Abstract

PURPOSE:To miniaturize and lighten the weight of the above unit and improve the construction workability by providing an exhaust guide piece at a discharge outlet of an air-conditioning fan and a substantially L-shaped partition plate provided on the upper part of the air- conditioning fan along one edge of a whole heat exchanger. CONSTITUTION:Most part of air induced and drawn by an air-conditioning fan 10 from a fresh air intake port 2 and passing through one ridge surface of a whole heat exchanger 9 passes through discharge ports 11, 12 after passing through the air-conditioning fan 10 and is heated or cooled through a heat exchanger 13 and is supplied from air supply ports 6, 7, 8 into each room. On the contrary, the air in each room is returned from air return ports 4, 5 and is induced and drawn by the air-conditioning fan 10, and most part of the air is discharged from the discharge ports 11, 12 and is heated or cooled by the heat exchanger 13 and is further supplied into each room from the air supply ports 6, 7, 8. Part of the air flowing in from the ventilation ports 4, 5 is pushed into an exhaust passage 14 through an exhaustion guide piece 15 by the air-conditioning fan 10 and is transmitted in its heat to the side of an air supply flow passage 18 after passing through the one edge of the whole heat exchanger 9 and is exhausted from an exhaust port 3 to the outside of the rooms. Such a ventilation air-conditioning unit eliminates the use of a ventilation fan and hence is miniaturized and lighten the weight.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a ventilation air conditioning unit installed in the attic of a house or the like.

BACKGROUND OF THE INVENTION In recent years, houses have become more airtight due to the pursuit of comfort and the spread of energy saving ideas.

At the same time, with the spread of air conditioning and heating systems, houses have become airtight, and natural ventilation can no longer be expected, resulting in physiological problems due to insufficient ventilation and toxic gases emitted from building materials.

There have also been reports of psychological disorders. In order to solve this problem, a ventilation air conditioning unit is provided in which a heating and cooling device is provided with a ventilation device that exchanges heat between supply air and exhaust air.

As shown in FIG. 4, a conventional ventilation air conditioning unit of this type has an outside air intake port 51 in a main body 50 and an indoor air exhaust port 5.
2, air supply ports 55, 56, 57 for sending return air D53 and 54 and conditioned air to each room, and an indoor exhaust port 58 for exhausting indoor air. Inside the main body 50, indoor air flows into the interior of the main body 50 from the indoor exhaust port 58, passes through an exhaust fan 59, passes through one ridge of the total heat exchanger 60, and is exhausted from the exhaust port 52 through an exhaust flow path 61. , fresh air is taken in from the outside air intake port 51, and the intake fan 62
and an intake flow path 64 that passes through the other ridge surface of the total heat exchanger 60 and reaches the air supply communication port 63. On the other hand, an air conditioning room 66 adjacent to the ventilation room 65 has an air conditioning blower 67 and a heat exchanger 68 that passes hot or cold water, or a medium such as a refrigerant.
are provided corresponding to each of the air supply ports 55, 56, and 57. In this way, conventionally, the air is exhausted from the indoor exhaust port 58 via the exhaust fan 59 and through the exhaust flow path 61, and the air is ventilated from the outside air intake port 51 through the intake fan 62 to form the intake flow path 64. Indoor air returned from the return air ports 53 and 54 and the intake fan 6 from the outside air intake port 51
The fresh air taken in through the heat exchanger 60 and the fresh air that has been heat-recovered and heat-exchanged by the total heat exchanger 60 are heated or cooled by the air conditioning blower 67 through the heat exchanger 68. Air was supplied to each room from 56.57.

Problems to be Solved by the Invention In such a conventional configuration, when performing ventilation, the exhaust flow path 6
1 and an air supply fan 62 forming an air supply flow path 64, and each return air port 53.
Indoor air returned from the air intake port 54 and fresh air taken in from the outside air intake port 51 and subjected to heat exchange are taken into the air conditioning room 66, and the heated or cooled air is passed through the heat exchanger 68 to each air supply port 55, 56. Since an air conditioning blower 11!67 is required to supply air from 57 to each room, the main body 50 itself becomes large in volume and weight, and is not easy to install, so it may be necessary to install it in the ceiling in some houses. The problem was that it was difficult.
