to the through holes 7 and the ventilation path 8 provided above and below,
A cooling coil 12 connected to the evaporator 11 is housed at an intermediate position, and a blower 13 facing the upper opening is housed.

When the blower 13 is in operation, the outside air is taken in from the through holes 7 and brought into contact with the cooling coil 12, the cooling air passes through the ventilation passage 8 in the panel 2, and exits from the air outlet 9 at the top thereof. On the other hand, the heat of the condenser 5 is released from the heat dissipation panel 6.

<< Effects >> The present invention has the above-described configuration in detail, and thus has the following effects.

That is, since there is a heat radiation panel on the front of the heat pump unit under the desk surface, the sensible temperature of the legs is warm, while on the other hand, cool air is blown from above the panel, so the air temperature near the head is lower and cooler than near the floor surface.

Since the temperature distribution above and below the desk is only slightly changed in this way, the power consumption is extremely low and the size can be considerably reduced. This is advantageous in terms of installation space and transportation.

Furthermore, the ventilation path of the heat pump unit can be freely attached to and removed from the ventilation path of the panel, and the heat pump unit itself can be moved, so it can flexibly respond to changes in the size of the desk, and the mounting position of the heat pump and the desk etc. You can easily decide. Further, since the present invention comprises such a panel and a heat pump unit, it can be easily attached to an existing desk and can easily realize an ideal vertical temperature distribution that produces cold head heat.
