[Industrial application field]

This invention provides comfort for each individual living in each office in an office building. Concerning personal air conditioning equipment that saves energy while providing suitability.

0002

[Conventional technology]

An individual air conditioning system that supplies cold or warm air to each individual in the office. Various proposals have been made, but with the exception of electric heaters and combustion type heaters, there are no separately manufactured heaters. Cool or warm air is guided through ducts to areas where individuals live, and then directed toward each individual's body. Many of them are designed to blow out air individually. In other words, air conditioning is applied only to specific living areas indoors. Air that has been heated or cooled by a machine is blown through a duct. This duck Many of the facilities in the country utilize the space under the floor, and for this purpose various improvements have been made to the floor structure. is proposed.

0003 Also, partitions used to separate offices can be used as air blowing members. In order to cope with the partial load increase due to the heat generation of OA equipment and Some proposals have also been made, such as installing a cold air outlet on the stand or desk of the A-equipment.

[Problem that the idea aims to solve]

In the conventional individual air conditioning system as mentioned above, an air conditioner is needed to cover the air conditioning load. Whether this air conditioner uses an air heat source or a water heat source, heat source equipment is required. be. Once installed, air is supplied through ducts to the air conditioner and individual living areas. Since installed air conditioners usually cannot be moved freely, The connecting duct will also not be able to move freely on the air conditioner side. In addition, air conditioners Normally, drain piping is required, and this drain processing must be performed separately. death Therefore, residents can freely operate the air conditioner and duct system as they wish. It is not possible to move to In offices where air conditioning occurs, there may be restrictions on changing the layout of the office. There is a problem.

[0005] As a heating device that can be moved freely, hot air heaters that use electricity or gas as a heat source are recommended. Although there are heaters and panels, the problem is that they are useless for cooling. in the office Due to internally generated heat, there is a strong demand for personal air conditioning for cooling. Also, It doesn't look good to have such heating equipment in the office when it's needed.

[0006] For this reason, both cold air and warm air are blown out when needed in each person's living area. Moreover, like the heating equipment, it can be moved freely anywhere and its existence is There is a need for a personal cold/hot air generator that does not disturb office work or appearance. It was getting worse. At that time, even though it is for personal use, cold and hot air is supplied to multiple people individually. It is also required that it be a multi-type that can blow out water and an energy-saving type. It will be done. The present invention aims to solve the above-mentioned problems and satisfy the above-mentioned requirements. It is something that

The refrigerant compressed by the compressor 22 is condensed in the second air heat exchanger 21, which is a condenser. The air is compressed and radiates heat to the air, and after being throttled by the expansion valve 23, the first air heat exchanger 20, which is an evaporator, A heat pump that evaporates, removes heat from the air, cools the air, and returns it to the compressor 22. form a group. These heat exchangers 20 and 21 are connected to the indoor primary air through the air intake 24. Conditioned air is taken in and passed through the heat exchanger 20, which is an evaporator. The wind passes through the connection port 7 to the cold air duct 14 of the wind tunnel 4, and also to the heat exchanger 21 which is a condenser. The warm air passed through and heated is sent to the hot air duct 15 of the wind tunnel 4 through the connection port 8. be caught. 24 and 25 indicate blowers for blowing these air. Note that this When operating the heat pump, the air to be ventilated in the heat exchanger 20, which is an evaporator, control so that the heat transfer surface is not cooled to a temperature below the dew point of the This causes heat No condensate is generated in the exchanger 20, so no condensate piping is required. Ru. In addition, the rotation speed of the compressor 22 and blowers 24 and 25 is controlled by a well-known inverter. However, depending on the usage situation of each person, the operating capacity and air volume of the heat pump equipment should be adjusted according to the usage situation of each person. Control it to just a few minutes. During operation of the heat pump equipment, the heat exchanger 20 or In some cases, it is not particularly necessary to blow out the air that has passed through 21 from the outlet of wind tunnel 4. However, in consideration of this, appropriate preliminary openings should be made to allow air to flow into the room from an appropriate location. (not shown) is provided in the air passage after passing through these heat exchangers.

[Effect of the idea]

The proposed equipment with the above configuration has a drainless air system in the primary air-conditioned office. The main body of the air source heat pump device is installed movably, and indoor air is taken into it. The primary air conditioner produces only the required amount of cold or warm air. By using the equipment of this invention, the difference between This reduces the load on secondary air conditioning, resulting in significant energy savings. In addition, air heat source Although the main body of the air pump device is an air conditioner capable of cooling and heating, it is not a normal air conditioner. It has the advantage of being able to be installed anywhere in the room, which is not possible with conventional equipment, such as heating equipment. There is a point. It also has a shape that can coexist with an office desk, so it looks good and its presence is great. It also avoids the possibility of the current location interfering with changes to the layout, and saves space. At the same time, each person can freely enjoy air conditioning according to their preference without bothering others. In addition, It is possible to blow cold air to the face and chest and hot air to the feet at the same time, so it is not necessary to cool the air conditioner. This will prevent your feet from getting cold even when you are in the room, and if necessary, it will also prevent your feet from getting cold. Or you can freely take out just the warm air.
