Abstract

PURPOSE:To carry out an air conditioning so as not to impart uncomfortable feeling to a person by associating a heat exchanger on the users' side and a heat exchanger on the heat source side through a refrigerant piping in a refrigerating cycle. CONSTITUTION:When a compressor 5 is driven, compressed refrigerant is introduced into a heat source side heat exchanger 25, condensed to be liquefied, introduced into a side heat exchanger 3 on the users', evaporated to be vaporized, and then returned to the compressor 5. When a motor 19 is driven, a blower 17 is rotated, the air in an air zone 20 is sucked from a suction port 6 into a box 10, and cooled in a step of passing through the exchanger 3 as conditioned air. The conditioned air is introduced into an air guide 12, energized by the blower 17, then diffused and simultaneously accelerated in a step of passing through a duct 15 formed between an upper guide 11 and a lower guide 13, diffused as filmlike conditioned air flow from an outlet 16 at its end obliquely downward, and collided with a stationary surface 8, thereby forming a cylindrical air zone 20. Thus, uncomfortable feeling is not imparted to a person.

In the fourth invention, the air in the air zone enters the conditioned air generation unit by being sucked in by the blower, flows through the user side heat exchanger, becomes conditioned air, and enters the air guide. It is energized and blown out by a blower.

In the fifth invention, conditioned air is forced into the air guide by a blower.

(Example) One embodiment of the invention is shown in FIGS. 1 and 2.

In FIGS. 1 and 2, 1 is a conditioned air generation unit, 12 is an air guide, and 21 is a heat source unit.

In the cylindrical empty box 10 of the conditioned air generation unit l, an annular user-side heat exchanger 3 is disposed so as to face the intake port 6 formed in the peripheral wall 10b, and a heat exchanger 3 on the user side is disposed in the center of the top plate 10a. A hollow duct 7 rising upward is installed.

An air guide 12 is attached to the upper part of the duct 7, and a plurality of through holes 9 are bored in the middle of the air guide 12.

The air guide 12 consists of a bowl-shaped upper guide 11 and a bowl-shaped lower guide 13 disposed at a distance from the upper guide 11 at the lower part thereof. It gradually becomes narrower and curved downward. and,
A blower 17 is disposed in the center of the air guide 12, and the blower 17 is driven by a motor 19 fixed to the upper guide 11.

Inside the cylindrical container 41 of Gaien Unino) 21, there is a compressor 5, a heat source side air blower 8I24, and a motor 2 that drives the compressor 5.
2 and a heat source side heat exchanger 25 are built in.

Furthermore, an intake pipe 30 for introducing air from outside the air zone 20 into the chamber 41 and an exhaust pipe 31 for discharging air from inside the empty box 41 to the outside of the air zone 20 are attached. . This heat source unit 21 is attached to a fixed surface 8 at the lower part of the air zone 20 via casters 26.
A conditioned air generation unit 1 is installed on this heat source unit 21.

The compressor 5, the utilization side heat exchanger 3, and the heat source side heat exchanger 25 are connected via a refrigerant pipe (not shown) to constitute a refrigeration cycle.

Therefore, when operating this zone air conditioner, the motor 19
and 22 and the compressor 5 are driven.

When the compressor 5 is driven, the refrigerant compressed by the compressor 5 enters the heat source side heat exchanger 25, condenses and liquefies there, and passes through a reservoir, an expansion valve, etc. (not shown), and then flows into the user side heat exchanger 3. After being vaporized here, it is compressed via an accumulator (not shown). Return to 15.

When the motor 19 is driven, the blower 17 rotates, and the air in the air zone 20 is sucked into the empty box 10 from the intake port 6 of the conditioned air generation unit 1 and flows through the user-side heat exchanger 3. It becomes conditioned air by being cooled during the cooling process. This conditioned air passes through the duct 7 and enters the air guide 12, and after being energized by the blower 17, the air passage 1 is formed between the upper guide 11 and the lower guide 13.
5, the air is diffused and accelerated at the same time, and is blown out diagonally downward from the air outlet 16 at its tip as a film-like conditioned air flow, and collides with the fixed surface 8. and,
A cylindrical air zone 20 is formed surrounded by the membrane-like conditioned air flow, the air guide 12, and the fixed surface 8.

On the other hand, when the motor 22 is driven, the heat source side blower 24 rotates, and air outside the air zone 20 passes through the intake pipe 30, enters the empty box 41 of the heat source unit 21, and flows through the heat source side heat exchanger 25. After the temperature rises in the process, it is energized by the heat source side blower 24 and discharged to the outside of the air zone 20 through the exhaust pipe 31.

After the film-like conditioned air flow collides with the fixed surface 8, most of it flows out of the air zone 20, but a negative part flows into the air zone 20 and air-conditions the air zone 20.

By sucking the air in the air zone 20 into the duct 7 through the hole 9, the air in the air zone 20 is agitated or its circulation is promoted to equalize the temperature distribution of the air in the air zone 20 and to improve the air conditioning capacity. You can do both.

Since the heat source unit 21 is installed on the fixed surface 8 via the casters 26, the zone air conditioner and the air zone 20 formed thereby can be easily moved by moving the casters 26.

In the above embodiment, the blower 617 is arranged inside the air guide 12, but as shown in FIG. 3, it can be arranged in the center inside the conditioned air generation unit 1.

In this case, the conditioned air is forced into the air guide 12 by the blower 17, and a part of the conditioned air is blown into the air zone 20 from the through hole 9 to agitate the air in the air zone 20 and improve the temperature distribution. Equalize.

Further, in the above embodiment, the heat source side unit 21 is installed inside the air zone 20, but it can also be installed outside the air zone 21.

In the above embodiment, a case has been described in which the inside of the air zone 20 is cooled, but the inside of the air zone 20 can be heated by circulating the refrigerant in the refrigerant circuit in the opposite direction.

(Effects of the Invention) In the first invention, the heat pumped up from the air outside the air zone by the heat source side heat exchanger can be given to the air flowing through the usage side heat exchanger to produce conditioned air. This conditioned air is blown out from the air guide in the form of a film-like air flow, forming an air zone in the atmosphere, and at the same time, a portion of the air flows into the air zone and conditions the air zone, so that it can be used by people in this air zone. The person is not blown by the air stream, and the person can see through the membrane of the conditioned air stream and can freely enter and exit the air zone through the membrane of the conditioned air stream.

In the second invention, the air guide is supported by the conditioned air generation unit in the upper atmosphere of the air zone through the duct, and the conditioned air is introduced into the air guide through the inside of the duct. The conditioned air generation unit and the air guide are organically integrated via a duct, and this duct also serves as an introduction path for the conditioned air and a support member for the air guide.

In the third invention, the heat source unit, conditioned air generation unit, and air guide are organically integrated and can be moved together.

In the fourth invention, the air in the air zone is sucked into the conditioned air generation unit by the blower 1, and the air is caused to flow through the user-side heat exchanger, and the conditioned air is introduced into the air guide through the duct. It can be energized and pumped to the air guide.

In the fifth invention, the air guide can be made lighter and smaller.
