Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separate type air conditioner.

[0002]

2. Description of the Related Art In recent years, the importance of ventilation has increased as the airtightness of houses has been increased, and a forced ventilation device is indispensable especially in high airtight and highly insulated houses to be constructed in the future. The amount of natural ventilation in the current house is about once per hour, and it is considered to be 0.5 or less per hour in the future air-tight and highly insulated house. The natural ventilation volume per hour is about 25 cubic meters for 6 tatami mats. On the other hand, the required ventilation is 20 cubic meters per person, although it depends on the work content and the number of people. Considering, for example, the case where a general family of four is in a 6-mat room, 55 cubic meters of active ventilation per hour is required.

At this time, the conventional separate type air conditioner does not have a ventilation function, and it is necessary to perform ventilation by opening / closing a window or the like or to provide a separate ventilation device.

Recently, there is an increasing tendency to install built-in air conditioners having ventilation devices even in general houses in Japan.

An example of a built-in type air conditioner having a conventional ventilation device will be described below with reference to the drawings. FIG. 8 is a schematic diagram showing a device configuration of a built-in type air conditioner having a conventional ventilation device. In the figure, 30
Is an air-conditioned room, 31 is a ceiling space, 32 is an outdoor space, 33 is an outdoor unit, and 34 is an indoor unit.
The outdoor unit 33 and the indoor unit 34 are connected by a refrigerant pipe 35 to form a refrigeration cycle. Indoor unit 3
Reference numeral 4 has an indoor heat exchanger 36, an intake air blower 37, and an exhaust air blower 38, and the intake air blow passage and the exhaust air blow passage are independent. Indoor unit 34 is ceiling space 31
The indoor unit 34 and the outdoor space 32 are connected by the first intake pipe line 39 and the first exhaust pipe line 40.
Further, the indoor unit 34 and the air-conditioned room 30 are connected by the second intake pipe line 41 and the second exhaust pipe line 42.

The air conditioner configured as described above supplies the outdoor air from the outdoor space 32 to the indoor heat exchanger 36 through the first intake pipe 39, and further the second intake pipe 41.
Through the air-conditioned room 30. Further, the air in the room from the air-conditioned room 30 is transferred to the second exhaust pipe 42 and the first exhaust pipe 4
It is discharged to the outdoor space 32 through 0. Thereby, air conditioning and forced ventilation can be performed.

[0007]

However, in the built-in type air conditioner having the above-mentioned conventional ventilation device, the large indoor unit 34 and the air duct must be housed in the ceiling or the like, and it is specially designed and installed when a new house is built. In addition, it requires a great deal of labor, man-hours, and cost for repair and replacement of equipment. In addition, since heating and cooling are performed by ventilation air, heat loss due to ventilation was large.

Further, in the built-in type air conditioner, since the air outlet is installed on the ceiling surface, the temperature distribution at the feet is particularly bad during heating.

In view of the above conventional problems, the present invention is a separate type air conditioner that can be easily installed in an existing house, can be easily repaired and replaced, and can be forcedly ventilated with less heat loss. The purpose is to realize.

Further, in addition to the above, it is an object of the present invention to improve temperature distribution and improve comfort.

[0011]

In order to solve the above-mentioned problems, a separate type air conditioner of the present invention has a compressor, an outdoor heat exchanger, and a refrigeration of a separate air conditioner having an indoor heat exchanger. Refrigerant distribution devices are provided before and after the indoor heat exchanger of the cycle, and a second outdoor heat exchanger is connected in parallel with the indoor heat exchanger to form a refrigeration cycle, and an indoor unit is provided with an indoor side. A compressor provided with a heat exchanger and an outdoor unit, a blower for the outdoor heat exchanger and the outdoor heat exchanger, a blower for the outdoor second heat exchanger and the outdoor second heat exchanger, and a refrigerant distribution device, Furthermore, the outdoor second heat exchanger and the air-conditioned room are connected by a blower duct, the opening of the air blower conduit to the air-conditioned room and the indoor floor placement blow-out unit are connected by a duct, and the air-conditioned room And an outlet provided in the outdoor unit And it constitutes by connecting the second blower duct.

Further, in addition to the above-mentioned structure, the separate type air conditioner of the present invention is provided with a plurality of air outlets which can be opened / closed arbitrarily in the indoor floor placed air outlet unit, and makes it possible to adjust the air volume and switch the air outlets by cooling / heating. It is a thing.

Further, the separate type air conditioner of the present invention is constructed such that the air outlet of the indoor floor placed air outlet unit is provided all around.

[0014]

With the above-mentioned means, the present invention can be easily installed in an existing house, can be easily repaired, and can be replaced with a device, and can further reduce heat loss due to ventilation and enhance comfort by air conditioning. It realizes a separate type air conditioner capable of forced ventilation.

Further, in addition to the above, the present invention improves the temperature distribution and improves comfort.
