Description

[Detailed Description of the Invention] The present invention relates to a separate type air conditioner in which an indoor side and an outdoor side are separated, and its purpose is to maintain the aesthetic appearance of a house after installation and to save resources in equipment. That is.

Conventionally, an outdoor unit in this type of air conditioner has a heat exchanger, a fan, a fan motor, a compressor, etc. covered with an exterior to form a unit. Although this structure makes it easy to transport and install the outdoor unit, it may not be suitable for aesthetic reasons such as the appearance of the house after installation or the space it takes up on the ground.

The present invention eliminates the drawbacks found in the above-mentioned conventional air conditioners.

Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

In the figure, 1 is a cloth foundation for a house, on which a foundation 2 is fixed, an outer wall 3, a ceiling 4, and a floor 5.
A house is composed of: 6 indicates the outdoor ground, and 7 indicates the space under the floor of a house. Inside the room, an indoor unit 8 having a well-known structure is installed on the wall, and a compressor 9 is installed in the space 7 under the floor. The condenser 10 for radiating heat outdoors is
It is attached to the outer wall 3 by appropriate means such as metal fittings. Reference numeral 11 denotes a cover that covers the condenser 10, the upper end of which is open toward the top, and the opening 14 of which extends close to the eaves 15. Further, motors 13 for driving auxiliary fans 12 having multi-blade blades are installed inside the cover 11, and the lower part of the cover 11 communicates with an opening 16 formed in the cloth foundation 1. There is.

Here, the indoor unit 8, compressor 9, and condenser 10 are connected to each other through refrigerant piping to form a well-known refrigeration cycle.

In the above configuration, as the air conditioner operates, the refrigerant that absorbs heat in the indoor unit 8 is compressed by the compressor 9, reaches the condenser 10, and radiates heat there.
As mentioned above, the condenser 10 is provided in the space between the outer wall 3 and the cover 11, and as the temperature of the condenser 10 rises, the air in that space is heated and becomes an upward airflow, which cools the condenser 10 by convection. do. Since the lower part of this cover 11 is connected to the opening 16 of the cloth foundation 1, cooling air is introduced from under the floor. Further, if the opening area of the opening 16 is insufficient, the auxiliary fan 12 is used to make up for the insufficiency in order to assist upward flow due to convection.

Therefore, for cooling the condenser 10, the air under the floor, which is lower than the outside air, is effectively used, which is efficient. In addition, the compressor 9 installed in the underfloor space 7 is covered with a soundproofing material 17 to prevent noise, and the whole is covered with a box body 1.
Since it is surrounded by 8, the soundproofing effect is also great. Furthermore, since the tip of the cover 11 is open near the eaves 15, rainwater does not enter.

As is clear from the above embodiments, the air conditioner of the present invention has a compressor that constitutes a refrigeration cycle installed under the floor of a house, and an outdoor heat exchanger that constitutes the refrigeration cycle together with the compressor. attached to the outer wall of the house, further covering the compressor with a box body equipped with a soundproofing material inside, and providing a cover covering the outdoor heat exchanger on the outer wall, and opening the upper end of the cover, connecting with an opening provided in the cloth foundation of the house at the lower end to form a ventilation passage within the cover;
A blower device is installed in this ventilation passage, and the outdoor heat exchanger is cooled using the air under the floor, which has a lower temperature than the outside air, by using the rising air of warm air generated by the heat generated by the outdoor heat exchanger. As a result, the heat exchange efficiency is high, and natural convection is used to discharge the cooling air, so the blower only needs to be operated auxiliary, and it is compact and consumes less power. The outdoor heat exchanger is installed on the exterior wall of the house, making effective use of wasted space, requiring an extremely small installation area, and reducing the vibration and noise of the compressor by installing a box equipped with soundproofing material. It has various advantages, such as less transmission to the outside by the body and quiet air conditioning.
