Description

[Detailed description of the invention] (Industrial application field) This invention relates to an outside air intake and exhaust device in a heat pump type air conditioner that uses air as a heat source.

(Conventional example) In an air source heat pump type air conditioner (so-called wall-through air conditioner) that takes in and exhausts outside air from the wall surface, as shown in Figure 4, there is an outside air intake pipe and an exhaust pipe on the back of the air conditioner installed indoors. It is common practice to install a pipe and connect it to the outside air inlet and outlet installed on the back wall, respectively, and use the outer wall as a chamber with partition plates for air intake and air outlet. Connections on the back are also known.

(Problems to be solved by the invention) As mentioned above, in a wall-through air conditioner in which the opening in the wall is connected to the outside air intake and exhaust at the back of the air conditioner, there is a connection part as shown in Figure 4. As shown in , a space (E) is required between the air conditioner (A) and the wall (C), which narrows the floor area when installing the air conditioner, which not only hinders the effective use of the floor area, but also makes it difficult to connect the air conditioner in that space. is often difficult.

(Means for Solving the Problems) The present invention eliminates the above-mentioned disadvantages of the conventional system and makes it easy and convenient to connect external air to the wall for intake and exhaust of air as a wall-through air conditioner, thereby making the installation of air conditioning equipment advantageous. In a heat pump air conditioner that uses air as a heat source and is installed indoors and takes in outside air from the wall and exhausts it, each chamber for outside air intake and exhaust is installed at the top of the air conditioner body. It is detachably and movably attached to the air conditioner main body and connects the outside air intake pipe and outlet pipe of each chamber to the air conditioner main body, respectively, and connects the outside air intake pipe and exhaust pipe of each chamber to each other. It is connected to an outside air inlet and an air outlet opened in the wall.

(Example) Embodiments of the present invention will be described with reference to the drawings.

In the drawing, reference numeral 1 denotes the main body of a heat pump type air conditioner, which includes, for example, an outdoor fan a, an outdoor heat exchanger b, an indoor fan c, an indoor heat exchanger d, a compressor e, and other air source heat pumps (not shown). It has built-in equipment as a type air conditioner.

2 is a chamber for taking in outside air, and 3 is a chamber for exhausting outside air. These chambers 2 and 3 are formed separately from the air conditioner main body 1, and are detachably attached to the upper part of the air conditioner main body 1. . In the illustrated example, the chambers 2 and 3 are formed separately, and are fixedly attached to the main body 1 using elongated holes 4 and set screws 5 so that the chambers 2 and 3 are arranged side by side and their longitudinal positions can be adjusted. However, the movement adjusting means is arbitrary, and both chambers 2 and 3 may be formed by partitioning the inside of one chamber with a partition plate in the middle.

When installing the outside air intake chamber 2, the outside air intake port 2a provided on the lower surface is connected to the communication port 6 opened in advance on the upper surface of the air conditioner main body 1, and the outside air intake pipe 2b provided protruding from the back side of the chamber 2 is connected to the wall. A, and when installing the other exhaust chamber 3, connect the outlet 3a provided on the lower surface to the communication port 8 provided on the upper surface of the air conditioner main body 1, and An outside air exhaust pipe 3b protruding from the back surface of the wall A was connected to an air outlet 9 provided in the wall A in advance.

(Function) In the above configuration, each chamber 2, 3 is arranged in accordance with the positions of the communication ports 6, 8, the suction port 7, and the air outlet 9, which are provided in advance on the top surface of the air conditioner main body 1 and on the wall A surface, respectively. The inlet 2a intake pipe 2b, the outlet 3a and the exhaust pipe 3b can be moved and attached to each of them so that they can be properly connected, and by these connections, outside air can be introduced into the air conditioner main body 1 and exhaust can be removed. I can make it happen.

(Effects of the invention) According to the invention, the outside air intake chamber and the exhaust chamber are formed separately from the air conditioner main body, and are movably attached to the air conditioner main body. There is no need to provide a space for a connection between the air conditioner main body and the wall surface as in the past, and the air conditioner main body can be installed close to the wall surface, so the space required for installation on the floor is small. The floor surface can be used effectively, the connection with the opening in the wall is extremely simple, and the movable chamber allows the connection to be made in an appropriate arrangement according to the site situation.
