Description

[Detailed description of the invention] This invention relates to the outdoor unit of an air conditioner, and by placing the heat collector on the suction side of the outdoor unit of the air conditioner, performance is improved in winter when the outside temperature is low. The purpose is to provide an outdoor unit for an air conditioner that can measure the

This invention will be explained below with reference to an embodiment shown in the drawings. 1 is an outdoor unit main body, 2a and 2b are a first vent hole and a third vent hole formed at the lower front of the main body.
, 2c and 2d are the second and fourth vents provided at the top of the main body, and 3 is an air-heating solar collector (hereinafter referred to as a collector) with an airflow passage 4 in the front. ), 5 is a glass plate, 6 is a heat collecting plate, 7 is a heat insulating material, 8 is a first ventilation path leading from the first ventilation port 2a to the second ventilation port 2c via the airflow path 4, and 9 is a second ventilation path from the third ventilation port 2b to the fourth ventilation port 2d via the rear of the heat collector 3, and includes a heat exchanger 10 and a blower 11 connected to an air conditioner. are doing. And switching damper 1
By switching 3, the air path from the second ventilation port 2c to the second ventilation path 9 via the first ventilation path 8 and the air path from the third ventilation port 2c to the second ventilation path 9 are selected. It is configured to be formed as follows. 1
2 is a communication port opened and closed by the switching damper 13.

In the above configuration, when the air conditioner is operated with the switching damper positioned as shown in FIG. The low-temperature outdoor air is heated as it passes through the first ventilation path 8 and enters the second ventilation path 9 through the communication port 12, where it is heat exchanged in the heat exchanger 10 and then transferred to the fourth ventilation path 8.
is discharged outdoors from the vent 2d.

On the other hand, in the summer, when the switching damper 13 is switched and the air conditioner is operated as shown in Fig. 2,
Outdoor air is drawn into the second air passage 9 through the third vent 2b, undergoes heat exchange with the heat exchanger 10, and then is discharged outdoors through the fourth vent 2d.

In addition, outdoor air enters the air flow path 4 in front of the heat collecting plate 6 heated by solar heat through the first vent 2a due to natural convection, and this air is returned to the outdoors through the second vent 2c. released.

In the embodiment, the heat collector 3 is installed vertically, but it goes without saying that it may be installed obliquely.

As described above, according to this invention, warm air heated by solar heat can be sent to the heat exchanger of the outdoor unit of the air conditioner in the winter, while hot air from the solar heat collector is not sent in the summer. In addition, since convection of outdoor air occurs within the solar heat collector, the heat exchanger will not be excessively cooled even when the outdoor temperature is low in winter, thus preventing a decrease in heating capacity. In addition, in the summer, it prevents the cooling capacity from decreasing and also prevents the heat collector from running dry, which has a great practical effect in that it does not cause problems such as thermal deformation or shortened lifespan. .
