Abstract

PROBLEM TO BE SOLVED: To enable a compact and low-noise construction, to restrict an increase of power consumption, to supply fresh outside air from outdoor into a living space, to remove contaminated air in the living space efficiently and in a short time, to eliminate an irregular temperature distribution in the living space and to prevent an occurrence of condensate and mold on a ceiling surface and a wall surface. SOLUTION: In this ventilator, an exhaust device 7 is provided with an exhaust blower 9 in the vicinity of an inlet formed in an approximately central portion of a ceiling surface of a living space 2, while an air supply device 12 comprises a plurality of outlets 13 which are formed in wall surfaces or corners 5 of the living space 2 and are directed in the same direction. The exhaust device 7 and air supply device 12 are independently and variably controlled so as to produce a whirling air flow 39 and a vortex air flow 40 such as a tornado in the living space 2. Owing to such a construction, with a relatively simple construction, contaminated air in the living space 2 can be efficiently ventilated in a short time.

いた。Next, the indoor heat exchanger 15 for cooling and heating the living space 2 in the air supply device 12 is connected to the outdoor air conditioner 20 by a connection pipe 26 through which the refrigerant passes. That is, the outdoor air conditioner 20 includes a compressor 21 for compressing the refrigerant, a four-way valve 22 for switching the flow of the compressed refrigerant during cooling and during heating, and as a radiator during cooling operation.
An outdoor heat exchanger 23 that acts as a heat absorber during heating, an outdoor blower 24 that effectively acts on heat radiation and heat absorption thereof,
An orifice 25 for effectively reducing the pressure of the refrigerant was incorporated.

5, a compressor 21 in the outdoor air conditioner 20, a four-way valve 22, an outdoor heat exchanger 23, an orifice 25, and a connection pipe 26 constitute a refrigerant circulation cycle. During the cooling operation, the indoor heat exchanger 15 absorbs heat. The refrigerant thus drawn was sucked into the compressor 21 through the connection pipe 26, and when compressed and discharged there, passed through the four-way valve 22, and released heat from the outdoor heat exchanger 23 to the outside by the outdoor blower 24. . The refrigerant that has finished releasing heat is depressurized by the orifice 25 and returned to the indoor heat exchanger 15 again.

な環境が維持されていた。During the heating operation, the flow of the refrigerant becomes a reverse circulation cycle at the time of cooling, and the refrigerant absorbed by the outdoor heat exchanger 23 passes through the compressor 21, the four-way valve 22, and the indoor heat exchanger 15 to the indoor. Heat was released by the air supply blower 17 and warm air was sent into the living space 2. The refrigerant that passed through the indoor heat exchanger 15 passed through the orifice 25 and was returned to the outdoor heat exchanger 23 again. By this cooling and heating, the temperature of the living space 2 was adjusted, and a comfortable environment was maintained.

No. 0 was built in the airflow control unit 29 connected to the respective component parts by the connection harness 37. An operation panel 31 for operating and stopping the ventilation device and setting conditions for the living space 2 is also connected to the airflow controller 29. With this configuration, an appropriate signal is transmitted from the airflow control unit 29, and each component is operated efficiently, so that the living space 2 is maintained comfortably.

However, a complicated flow occurred around the corner 5 and the wall 4.

The air was blown into the living space 2 from several outlets 13 provided on the floor 6 by the indoor air blower 17.
Then, the contaminated air in the living space 2 is sucked from the suction ports 8 provided at several places on the ceiling surface 3 and returned to the air conditioner 42.

た。However, if a conventional ventilator is used as a ventilation means for a dwelling space of a highly airtight house such as that found in a highly airtight and highly insulated house, leakage to the outside will not occur. Because of this, the ventilation resistance was high and the air volume was low, so the ventilation performance had to be greatly improved. Therefore, in order to improve ventilation performance, increase the size of components such as the indoor air supply blower of the air supply device, the exhaust blower of the exhaust device, and the air supply duct and exhaust duct.
Alternatively, the number of revolutions of the blower had to be increased.

大を招くと言う課題を有していた。When increasing the size of the component equipment, it is practical to install a large air supply device, an exhaust device, an air supply duct, or an exhaust duct below the narrow ceiling of a house, even in view of the outer shape, weight, and cost. After all, it was so difficult that he had no choice but to increase the speed of the blower. As a result, as a matter of course, there is a problem that the living space is troubled by the noise of the blower and causes an increase in power consumption.

り除くには相当時間が掛かるという課題も有していた。When a large-sized air supply device, an exhaust device, an air supply duct, an exhaust duct, and the like can be installed above the ceiling, the conventional ventilation device can almost always be used for the air flow in the living space. Since the stagnation occurs in the corners of the living space, the polluted air is inevitably left in the living space, and it takes a long time to remove all of them.

Although it is an objective and an important design factor, in the above-mentioned conventional examples, since the stagnation portion of the flow occurs in the living space, uneven temperature in the living space and ceiling surface There is also a problem that it is not enough to prevent condensation and mold on the wall and the wall.
