Abstract

PURPOSE:To get the most comfortable air conditioning feeling by a method wherein changing- over damper structures are provided at downstream sides of air blowing circuits for an evaporator and a condensor, respectively, air of the air blowing circuit for the evaporator is bypass fed to the air blowing circuit for the condensor and then the air of the air blower for the condensor is fed out to a front surface of the device. CONSTITUTION:When a cold air is required, a cold air of which heat is absorbed by an evaporator 2 is discharged out of a cold air diffuser 7a at the front surface and reaches an upper body of a user. An air blowing circuit 8 for a condensor has a closed damper 12 and has the same structure as that of a partition wall 6, resulting in that blown air for the evaporator and blown air for condensor are mixed to each other. When a dehumidifying operation is performed, the damper 12 is opened and the air of which heat is absorbed by the evaporator 2, cooled and dehumidified is fed into the air blowing circuit 8 for the condensor through an upper opening 6a of the partition wall, passes through the condensor 3. At this time, the air becomes a dried air slightly higher than a temperature of a living room under a thermal radiation of the condensor 3 and further the air is discharged out of a radiation air diffuser 8a at a rear surface of the device. As a result, the cold air is blown out of the upper part of the front surface of the device and the dehumidified air is blown from a direction where the air is directly struck against the user so as to improve the air conditioning feeling.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to an integrated air conditioner that performs local heating, cooling, and dehumidification when the unit is used in a living room.

PRIOR ART FIG. 8 1 Main This shows a conventional integrated air conditioner. 1 1L, air conditioner unit; 2 is evaporation; 3 is condensation; 1 is compressor; 9 is electric box; 6 is partition wall 10 that partitions the evaporator air blowing circuit 7 and the condenser air blowing circuit 8; electric heating device 121; L is air for the condenser As shown in the figure, the air outlet 7 of the evaporator air blower circuit 7 is located on the downstream side of the damper 12 as shown in the figure.
The operation of the air conditioner configured as above will be explained below, even if the electric heating device 10 is installed on the way to the damper 12ζ. The evaporator air blower circuit 7 and the condenser air blower circuit 8 are connected to the rear of the electric heating device 10.
The cold air that has passed through the evaporator air blower circuit 7 is discharged from the usage side air outlet 7a, giving the user a feeling of cold air. In addition, the condenser blown air (by the partitioning action of the damper 12, the air other than the side where unit 1 is used (?1 in this figure)
It is discharged to the air outlet 8a on the top surface). On the other hand, during heating (
Damper 12 {Yo} is located at the position of the broken line shown in Figure 8,
Both the condenser blower circuits 7 and 8 use only air blowing without refrigerant heat exchange, and the air from the condenser blower circuit is passed through the electric heating device 10 that generates heat while being energized, and mixed with the air from the evaporator blower circuit. At the top, the air is discharged to the use-side outlet 7a to provide a feeling of warm air. Also, during dehumidification (friend), in the same operation as during heating, the electric heating device 1o is not energized, and the air is guided from the air blowing circuit for the condenser, and the air is radiated by the condenser.
The problem to be solved by the invention is that it mixes with the cold air from the evaporator and is discharged from the usage side outlet 7a. With the configuration as shown in Figure 8, the cold air is discharged from the user side air outlet (the cold air is blown out from above and is effective in increasing the cooling sensation of the user's upper body). It has the disadvantage that it does not have the effect of bringing a warm feeling to the lower body (feet), and when using dehumidification (it is easy to use low-humidity, low-temperature air that has passed through the evaporator, and high-temperature air that has passed through the condenser, which is the same as the living room). This has the drawback that only air with absolute humidity is mixed, and the blown air is not sufficiently dehumidified.The present invention, in view of the above problems, blows cold air and hot air into upper and lower parts, respectively. The dehumidifying air is designed to have a structure in which the air that has passed through the evaporator of the dehumidifier unit passes through the condenser. In order to solve this problem, the present invention {1. It has a structure that branches and directs the air to either of the air outlets provided on the rear side of the unit, and the air passing through the evaporator is guided to the rear side of the unit.The air blower circuit for the condenser is re-stormed from the rear side of the unit. In addition, according to the present invention, the air passing through the evaporator led from the branch switching damper for the evaporator air is provided with an air passage passing through the unit. This air conditioner is equipped with a structure that joins the condenser blower circuit at an upstream position of the condenser.On the other hand, the present invention also provides an air conditioner that can be opened and closed upstream of the air outlet of the condenser blower circuit. A damper structure is provided, and an air outlet is provided on the back side of the unit for air passing through the condenser, and an air passage passes through the unit from this damper part to an air outlet provided on the front side of the unit where it is used. The damper has a condenser blower circuit structure that allows the air force passing through the condenser to be branched to either the front or rear side of the unit where it is used.

Furthermore, in order to enable the unit of the present invention to be used as a heater, a branch switching damper provided on the downstream side of the condenser air blowing circuit and an air outlet provided on the front surface of the unit on the user side are connected. An electric heating device is housed in the middle of the air blower circuit.

Effects By using the above means, the following effects can be obtained by switching the dampers provided in the evaporator air circulation circuit and the condenser air circulation circuit of the air conditioning unit of the present invention. If you want to obtain the desired result (by placing the evaporator blower circuit damper in the position where the front air outlet on the unit use side is open, and the condenser blower circuit damper in the position where the rear air outlet of the unit is open), the evaporator Cold air ('!S) is blown out to the front of the user side.

It is possible to change the exit. L & evaporator air blower circuit damper when using heating
Set the front air outlet on the user side of the unit to a closed position, and force exchange the air at the same temperature as the room that passed through the evaporator without using the refrigeration cycle. It penetrates to form a blower circuit that is introduced into the condenser blower circuit. On the other hand, the damper of the condenser air blower circuit closes the condenser air outlet and positions the air to be blown to the air outlet on the front side of the unit where the unit is used, so that the air introduced from the evaporator air blower circuit
The air sucked in from the air intake port of the condenser blower circuit joins together and passes through the electric heating device that is energized.
It is overheated and gives the user a feeling of warm air. When using the air conditioner according to the present invention, it is possible to select the locations of the cold air and hot air outlets separately, and the locations of the dehumidifying air outlets can be temporarily set to either the front or rear side on the usage side. It can be selected and has the effect of further enhancing the feeling of air conditioning provided to the user.
