As shown in, the refrigerant connection port 7 for supplying and discharging the refrigerant is provided in the refrigerant pipe 4, and the heat of the hot water pipe 5 is less likely to be transferred to the refrigerant pipe 4, so that the hot water connection port 8 of the heat exchange unit 1 is provided.
A refrigerant connection port 7 that supplies and discharges the refrigerant to and from the refrigerant pipe 4 is disposed below. Further, a drain connection port 9 for discharging drain is arranged near the lower side of the refrigerant connection port 7 of the heat exchange unit 1.

As shown in FIG. 5, a blower 10 for supplying indoor air to the heat exchanger 2 is disposed behind the heat exchanger 2 of the heat exchange unit 1. An air outlet 11 is formed in the air outlet 11, and the wind direction of the air blown from the air outlet 11 is
A variable louver 12 for changing the vertical direction and a vertical wind direction plate 13 for changing the vertical direction are provided.

An opening 14 is formed in the front of the right side surface of the heat exchange unit 1, and an electric equipment box 15 is formed in the opening 14.
Is mounted so that one side thereof is located inside the heat exchange unit 1. A control board 16 for performing predetermined air conditioning control is housed inside the electrical equipment box 15, and a changeover switch 17 is provided on the front surface of one side of the electrical equipment box 15. Fixed pieces 20 are formed on the electrical equipment box 15 in a protruding manner, and the electrical equipment box 15 is fixed by fixing the fixed pieces 20 to the fixing flanges 18, respectively. In other words, FIG. 5 shows a state in which the electrical equipment box 15 is fixed, and FIG. 6 shows a state before the electrical equipment box 15 is fixed.

As shown in FIGS. 1 and 2, the heat exchange unit 1 is provided with an outer frame 100, which is formed by bending a thin steel plate into a U-shape or welding three steel plates. Has been done. The exterior frame 100 includes a heat exchanger 2, a blower 10, and a frame 1 that supports the blower 10.
No. 01, which forms the heat exchange unit 1 as shown in FIG.

Referring to FIG. 1, the blower 1 is attached to the frame 101 via a bearing 103 and a cushion rubber 105.
0 is attached and the blower 10 is connected to the motor 107. 109 is a bearing retainer, and 109A is a cushion rubber retainer. After this blower 10 is installed,
A frame back frame 111 is attached to the back surface of the frame 101, and a lower panel 113 and a lower metal fitting 115 are attached to the lower surface. A heat exchanger 2 is arranged upstream of the blower 10, and a heat insulating material 11 is provided above the heat exchanger 2.
7 is disposed, and the frame 101 and the heat exchanger 2 are covered with the outer frame 100 so as to surround all of these members.

However, according to this embodiment, the outer frame 1
The heat exchanger 2 is not only installed inside 00, but also this heat exchanger 2 is firmly fixed inside the exterior frame 100. That is, the outer frame 100
At the front corner (upper left part in FIG. 2) of the
Reinforcing metal fittings (reinforcing tools, other than metal) 121 are provided for the reinforcement of, and a mounting hole 123 is formed in the reinforcing metal fitting 121, and a pipe of the heat exchanger 2 is provided in the mounting hole 123. The plate 125 is fixed by screws (not shown). Note that, in FIG. 2, the heat exchanger 2 is shown by cutting along a cutting line L, and the illustration is omitted in the middle.

According to this, since the heat exchanger 2 is not only fixed by its own weight as in the conventional case but also fixed by screws, the heat exchanger 2 is left and right inside the exterior frame 100 during assembly and installation work. There is no need to move, and the workability can be greatly improved compared to the conventional one. Further, since the outer frame 100 is reinforced by the reinforcing metal fitting 121, the rigidity of the outer frame 100 is higher than that of the conventional one, and it is more resistant to deformation, and the squareness of the corner where the reinforcing metal fitting 121 is mounted can be accurately adjusted. Can be maintained. Further, since the reinforcing metal fitting 121 is provided at the front corner of the outer frame 100, it can be accessed from the front when fixing the tube sheet 125 of the heat exchanger 2 thereto, so that the fixing work becomes extremely easy. .

Next, the sensor portion will be described. The heat exchanger 2 is further provided with a temperature sensor 127 that detects the temperature of the primary air of the heat exchanger and a humidity sensor 129 that detects the humidity of the primary air. The heat exchanger 2 is provided with a refrigerant pipe 4 for acting as a cooler.
And the hot water pipe 5 for acting as a reheater are provided, and fine dry operation can be realized. Two sensors are arranged in parallel for the realization.

The temperature sensor 127 is attached to the front surface of the fin at the center of the heat exchanger 2 so that the temperature of the air on the primary side can be directly detected. The humidity sensor 129 is attached to the tube plate 125 at the end of the heat exchanger 2 via the attachment plate 131. Then, as is clear from FIG. 2, water droplets are attached to the upper end and the side edges of the mounting plate 131 so that the water droplets generated by dew condensation do not fall on the humidity sensor 129 so that the water droplets can be distributed to the left and right in the figure and flowed. A shield 133 is provided. As shown in FIG. 3, the humidity sensor 129 floats slightly tmm (for example, 0.5 mm) from the surface of the tube sheet 125 via the mounting plate 131 so as not to directly contact the tube sheet 125 of the heat exchanger 2. It can be installed in a closed state.

The humidity sensor 129 is arranged farther from the fins of the heat exchanger 2 in order to make it less susceptible to the influence of dew condensation water. Therefore, in the conventional case, the humidity sensor 129 is attached to, for example, the end of the adjacent electrical component box 15. However, in this case, the heat exchange unit 1 cannot be downsized. In order to solve this, in this embodiment, the humidity sensor 129 is attached to the tube sheet 125 at the end of the heat exchanger 2, and the water drop shield 133 is provided to reduce the influence of dew condensation. Replace the humidity sensor 129 with the tube sheet 1
It is attached in a state of being slightly floated from the surface of 25. Since the humidity sensor 129 is attached to the tube plate 125 on the side of the heat exchanger 2, the humidity sensor 129 is
The mounting position of is at a position where the wind speed is slightly weaker than the center side of the heat exchanger 2. Therefore, the air on the side of the heat exchanger 2 is attracted to the air having a high wind speed on the center side, and the humidity sensor 129 is weaker than the case where it is arranged on the center side of the heat exchanger 2. Since the air strikes at a slight angle, the humidity sensor 129 does not easily become a ventilation resistance.

According to this, by using the temperature sensor 127 and the humidity sensor 129, fine dry operation can be realized, and the heat exchange unit 1 can be downsized all at once.

The present invention is not limited to the above embodiment, but can be variously modified if necessary.
