DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 and FIG. 2 show an embodiment of an integrated air conditioner for wall installation according to the present invention. This air conditioner is returned to the upper end portion (upper end surface in the illustrated example) of a flat box-shaped casing 1 that is thin on the side. An air intake port 2 and an exhaust port 3 are formed, and an outer air intake port 4 and an air supply port 5 are formed at a lower end portion (lower end surface in the illustrated example) of the casing 1, and a refrigerant circulation circuit 13 is formed in the casing 1. The return air intake 2 and the air supply port 5 are connected in communication, and the vertical air supply air passage A provided with the evaporator 6, the reheater 7, and the air supply fan 8, and the outside air intake 4 and the exhaust port 3 are connected. A vertical exhaust air passage B that is connected and provided with a condenser 9 and an exhaust fan 10, and a damper mechanism 12 that controls the return air amount of the supply air passage A and the outside air amount of the exhaust air passage B. I have.
[0006]
Between the supply air supply passage A and the exhaust air supply passage B, a first series passage C that leads the return air taken in from the return air intake 2 to the condenser 9 and the outside air taken in from the outside air intake 4 are evaporators. And a second hose 11 that is also movable to the blowing position is connected to the air supply port 5. The hose 11 is carried to an arbitrary place in the room to air-condition the entire room or to locally air-condition the room. The exhaust port 3 and the outside air intake port 4 are communicated with the outside through a duct or a gargle. Solid and dotted white arrows indicate the wind direction.
[0007]
The refrigerant circulation circuit 13 is formed by connecting an evaporator 6, a condenser 9, a reheater 7, a compressor 14, a liquid receiver (not shown), an expansion valve, a forward / reverse switching valve in the refrigerant circulation direction, and the like. The heat absorption and heat dissipation of the evaporator 6 and the condenser 9 are configured to be switchable. The reheater 7 is provided leeward of the evaporator 6, and a part of the refrigerant (hot gas) flowing through the condenser 9 is bypassed to the reheater 7 so as to be freely cooled, dehumidified, and reheated. The fin tubes of the evaporator 6, the condenser 9, and the reheater 7 are preferably elliptical tubes, but may be circular tubes.
[0008]
The supply air passage A and the exhaust air passage B are arranged in parallel, the evaporator 6, the reheater 7, and the condenser 9 are adjacent to each other, and the suction type air supply fan 8 is placed downstream of the evaporator 6 and the reheater 7. In addition, a suction exhaust fan 10 is provided on the lee of the condenser 9 and components of the refrigerant circulation circuit 13 such as a compressor 14 and a liquid receiver are provided on the wind of the condenser 9 to make effective use of space and compactness. Plan In addition, arrangement | positioning of the evaporator 6, the reheater 7, the air supply fan 8, the condenser 9, the exhaust fan 10, the compressor 14, etc. can also be made into things other than the example of a figure. The refrigerant circuit 13 can be provided integrally with a frame (not shown) so that it can be taken out and stored in the casing 1, and only the refrigerant circuit 13 can be taken out from the casing 1 without removing the entire casing. Refrigerant recovery work and maintenance can be performed easily, and installation and storage are not time-consuming. Further, by replacing only the refrigerant circulation circuit 13, it is possible to reduce the cost at the time of renewal.
[0009]
The casing 1 is provided with a damper 15 for controlling the amount of return air from the return air inlet 2 to the evaporator 6 and a damper 16 for controlling the amount of outside air from the outside air inlet 4 to the condenser 9 to provide a damper mechanism. 12 and performs air volume control by various operation control devices. Each of the dampers 15 and 16 may have any structure in which only the full-close / full-open switching or the arbitrary air volume can be varied. Although not shown in the figure, for example, a damper for controlling the return air flow rate from the return air intake 2 to the condenser 9 and a damper for controlling the outside air flow rate from the outside air intake 4 to the evaporator 6 are provided. It is good also as a damper mechanism which controls the air volume control of the external air and return air of the ventilation path A, and the air volume control of the external air and return air of the exhaust ventilation path B.
[0010]
An example of the operation of this air conditioner will be described. In the ventilation / cooling / heating operation, the return air from the return air inlet 2 and the outside air from the outside air inlet 4 are mixed at a predetermined ratio, and heat is exchanged by the evaporator 6 to obtain cold air or warm air. Is supplied from the intake port 5, and at the same time, the circulating refrigerant in the condenser 9 is heat-exchanged with the return air from the return air intake 2 and the outside air from the outside air intake 4 to absorb heat or dissipate heat and recover exhaust heat. A predetermined amount of room air is exhausted from the exhaust port 3 to the outside.
[0011]
In the supercooling / dehumidification / reheating operation, the air in the supply air passage A is supercooled / dehumidified by the evaporator 2 and then reheated by the reheater 7 to supply so-called dry air. The circulating refrigerant in the condenser 9 is heat exchanged with air and exhausted outdoors. At this time, a separate heating source is not required for reheating, and the condenser load is reduced to save energy. The air to be supercooled / dehumidified may be only return air, only outside air, or mixed air of return air and outside air. In the ventilation operation and the outside air cooling operation, the compressor 14 is stopped, the damper 15 and the damper 16 are fully closed, only the outside air is supplied into the room, and only the return air is exhausted outside. In the example shown in the figure, the air conditioner is installed on the indoor side of the wall, but it can also be installed on the outdoor side. Further, the number of air supply ports 5 and hoses 11 can be increased or decreased.
[0012]
3 and 4 show another embodiment, in which a return air intake 2 is formed at the upper end of a flat box-like casing 1 which is thin on the side, and an outside air intake 4 and an air supply port 5 are formed at the lower end of the casing 1. And the exhaust air outlet 3, the return air intake 2 and the air inlet 5 are connected in the casing 1, and the evaporator 6, the reheater 7, and the air supply fan 8 are provided. A, and an inverted U-shaped exhaust air passage B provided with a condenser 9 and an exhaust fan 10 in communication between the outside air intake 4 and the exhaust port 3, and the return air taken in from the return air intake 2 A first series passage C that leads also to the condenser 9 and a second communication passage D that guides outside air taken in from the outside air intake 4 to the evaporator 6 are provided, and a blowing hose 11 that can freely move the blowing position is provided. It is connected to the mouth 5. Since other configurations are the same as those in the above embodiment, description thereof is omitted.
[0013]
【The invention's effect】
In the first and second aspects of the invention, the blowing position of the blowing hose can be freely changed to locally air-condition, or the wind can be blown to the floor surface or under the floor to make the flooring material or underfloor space a heat medium or heat storage body. Easily change and adapt to various types of air conditioning such as air conditioning and underfloor air conditioning. Since the air supply port is on the lower side of the casing, the hose for blowing air can be easily brought to the floor. Because the outside air intake is facing down, it is safe without sucking rain. A single integrated air conditioner can perform all air conditioning operations such as ventilation / heating / cooling operation, outdoor air cooling operation, ventilation operation, supercooling / dehumidification / reheat operation. The outside air intake to the air supply air passage and the outside air intake to the exhaust air passage can be shared by one outside air inlet, and the return air intake to the air supply air passage and the return air intake to the exhaust air passage are unified. Since it can be shared by two return air intakes, the number of parts is reduced, making it possible to reduce the size and cost and make the installation easier.
In the third aspect of the invention, during the ventilation operation, only the return air can be supplied without taking the return air into the supply air passage, and only the return air can be exhausted without taking the outside air into the exhaust air passage. It saves energy without using power. In addition, if a damper mechanism is used to control the air volume of the outside air and return air in the supply air passage and the air volume control of the outside air and return air in the exhaust air passage, only the return air is exchanged between the room and the air conditioner while exchanging heat with the evaporator. It can also be warmed up by circulating between them.
In the invention of claim 4, since the pressure loss is reduced and the heat exchange efficiency is improved, a small fan can be used and noise can be reduced. The evaporator, condenser, and reheater can also be miniaturized and the air conditioner can be made compact.
