Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is applied to winter, summer, or indoors such as factories, shops, sales floors, venues, laboratories, etc., in the central and window side, the degree of solar radiation, the density of people gathering, and OA. Depending on the environmental conditions such as the heat generated by the equipment, the temperature difference is extremely high and low even in the same room, and when the cooling and heating distribution in these rooms is uncertain, the vicinity of the ceiling, the floor surface,
The present invention relates to an air conditioner for both cooling and heating, humidification, and dehumidification, which seeks to supply and distribute the air-conditioning amount and the air volume adjustment in a predetermined direction such as different directions at the same time or differently in an extremely simple and reliable manner.

[Prior Art] Conventionally, in a room where a large number of people gather, such as in an exhibition hall or a venue, the temperature difference may be remarkably different depending on the environmental condition of each room such as the gathering density, the window, and the shade.

Therefore, it is natural to expect the cooling / heating distribution according to each temperature in the room with different temperatures, but especially in the recent intelligent buildings, OA equipment and computer equipment are often used. In some cases, even if the room is winter, there is a need for cooling, but on the other hand, there is a contradiction that places such as interiors where people are located must be heated at the same time.

In terms of heating efficiency, etc., a mechanism of the type in which warm air is blown from the floor and cool air is blown from the ceiling is the most ideal mechanism for such heating, but at present, the cooling system and heating system are used. A plurality of different air conditioners were used.

However, in the installation of air conditioners with different systems, the duct arrangement becomes very complicated and complicated, and there is a concern that it may break down.Therefore, there was a problem that the installation location was restricted and the cost was high. .

For this purpose, the inventor first formed the air-blowing chamber, the cooling chamber, and the heating chamber integrally, and arranged the air-blowing passage switching and the diverted-air damper between the respective chambers so that the cold-warm air switching was adjustable. He developed a so-called cooling / heating, heating, and dehumidifying air conditioner that can easily find the optimum temperature expansion by sending air to the indoor ceiling, floor surface, or in different directions depending on the environment, and had considerable effects. .

[Problems to be Solved by the Invention] However, in the invention of the prior application, as described above, the blower chamber, the cooling chamber, the heating chamber, and the like are formed side by side in an integrated structure. Since there is a concern that the airflow branch is not smooth, some resistance will occur in the ventilation passage, and the damper operation alone will not provide sufficient airflow adjustment accuracy for the difference in air volume between the cool and warm air, and even fine adjustment operations will be required. Was extremely difficult.

The main object of the present invention is to fundamentally solve the above-mentioned drawbacks, to enable fine adjustment operation, and to expect a more complete cooling and heating supply effect.

[Means for Solving the Problem] In view of the above problems, the present invention integrally configures a heat exchange system of two systems of a cooling system and a heating system in one device, and each system in each of the above systems is provided. A ventilation passage switch and a shunt damper are provided so that each can be opened and closed freely, and the switching operation by each damper does not require installation of multiple cooling and heating equipment as in the conventional mechanism, but one of the rooms has a predetermined amount of cold air depending on the situation and environment. In addition, in the air-conditioner for both heating and cooling, which is configured so as to send cold and warm air of totally different temperature such as warm air to the other side at the same time or in different directions, the blower port of the blower in the blower path branch chamber Are opened toward the cooling chamber, and both vents of the cooling chamber and the heating chamber are opened at an angle of a substantially V-shape so that the vents of the cooling chamber and the heating chamber are opened toward the blower port of the blower. An air conditioner for cooling, heating, humidifying, and dehumidifying is provided in which an air amount adjusting damper is opened and closed in each of the air vents so that the air amount can be adjusted freely.

[Operation] The dual-purpose air conditioner for cooling and heating according to the present invention is installed indoors or outdoors, connects the outside air suction port and the return air port of the air blowing chamber to the respective air receiving portions, and connects the air blowing port of the branch chamber through the duct. Use by connecting each to the indoor air outlet.

As an example, cool air from the cooling chamber is installed on the ceiling surface.Cool air is blown to the upper layer of the room through the ceiling outlet, and warm air from one heating chamber is opened to the floor surface through the underfloor duct. Heating is provided below the room from the ventilation port.

In addition, these air conditioners are changed and adjusted by changing the air passages installed in the air passages between the chambers, dividing the flow,
By adjusting the opening / closing of the air volume adjustment damper, it is possible to supply the required amount of cold / warm air in each direction described below.

An example of the operation will be described below.

Symbols (a) (c) (d) (f) = blower passage switching, shunt dampers (b) (e) (g) (h) = passage opening / closing dampers.

A When cooling the upper part of the room: When the dampers (a) and (b) are opened, (d), (c) and (f) are closed, and (g) is opened, cool air is blown out from the ceiling air vents and mainly the upper part of the room To cool down.

When cooling the upper part of the B room and heating the floor surface ... Close the dampers (c) (f) and all other dampers (a) (b) (g) and (d) (e) (h) ( When j) is opened, the air from the air blower cools and splits the air into the heating chamber, supplying cool air to the upper part of the room and warm air to the vicinity of the floor.

In some cases, the damper (c) can be opened and closed to blow the humidified and dehumidified air into the room at the same time when the upper and lower cool and warm air is sent.

C When heating the area near the floor of the room ... Close the dampers (a) (b) (c) (f) (d) (e)
When (h) is opened, warm air flows downward to heat the indoor floor surface.

When supplying the required cooling and heating to the upper or lower layers of the D room ... By closing the dampers (b) and (h) and opening the (f) and (g), only warm air flows upwards The high places in the area are gradually heated.

When (a), (b) and (c) are closed and all the other dampers are opened, the warm air flows up and down at the same time to rapidly heat the room.

By opening and closing the damper (c) at the same time as above, it is possible to expect the humidification required at the same time as supplying warm air to the upper and lower parts of the room.

Note that it is also possible to feed humidified air to one side and dehumidified air to one side by the respective damper operations.

That is, cool air in the upper part of the room, cool air in the lower part, cool air in the upper part, warm air in the lower part, cool air in the upper part, dehumidified air in the lower part, and by fully opening the damper (j) at the outside air intake ...・ All outside air, all or part of the room, cold air at the top, outside air at the bottom, etc.Easy humidification and dehumidification air required each time due to changes in the room heating and cooling environment by adjusting the damper operation. You can ask.

F In particular, when the difference in air flow between the warm and cool air is different during heating and cooling, it is possible to perform fine adjustment feed of an arbitrary air flow by operating the air flow adjusting mechanism.
