Description

COOLING AND HEATING IN ONE BATHROOM TYPE AIR CONDITIONER}

The present invention relates to an air-conditioning combined bathroom type air conditioner, and more particularly, to an air-conditioning combined bathroom type air conditioner which can reduce component costs by eliminating the use of a relatively expensive four-way valve.

In general, an air conditioner is an air conditioner that is disposed in a room, a living room or an office, or a space such as a business store to maintain a comfortable indoor environment by controlling air temperature, humidity, cleanliness, and airflow.

In general, air conditioners are referred to as air conditioners for cooling indoors in summer. Some of these air conditioners reverse the flow of refrigerant in a refrigeration cycle to selectively perform cooling and heating functions, so-called heat pumps. There is a combined air-conditioning and air conditioner called a pump or an air conditioner for four seasons.

On the other hand, according to the change of living environment, most of the living spaces are equipped with bathrooms and toilets (hereinafter referred to as bathrooms), and these bathrooms always have water and drains to drain used water. Various fungi, bacteria, etc. are not only easy to breed, but also cause various odors, causing discomfort.

The use of the bathroom is not only fungi and odors, but it is also uncomfortable due to moisture condensation on the wall, glass, etc. due to the large amount of moisture generated during bathing, and in winter, it gives coolness due to the living room, the room and the temperature difference. There is a problem that may adversely affect.

In consideration of these problems, a bathroom-type air conditioner having a refrigeration cycle component is installed in the bathroom to cool or heat the bathroom.

By this configuration, in the cooling mode, the refrigerant compressed from the compressor 121 is condensed via the first heat exchanger 125 via the four-way valve 123, and passes through the capillary tube 133 to the second heat exchanger ( 129) to perform the cooling action to absorb the latent heat of evaporation. At this time, the air sucked through the second suction port 114 and passed through the second heat exchanger 129 and cooled by heat exchange is discharged into the room by the indoor fan 131 to perform the cooling operation.

Meanwhile, in the heating mode, the refrigerant compressed from the compressor 121 is condensed through the second heat exchanger 129, passes through the capillary tube 133, and absorbs heat from the first heat exchanger 125 so that the compressor 121 is compressed. Will return to.

At this time, the air sucked through the second suction port 114 and heat exchanged while passing through the second heat exchanger 129 is discharged to the room by the indoor fan 131.

By the way, in the conventional air-conditioning combined bathroom type air conditioner, the four-way valve 123, which is a relatively expensive component, is used to switch the refrigerant flow path in the cooling or heating mode, resulting in an increase in manufacturing cost. .

Accordingly, it is an object of the present invention to provide a combined air-conditioning and bathroom type air conditioner capable of reducing manufacturing costs by eliminating the use of a four-way valve.
