Abstract

PURPOSE:To miniaturize a ventilation air-conditioning device by forming an air supply passage extending from a fresh air introduction inlet through a heat exchanging element to a blow-off outlet of a fan and an exhaust flow passage extending from an indoor air suction inlet to an indoor air exhaust outlet, and further a circulation flow passage extending from the indoor air suction inlet through the heat exchanger into each room. CONSTITUTION:Once a motor 13 is rotated and a blade 12 is rotated, fresh air is sucked into a body from a fresh air introduction inlet 5. The sucked fresh air passes through a heat exchanging element 4 and is sucked into a casing 11, and is further fed from a blow-off outlet 16 to a heat exchanger 2. After air-conditioned, the fresh air is supplied into each room from a discharge outlet 8. On the contrary, returned air from each room enters the body 1 from an indoor air suction inlet 7, part of which is fed into each room after the passage of the heat exchanger 2 with the other remaining part of the air is communicated with a circulation passage 17 from the blow-off outlet 16, going around toward the lower side of an air fan part and passes through the lower portion of the casing 11. The air is further heat-exchanged with the fresh air through the heat exchanging element 4 and is exhausted from an indoor air exhaust outlet 6 to the outside of each room. Thus, there is eliminated the use of a ventilation fan and the device is miniaturized with the number of motors reduced and for provision of energy saving operation.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heat exchange air conditioning unit installed in the attic of an apartment complex or a single-family house.

BACKGROUND OF THE INVENTION In recent years, houses have become more airtight and highly insulated, and ventilation air conditioners that not only provide air conditioning but also provide ventilation at the same time as air conditioning have become popular.

Conventionally, this type of ventilation air conditioning system has had a configuration as shown in FIG. That is, the main body 51 has a heat exchange air 52 for air conditioning through which a medium passes through the inside, a blower section 53 for air conditioning, a heat exchange element 54, and a blower section 50 for ventilation. , an indoor air exhaust port 56 , an indoor air suction port 57 , and a discharge port 58 . The air conditioning blower section 53 includes an air conditioning motor 59, air conditioning blades 60, and an air conditioning casing 61, and the ventilation blower section 50 includes a ventilation motor 62, ventilation blades 63, 64, and a ventilation casing 65. ．． It consists of 66.

In this way, the conventional ventilation air conditioning unit has an outside air inlet 5.
The fresh outside air coming in from 5 is passed through the ventilation casing 65.
The air is sucked in by the rotation of the ventilation blades 63 caused by the rotation of the ventilation motor 62, and is sent into the air conditioning blower section 53 through the heat exchange element 54. Furthermore, the rotation of the air conditioning vane 60 caused by the rotation of the air conditioning motor 59 causes the heat exchange air 52 to be blown, and the conditioned air is blown into the room from the discharge port 58. In addition, a part of the indoor circulating air sucked in from the indoor air suction port 57 is circulated indoors again from the air conditioning blower 53 as described above, but some of the air is passed through the ventilation casing 6.
The air is sucked in by the rotation of the ventilation blades 64, passes through the heat exchange element 54, and is exhausted to the outside from the indoor air outlet 56 while performing heat exchange ventilation with the outside air.

Problems to be Solved by the Invention In such a conventional configuration, ventilation and air conditioning are performed at the same time, but since the air conditioning blower section 53 and the ventilation blower section 50 are each incorporated inside the main body, only the space for the air conditioning blower section 53 is used. In addition, space is required for the ventilation blower section 50, which increases the size of the main body, and the power consumed by both the air conditioning motor 59 and the ventilation motor 62 becomes uneconomical. There was an issue.

The present invention solves the above-mentioned conventional problems, and provides a heat exchange air conditioning unit that performs air conditioning and ventilation with a single motor, reduces the size of the ventilation air conditioner, and consumes less power. The purpose is to

Means for Solving the Problems In order to solve the problems, the present invention has a heat exchanger, an air blower, and a heat exchange element inside a main body, and the main body has an outside air inlet and an indoor air exhaust. an air outlet, an indoor air suction port, and a discharge port, forming an air supply flow path from the outside air inlet through the heat exchange element to the air outlet of the blowing section, and air flowing from the indoor air suction port to the air outlet. Heat is recovered by a heat exchange element, forming an exhaust flow path leading to the indoor air outlet, flowing in from the indoor air inlet, passing through the heat exchanger of the blowing section, and circulating from the outlet to each room. It has a flow path formed therein.

Function: With this configuration, the air supply flow path from the outside air inlet through the heat exchange element to the ventilation section, and a portion of the air that has flowed in from the indoor air suction port go around below the ventilation section and pass through the heat exchange element. These air supply channels are connected to the exhaust flow channel, and the air discharged from the indoor air intake port and the air outlet of the blower passes through a heat exchanger to generate heated or cooled air. will be discharged into each chamber from the discharge port.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2.

In FIG. 1, a main body 1 has a heat exchanger 2 for air conditioning, a blower section 3, and a heat exchange element 4 for heat recovery inside a main body 1, and a side surface of the main body 1 has a An outside air inlet 5, an indoor air outlet 6 for discharging indoor air, indoor air suction lowers provided on both sides that return air from each room, and an outlet 8 for blowing air out into each room. The heat exchange element 4 has a main body 1 in an air supply flow path 9 and an exhaust flow path 10.
A casing 11 is provided on the leeward side of the air supply flow path 9 and communicates with the indoor air suction lower, and has blades 12 and a motor 13. With the motor 13 symmetrical on both sides, the casing 14 The vane 15 is the exhaust flow path 10
It is formed on the windward side of Further, a circulation flow path is provided in which air flows in from the indoor air suction lower, passes through the heat exchanger 2 from the air outlet 16 of the blower section 3, and reaches the discharge port 8, so as to communicate with the air supply flow path 9 and the exhaust air flow path 10. 18 is formed.

On the other hand, in FIG. 2, the outlet 16 of the casing 11.14 communicates with the heat exchanger 2 on the lower side, and the return path 1 provided below the casing 11.14.
